Frequency of Oral Anatomic Variations and Mucosal Lesions Among a Defined Group of Elderly Dental Patients in Iran

Abstract

histopathologically. Data were analyzed by the Chi-square test and logistic regression by means of the SPSS software version 18. Results: Out of the 129 elderly participants, aged between 60-87 years (mean: 66.71 ± 6.21), males constituted 58.1% (n = 75) of patients and female were 41.9% (n = 54). Normal variations of oral mucosa were observed in 62% (n = 80) of patients, while 44.2% (n = 57) had oral mucosal lesions. Normal variations were significantly associated with smoking (OR = 1.2), while denture wearers were at higher risk of oral pathological lesions (OR = 1.5). Meanwhile, the frequency of normal variations in men was 1.3 folds higher than that of women (P = 0.04). Conclusions: The frequency of normal variations and oral lesions among elderly dental patients is high, and this is significantly associated with smoking, denture wearing and male sex.
