Abstract
PURPOSE: The aim of the present clinical trial was to evaluate the efficacy of antimicrobial photodynamic therapy (PDT) for the treatment of halitosis in elderly patients wearing dentures. METHODS: Elderly patients (>60 years age) wearing complete dentures and diagnosed with halitosis (H2S levels >112 ppb) were divided into two groups: patients undergoing treatment with tongue scraper and full mouth disinfection (Group I) and patients undergoing treatment with tongue scraper, full mouth disinfection and single application of PDT (Group II). Oral health related quality of life (OHRQoL) was assessed using a 14-point Likert scale used in oral health impact profile (OHIP). The assessment of halitosis was done with the help of a device called Oral Chroma™. Microbial sampling for detection of Porphyromonas gingivalis (P. gingivalis) was performed from the dorsum of the tongue using a sterile swab at baseline and after treatment on day 5, 15 and 30 and quantified using polymerase chain reaction. RESULTS: Forty elderly patients with halitosis completed the trial. The mean age in Group I and Group II was estimated to be 66.42 years and 67.91 years, respectively. Group II participants also maintained good OHRQoL in the post-operative period that reported statistically significant difference when compared with the control group (p < 0.01). Group II showed significant improvement in H2S concentration values at final analysis compared to Group-I (p = 0.001). P. gingivalis showed statistically significant reduction on day 5 only with PDT in Group II (p < 0.05). CONCLUSION: Antimicrobial PDT helped in reducing H2S gas concentration and improving quality of life in elderly patients wearing dentures. A significant reduction of P. gingivalis occurred only in the short-term follow-up.
