Summary
This summary is machine-generated.Globally, 34% of people experience Temporomandibular Disorders (TMDs), with higher prevalence in South America. Age 18-60 is most affected, and geographical location influences TMD incidence.
Area Of Science
- Epidemiology
- Public Health
- Oral Health
Background
- Temporomandibular Disorders (TMDs) represent a significant public health concern.
- Understanding the global prevalence and demographic distribution of TMDs is crucial for targeted interventions.
Purpose Of The Study
- To conduct a meta-analysis evaluating the global proportion of individuals with TMDs.
- To investigate the influence of geographical region, patient age, and sample size on TMD prevalence.
Main Methods
- A systematic literature search identified 6984 articles on TMD incidence.
- 74 studies encompassing 172,239 subjects were analyzed.
- Statistical analyses were performed using the R statistical language.
Main Results
- The global prevalence of TMDs was found to be 34%.
- Individuals aged 18-60 years exhibited the highest susceptibility to TMDs.
- Prevalence varied significantly by region: South America (47%), Asia (33%), and Europe (29%).
- A higher female-to-male ratio was observed in South America (1.56) compared to Europe (1.09).
Conclusions
- Geographical location appears to be a significant factor influencing TMD prevalence.
- Further epidemiological research on TMDs in African and Australian populations is warranted.
- The meta-analysis results are robust and unlikely to be significantly affected by publication bias.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
