Stainless Steel Crowns Versus Bulkfill Composite Resin for Restoring Primary Molars After Endodontic Treatment

Dental Caries Clinical Trial

Official title:
Stainless Steel Crowns Versus Bulkfill Composite Resin for Restoring Primary Molars After Endodontic Treatment: Randomized Clinical Trial

Clinical Trial Summary

The pulp therapy in primary teeth is designed to eliminate the infection and keep the tooth in a functional state until its natural exfoliation. An important step for the success of endodontic therapy is the final restoration, which must seal the tooth, avoiding new contamination. Thus, this study proposes to carry out a randomized clinical trial with longitudinal follow-up of two years, in order to compare the degree of success of endodontic treatment in primary teeth restored with two different techniques: composite resin (Filtek Bulk Fill - 3M ESPE) or stainless steel crowns (3M ESPE). Success will be measured by clinical and radiographic features of primary teeth treated with the different restorations after 1, 6, 12 and 24 months. Among the secondary outcomes that will be assessed are the quality and durability of restorations and the cost benefit of treatments. Patients who seek the university clinics and require endodontic treatment will be invited to participate. The sample unit is the tooth and these will be randomized in groups through a randomization list created and distributed in sequential opaque envelopes. The envelope will be opened only after the end of endodontic treatment, to ensure allocation concealment. The data will be statistically analyzed using the Stata 12.0 (Stata Corporation, College Station, TX, USA). The longevity of the treatments will be evaluated by estimating survival rates using the Kaplan-Meier method. Differences between survival rates according to the type of endodontic proposed treatment will be analyzed using the log-rank test. All other clinical variables will be analized using Cox regression. The significance level for all analyzes will be 5%.

Patients who seek the university clinics and require endodontic treatment will be invited to participate. The sample unit is the tooth and these will be randomized in groups through a randomization list created and distributed in sequential opaque envelopes. The envelope will be opened only after the end of endodontic treatment (made with Guedes-Pinto paste), to ensure allocation concealment. The data will be statistically analyzed using the Stata 12.0 (Stata Corporation, College Station, TX, USA). The longevity of the treatments will be evaluated by estimating survival rates using the Kaplan-Meier method.
