Introduction: Understanding dental therapy practice across clinical settings is useful for education and service planning. This study assessed if dental therapy service provision varied according to practitioner and workplace characteristics., Methods: Members of professional associations representing dental therapists (DT) and oral health therapists (OHT) were posted a self-complete survey collecting practitioner and workplace characteristics, together with clinical activity on a self-selected typical day of practice. Differences in service provision according to characteristics were assessed by comparing mean services per patient visit. Negative binomial regression models estimated adjusted ratios (R) of mean services per patient., Results: The response rate was 60.6%. Of practitioners registered as an OHT or a DT, 80.0% (n = 500) were employed in general clinical practice. Nearly one-third of OHT and nearly two-thirds of DT worked in public sector dental services. Patterns of service provision varied significantly according to practice sector and other characteristics. After adjusting for characteristics, relative to private sector, public sector practitioners had higher provision rates of fissure sealants (R = 3.79, 95% confidence interval [95% CI]: 2.84-5.06), restorations (R = 3.78, 95% CI: 2.94-4.86) and deciduous tooth extractions (R = 3.58, 95% CI: 2.60-4.93) per patient visit, and lower provision rates of oral health instruction (R = 0.86, 95% CI: 0.76-0.98), fluoride applications (R = 0.43, 95% CI: 0.33-0.56), scale and cleans (R = 0.39, 95% CI: 0.34-0.45) and periodontal services (R = 0.20, 95% CI: 0.14-0.28) per patient visit., Conclusion: Differences in service provision according to sector indicate that OHT and DT adapt to differing patient groups and models of care. Variations may also indicate that barriers to utilising the full scope of practice exist in some settings., (© 2018 FDI World Dental Federation.)

Objectives: To investigate associations of dental knowledge with dental service utilization over 2 years in South Australians aged 45-54 years., Methods: In 2004-2005, a random sample of 2469 adults aged 45-54 years from Adelaide, South Australia, who were selected from the Australian electoral roll was surveyed. The outcome variables were the numbers of visits and dental services received over 2 years. Data were analysed using log-binomial and Poisson regression. Statistical significance was determined at P < .05., Results: The response rates were 43.8% in the study group (n = 879) and 50.7% in the comparison group (n = 107). Oral examinations were conducted on 709 persons (81% of study group participants). Dental services data were collected from approximately 60% of participants at the end of years 1 and 2. After adjusting for sex, education, health card status, toothbrushing and inadequate dentition, higher caries knowledge and periodontal knowledge scores were associated with higher percentages of persons making dental visits (prevalence ratio, 95% CI: 1.2, 1.1-1.3 and 1.1, 1.0-1.3), and lower rates of extraction (rate ratio, 95% CI: 0.2, 0.1-0.4 and 0.4, 0.3-0.7) and endodontic services (0.5, 0.3-0.9 and 0.5, 0.3-0.7). Higher caries knowledge was associated with lower rates of fillings (0.8, 0.7-0.9) and denture services (0.1, 0.0-0.6), while higher periodontal knowledge was associated with higher numbers of visits (1.3, 1.2-1.5), and prophylaxis services (1.4, 1.1-1.8) and crowns (1.7, 1.1-2.5)., Conclusion: South Australians aged 45-54 years with higher dental knowledge had lower rates of invasive treatment over 2 years. These findings warrant policy initiatives that highlight the importance of dental knowledge in improving oral health., (© 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: Dental service provision rates are necessary for workforce planning. This study estimates patient and service rates for oral health therapists (OHTs), dental hygienists (DHs) and dental therapists (DTs). To identify important variables for workforce modelling, variations in rates by practice characteristics were assessed., Design: A cross-sectional self-complete mailed questionnaire collected demographic and employment characteristics, and clinical activity on a self-selected typical day of practice., Setting: Private and public dental practices in Australia., Participants: Members of the two professional associations representing DHs, DTs and OHTs., Methods: For each practitioner type, means and adjusted rate ratios of patients per hour, services per visit and preventive services per visit were estimated. Comparisons by practice characteristics were assessed by negative binomial regression models., Results: Response rate was 60.6% (n = 1,083), 90.9% were employed of which 86.3% were working in clinical practice and completed the service log. Mean services per patient visit provided by OHTs, DHs and DTs were 3.7, 3.5 and 3.3 and mean preventive services per patient were 2.1, 2.1 and 1.8 respectively. For all three groups, adjusting for explanatory variables, the rate of preventive services per patient varied significantly by practice type (general or specialist) and by the proportion of child patients treated., Conclusion: Services rates varied by age distribution of patients and type of practice. If these factors were anticipated to vary over-time, then workforce planning models should consider accounting for the potential impact on capacity to supply services by these dental workforce groups.

