Core Tip

Core tip: Temporomandibular disorders (TMD) seem to occur more frequently in patients with irritable bowel syndrome (IBS). In this study we analyzed all patients for the presence of TMD according to the Research Diagnostic Criteria for Temporomandibular Disorders. Based on our results, IBS patients had a more than three times greater risk of TMD compared to healthy controls. The risk of having TMD was similar in different IBS subtypes. IBS patients that also fulfilled criteria for TMD seem to share along with chronic facial and abdominal pain a significant co-occurrence with psychiatric disorders and female preponderance.
