Patterns of service provision are expected to change over time, reflecting the dynamics of factors such as oral health status and trends in population demographics. The aim of this study was to identify trends in service provision over time. Data were collected from a random sample of Australian dentists in 1983-84, 1988-89, and 1993-94. Changes observed between 1983-84 and 1993-94 included a trend towards increased proportions of patients in older age groups, decreases in the percentage of persons receiving restorative care (from 40.2 per cent to 37.7 per cent) and prosthodontic care (9.3 per cent to 8.0 per cent), and increases in diagnostic (from 38.7 per cent to 46.0 per cent), preventive (20.9 per cent to 25.2 per cent), endodontic (5.3 per cent to 7.1 per cent), and crown and bridge services (3.1 per cent to 4.7 per cent) per visit. Other services such as orthodontic and general/miscellaneous services showed increases over the first half of the study period, but these did not continue between 1988-89 and 1993-94. The total number of services per visit increased over the study period for adult patients. These findings indicate changing patterns of practice over time, consistent with an increasing orientation towards prevention of disease and maintenance of a natural dentition.
随着时间的推移，服务提供模式预计会发生变化，这反映了诸如口腔健康状况和人口统计学趋势等因素的动态变化。本研究的目的是确定服务提供随时间的趋势。数据收集自1983 - 1984年、1988 - 1989年和1993 - 1994年澳大利亚牙医的随机样本。1983 - 1984年至1993 - 1994年期间观察到的变化包括：老年患者比例呈上升趋势，接受修复治疗（从40.2%降至37.7%）和口腔修复治疗（从9.3%降至8.0%）的人数百分比下降，而每次就诊时诊断（从38.7%升至46.0%）、预防（从20.9%升至25.2%）、牙髓病治疗（从5.3%升至7.1%）以及冠桥修复服务（从3.1%升至4.7%）的比例上升。其他服务，如正畸和一般/杂项服务在研究的前半期有所增加，但在1988 - 1989年至1993 - 1994年期间没有继续增长。在研究期间，成年患者每次就诊的服务总数有所增加。这些发现表明随着时间的推移，医疗实践模式在发生变化，这与越来越注重疾病预防和天然牙列维护的趋势相一致。
