Prospective case series on possible effects of local factors on the development of halitosis in new complete denture wearers.

Objectives: To assess the development of halitosis in participants wearing new removable complete dentures (RCD). Method and materials: Seventy-five completely edentulous patients receiving RCD were recruited. Halitosis was assessed by means of FitScan Breath Checker on the day of denture insertion (T0), as well as after 1 month (T1), and after 2 months (T2). Risk factors were studied using a validated questionnaire about oral and denture hygiene, and tongue scoring followed for each participant. A modified plaque scoring technique assessed the percentage of newly formed biofilms accumulated on all surfaces of the RCD. Results: At T0, 44% of the participants revealed halitosis. This percentage insignificantly increased at T1 (66.7%) and T2 (65.6%), respectively (P >. 109). At T1, halitosis was significantly lower among persons who reported tongue brushing compared to refraining participants (14.3% vs
