What is Bioactive Dentistry? A Review

What is Bioactive Dentistry? A ReviewWhat is Bioactive Dentistry? A Review

As we all know, the traditional materials commonly used in dentistry are passive and inert, i.e. they exhibit little or no interaction with body tissues and fluids. In the past, materials were thought to be ideal and biocompatible based on their ability to sustain without interacting with the oral environment. However, the current trends are changing due to the advancements in material science. Many of the advanced materials are required to be functionally beneficial, playing an active part, thereby working with dental tissues to remineralize and heal them.

Materials used in dentistry can be classified as bioinert (passive), bioactive, and bioresponsive or smart materials based on their interactions with the environment. As the name suggests, a bioactive substance is one that has an effect on a living organism, tissue or cell. The concept of bioactivity was first introduced in 1969 and later defined by Cao and Hench in 1996. In general, it refers to a specific property of a material that has an effect on or will elicit a response from a living tissue or cell, such as induc­ing the formation of hydroxyapatite. Perhaps the benefits of fluoride release from materials attracted the use of active materials rather than passive ones in dentistry. However, bioactivity is not just limited to fluoride release and the conversion of hydroxyapatite to its stronger form of fluorapatite anymore! The definition of bioactivity in dentistry is expanding by leaps and bounds due to the emergence of bioactive dental materials in the market.

Some of the bioactive materials available are calcium hydroxide, mineral trioxide aggregate (MTA), calcium enriched mixture (CEM), Biodentine, Doxadent, Ceramir, Bioaggregate, Activa BioACTIVE restorative material, MTYA1-Ca filler, tetracalcium phosphate (TTCP), Theracal, sol-gel-derived bioactive glass (BAG) ceramic containing silver ions (Ag-Bg), calcium phosphate, fluoro calcium phosphosilicate, novel endodontic cement (NEC), endo sequence root repair material.

The ideal properties of bioactive materials are: bactericidal or bacteriostatic, sterile, stimulate reparative dentine formation and maintain pulp vitality. The bioactive materials have been put to various uses in dentistry such as pulp capping material, permanent restorations, root canal therapy, dentinal tubule occlusion in dentinal hypersensitivity cases, to act as scaffold to help in the regeneration of bone tissue, for tooth repair & regeneration, periodontal regeneration, to promote tooth remineralization, bone grafts, implant coating etc.

Bioactive materials are currently a significant topic of interest in restorative dentistry for regeneration, repair and reconstruction. This is evidenced by the change in the com­positions of restorative materials away from inert “fillers” and more toward being biologically adaptive materials. A bioactive dental restorative material is one that forms a layer of hydroxyapatite when immersed in a simulated body fluid or a solution containing inorganic phosphate. This is possible by induction of various growth factors to stimulate nat­ural mineralization. Imagine being able to re-calcify a carious tooth?? Sounds amazing! Isn’t it?? It’s no longer an imagination! The advent of bioactive dental materials has made it a possible reality.

The luting and restorative materials that have been used in the past merely restore the form and function of the tooth, but are not influential on the activity of the oral environment. They do not provide a continuous seal, resulting in micro-leakage and marginal failure of crowns, inlays, and veneers. Furthermore, these materials typically function at a continuous and constant pH, which causes the materials to fail, creating crevices where plaque can build up and secondary caries even before the restoration fails. On the other hand, bioactive restor­ative materials, such as bioglass, glass-ceramic, calcium phos­phate ceramic, composites, and coatings, are able to stimulate the biological tissue of the tooth and/or bond to living tissues. Therefore, the hope for bioactive materials is that they will prevent micro-leakage by forming apa­tite, which will provide a continuous seal to the margins between the restoration and tooth thereby extending the life of the restoration. Moreover, bioactive materials may also help to re-establish minerals lost to caries.

Apart from that, bioactive materials are considerably less harmful to local and generalized tissues. Additionally, these materials have been shown to considerably enhance the aesthetic outcome of restor­ative dental procedures. This evolution of materials and compo­sitions that display greater interactions with tooth structure is the drive for the future, as seen by the following trend of bioac­tive material compositions from zinc phosphate to polycarboxylate to glass ionomer cements.

