Brief Summary

Cigarette smoking in conjugation with bad oral hygiene is considered a typical predisposing factor for many oral diseases including denture stomatitis. This study investigated the effect of Rose Bengal (RB)-and Curcumin (CUR)-mediated photodynamic therapy (PDT) in comparison with nystatin therapy in the intervention of denture stomatitis in cigarette smokers. Overall, 45 habitual cigarette smokers aged \~58 years having denture stomatitis were categorized into three groups: Group-I - RB-mediated PDT, Group-II - CUR-mediated PDT, and Group-III - Nystatin therapy. The primary outcome of the interest was: counts of Candida colony from denture surface and palatal mucosa, calculated as CFU/mL, whereas the prevalence of Candida species determined in 3 research groups comprised the secondary outcome. Oral swab specimens were gathered from the denture surfaces and palatal mucosa. All clinical assessments were performed at baseline, 6 weeks, and 12 weeks. C. albicans was the most prevalent yeast identified on both denture surfaces and palatal mucosa, followed by C. tropicalis and C. glabrata. A considerable decrease in the CFU/mL scores were observed in Group-I and Group-II at the end of the interventions and on the 12-week follow-up (p\<0.05). Group-I, II, and III demonstrated clinical efficacy rates of 53%, 51%, and 49%, respectively. CUR-and RB-mediated PDT was found to be as effective as topical Nystatin therapy for the intervention of denture stomatitis among cigarette smokers.

Rose Bengal-mediated Photodynamic therapy

EXPERIMENTAL

Participants belonging to the rose bengal mediated photodynamic therapy, their dentures and oral cavity were illuminated using the LED device for 26 minutes (37.5 J/cm2). The photosensitizer rose bengal was sprayed on the palate and dentures for half-hour. To irradiate the palate, the investigator handled the other LED device; the circular platform having LEDs was put within the patient's oral cavity and the illumination of the palate was carried out for 20 minutes (122 J/cm2). The PDT was carried out thrice per week for a half month (6 sessions) in each participant.

Drug: Rose Bengal

Curcumin-mediated photodynamic therapy

EXPERIMENTAL

Participants belonging to the curcumin mediated photodynamic therapy, their dentures and oral cavity were illuminated using the LED device for 26 minutes (37.5 J/cm2). The photosensitizer curcumin was sprayed on the palate and dentures for half-hour. To irradiate the palate, the investigator handled the other LED device; the circular platform having LEDs was put within the patient's oral cavity and the illumination of the palate was carried out for 20 minutes (122 J/cm2). The PDT was carried out thrice per week for a half month (6 sessions) in each participant.

Drug: Curcumin

Nystatin therapy

ACTIVE COMPARATOR

Participants belonging to the Nystatin group were administered the topical nystatin-based antifungal drug.

Drug: Nystatin

Interventions

Curcumin was bought from Sigma®, USA, and its solution was freshly prepared by mixing curcumin powder with phosphate-buffered saline.
