Summary
The aim of the proposed study is to assess the clinical effect of photodynamic therapy
(PDT)using LED on dentin with carious lesions in permanent teeth. Patients with molars
exhibiting deep carious lesions on the occlusal surface indicated for restorative treatment
will be randomly allocated to two groups: Group 1 -Control after incomplete caries
removal,indirect pulp treatment with calcium hydroxide(CH); Group 2 - PDT + CH after
incomplete caries removal,disinfect the residual dentin with PDT(LED + methylene),then
indirect pulp treatment with CH. Dentin samples will be removed before and after PDT for
microbiological analysis. The microbiological samples will be cultured in Brucella blood
agar, Mitis Salivarius-bacitracin agar and Rogosa Selective Lactobacillus agar. The teeth
will then be restored using resin with clinical and radiographic follow up at six, 12 and 24
months. The data will be submitted to descriptive statistics.
