1DENTAL RESTORATION
Introduction:
In the field of dental health, the choice of composite material determines the
restoration of anterior teeth. Each composite have different fill particles and mechanical
properties. The main purpose of paper is critique a study which conducted a five year clinical
evaluation of a nanofilled and a nanohybrid composite in Class IV cavities (1).
Critique of the study:
The main purpose of the study was to evaluate a nanofilled and a nanohybrid composite,
in combination with their manufactured-recommended etch and rinse adhesives in class IV
cavities. As the study was looking for anterior composites, the author specified that small filler
particle is needed to enhance smoothness. The author gave a good description on the mechanical
properties of the selected composite material. For example, the author clearly stated that
nanocomposite is a new group of composite resins and two examples of this type of composite
are nanofillers and nano hybrid. The mechanical property of nanofilled composite is that it uses
nanoparticles throughout the resin matrix, whereas nanohybrids are filled with nanometric
particles as well as conventional fillers. The author gave example of several other nanocomposite
materials that is available in the market. The key highlight of the aesthetic composite system
formulation was that it included vast range of shade options for different layer of teeth as well as
areas of the teeth (1). The main challenge for dentist is to perfectly create a direct composite
restoration. However, this has been challenging because of many material limitation that
influence shade integration and surface quality of the restoration. Hence, the advantage of
nanocomposite material is that it provides the ability to maintain shade integration and
smoothness of the teeth (2).
