Abstract
Objective To study the application of the strip crowns in restoration of multi-surface caries decay in primary anterior teeth.Methods Seventy-two patients with 174 multi-surface caries of primary anterior teeth were divided into group A(control group,86 cases),group B(experimental group,88 cases).Teeth were restored with composite resin in group A and strip crowns in group B,respectively.6 months after therapy,restorations were re-examined at 6-month and 18-month follow-up.Results 6-month retention rate was 96.51% for group A and 100% for group B,with no significant difference between two groups.18-month retention rate was 67.44% for group A and 100% for group B,with significant difference(P0.01) between two groups.Conclusion Strip crowns is a convenient and effective method to restore the multi-surface caries of primary anterior teeth.
