The impact of a brief tobacco-use cessation intervention in public health dental clinics.

BACKGROUND: Public health dental clinic patients use tobacco at disproportionately high rates. The purpose of this study was to evaluate a tobacco-use cessation program delivered via public health dental practitioners. METHODS: Two public health dental clinics participated in this quasiexperimental design study. First, all patients in one clinic who used tobacco (n = 178) received usual care. Next, the authors trained all practitioners to conduct a tobacco-use assessment and provide a brief cessation intervention. Subsequently, all patients in both clinics who used tobacco (N = 190) received the intervention. All enrolled patients had an income at or below the federal poverty level. The authors conducted follow-up assessments at six weeks and three and six months after enrollment. RESULTS: Differences in self-reported quitting by condition between participants in the two groups were significant across all endpoints. Patients in the intervention group were more likely to quit than those receiving usual care (15.5 versus 4.3 percent) and after 12 months (18.8 versus 4.6 percent). Controlling for enrollment differences between patients in the two groups (age, race/ethnicity, time to first cigarette after waking), the authors found that differences between groups were significant for quitting at three months (P < .05; odds ratio [OR] = 4.85; 95 percent confidence interval [CI] = 1.20, 19.60), and six months (P < . 01; OR = 5.25; 95 percent CI = 1.35, 20.36). CONCLUSIONS: The results of this study suggest the viability and effectiveness of delivering a tobacco intervention to low-income smokers via public dental practitioners. A randomized clinical trial is warranted. CLINICAL IMPLICATIONS: The potential reach of public health dental clinics is great. Because of the high percentage of tobacco-using patients in these clinics, the public health impact of a program such as the one reported here would be significant.

Stress in dental specialists: a comparison of six clinical dental specialties.

OBJECTIVE: To describe and compare the levels of stress reported by dental practitioners working within clinical dental specialties. METHOD: Questionnaire survey of 220 dental practitioners identified from the General Dental Council lists of specialist practitioners in the following clinical specialties: orthodontics, paediatric dentistry, restorative dentistry, endodontics, periodontology, prosthetic dentistry. FINDINGS: The clinical specialties did not differ in their reported levels of stress. Practitioners working in the field of paediatric dentistry reported the highest median levels of reported stress for three of the four scales, though this trend was not significant. CONCLUSIONS: The practitioners surveyed from six clinical specialties did not experience significantly different sources of stress.

Exposure to airborne methacrylates and natural rubber latex allergens in dental clinics.

The exposure of dental personnel to airborne methacrylates and natural rubber latex (NRL) allergens was studied during placing of composite resin restorations in six dental clinics in Finland. Both area and personal sampling were performed, and special attention was paid to measurement of short-term emissions from the patient's mouth. Methacrylates were collected onto thermal desorption tubes filled with Tenax TA and NRL allergens onto membrane filters. The methacrylate samples were thermally desorbed and analysed by gas chromatography with mass selective detection. The NRL allergen concentrations were determined by the allergen-specific IgE-ELISA-inhibition method. The median concentration of 2-hydroxyethylmethacrylate (2-HEMA) was 0.004 mg m-3 close to the dental nurse's work-desk and 0.003 mg m-3 in the breathing zone of the nurse with a maximum concentration of 0.033 mg m-3. Above the patient's mouth the concentration of 2-HEMA was about 0.01 mg m-3 during both working stages, i.e., during application of adhesive and composite resins and during finishing and polishing of the fillings. Maximum concentrations of 3-5 times higher than median concentrations were also measured. Triethyleneglycol dimethacrylate was released into the air mainly during the removal of old composite resin restorations (0.05 mg m-3) and only to a minor extent during finishing and polishing procedures. The median concentration of the NRL allergen was 0.12 au m-3 (au = arbitrary unit) with a maximum concentration of 1.1 au m-3. The results show that, except for short-term emissions from the patient's mouth, the exposure of dental personnel to methacrylates and NRL allergens is very low. Measures to reduce exposure are discussed, as the airborne concentrations of methacrylates should be kept as low as possible in order to reduce the risk of hypersensitivity.