ACTIVA BioACTIVE-RESTORATIVE (Pulpdent) is a composite resin that is more bioactive and releases more fluoride than glass ionomer cement, which is particularly useful for patients with high caries indices. There are a composite material, Beautiful II and Beautiful Flow Plus (Shofu Dental) with a Giomer glass filler. While Giomers do not release calcium and phosphate ions, they do release many other basic ions that can help buffer the effects of the acid environment in the oral cavity helping to inhibit plaque accumulation on restorations and at the margins. Examples of luting agents currently available in the market which have been shown to have bioactivity are ACTIVA BioACTIVE-CEMENT (Pulpdent), Ceramic Crown and Bridge (Doxa), and biochem Universal BioActive (NuSmile).

Experiences with calcium hydroxide as a lining material for resto­rations located close to the pulp has greatly influenced the initia­tive to develop bioactive lining materials rather than just biocompatible ones. Placement of a bioactive liner in deeply carious teeth can help remineralize and rebuild the remaining affected dentin after infected dentin removal, returning to healthy dentin. Examples of bioactive cavity liners available in market include ACTIVA BioACTIVE-BASE/LINER (Pulpdent) and TheraCal LC (BISCO Dental Products), and both have been shown to exhibit bioactive properties based on the mentioned definition of bioactivity. The calcium silicate chemistry of TheraCal LC enables this material to be used on pulp exposures. Biodentine (Septodont) is a tricalcium silicate material, which can be used as a bioactive build-up material where large areas of tooth structure are missing, and when a pulp exposure or root perforation may exist. While some of the more heroic cases may eventually still require endodontic therapy, there will be many cases that will respond favorably thus avoiding an additional procedure and preserving the vitality of the tooth.

Dentinal hypersensitivity is traditionally treated by occluding the dentinal tubules. The conventional toothpaste or professional prophylaxis materials use a soluble source of fluorides such as sodium fluoride and sodium monofluorophosphate which are washed away and lose their effect more quickly. Nowadays toothpaste incorporating bioactive glass has the additional benefit of remineralization, thereby significantly reducing dental decay apart from their ability to solve tooth sensitivity. They adhere to tooth structure through a special polymer, from where it slowly dissolves ions that form Fluorapatite, over an 8–12 hour period to make teeth more resistant to acids from food. One such example is the Elsenz toothpaste (Group Pharmaceuticals Limited) which releases the controlled level of fluoride for up to 12 hours.

The area of regenerative dentistry has been affected more by the use of bioactive materials than by biocompatible materials. Dentin extracellular matrix proteins contain growth factors to promote tooth healing and pulp regeneration via stimulation of pulp stem cells. Denton can stimulate reparative mineralization of the coronal pulp and occlusion of the lumen of the root canal. Biomaterials such as Emdogain contain porcine proteins that help in periodontal regeneration following gum disease or injury. N-Butyl-2-cyanoacrylate is widely used for filling and repair of bone defects. Implants coated with hydroxyapatite are available to promote osteogenesis and bone healing.

The emergence of bioactive materials is a boon for dentistry and a promising alternative to their inert counterparts. Restorations and adjunctive materials will no longer just occupy the space between themselves and the surrounding tooth, but will help repair and sustain healthy tooth structure allowing our patients to have a better chance to enjoy a healthy dentition throughout their lifetime! However, there is scope of improvement and further development of bioactive materials used in dentistry. We are yet to reach a stage where materials can completely emulate biological systems.

Technology expands the scope of general practice

Technology expands the scope of general practiceTechnology expands the scope of general practice

The future prospects of dental profession lie in modern technology. Latest dental technology plays a crucial role in empowering general dentistry and provides the best treatment to its patientDental field has dynamically evolved in scientific understanding and technology. This has offered better dental solutions and broadened the horizons which enable dentists to improve the quality of treatment being provided to patient.

