Survival of adhesive restorations in cavities prepared with two caries removal techniques

[摘要] Objective:Evaluate the survival of adhesive restorations in cavities prepared with partialor total caries removal.Methods:A randomized double-blind clinical trial was conducted. The sample was composedof 107 teeth of 32 children aged 4-8 years who met the inclusion and exclusioncriteria set for the trial. These children had deep cavities that covered oneor two dental surfaces, which were treated by partial or total caries removal.Radiographic and clinical evaluations were performed every six months for twoyears. The children involved in the trial and the adults in charge of them alsoreceived motivation sessions, training, support and oral hygiene devices ona permanent basis. The data obtained were subjected to Kaplan-Meier survivalstatistical analysis, and the Log Rank test was used to determine the differencebetween the treatments. Survival table analysis was performed which includedthe two treatments at 6, 12, 18 and 24 months.Results: No significant difference was found between total and partial caries removaltechniques (p= 0.61). Survival percentages were found to be 95 % at 6months, 88 % at 12 months, 81 % at 18 months and 55 % at 24 months.Conclusions:No significant difference was found between the use of partial and total cariesremoval for cavity preparation. Further studies about restoration survival shouldconsider a 30 % dropout rate.
