Temporomandibular disorders (TMDs) and irritable bowel syndrome (IBS) are linked, with each condition worsening the other. Combined treatments may improve patient quality of life, but more research is needed.
Area of Science:
- Medical Science
- Gastroenterology
- Dentistry
Background:
- Temporomandibular disorders (TMDs) involve the temporomandibular joint and masticatory muscles, causing orofacial pain and restricted jaw movement.
- Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain and altered bowel habits.
- Existing research suggests a correlation between TMD and IBS, impacting quality of life and potentially leading to widespread pain.
Purpose of the Study:
- To examine the correlation between TMD and IBS.
- To investigate the pathology, frequency, and severity of both conditions.
- To explore the influence of nervous and endocrine systems on TMD and IBS.
Main Methods:
- A scoping review was conducted.
- Studies were identified using PubMed, SCOPUS, Web of Science, and Google Scholar.
- Fifty-eight clinical papers met the eligibility criteria for inclusion.
Main Results:
- TMD and IBS significantly enhance the development of one another.
- Mutual comorbidities and high comorbidity rates were observed in patients with both conditions.
- Both conditions were found to modify central nervous system processing.
Conclusions:
- A bidirectional relationship exists between TMD and IBS.
- Integrated dental and gastroenterological treatments can improve patient quality of life.
- Further research is recommended for a holistic treatment approach.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
