Stomatological disorders in older people: An epidemiological study in the Brazil southern

Worldwide prevalence estimates of burning mouth syndrome: A systematic review and meta-analysis

OBJECTIVES

To evaluate the worldwide prevalence and epidemiology profile of burning mouth syndrome.

MATERIAL AND METHODS

A systematic review and meta-analysis was conducted. Search strategies were performed in PubMed, EMBASE, Web of Science, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang database for studies published before January 31, 2021, for the prevalence of burning mouth syndrome.

RESULTS

Eighteen articles were included. The overall pooled prevalence of burning mouth syndrome was 1.73% (95% CI = 0.176-0.351, n = 26,632) in general population, and 7.72% (95% CI = 0.434-0.691, n = 86,591) in clinical patients. The subgroup analysis by continent showed that among the population-based studies the prevalence in Asia (1.05%) lower than in Europe (5.58%) and North America (1.10%). The subgroup analysis by gender showed the prevalence of female (1.15%) was higher than male (0.38%) in general population. The subgroup analysis by age showed the prevalence was higher for people over 50 (3.31%) than under 50 (1.92%).

CONCLUSIONS

The pooled prevalence of burning mouth syndrome was relatively high in both general population and clinical patients, varies in different regions with the highest prevalence in Europe, and females over 50 years were the most susceptible group. More epidemiological surveys on the prevalence of burning mouth syndrome are needed.

Prevalence of Oral Mucosal Diseases in Older Adults in Mainland China: A Meta-Analysis of Observational Studies

Oral mucosal disease (OMD) is a public health challenge globally, but the epidemiological findings in older adults have been inconsistent in China. Thus, this meta-analysis was carried out to explore the prevalence of OMD and its moderating factors in this population. An electronic literature search was conducted of both international (PubMed, PsycINFO, and EMBASE) and Chinese (China National Knowledge Infrastructure and WanFang) databases from inception to November 1, 2019. The Der-Simonian and Laird random effects model was used to synthesize the prevalence of OMD and its 95% confidence intervals (95% CI). Twenty-four studies covering 23,653 older adults were included. The pooled prevalence of OMD was 23% (95% confidence interval: 17.9%-29.0%) Subgroup analyses and meta-analysis revealed that the prevalence of OMD was significantly associated with the reporting sampling, year of publication, and survey (all p values <0.05). This meta-analysis found that the prevalence of OMD among older adults in mainland China was significantly high. Early detection and effective intervention of OMD in older adults have public health and clinical importance.
