Efficacy in the periodontal treatment of halitosis in smoking patients using a chlorhexidine- based mouthwash in combination with tongue cleaners.

Halitosis is a common condition among smokers and is frequently associated with periodontal disease. This dataset derives from an experimental study aimed at evaluating the effectiveness of periodontal treatment combined with chlorhexidine mouthwash and tongue scraping in reducing halitosis in smokers. A total of 50 smoker patients treated at the Periodontology Department of the dental clinic of the Universidad Nacional Pedro Henríquez Ureña (UNPHU) between September and December 2025 were included. Participants were assigned to two groups: a control group that received conventional periodontal prophylaxis and an experimental group that received periodontal prophylaxis plus chlorhexidine mouthwash and tongue cleaning. Halitosis was assessed at three time points: before treatment, ten minutes after the procedure, and one week later. The dataset includes demographic variables (age and sex), smoking duration, periodontal diagnosis, and halitosis levels measured using organoleptic evaluation and a digital breath analyzer. The findings show a greater reduction in halitosis levels in the experimental group after one week of follow-up, with a higher proportion of patients classified as odor-free or with mild halitosis compared to the control group. Statistical analysis demonstrated significant differences between groups. This dataset enables the evaluation of combined mechanical and chemical interventions for managing halitosis in smokers with periodontal disease and may support replication studies, comparative research, and secondary data analyses.
