Assessment of photodynamic therapy with annatto and led for the treatment of halitosis in mouth-breathing children: Randomized controlled clinical trial.

Abstract

ObjectiveTo assess the effectiveness of antimicrobial photodynamic therapy (aPDT) employing an annatto-based (20%) dye combined with blue LED for the treatment of halitosis in mouth-breathing children.Materials and methodsFifty-two children six to twelve years of age with diagnoses of mouth breathing and halitosis (score of ≥ 3 on portable breath meter) Breath Alert™ (Tanita Corporation®-Japan), were randomly allocated to two groups (n = 26). Group 1: brushing, dental floss and aPDT applied to middle third of the dorsum of the tongue. Group 2: brushing, dental floss and tongue scraper. Breath meter results before, immediately after treatment as well as seven and 30 days after treatment were compared. The hypothesis of normality in the data was discarded by the Shapiro-Wilk test (p ResultsA significant difference was found between the pre-treatment reading and all other readings (p 0.05). However, significant differences were found between groups for all post-treatment assessments (p ConclusionAntimicrobial photodynamic therapy using annatto and blue LED proved to be a viable therapeutic option for the treatment of halitosis in mouth-breathing children.