In what ways can technology improve our dental practice? Well, it has facilitated simplification of complex procedures that dentists once dreaded to take up. This has helped in providing superior and comfortable patient experiences for them. A host of innovations in dental care have created avenues for easy access and lower costs of dentistry. Newer technologies enable patient to be treated with less-invasive methods and better care. In a short span of time, dentists are providing the high standard treatment to its patient. Technological developments have transformed modern-day dental practice significantly beginning from diagnostics to high-end surgical procedures.

Intraoral Camera

Any patient walking into a dental clinic will be intraorally examined first. Intraoral camera is a lightweight tool to produce accurate images of teeth and oral cavities. This camera is available in most of the dental clinics to visualize dental problems. They serve as an excellent patient education tool with higher case acceptance rate and improved patient communication.

Digital Radiography and Teleradiology

Radiovisiography (RVG) has digitalized diagnostic dentistry which eliminated the requirement of dark rooms and processing. In a few seconds, the radiographs can be viewed on the monitor. They offer image enhancement which provides precision in the analysis of minute features such as cracks and caries that cannot be sensed using traditional film-based radiographs. Teleradiology has made it possible to take the opinion of radiologists and other dentists staying far off places.

Cone Beam Computed Tomography (CBCT)

Cone beam computed tomography (CBCT) has gained widespread popularity in recent times with vast areas of applications in dentistry. It has revolutionized implant planning enabling precise implant placement, viewing root canal anatomy and missed canals in endodontically treated teeth, the location of impacted teeth, dental traumatic injury detection, vertical root fracture detection, tumours and cysts. The 3D reconstructed images can serve as an excellent patient education tool.

Caries Diagnostics

Dental caries has been traditionally detected at the cavitation stage. Caries diagnostics classically meant examining the tooth and its softness at the base of the cavity resulting in operative management. The advent of non-invasive techniques including DIAGNOdent, Quantitative Light-induced Fluorescence (QLF), fibre-optic transillumination (FOTI), optical coherence tomography (OCT) and electronic caries monitor (ECM). These have created awareness among dentists regarding the importance of detecting non-cavitated lesions. Early detection will help in preservation of the tooth structure and its preventive management techniques.

Bioactive Dentistry

The introduction of smart materials has enhanced the restorative dentistry arena making remineralization a reality. Success with biomimetic materials and progress in tissue reconstruction with stem cells has opened new doors to restoration, replacement and repair of tooth loss structure. This will enable patients to sustain a healthy dentition throughout their lives.

CAD/CAM

In spite of undergoing for preventive and restorative measures, there will a tooth that needs to be replaced with a crown or bridge. Currently, computer-assisted design/ computer assisted manufacture (CAD/CAM) is employed to mill a tooth from a 3-D scan.

3-D Printing

3-D printing is the next big thing and it is being employed in dentistry to replace crowns, bridges and dental veneers. It is even possible to incorporate tooth decay-fighting chemicals into 3-D printed teeth. Other forms of bio-printing include building a jawbone lost due to periodontal disease and tumours.

Conscious Sedation

Anxiety control is an integral part of dentistry. Due to safety factor and effectiveness, conscious sedation using nitrous oxide is being utilized by more dentists. The patient remains conscious and is able to respond to verbal commands. So, needles are not required to calm down anxious and pediatric patients.

Dental Loupes

The magnification provided by dental loupes has made it possible to work with high visual performance.

Single Visit Root Canal Treatment

Endomotors, electronic apex locators and rotary endodontic files have made single sitting root canal treatments which are easily available to patients, eliminate their long and repeated appointments.

Laser Dentistry

The advent of lasers into dentistry has provided bloodless surgical procedures with minimized post-operative inflammation and almost painless healing period. Currently, lasers are replacing conventional, high-speed drills to treat tooth decay painlessly, gingival and periodontal disease, teeth whitening and surgical biopsies.

Invisalign

Invisalign consists of a series of clear, practically invisible customized removable aligners that gently straighten the misaligned teeth without undergoing the discomfort of wearing heavy metal braces. Patients will no longer have a metallic smile with diet restrictions.

Implants & Osseointegration Monitor

Implants are screw retained prosthetic replacements for missing teeth with the strength and feel of a natural tooth. Advancements in implant technology have led to improved treatment outcomes in recent times. Nowadays devices are available to precisely monitor osseointegration which makes it possible to view and store the measurements.

