    Notes: Abstract Effects of separate traits of malocclusion on concern for dental appearance were isolated by means of multiple regression analysis in a 15-yr follow-up study of 30-yr-old Danes. On the basis of questionnaires (response rate 86%, n= 841), the dependent “concern-for-dental-appearance” variable was constructed from the respondents' replies about recalled perceptions and societal reactions concerning their dental appearance at the time of adolescence. In the same individuals, separate traits of malocclusion had been recorded clinically 15 yr earlier. These traits were inserted as independent dummy variables into the regression model. In both sexes the closest relationship with the dependent variable was displayed by the most conspicuous traits in the anterior region of the dentition. Some traits showed significant associations only in women, whose regression coefficients were, in general, higher than those of men. About half of the variation in the dependent variable was explained by the model.

    Notes: Orthodontic treatment need has been assessed on the basis of complete orthodontic records in a random sample of 293 Danish children aged 13–17 years by a group of postgraduate orthodontic students and by three orthodontists. The estimates of treatment need ranged from 45 % to 61 %. Interexaminer agreement in pairs was observed in 77 %– 92 % (mean 83 %) of the cases. Uniformity in four individual assessments was reached in 69 % of the cases: 38 % were considered in need of treatment and 31 % were considered not to present such need; conversely, 31 % gave rise to disagreement. It is argued that, at present, the orthodontist's subjective estimate of treatment need probably constitutes a more realistic approach to the problem of assigning treatment priority than the various indices of malocclusion.

    Notes: Abstract – It was the aim to study orthodontic treatment experience and past and present perceived need for treatment in 30-year-old Danes who, at adolescence, had no access to organized orthodontic care. In order to identify the malocclusion traits which elicited treatment or need for treatment, the findings were related to the occurrence of various I rails which had been registered in the same individuals 15 years earlier. From questionnaires (response rate 86%, n= 841) it appeared I hat 10% had received treatment and 20% perceived need for treatment either in childhood or at present. At adolescence, the subjects who had subsequently received treatment, displayed relatively high frequencies of ectopic eruption, anterior cross-bite, extreme maxillary overjet, deep bile, and crowding; among those who perceived need for treatment, extreme maxillary overjet, mandibular overjet and crowding were relatively prevalent.

    Notes: Histologic examination of muscle biopsies and functional examination comprising electromyography and force measurements in a 19-yr-old boy with muscular dystrophy showed different wasting patterns of mandibular elevator and depressor muscles. Pronounced histopathologic changes were present in the masseter muscle, whereas pathologic findings in the anterior digastric muscle were limited to increased number of cells in slightly enlarged interfiber connective tissue. The masticatory pattern was distorted, and strength of mandibular elevator muscles was less than one third of the norm, whereas depressor strength corresponded more to reference values. This difference of muscular wasting might be caused by protective enzymes in the digastric muscle and/or functionally induced damage of the masseter. As affection from muscular dystrophy may vary greatly between the masticatory muscles, structural and functional examination should be used routinely to clarify prognosis before initiation of treatment procedures.

    Notes: The purpose of the present investigation was to describe the formation, maturation and eruption of the dentition, including supernumerary teeth in a sample of patients with cleidocranial dysplasia. The dentition was evaluated from orthopantomograms, intraoral radiographs, cephalometric films, surgically removed teeth and intraoral photographs in 19 patients (9 men, 10 women), aged 3.5 to 34 years. Formation of primary teeth was normal, whereas all patients but one had supernumerary permanent teeth. Frequency of supernumerary teeth ranged from 22% in the maxillary incisor region to 5% in the molar regions. Supernumerary teeth were formed lingually and occlusally to the normal teeth. Maturation of the primary dentition was normal, while permanent teeth were delayed from 1 to 4 yr. Supernumerary teeth were delayed about 4 years in relation to normal permanent teeth. Eruption of primary teeth was normal, whereas all patients had severe eruption problems of permanent teeth. It was hypothesized that the dental lamina for both primary and permanent dentition is normal, but does not resolve completely and therefore may form supernumerary teeth. Abnormalities of tooth morphology is related to inadequate space and arrested eruption. Delayed or arrested eruption is probably caused by diminished resorption of bone and of primary teeth and to the presence of multiple supernumerary teeth.
