About

The maintenance of the deciduous tooth until its physiological exfoliation occurs is one of the main objectives of pediatric dentistry. Endodontic treatment in deciduous teeth resulting from carious or traumatic lesions with pulpal involvement is often necessary and we often find it difficult to perform it, due to the difficult control of the child, the internal anatomy of the root canals, and root resorptions. The non-instrumental endodontic treatment technique (TENI) associated with antimicrobial drugs has advantages such as shorter chair time and less complexity than the conventional technique in which root canal instrumentation is performed. The objective of this study is to carry out a controlled and randomized clinical trial to compare the effectiveness of non-instrumental endodontic treatment (NIET) in primary teeth associated with the use of two filling pastes. 120 necrotic deciduous teeth of children aged between 3 and 6 years will be selected; and the teeth will be divided into two groups. In Group 1 and Group 2, the root canals will not be instrumented, just irrigated and filled with the respective pastes, CTZ and Guedes-Pinto. The radiographic aspects will be evaluated, considering the repair process, clinically will be evaluated: presence of fistula and mobility, the evaluations will be carried out in both groups on the day of treatment and in periods of 1, 3 and 6 months after treatment. The data obtained will be submitted to the Shapiro-Wilk normality test, where the statistical analysis that will be used for this study will be defined, adopting a significance level of 95% (p<0.05).
