Consistency of orthodontic treatment planning decisions

Clin Orthod Res. 1999 May;2(2):79-84. doi: 10.1111/ocr.1999.2.2.79.

Abstract

Objective: (i) To analyse the consistency of a group of orthodontists' treatment decisions and (ii) to identify factors that may influence this consistency.

Design: Cross-sectional observational study.

Subjects: Ten orthodontists.

Methods: The orthodontists examined 60 case vignettes and recorded their treatment decisions on two separate occasions.

Main measure: Inter- and intra-examiner agreement was evaluated with the Kappa statistic.

Results: The consistency within each orthodontist was moderate. However, between-orthodontist consistency was poor.

Conclusion: It appears that there is marked variation between orthodontists in treatment planning decisions and this may reflect the lack of evidence for the effectiveness of competing treatments.