ZOOM! Whitening

Zoom! Whitening is a new state of the art whitening treatment that gives fast and easy results in one appointment. The latest treatment will make your teeth up to eight shades whiter.

Nanotechnology

Nanotechnology is yet another highly researched area which can haul oral health care to unprecedented heights. Nanoparticles can be utilized for tissue engineering, local drug delivery systems, prosthesis, implants, restorative dentistry, dental nanorobots for local anaesthesia. Oral fluid nanosensor test (OFNASET) and oral cancer diagnostics are few of the applications.

Oral Cancer Screening

The major goal of oral cancer screening is early detection to provide a greater chance of cure. Early detection of malignant disorders is made possible by recent advancements in screening of oral premalignant lesions that too, at the molecular level. VELscope is a simple process for the enhanced visualization of oral mucosal abnormalities including potentially malignant disorders and cancer. ViziLite is a painless screening tool for detection of small changes in oral mucosa and monitors abnormalities in patients at an increased risk for oral cancer. Other methods include spectroscopy, optical coherence tomography, immunohistochemistry etc.

A Peek into the Future?

It may not be wrong to anticipate technological advances that will allow patients to scan their own teeth in the comfort zone of their homes using their smart phones. This data can be analyzed and shared with the dentist to schedule an appointment for the appropriate procedure. It’s just a matter of time when all this will be possible.

The constant demand for new innovative solutions to dental care has helped in the advancement and evolution of dental research to best suit patient needs. The future of dentistry looks very different than present practice: no noisy drills, no painful injections, self-healing teeth, easier access and shorter treatment appointments. There will be greater emphasis on prevention leading to fewer diseased states. On an endnote, technological improvement has simplified dental practice with less invasive treatment options for patients. It is definitely transforming dentistry for the better.

Trauma and nerve damage to teeth (Part II)

Trauma and nerve damage to teeth (part 2)Trauma and nerve damage to teeth (part 2)

TRAUMATIC INJURIES OF TEETH

CONCUSSION

  • Concussion refers to vascular structures at the tooth apex and periodontal ligament resulting in inflammatory edema
  • No displacement, only minimal loosening of tooth occurs
  • May result in mild avulsion of the tooth from its socket causing occlusal surface to make premature contact with an opposing tooth

Clinical features

  • Tenderness on gentle horizontal or vertical percussion
  • Tooth sensitive to biting forces
  • Patients usually try to modify occlusion to avoid traumatized tooth

Management

  • Soft diet
  • Relief of occlusal interferences
  • Flexible splinting
  • Periodic monitoring with repeated vitality testing and radiographs

Prognosis

  • Pulp necrosis
  • Root resorption is very rare

LUXATION

  • Dislocation of the tooth from its socket after severing of the periodontal attachment
  • Usually two or more teeth involved
  • Teeth mostly affected: deciduous and permanent maxillary incisors
  • Mandibular teeth seldom affected
  • Vitality testing: temporarily decreased or undetectable
  • Vitality may return after weeks or several months
  • Depending on magnitude and direction of traumatic force
  • Subluxation
  • Extrusive luxation
  • Lateral luxation
  • Intrusive luxation

SUBLUXATION

Subluxation denotes an injury to supporting structures of the tooth that results in abnormal loosening of the tooth without frank dislocation.

Clinical features

  • Teeth are in normal location or limited elevation of tooth from its socket
  • Abnormally mobile
  • Extravasated blood emanating from gingival crevice depicts PDL damage
  • Tenderness to percussion and masticatory forces

EXTRUSION

  • Partial displacement of a tooth out of its socket
  • Often found in deciduous teeth

Clinical features:

  • Tooth appears elongated
  • Usually displaced palatally
  • Bleeding from gingival sulcus
  • Mobile

LATERAL LUXATION

Movement of tooth in a direction other than intrusive or extrusive displacement

Clinical features

  • Comminution or crushing of alveolar process accompany tooth dislocation
  • Movement direction depends on:
  • Orientation and magnitude of the force
  • Root shape
  • Tooth may be pushed through buccal or less commonly lingual cortical plate
  • Root apex palpable insulcus area

