2 /! % 01.,- + + * ) Gingival Recession: Prevalence, Extension, and Severity in Periodontal Department Patients Shareef Al Ashkar * Abstract This study was aimed to assess the gingival recession in 2250 adults individuals aged more than 20 years, randomly selected from the patients attending the periodontal department in dental school Damascus university. The sample included 1364 female, and 886 male. The subjects of both genders were divided in 4 groups according to the age rang. Two surfaces ( buccal,lingual ) were evaluated in each tooth, and linear measurements were obtained from the cementoenamel junction up to the gingival margin. Concerning the presence of gingival recession, which was recorded whenever there was 1mm or more of root surface exposed. Three categories were established according to the apicocoronal dimension of the root surface exposed by the gingival recession: simple, moderate, advance recessions. Gingival recession was observed in at least one dental surface in about 81% of the individuals analyzed. The prevalence, extension and severity of this clinical aspect increased with age, small recessions were the most frequent 41%,The occurrence of recession is more in female 93,44%,than male 83,59%.and more in mandibular 55,4% than maxilla 44,6%,and the most frequently affected tooth were the mandibular central incisors and maxillary first molar. The high prevalence of gingival recession in adult subjects provides information to the dental professionals as to the importance of the diagnosis and knowledge on these alterations. The higher prevalence, extension and severity observed in older subjects, in turn, suggests the cumulative effect of the lesion, associated to the longer period of exposure to the etiologic agents, which should be identified and removed as early as possible in order to reduce or even avoid worsening of the clinical condition. * Ass.
