Abstract

Many factors have been implicated in the etiology of gingival recession, including faulty toothbrushing, the position of the tooth in the arch(malalignment), the presence of inflammation, frenal attachment, impingement of restoration margins, orthodontic treatment and trauma from occlusion. Among the many factors, this study was to evaluate the relationship of occlusion and gingival recession.
640 teeth without other etiologic factors of gingival recession were evaluated in 40 subjects aged 21-59 years. Only 1st, 2nd premolar and molar were included in this study. We recorded nonworking contacts, working contacts, cervical abrasion, sex, gingival recession and evaluated that relation of occlusion and gingival recession.
The results of this study were as follows;
1. Teeth with nonworking contacts were significantly more gingival recession than teeth without nonworking contacts.(p<0.01)
2. Teeth with working contacts were significantly more gingival recession than teeth without working contacts.(p<0.01)
3. Teeth with cervical lesion were significantly more gingival recession than teeth without cervical lesion.(p<0.01)
4. Men's teeth were more gingival recession than women's teeth but it was not significant.(p>0.01)

Keywords: gingival recession, occlusion, working contact, nonworking contact
