Clinical Evaluation of Restoration of Grossly Carious Primary Teeth Using Biological Approach

To widen the treatment option of primary teeth with mutilated crown tooth structure but having more than two-thirds of root structure were restored by using natural tooth crowns with the help of adhesive materials.

To restore the grossly decayed primary molars with biological crowns and to evaluate them for longevity, change in color, occlusal wear, marginal integrity, and patient/parent acceptance.

Twenty primary molars from 6 to 10 years old children were restored with biological crowns (extracted/exfoliated tooth crowns) and follow-up was done till 12 months. Data tabulated and results were statistically analyzed using Kaplan-Meier survival analysis. The statistical software SPSS 19.0 was used.

89.47% of biological restorations survived successfully till 12 months follow-up period. No occlusal wear was found in any of the samples, a breach in marginal integrity was seen only in 16.6% of cases, and only 5.5% of biological crowns showed discoloration (darker) at 12 months intervals. 65.00% of patients well accepted the treatment and showed satisfaction while 20.0% of patients remained neutral. Only 15% of patients experienced dissatisfaction at the end of the study.

Biological restorations proved to be a viable alternative for the restoration of grossly mutilated primary molars.
