The use of clinical dental auxiliaries as examiners in caries prevalence surveys in the United Kingdom: a feasibility study.

OBJECTIVE: This study investigated the use of clinical dental auxiliaries as examiners in caries prevalence surveys of 5- and 12-year-old children in the United Kingdom. METHODS: A random sample of four therapists and four hygienists was drawn from 23 clinical dental auxiliaries employed in the Community Dental Service in Yorkshire, United Kingdom. Training and calibration were carried out according to national guidelines for caries prevalence surveys. Sixteen 5-year-old and sixteen 12-year-old children were examined in the calibration exercise. Agreement was assessed using 95% confidence intervals of mean dmft/DMFT of the group, sensitivity and specificity values, and kappa statistics on dft/DFT. RESULTS: For 5-year-old children, a good level of agreement with the standard examiner was achieved with sensitivity scores ranging from 0.84-0.98, specificity scores from 0.93-0.97, and kappa scores from 0.80-0.89. For 12-year-old children, sensitivity scores ranged from 0.56-0.95; specificity scores from 0.93-0.99; and kappa scores from 0.66-0.83. Four examiners failed to achieve the minimum scores on all measurements. CONCLUSION: It was concluded that clinical dental auxiliaries could be used as examiners in caries prevalence surveys of 5-year-old children. However, in order to attempt to meet the national standard for agreement in surveys of 12-year-old children, four of the eight examiners in the present study would require further training. Possible reasons for this difference are discussed.

The mercury burden in waste water released from dental clinics.

The aim of this study was to estimate mercury burden in waste water samples collected during one working day in 27 dental clinics. The samples were subjected to authorized analysis using the technique of QS-IE Enhanced Cold Vapour Mercury Analyzer to estimate the amount of mercury discharged. The mean value of mercury discharged was 2.49 parts per billion (ppb) for the clinics equipped with amalgam separators and 94.75 ppb for the clinics without amalgam separators. Some of the small amalgam particles released when new fillings are placed or during removal of old restorations form a sediment in tubes and drains. The remaining particles are carried with the waste water stream to the local purifying plant. If threshold values for heavy metal content including mercury are exceeded, the sludge is not allowed to be recycled as fertiliser. Installation of an approved amalgam-separating apparatus in dental clinics is recommended so as to reduce considerably the discharge of mercury into waste water.

Dental materials in Papua New Guinea: a survey of dental clinics.

Questionnaires were distributed to 55 Public Health and Defence Force dental clinics throughout Papua New Guinea in order to ascertain storage and clinical conditions, as well as information related to the type, consumption and performance of alginate and elastomeric impression materials and composite restorative materials. Of the 39 respondents, representing a 71% return, few reported any problems with either of the two types of impression materials. However, complaints associated with the use of paste-paste composites, Adaptic and Concise, were a major concern. It was assumed that the problems were caused by exposure to excessively high temperatures during shipment, distribution and storage of these materials throughout Papua New Guinea. Alternative materials, which are less sensitive to heat, were proposed for use in Papua New Guinea. These were a light-activated composite (Durafill), a powder-liquid composite (Powderlite) and a powder-water glass ionomer (Chemfil II).

[The results of caries prophylaxis after 25 years of the School Dental Clinic in the city of St. Gallen].

Since 1966 the School Dental Clinic of St. Gall has been in charge of preventive dentistry and treatment of school and kindergarten children. For children from kindergarten and the 1st level of primary school, the caries incidence rate was established in percentages. For those of 14 years of age, the DFM-T index (including 2 bit-wings) was determined. For the 14-year-old children the average number of carious, filled and extracted teeth (DMF-teeth) decreased as follows: 1974 DFM-T = 7.0; 1978 DMF-T = 5.0; 1982 DMF-T = 3.0; 1987 DMF-T = 2.7; 1991 DMF-T = 1.1. The percentage of children with a healthy natural dentition in this age group was approximately 40% in 1991. The number of extractions of permanent teeth dropped 15 times, the number of required tooth fillings up to 5 times. Whilst children of 14 years of age in 1991 showed a minimum of carious lesions, the caries prevalence of kindergarten children and those of 1st level primary school increased slightly (partly due to influx of foreigners). This fact draws attention to the significance of a uniform, continuous and systematic prevention in the future.

