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.

7. 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.

8. HISTORY
Bleaching was unsuccessfully used in the
middle ages
Modern bleaching technique began in
1918.Abbot used the combination of
superoxol and heat.

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

10. BLEACHING MATERIALS

Hydrogen peroxide bleaching solution and gels.
Ph : highly acidic
Conc 3-3.5%
Carbamide peroxide based bleaching agents

cream to the
surrounding gingival
tissues and isolate
the tooth with a
rubber dam and
waxed dental floss
ligature.
Do not inject local
anesthetic.

17. APPLICATION OF 30%
CARBAMIDE PEROXIDE ON
THE TOOTH SURFACE
MATERIAL IS ALLOWED TO
STAY FOR 15-20 MINUTES

19. Significant whitening of teeth after treatment with Vivastyle Paint on

20. 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

21. 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.
