Abstract
Preclinical year dental students (100) were examined. Oral hygiene status and gingival conditions were determined using the plaque index score and the gingival index score systems. The width of the attached gingiva and the depth of the gingival pockets were evaluated. The gingival recessions were recorded and their heights measured from the CEJ [cementoenamel junction] to the gingival margin. No significant correlation was found between oral hygiene and gingival recession, oral hygiene and width of attached gingiva, gingival conditions and width of attached gingiva. Only a negative correlation (P < 0.05) was found between the width of attached gingiva and the number of gingival recessions. No statistically significant differences were observed in oral hygiene status and gingival conditions among 3 groups of students (without, with 1 and with 2 or more recessions, respectively). The roles of toothbrushing trauma and adequate width of attached gingiva in the etiology of gingival recessions are questioned.
