ItemCultural competence skills in a dental curriculum: A review(WILEY, 2018-02)UNLABELLED: This study aimed to analyse and evaluate the extent of transcultural content in the current curricula of the Doctor of Dental Surgery (DDS), Bachelor of Oral Health (BOH) and Master of Nursing Science (MNSc) courses at the University of Melbourne. METHODS: The study was conducted in two phases: a quantitative review and assessment of the current DDS, BOH and MNSc curricula at the University of Melbourne, and interviews with various staff from the University of Melbourne who were responsible for curriculum development for these courses. RESULTS: Staff from the DDS, BOH and MNSc courses concurred on the importance of transcultural skills, the necessity of covering cultural issues relevant to the main ethnic groups in Australia, obstacles faced and the lack of evaluation methods for cultural competency. The nursing curriculum had the most extensive coverage of transcultural content throughout both years of the course (total 71 formal contact hours; mean 36 formal contact hours per year). In contrast, modules on transcultural skills were limited to the first two of the 3-year BOH course (54 hours; 18 hours) and only the first of the 4-year dental curriculum (40 hours; 10 hours). CONCLUSION: The DDS course showed less time devoted to formal teaching of these concepts compared to the nursing and BOH courses despite showing a noticeable improvement from a previous assessment conducted in 2006. It is hoped that the DDS course continues to further increase the transcultural content and find ways to incorporate more transcultural education.

ItemCultural competency and communication skills of dental students: clinical supervisors' perceptions(WILEY, 2017-11)OBJECTIVES: This study explored clinical supervisor's (CS) views and experiences of dental students' cultural competence (CC) at the Melbourne Dental School, The University of Melbourne, Australia. Additionally, this study explored CS insights into how CC could be taught. METHODS: Semi-structured one-to-one interviews were organised with consenting CS. Interview topics included the following: the importance of CC, communication and rapport, the role of culture in oral health and the need for curriculum enhancement. Interviews were recorded, transcribed and thematically analysed to identify key areas using NVivo software. RESULTS: A total of 12 CS participated in this study. CS acknowledged the importance of CC and felt that it was important for good patient management. CS's definition of CC focused primarily on language and communication skills. CS felt that dental students were generally able to manage culturally diverse patients. However, CS indicated that additional training in this area would be beneficial. Concerns were raised about the students' ability to establish good rapport and communication, with CS highlighting areas such as misuse of interpreters and use of jargon. CS felt that clinical experience, confidence and a positive attitude are effective tools for overcoming cultural barriers. Furthermore, some CS also felt that cultural competency was a skill that is learnt through experience. CONCLUSIONS: For most CS, cultural competence was an important part of the clinician-patient exchange which would benefit from enhanced curriculum. They also highlighted areas where transcultural education could be improved. The majority of CS believed dental students managed culturally diverse patients well.

ItemPsychological and behavioral acculturation in a social network of Mexican Americans in the United States and use of dental services(WILEY, 2016-12)OBJECTIVES: We used data from the TalaSurvey study to examine associations between dental health experiences, social network characteristics, and levels of behavioral and psychological acculturation in one location in the American Midwest. METHODS: Starting in parishes and community organizations, we identified adults of Mexican origin living in Indianapolis, who were 1st- or 2nd-generation immigrants from Tala, Mexico. Using a social networks methodology and following extensive formative research, we created an egocentric social network survey and administered it via face-to-face interviews. We identified the peers (alters) in interviewees' (egos) personal networks. We asked egos about multiple oral health and dental care variables for self and for alters. Acculturation (psychological and behavioral) was measured with a validated tool. Through logistic and negative binomial regression, we examined the effects of acculturation and network composition on ego's dental insurance status, dental office visits, and the reason for most recent dental office visit. RESULTS: A total of 332 egos (mean age 36; 63% female) were interviewed: 90% were born in Mexico; 45% had completed elementary school or lower; and most had low income. Each ego named 3.9 (SD±1.9) alters in his/her personal network, for a total of 1299 alters (mean age 39; 61% female). Both behavioral acculturation and psychological acculturation were moderately associated with dental insurance coverage, and greater behavioral acculturation predicted more frequent dental care. More psychologically acculturated egos were more likely to seek preventive care. Further, egos with more highly educated networks sought care more frequently and for preventive purposes, net of ego's own education and acculturation. CONCLUSIONS: This study contextualizes acculturation of Mexican Americans within the personal networks in which oral health discussion takes place. The findings underscore the critical importance of acculturation and social network factors in shaping a subgroup of Latinos' orientation toward dental care.

