    • Abstract:
      Objectives: T he aims of this study were twofold: 1) to evaluate the prevalence and severity of traumatic gingival recessions (GR ) in a sample of dental students; and 2) to assess the influence of oral hygiene related factors in the development of such lesions. Material and Methods: F rom the initial sample of 250 dental students enrolled, 80 fulfilled the inclusion criteria. O ne calibrated examiner interviewed all students using a written questionnaire. T he same examiner then assessed the presence of buccal GR . Logistic regression analysis was performed to investigate the association between GR , hygiene habits and deterioration of toothbrush bristles. R esults: O verall, the prevalence of GR was 86.25 per cent, and the average rate of GR per patient was 4.05. O nly the independent variable-deteriorated toothbrush bristles, p=0.02-was found to correlate with the occurrence of GR , with odds ratio of 2.77 and 95% confidence interval of 1.15-6.70. Conclusion: T he development of GR was associated with deterioration of toothbrush bristles. F urther investigation, focusing on the effect of traumatic toothbrushing, is required.
