INTRACORONAL BLEACHING PDF

Intracoronal bleaching of nonvital teeth involves the use of oxidizing agents within the coronal portion of an endodontically treated tooth to remove tooth discoloration American Association of Endodontists It can be successfully carried out even many years after pulp devitalization and discoloration have occurred see Figure 8. The objectives of treatment are to reduce or eliminate discoloration, improve the degree of coronal translucency, and alleviate present and prevent future adverse clinical signs or symptoms American Association of Endodontists The successful outcome depends mainly on the cause, correct diagnosis, case selection, and proper application of bleaching technique Rotstein and Walton There are more choices for nonvital bleaching these days Table 8. This enhances the bleaching action and is much safer.

One explanation given for this phenomenon is that it results from an inflammatory process initiated by the presence of bleaching agents in the attachment apparatus.

The basis for this conclusion is discussed. A review of published case reports on external cervical resorption associated with intracoronal bleaching revealed that: per cent of the affected teeth had no intermediate dental base placed, 84 per cent were treated with a thermocatalytic technique, 80 per cent were bleached after the root canal sealer was fully set and 72 per cent had a history of trauma before bleaching.

Based on these observations, it should be possible to safely bleach teeth intracoronally provided specific concerns and considerations are taken into account. These are: 1 the use of heat should be avoided; 2 an intermediate dental base should be placed with due respect to the attachment level; and 3 a base should be selected with due respect to its effectiveness in sealing tooth structure.

Intracoronal bleaching: concerns and considerations.

Aim: To compare the bleaching efficacy of sodium perborate with different activation methods on crowns discolored by two different antibiotic pastes. Materials and Methods: Eighty-five extracted human incisors were prepared to size 30 using ProTaper rotary instruments. Spectrophotometric readings were obtained on day 0—week 4. Spectrophotometric readings were obtained on days 3—7. Conclusions: Both antibiotic pastes induced crown discoloration that was reversible using all sodium perborate bleaching techniques.

Intracoronal Bleaching of Nonvital Teeth

Aim: The purpose of this in vitro study was to evaluate the ultrastructural changes of dentin induced after exposure to different intracoronal tooth bleaching agents. Materials and Methods: Dental discs of 1 mm thickness were prepared from coronal dentin of sixty-four human maxillary premolars. The specimens were then evaluated under scanning electron microscope to determine diameter of dentinal tubules and chemical analysis. Conclusions: All bleaching agents increased dentinal tubule diameter and promote alterations in mineral content of dentin with the exception of Sodium perborate mixed with water.
