The aim of this study was to estimate the prevalence of temporomandibular disorders (TMD) symptoms in an Italian population sample, focusing on gender and age differences. We selected 2005 individuals by telephone survey and asked them about TMD symptoms like difficulty in jaw movement, jaw pain and joint sounds. Also, tooth-clenching and/or tooth-grinding habits were investigated. Of the study population, 8·1% reported limitations in jaw movements, 5·1% reported jaw pain and 33·3% reported joint sounds. Furthermore, 37·3% reported tooth-clenching/tooth-grinding. Confidence intervals of proportions were calculated. Significant gender differences were found for jaw limitation and pain (chi-square test; P < 0·05). Symptoms reduced with increasing age. The prevalence of TMD symptoms in the Italian population was consistent with data reported from similar studies. Gender and age differences were found for jaw pain and limitation in jaw movements.
Background. Different surgical variables are assumed to play a role in
postoperative course after lower third molar extraction. The aim of study was
to assess whether flap design and duration of surgery can influence acute
postoperative symptoms and signs after lower third molar extraction.
Methods.
Twenty-five patients
scheduled for lower third molar extraction were included in this study and
randomly assigned to two groups in terms of flap design: group A (envelope
flap) and group B (triangular flap). Swelling and trismus were assessed
before and after surgery on days 0, 2 and 7. Pain was assessed for seven days
after surgery. Maximum postoperative pain was chosen as the main outcome
variable. ANOVA was used to assess differences between the groups regarding
maximum postoperative pain, trismus and swelling at 2- and 7-day intervals.
Pearson's correlation coefficient was used to assess correlation between
duration of surgery and postoperative symptoms and signs.
Results.
No significant difference was found between the
two flap designs for any postoperative symptoms and signs. The duration of
surgery was found to be correlated with both trismus (r = -0.44, P = 0.04)
and swelling (r = 0.59, P = 0.004) as assessed 2 days after surgery. No
associations were found between duration of surgery and maximum postoperative
pain and trismus and swelling at 7-day interval.
Conclusion.
Within
the limits of the present study, the duration of surgery, and not the flap
design, affected the acute
postoperative symptoms and signs after lower third molar extraction.
IBS patients had a more than three times greater risk of TMD compared to HC. 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
