Tooth whitening

  1. 1. TOOTH WHITENING/BRIGHTENING PROCEDURES The lightening of the color of a tooth through the application of a chemical agent to oxidize the organic pigmentation in the tooth is referred to as bleaching.
  2. 2. Degradation of high molecular weight complex organic molecules that reflect specific wave length of light responsible for the color of the stain into lower molecular weight and less complex molecules that reflect less light is called lightning. Bleaching is used as sole treatment of choice or in conjunction with other treatment modalities to brighten a whole smile.
  3. 3. HISTORY Bleaching was unsuccessfully used in the middle ages Modern bleaching technique began in 1918.Abbot used the combination of superoxol and heat. 1958—Prarson—intra pulpal bleach 1967--Nutting and Por—walking bleach
  4. 4. 1978—superoxol +heat + light 1989—Haywood .& Hayman (night guard vital bleaching,10% carbimide peroxide) 1996—laser tooth whitening officially started with the approval of ion laser technology Argon and CO2 lasers to be used with a potential system of chemicals
  5. 5. BLEACHING MATERIALS Oxidizing agents Hydrogen peroxide bleaching solution and gels. Ph : highly acidic Conc 3-3.5% Carbamide peroxide based bleaching agents also called Urea hydrogen peroxide, Carbamyl peroxide, Perhydrol urea Conc : 3-45% Ph :5-6.5
  6. 6. HOW WOULD YOUR PATIENTS LIKE THEIR SMILE ? A SMILE CONNECTS
  7. 7. More and more people would like lighter teeth. Not surprising –as nothing can improve a smile like bright white teeth
  8. 8. IN OFFICE VITAL TOOTH BLEACHING Vital tooth bleaching is one of the least invasive, most conservative and most effective procedure to dramatically improve the esthetic appearance of patient smile and selfconfidence.
  9. 9. Indications Light enamel discolorations Mild tetracycline discolorations Endemic fluorosis discolorations Age related discolorations
  10. 10. Contraindications Severe dark discoloration Severe enamel loss Hypersensitive teeth Presence of caries Large/poor coronal restoration
  11. 11. Procedural steps Familiarize the patient with – Probable cause of discoloration – Procedure to be followed – Expected out come – Possibility of future re-discoloration Take radiographs – Detect all carious lesions – Defective restorations and proximity of pulp horns
  12. 12. Evaluate tooth color – With shade guide – Take clinical photographs before and through out treatment.
  13. 13. Apply a protective cream to the surrounding gingival tissues and isolate the tooth with a rubber dam and waxed dental floss ligature. Do not inject local anesthetic.
  14. 14. APPLICATION OF 30% CARBAMIDE PEROXIDE ON THE TOOTH SURFACE MATERIAL IS ALLOWED TO STAY FOR 15-20 MINUTES
  15. 15. PRE AND POST OPERATIVE BEFORE AFTER BEFORE AFTER
  16. 16. NIGHT GUARD BLEACHING/ HOME BLEACHING TECHENIQUE Introduced by Haywood and Haymann in 1989 Dentist prescribed home bleach technique. Bleaching tray ,/ material prepared and dispensed along with follow up appointment for check up.
  17. 17. MATERIALS USED
  18. 18. Tray :step by step Alginate impression of the arch to be taken. Model prepared Block resin applied on the labial surface of the teeth to be bleached to form a small reservoir for the bleaching agent.
  19. 19. BIOSTAR MODEL AND TRAY MATERIAL IN POSITION MOULDED TRAY BLEACHING TRAY MATRIX
  20. 20. FLOSSING BRUSHING APPLICATION OF BLEACHING MATERIAL INSERTION STORAGE
  21. 21. Familiarize the patient with the use of bleaching agent and wearing the guard, instruct the patient that this procedure should be performed 3-4 hours per day or over night. Recall the patient every 2 weeks to monitor stain lightening.10% carbamide peroxide is used for this technique ,this can be later increased to 16%,or up to 20% as per the case reqirements.
  22. 22. BEFORE AFTER BEFORE AFTER
  23. 23. Vivastyle paint on THE PROFESSIONAL VARNISH SYSTEM FOR WHITENING TEETH
  24. 24. Why use a varnish system ? Vivastyle paint on is insoluable in water. Consequently, the varnish is not prematurely washed off the teeth by saliva. Vivastyle paint on contains 6% carbamide peroxide when applied. This component releases oxygen , which gently lightens stains. Once it has dried, its concentration is about five times higher.
  25. 25. STEPS OF APPLICATION Available as standing tube with brush and dispensing dish for single use
  26. 26. Brushing and flossing of teeth before application of varnish
  27. 27. DRYING WITH BLOTTING PAPER APPLYING PROTECTIVE GEL
  28. 28. Vivastyle paint on is applied directly to the teeth with a brush and allowed to dry for 30 seconds
  29. 29. The dried varnish remains on the teeth for 20 minutes and is subsequently removed with a toothbrush.
  30. 30. APPLICATION OPTIONS Once daily for 20 min. over a period of 14 days. Twice daily for 20 min. over a period of 7 days
  31. 31. CLINICAL RESULTS -Noticeable whitening of teeth after just a few days -Less irritation
  32. 32. Significant whitening of teeth after treatment with Vivastyle Paint on
  33. 33. Advantages professional tooth whitening without a tray, as – Patients find tray application uncomfortable – Patients are looking for a more cost-effective alternative smooth integration into daily schedule gentle application touching up of previously whitened teeth
  34. 34. NON VITAL BLEACHING Intra coronal bleaching of Endodontically treated tooth
  35. 35. Technique Radiographically assess the status of the periapical tissues and the quality of endodontic obturation.Endodontic failures or questionable obturation ,should always be retreated prior to bleaching.
  36. 36. Evaluate tooth color with a shade guide and take a clinical photograph
  37. 37. Isolate the tooth All restorative material from the access cavity removed to expose dentin and refine the access.
  38. 38. Cavit and GIC base at least 2 mm thick to cover the endodontic obturation.
  39. 39. Pack the pulp chamber with 30% carbamide peroxide Seal the access with IRM at least 3mm for a good seal. Recall after 2 weeks. Instruct the patient
  40. 40. PRE AND POST OPERATIVE
  41. 41. Diamonds are forever, Skyce is just for cosmetics.
  42. 42. MEDICAL EXPERTISE ON COSMETIC PROCEDURES Dentists of today are finding that more and more people who consult them are no longer really patients. They are individuals who desire perfectly aligned, sparking white teeth, and who may even ask for tooth jewellery.

Vivadent has developed the skyce system of tooth jewellery, which enables dentists to satisfy this cosmetic demand according to dental requirements.
  43. 43. STUNNING JEWELLERY ON HEALTHY TEETH Patients want a sparking smile and dentists want teeth to be healthy. Dentists are committed to maintaining the health of teeth at all costs. The dental jewellery is bonded onto the tooth in the same way as an orthodontic bracket.
  44. 44. SLIGHT ETCHING; STRONG BOND Retentive pattern is produced on the enamel using 37% phosphoric acid.
  45. 45. Placement of flowable composite, the right consistency
  46. 46. Lifting the skyce using a probe tip with bonding agent
  47. 47. Skyce bonded to the tooth with flowable composite
  48. 48. Skyce Flowable Composite Tooth Skyce is bonded to the tooth with the transparent Flowable composite Skyce must be encircled by a little Flowable composite to ensure micromechanical retention.
  49. 49. TWO COLOURS; TWO SIZES Skyce is made of crystal glass. It is available in two different colours and sizes: “crystal” and sapphire blue”, 1.8 mm or 2.5 mm in diameter.
