An in Vitro Evaluation of Antimicrobial Photodynamic Therapy on Deciduous Carious Dentin

Dental Caries Clinical Trial

Official title:
A Randomized in Vitro Evaluation of Antimicrobial Photodynamic Therapy on Deciduous Carious Dentin

Clinical Trial Summary

Despite of the decline of dental caries, this disease is still common in polarized groups affecting children. Therefore, the aim of this randomized blind in vivo study was to compare the antimicrobial effect of two antimicrobial therapies in deciduous carious dentin. Thirty two patients aging from 5 to 7 years old had partial caries removal in deep carious dentin lesion in deciduous molar and were divided in three groups: 1. Control - chlorhexidine and resin modified glass ionomer cement (RMGIC); 2. LEDTB - antimicrobial photodynamic therapy (APDT) with LED (light emission diode) associated with toluidine blue orto dye solution and RMGIC; 3. LMB - APDT with laser associated with methylene blue dye solution and RMGIC. The patients were submitted to initial clinical and radiographic examination and demographic features were evaluated by biofilm, gingival, and dmft/dmfs indexes, besides clinical and radiographic follow up at 6 and 12 months after the treatments. The carious dentin was collected before and after each treatment and the number of Streptococcus mutans, Streptococcus sobrinus, Lactobacillus casei, Fusobacterium nucleatum, Atopobium rimae and total bacteria were established by quantitative PCR.
