AIM To investigate the prevalence and the risk of temporomandibular disorders(TMDs)in patients with irritable bowel syndrome(IBS)(including each subtype:constipation,diarrhoea,and mixed)compared to the general population.METHODS Between January 2014 and December 2015 we enrolled consecutively adult patients diagnosed with IBS at the outpatient clinic of the University of Salerno and healthy controls(HC)without IBS.At enrollment,we analyzed all patients for the presence of TMDs according to the Research Diagnostic Criteria for TMD.RESULTS We enrolled 91 IBS patients(23 IBS-D,30 IBS-C and38 IBS-M)and 57 HC in the study.We found a higher risk of having TMD(OR=3.41,95%CI:1.66-7.01)compared to the HC.The risk of having TMD was independent of IBS-subtype.Multiple regression analysis showed that facial pain was positively related to abdominal pain and higher level of depression.CONCLUSION IBS patients had a more than three times greater risk of TMD compared to HC.The risk of having TMDwas 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.Key words:Temporomandibular disorders;Irritable bowel syndrome;Chronic pain;Facial pain;Abdominal pain;Irritable bowel syndrome severity score symptoms;Irritable bowel syndrome predominant diarrhea;Irritable bowel syndrome predominant constipation;Irritable bowel syndrome mixed?The Author(s)2017.Published by Baishideng Publishing Group Inc.All rights reserved.

We found a higher risk of having TMD (OR = 3.41, 95% CI: 1.66-7.01) compared to the HC. risk of having TMD was independent of IBS-subtype. Multiple regression analysis showed that facial pain was positively related to abdominal pain and higher level of depression. CONCLUSION IBS patients had a more than three times greater risk of TMD compared to HC. risk. having TMDwas sim ilar 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.
