Abstract
Replies to questionnaires distributed to 340 boys and girls aged 13 to 15 years showed that the incidence of nailbiting was 45%. The possible effect of nailbiting on root resorption during orthodontic treatment was evaluated by radiographic examination of two groups, matched with regard to overjet, age, sex, and length and type of orthodontic treatment with fixed orthodontic appliances, one group consisting of 21 severe nailbiters and the other a group of 21 patients without the habit. The apical root resorption index was significantly higher in the nailbiters before (P<0.01) and after (P<0.001) orthodontic treatment.Keywords
