Indiana University-Purdue University Indianapolis (IUPUI) / Clinical studies on composite resins in Class II
Resotrations place in adults indicate that wear is the
predominant problem. However, little has been published on
the use of composites for such restorations in primary teeth. The purpose of this study was to compare amalgam to
composite resins in such restorations. Two composite resins
(Adaptic and Radio-opaque Adaptic) served as the
Experiemental material and amalgam, (Dispersalloy) was the control .
One operator placed 57 sets, one restoration of each of
the three materials per set, in 50 patients at the Riley
Children's Hospital in Indianapolis. Evaluations were made
at baseline, six months, one year, two years, and three
years using the Ryge-USPHS criteria and by means of casts
poured from elastomeric impressions.
Results of the Ryge-USPHS criteria indicated no wear or
color change of the composites after two years (p=N.S.).
However, of the 49 sets that returned at one year, two
composites had caries around the restoration. This
particular observation was monitored at the three-year time
interval and found not to increase around any other
composite restorations. Composite restorations in posterior
primary teeth compared equally to amalgam (Dispersalloy) for
the first two years of the project. The loss of anatomic form was significant after three years (p=.05).
