To find an association between self-reported change in oral health and dental treatment volume.
Baseline data were obtained from the Tasmanian component of the National Survey of Adult Oral Health 2004-06 and 12-month follow-up data from service use logbooks and mail self-complete questionnaires. The global oral health transition statement indicated change in oral health. Many putative confounders were analyzed and Poisson regression with robust variance estimation was used to calculate the prevalence ratios and 95 percent confidence intervals for bivariate- and multivariate-adjusted relationships.
One-eighth (12.4 percent) of the participants reported that their oral health had improved. Over half visited a dentist (n=176, 52.6 percent), of whom 105 received less than six dental services and 71 received six or more dental services. Baseline oral disease (P=0.01), having a treatment need (P<0.01), usually visiting a dentist for a problem (P<0.05), and having a lot of difficulty paying a $100 dental bill (P=0.01) were significantly associated with the same or worsening oral health. The regression model indicated that having six or more dental services (P<0.01) was significantly associated with improvement in oral health, indicating a threshold effect. Usually visiting a dentist for a check-up was significantly associated with improvement in oral health (P<0.01).
Having six or more dental services was significantly associated with a greater self-reported improvement in oral health than having less than six dental services. The greater prevalence ratios with increasing dental service volume suggested a threshold effect.
探讨自我报告的口腔健康变化与牙科治疗量之间的关系。
本研究数据来自于 2004-2006 年塔斯马尼亚州全国成人口腔健康调查的基线数据以及通过服务使用日志和邮寄自我完成问卷获得的 12 个月随访数据。全球口腔健康转变声明表明口腔健康发生了变化。分析了许多潜在的混杂因素，并使用泊松回归和稳健方差估计来计算二元和多元调整关系的患病率比和 95%置信区间。
八分之一（12.4%）的参与者报告口腔健康状况有所改善。超过一半的人（n=176，52.6%）曾看过牙医，其中 105 人接受的牙科服务少于 6 次，71 人接受的牙科服务超过 6 次。基线口腔疾病（P=0.01）、有治疗需求（P<0.01）、通常因问题而看牙医（P<0.05）以及支付 100 美元的牙科账单有很大困难（P=0.01）与口腔健康状况相同或恶化显著相关。回归模型表明，接受 6 次或更多次牙科服务（P<0.01）与口腔健康的改善显著相关，表明存在阈值效应。通常因检查而看牙医与口腔健康的改善显著相关（P<0.01）。
与接受少于 6 次牙科服务相比，接受 6 次或更多次牙科服务与自我报告的口腔健康改善显著相关。随着牙科服务量的增加，患病率比也显著增加，表明存在阈值效应。
