Risk of tooth loss after cigarette smoking cessation. (41/186)

INTRODUCTION: Little is known about the effect of cigarette smoking cessation on risk of tooth loss. We examined how risk of tooth loss changed with longer periods of smoking abstinence in a prospective study of oral health in men. METHODS: Research subjects were 789 men who participated in the Veterans Administration Dental Longitudinal Study from 1968 to 2004. Tooth status and smoking status were determined at examinations performed every 3 years, for a maximum follow-up time of 35 years. Risk of tooth loss subsequent to smoking cessation was assessed sequentially at 1-year intervals with multivariate proportional hazards regression models. Men who never smoked cigarettes, cigars, or pipes formed the reference group. Hazard ratios were adjusted for age, education, total pack-years of cigarette exposure, frequency of brushing, and use of floss. RESULTS: The hazard ratio for tooth loss was 2.1 (95% confidence interval [CI], 1.5-3.1) among men who smoked cigarettes during all or part of follow-up. Risk of tooth loss among men who quit smoking declined as time after smoking cessation increased, from 2.0 (95% CI, 1.4-2.9) after 1 year of abstinence to 1.0 (95% CI, 0.5-2.2) after 15 years of abstinence. The risk remained significantly elevated for the first 9 years of abstinence but eventually dropped to the level of men who never smoked after 13 or more years. CONCLUSION: These results indicate that smoking cessation is beneficial for tooth retention, but long-term abstinence is required to reduce the risk to the level of people who have never smoked.  (+info)

Injury reports in a dental school: a two-year overview. (42/186)

As teaching institutions, it is vital for dental schools to collect data on accidental injuries to identify potential problems, improve the quality of care of patients, and educate future practitioners about risk management. Our data reveal important trends concerning such injuries. These data were compiled over a two-year period (2001-03) from accident reports at one dental school. We categorized the accidents as follows: source (instrument causing the injury), recipient of injury, time of day, location within the dental school where the injury occurred, and body part injured. The population examined in this study consisted of predoctoral and postdoctoral dental students, staff, faculty, and patients of the dental school. The majority of injuries occurred in the predoctoral clinic toward the middle to the end of the scheduled clinic periods. The instrument most likely involved was a needle, and the body part most commonly injured was a finger. The collection and analysis of injury data may be used to identify trends that will aid in the prediction and prevention of these injuries and, at a national level, serve as a benchmark that other dental schools can employ to assess their relative frequency of injury.  (+info)

Evolution of dental school clinics as patient care delivery centers. (43/186)

Dental school clinics, originally envisioned as closely similar to private practice, evolved instead as teaching clinics. In the former, graduate and licensed dentists perform the treatment while undergraduate dental students are assigned treatment within their capabilities. In the latter, dental students provide the treatment under faculty supervision. It is generally recognized that the care provided by the teaching clinics is inefficient. However, in the last quarter of the twentieth century, dental school clinics began to pay much more attention to how treatment is rendered. The comprehensive care movement and quality assurance systems are leading towards more efficient patient-centered care. Case studies at the University of Maryland, Columbia University, and University of Louisville describe activities to make their clinic programs more efficient and patient-friendly. This article explores whether the potential exists for faculty to take a direct patient care delivery role in dental clinics in order for those clinics to become efficient patient care delivery systems as originally envisioned in the early part of the twentieth century.  (+info)

Eye safety practices in U.S. dental school restorative clinics, 2006. (44/186)

This study was conducted to determine how much progress U.S. dental schools have made in providing eye protection during restorative (adult operative and fixed prosthodontic) procedures since a 1979 survey. A seven-question survey was placed at a website, and fifty-five different U.S. dental schools were asked to complete the survey. Thirty-one schools responded (56 percent). Eighty-four percent of schools had safety glasses available for patients, but only 77 percent required usage during restorative procedures. Similarly, while 87 percent of schools required dental students working in restorative clinics to wear safety glasses, just 73 percent enforced the policy. Additionally, 84 percent provided blue light protection on curing lights and required students to wear eye protection while doing lab procedures. Compared to the 1979 survey, considerable progress has been made over the last twenty-seven years in protecting dental school patients and students from ocular injuries. Because one would hope to have 100 percent compliance on this issue, there is room for improvement in promoting patient eye safety and teaching good habits to dental students.  (+info)

Assessment of full-time dental hygiene faculty participation in clinical practice. (45/186)

