The purpose of this study was to examine the trends in numbers, demographic characteristics, and treatment history of pediatric dental patients under the care of dental students over the period 1980 through 1994. Data were collected for: exams, sealants, surfaces of amalgam, composite resin surfaces, pulpotomies, stainless steel crowns, and extractions. Correlations were done across the 15-year period to determine significant trends over time. During the 15-year period, the average number of patient visits required for each student to complete the requisite number of patients, declined from 45 appointments to complete 10 patients in 1980, to 35 visits to complete 13 patients in 1994. Over time, the numbers of amalgam surfaces, pulpotomies, extractions and stainless steel crowns decreased significantly, while the number of composite resin surfaces increased (P < 0.05). Based on a previous outcome assessment that indicated declining numbers of procedures performed between 1980 and 1985, the required number of patients treated per student was raised from 10 to 13, beginning with the 1986 class.
本研究的目的是调查1980年至1994年期间在牙科学生治疗下的儿童牙科患者的数量、人口统计学特征和治疗史的变化趋势。收集了以下数据：检查、窝沟封闭、银汞合金充填面、复合树脂充填面、牙髓切断术、不锈钢冠修复和拔牙。对这15年期间的数据进行相关性分析，以确定随时间推移的显著趋势。在这15年期间，每名学生完成规定患者数量所需的平均就诊次数从1980年完成10名患者所需的45次预约，降至1994年完成13名患者所需的35次就诊。随着时间的推移，银汞合金充填面、牙髓切断术、拔牙和不锈钢冠修复的数量显著减少，而复合树脂充填面的数量增加（P<0.05）。基于先前一项结果评估显示1980年至1985年期间治疗操作数量下降，从1986级开始，每名学生所需治疗的患者数量从10名增加到13名。
