This study used the American Board of Orthodontics (ABO) Objective Grading System (ABO index) (ABOI) to compare treatment outcome between patients treated by orthodontic specialists (OS) and patients treated by general dentists (GP). The sample (n = 196) consisted of 126 dental casts of patients treated by OS and 70 treated by GPs. All casts were collected in 1997 and 1998 from 10th grade students attending high schools in Cuyahoga County, Ohio, and were scored by 1 operator (Y.A.) calibrated in the use of the ABOI. The mean ABOI score for the OS group was 26.0 +/- 11.4 compared with 29.6 +/- 12.8 for the GP group. This difference was significant at the P < or = .05 level. Of the 7 components used in the ABOI, alignment of teeth was found to be the most significant between groups (OS mean = 5.39 +/- 4.37 versus GP mean = 7.8 +/- 5.21, P < or = .0007). In this sample, a significantly lower ABOI score was found for patients treated by OS compared with patients treated by GP.
本研究采用美国正畸委员会（ABO）客观评分系统（ABO指数）（ABOI），比较正畸专科医生（OS）治疗的患者与普通牙医（GP）治疗的患者之间的治疗效果。样本（n = 196）包括126例由OS治疗的患者的牙模和70例由GP治疗的患者的牙模。所有牙模均于1997年和1998年从俄亥俄州凯霍加县的十年级高中生中收集，并由1名经过ABOI使用校准的操作人员（Y.A.）进行评分。OS组的平均ABOI评分为26.0±11.4，而GP组为29.6±12.8。这种差异在P≤0.05水平上具有统计学意义。在ABOI使用的7个组成部分中，发现牙齿排列在两组之间差异最为显著（OS组平均值 = 5.39±4.37，而GP组平均值 = 7.8±5.21，P≤0.0007）。在该样本中，发现OS治疗的患者的ABOI评分显著低于GP治疗的患者。
