Primary Outcome Measures

Name	Time	Method
During the course of this clinical study, we hope that the results promote reduction of microorganisms after the application of antimicrobial photodynamic therapy. This will be analyzed through a careful microbiological analysis of the dentin collected at three different moments for the teeth that will be submitted to the photodynamic therapy: before the selective removal, after the selective removal and after the application of antimicrobial photodynamic therapy, while for the teeth that will not receive the application of antimicrobial photodynamic therapy, this collection of dentin will be performed in two periods only: before the selective removal and after the selective removal. The collected dentin will undergo a serial dilution process and will be inoculated in plates with SB20 culture medium for the growth of Streptococcus mutans. Plates will be incubated in 10% CO2 at 37 ° C for 48 hours. The colony forming units (CFUs) will be counted, and the results will be expressed in CFU / mg remaining dentin.
