To quantify the relationship between receipt of routine dental care and the use of non-trauma related emergency dental services.
A multiple logistic regression was run on administrative dental claim and encounter data. The model dependent variable was the use of non-trauma related emergency dental care. Predictors included previous year oral examinations, radiographs, dental cleanings and, as a control, member age.
Administrative data were obtained from a dental health maintenance organisation located in the state of Texas.
Claim and encounter data for 2,947 insured members were used, representing experience from 1995 through 1996.
The outcome of interest was the use of non-trauma related emergency dental services.
Results demonstrated empirically that those who availed themselves of preventive dental services were significantly less likely to use non-trauma related emergency services (P<0.01). The probability of needing non-trauma related dental services in 1996 was 42.7% lower among those who had an examination in 1995 when compared with those who did not. When analysed in a simple logistic regression, dental cleanings in 1995 were also significantly associated with a decreased probability of needing non-trauma related emergency services. However, this relationship did not hold in the controlled model, which was probably due to multicollinearity.
This study provides evidence of the value of periodic preventive dental examinations and services. Those who receive such services are less likely to use non-trauma related emergency dental services.
量化接受常规牙科护理与使用非创伤性相关急诊牙科服务之间的关系。
对牙科行政索赔和就诊数据进行多元逻辑回归分析。模型的因变量是使用非创伤性相关急诊牙科护理。预测因素包括上一年的口腔检查、X光检查、牙齿清洁，以及作为对照的会员年龄。
行政数据来自位于德克萨斯州的一家牙科健康维护组织。
使用了2947名参保会员的索赔和就诊数据，代表了1995年至1996年的情况。
关注的结果是使用非创伤性相关急诊牙科服务。
实证结果表明，接受预防性牙科服务的人使用非创伤性相关急诊服务的可能性显著降低（P<0.01）。与未在1995年进行检查的人相比，1995年接受检查的人在1996年需要非创伤性相关牙科服务的概率低42.7%。在简单逻辑回归分析中，1995年的牙齿清洁也与需要非创伤性相关急诊服务的概率降低显著相关。然而，这种关系在控制模型中并不成立，这可能是由于多重共线性。
本研究提供了定期预防性牙科检查和服务价值的证据。接受此类服务的人使用非创伤性相关急诊牙科服务 的可能性较小。
