Changes in a light-cured composite resin material used to restore primary anterior teeth: an eighteen month in vivo study

A simple method for treating grossly decayed primary anterior teeth (GDPAT) is of clinical importance since the age of the patient precludes lengthy and difficult procedures. This study assessed the suitability of a light-cured microfilled composite resin material for the repair of GDPAT. The material Durafill was used to restore 81 primary teeth in 24 children (mean age 3.5 y). The restorations were assessed according to predetermined criteria at 6, 12, and 18 months. Results showed a significant deterioration in cavomarginal discoloration and anatomic form (p less than 0.05). Changes in anatomic form were significantly related to marginal adaptation, secondary caries, gingivitis and pain (p less than 0.05). Despite the observed changes, Durafill performed adequately and offers the dentist a simple method for restoring GDPAT.
