The purpose of this study was to evaluate how incremental information obtained from different types of diagnostic records contributes to the determination of orthodontic treatment decisions. Pretreatment records of 57 orthodontic patients were assessed by five orthodontists who were part-time faculty members and also in private practice. This sample consisted of dental school orthodontic patients who had Class II malocclusions and included patients at three different dental developmental stages. The following diagnostic records were used: study models (S), facial photographs (F), a panoramic radiograph (P), a lateral cephalogram (C), and its tracing (T). Five combinations of diagnostic records were presented to the orthodontists in the following sequence: (1) S; (2) S + F; (3) S + F + P; (4) S + F + P + C; and (5) S + F + P + C + T. The simultaneous interpretation of all diagnostic records (S + F + P + C + T) was used as the "diagnostic standard." There was a diagnostic standard for each of the patients and for each of the orthodontists. The diagnostic standard was achieved: (1) S = 54.9%, (2) S + F = 54.2%, (3) S + F + P = 60.9%, and (4) S + F + P + C = 59.9%. Thus, in a majority of cases (55%), study models alone provided adequate information for treatment planning, and incremental addition of information from other types of diagnostic records made small differences.
本研究的目的是评估从不同类型诊断记录中获取的增量信息如何有助于确定正畸治疗决策。57名正畸患者的治疗前记录由5名正畸医生进行评估，这些医生均为兼职教员且同时从事私人执业。该样本包括患有安氏II类错牙合畸形的牙科学院正畸患者，并涵盖处于三个不同牙齿发育阶段的患者。使用了以下诊断记录：研究模型（S）、面部照片（F）、全景X线片（P）、头颅侧位片（C）及其描图（T）。五种诊断记录组合按以下顺序呈现给正畸医生：（1）S；（2）S + F；（3）S + F + P；（4）S + F + P + C；以及（5）S + F + P + C + T。所有诊断记录的同时解读（S + F + P + C + T）被用作“诊断标准”。每位患者和每位正畸医生都有一个诊断标准。达到诊断标准的比例如下：（1）S = 54.9%，（2）S + F = 54.2%，（3）S + F + P = 60.9%，以及（4）S + F + P + C = 59.9%。因此，在大多数情况下（55%），仅研究模型就为治疗计划提供了足够的信息，而从其他类型诊断记录中增量添加信息产生的差异较小。