ItemCarious lesion severity and demarcated hypomineralized lesions of tooth enamel in schoolchildren from Melbourne, Australia(WILEY, 2018-09)BACKGROUND: Developmental hypomineralized lesions of enamel (DHL) may represent a significant caries-risk factor. The aim of this study was to determine the association between carious lesion severity and DHL in 6- to 12-year-old schoolchildren from Melbourne, Australia. METHODS: The sample was derived from randomly selected schools in inner Melbourne. A full dental examination was performed at the school. Socio-demographic data, caries experience (DMFT/dmft/ICDAS II) and the consequences of untreated carious lesions (PUFA/pufa) were measured. DHL, molar incisor hypomineralization (MIH) and hypomineralized second primary molar (HSPM) presence were assessed using the European Academy of Paediatric Dentistry (EAPD) criteria. RESULTS: Of the children examined (n = 327), 26.9% had DHL. The prevalence of MIH and HSPM was 14.7% and 8%, respectively. Almost 20% of children had severe carious lesions (ICDAS 5 & 6) in at least one permanent or primary tooth. Ordinal regression analyses indicated that DHL (OR = 2.17; 95% CI: 1.35-3.49) and being born overseas (OR = 2.59, 95% CI: 1.66-4.06) increased the likelihood of severe carious lesions. CONCLUSIONS: One of four children had DHL. DHL-affected children had an increased likelihood of presenting untreated severe carious lesions compared with DHL-free children.

ItemAntibiotic resistance and relevance to general dental practice in Australia(WILEY, 2018-12)Antibiotic resistance is a well-established global public health crisis, with the use and misuse of antibiotics being the principal cause of bacterial resistance. Studies in both Australia and overseas have demonstrated that the dental prescribing of antibiotics is increasing and that dentists tend to prescribe antibiotics unnecessarily and for incorrect clinical indications. Dental practitioners in Australia also prefer to prescribe moderate to broad-spectrum antibacterial agents and make some inappropriate antibiotic prescribing choices. This review aims to inform dentists about the overall scope and development of bacterial resistance, approaches and challenges to reducing resistance and, ultimately, the role of dental prescribers in practising with optimal antibiotic stewardship.

ItemCurrent prescribing trends of antibiotics by dentists in Australia from 2013 to 2016. Part 1.(WILEY, 2018-09)BACKGROUND: Literature has shown dentists tend to overprescribe antibiotics and do not always prescribe in accordance with recommended guidelines. Unnecessary prescribing is one major factor that contributes to the development of antibiotic resistance. The aim of the present study was to assess the antibacterial prescribing patterns of dentists in Australia from 2013 to 2016. METHODS: Data on dental antibacterial prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 was accessed and prescribing trends analysed. The prescribing rates were standardized to the dose and population. RESULTS: There was a slight decrease in the dispensed use of most antibacterials from 2013 to 2016, but there was a significant increase in the dispensed use of amoxicillin/clavulanic acid of 11.2%. Amoxicillin was the most commonly dispensed antibiotic, accounting for approximately 65% of all antibacterials from 2013 to 2016, while phenoxymethylpenicillin accounted for only 1.4% of prescriptions in 2016. There were low but significant quantities of dispensed antibiotic prescriptions that do not fit with current guidelines. CONCLUSIONS: The data suggest that dentists in Australia are prescribing some antibiotics inappropriately and there is a preference for moderate- to broad-spectrum agents. The current PBS dental schedule is inconsistent with prescribing guidelines and may contribute to inappropriate prescribing.

ItemCurrent prescribing trends of dental non-antibacterial medicines in Australia from 2013 to 2016. Part 2.(WILEY, 2018-09)BACKGROUND: There is limited literature regarding dental prescribing preferences for medicines other than antibiotics. This study aimed to describe the prescribing trends of dispensed prescription medicines by dentists in Australia from 2013 and 2016 and assess adherence to current guidelines. METHODS: Data were accessed from the Department of Health of all dental prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 and prescribing patterns were analysed. The prescribing rates were standardized to the dose and population. RESULTS: There was an overall increase in the standardized use of opioid analgesics by almost 30% over the time frame, with the combination paracetamol 500 mg plus codeine 30 mg tablet accounting for the majority of dispensed opioid prescriptions (96.2% in 2016). Dispensed benzodiazepine prescriptions increased by 14.6%. CONCLUSIONS: The increase in the consumption of opioids is concerning, suggesting that continuing education is required for dentists to better understand their limited role in managing dental pain and potential for abuse. The substantial increase in the dispensed use of benzodiazepines also requires further investigation and there were some drugs prescribed inappropriately and not in accordance with guidelines. Consideration could also be given to reviewing the drugs listed on the PBS for dental prescribing.