Model for cost-containment planning in dental clinics.

Cost-containment possibilities in dental clinics present complex challenges to dental clinic management in the 1980s. A hypothetical model using mean cost components has been presented, together with strategies for cost reduction. Although clinical cost management is a complex task, these costs are the most significant and manageable in the dental school. Clinical cost containment is related to curriculum, faculty ego, staff morale, and many other factors separate from clinic operations. Rational cost containment requires a thorough understanding of the relative value of various costs and of the interrelation of costs, as well as firm commitment to control these costs by responsible faculty, particularly the dean. The escalating effect of uncontrolled clinical costs may result in the financial downfall of some schools in the 1980s. The observation that in the average dental school costs exceed income by a factor of approximately 3.5:1 (with an estimated range of 2:1 to 30:1) suggests that cutting costs in many schools may be more effective than raising clinic income. With inflation, the effect of the predominant cost factor versus income becomes more significant over time.

An expanded model for extramural dental clinics.

The extramural program at the University of the Pacific School of Dentistry is described. The program is designed to facilitate the students' transition from a school clinic to dental practice after graduation. Management skills are taught by providing supervised experience in a model practice setting. Five major facilities are described along with the curriculum modifications made to permit all students to spend eight four-day weeks in these remote sites. The quality control mechanism is discussed as well as four key concepts developed in the six-year experience of operating this program.

Effect of ionization on microbial air pollution in the dental clinic.

The use of spray-producing instruments in the dental clinic continuously creates a potentially harmful contamination of the room environment. In the present study a 13.5-kV corona discharge ionizing generator was used in order to investigate the effect of ions on the microbial air pollution of the dental clinic. Samples of microbial air population were collected in 9-cm-diameter plates containing either Bacto-Brain Heart Infusion Agar or Bacto-Mitis Salivarius Agar and exposed to different time periods in various locations of an active dental clinic. Microbial air levels in the dental clinic were significantly reduced with the generator (by 40-50%). The data suggest that the ionizing generator can be used to reduce the microbial air pollution within the dental clinic, thus reducing the environmental hazard of infections to the staff.

Development and evaluation of a questionnaire to evaluate clinical dental teachers (ECDT).

OBJECTIVES: To develop and test the psychometric properties (validity and reliability) of a questionnaire to evaluate clinical dental teachers. METHODS: An item (question) pool was generated with the use of a literature review, feedback from faculty staff, and from focus group discussions with dental students. Following factor analysis the validity and reliability of a revised questionnaire was assessed. This involved 148 dental students and 453 assessments of 29 clinical dental teachers. RESULTS: Effective clinical dental teaching (ECDT) scores were associated with 'global ratings' of the effectiveness of clinical dental teaching (P<0.01), indicating strong criterion validity. In comparison analysis there was strong agreement between students regarding ratings of individual clinical dental teachers, indicating good construct validity. Reliability was assessed by examining internal consistency of sub-scales and overall ECDT scale, and found to be good (Cronbach alpha's > 0.80). CONCLUSION: A valid and reliable measure to evaluate clinical dental teachers has been developed for use in a clinical academia setting, and has potential use as a quality assurance measure.

Quantitative analysis of bacterial aerosols in two different dental clinic environments.

