Abstract
Introduction: Gingival recession is the location of marginal periodontal tissues apical to the cemento-enamel junction, which can lead to many clinical problems. The prevalence, extension and severity of gingival recession present considerable differences among various study populations. Objective: To assess the prevalence, extension and severity of gingival recession among rural Nepalese adults. Materials & Method: The study was performed on 246 adult dentate rural patients above 20 years of age having at least 24 natural teeth. The prevalence, extension and severity of gingival recession were assessed by a single examiner using William’s graduated periodontal probe. Type and severity of gingival recession was recorded by using Miller’s criteria of apico-coronal height of recession defects. Result: Gingival recession was present in 65.44 % of the total study sample and mean number of teeth with gingival recession was 9.77. The prevalence of gingival recession was 41.37%, 58.90%, 77.41% and 86.79% in age groups of 20-29 years, 30-39 years, 40-49 years and ≥ 50 years respectively. In younger age groups Class I gingival recession was more prevalent whereas Class III and Class IV gingival recession was more prevalent in older age groups. Mandibular central incisors were the teeth most frequently affected by gingival recession (7.3%). Conclusion: 9.64% of teeth were affected by severe form of gingival recession at the age group 20-29 years as compared to 48.09 % at the age groups more than 50 years. High prevalence of gingival recession in adult subjects provides information about the importance of diagnosis and knowledge on these pathological gingival changes.

Highlights
Gingival recession is the location of marginal periodontal tissues apical to the cemento-enamel junction, which can lead to many clinical problems
Prevalence indicates number of cases or occurrences of gingival recession; extension corresponds to the number of teeth affected by gingival recession; and severity signifies the total root surface exposed by the gingival recession, i.e. the linear apico-coronal height of the gingival recession
This study reports 161 (65.44%) subjects found to be affected with gingival recession which is consistent with several other related studies,[16,17,21] and the prevalence is slightly higher than the findings of some other studies.[3,12,22]
Summary
Gingival recession is the location of marginal periodontal tissues apical to the cemento-enamel junction, which can lead to many clinical problems. The prevalence, extension and severity of gingival recession present considerable differences among various study populations. Gingival recession is defined as location of marginal periodontal tissues apical to cemento-enamel junction.[1] Recession may be localized to one tooth, or a group of teeth, or may be generalized throughout the oral cavity.[2] It may be associated with apical shift of marginal gingiva on one or more surfaces resulting in clinical attachment loss and root exposure that can lead to clinical problems such as root surface sensitive to hot and cold, caries, cervical root abrasions, erosions, plaque retention and aesthetic concern to the patient. Prevalence indicates number of cases or occurrences of gingival recession; extension corresponds to the number of teeth affected by gingival recession; and severity signifies the total root surface exposed by the gingival recession, i.e. the linear apico-coronal height of the gingival recession
