Using the information obtained from the Collegiate Patient Management System a comparison of average numbers of procedures performed by third year dental students from 1983/84 to 1996/97 was made. The data were grouped in order to compare Group I (1983/1989) to Group II (1990/1997). Student's t-tests were performed to determine significant differences between the groups for the various procedures. The number of new patients in Group I was only 8.2 compared to Group II--7.9 and the total number of new and recall patients seen by students was Group I--33.5 compared to Group II--29.9. Students in Group I performed 19.3 one-surface restorations compared to 11.8 (p = .0001) in the later group and 9.5 two-surface restorations compared to 6.0 (p = .0003) for the 1990's group. Stainless steel crowns, pulpotomies, extractions and sealants were also compared. The total numbers of patients visits was 66.8 in GRP I compared to 49.6 (p;eq.0001) in GRP II. There has been a decrease in most student experiences in the undergraduate pediatric dental clinic in the past 15 years.
利用从大学患者管理系统获得的信息，对1983/84至1996/97年三年级牙科学生所实施操作的平均数量进行了比较。数据被分组以便将第一组（1983/1989年）与第二组（1990/1997年）进行比较。进行了学生t检验以确定两组在各种操作方面的显著差异。第一组的新患者数量为8.2，而第二组为7.9；学生诊治的新患者和复诊患者总数，第一组为33.5，而第二组为29.9。第一组学生进行了19.3次单面修复，而90年代的第二组为11.8次（p = 0.0001）；第一组进行了9.5次双面修复，而第二组为6.0次（p = 0.0003）。还对不锈钢冠、牙髓切断术、拔牙和窝沟封闭进行了比较。第一组的患者就诊总数为66.8，而第二组为49.6（p = 0.0001）。在过去15年里，本科小儿牙科诊所中大多数学生的临床经验有所减少。