Objectives: To determine factors associated with routine dental attendance in Aboriginal Australians., Methods: Data of 271 Aboriginal adults residing in Australia's Northern Territory were used. Routine dental attendance was defined as last visiting a dentist less than one year ago or visiting a dentist for a check-up. Both bivariate and multivariable analytical techniques were used., Results: While 27% visited a dentist in the past year, 29% of these visited for a check-up. In bivariate analysis, being female, low psychological distress, and low clinical attachment loss (CAL) were associated with visiting a dentist within last year. Being aged younger than 39 years, male, no oral health impairment, being caries-free, low CAL, and low apolipoprotein B were associated with visiting for a check-up. Clinical attachment loss remained associated with visiting a dentist less than one year ago while being younger than 39 years and having no oral health impairment remained associated with usually visiting for a check-up in multivariable analysis., Conclusions: Younger age, no oral health impairment, and low CAL were associated with routine dental attendance among Indigenous Australians.

Background: Few studies have examined dental caries experience in Aboriginal adults. The objectives of this study were to describe the dental caries experience of some Aboriginal Australian adults residing in the Northern Territory, and to determine associations with dental caries experience.Methods: A convenience sample of Aboriginal adults from Australia's Northern Territory was dentally examined. Self-reported oral health information was collected through a questionnaire.Results: Data were available for 312 participants. The per cent of untreated decayed teeth (per cent DT >0) was 77.9 (95% CI 73.0 to 82.1), the mean DT was 3.0 (95% CI 2.6 to 3.4), the prevalence of any caries experience (the per cent DMFT >0) was 95.5 (95% CI 92.6 to 97.3) and the mean DMFT was 9.7 (95% CI 8.9 to 10.5). In multivariable analyses, unemployment and not brushing teeth the previous day were associated with the per cent DT >0. Problem-based dental attendance was associated with both the mean DT and the per cent DMFT >0. Older age, residing in the capital city, being non-incarcerated, last visiting a dentist <1 year ago and problem-based dental attendance were associated with the mean DMFT.Conclusions: Dental caries experience among this convenience sample of Aboriginal Australian adults was very high. Most factors associated with dental caries were social determinants or dental service access-related. [ABSTRACT FROM AUTHOR]

Background: Dentine hypersensitivity is a frequent clinical presentation though inadequately comprehended by dentists. The objective of this study was to describe Australian dentists’ perception on the occurrence, predisposing factors, triggers, diagnosis and management of dentine hypersensitivity. Methods: Eight hundred dentists were randomly selected using the Australian Dental Association membership list and invited to participate in a questionnaire-based survey. Results: Out of 295 responding dentists, 284 private practitioners were included in the final analysis. Most dentists perceived that the occurrence of dentine hypersensitivity was <20% and commonest among 30–49 year olds. According to them, abrasion and gingival recession were the main predisposing factors whilst cold stimuli were the commonest trigger. A differential diagnosis-based approach was adopted by a majority to diagnose dentine hypersensitivity although routine screening was resorted to by a few. Most dentists were aware of the current mechanisms underlying dentine hypersensitivity whereas the majority perceived that ongoing predisposing factors was the main reason for dentine tubules to remain exposed. The commonest management strategy employed by most dentists was to prescribe desensitizing agents for home use. Conclusions: Australian dentists’ perception of dentine hypersensitivity is generally consistent with the current scientific consensus on this subject. [ABSTRACT FROM AUTHOR]
