Comparative study of photodynamic therapy with LED and probiotics in the treatment of halitosis: protocol for a randomised controlled clinical trial.

ABSTRACT:

Introduction

Halitosis is a term that defines any unpleasant odour smell originating from the oral cavity and may have a local or systemic origin. This project aims to determine the effectiveness of treatment involving antimicrobial photodynamic therapy (aPDT) combined with treatment using probiotics at reducing halitosis.

Methods and analysis

92 individuals from 18 to 60 years of age with a diagnosis of halitosis (sulfide≥112 ppb, gas chromatography) will be selected. The participants will be randomly allocated to four groups (n=23). Group 1 (control): brushing, dental floss and tongue scraper; group 2: brushing, dental floss, tongue scraper and aPDT with blue Light Emitting Diode (LED) +annatto; group 3: brushing, dental floss, tongue scraper and aPDT with blue Light Emitt
