Clinical evaluation of compomer in primary teeth: 1-year results

Article Abstract:

Compomer appears to be as effective as hybrid composite resins as a filling material for dental cavities. Amalgam has been the filling of choice for decades, but consumer fears about mercury in fillings has prompted dentists to develop substitutes. One such substitute, Dyract compomer, was tested against Prisma hybrid composite resin in 36 children who each had two cavities requiring a filling. One was filled with the compomer and the other with hybrid composite resin. Both materials were equally effective although the compomer tended to wear faster.

Contraction stress of flowable composite materials and their efficacy as stress-relieving layers

Article Abstract:

Flowable resin-based composites probably will not reduce the stress produced when the filling polymerizes, according to researchers who tested four flowable and six non-flowable composite materials in a tensiometer. Flowable composites contain less filler and have a lower viscosity than non-flowable composites. Despite this feature, the flowable composites produced as much stress as the non-flowable composites.
