Objective:
To evaluate the clinical effects of gingival composite resin used for restoring cervical defects in anterior teeth.
Methods:
Eighty cervical defects of anterior teeth were involved. Firstly, they were restored with simulated restorations using only tooth colored composite resin. Then, the simulated restorations were removed and the defects were restored with simulated restorations using gingival composite resin combined with tooth colored composite resin. Visual analogue scale (VAS) was employed to survey the patient satisfaction with the esthetic results of the two methods. The defects were filled with gingival composite resin and tooth colored composite resin.Then, longitudinal clinical evaluation were made at 1-week, 6-month, 1-year and 2-year recalls respectively using modified United States Public Health Service (USPHS) criteria.
Results:
Simulated restorations made of gingival composite resin and tooth colored composite resin obtained more satisfaction in overall impression, gingival position and tooth contour than simulated restorations simply made of tooth colored composite resin (P<0.1). In the longitudinal clinical evaluation, no significant differences among the recalls were found in color match,restoration morphology, marginal adaptation, marginal discoloration, secondary caries or pulp sensitivity (P>0.1).
Conclusion:
Using gingival composite resin in restoring cervical defects in anterior teeth achieved not only satisfactory treatment effect but also ideal esthetic results.
