AbstractSwallowing and aspiration of dental foreign objects is often reported in the literature. Swallowing seems to be more common than aspiration, and is observed most often in the elderly. Too often the size and configuration of these objects compounds their impaction and removal. A 67‐year‐old man swallowed a unilateral removable partial denture which became lodged in his mid‐oesophagus. The denture was located by radiographic examination of his chest and removal by a rigid oesophagoscopy was performed under general anaest

摘要:

AbstractA 29‐year‐old Caucasian woman who presented with short stature and multiple unerupted supernumerary teeth is described. Radiological investigations of her cranial and skeletal abnormalities revealed cleidocranial dysplasia. Because of the advanced age of the patient and contraindication for orthodontic treatment, only surgical and prosthetic treatment were performed. The characteristics and treatments of this rare autosomal dominant disorder are discus

摘要:

AbstractPrevious work has shown that variations exist amongst general dental practitioners in the volume and type of orthodontic services provided, the type of orthodontic appliances used, and the objectives of the orthodontic treatment. The aims of this survey were to identify practitioner characteristics that account for variations in the level of orthodontic services provided and which distinguish providers and non‐providers of orthodontic services. Multiple regression analysis revealed that four practitioner characteristics explained 41 per cent of the variance in the number of orthodontic patients treated. Dentists who treated more orthodontic patients: 1) treated more general practice patients; 2) frequently used multiple sources to keep up to date in orthodontics; 3) perceived their patient base to contain more children; and 4) were likely to have attended a Truitt course. Eleven variables best distinguished providers from non‐providers of orthodontic treatment; 1, 2 and 3 above had the highest correlation with the discriminant function. The Null Hypothesis that selected characteristics of dentists providing orthodontic services were no different from those of dentists not providing orthodontic services was rejected. The provision of orthodontic services was associated with a higher level of continuing orthodontic education as well as treating more general practice patients, especially child

摘要:

AbstractThe short‐term (6 weeks postoperative) and long‐term (12 months postoperative) horizontal skeletal stability of combined maxillary and mandibular advancement was evaluated by cephalometric analysis of 15 patients.The mean horizontal advancement of the maxilla was 5.84 mm. Six weeks later a mean horizontal relapse of 0.03 mm (0.05%) was identified. The mean horizontal relapse at long‐term follow‐up was 0.59 mm (10.1%).The mean horizontal advancement of the mandible was 12.35 mm at menton and 12.65 mm at pogonion. At 6 weeks, mean horizontal relapse, respectively at the above landmarks, was 0.11 mm and 0.21 mm (1.3%). The mean horizontal relapse at long‐term follow‐up was 2.19 mm and 1.98 mm (16.6%) respectively for the same landmarks.Subjectively and objectively, improvements were seen in facial aesthetics and dental occlusion. The results indicate that rigid fixation of osteotomies undertaken to correct ‘horizontal facial deficiency’ is a surgically predictable and relatively stable procedure when reviewed up to 12 month

摘要:

AbstractThere are many treatment modalities for temporomandibular disorders (TMD), most of which are effective in controlling symptoms, at least in the short term. The non‐surgical treatment of temporomandibular disorders continues to be the most effective way of managing over 80 per cent of patients who present with symptoms of temporomandibular pain and dysfunction. In this, the second article in the series, a general overview of the current non‐surgical treatment strategies for TMD will be presen

摘要:

AbstractAn investigation was carried out into the problems experienced by 114 referred patients with complete dentures who were considered to be difficult or to have difficult prosthodontic problems. The commonest problems were those of pain and lack of retention, due mainly to occlusal discrepancies and excessive VDO. Treatment was carried out on an individual basis with a large proportion of dentures being remade. However, a small number was satisfied by counselling alone without procedural treatment. A diagnostic denture technique was used for particularly difficult cases. This technique showed that, in two cases, technical prosthodontic inadequacies could definitively be excluded as the problem. The overall success rate for treatment was 80 per cent. Further studies on a larger patient sample are needed so that specific problems can be linked to cause and outcome in a meaningful manner.

AbstractA cephalometric study using Downs' analysis was undertaken with lateral cephalometric radiographs for a mixed sample of 50 child, adolescent and young adult Indonesians who presented with Angle Class I occlusions.Significant differences between this study group and the published results from comparative racial types were found for Downs' angle of convexity, Y‐axis and incisor inclinations, indicating that Indonesians can be differentiated from other races with similar occlusions by using Downs' analysi

摘要:

AbstractPrevious studies into sporting mouthguards have been mainly attitudinal or epidemiological. The aim of the present study was to build an impact rig to measure the impact absorbed by mouthguard materials of various thicknesses. The acceleration of the pendulum of the rig was measured and used to calculate the force transmitted to the materials.Impact tests were also performed on three commercially available mouthguard materials. Tests showed that the force transmitted through mouthguard materials was inversely related to the material thickness.Mouthguard construction techniques with ethylene vinyl acetate (EVA) plastics should be monitored to avoid occlusal thinning especially on the incisal edges. Thinning results in reduction in the protection offered by the mouthguard.

摘要:

AbstractIn 1987 all non‐specialist ADA member private practitioners in Queensland were invited to participate in a survey to determine the number of the various types of permanent restorations placed in one week and the percentage breakdown of the time they devoted to the various areas of dentistry. Results of that survey were published in 1989. The survey with a few minor changes was repeated in 1992. Results show that there has been little change in the pattern of practice over the five years with restorative dentistry still taking a very large proportion of respondents' time and similar materials being used. The dental workforce appears to be relatively stable with low rates of overseas and interstate migration. There is evidence of an increasing number of women dentists in the workforce and this is emphasized by a breakdown of the current undergraduate enrolmen
