Orthodontic Treatment Characteristics and Outcomes in an Educational Setting

Abstract EN

Background.

To assess and correlate orthodontic treatment characteristics and outcomes in an educational setting.

Methods.

A total of 287 patients were included.

Independent chart reviews were conducted to gather demographic and pretreatment diagnostic information.

Posttreatment digital records were graded with the ABO C-R Eval and the CCA methods.

Pearson correlation coefficients were calculated to determine associations between variables.

Results.

Of the 287 patients, 122 (42.5%) were male and 165 (57.5%) were female.

The total average treatment time was 33.87 ± 10.28 months, with a range from 11 to 75 months.

The mean ABO C-R Eval score was 29.10 ± 8.59 points.

The parameters with the highest scores were buccolingual inclination and occlusal contacts.

The mean CCA score was 3.36 ± 2.05 points.

The highest scores were recorded for dental esthetics and management of the periodontium.

Higher ABO DI scores were weakly correlated with longer treatment times (r = 0.258; p<0.001).

ABO C-R Eval scores showed a weakly significant association with treatment duration (r = 0.162; p=0.006), while CCA scores were moderately associated with treatment duration (r = 0.451; p<0.001).

Conclusions.

As treatment duration increased, the total ABO C-R Eval and CCA scores tended to increase; thus, quality of treatment outcomes decreased.

A significant positive correlation was also found with the ABO DI score and treatment duration.