Microbial aerosols are generated during dental treatments and may represent an important source of infection. This study was designed to quantify bacterial air contamination during dental treatments in both a closed dental operatory and a multichair dental clinic. Air was sampled by using a slit type of biological air sampler. Following air sampling, blood-supplemented Trypticase soy agar plates were incubated at 37 degrees C under anaerobic conditions for 7 days. The maximum levels of air contamination in the closed dental operatory were observed while dental treatments were being performed (four trials; 216 +/- 75 CFU/m3 for ultrasonic scaling treatments and 75 +/- 22 CFU/m3 for operative treatments). At 2 h after completion of the treatments, the bacterial counts were about the same as the pretreatment levels (12 to 14 CFU/m3). In the second part of the study, a multichair dental clinic was divided into four areas, and air contamination was monitored at each site. Three sites were located in active dental treatment areas, whereas no dental treatments were performed within an 11-m radius of the fourth site. At 3 h after the beginning of dental treatments, the highest bacterial counts were obtained in the three active dental treatment areas (76 to 114 CFU/m3). However, there was noticeable contamination in the inactive dental treatment area (42 CFU/m3). Thus, bacterial aerosols were able to spread into areas where there was no dental activity. My data show that dental treatments significantly increased the levels of bacterial air contamination in both a closed dental operatory and a multichair dental clinic.(ABSTRACT TRUNCATED AT 250 WORDS)

Multidrug-resistant Mycobacterium tuberculosis in an HIV dental clinic.

OBJECTIVE: To investigate possible transmission of multidrug-resistant tuberculosis (MDR-TB) in a dental setting. DESIGN: A retrospective, descriptive study of dental workers (DWs), patients, and practice characteristics. PATIENTS: Two dental workers (DW1 and DW2) with acquired immunodeficiency syndrome and MDR-TB. SETTING: A hospital-based (Hospital X) human immunodeficiency virus (HIV) dental clinic in New York City. METHODS: To identify dental patients with tuberculosis (TB), patients treated in the dental clinic at Hospital X during 1990 were cross-matched with those listed in the New York City Department of Health Tuberculosis Registry. Mycobacterium tuberculosis isolates from both DWs and from dental patients with TB were tested for antimicrobial susceptibility and typed by restriction fragment length polymorphism (RFLP) analysis. Infection control practices were reviewed. RESULTS: M tuberculosis isolates infecting DW1 and DW2 were resistant to isoniazid and rifampin and had identical RFLP patterns. DW1 and DW2 worked in close proximity to each other in a small HIV dental clinic in Hospital X during 1990. Of 472 patients treated in the dental clinic in 1990, 41 (8.7%) had culture-proven M tuberculosis infection. Of these 41, 5 had isolates with resistance patterns similar to both DWs; however, for four available isolates, the RFLP patterns were different from the patterns of the DWs. Sixteen of the 41 patients received dental treatment while potentially infectious. Dental patients were not routinely questioned about TB by dental staff, nor were all dental staff screened routinely for TB. No supplemental environmental measures for TB were employed in the dental clinic in 1990. CONCLUSIONS: Our investigation suggests that MDR-TB transmission may have occurred between two DWs in an HIV dental clinic. Opportunities for transmission of TB among dental staff and patients were identified. TB surveillance programs for DWs and appropriate infection control strategies, including worker education, are needed to monitor and minimize exposure to TB in dental settings providing care to patients at risk for TB.

[Hospital infections and their prevention in dental clinics].

The retrospective analysis of medical documents from several dental clinics of Kazan in 1993-1995 revealed an increase in the occurrence of different form of hospital infections (HI) in patients. As the result of our investigations, the factors of the transmission of HI among the patients of dental clinics were established, the sources of infective agents were found out and the etiology of hospital purulent inflammatory diseases in dental clinics was studied. Some measures permitting the prevention of further increase in the occurrence of HI in the patients of dental clinics are proposed.

The part-time clinical instructor in the undergraduate dental clinic.

Currently, part-time dental instructors do not receive formal training in education. According to the recent literature, some instructors may not be aware of all the options available to them in the clinic. It has been observed, for example, that instructors have demonstrated the greatest effectiveness while acting as facilitators rather than as educators. These instructors are able to incorporate their position as role models into their teaching. Dental departments must understand that the tone established in the clinic has a significant impact on the quality of their students' learning experience. This tone arises out of open dialogue between instructors and their students. The complexities of successful teaching can only be conquered when more information is provided to part-time staff.
