Bleaching primary teeth with 10% carbamide peroxide.

Bleaching teeth with 10% carbamide peroxide in a custom-fitted tray has been popular for more than 10 years. However, primary teeth are seldom considered for bleaching due to the need for compliance by the child and the natural whiteness of the primary teeth. This report describes an indication-teeth darkened from trauma-as well as the technique and outcome for bleaching discolored primary teeth.

Correlation between fissure discoloration, Diagnodent measurements, and caries depth: an in vitro study.

PURPOSE: This in vitro study was performed to correlate the presence of discoloration on occlusal surfaces with its histological depth and assess its influence on Diagnodent measurements in a group of permanent and primary teeth. METHODS: Ninty-five primary and 95 permanent third molars were randomly selected from a pool of macroscopically intact teeth. One site of the fissure on each occlusal surface was selected and categorized according to its discoloration. Each site was measured 3 times with Diagnodent. The teeth were prepared histologically and evaluated according to their caries extent under a microscope (final magnification x 12.8). RESULTS: In the group of permanent teeth with dark brown or black discoloration (N=23), 13% showed dentinal caries, 57% were sound or had an initial enamel lesion, and 30% had a deep enamel lesion. In the group of primary teeth with dark brown and black discoloration (N=19), 42% presented dentinal caries, 42% showed deep enamel caries, and 16% had an initial enamel lesion. The difference between permanent and primary teeth was statistically significant (P<.05). Discolored fissures showed higher Diagnodent values than nondiscolored or opaque fissures in both groups (independent of their caries status). CONCLUSIONS: The presence of brown or dark spots on fissures were not useful for the prediction of dentinal caries for permanent teeth. In primary teeth, however, a higher correlation between fissure discoloration and dentinal lesions was found. Diagnodent tends to overscore discolored surfaces.

Full veneer versus traditional veneer preparation: a discussion of interproximal extension.

STATEMENT OF PROBLEM: Traditional veneer preparation has come to represent an almost universally accepted guideline of veneer preparation. It calls for an interproximal finish line at or just into the contact point. However, in certain situations, such an approach can have functional and esthetic limitations. PURPOSE: This article reviews those functional and esthetic limitations and discusses an alternative technique, the full veneer preparation. The advantages and disadvantages of this approach are discussed in relation to veneer cases with malaligned teeth, diastema, discoloration, black spaces, restorations, and/or veneers next to crowns.

Procera AllCeram laminates: a clinical report.

The use of Procera AllCeram laminates for patients with discolored teeth has been described. In our experience, these laminates are simple to use and provide possibilities for excellent esthetics.

Unusual case of green teeth resulting from neonatal hyperbilirubinemia.

Despite its rarity, the unusual green pigmentation of a child's teeth causes great anxiety within the family and peer problems of significance for the child. Timely initiation of dental treatment to prevent disintegration of hypoplastic teeth and to offer cosmetic improvement of unusually discolored teeth must be made available to these children, to assure their normal physical, psychological, and social development. The methods, techniques, and materials available today make this possible.
