摘要:

AbstractReports of oral lesions associated with cytomegalovirus (CMV) infection in human immunodeficiency virus (HIV) infected patients are uncommon1. In this article a case of CMV infection associated with oral mucosal ulceration and a brief review of the subject is presented. Establishing the cause of ulceration is important in determining a definitive diagnosis and prescribing appropriate therapy. It is important to recognize that CMV associated oral mucosal ulceration may be the initial manifestation of human immunodeficiency virus (HIV) infection.

摘要:

AbstractA case of an infected mandibular fracture is presented. A submandibular abscess appeared to arise from chronic pericoronal infection associated with a third molar tooth in the line of fracture. Treatment of the case is described followed by a short discussion on the aetiology and management of infected mandibular fractures. The importance of adequate first aid and prompt referral is stressed.

摘要:

AbstractThe measurement of blood pressure and pulse rate prior to, during and after exodontia was conducted on 60 healthy patients. The aims were to first, investigate the changes in blood pressure and pulse rate, and second, to observe the presence of any clinically significant change over time. Thirty patients attending an Oral Medicine Clinic were used as the control group to allow a comparison to be made between the effects of exodontia and non‐invasive treatment. The results suggested that exodontia was the most stressful part of the procedure. Bradycardia during local analgesia was also noted. These changes in the cardiovascular parameters may represent a risk to patients with heart diseases especially those previously undiagnosed. Further, the results indicate the effect stress can have on the cardiovascular system and the importance of eliminating pain and minimizing patient anxiet

摘要:

AbstractHemifacial microsomia is a rare dentofacial anomaly which is regarded as a separate entity to Goldenhar syndrome and primarily affects the structures of the first branchial arch. It has a heterogeneous aetiology and tends to occur sporadically, though positive family histories have been reported. This paper reports on individuals in two generations of a family that has overlapping features of hemifacial micro‐somia and Goldenhar syndrome segregating as an autosomal dominant conditio

摘要:

AbstractThe purpose of this study was to evaluate the effect of 10 per cent maleic and 37 per cent phosphoric acid on the shear bond strength of Z100 composite resin with Scotchbond Multi‐Purpose adhesive to primary and permanent tooth enamel. Four groups of 20 teeth each were established: 1, permanent teeth, 10 percent maleic acid etched for 15 seconds; 2, permanent teeth, 10 per cent maleic acid etched for 30 seconds; 3, permanent teeth, 37 per cent phosphoric acid etched for 15 seconds; 4, primary teeth, 10 per cent maleic acid etched for 15 seconds. Five teeth from each group were randomly assigned for SEM examination of the etched enamel surface. Scotchbond Multi‐Purpose primer and adhesive were applied to the etched enamel surface of the remaining 15 teeth and cured following the manufacturer's instructions. Z100 composite resin was placed in a nylon cylinder and cured for two 40 second intervals. Following thermocycling, the specimens were sheared on an universal testing machine and debonded areas were examined visually with a stereo microscope and with SEM. The mean shear bond strengths in MPa were: 1,17.00; 2, 14.58; 3, 14.66; 4, 11.18. ANOVA and Student‐Newman‐Keuls analyses revealed no statistically significant difference among the groups. SEM examination showed the majority of specimens fractured at the adhesive‐resin

摘要:

AbstractThe chemical composition, thermal behaviour and mechanical properties of three tooth positioner materials, Urethane P1 (P1), White Rubber (WR) and Elastocryl (EL) were investigated. Infra‐red spectrophotometry indicated the P1 polyurethane material to be of the polyether type, and EL to be a blend of poly(ethyl methacrylate) and poly(methyl methacrylate) while WR appeared to be filledcis‐poly (isoprene) (natural rubber). The glass transition temperature (Tg) for EL was determined as approximately 10deg;C, and for both P1 and WR the Tgwas less than ‐50deg;C. The stress relaxation behaviour was assessed in compression by measuring the stress variation with time. The results for all three materials conformed to the superelastic theory of rubber elasticity. EL exhibited both a more rapid rate and higher degree of stress relaxation than did P1 and WR. Recovery from deformation was assessed by compressing cylinders for given periods of time and then measuring the level of reduced residual strain of the material with time. All three materials exhibited significant residual strain (ɛ(t)) over ‘clinically relevant’ time periods, and the reduced residual strain (ɛ (t)/ ɛ (0)) following deformation was greater for EL than P1 or WR. There was some indication that the three materials have some permanent set following deformation. It was concluded that, in considering desirable mechanical properties of tooth positioner materials, EL is the least suitable of the three examined, with none of the materials

摘要:

AbstractA new concept of the plane of occlusion based on anatomical landmarks has been developed. The posterior end of the plane is set by the centres of the retromolar pads, and the anterior end of the plane is at the upper lip line. These three points establish the plane of occlusion. An articulator has been developed to use this concept, which has been found to be clinically satisfactory for the construction of complete dentures.

摘要:

AbstractTo a considerable extent, host factors condition the initiation and progression of periodontitis. The integrity of the periodontal structures and the immune elements in the gingival fluid may act as a defensive barrier against microorganisms. However, immune over‐response may lead to tissue damage and bone resorption from anaphylactic reactions, immunocomplex reactions, type IV hypersensitivity, complement hyperactivation via the alternative pathway, or direct action of leukocytes and macrophages. Moreover, insufficient host response allows bacteria to escape control, allowing more rapid progression of the diseas

摘要:

AbstractService‐mix can reflect changes in demographic factors, oral health, patient demand and treatment philosophies. The aim of this study was to compare service‐mix by patient age in 1988 with baseline data from 1983. A weighted, stratified random sample of dentists in Australia was surveyed by mailed questionnaire in 1983 and again in 1988. Service‐mix was dominated by restorative, diagnostic and preventive areas. Comparing 1988 with 1983, there were significant increases for diagnostic, preventive, advanced restorative, orthodontic and general areas. Patterns across patient age groups and between years indicated younger patients were being provided with increased preventive services (patients aged 5–11, 25–44 years) and decreased restorative services (patients aged 5–11, 12–17 years), while older patients were being provided with reduced prosthodontic services (patients aged 25–44, 45–64 years), but increased restorative services (patients aged 45–64, 65+ years) and advanced restorative services (patients aged 25–44, 45–64 years).These patterns of service‐mix have implications for dental education, rese
