Clinical Trial Summary

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).

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

Intervention

Device:
• aPDT
Mechanized endodontic treatment using an endodontic rotatory device (DENTSPLY) will be used to prepare the root canals. Following, it will be applied the methylene blue solution in surfactant medium and after 1 minute a diode laser equipment (DMC THERAPY/EC, Sao Carlos, Brazil) will be used to shine light at a wavelength of 660nm, 100 mW (miliWatts) and irradiation time of 3 min. CaOH (calcium hydroxide) paste will be applied at the root canals canals as a long-term dressing for endodontic treatment..

Procedure:
• Endodontic treatment
Mechanized endodontic treatment using an endodontic rotatory device (DENTSPLY) will be used to prepare the root canals. Following, it will be applied the methylene blue solution in surfactant medium and after 1 minute a diode laser equipment (DMC, THERAPY/EC, Sao Carlos, Brazil) will be used with an aluminium foil at the tip of the equipment to block light and use during 3 min as study group. CaOH (calcium hydroxide) will be applied at the root canals as a long-term dressing for endodontic treatment.
