Oral mucosal lesions in elderly dental patients in Sana’a, Yemen

Abstract

Objectives:

With aging, the oral mucosa becomes more susceptible to external stimuli. The aims of this study were to obtain baseline data on the prevalence of oral mucosal lesions (OMLs) in a population of elderly Yemeni patients and to investigate differences in the presentation of these findings in relation to age, gender, education level, and the wearing of dentures.

Patients and Methods:

The prevalence of OMLs was assessed by clinical examination of a sample of 310 elderly Yemeni patients aged 60 years and older. A single examiner performed detailed oral examinations of the oral cavity according to international criteria and the World Health Organization codes.

Results:

The overall prevalence of OMLs was 77.1%, with a significant difference ( P < 0.05) between men (80.3%) and women (69.6%). The prevalence rate of OMLs indicated a significant decrease with advancing age. The most frequently observed lesions were fissured tongue (34.2%), benign tumors (17.1%), hairy tongue (16.5%), and qat-induced white lesions (12.6%). Hairy tongue, qat-induced white lesions, and shammah keratosis were associated with men ( P < 0.01, P < 0.05, and P < 0.05, respectively), whereas geographic tongue was associated with women ( P < 0.05). The presence of one or more lesions was significantly associated with low education level ( P < 0.05). Certain OMLs showed a significant association with smoking and qat chewing ( P < 0.05). No association was found between the occurrence of OMLs and denture wearing ( P > 0.05).

Conclusions:

The present study has shown a high prevalence of oral lesions among Yemeni elders.
