    Abstract Background: Erosive tooth wear has significant impacts on oral and general health. This study aimed to measure the awareness of dental erosion to establish the relationships among sociodemographic factors, awareness and knowledge of dental erosion, and beverage consumption behaviours, in a sample of university students in Australia.
    Methods: All undergraduate students enrolled in the targeted programs at an Australian University were invited. A total of 418 students consented to participate. Each was assessed with an online questionnaire.
    Results: The awareness rate of dental erosion was 92.1%. Soft drinks and fruit juice were most often perceived as acidic beverages by the respondents. The students of greater age, and studying pharmacy, paramedicine, physiotherapy or science, were less likely to be aware of dental erosion. Those students that were aware of dental erosion also had better knowledge of dental erosion, which was associated with a reduced quantity of daily acidic beverage consumption as well. The students that predominantly resided overseas had less knowledge of dental erosion. The students that were of greater age, that were studying clinical science, pharmacy, medical science, paramedicine, or science, and that correctly identified more types of acidic beverages, more often consumed acidic beverages in high-risk patterns.
    Conclusions: Erosive tooth wear is a relevant matter in dentistry, nutrition and public health. Within a university setting, the effect of education on oral health literacy and beverage consumption behaviour is confirmed. Dental and health professionals should actively educate the individuals and communities about dental erosion and motivate them to change acidic beverage consumption behaviours.

    Abstract With a higher pH level and being unlikely to erode the tooth, bottled water has been considered a safe alternative to acidic beverages. However, recent studies have reported some bottled water products in different countries to be acidic. The present paper aimed to examine the pH values of 42 bottled waters commercially available in Australia, using a pH meter and probe, and classify their risks to cause erosive tooth wear in comparison with the critical pH of enamel and dentine. Of the 42 bottled water samples collected, 81.0 and 73.8% were considered erosive to tooth dentine and enamel, respectively. Flavoured waters were the most acidic, followed by sparkling waters, spring waters, artesian waters, mineral waters, and alkaline waters. All sparkling waters and flavoured waters showed an erosive risk to the enamel and dentine. A portion of spring waters and artesian waters was also acidic enough to erode tooth structures. The findings of this work were of concern given the risk of sustaining erosive tooth wear from consuming bottled waters. Health promotion strategies including public awareness and education on oral health consequences related to the consumption of bottled water are needed. Future epidemiological and in vivo investigations are also warranted.

    Abstract Background: Oral health knowledge forms part of oral health literacy that enables individuals to inform appropriate oral health decisions and actions. Oral health-related quality of life (OHRQoL) characterizes self-perception of well-being influenced by oral health. This study aimed to examine the relationship between oral health knowledge and OHRQoL.
    Methods: A random sample of 19-to-24-year-old first-year undergraduate students (n = 372) in Minnesota, United States of America was used. Each student was assessed with an online survey using the Comprehensive Measure of Oral Health Knowledge (CMOHK) and the OHRQoL items of the World Health Organization (WHO) Oral Health Questionnaire for Adults. Relationships between OHRQoL parameters and CMOHK together with other covariates were assessed using ordinal regression models. Associations between OHRQoL parameters were examined with the Kendall's tau-b method.
    Results: Dry mouth (45%) was the most reported OHRQoL issue. The respondents showing good oral health knowledge were less likely to experience speech or pronunciation difficulty (β=-1.12, p = 0.0006), interrupted sleep (β=-1.43, p = 0.0040), taking days off (β=-1.71, p = 0.0054), difficulty doing usual activities (β=-2.37, p = 0.0002), or reduced participation in social activities due to dental or oral issues (β=-1.65, p = 0.0078).
    Conclusions: This study suggested a protective effect of better oral health knowledge on specific OHRQoL issues. In addition to provision of affordable dental services, university-wide oral health education can be implemented to improve OHRQoL in undergraduate students.

    Abstract Objectives: To examine the effect of individualized smartphone-recorded video review on dental student confidence in performing local anesthesia (LA) techniques, in a manikin-based simulation environment.
    Methods: All University of Minnesota second-year dental students were invited to participate in this randomized trial developed following the Consolidated Standards of Reporting Trials statement, in 2020. With a parallel trial design, 104 students were randomly divided into two groups (52 per group) prior to the learning experience. Students and researchers were not blinded to group assignments. All students learned LA techniques in the same manikin-based simulation setting. The experimental group incorporated individualized smartphone filming into simulation training, and the control group did not. A paper-based questionnaire with 19 5-point Likert scale questions assessed the students' self-rated confidence levels in LA techniques before, immediately after, and approximately one month after the training.
    Results: The final sample included 45 students in the experimental group (48.4%) and 48 in the control group (51.6%). In both groups, student confidence in performing LA techniques increased after completion of the training (p < 0.001), with no harm reported. The experimental group reported greater confidence in inferior alveolar nerve injection (p = 0.038), and in local anesthetic administration rate (p = 0.029), compared with the control group.
    Conclusions: This study suggested that the incorporation of smartphone-recorded video review in simulation training is beneficial for learning LA techniques. Further investigation on teaching methods to enhance student confidence and performance in LA administration is indicated.