Management (Subluxation, Extrusion, Lateral luxation)

  • Restoring teeth to normal position by digital pressure under LA
  • Comminuted pieces of alveolar bone to be repositioned by digital pressure
  • Removal of occlusal interferences if necessary
  • Immobilization for 2-3 weeks using flexible splints
  • Root canal therapy prior to splint removal
  • Extraction of the traumatized teeth should be the last resort
  • Periodic follow up clinically and radiographically

Prognosis

  • Pulp necrosis: Open apex -9%, Closed apex -55%
  • Chances of surface resorption
  • Inflammatory resorption can be seen in association with pulp necrosis
  • Due to compression to the PDL, both inflammatory and replacement resorption may occur

INTRUSION

  • Displacement of tooth into alveolar process
  • Comminution or crushing of alveolar process accompany tooth dislocation
  • Often seen with deciduous dentition, less in permanent dentition

Clinical features

  • Reduced height of clinical crown
  • Gingival bleeding evident
  • High metallic sound on percussion
  • Maxillary incisors may be intruded into the alveolar process
  • Damage to adjacent teeth especially underlying permanent teeth

Management for intrusion:

Depends entirely upon the stage of root development

Immature root formation

  • Spontaneous eruption can be anticipated
  • Luxation of tooth slightly with the forceps done if no signs of re-eruption after 10 days
  • Pulpal healing is monitored during the period of re-eruption at 3, 4, 6 weeks after injury
  • In case of negative response of the pulp or periapical radiolucency
  • Endodontic therapy with calcium hydroxide dressing is done

Completed root development

  • Spontaneous re-eruption is unpredictable
  • Orthodontic extrusion is indicated over a period of 2-3 weeks
  • Prophylactic endodontic therapy is indicated as frequency of pulp necrosis

Prognosis

  • Pulpal necrosis-Open apex-63%, Closed apex –100%
  • External surface, inflammatory and replacement resorption are very frequent findings, especially in teeth with complete root development
  • Severe complication can be seen as late as 5-10 years after trauma

AVULSION

  • Complete displacement of a tooth from the alveolar process
  • Can occur due to direct or indirect trauma 

Clinical features

  • Seen in relatively younger age group
  • Maxillary central incisors-most commonly avulsed teeth in both dentitions
  • Affects single tooth mostly
  • Socket is found empty or filled with coagulum
  • Lip laceration
  • Fracture of alveolar process may occur 

Management

  • If avulsed tooth is not found clinically or radiologically, chest or abdominal radiograph to locate it
  • Reimplantation of permanent teeth. The prognosis depends on:
  • Condition of tooth
  • Time out of socket
  • Viability of residual PDL fibres
  • Splinting
  • Endodontic therapy after reimplantation
  • Follow up

Trauma and nerve damage to teeth (Part I)

Trauma and nerve damage to teeth (Part 1)Trauma and nerve damage to teeth (Part 1)

There are different types of injuries which may vary from minor damage of teeth to grossly comminuted fractures of the skull. Teeth and facial injuries are common among them. National Trauma Databank of American College of Surgeons reported 7,22,824 incidents of trauma in 2010. Falls contributed to major mechanism of injury (38.4%), followed by motor vehicle collisions (28.9%). Injuries from mechanisms of being struck (7.5%), pierced (4.7%) or related to firearms (4.5%) were less common. Head and face injuries accounted for 59.7%. Hence, head and neck trauma are major injuries in the United States.

National Crime Records Bureau (NCRB) is the principal nodal agency, that is solely responsible for the collection, compilation, analysis and dissemination of injury-related information. NCRB had reported 27,10,019 accidental deaths; 1,08,506 suicidal deaths and 44,394 violence-related deaths in 2001. Major cause of trauma was suicide (27%) followed by road accidents (20%), violence (11%), burns (9%), poisoning (6%), drowning (6%), domestic violence (2%) and falls (2%). According to the study of Hsiao et al., head and neck injuries had contributed to 60% of the road traffic injury (RTI) death list in India. In 2012, a forensic study was conducted by Pate et al to analyze the incidence, pattern, mechanism and mode of head injury among 21-30 years. Major accidents were road accidents followed by fall from height and railway. The maximum victims of head injuries were males.

