Aim: To assess the effectiveness of four commercially available mouthrinses in the treatment of halitosis of oral origin. Materials and methods: Forty patients with halitosis of oral causes and willing to participate in the study were recruited. The inclusion criteria were: halitosis of oral origin, systemically healthy patient, baseline levels of volatile sulfur compounds(VSC) ≥ 2 (using halimeter). The participants were randomly allocated to the following groups: group A - Rexidine® mouthrinse, group B - Colgate total® mouthrinse, group C -Listerine® mouthrinse, group D - Hiora® mouthrinse. The baseline scores of volatile sulfur compounds were recorded using a Halimeter (Tanita Breathalert™). The patients were advised to use the mouthrinses as per the manufacturer’s recommendation. The VSC scores were recorded again after 7 days & 15 days. The patient’s feed-back for any adverse effects was also recorded. Results: All the four mouthrinses were effective in managing halitosis of oral origin. Participants of group C using Listerine® mouthrinse displayed maximum reduction of VSC, both on day 7 and 15. Following this was group B (Colgate total®) & then group A (Rexidine®). Group D (Hiora®) showed minimum reduction in VSC compared to the other 3 groups assessed.
