Abstract

Aim: This study aimed to compare the effectiveness of chlorhexidine and probiotic-containing mouthwashes in reducing halitosis among RPD and FPD wearers.
Materials and methods: This randomized, double-blind controlled trial included 40 participants (20 RPD, 20 FPD wearers). Participants were assigned to Group I (chlorhexidine mouthwash) or Group II (probiotic mouthwash). Pre- and post-experiment halitosis levels were assessed using organoleptic breath assessment by an examiner and self-evaluation by participants. Wilcoxon signed ranks test, Mann-Whitney U test, and chi-square test were used for statistical analysis (P<0.05 considered significant).
Results: Both mouthwashes significantly reduced halitosis in RPD wearers (P<0.05), with no significant difference between groups. However, probiotic mouthwash demonstrated a significantly greater reduction in halitosis among FPD wearers (P<0.05) when assessed by the examiner.
Conclusion: Probiotic mouthwash was found to be as effective as chlorhexidine in RPD wearers and superior in FPD wearers. These findings suggest that probiotics can serve as an alternative to chlorhexidine, particularly for fixed prosthesis users, without associated side effects.
