Abstract
Background and objectives: Gingival recession can cause several complications such as esthetics, root caries and plaque control that treatment of each necessitate time and cost from the patient. Regarding the importance of gingival recession, this study was undertaken in order to evaluate prevalence and severity of this clinical entity in anterior and premolar teeth.
Materials and Methods: This study was performed on 246 patients between 10-70 years old who referred to Tabriz Dental Faculty. All measurements of recession depth and width were done with periodontal probe and under sufficient illumination. Furthermore the type of gingival recessions was evaluated based on Miller’s classification. Some measurements were done twice randomly in order to examine intra-observer agreement of data. Statistical analysis was accomplished using Kappa, chi-square and T.Test.
Results: Our findings showed that 45.9% of patients had gingival recession. The trend of recession was upward between 10-30(22.3%) to 50-70 years of age (100%). Prevalence of recession in males was significantly higher than females (P <0.05).The most prevalent recession sites were detected in lingual surface of lower right lateral (37.4%),lower left lateral (37%), buccal surface of lower left central (20.7%), lower right central (20.3%), respectively. Class I Miller was the most common type of recession.
Conclusion: Considering the high prevalence of this clinical entity, implementation of oral hygeine instructions and conducting analytical and experimental researches would be a neccessity.
