To assess halitosis and determine the relationship between halitosis and tongue scores, periodontal status and DMFT among dental students.
The study comprised 268 (178 female, 90 male) dental students. Halitosis was measured using a Halimeter and the organoleptic method. Halitosis was diagnosed with a mean volatile sulphur compounds (VSC) level of >=125 ppb and an organoleptic measurement of >= 2 on a 0- to 5-point scale. Tongue scores were obtained using a tongue coating index (TCI), periodontal status was measured and assessed using the Community Periodontal Index of Treatment Needs (CPITN) and DMFT indices were calculated.
Halitosis occurred at higher rates among male students than female students (83% vs 71%, P = 0.02). No differences were found in halitosis rates among students in different academic years (P = 0.6) or age groups (P = 0.6). A relationship was found between halitosis and tongue scores (P < 0.001) and between halitosis and mean CPITN scores (P = 0.004). The mean DMFT was 4.02 (SD = 3). No relationship was found between halitosis and DMFT index (P = 0.5).
Halitosis was prevalent among dental students. Given their responsibilities for diagnosing and improving oral health, they may benefit from increased awareness of the problem and encouragement to improve their own oral hygiene, especially male students.
评估口腔异味情况，并确定口腔异味与牙科学生的舌部评分、牙周状况及龋失补指数（DMFT）之间的关系。
该研究纳入了268名牙科学生（178名女性，90名男性）。使用口腔气体分析仪和感官评估法测量口腔异味。当平均挥发性硫化物（VSC）水平≥125 ppb且感官评估在0至5分的量表上≥2分时，诊断为口腔异味。使用舌面覆盖指数（TCI）获得舌部评分，采用社区牙周治疗需要指数（CPITN）测量和评估牙周状况，并计算DMFT指数。
男学生的口腔异味发生率高于女学生（83%对71%，P = 0.02）。不同学年（P = 0.6）或年龄组（P = 0.6）的学生在口腔异味发生率上未发现差异。发现口腔异味与舌部评分之间存在关联（P < 0.001），以及口腔异味与平均CPITN评分之间存在关联（P = 0.004）。平均DMFT为4.02（标准差 = 3）。未发现口腔异味与DMFT指数之间存在关联（P = 0.5）。
口腔异味在牙科学生中很普遍。鉴于他们在诊断和改善口腔健康方面的职责，提高对该问题的认识并鼓励他们改善自身口腔卫生可能会使他们受益，尤其是男学生。
