Eligibility
Age
6 Years to 9 Years
Inclusion criteria
Inclusion criteria: The children analyzed in the study should be aged between 6 and 9 years of both genders and should have at least one lesion of active class I caries in homologous molars. It is necessary that this lesion reaches the dentin being deep or medium. The lesion should cover only the occlusal surface (Class I) considering that the pulp is vital and there is no sealant; amalgam or composite resin restorations in the study tooth.
Exclusion criteria
Exclusion criteria: Children who have teeth changes such as pain; spontaneous sensitivity; fistula; edema; mobility not compatible with stage of rhizolysis and present in the radiographic examination the presence of radiolucency in the region of furca and periápice; increased periodontal space and internal / external dental resorption will not be selected for the study.

| 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. | — |
