[A proposed clinical method for the finishing of composite-resin restorations by means of diamond burs and abrasive disks and strips: a SEM analysis].
BACKGROUND
Composite resin is the most cosmetic material used in restorative dentistry. Its functional and cosmetic features are enhanced by an appropriate finishing. A non finishing surface is very rough, allowing therefore plaque accumulation and pigments deposition deriving from feeding.


METHODS
In this study the authors performed several finishing methods using diamond burs, abrasive disks and abrasive strips. All the samples were analyzed by means of SEM at 100x, 300x and 500x.


CONCLUSIONS
The results showed several differences among tested samples according to the material and the technique used. Satisfactory finishing is performed by the association of medium and fine sizes finishing burs (Intensiv 50/D4 and Intensiv 40/D4) and medium and fine abrasive disks (Sof Lex Pop On 3M 1981 M and F), or by medium and fine finishing abrasive burs and abrasive strips (Sof Lex 3M Coarse-Medium/Aluminum Oxide N. 1954-150 and Fine-Superfine N. 1956-120).
