Chin Position: to treat or not to treat

Abstract

This study was conducted to compare the mean preference scores for orthodontic treatment need, considering the chin position, amongst orthodontists, orthodontic patients and their parents. Male and female profile silhouettes were prepared by changing their chin prominence using Adobe Photoshop 7 with zero degree meridian as line of reference. Rating of these silhouettes was done by the three groups of raters (orthodontists, orthodontic patients and their parents) on a scale of four with one being no need of treatment and four being severe need of treatment. There was a statistically significant difference seen amongst orthodontists and the orthodontic patients and also amongst the orthodontist and the orthodontic patient's parents for the 2mm and 4mm chin position with orthodontists scoring a higher need of treatment as compared to the patients and parents.
