The dentine-bonded ceramic crown: an ideal restoration?

The principles used in the bonding of porcelain veneers may also be applied to full-coverage restorations, with such crowns luted using resin-based materials. For these full coverage restorations, dentine bonding agents, preferably of low film thickness, may be used to treat areas of exposed dentine prior to placement. These 'dentine-bonded' all-ceramic crowns may exhibit many favourable characteristics, including those of good aesthetics and peripheral blend with gingival tissues and the potential for placement on conservative preparations which may minimise the risk of pulpal damage. Indications include cases in which conventional crowns require replacement, those in which minimal preparation techniques are appropriate, and those in which there has been tooth surface loss. Contraindications include subgingival margins, extreme occlusal interferences and insufficient tooth substance for bonding. However, the longevity of these restorations is, as yet, unknown, in the absence of long-term clinical data.

Occupational stress and dentistry: theory and practice. Part I. Recognition.

Dental practice has been considered to be the most stressful of the health care professions. Increasingly dentists in general practice seem to experience more physical and mental ill health compared with other health professionals and this has been recognised to be a consequence of occupational stress. Occupational stress has been related to changes in clinical dental practice with many of the perceived causes being within the dentist's own control. Since dentists are faced daily with these potential occupational stressors one way of controlling stress is through its recognition. This paper highlights experiences common to all those in dental practice as a first step in reducing occupational stress.

Occupational stress and dentistry: theory and practice. Part II. Assessment and control.

Since dentistry has been identified as being a stressful profession, dentists, with the help of the members of the dental team, must attempt to achieve a relatively stress-free working environment. In addition to recognising potential occupational stressors it is important for dentists to be able to assess their emotional responses to the practice of dentistry and to arrange their daily working lives in such a way as to reduce occupational stress. This paper examines the means by which dentists may assess occupational stress as well as person-centred and/or situation-centred strategies of coping with and controlling occupational stress in general dental practice.

Factors associated with dentists' willingness to treat high-risk patients.

The attitude of dentists in England and Wales to treatment of patients at high risk to HIV/HBV was tested by means of a postal questionnaire distributed to 1950 dentists randomly selected from those practising within the NHS Regulations. The response rate was 61%, with 52% of respondents indicating that they treated patients at high risk to AIDS/HBV. Analysis of respondent dentists' practice and personal profile showed associations between willingness to treat high-risk category patients and respondents' number of years since graduation, respondents' gender, number of postgraduate courses attended, and respondents' practice type.

Handpiece asepsis: a survey of the attitudes of dental practitioners.

The methods of handpiece asepsis employed by general dental practitioners (GDPs) in England and the problems considered to be associated with handpiece sterilisation were investigated by means of a postal questionnaire distributed to a random sample of 500 GDPs during July 1993. A total of 267 replies were received (53.4% response). The results indicated that at the time of the survey, autoclavable handpieces were possessed by 90.6% of the respondents (n = 242), with 45.9% (n = 111) of these respondents indicating that they autoclaved their handpieces routinely after every patient. Reasons given by respondents for not autoclaving handpieces routinely included insufficient handpieces, fear of handpiece damage, cost, and the consideration that sterilisation was not necessary. Handpiece asepsis procedures had been upgraded by 89% (n = 237) of respondents in the 5 years preceding the survey. Media coverage was found to have exerted influence on the respondent dentists' behaviour, with the overall incidence of routine handpiece autoclaving increasing by 20.6% after media coverage of the subject.

Factors associated with skin irritation of the hands experienced by general dental practitioners.

Practising dental surgeons are now wearing gloves for longer periods of time than any other comparable group. As part of a study to assess dentists' attitudes to cross-infection, a questionnaire was sent to 1950 randomly selected general dental practitioners in England and Wales, with information being requested concerning the incidence of skin irritation of the hands considered to be associated with glove wearing. The response to the questionnaire was 61%, with 29% of respondents indicating that they experienced skin irritation. A strong association was identified between pattern of glove wearing and incidence of skin irritation, with routine glove wearers being more likely to suffer skin irritation than occasional glove wearers. Female respondents were also more likely to have experienced skin irritation than male respondents. No association was identified between reported incidence of skin irritation and practising arrangements, years since graduation and number of years of glove wearing.

Indirect composite preparation width and depth and tooth fracture resistance.

PURPOSE: To evaluate the influence of preparation width and depth on the fracture resistance of teeth restored with one type of indirect composite restoration. MATERIALS AND METHODS: Variations of depth and width were superimposed on a preparation of dentin design and dimensions with other variables including tooth size and morphology being controlled. Indirect composite restorations were constructed and placed in accordance with manufacturer's instructions. The restored teeth were subjected to compressive loading with fracture being induced by application of a 4 mm steel rod to the specimens in a universal testing machine, at a cross-head speed of 1 mm/minute. RESULTS: Preparation depths of 3 to 4 mm were found to be preferable, but when the prevalence of severe tooth fracture was assessed, the shallower preparation depth was found to be indicated. Cavity depths of one-third and one-half bucco-lingual width were evaluated, the fracturing forces for the group with the narrower width being statistically lower.

The four generations of dentin bonding.

The achievement of an adhesive bond between enamel and dentin and restorative materials has been an objective for generations of dental research workers. Dentin bonding agents have been classified into generations, with earliest generations showing unreliable bond strengths. Some currently available systems show in vitro shear bond strengths to dentin which are similar to the bond strength to enamel, this being considered an ideal property. Alongside other previously recognized ideal properties, appropriate criteria for state-of-the-art dentin bonding systems at the present time may be considered to include the ability of systems to operate in moist environments and be technique insensitive.

The effect of variations in bonding procedure on fracture resistance of dentin-bonded all-ceramic crowns.

This in vitro study investigated the effect of dentinal bonding and ceramic etching procedures on the fracture resistance of all-ceramic crowns. These results were compared with the fracture resistance of similar crowns placed with a nonadhesive conventional cement. All results indicated that superior fracture resistance was obtained when dentinal bonding was incorporated into the luting procedure together with etching of the ceramic fitting surface and the use of resin-based luting material. The fracture resistance of specimens luted with such a procedure was significantly greater than that of specimens in which a conventional nonadhesive cement was used.

Glove use by dentists in England and Wales: results of a 2-year follow-up survey.

This paper reports the findings of a 2-year follow-up study of glove use by dentists practising within the NHS regulations in England and Wales. The questionnaire for this study was distributed in November/December 1991 to 1950 dentists. The response rate was 61.5%. Analysis of the data obtained from the replies indicated that 83% of respondents wore gloves routinely for all patients and all procedures, 15% wore gloves for either selected patients or procedures and 2% never wore gloves. Glove wearing patterns were found to be related to gender, practice type and frequency of attendance at postgraduate courses. Overall, the results indicate increasing levels of compliance with recommendations concerning glove wearing while treating patients.

A review of dental injuries and the use of mouthguards in contact team sports.

Dental injuries are the commonest type of orofacial injury sustained during participation in sports. Of the types which are currently available, custom-made mouthguards fitted by a dentist have been demonstrated to provide the greatest protection from dental injuries. Such mouthguards should therefore be recommended for use by those who participate in contact sports, and their provision should be actively encouraged by dental care workers.
