A clinical radiographic retrospective assessment of the success rate of single-visit root canal treatment.

AIM: To determine retrospectively the clinical and radiographic success rate of single-visit root canal treatment performed in a busy endodontic practice using contemporary techniques of canal cleaning, shaping and obturation. SUMMARY: Seven hundred and sixty-eight single-visit cases, of which 223 presented for a re-examination appointment ranging from 6 months to 4 years from the day of treatment, were considered. Four endodontists provided examinations for both root canal treatment and re-examinations. Clinical and radiographic data were used to form an overall impression of the outcomes for each case at the time of re-examination. Available demographics and treatment information of these 223 cases were compiled for comparison. The number of treatment visits was not determined by a pretreatment diagnosis or a re-assessment of the pulp status upon entry into the tooth; therefore both vital and necrotic cases, as well as those with and without periradicular pathosis, were included. Statistical analysis was carried out using Chi-square tests and considered variations in failure rates based on gender, provider, tooth type, position and arch. A t-test was used to evaluate data on age. The overall success rate was 89.2%. No statistically significant differences were seen based on gender, age, arch or provider. Statistically, anterior teeth were more successful than posterior teeth.

Dental and dental hygiene students' attitudes in a joint local anesthesia course.

In 1995, the local anesthesia course was combined for dental and dental hygiene students. It was also the first time that dental hygiene students were instructed clinically in local anesthetic techniques. Faculty felt it important to evaluate student attitudes regarding these curriculum changes. This study assessed students' perceptions of the adequacy of background preparation courses, concerns about administering local anesthetics and attitudes about its administration by dental hygienists. A pre/post survey was completed by dental and dental hygiene students. T-tests were used to determine if differences in attitudes existed between groups and if changes in attitudes occurred within groups after taking the course. Results indicated that both groups believed they had adequate background preparation. Apprehensions about administering local anesthetics were similar, but the dental hygiene students felt significantly less anxiety (p < 0.01). Results also differed significantly on the issue of hygienists administering local anesthetics, with hygiene students in support of it and dental students opposed (p < 0.01). Results confirmed that no changes were needed in the existing prerequisite courses for both groups. A need to address student anxiety about local anesthetic administration has been identified. In addition, it may be beneficial to expand dental students' appreciation of dental hygiene education to foster mutually successful working relationships in the future.

Gender and the transition into practice.

Since 1990, over half the enrollees in advanced education pediatric dentistry programs have been women. The higher proportion of women in pediatric dentistry should permit examination of the practice patterns of groups of men and women at similar stages in their careers. In 1991 the American Academy of Pediatric Dentistry surveyed 4,950 dentists about a variety of issues related to practice patterns and demographics, obtaining 2,362 responses. This study conducted a secondary analysis of the survey data by developing three age-matched graduation cohorts based on gender and years since graduation: 1 to 5 years, 6 to 10 years, and over 10 years. Four areas were investigated: practice patterns, practice arrangements, distribution of time, and income. The overall differences in practice patterns between males and females were statistically significant for the Early Career Group (1 to 5 years). More males were in private practice and a higher proportion of them were practice owners. More women were dental school faculty or in private practice as an employee or contractor. The differences in practice patterns for males and females were not statistically significant for the Intermediate Career Group (6 to 10 years). In the Established Career group (over 10 years), the differences were again statistically significant, with more males as practice owners and shareholders and more women in solo practices. Analysis of time distribution showed that, in the two earlier career groups, women spend about twice as much time as men in child care. These findings may help to explain why many women in the early stages of their careers might prefer the flexibility of working for someone else. When the effects of gender and employment status on income were tested, significant differences were found for the Intermediate and Established groups, with males and practice owners having higher income levels.(ABSTRACT TRUNCATED AT 250 WORDS)

Survey of clinic fees and clinic revenue--summary report, 1993-94.

Figure 4 shows the mean unadjusted revenue-per-student by program type. Advanced Education General Dentistry programs had the highest revenue-per-student this year and in two of the three previous years. Oral and Maxillofacial Surgery programs generated the second highest mean amount of clinic revenue-per-student, followed by General Practice Residencies, Orthodontic programs, and Prosthodontic programs. Pediatric Dentistry, Endodontics, and Periodontics programs also had similar mean revenues-per-student. The smallest revenues-per-student were generated by D.D.S./D.M.D. and dental hygiene programs. These data should be interpreted with care. A review of the information for each program shows that there are significant variations in these data from school to school. These variations could be caused by different accounting procedures as well as differences in program size and location. Consequently, these data are best viewed in general terms.

The primary dental care workforce.

With health care reform at the forefront of our nation's policy agenda, an assessment of the current status of the dental primary care workforce is required as an essential reform component. There has been much written in the literature about manpower but relatively little about the primary dental care workforce. The purpose of this paper is three-fold: 1) to describe the current primary dental care workforce; 2) to identify the distribution of this workforce; and 3) to describe the current delivery system. Characteristics, distribution, and delivery systems of the primary dental care workforce in the private and public sectors are described, and workforce issues relevant to health care reform are identified for future discussion.

Issues in the dental care management of patients with bloodborne infectious diseases: an opinion survey of dental school seniors.

This study revealed some significant findings concerning the views of dental school seniors. Through a series of questions, we determined the opinions that seniors had about treating patients with bloodborne infections and the way they regarded their professional responsibility to provide care to these patients. We were able to identify that the majority of seniors had knowingly treated patients with one of these diseases, and believed that they had a professional obligation to do so. The study showed that these future professionals were aware of the risks related to disease transmission and they had real concerns about those risks; nevertheless, they were prepared to accept their professional obligation to provide care to these individuals. More than half of the survey population was fearful of treating patients with these diseases, and over half indicated that they would not treat these patients given the choice. This fear was compounded by their presumption that other patients would not want to be treated by a dentist who provides care to HBV/HIV patients, and by the presumption of increased cost of infection control. More than three fourths of these dental seniors agreed that treatment of infected patients would place them at higher risk. Nevertheless, in the face of this perceived danger, 62 percent indicated that they were willing to treat these patients, 79 percent said that they were capable of treating them, and 76 percent acknowledged the responsibility of the profession to treat. Another finding of note involves the treatment of infected patients and the effect that treatment experience had on the seniors' attitudes.(ABSTRACT TRUNCATED AT 250 WORDS)