Dento alveolar injuries are limited to teeth and supporting structures of the alveolus. 7-15 years of boys are mostly affected as compared to girls. Maxillary central incisor (80%) is the most commonly affected tooth followed by maxillary lateral incisor, mandibular central incisor and mandibular lateral incisor. The etiology includes road accidents, fall during infancy, sports injuries, domestic violence, iatrogenic causes to permanent tooth bud and inferior alveolar nerve, mental retardation & epileptic seizures, alcohol & drug-related injuries. Direct trauma occurs due to force applied directly to teeth and indirect trauma occurs when indirect force is applied to teeth causing the jaws to strike each other.

A dental injury represents acute transmission of energy to the teeth and supporting structures, which results in fracture and displacement of teeth and separation or crushing injuries. Dental trauma leads to damage to tooth structure, surrounding periodontal ligament, vascular and nerve supply, surrounding bone. This damage is related to the extent of displacement from original anatomic positions.

CLASSIFICATION

There are different types of dental injuries based on the classification suggested by Ellis and Davey in 1970:-

  1. Class I – Fracture involving enamel
  2. Class II – Fracture involving enamel & dentin
  3. Class III – Fracture involving enamel, dentin & pulp
  4. Class IV – Teeth that lost their vitality with or without loss of crown
  5. Class V – Traumatically avulsed tooth
  6. Class VI – Fracture of root with or without crown fracture
  7. Class VII – Displacement of tooth without crown/root fracture
  8. Class VIII – Cervical crown fracture
  9. Class IX – Fracture of deciduous teeth

According to Andreasen, dental injuries can be divided into:

  1. Fractures of the teeth
    1. Coronal Fractures
    2. Root Fracture
      • Without coronal fracture
      • With coronal fracture
  2. Luxation injuries to the teeth
    1. Concussion
    2. Subluxation
    3. Intrusive luxation
    4. Extrusive luxation
    5. Lateral luxation
    6. Avulsion
  3. Fractures of the alveolar bone
    1. Fractures of socket
    2. Fractures of alveolar process
    3. Fracture of associated jaw
  4. Other injuries
    1. Displacement of a tooth which may become dilacerated
    2. Soft tissue injuries such as:
      • Laceration
      • Imbedding of a foreign body
      • Latrogenic injuries such as:
      • Injuries sustained during extractions, including damage to adjacent teeth and fracture of alveolar bone
      • Perforation of tooth apex or side of the root during conservative or endodontic treatment
    3. Swallowing or inhaling of an avulsed tooth

TYPES OF TOOTH FRACTURES

Dental crown fractures contribute to 25% permanent teeth and 40% deciduous teeth injuries. Dental root fractures comprise 7% permanent teeth injuries and 3% to deciduous teeth injuries. Vertical root fractures are mostly found in 5% of total crown-root fractures.

DENTAL CROWN FRACTURES

      • Most commonly involve anterior teeth

Fractures involving crown fall into three categories:

      • Enamel without loss of substance, infraction of crown or cracks
      • Enamel and dentin with loss of tooth substance but without pulpal involvement.
      • Enamel, dentin and pulp with loss of tooth substance and exposure of pulp.

INFRACTION

      • Defined as microcrack in the thickness of the enamel
      • Quite common but not readily detectable
      • Illuminating crowns with indirect light causes cracks

Management

      • Routine vitality testing
      • Sealing of cracks with adhesive systems

UNCOMPLICATED

      • More common than complicated
      • Usually occur at mesioincisal or distoincisal corners of maxillary central incisors
      • Exposed dentin sensitivity to thermal, chemical and mechanical stimuli
      • Deep, pink blush of pulp may be appreciated through the thin remaining dentin wall

Management

      • Composite build up
      • Coronal fragment reattachment

COMPLICATED

      • Bleeding from exposed pulp
      • Exposed pulp is sensitive to stimulation
      • Pulp testing is positive unless there is concomitant luxation injury
      • Depending on the absence or presence of a concomitant luxation injury the pulp will present with bright red, cyanotic or ischemic appearance

