ABSTRACT:
Background: Gingival recession (GR) is a disorder affecting almost all middle and older-aged individuals to some extent; a need to study its epidemiology in Egypt would be of interest.
Aim: Epidemiology of GR in North Sinai: Incidence, Severity, Distribution and Risk indicators.
Subjects & Method: A total sample of 1908 individuals from different parts of North Sinai governorate was assigned upon the last Egyptian population census. Data collection: a. Questionnaire: A descriptive questionnaire was filled. b. Clinical examination: GR was recorded with Miller's classification. Verbal and written consent was obtained. Data were analyzed using SPSS 20.0.
Results: The prevalence of GR was 41.6 %; showed the highest distribution among age groups of 36-45 and 46 – 60 years old. The predominance of GR at posterior areas on both lower and upper arches was noted as these areas showed statistically significant more GR compared to anterior areas on the two arches (p < 0.05).
Conclusion: The prevalence of GR is more in males than females. It was found to be more common in the maxillary posterior area than in other sites. Gender, age and oral hygiene are the major etiologic factors that affect GR incidence. Systemic conditions especially smoking are major risk factors in GR prevalence.
