Clinical Trial Summary

The maintenance of primary teeth until their exfoliation has been one of the main purposes of Pediatric Dentistry, are they representing the fundamental basis for proper occlusion of the permanent dentition. Often, injuries or extensive dental caries reach the pulp of deciduous teeth making maintenance on these dependent endodontic treatment arc. Thus, this study was to conduct a randomized clinical trial is to evaluate the performance of endodontic treatment in primary teeth using MTA paste, comparing to Vitapex.

Description:

After approval by the ethics committee of the patients Faculty of Dentistry, University of São Paulo that having root canal filling of primary teeth will be invited to participate in the study. A clinical examination and prior radiographic diagnosis will be-held. The patient will be randomized to one of two groups and will be made the endodontics by a dentist. The patient will be accompanied with periods of one week, one month and three months by a blinded evaluator. The outcome will be the success or failure of endodontic treatments evaluated through permanent tooth in the arch on clinical and radiographic conditions of normality. The longevity of the treatments will be evaluated by estimating survival rates by Kaplan-Meier. The differences between the survival rates according to the type of proposed endodontic treatment will be analyzed using the log-rank test with a minimum significance level of 5%.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Success or failure of endodontic treatments	The success or failure of endodontic treatments evaluated by the time spent in the tooth arch in clinical conditions of normality, able to maintain or restore the health of periodical tissues after the treatment. Clinical criteria for determining success are: absence of fistula, absence of painful symptoms and pathological absence of adequate mobility and gingival contour. Radiographically, the success criteria are: absence / reduction of periapical bone rarefaction in anterior and absence / bone rarefaction in the furcation area of later, maintaining the periradicular space, root resorption compatible with the eruptive phase and absence of pathological bone resorption. To evaluate the reduction of lesions or appearance of new lesions will be between the initial and follow-up radiographs. Radiographs will be scanned and the end of the bone rarefactions starting area and will be measured on a software image analysis.	3 months
