Quantitative assessment of orthodontic treatments performed by graduate orthodontic students of an International School of Dentistry.

Context: Assessing and monitoring treatment quality within graduate courses are vital for maintaining high standards and addressing areas needing improvement. In this study, we evaluated the treatment quality delivered by measuring the total scores obtained from the comprehensive clinical assessment (CCA) index and the objective grading system (OGS) index.

Aims: This study aimed to evaluate the quality of orthodontic treatments administered by graduate students by using the CCA index and OGS index.

Settings and design: The research was carried out at the Orthodontic Department of Mashhad School of Dentistry, focusing on a cross-sectional analysis of orthodontic treatments administered by graduate students.

Methods and material: The study randomly selected 36 cases from the department's archives and evaluated them through pre- and post-treatment analyses, including radiographs, photographs, and dental casts. The evaluation employed the CCA and the OGS indices.

Statistical analysis used: Data analysis was performed using the Spearman and Mann-Whitney tests.

Results: The CCA correlated with the patient's age and gender and was statistically significant (P = 0.007 and P = 0.010, respectively). The CCA index was substantially associated with treatment duration (P = 0.032 a). There was no significant relationship between OGS and CCA (P = 0.223). The mean of post-treatment OGS was 18.97. All criteria of OGS and the overall score were improved significantly (P < 0.001).

Conclusions: The results of this study suggested that orthodontic treatment results provided by the investigated program have high scores and meet high standards of the CCA and OGS indices.
