High prevalence of orofacial pain in juvenile fibromyalgia as detected by a novel tool specifically devised for children and adolescents
Authors' conclusion
TMJ hypermobility, in addition to orofacial and masticatory muscle pain, is an important clue for the diagnosis of TMD in adolescents with JFS.
Study context
- Population
- Children and adolescents with juvenile fibromyalgia syndrome (median age 15.5 years) and healthy controls (median age 15.0 years)
- Participants
- 30 vs 45
- Exposure
- Juvenile fibromyalgia syndrome (JFS) vs healthy controls
- JFSn = 30
- Controlsn = 45reference
- Outcome
- Prevalence of temporomandibular disorders (TMD) (signs and symptoms assessed with a novel clinical tool for children: self-report questionnaire and orofacial clinical examination protocol)
Methodological detailsmultivariate logistic regression
- Multivariate logistic regression
Main finding
As reported in the abstract
Orofacial pain
P < 0.001
Observational data: associations, not effects.
Further findings
Pain on TMJ palpation
P < 0.001
| Outcome | OR | P value |
|---|---|---|
| TMD features independently associated with JFS (multiple regression)Spontaneous orofacial pain | 21.0 | P = 0.005 |
| TMD features independently associated with JFS (multiple regression)Diffuse tenderness on palpation of the masticatory muscles | 14.9 | P = 0.026 |
| TMD features independently associated with JFS (multiple regression)TMJ hypermobility | 1.42 | P = 0.008 |
Maximum spontaneous mouth opening, voluntary active opening and assisted passive opening (medians)
- Significantly higher in JFS than in controls
