摘要:

AbstractThe clinical potential of the tunnel restoration is restrained by perceived difficulties of access to proximal caries and lack of long‐term clinical data.This paper describes a technique that affords proximal access similar to that of a standard Class II cavity preparation and provides an evaluation of a technique, using capsulated glass ionomer cements. It is supported by more than nine years of clinical experience that confirms the viability of this procedure as an alternative to conventional Class II cavity restorations for initial proximal lesion

摘要:

AbstractThe inferior dental and lingual nerves are in close proximity to the mandibular third molar. In approximately 5 per cent of cases of the surgical removal of this tooth one or other of these nerves may be injured. In most cases the injury is reversible but in 1 per cent a distressing dysaesthesia may occur. The diagnosis of the sensory deficit is made by repeated sensory testing. If there is no improvement by six to nine months then complete spontaneous recovery will not occur. These irreversible nerve injuries can be successfully treated microsurgically.

摘要:

AbstractFacial palsy is a relatively uncommon condition with a variety of causes including dental intervention. A brief history of two cases of facial palsy with dental implications is presented. The aetiology of facial palsy is reviewed and the management of such cases is discussed. The option of immediate treatment of Bell's palsy with prednisone is stressed.

摘要:

AbstractThis study compared the efficacy of EMLA 5% Cream, Xylocaine 5% (lignocaine 5 per cent) and NUM (benzocaine 15 per cent, amethocaine 1.7 per cent) to a placebo in reducing the pain experience during needle insertion. In a random, double blind study three groups of twenty volunteers each had a paired topical anaesthetic/placebo placed bilaterally in the buccal sulcus of the upper premolar regions for two minutes, followed by the insertion of a standard 27 gauge needle to a depth of 5 mm. Pain experience was measured with visual analogue scales. Results showed that all three agents significantly reduced pain when compared with the placebo — EMLA (p<0.002); Xylocaine (p<0.05); NUM (p<0.005

摘要:

AbstractBecause of conflicting published data, the temperature rise in four elastomeric materials was measured with a thermistor during setting in the oral cavity and in metal and plastic moulds of varying shapes and volumes for ‘elastic set’ specimens. The clinical temperature rise was 2–3°C higher in the molar region than anteriorly, except for the polysiloxane. The temperature range attained in the set materials varied from 29°C to nearly 35°C for clinical andin vitrospecimens.The average time taken by a group of operators to remove this type of impression from the mouth was five seconds. In a custom tray with light and heavy viscosity materials, the syringe material layer was only 0–0.15 mm thick and, essentially, the heavy viscosity material provided the elastic components for the

摘要:

AbstractPrevious work1has presented a study of the mechanical properties of denture base resins reinforced with a new type of high performance fibre. It is now shown that the substantial improvements demonstrated in those composites remain largely unaffected by a watery environment, anatomical notches, moulding pressure and other factors of denture construction.The understanding of the reinforced resins is here complemented with a detailed study of the interface strength, taking into account the various couplings occurring within the system.

摘要:

AbstractData on dentists' choice of toothbrush brand/type for personal use and their recommendations for patients were obtained by means of a questionnaire. Seventy‐nine per cent of dentists surveyed received free samples, with Oral‐B comprising 33 per cent of all such samples, followed by Colgate (16 per cent) and Tek (13 per cent). Fifty‐three per cent of dentists surveyed indicated they used all free samples received. Sixty‐two per cent of dentists do not consider that different brushes differ significantly in their plaque‐removing ability. Therefore, while an effective toothbrushing technique is important, selection of the ‘correct toothbrush’ from the wide range available may not be critical. The results of the present investigation provide information that is relevant to dental health education and can be applied at the chairside as well as at the broader co

摘要:

AbstractA survey of attendance at continuing dental education courses convened by the University Postgraduate Dental Education Committee, University of Western Australia, and the Australian Dental Association. Western Australian Branch was collated for one calendar year. Attendances were compared relating to the number of dentists registered in the State, ADA membership, metropolitan versus rural dentists and the number of courses attended. The mandatory and voluntary options for continuing dental education are discussed in the light of the survey findings.
