COMPOSITE RESIN (LIGHT CURE FILLING)
In modern dentistry, for teeth fillings, Composite Resin is preferred as it has sufficient strength, is available in the colour of the teeth and is easy to use. It has excellent finishing & polishing & various shades are available making it look very natural. Disadvantages are its technique sensitivity, tendency to discolor over long period of time. If not done properly, can result in post filling sensitivity.
Amalgam has been widely used for direct fillings, mainly for posterior teeth, but because of certain disadvantages like its metallic color, taste, leaching out of mercury, tendency to shrink & corrode, the tooth has unaesthetic appearance. Hence it is less preferred by the patients & dentists.
