Patients with special health care needs in general and pediatric dental practices in Ontario.
(33/103)
The objective of this study was to determine the involvement of Ontario's general and pediatric dentists in providing care to patients with special health care needs (PSHCNs). A questionnaire was developed and sent to a randomly selected sample of general dentists and to all pediatric dentists in Ontario; response rates were 52% and 90%, respectively. Most general dentists and all pediatric dentists reported that they provided a full range of dental services to PSHCNs. Most (80%) general dentists treat PSHCNs of all ages, whereas 60% of pediatric dentists report only treating PSHCNs up to the age of 18 years. A majority of both groups report treating PSHCNs whose dental care is paid through various government-funded programs. Most general dentists received training in the treatment of PSHCNs in undergraduate dental school, and 40% reported taking continuing education courses in this area. Most pediatric dentists received this training during their advanced dental specialty training, and 29% reported taking continuing education courses in this area. The results of this survey appear to demonstrate that general and pediatric dentists in Ontario provide a full range of dental services to PSHCNs, treat patients with a variety of disabilities and of all ages and are interested in pursuing continuing education that focuses on the delivery of dental care to PSHCNs. However, the results may be inaccurate because of question design flaws and responder bias among the 52% of surveyed general dentists who returned their questionnaires. (+info)
Antimicrobial analysis of different root canal filling pastes used in pediatric dentistry by two experimental methods.
(34/103)
The objective of this study was to compare, by two experimental methods, the antimicrobial efficacy of different root canal filling pastes used in pediatric dentistry. The tested materials were: Guedes-Pinto paste (GPP), zinc oxide-eugenol paste (OZEP), calcium hydroxide paste (CHP), chloramphenicol + tetracycline + zinc oxide and eugenol paste (CTZP) and Vitapex. Fiven microbial strains (S. aureus, E. faecalis, P. aeruginosa, B. subtilis and C. albicans) obtained from the American Type Culture Collection were inoculated in Brain Heart Infusion (BHI) and incubated at 37 degrees C for 24 h. For the direct exposure test (DET), 72 paper points were contaminated with the standard microbial suspensions and exposed to the root canal filling pastes for 1, 24, 48 and 72 h. The points were immersed in Letheen Broth (LB), followed by incubation at 37 degrees C for 48 h. An inoculum of 0.1 mL obtained from LB was then transferred to 7 mL of BHI, under identical incubations conditions and the microbial growth was evaluated. The pastes showed activity between 1 and 24 h, depending on the material. For the agar diffusion test (ADT), 30 Petri plates with 20 mL of BHI agar were inoculated with 0.1 mL of the microbial suspension, using sterile swabs that were spread on the medium. Three cavities were made in each agar plate (total = 90) and completely filled with one of the filling root canal pastes. The plates were pre-incubated for 1 h at room temperature and then incubated at 37 degrees C for 24 to 48 h. The inhibition zone around each well was recorded in mm. The complete antimicrobial effect in the direct exposure test was observed after 24 h on all microbial indicators. All root canal filling materials induced the formation of inhibition zones, except for Vitapex (range, 6.0-39.0 mm). (+info)
Self-reported compliance with preventive measures among regularly attending pediatric patients.
(35/103)
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)
Urgent care in the dental school setting: analysis of current environment and future challenges in emergency dental education.
(36/103)
Urgent dental care education is a critical aspect of the D.D.S. curriculum as dental students must be adequately prepared to face real-world dental emergency challenges in practice. Dental emergency education is likely the most variable component of the dental curriculum. To assess potential differences in emergency education, a sixteen-question survey was sent to directors of urgent care of all fifty-six U.S. dental schools addressing clinic operation, demographics, treatment, integration into the D.D.S. curriculum, and provision of care for indigent populations. The response rate was 88 percent. Results indicate a need for earlier integration of urgent dental care education into the D.D.S. curriculum, more pediatric emergency experiences for D.D.S. students, and a more rigorous academic approach in assessing student competency while on rotation in the urgent care service. In addition, access to emergency dental care has become increasingly difficult for indigent populations due to lack of state-supported funds; further exploration of sources of external funding for such care is warranted.

Intra- and inter-examiner variability in evaluating preclinical pediatric dentistry operative procedures.