A custom-designed computer network for a dental clinical school.

A local area computer network has been designed and implemented to service predominantly the patient-related administrative needs of the Westmead Dental Clinical School. The appropriate software has been developed in-house over a period of time and introduced as the complexity and volume of the tasks increased and as more sophisticated hardware became available. The present arrangement utilizes NEC APC III and NEC APC IV computers with ACSinet networking hardware added to an OMNInet system. Primary functions include the management of extensive patient waiting lists (up to 16,000), treatment lists and laboratory work flow, as well as the provision of a wide range of related statistical information. Wordprocessing is a large scale daily activity. More specialized secondary functions include monitoring of patients allocated to dental students, support of the management of appointments, recalls, mailing lists and some specific research projects including data collection for a quality assurance programme. The network functions separately but simultaneously alongside an extensive hospital-wide VAX cluster and has greatly simplified the handling and management of a vast array of data essential to the management and evaluation of the treatment provided in the Dental Clinical School.

Microbial contamination of "in use" bar soap in dental clinics.

Bar soap from 18 different dental clinics were investigated for microbial contamination, while it was "in-use". Of the 32 samples obtained from the bar soap, 100% yielded positive culture. A total of 8 different genera of organisms were isolated. Each bar soap was found to harbor 2-5 different genera of micro organisms. Heavily used soap had more micro organisms compared to less used soap. The microbial load of the "in-use" bar soap constituted a mixed flora of gram positive, gram negative, aerobes, anaerobes, and fungi. The results indicate that the bar soap under "in-use" condition is a reservoir of microorganisms and handwashing with such a soap may lead to spread of infection.

Patient receptivity to tobacco cessation counseling in an academic dental clinic: a patient survey.

OBJECTIVE: This study investigated dental patient attitudes towards tobacco cessation counseling in the dental school setting. METHODS: Patients attending an academic dental clinic during a six-week period were asked to complete a 22-item self-administered survey. Means and frequency distributions were assessed on all variables as appropriate. RESULTS: Response rate was 71%. Twenty-nine percent of respondents reported that they currently used tobacco. Seventy-two percent of tobacco users agreed that the student dentist should ask patients whether or not they use tobacco, 67% agreed that the student dentist should advise tobacco users to quit, and 89% agreed that student dentists should offer quit tobacco information to patients who want to quit. Seventy percent of tobacco users were considering quitting or currently trying to quit. Of these, only 31% were aware of community resources to help them quit. CONCLUSIONS: The majority of tobacco users were positive in their attitudes toward delivery of tobacco cessation counseling and services in the dental setting. Many were considering or trying to quit, but few were aware of community resources to help them.

[A case of malignant hyperthermia occuring in a dental clinic].

Malignant hyperthermia, a life-threatening complication of anaesthesia, occurred in a 5 1/2-year-old girl undergoing dental surgery in a dental clinic. During induction, after 20 mg of succinylcholine, the anaesthetist noted a moderate rigidity of the mandible that did not interfere with the tracheal intubation. However, after 45 minutes, the temperature rose to 38.8 degrees C, pulse was rapid at 160 per minute and the child was slightly cyanosed. The diagnosis of malignant hyperthermia was made (the temperature eventually reached 40.8 degrees C). The child was immediately treated with refrigeration, procainamide and sodium bicarbonate. She was then moved to a hospital centre where the treatment was continued and she recovered completely. After extensive investigation, we found that the paternal grandfather of the child died at age 58, several hours after a bilateral lumbar sympathectomy under general anaesthesia. The cause of the death, as confirmed by hospital records, was malignant hyperthermia. No genetic counselling was given at that time; this omission has since been corrected. Early diagnosis and the availability on the premises of the necessary drugs and equipment to treat such a complication probably saved this child's life. In 1975, "La Corporation Professionnelle des Médecins du Québec" published standards for practice of anaesthesia outside a hospital setting. The compliance of the dental clinic with such standards has contributed to the avoidance of a catastrophe.