Management

DENTAL ROOT FRACTURES

      • Maxillary central incisors most commonly affected
      • Coronal fragments are displaced lingually and slightly extruded
      • Degree of mobility of crown i.e. fracture plane to the apex, more stable is the tooth
      • Root may occur in association with alveolar process fractures
      • Temporary loss of sensitivity is seen which returns back to normal within 6 months

Management

      • More apical and better than prognosis
      • Middle and apical, reduction to position and immobilization
      • Endodontic therapy when evidence of pulpal necrosis
      • Coronal 3rd , Extraction

VERTICAL ROOT FRACTURES

      • Fracture line is parallel to the long axis of the tooth and can extend from crown to the apex
      • May or may not involve the pulp chamber
      • Seen most often in mandibular molars

Clinical features

      • Low level dull pain-cracked tooth syndrome
      • Bite test: Pain on release of biting force
      • Transillumination
      • Staining with disclosing dye
      • Definitive diagnosis is made only on surgical exploration

Management

      • Single-rooted teeth: extraction
      • Multirooted teeth: Hemisection with endodontic therapy and crown

COMBINATION CROWN AND ROOT

      • Involve both crown and root
      • Usually involves pulp
      • Permanent teeth are more affected than deciduous teeth
      • Seen often in anterior teeth due to direct trauma

Clinical features

      • Anterior tooth: plane extends obliquely from the mid portion of the crown facially and extends below the gingival level palatable.
      • Displacement of segments are minimal
      • Bleeding from pulp
      • Pain on mastication

Management

      • Removal of coronal fragment permits evaluation of extent
      • If pulp is not exposed: conservative treatment (Bonding tooth fragment or composite build up)
      • If small amount of root is lost with pulp exposure: crown lengthening + Endodontic therapy
      • If > 3-4 mm of clinical root is lost: removal of residual root

3 reasons why you are exhausted at the end of a workday

3 reasons why you are exhausted at the end of a workday3 reasons why you are exhausted at the end of a workday

Many people love to start a day with confidence and full of energy whereas at the end of the day they feel completely exhausted. Individuals with leadership accomplishment usually walk out of the door at the end of a work day.

The mechanism of thought response as a human doing rather than being a human being:

When you are occupied with multiple things like managing a family, working in an office as a boss and employee makes for a stressful environment that causes fatigue. The prime focus has to be toward maintaining the being state, but most of the time individuals have been trained in the mode of doing state. If you contemplate in your busy days, you have to ask yourself some empowering questions in order to awaken your hidden potential. When was the last time you embraced your leadership quality? When was the last time you embraced your team members? When was the last time you took 15 minutes in the morning to set mindful intentions for the day? When was the last moment you took few minutes to contemplate and celebrate your list of completed assignments? When was the last time you took time to feel your emotions? Ask yourself all these questions and make a drastic difference in your day.

The power of asking questions where the focus and energy are flowing enormously helps us to uplift ourselves to next level. It is always better to aim for a goal that helps an individual to handle all the circumstances easily without feeling taxed.

 Failure in maintaining daily account in an appropriate way

 Everyday experience makes us feed or drains our energy. At the end of the day when an individual feels exhausted,  it could be an indication that person is drained negatively. The negativity will affect the mind and body in an adverse way.

There is a lot of research done that reveals how negativity impacts an individual’s life. When an individual is exhausted, they lack enthusiasm, motivation, etc.; and the words they speak to self-so-called self-talk also seem to be negative. It is always better to overcome the exhaustion by taking a strong decision to find a way to overcome as soon as possible. First and foremost we need to maintain an account of what and which activities positively or negatively affects our energy to help us plan for a better day.

There are certain ideas that can be incorporated in order to feed with the positive sign of creating elevated energy. The positive energy will make the individual focus on task with vitality. The conscious effort by which individual spends in order to gain the energy plays a vital role in regaining their strength.

Certain examples, such as taking a break for 10 minutes in between work, taking a power nap are examples which can feed positive energy and maintain energy levels in the body throughout the day.

Being unaware of what is important and why it matters to you
