Abstract:
The aim of this study was to observe the prevalence of diagnostic groups of temporomandibular disorders (TMD) in patients who were referred or sought treatment for TMD and/or orofacial pain in a private clinic. The clinical records of 357 patients were evaluated and selected based on inclusion/exclusion criteria; the mean age was 32 years. A clinical examination was performed and the diagnosis was based on the American Academy of Orofacial Pain criteria. Results showed that 86.8% of patients were women and 93.3% of the patients presented more than one diagnosis. The most frequent chief complaint (n = 216, chi2 = 30.68, p = 0.001) and total diagnosis realized (n = 748, chi2 = 14.14, p = 0.001) were muscle related. We concluded that women seek treatment for dysfunction/disorders of orofacial structures more than men do; patients seeking specialized treatment have more than one diagnosis and muscle dysfunction is more prevalent than intra-articular disorders.

Teeth
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 and...

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