Trends in treatment performed in the Phelophepa Dental Clinic: 1995-2000.

Mobile clinics are a cost-effective method of meeting the dental needs of rural communities in South Africa. Phelophepa, the first primary health care train of its kind world-wide, provides eye care, education, medicine, basic health care and since June 1995 dental treatment to rural communities. All services are rendered by students under supervision of qualified staff. The aim of this study was to analyse and report the data for treatment performed in the dental clinic from June 1995 to May 2000. During its first five years of operation, dental services were provided at 183 towns in all provinces except Gauteng. Of the 42,073 patients treated during this time (an average of 229.9 per town), 67.4% were adults. 71.3% of the 103,283 procedures performed were extractions, 15.7% could be classified as preventive with the remaining 13% as restorative procedures. The average value of the service provided to each patient was R218.53. The exposure of dental, dental therapy and oral hygiene students to rural areas of South Africa serves the important purpose of sensitising students to the realities of oral diseases in these communities.

Dental clinical teaching: perceptions of students and teachers.

The objective of this study was to explore perceptions of dental student clinicians and clinical teachers about dental clinical teaching to provide primary data for dental researchers and educators. Student focus group data provided background for development of a questionnaire that explored three themes related to clinical teaching. Twenty-one teachers and forty-five student respondents completed the twenty-five-item questionnaire in 2003. In the theme of the teacher/student relationship, no statistically significant differences were seen between teacher and student group perceptions. In the theme of educational theory applied in dental clinical teaching, a statistically significant difference was seen between teacher and student groups in the value of preclinical instruction in senior clinical years and in the value of a clinical log book. In the theme of skills required for clinical dental practice, a statistically significant difference was seen between teacher and student groups in the value of a critical appreciation of evidence-based practice as one of the skills. The study overall indicates that the dental clinical learning environment supports close perceptual conformity between students and clinical teachers in regard to what each group considers to be "good practice" in clinical teaching. The findings of this study indicate that some techniques that have been advocated to enhance clinical learning, such as evidence-based teaching methods, require further investigation.

Analysis of attendance rates at Soweto dental clinics 1995-2002.

BACKGROUND: Patient attendance rates at Soweto dental clinics increased during the year after the implementation of free primary oral health care in 1995. OBJECTIVE: This study was performed to examine if the attendance rates continued to increase between April 1995 and March 2002. MATERIALS AND METHODS: Monthly clinic records were used to record casual (pain and sepsis treatment) and booked patient attendance (restorative, prosthetic and orthodontic treatment) and number of dental operators in the nine primary health care clinics and one hospital clinic in Soweto. Data were analysed with SAS and Prism software. RESULTS: Total patient attendances in the primary health care clinics significantly increased from 6,161 in 1995 to 10,519 in 2002 (P<0.05) due to an increase in casual patients Booked patients decreased and patients treated per operator increased. In the hospital clinic the casual patient attendances decreased but booked patients significantly increased (P<0.005). CONCLUSIONS: Patient attendance rates increased between 1995 and 2002 with an increase in dental operator workload.

Zygomatic air cell defect (ZACD). Prevalence and characteristics in a dental clinic outpatient population.

