Dental time study results in relation to a model for a dental health related patient group system.

Using a time study method, dental care treatment resources were studied concerning different caries groups of children and adolescents 3-19 years of age. The results were applied to a model for a dental health related patient group system as a tool for presenting the dental care situation. Quality assurance aspects of a dental health related patient group system, adapted for use in general dental care, had led to a suggested model system: "Dental Visiting Groups" (DVG). The DVG system takes into consideration the fact that dental care was performed by three dental care-giving personnel groups--dentists, dental hygienists and dental assistants--giving dental care in three main areas of dental procedures: diagnostic, prevention and intervention. The DVG system implied a model of Swedish dentistry in change, and presented the relationships among the dental health related patient groups, the three main areas of dental procedures, and the tasks of the dental care-givers. Applied over time, the DVG system illustrated the efficiency of the dental care model used.

The dental scientist model.

A case has been presented for strengthening the science-base of the future dentist. Such a development is essential and inevitable and we must plan the changes in the dental education continuum that will facilitate it. Transfer of advanced clinical training to mandatory post-doctoral education will control the economic impact of the change and improve the education of the dentist tomorrow.

A proposed human needs conceptual model for dental hygiene: part I.

To date, research and theory development in dental hygiene have been largely sporadic and lacking in focus. Dental hygiene has begun to develop its body of knowledge by adopting a definition of the discipline and a structural hierarchy of knowledge that includes a global paradigm, conceptual model(s), and theory. By identifying major concepts and linking theory to an expanding knowledge base, dental hygiene can begin to evolve as a scientific discipline. Conceptual models and theories will characterize the uniqueness of dental hygiene and move it into collegiality with other professional disciplines. In the future, practitioners, educators, and researchers may adopt an organizational framework for dental hygiene. Doing so will enhance dental hygiene research, teaching, and client care. Most importantly, it will enhance dental hygiene's view of itself. This in turn will facilitate dental hygiene's continuing evolution toward professionalization.

Age-related changes in social and psychological models predicting dental care in children.

Social and psychological factors associated with dental care were examined in two groups of children ages 6-8 and 9-11 years. Level of surface plaque, measures of dental health status (that is, total number of primary teeth decayed, missing, and filled [dmft] and total number of permanent teeth decayed, missing, and filled [DMFT] ), and frequency of dental visits were used as indicators of preventive behavior. The importance of social and psychological factors associated with these indicators was shown to vary with age group and with the specific preventive behavior indicator. Perceived level of dental anxiety and dental vulnerability were significantly associated with dental care, with dental anxiety being an important factor only in the lower group. Accessibility to a free school dental service was an important predictor of dental health status (DMFT) in the older age group, however, the data indicate that only when this service was offered within an organized structure of referral and transport was there an optimal effect on subsequent dental health.

Measurement of arch widths in a human population: relation of anticipated bite marks.

The authors compared arch width measurements of diagnostic dental models obtained from dental school patients. Arch width measurements were taken in the canine area on each dental cast in an effort to assist forensic dental investigators in matching certain classes of subjects to the bites they might possibly inflict. If any canine teeth were absent, the measurements were taken using other specified adjacent teeth which the investigators felt would be interpreted as the arch width determiners in a bite mark injury. The ages of the subjects varied from 14 to 87 years. Statistical comparison of the maxillary arch width, mandibular arch width, and the mean difference between maxillary and mandibular arch width were performed. Significant differences between the arch width measurements were found to exist between several classes of subjects based on race and sex.

A national econometric forecasting model of the dental sector.

The Econometric Model of the the Dental Sector forecasts a broad range of dental sector variables, including dental care prices; the amount of care produced and consumed; employment of hygienists, dental assistants, and clericals; hours worked by dentists; dental incomes; and number of dentists. These forecasts are based upon values specified by the user for the various factors which help determine the supply an demand for dental care, such as the size of the population, per capita income, the proportion of the population covered by private dental insurance, the cost of hiring clericals and dental assistants, and relevant government policies. In a test of its reliability, the model forecast dental sector behavior quite accurately for the period 1971 through 1977.

A genetic model of dental reduction through the probable mutation effect.

A simulation approach is used in order to elucidate the nature of the hypothesized "probable mutation effect" as it applies to dental reduction in man. Computer-generated simulations of the accumulation of mutations in a human gene pool show the results of the proposed model under the influence of various parameters, as well as illustrating the nature of such genetic change through time. This approach supports a polygenic model of the probable mutation effect as a viable hypothesis for an explanation of the dental reduction which has occurred in some human populations over the last 40,000 years.

A comparison of 3 methods of face-bow transfer recording: implications for orthognathic surgery.

PURPOSE: The purpose of this study was to compare the occlusal plane inclination of models mounted using 3 different systems for face-bow transfer with the actual occlusal plane inclination as measured on a cephalometric radiograph. PATIENTS AND METHODS: Twenty-two subjects were enrolled in this study. Three alginate impressions of the maxillary dentition were taken, and 3 stone dental models were produced for each subject. Face-bow recordings were obtained on each subject using the SAM Anatomical Face-bow (Great Lakes Orthodontics Products, Ltd, Tonawanda, NY), the Erickson Surgical Face-bow (Great Lakes Orthodontics Products, Ltd) and a new technique developed by one of the authors (J.G.). For each subject, the dental models were mounted on a SAM articulator using each of the 3 face-bow recordings. Finally, a lateral cephalometric radiograph was obtained for each subject. The occlusal plane inclination was measured on the models and on the cephalometric radiographs. Differences among groups were tested using a 1-way analysis of variance. Bonferroni test was used for post hoc comparison between different pairs of groups. RESULTS: The average occlusal plane inclination using the SAM Anatomical Face-bow was 7.8 degrees +/- 4.2 degrees greater than the actual-a difference that was statistically significant. The mean occlusal plane inclination of the models obtained using the Erickson Surgical Face-bow was 4.4 degrees +/- 2.2 degrees greater than the actual-a difference that was also statistically significant. The mean occlusal plane inclination of the models obtained by the new technique was only 0.9 degrees +/- 1.2 degrees greater than the actual; this difference was not statistically significant. CONCLUSIONS: The new mounting technique is more accurate than the conventional SAM Face-bow or the Erickson Face-bow for reproducing the actual occlusal plane inclination.

Sjögren's syndrome: a model for dental care in the 21st century.

The diagnosis and treatment of Sjögren's syndrome, which poses many severe complications, should be of critical interest to dentists, who are often the first practitioners to detect symptoms. Dentistry is an integral part of health care delivery for patients with this condition. Management of Sjögren's syndrome can be seen as a model for the expanded scope of dental care in the future.

Role of the finite element model in dental implants.

Computer-aided design and finite element methods (FEM) have interested dental researchers because of its use in the computer simulation and design of dental implants, a process greatly facilitated by the development of new computer technology and more accurate modeling technologies. FEM allows for a better understanding of stresses along the surfaces of an implant and in surrounding bone. This will aid in the optimization of implant design and placement of the implant into the bone; it will also help when designing the final prostheses to minimize stresses. The purpose of this review is to elucidate the role of FEM and the impact of this technology in clinical dentistry in the new millennium.
