An objective assessment of halitosis in children with adenoid vegetation during pre- and post-operative period

ObjectivesAlthough most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor.MethodsForty children with adenoid hypertrophy and 40 healthy subjects aged 5–15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H₂S), methyl mercaptan (CH₃SH), and dimethyl sulfide (CH₃)₂S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan).ResultsThe mean CH₃SH and (CH₃)₂S levels were significantly different (p < 0.05) between the adenoid hypertrophy group and the controls. The H₂S, CH₃SH, and (CH₃)₂S levels in the third postoperative month were significantly lower (p < 0.05) than those in the preoperative period, and there was no significant difference postoperatively between the patients with adenoid hypertrophy and controls. There was a positive correlation between age and VSC levels, and CH₃SH levels were significantly higher in patients with ventilation tube insertion, rather than just adenoidectomy.ConclusionsThere was a statistically significant association between halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.     

不同治疗方法对牙龈炎患者口气改善的效果评价

目的 探讨不同治疗方法对牙龈炎患者口气改善的效果。方法 按口臭程度分层，随机抽取牙龈炎患者60例，随机分为3组：洁牙组、漱口组、对照组。洁牙组进行超声波全口龈上洁治，漱口组使用龙掌口含液含漱1周。口气测量仪测定治疗前、治疗结束后1周、2周、1月的口气值，结果进行统计学分析。结果 实验前三组口气值无显著性差异。1周后，洁牙组与漱口水组口气值均降低，与对照组有显著性差异；2周后，漱口水组口气值回升，与对照组无显著性差异；1月后，洁牙组口气值亦有回升，但与其他两组相比，仍有显著性差异。结论 传统的洁治术对牙龈炎患者口气的改善是有效的。
