The question of whether dentists who most frequently identify tooth surfaces for definite restoration perceive dental caries as significantly deeper than other dentists is assessed.
One group of 20 dentists independently examined 145 unrestored approximal tooth surfaces on 16 bitewing radiographs and recorded their restorative and depth decisions. Another group of 15 dentists similarly scored 304 unrestored surfaces on 30 bitewing radiographs. Each group of dentists was later divided into four subgroups according to the number of surfaces designated for definite restoration by each dentist.
As the number of tooth surfaces designated for definite restoration increased, mean caries depth (P < .05 for the high vs low subgroups) and the percent of dentinally carious surfaces increased, while the percent of surfaces assessed as sound decreased. Dentists with the lower numbers of surfaces designated for definite restoration came closest to the true histologic mean caries depth of the examined tooth surfaces.
Dentists who designated high numbers of approximal tooth surfaces for definite restoration assessed caries as deeper than other dentists, and deeper than was proven histologically.
评估那些最常确定牙齿表面需进行确定性修复的牙医是否认为龋齿比其他牙医所认为的明显更深。
一组20名牙医独立检查了16张咬合翼片上的145个未经修复的邻面牙齿表面，并记录他们关于修复和深度的判断。另一组15名牙医同样对30张咬合翼片上的304个未经修复的表面进行评分。之后，每组牙医根据每位牙医确定为需进行确定性修复的表面数量被分为四个亚组。
随着确定为需进行确定性修复的牙齿表面数量增加，平均龋损深度（高亚组与低亚组相比，P <.05）和牙本质龋表面的百分比增加，而被评估为健康的表面百分比下降。确定为需进行确定性修复的表面数量较少的牙医最接近所检查牙齿表面的真实组织学平均龋损深度。
确定大量邻面牙齿表面需进行确定性修复的牙医认为龋齿比其他牙医所认为的更深，且比组织学证实的更深。