OBJECTIVES: To determine the prevalence and characteristics of zygomatic air cell defect (ZACD) among a general dental clinic population. METHODS: The panoramic radiographs of 2734 dental clinic outpatients were examined for the presence of ZACD. ZACD was defined as a nonexpansile, nondestructive cyst-like radiolucency in the zygomatic process of the temporal bone which appears similar to the mastoid air cells and which does not extend further anteriorly than the zygomaticotemporal suture. RESULTS: ZACD was found in 40 patients (1.5%) with a mean age of 49.6 (s.d. 18.0) years. Twenty cases (50%) each occurred in males and females. Meta-analysis of three large case series comprising 4579 patients revealed a total of 76 cases of ZACD (1.7% prevalence) occurring over an age range of 15-83 years. Thirty-four (44.7%) occurred in males while 42 (55.3%) occurred in females. Bilateral ZACD were found in 17 patients (22.4%). CONCLUSIONS: ZACD is not a rare anatomical variant, and clinicians planning eminectomy or other surgical procedures involving the zygomatic arch are advised to obtain appropriate presurgical imaging studies to avoid the need for creative intra-operative reconstruction.

Delivery of comprehensive children's dental services using portable dental clinics in NYC public schools. A six-year analysis.

In 1990, the Bureau of Dental Health Services of the New York City Department of Health launched a major initiative to modernize a network of school-based dental clinics located throughout the city. Since 1913, the bureau has provided dental care to public school children; however, the clinics were not properly maintained or upgraded, and were in a state of disrepair and obsolescence. Anticipating that the survival of the program was in question, the school program was converted to a fleet of state-of-the-art portable dental clinics permitting targeting of underserved, high-risk poor and immigrant populations. Demographics had changed dramatically over the years; the program could now situate services where they were needed most, and provide a broader array of care where access was a problem. This paper presents a six-year analysis of the program and builds a strong case to show that a portable delivery system can equal or in many ways surpass the effectiveness and capabilities of a fixed-state approach.

The effect of confirmation calls on appointment-keeping behavior of patients in a children's hospital dental clinic.

PURPOSE: The objective of this prospective, randomized, controlled study was to evaluate whether confirmation calls made one or two working days before scheduled appointments reduce the percentage of broken appointments in a children's hospital dental clinic. METHODS: Patients were randomly assigned to three groups: 1) confirmation call made one working day before appointment, 2) confirmation call made two working days before appointment; and 3) control group (no confirmation call). Clinic staff made confirmation calls during normal office hours. Patient arrival was classified as 1) < or =15 minutes late; 2) > 15 minutes late; or 3) broken appointment. RESULTS: Three hundred and thirteen subjects were enrolled in the study: 77 subjects in group 1; 71 subjects in group 2; and 84 subjects in the control group. Eighty-one subjects (26%) could not be contacted by telephone. Overall, there was a 62% reduction in broken appointments among patients who received a confirmation call as compared to the control group. There was no significant difference between confirmation calls placed one or two working days prior to the appointment (P=0.51). Confirmation calls had no effect on punctuality. In comparing indigent care and private insurance, there was no significant difference in broken appointments. However, within the private insurance group, a confirmation call resulted in 93% of patients keeping their appointment as compared to 63% in the control group (P<0.001). No significant difference was noted in the indigent care group, with 79% of patients in the confirmation call group keeping their appointments as compared to 66% in the control group (P=. 093). CONCLUSIONS: Confirmation calls reduced the percentage of broken appointments in a pediatric dental clinic. There was no difference between calls placed one or two working days prior to the appointment. The greatest reduction in broken appointments was shown in the private insurance group.

British Isles symposium on the future of dental clinical skills training.

A symposium on the future of dental clinical skills training is reported. Abstracts of the symposium presentations review the current and future use of simulation in dental education, future skills training in the creation of new dentists, equipment and methods for simulation, the transition from simulation to clinical practice and recent developments in simulation employing new technologies. The report concludes that simulation will continue to have an important, probably increasing role in dental education, and that further developments in clinical skills training should be sensitive to changing patterns of dental disease and opportunities of provide clinical instruction.
