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).

Indiana University-Purdue University Indianapolis (IUPUI) / The investigation was undertaken to determine the effects of the polishing and finishing of dental amalgam in relation to its marginal breakdown. The study was also conducted to make a clinical comparison of the marginal integrity of Dispersalloy restorations as compared to Twentieth Century Fine Cut Alloy restorations in both the polished and unpolished state. Forty patients with a total of 131 Class I amalgam restorations were used as the study group. The two alloy systems and polish or unpolish techniques were selected from a random table. Photographic evaluation of the restorations was used to judge the degree of marginal breakdown. The results of the study at the one-year evaluation show two main findings: (1) the Dispersalloy restorations showed less marginal breakdown than the Twentieth Century Fine Cut Alloy restorations, and (2) there was no significant difference between the polished and unpolished restorations overall.
