PAR evaluation of treated Class I extraction patients.
OBJECTIVE
To evaluate treatment changes and quality of finishing occlusion in Class I patients treated with four premolar extractions.


METHODS
Dental casts of 94 subjects (50 males and 44 females) were evaluated. Mean pretreatment age was 13.46 years, and mean treatment time was 2.09 years. The peer assessment rating (PAR) index was obtained from pretreatment and posttreatment dental casts.


RESULTS
The mean pretreatment PAR index of 29.46 was reduced to 6.32 at posttreatment stage, achieving a reduction of 78.54% with treatment. There was correlation between the initial PAR and correction during treatment, that is, the more severe the malocclusion the greater the treatment changes.


CONCLUSIONS
The cases evaluated showed a high-standard orthodontic finishing.
