Poor sleep quality is commonly reported by patients with chronic pain, including temporomandibular disorders (TMD). The objectives of the study were to explore the relationship among sleep quality, perceived pain, and psychological stress of patients with TMD. A total of 137 consecutive TMD patients (13 men, 124 women; age range, 18 to 70 years) were examined and classified on the basis of results obtained. Approximately half (49.6%) were classified as having myofascial pain, 11.7% had internal derangement, 9.5% had capsulitis/synovitis, 10.2% had osteoarthritis/osteoarthrosis, and 19% had other pain, which included a broader variety of TMD-related diagnoses such as neuropathic pain or burning mouth syndrome. The average pain rating was 6.9 on a 10-point scale, and the average duration of the pain was 50.2 months. The Pittsburgh Sleep Quality Index was used to measure sleep quality. The Multidimensional Pain Inventory was used to evaluate the number of pain-related constructs, and the Revised System Checklist-90 self-report inventory was used to evaluate psychological symptoms. The study clearly demonstrated a positive relationship between sleep disturbance and perceived pain severity for TMD patients. The results also showed a positive relationship between sleep disturbance and psychologic symptomatology in these patients. The study confirms the frequent co-occurrence of reported sleep disturbance, subjective pain intensity, and psychological distress in patients with chronic TMD. The results suggest that sleep quality might be an important treatment target to address when managing chronic pain.

Craniofacial differences between Japanese and British Caucasian females with a skeletal Class III malocclusion N. Ishii, T. Deguchi, and N. P. Hunt. European Journal of Orthodontics 2002;24:493-9
Although the prevalence of Class III malocclusions is reported to differ by race, only a few studies have examined the morphological differences between Japanese and white people with Class III malocclusions. The aim of the study was to clarify the differences in craniofacial morphology of the 2 racial groups. Pretreatment lateral cephalometric radiographs of 28 Japanese and 24 white British women diagnosed with skeletal Class III malocclusion and scheduled for orthognathic surgery were examined. The Japanese women had a significantly shorter anterior cranial base, a significantly more obtuse gonial angle, a high-angle facial pattern with significantly increased lower facial height, and significantly more inclined maxillary incisors. There was no difference in mandibular dimensions between the Japanese and white groups. The reduced anterior cranial base and the midfacial component, together with the high-angle facial pattern in the Japanese group, would seem to translate to less favorable prospects for correcting a skeletal Class III pattern than in white people.

Proportional changes in cephalometric distances during Twin Block appliance therapy M. J. Trenouth European Journal of Orthodontics 2002;24:484-91
A number of authors have reported the outcome of Twin-block appliance therapy using angular and linear measurements. Size is independent of shape because an object can vary in size but retain its shape. The aim of this study was to investigate the cephalometric changes produced by the Twinblock appliance with differential percentage change in linear dimensions to assess alterations in shape. The sample for the retrospective study included pretreatment and posttreatment
