- OBJECTIVE: To answer the question whether temporomandibular disorders (TMD) were more common in a group of individuals referred for orthognathic surgery than in a control group. The null hypothesis was that neither the frequency of signs and symptoms of TMD or diagnosed TMD would differ between the patient group and a control group. MATERIALS AND METHODS: A sample of 121 consecutive patients referred for orthognathic surgery at the Department of Oral Maxillofacial Surgery, Malmö University Hospital, Sweden, was interviewed and examined regarding signs and symptoms of TMD and headaches. A control group was formed by 56 age- and gender-matched individuals attending the Department of Oral Diagnosis, Faculty of Odontology, Malmö University, Sweden, and Public Dental Health Clinic in Oxie, County of Skane, Sweden. TMD diagnoses were used according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). RESULTS: The patient group showed more myofascial pain without limited opening, disc displacement with reduction, and arthralgia according to RDC/TMD than the control group. The patient group also had more symptoms and signs of TMD in general. CONCLUSIONS: The null hypothesis was rejected because patients who were to be treated with orthognathic surgery had more signs and symptoms of TMD and higher frequency of diagnosed TMD compared with the matched control group.

- OBJECTIVE: To test the null hypothesis that there is no difference between the craniofacial morphology of prematurely born children and that of matched full-term born controls. MATERIALS AND METHODS: White children 8 to 10 years of age, born at the University Hospitals of Lund and Malmö and living in the same part of Sweden, were included. One group consisted of 36 very preterm children, born during gestational weeks 29 to 32; the other group included 36 extremely preterm children, who were born before the 29th gestational week. Subjects were compared with a control group of 31 full-term children, who were matched for gender, age, nationality, and living area. One lateral head radiograph was taken for each child, and the cephalometric analysis included 15 angular and 11 linear variables. Also, the height, weight, and head circumference of each child were registered. RESULTS: A significantly shorter anterior cranial base and a less convex skeletal profile were found among extremely preterm children, and significantly shorter maxillary length was noted in both extremely preterm and very preterm groups as compared with full-term children. The lower incisors were significantly more retroclined and retruded in the extremely preterm group compared with the very preterm group and the full-term control group. Extremely preterm children were significantly shorter, and both extremely preterm and very preterm children had significantly lower weight and smaller head circumference compared with full-term children. CONCLUSION: The null hypothesis was rejected because several craniofacial parameters differed significantly between preterm and full-term born control children.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To evaluate mandibular function, signs, and symptoms of temporomandibular disorders (TMDs) and headache in prematurely born 8- to 10-year-old children, and to compare the findings with matched full-term born controls. MATERIAL AND METHODS: Seventy-three preterm children were selected from the Medical Birth Register--one group comprising 36 extremely preterm children born before the 29th gestational week, the other group 37 very preterm children born during gestational weeks 29 to 32. The preterm children were compared with a control group of 41 full-term children matched for gender, age, nationality, and living area. The subjective symptoms of TMD and headache were registered using a questionnaire. Mandibular function, signs, and symptoms of TMD and headache were registered. TMD diagnoses were set per Research Diagnostic Criteria for temporomandibular disorders (RDC/TMD). RESULTS: No significant differences between groups or gender were found for TMD diagnoses according to RDC/TMD or for headache. The preterm children had smaller mandibular movement capacity than the full-term control group, but when adjusting for weight, height, and head circumference mostly all group differences disappeared. CONCLUSIONS: Prematurely born children of 8 to 10 years of age did not differ from full-term born children when considering diagnoses according to RDC/TMD, signs, and symptoms of TMD or headache.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Aim: To compare and evaluate long-term stability of crossbite correction with Quad Helix or expansion plate in the mixed dentition. Methods: In this RCT-study 35 patients with unilateral posterior crossbite were randomized to be treated with either Quad Helix or expansion plate. The inclusion criteria were: mixed dentition, unilateral posterior crossbite, no sucking habits or previous orthodontic treatment. Stability was evaluated after 3 years by study cast measurements. Twenty subjects with normal occlusion were included as controls. Success rate, maxillary and mandibular transverse dimensions, overjet and overbite were registered. Results: Stability was equal for the two treatment methods. Small, albeit significant, differences between the groups were assessed with reference to transverse dimensions. No significant difference was seen for overjet and overbite. Conclusions: The long-term stability of posterior crossbite correction with Quad helix and expansion plate was equal.
