Prevalence of temporomandibular disorders in the Brazilian population: A systematic review and meta-analysis

ABSTRACT

This systematic review aimed to assess the prevalence of temporomandibular disorders (TMD) in the Brazilian population, with studies that used the RDC/TMD or DC/TMD as diagnostic tools. A total of 6365 people from 11 studies were included. Sample mean age ranged from 12 to 69.5 years. The pooled prevalence of TMD was 33.6% (95% CI 31.5–35.8; I² = 37.2). Prevalence of TMD was higher in females (37.0%) than in males (29.3%). Our results indicate that TMD is a prevalent condition across Brazil’s territories. The results from this meta-analysis can help calculate more accurate sample sizes for future studies.
