Abstract

Objectives: We sought to study the long-term outcome of juvenile chronic arthritis (JCA) in the temporomandibular joint (TMJ). Study Design: Temporomandibular disorders, including TMJ involvement, were assessed in 42 women with pauciarticular or polyarticular JCA—on average 25.8 years from disease onset—and compared with those found in matched control subjects. Disease-related parameters associated with temporomandibular disorders were identified. Results: The TMJ was involved in 66.7% of the patients, most severely in extended pauciarticular JCA. Temporomandibular disorders were more frequent in the patients than in the control subjects, especially in those with persistent disease. The TMJ involvement was positively correlated with disease duration and negatively correlated with jaw opening and occlusal support. Duration of active JCA and history of functional pain were identified as predictors of present TMJ involvement. Conclusion: In a long-term follow-up, TMJ involvement proved frequent in the studied patients and was associated with long disease duration and previous pain on jaw opening. The findings suggest that patients with JCA should undergo orofacial evaluation on a regular basis. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2001;92:406-14)

Patients

In 1979 and 1980, Kreiborg et al4 and Pedersen et al18 performed a referral-based follow-up study of 93 patients with JCA admitted to the Hornbaek Hospital of Physical Medicine, Denmark, during the period from 1965 through 1977. From this group, 65 patients were followed up in 1996 and 1997.19 To secure homogeneity and to facilitate statistical evaluation, the relatively few male subjects and the few subjects with systemic JCA were excluded from the present report. Thus, only patients with

General condition of patients with JCA

The disease and its sequelae were most severe in the extended pauciarticular and polyarticular subtype of JCA (Table I). Twenty of the 43 participants had active JCA at the time of the study (47.6%). The general VAS pain scores ranged from 0 mm to 80 mm. Most patients had complete, or only mildly affected, functional ability (Steinbrocker functional class distribution I and II), but 3 patients (7.2%) had limited functional capacity or were largely or wholly incapacitated.

Discussion

The patients with JCA in the present study most likely represented those most in need of hospital care after disease onset, because the study population from the start was referral-based.19 However, even with this possible bias toward the more severe cases, the high frequency of persistent disease demonstrates that the general prognosis for pauciarticular and polyarticular JCA can be unfavorable.

The polyarticular course of the disease was associated with the most “poor” disease outcome, both in

Conclusion

The present long-term follow-up study confirms that TMJ involvement is a frequent manifestation in patients with JCA. A majority of the patients experienced increased morbidity of reduced opening and biting abilities and orofacial pain due to TMJ involvement. The severity of these symptoms and signs was associated with long JCA duration and previous pain on jaw opening. Our findings suggest that all patients with JCA should undergo regular orofacial evaluation and that optimal disease control

      From a total of 345 unique citations, 21 articles complied with the inclusion and exclusion criteria were therefore included (Figure). The reasons for excluding full-text reviewed articles were studies without measureable or objective outcome variables [37–41], dual publications with the exception of meta-analyses [2,42,43], studies including insufficient imaging/x-ray modalities [4,44–47], articles mainly reporting on JIA patients older than 20 years of age [5,7,48], and the use of clinical indices where no singular outcome measures can be extrapolated from a score [49]. Due to the heterogeneity of the study designs and patient populations reported in the literature, we decided to subdivide and describe the findings in relation to the following three categories: (1) patients referred to a radiologist and/or dentist for consultation on suspicion of TMJ arthritis [20–24,29,31,33], (2) cross-sectional patient groups [15,19,25–28,30,32,35], and (3) newly diagnosed JIA patients (inception cohort) [12–14,34].

      Karhulahti et al.43 studied 121 JRA patients who were 15 years old, finding condylar flattening in 65 (55%) as well as decreased oral aperture in patients compared to healthy 15-year-old children. Important findings in several of these and other studies is that the risk of TMJ arthritis evident by radiography increases with prolonged disease duration, consistent with a cumulative effect of unopposed inflammation.44,45 This was illustrated most dramatically by Larheim and colleagues, who re-evaluated 60 of the original 103 subjects at a mean follow-up of 27 years.46
