About

The goal of this clinical trial is to learn if adjuvant antimicrobial photodynamic therapy (aPDT) can help in the treatment in patients with pieces with apical periodontitis and the presence of fistula, in terms of reducing symptoms, resolution of fistula and the clinical signs of inflammation at the oral mucose, as well as, evaluation radiographic parameters.

Participants will undergo conventional endodontic treatment at Group I (n=15) and will undergo conventional endodontic treatment combined with antimicrobial photodynamic therapy at Group II(n=15).

Full description

The calculation of the sample size was conducted with the statistical software G-Power 3.1 applying the chi-square homogeneity test. Identical sample sizes were considered for the aPDT group and the sham group. The percentage of type error was set at 5% and the statistical power at 80%, obtaining n = 30 considering 10% losses. The distribution of data within each group and the homogeneity of the variants will be verified for the choice of an analysis of variance or not. With this information the most proper statistical test will be conducted. The sample size calculation is based on the literature and a 5% significance level will be adopted