ItemPatterns of use of oral health care services and barriers to dental care among ambulatory older Chilean(BMC, 2017-01-09)BACKGROUND: This paper describes the patterns of use of oral health care services among ambulant 65-74 years or older adults, living in the Maule Region of Chile, factors associated with their use of oral health care services, and self-reported barriers to using oral health care services. METHODS: Four hundred and thirty eight older adults, aged 65-74 years, living independently in the community were orally examined and underwent an oral health interview. Recency of visits was related to the use of oral health care services within the 12 months prior to the study. RESULTS: 31.5% of respondents had used oral health services in the previous 12 months. In multivariate analyses, those living in rural areas (OR = 2.15; 95% CI:1.27-3.63), and those with secondary or higher education (OR = 1.65; 95% CI:1.03-2.64) visited the dentist in the last 12 months in a higher proportion. Those with more filled tooth-surfaces were more likely to have visited the dentist (OR = 4.02; 95% CI;3.58-4.51). Participants who self-reported dental fear, were less likely to have visited the dentist than those who did not (OR = 0.43; 95% CI;0.24-0.76). CONCLUSION: Comparing with existing data in Chile, participants in this study appear to have a slightly lower attendance. Findings question assumptions regarding oral health services utilization by rural residents and highlight the need to identify factors that influence the use of oral health services by older Chileans.

ItemOral cancer screening practices of oral health professionals in Australia(BMC, 2017-12-15)BACKGROUND: To evaluate oral cancer-related screening practices of Oral Health Professionals (OHPs - dentists, dental hygienists, dental therapists, and oral health therapists) practising in Victoria, Australia. METHODS: A 36-item survey was distributed to 3343 OHPs. Items included socio-demographic and work-related characteristics; self-assessed knowledge of oral cancer; perceived level of confidence in discussing oral health behaviors with patients; oral cancer screening practices; and self-evaluated need for additional training on screening procedures for oral cancer. RESULTS: A total of 380 OHPs responded this survey, achieving an overall response rate of 9.4%. Forty-five were excluded from further analysis. Of these 335 OHP, 72% were dentists; (n = 241); either GDP or Dental Specialists; 13.7% (n = 46) were dental hygienists; 12.2% (n = 41) were oral health therapists, and the remaining 2.1% (n = 7) were dental therapists. While the majority (95.2%) agreed that oral cancer screening should be routinely performed, in actual practice around half (51.4%) screened all their patients. Another 12.8% "Very rarely" conducted screening examinations. The probability of routinely conducting an oral cancer screening was explored utilising Logistic Regression Analysis. Four variables remained statistically significant (p < 0.0001). Results indicate that the likelihood of conducting an oral cancer screening rose with increasing levels of OHPs' confidence in oral cancer-related knowledge (OR = 1.35; 95% CI: 1.09-1.67) and with higher levels of confidence in discussing oral hygiene practices with patients (OR = 1.25; 95% CI: 1.03-1.52). Results also showed that dental specialists were less likely to perform oral cancer screening examinations compared with other OHPs (OR = 0.18; 95% CI: 0.07-0.52) and the likelihood of performing an oral cancer screening decreased when the "patient complained of a problem" (OR = 0.21; 95% CI: 0.10-0.44). CONCLUSION: Only half the study sample performed oral cancer screening examinations for all of their patients. This study provides evidence of the need for further oral cancer-related education and screening training for OHPs, which is vital to enhance oral cancer prevention and early detection.

ItemPatient satisfaction with E-Oral Health care in rural and remote settings: a systematic review protocol(BMC, 2017)BACKGROUND: Individuals living in rural and remote settings face oral health problems and access-to-care barriers due to the shortage of oral health care providers in these areas, geographic remoteness, lack of appropriate infrastructure and lower socio-economic status. E-Oral Health technology could mitigate these barriers by providing the delivery of some aspects of health care and exchange of information across geographic distances. This review will systematically evaluate the literature on patient satisfaction with received E-Oral Health care in rural and remote communities. METHODS: This systematic review will include interventional and observational studies in which E-Oral Health technology is used as an intervention in rural and remote communities of any country worldwide. Conventional oral health care will be used as a comparator when provided. Patient satisfaction with received E-Oral Health care will be considered as a primary outcome for this review. Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and Global Health will be searched using a comprehensive search strategy. Two review authors will independently screen results to identify potentially eligible studies and independently extract the data from the included studies. A third author will resolve any discrepancies between reviewers. Two independent researchers will assess the risk of bias and the Grading of Recommendations Assessment, Development, and Evaluation. DISCUSSION: The potential implications and benefits of E-Oral Health care can inform policymakers and health care professionals to take advantage of this technology to address health care challenges in these areas.
