Dental composite resins (better referred to as "resin-based composites" or simply "filled resins") are dental cements made of synthetic resins. Synthetic resins evolved as restorative materials since they were insoluble, of good tooth-like appearance, insensitive to dehydration, easy to manipulate and inexpensive.
The cost of the restoration is typically cheaper than composite restorations. Disadvantages of amalgam include poor aesthetic qualities due to its colour. Amalgam does not bond to tooth easily, hence it relies on mechanical forms of retention. Examples of this are undercuts, slots/grooves or root canal posts.
Compomers are resin-based materials like dental composites, and the components are largely the same.. The setting reaction is similarly a polymerisation process of resin monomers (e.g. urethane dimethacrylate) which have been modified by polyacid groups, and is induced by free radicals released from a photoinitiator such as camphorquinone.
Inlays are most commonly constructed in composite resin and ceramic materials. Both types have varying properties, however the general downsides to inlays include: Higher cost compared to a restoration, due to the need for a dental laboratory [11] Lengthier process as two appointment required i.e. increased chair time for patient [11]
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
The cost is similar to composite resin. It holds up better than GIC, but not as well as composite resin, and is not recommended for biting surfaces of adult teeth, [22] or when control of moisture cannot be achieved. [23] [24] Generally, RMGICs can achieve a better aesthetic result than conventional GICs, but not as good as pure composites.

The New England Children's Amalgam Trial (NECAT), a randomized controlled trial, yielded results "consistent with previous reports suggesting that the longevity of amalgam is higher than that of resin-based compomer in primary teeth, according to a 2007 review of the study, [22] with some similar claims in a 2003 paper, [30] and composites in ...
