Abstracts of Current Research

The use of panoramic radiographs in the localization of an impacted canine. The objective was to develop a reliable method of diagnosing the position of displaced maxillary canines, based on a single panoramic x-ray. 113 panoramic radiographs including 160 displaced maxillary canines were evaluated. Ratios between the width of the displaced canine and (a) the homolateral central incisor (CII) and (b) the contralateral canine (CCI) were calculated. The height of the crown of each displaced canine was classified in the vertical plane, relative to the adjacent incisor as: apical, middle, and coronal. There was an overlap in the CII ranges of the buccal (0.94-1.45) and palatal (1.15-1.29) canines in the apical zone. In the middle and coronal zones a clear difference could be seen between the CII of labially (0.78-1.10) and palatally (1.15- 1.7) located canines. The cut-off point of 1.15 was determined. Provided the vertical restriction and CII are used, the panoramic radiograph can serve as a useful indicator for determining the position of unerupted maxillary canines.

Orthodontic treatment for disabled children: motivation, expectation and satisfaction.
The aim of the study was to examine motivation for and expectations of proposed orthodontic treatment for disabled children, among the parents and the children. Most of the patients presenting for orthodontic treatment, whose mean age was 12.9 years, lived with their parents. The parents, whose response rate in returning the questionnaire was 95.7 per cent, expected improvement in the child's appearance with a concomitant improvement in his/her social acceptance. The children mostly understood the reasons for treatment, in the most general of terms. The results indicate that parents of disabled children are highly motivated to improve their child's appearance, which was found to be unrelated to any improvement of their own perceived social standing. There is evidence to show that, in contrast to the principal area of the child's intractable disability, the parents seek to develop their child's potential to the full in an area where results are achievable. It is concluded that, as orthodontists, we are able to offer treatment to this minority sector of the child population and methods of gaining therapeutic access should be improved.

Dental age in maxillary canine ectopia. An etiologic connection between palatally-ectopic canines and small and missing teeth is well-established in the literature. Additionally, it has been observed that patients with palatally-ectopic canines have a delayed dental development. The present study was designed to examine the validity of this latter observation, by assessing the dental age of the subjects radiographically, using criteria of tooth calcification, rather than tooth eruption pattern. A similar determination was made in relation to subjects in whom buccally-ectopic canines were present. The experimental group consisted of panoramic radiographs of 55 consecutively-treated cases with palatally-displaced maxillary canines and 47 consecutively-treated cases with buccally-displaced canines. They were compared to a control group of 57 consecutively-treated cases with normally-placed canines. Approximately half the subjects with palatal displacement exhibited a late-developing dentition, while the timing of the remainder appeared to be normal. Buccal displacement was not associated with a retarded dental development and the ranges of the dental age values were similar to those seen in the control group. The results support the idea that there are different etiologies for the occurrence of buccal versus palatal ectopia in maxillary canines. They also suggest that dentitions with a palatal canine appear to be of two distinct varieties, with different dental characteristics and, perhaps, different etiologies.

The prevalence of tooth transposition, third molar agenesis and tooth impaction in individuals with Down syndrome.
Among the many inherited disorders, which have been reported in individuals with Down syndrome, are alterations in the size, morphology and number of teeth. By contrast, third molar agenesis and tooth transposition has been largely ignored and the prevalence of canine impaction has not been reported. It was the intention of this study to quantify the occurrence of these anomalies in a group of individuals with Down syndrome, using standardized records, which included clinical examination, dental casts and panoramic radiograph. The results show a notably high prevalence of third molar agenesis (74% of individuals older than 14 years), canine impaction (15%), and maxillary canine/first premolar transposition (15%), compared to published figures from random population samples. These anomalies should not be seen as separate, independent entities, but as associated phenomena. Alternatively, the slow rate of cell growth and a consequent reduced cell number which characterize this syndrome may be responsible for the underdevelopment of the upper jaw, the delayed dental development, the reduction in teeth number and size and the altered path of canines eruption. No explanation, other than genetics, is immediately available to explain why the maxillary canine/first premolar transposition should represent another phenotypic expression of this trisomy.