The purpose of this research project was to determine how many U.S. dental hygiene (DH) programs had full-time (FT) faculty members who provided direct patient care unrelated to the curriculum. Questions in this project also assessed attitudes and opinions of DH directors regarding clinical practice and opportunities for salary supplementation. A questionnaire of twenty open-ended and closed-ended questions was designed on Survey Monkey, an online survey engine. After IRB approval and pilot testing, 278 U.S. DH program directors received two emails with the survey link requesting their participation. A response rate of 69.1 percent (n=192) was achieved. Results revealed that 14.2 percent of the programs required FT DH faculties to participate in clinical practice settings unrelated to the curriculum, while 67 percent of the programs had faculties who also participated in clinical practice. Eighty-three percent of respondents reported faculties who participated in clinical practice were financially compensated. The majority (95.4 percent) of directors indicated maintaining clinical skills was an advantage to clinical practice, while 48 percent of directors indicated participation takes time away from being an educator. Overall, the majority of DH programs did not require FT faculties to participate in clinical practice; however, respondents were generally in favor of allowing faculties the opportunity to practice and thought that it enhanced their competency as clinical instructors.  (+info)

Caries risk assessment in an educational environment. (46/186)

This study was designed to assess, retrospectively using dental records, the impact on the management of dental caries of new caries risk assessment (CRA) forms and procedures introduced into a predoctoral dental school clinic. Of 3,659 patients with a new patient visit (NPV) and baseline exam (BE) in the two-year period of July 2003 through June 2005, 69 percent (n= 2,516) had a baseline CRA. "Visible cavitation or caries into dentin by radiograph" was significantly correlated to most items included in the CRA form, for example, "frequent between meal snack of sugars/cooked starch" (p<0.001), "inadequate saliva flow" (p=0.03), and "deep pits and fissures or developmental defects" (p<0.001). Fluoride toothpaste use (odds ratio, OR=0.7) was negatively related to cavitation risk while "readily visible heavy plaque on teeth" (OR=2.0), "frequent between meal snack of sugars/cooked starch" (OR=1.6), "interproximal enamel lesions or radiolucencies" (OR=11.8), and "white spots or occlusal discoloration" (OR=1.50) were positively related. CRA use at follow-up, the use of bacterial tests, antibacterial therapy, and specific patient recommendations were all very low. While the content and usefulness of the CRA procedures were validated, the study highlighted the difficulties of implementing such programs in educational establishments even with an extensive student didactic program and faculty training.  (+info)

The origins of fear of occupational exposure in the clinical dental setting. (47/186)

Although there is a growing literature on the incidence of occurrence and reporting of occupational exposures in clinics in dental schools, the contributing factors to fear of such injuries and their dynamic evolution over time remain unstudied. It is hypothesized that fear of occupational exposures is a function of estimated likelihood of such events and their perceived importance. Individual personality factors and situational circumstances are also thought to play a role, although it is believed that these factors recede in importance as students gain direct knowledge through clinical experience. Path analysis methods are applied to longitudinal survey data in a single dental school to confirm these hypotheses.  (+info)

Self-reported compliance with preventive measures among regularly attending pediatric patients. (48/186)

This study evaluated the compliance with preventive measures of regularly attending pediatric patients. Children attending at least four consecutive recall appointments in a pediatric dental clinic were interviewed regarding their compliance with the previously recommended preventive measures. During each recall appointment, participants and/or their parents received oral and written instructions regarding the preventive measures. Caries experience index was calculated as sum of decayed, missing, and filled surfaces of participants' primary and permanent dentition. Files of 496 children were analyzed. Mean age was 9.0 +/-4.5 years. Mean caries experience index was 7.0 +/-9.0. Participants reported eating more than six times a day (22.8 percent) and consuming in between meals water only (54.4 percent), noncarbonated beverages (23.2 percent), carbonated beverages (13.1 percent), and a combination of both beverages (9.3 percent). Children reported brushing their teeth at least once a day (94.4 percent), rinsing their teeth once a day (11.9 percent), flossing once a day (5.6 percent), and brushing once a week regularly with highly concentrated fluoride gel (12.6 percent). No statistical differences were found in compliance measures within two consecutive dental recalls. Caries experience was correlated with regular meals (p=0.01), drinks between meals (p<0.001), and toothbrushing frequency (p=0.01). In conclusion, compliance with preventive measures is low among regularly attending pediatric patients. In high caries risk patients, a frequent preventive intervention might be warranted by dental practitioners.  (+info)
