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.

口臭（halitosis）是吸烟者群体中的常见病症，且常与牙周疾病（periodontal disease）相关联。本数据集源自一项实验研究，旨在评估联合使用氯己定（chlorhexidine）漱口水与刮舌术（tongue scraping）的牙周治疗对吸烟者口臭的改善效果。

2025年9月至12月期间，佩德罗·恩里克·乌雷纳国立大学（Universidad Nacional Pedro Henríquez Ureña, UNPHU）牙科诊所牙周科接诊的50名吸烟者患者被纳入本研究。受试者被分为两组：对照组接受常规牙周预防性治疗（periodontal prophylaxis），实验组则在牙周预防性治疗的基础上，联合使用氯己定漱口水与刮舌清洁。

研究人员于三个时间点评估受试者的口臭状况：治疗前、操作结束后10分钟以及随访1周后。本数据集包含人口统计学变量（年龄与性别）、吸烟时长、牙周疾病诊断结果，以及通过感官评估（organoleptic evaluation）与数字化口气检测仪（digital breath analyzer）测得的口臭程度数据。

研究结果显示，随访1周后，实验组的口臭程度降幅更为显著，且被归类为无异味或轻度口臭的患者比例高于对照组。统计学分析证实两组间存在显著差异。

本数据集可用于评估联合机械与化学干预手段对合并牙周疾病的吸烟者口臭的管理效果，同时可为重复研究、对比研究及二次数据分析提供支撑。
