These findings should however be confirmed in a larger sample with migraine, tension-type headache, and trigeminal neuralgia.

To compare the prevalence of facial pain and headache across various regions in Sweden.

This study involved a comparison of cross-sectional questionnaire studies over a period of 10 years including 128,193 individuals and assessed facial pain, pain on function, and headache. Participants included (1) all Public Dental Service patients aged 16 to 90 years in Västerbotten (n = 57,283) and Gävleborg (n = 60,900); and (2) random samples of residents in Kalmar (n = 3,560) and Skåne (n = 6,450). selleck chemical Facial pain and pain on function were assessed for all participants, and headache was also assessed for participants in Kalmar and Skåne. Descriptive statistics were used to estimate unadjusted prevalence estimates and demographic characteristics. Prevalence estimates were adjusted for age and sex using weighted distributions from the 2015 data in the Swedish population registry before comparisons across the regions.

Overall, the prevalence of facial pain and headache were significantly higher in female than in male participants (P < .01). The standardized prevalence of facial pain was 4.9% in Västerbotten, 1.4% in Gävleborg, 4.6% in Kalmar, and 7.6% in Skåne. For headache, the standardized prevalence was 18.9% in Kalmar and 21.3% in Skåne. In Skåne, individuals with facial pain had a 15-fold higher odds of headache than those without.

In the present Swedish epidemiologic study, the prevalence of facial pain ranged from 1.4% in Gävleborg to 7.6% in Skåne. Besides different sampling frames and other population characteristics, the presence of a high number of immigrants in Skåne may account for some differences in pain prevalence across the Swedish regions.

To answer the question among observational studies, is there any association between primary headaches and bruxism in adults?

A systematic review of observational studies was performed. The search was performed in seven main databases and three gray literature databases. Studies in which samples were composed of adult patients were included. Primary headaches were required to be diagnosed by the International Classification of Headache Disorders. Any diagnostic method for bruxism was accepted. Risk of bias was evaluated using the Joanna Briggs Institute Critical Appraisal Tool and the Meta-Analysis of Statistics Assessment and Review Instrument (MAStARI) tool. Associations were analyzed by calculating odds ratios (OR) in Review Manager 5.3 software. The evidence certainty was screened by Grading of Recommendations Assessment, Development, and Evaluation criteria.

Of the 544 articles reviewed, 5 met the inclusion criteria for qualitative analysis. The included studies evaluated both awake and sleep bruxintroversial.

To analyze Axis I and II findings of patients diagnosed as having painful temporomandibular disorder (TMD) with headache attributed to TMD (HAattrTMD) in order to assess whether HAattrTMD is associated with a specific Axis I and II profile suggestive of the central sensitization process.

This retrospective study included 220 patients with painful TMD divided into those with (n = 60) and those without (n = 160) HAattrTMD, and the patients were compared for Axis I and II results according to the Diagnostic Criteria for TMD (DC/TMD). A P value < .05 was considered statistically significant.

A total of 27.3% of the patients received a diagnosis of HAattrTMD. Myofascial pain with referral was significantly more common in the HAattrTMD group (P < .001), while local myalgia was significantly more common in the non-HAattrTMD group (P < .001). Characteristic pain intensity was significantly higher in the HAattrTMD group (P = .003), which also showed significantly higher levels of depression (P = .002), nonspecific physical symptoms (P = .004), graded chronic pain (P = .008), and pain catastrophizing (P = .013). Nonspecific physical symptoms were positively associated with HAattrTMD (odds ratio [OR] = 1.098, 95% CI = 1.006 to 1.200, P = .037). Local myalgia was negatively associated with HAattrTMD (OR = .295, 95% CI = 0.098 to 0.887, P = .030).

Painful TMD patients who report headache in the temple area and are diagnosed as having local myalgia rather than myofascial pain with referral probably do not have HAattrTMD. The diagnosis of HAattrTMD may point to a central sensitization process and possible current/future chronic TMD conditions.

To report the effectiveness of temporomandibular joint (TMJ) arthrocentesis with viscosupplementation for degenerative joint disease (DJD) over a long-term (ie, 10-22 years) follow-up.

A total of 103 patients aged between 30 and 91 years (13 men and 90 women; mean age 63.7 years) who received a cycle of five arthrocentesis sessions with HA viscosupplementation to manage their symptoms related to TMJ DJD during the time period from 1998 to 2010 were recalled for clinical evaluation. After the treatment cycle, clinical outcomes were assessed based on the following parameters maximum mouth opening (MO), pain with function (PF), pain at rest (PR), and self-reported chewing efficiency (CE). Data were collected at baseline (T

) and at successive follow-up assessments, after at least 3 months (T

) and 1 year (T

), as per previous publications. Patients who had received treatment at least 10 years prior were then recalled for this study (T

10 to 22 years follow-up). Analysis of variance for repeated measures was performed to assess changes over time.
