Posterior composite resin: use for anterior restorations.

Because of its low filler particle percentage, microfilled composite resins--traditionally recommended for anterior restorations--are extremely translucent. Function, especially in terms of shear-fracture-strength, has been another problem associated with the final restoration. Presented here is the concept of using posterior composite resin as an esthetic restorative material for anterior teeth.

Internal bleaching of discoloured teeth.

Internal bleaching can be a simple, economic and effective method for improving the appearance of discoloured non-vital teeth. The authors give a step-by-step guide to the 'walking bleach' technique, and describe how to avoid the most common potential complications of bleaching.

[Clinical evaluation of two tooth bleaching techniques].

The purpose of this paper was to assess the clinical ability of two bleaching techniques. Patients with at least one darkened teeth caused by mechanical injuries or imperfection in the endodontic therapy were included in this study. The first step was to take an initial photography. After that the teeth were subjected to the bleaching procedures. The techniques employed were proposed by NUTTING & POE or LACERDA et alii. The assessments were made by three trained examiners using the initial and final pictures. The scores were attributed according to the color of the teeth. The data were submitted to the statistical analysis, when was possible to verify that both techniques were equally effective.

[Air polishing instruments. Review of literature].

The popularity of polishing air devices (AP) is rising with the increased distribution of commercial units in both United States and European dental offices and clinics. The instrument's efficiency and effectiveness in stain removal has been demonstrated with minimal impact on soft tissue trauma and abrasion. This article reviews the literature on AP. Future research is indicated to explore surgical clinical applications of airpowder polishing as well as more detailed information regarding the biological basis for its use.

[Bleaching of a vital upper central incisor].

One trauma can elicit tooth vitality loss, even partial. The pulpal tissue necrosis, that is produced, causes darkening of the tooth. We can return this teeth to its original color using the bleaching technique.

Comparison of two commercially available chlorhexidine mouthrinses: I. Staining and antimicrobial effects in vitro.

Several commercially produced chlorhexidine rinses are now available. These formulations vary in concentration and recommended regimens of use. One formulation, a 0.1% chlorhexidine rinse, anecdotally has been reported to not produce the characteristic dental staining. The aim of this study was to compare the 0.1% formulation with a 0.2% commercially produced chlorhexidine rinse for staining and antimicrobial effects in vitro. Tea staining of tooth and acrylic specimens exposed to the two rinses at various dilutions was measured over a 5-day period. Minimum inhibitory dilutions of each product against standard test bacteria were determined by agar dilution. The 0.1% product produced no staining of specimens greater than that noted with controls. At equivalent concentrations, the 0.2% product produced heavy staining of specimens. The antimicrobial effect of the two products was similar but the overall profile for the 0.1% preparation suggested activity derived from ingredients other than chlorhexidine. The results suggest that the chlorhexidine in the 0.1% rinse was partly or completely inactivated and, although staining may not occur in vivo, the formulation would have a much reduced antiplaque action.
