Abstract:
The widespread use of aesthetic fillings has
highlighted their advantages and disadvantages. One
of the most troublesome features of earlier aesthetic
materials was the difficulty of finishing the restoration
surface to decrease adherence of food debris. The
rougher the finished surface, the greater the possibility
of bacterial accumulation and discolouration of
restoration along the restoration margin with secondary
caries formation. Aside from these clinical
implications, patients are highly discerning and could
detect roughness of 0.30 μm with their tongue. The
aesthetic restoration should mimic the appearance of
natural dentition and should have an enamel-like
appearance. An increased demand for superior
aesthetics from composite resin has increased the
demand for more eff icient and simple polishing
techniques. The development of nanocomposites has
given a new perspective to the polishing of composite
resins. Nanocomposites claim the advantage of
improved gloss, optical characteristics and reduced
wear. To date, results of in vitro studies have been
equivocal regarding the most efficient and effective
polishing system. There is variation in the effects of
different finishing and polishing instruments on the
surface roughness due to great diversity in size, shape,
composition and distribution of the filler particles of
composite resins, type of resin and a wide variety of
finishing and polishing instruments. This paper will
review the different factors that affect polishing
techniques used in achieving the desired polish on
composite resin restorations.