(37/103)
Many investigators have reported attempts to develop reliable laboratory and clinic evaluation systems. However, few studies, regardless of level of success, have used an analytic procedure to identify those components of the evaluation system that, if refined further, could improve reliability. The purpose of this study was to compare intra- and inter-examiner variability in two evaluation methods: glance and grade (global), and checklist and criteria (analytical). Three faculty staff members with more than ten years of clinical and teaching experience evaluated operative procedures performed on plastic teeth representing the primary teeth by thirty dental students in pediatric dentistry preclinical laboratory sessions. The preparations were graded blindly by each of the three evaluators (A, B, and C) three times without magnification. The values were statistically analyzed using Wilcoxon signed rank test and Friedman test setting value of significance at 5 percent. The study revealed that, among the three examiners, the intra-examiner variability was nonsignificant in most situations. On the other hand, there was statistically significant variability between evaluators (i.e., inter-examiner) for almost all preparations. Neither cutting off the scores nor using either evaluation method (glance and grade or criteria and checklist) caused an improvement in variability. The problem of inter-examiner reliability and variability still existed. (+info)
Portable digital video instruction in predoctoral education of child behavior management.
(38/103)
The goals of this exploratory study were to determine students' assessment of portable digital video instruction (using the Apple iPod) and to compare examination performance among groups of predoctoral dental students who did and did not utilize portable digital video instruction as a supplement to a conventional pediatric behavior management lecture. Dental students received a one-hour lecture on communication with the parent and child patient as part of their regular sophomore pediatric dentistry curriculum. Digital audio and digital video versions of this lecture were made available to all 113 students in the class. Eleven student volunteers were loaned portable digital video players (the iPod) containing the lecture for a two-week period. Upon completion of the study period, the entire class participated in an anonymous fifteen-minute post-intervention written assessment including a thirteen-item examination covering lecture material. Students who had used the iPod to review the digital video lecture material favored this medium as a pedagogical instrument and as a group performed significantly better on the examination than those who had not reviewed the digital material (p=0.034). In conclusion, portable digital instructional videos may be a useful educational methodology to help predoctoral dental students acquire knowledge in pediatric behavior management. (+info)
Illinois dental anesthesia and sedation survey for 2006.
(39/103)
This is a 10-year follow-up survey of a 1996 study of all dentists in Illinois holding a permit to administer sedation or general anesthesia. The survey describes the scope of sedation and anesthesia services provided in dental offices in Illinois. A mail survey was sent to 471 dentists who were registered with the department of professional regulation to administer sedation or general anesthesia. Classification by specialty area of practice showed: 63% (84% in 1996) are oral and maxillofacial surgeons, 20% (11% in 1996) general dentists, 6% (5% in 1996) periodontists, 9% (0% in 1996) pediatric dentists, 1% (less than 1% in 1996) dentist anesthesiologists. Advanced cardiovascular life support (ACLS) training was reported by 90% (85% in 1996) of the respondents. The total number of sedations and general anesthetics administered for the year was 115,940. Two mortalities and two cases of long-term morbidity were reported for the 10-year period. Respondents reported that 30 patients required transfer to a hospital but suffered no long-term morbidity. Other practice characteristics were detailed. (+info)
Teaching alternatives to the standard inferior alveolar nerve block in dental education: outcomes in clinical practice.
(40/103)
Surveys were sent to Harvard School of Dental Medicine students and graduates from the classes of 2000 through 2006 to determine their current primary means of achieving mandibular anesthesia. Orthodontists and orthodontic residents were excluded. All subjects received clinical training in the conventional inferior alveolar nerve block and two alternative techniques (the Akinosi mandibular block and the Gow-Gates mandibular block) during their predoctoral dental education. This study tests the hypothesis that students and graduates who received training in the conventional inferior alveolar nerve block, the Akinosi mandibular block, and the Gow-Gates mandibular block will report more frequent current utilization of alternatives to the conventional inferior alveolar nerve block than clinicians trained in the conventional technique only. At the 95 percent confidence level, we estimated that between 3.7 percent and 16.1 percent (mean=8.5 percent) of clinicians trained in using the Gow-Gates technique use this injection technique primarily, and between 35.4 percent and 56.3 percent (mean=47.5 percent) of those trained in the Gow-Gates method never use this technique. At the same confidence level, between 0.0 percent and 3.8 percent (mean=0.0 percent) of clinicians trained in using the Akinosi technique use this injection clinical technique primarily, and between 62.2 percent and 81.1 percent (mean=72.3 percent) of those trained in the Akinosi method never use this technique. No control group that was completely untrained in the Gow-Gates or Akinosi techniques was available for comparison. However, we presume that zero percent of clinicians who have not been trained in a given technique will use the technique in clinical practice. The confidence interval for the Gow-Gates method excludes this value, while the confidence interval for the Akinosi technique includes zero percent. We conclude that, in the study population, formal clinical training in the Gow-Gates and Akinosi injection techniques lead to a small but significant increase in current primary utilization of the Gow-Gates technique. No significant increase in current primary utilization of the Akinosi technique was found. (+info)
