The present study assessed halitosis after treatment of gingivitis by using different diagnostic modalities.
A total of 27 patients (47 ± 7 years old; 14 women, 13 men) diagnosed with chronic periodontitis underwent supragingival mechanical debridement (day 0). Measurement of volatile sulfur compounds (VSC), visual analogue scale (VAS) and organoleptic assessment, visible plaque index (VPI) and gingival bleeding index (GBI) were obtained at baseline (prior to treatment of gingivitis) and then after 30, 90, and 180 days. The Friedman test was used to compare outcome data at days 0, 30, 90, and 180. Post-hoc comparison (tongue cleaning and non-cleaning) was performed using the Student t test for VSC and VAS and the Mann-Whitney test for organoleptic measurements. The level of significance was set at 5%.
VSC and VAS means (days 0 and 180) were, respectively, 463.41 ppb (± 496.12 ppb) and 245.96 ppb (± 301.51 ppb) and 6.28 cm (± 2.23 cm) and 5.03 cm (± 2.01 cm). The frequency of high organoleptic scores (3 to 5) declined from 96.29% (day 0) to 81.48% (day 30), with a reduction of around 50% at day 180. Post-hoc comparison did not reveal any significant differences between the indicators analysed.
Supragingival plaque control reduced halitosis in patients with periodontitis, but tongue cleaning vs no tongue cleaning did not yield different results.
本研究采用不同诊断方式评估牙龈炎治疗后的口臭情况。
共有27例诊断为慢性牙周炎的患者（年龄47±7岁；女性14例，男性13例）接受了龈上机械清创术（第0天）。在基线（牙龈炎治疗前）以及30、90和180天后，分别测量挥发性硫化物（VSC）、视觉模拟量表（VAS）和感官评估、可见菌斑指数（VPI）以及牙龈出血指数（GBI）。采用Friedman检验比较第0、30、90和180天的结果数据。使用Student t检验对VSC和VAS进行事后比较（清洁舌与未清洁舌），并使用Mann-Whitney检验对感官测量结果进行事后比较。显著性水平设定为5%。
VSC和VAS均值（第0天和第180天）分别为463.41 ppb（±496.12 ppb）和245.96 ppb（±301.51 ppb），以及6.28 cm（±2.23 cm）和5.03 cm（±2.01 cm）。高感官评分（3至5分）的频率从第0天的96.29%降至第30天的81.48%，在第180天减少了约50%。事后比较未发现所分析指标之间存在任何显著差异。
龈上菌斑控制可减轻牙周炎患者的口臭，但清洁舌与未清洁舌并未产生不同结果。
