[Contact dermatitis due to professional activity among dental health care personnel].

A questionnaire related to occupational health problems was mailed to 800 participants at the annual meeting of the Norwegian Dental Association in 1987. 259 persons completed the questionnaire. During the last year 82 respondents had experienced dermatoses on their hands or face for variable periods. Of this group, 51 were disturbed by the dermatoses and 15 had attended a doctor. The most prevalent reasons for the dermatoses were frequent hand washing and detergents, and the use of rubber gloves. Seventy-nine percent of all respondents routinely used gloves while treating patients. A weak relationship was observed between certain dental materials or working procedures, and the topography and characteristic of the dermatoses.

Cavity designs for class II amalgam restorations. A literature review and a suggested system for evaluation.

A classification system for variations in cavity design and finish has been developed for application on models of teeth with class II cavities for amalgam restorations. The system was based on a review of the literature, on principles for clinical studies, and on examination of models of 623 teeth in which routine class II cavity preparations had been made. Preliminary data on the agreement of rating of evaluators indicated that the classification system can be used with good consistency for assessment of variations in cavity preparations. Longitudinal clinical studies on the performance of restorations will be decisive for the validity of the selected criteria and for a relevant differentiation between acceptable and unacceptable preparation features.

Quality assessment of randomized controlled trials of oral implants.

The aim of this study was to assess the quality of randomized controlled trials (RCTs) concerned with the effectiveness of oral implants and to create a trial register. A multilayered search strategy was used to identify all RCTs published by the end of 1999 in any language. The Cochrane Oral Health Group specialist register, PubMed, and personal libraries were searched. Seventy-four RCTs were identified. Forty-three articles, not presenting the same patient material, were independently assessed by 3 researchers using a specially designed form. A statistician assessed all trials for the appropriateness of statistics. The quality of each study was assessed on 7 items, including 3 key domains. Randomization and concealment allocation procedures were not described in 30 articles (70%). Reasons for withdrawals were not given in 10 reports (23%). No attempt at blinding was reported in 31 studies (72%). The quality of RCTs of oral implants is generally poor and needs to be improved.

Chewing movements in TMD patients and a control group before and after use of a stabilization splint.

PURPOSE: This study assessed the effect of using an occlusal stabilization splint in the maxilla for 6 weeks on certain parameters of chewing movements in subjects with and without temporomandibular disorder symptoms. MATERIALS AND METHODS: Twelve male and 30 female temporomandibular disorder patients with and without a prior whiplash incidence, and individuals without signs and symptoms of temporomandibular disorders participated. The participants formed three groups matched according to gender and age (n = 3 x 14). A maxillary stabilization splint was used during sleep for 6 weeks. An optoelectronic system (MacReflex, Qualisys) was used to record chewing movements at baseline, before using the splint, and after 6-weeks' use of the splint. Calculated parameters were the duration of the chewing cycles, the spatial displacement, and the mean velocity of the mandible while chewing paraffin wax for 20 seconds. RESULTS: On a group basis, the use of an occlusal stabilization splint for 6 weeks did not change the jaw movement parameters in a predictable pattern as recorded under the conditions of this study. On an intraindividual basis, large variations in changes of chewing parameters over time were observed. CONCLUSION: The use of an occlusal stabilization splint for 6 weeks did not alter the jaw movements when chewing a substance with a soft consistency.

A definition of prosthetic dentistry.

PURPOSE: A more precise and up-to-date definition of prosthetic dentistry is warranted. The aim of the present review is to present a new core definition of the discipline on the basis of a discussion of existing definitions. MATERIALS AND METHODS: Clinical textbooks in prosthetic dentistry and dental implantology, as well as medical and dental glossaries were reviewed. RESULTS: Two main categories of definitions of prosthetic dentistry were identified: first, definitions that emphasized the technologic aspects of the discipline, i.e., the fabrication of prostheses; and second, definitions that incorporated some reference to the objectives or aims of prosthetic treatment, i.e., the restoration of one or more aspects of oral function. Slightly more than half of the citations contained such aim-related references, and this aspect tended to be most pronounced in recent publications. CONCLUSION: The following definition is ventured: prosthodontics is the discipline of dentistry concerned with the consequences of congenital absence or acquired loss of oral tissues and with the methods for and assessment whether more good than harm is done by inserting artificial devices made from alloplastic materials.