    Abstract Objective: This study aimed to investigate the prevalence of areca nut consumption and to identify social and behavioural determinants among a Taiwanese adolescent population.
    Subjects and methods: A random sample of 5,343 high school students aged between 15-18 years in Kaohsiung, Taiwan, participated in the study. Participants underwent a clinical dental examination and completed a self-administered questionnaire. Data analyses were performed using multivariate logistic regression to establish a relationship between areca nut consumption as well as social and behavioural characteristics.
    Results: The prevalence of areca nut consumption was 3.0%. The chewing habit was more prevalent among older adolescents (p < .001, OR = 1.50, 95% CI: 1.26, 1.78), males (p < .001, OR = 17.91, 95% CI: 8.57, 37.40), pupils living with non-birth parent(s) (p = .003, OR = 2.13, 95% CI: 1.29, 3.50), children of family heads with primary (p = .001, OR = 2.90, 95% CI: 1.50, 5.59) or secondary level of education (p < .001, OR = 2.78, 95% CI: 1.74, 4.46), frequent risk takers (p < .001, OR = 1.35, 95% CI: 1.27, 1.43) and students of low physical fitness (p < .001, OR = 3.65, 95% CI: 1.81, 7.35).
    Conclusions: Areca nut consumption has become an ongoing pertinent issue in adolescent health. Future investigations into neurocognitive influences of risk-taking behaviour on areca nut consumption and social dependence of the habit are indicated.

    Abstract Background: Non-nutritive sucking habits, bottle feeding, and facial hyperdivergency have been suggested as the influencing factors of anterior open bite (AOB). There was inconsistent reporting of prevalence and a gap of knowledge in the literature.
    Aim: The aim of this study was to investigate the prevalence of AOB in 7- to 12-year-olds, with a special interest to characterise the determinants of this malocclusion.
    Design: A sample of 203 children aged 7 to 12 years were selected from a primary school in regional Australia. The legal guardian of each child completed a self-administered questionnaire. Data were assessed using methods of univariate statistics and neural analysis.
    Results: The prevalence of AOB and thumb sucking was 24.1% and 23.2%, respectively. AOB was associated with the habit (correlation = 0.754) and duration (correlation = 0.574) of thumb sucking. Age, gender, birth order, feeding modality, sleep patterns, history of orthodontic treatment and tonsil, adenoid or grommet surgery, and parents' level of education were not related to AOB (correlation absolute value ≤ 0.474).
    Conclusions: Thumb sucking, specifically for prolonged duration, increases the risk of development of AOB. Cessation of thumb sucking habits should be encouraged at an early age to avoid the development of AOB.

    Abstract Objectives: This study aimed to evaluate the splatter contamination generated by rotary instrumentation and irrigation during simulations of surgical extractions. Specifically, comparisons of the splatters generated were made between traditional assistant-based irrigation and self-irrigating drills and between saline and hydrogen peroxide irrigant.
    Materials and methods: A fluorescein solution was infiltrated into the irrigation system of high-speed drills, and the surgical extraction procedures were performed on manikins with the typodont teeth. Filter papers were placed at the predetermined locations around the operatory to absorb the fluorescein splatters; these samples underwent photographic image analysis.
    Results: The patient chest showed the largest area of splatters, followed by the assistant's face shield. Procedures using the hydrogen peroxide irrigant generated a larger area of splatter than those using the saline irrigant. There was no difference between the splatters produced by assistant irrigation and self-irrigating drill procedures.
    Conclusions: Clinicians should observe and disinfect the locations contaminated by splatters to prevent the spread of infection, since using alternative irrigant or irrigation methods did not reduce the formation of splatters.
    Clinical relevance: Oral surgery drills with irrigation generate aerosols and splatters, which have potential to spread airborne pathogens. It is important to understand the patterns of splatters to mitigate contamination.

    Abstract This study uses a general formulation of integrated visual grading regression (IVGR) and applies it to cone beam computed tomography (CBCT) scan data related to anatomical landmarks for dental implantology. The aim was to assess and predict a minimum acceptable dose for diagnostic imaging and reporting. A skull phantom was imaged with a CBCT unit at various diagnostic exposures. Key anatomical landmarks within the images were independently reviewed by three trained observers. Each provided an overall image quality score. Statistical analysis was carried out to examine the acceptability of the images taken, using an IVGR analysis that was formulized as a three-stage protocol including defining an integrated score, development of an ordinal regression, and investigation of the possibility for dose reduction through estimated parameters. For a unit increase in the logarithm of radiation dose, the odds ratio that the integrated score for an image assessed by observers being rated in a higher category was 3.940 (95% confidence interval: 1.016-15.280). When assessed by the observers, the minimum dose required to achieve a 75% probability for an image to be classified as at least acceptable was 1346.91 mGy·cm

    Abstract Background: Greater awareness and knowledge of oral cancer has been shown to increase patient presentation for opportunistic screening. This study aimed to identify the level of awareness and knowledge of oral cancer amongst adult patients in regional New South Wales.
    Methods: A total of 444 adult dental patients participated in a self-administered questionnaire at one of five regional university dental clinics between 23
    Results: The study revealed that 73.8% of patients were aware of oral cancer; however, only 28.8% knew that they had been previously screened for oral cancer. Being female (P < 0.001, OR = 2.57), having an excellent level of oral health (P = 0.042, OR = 3.34) and previous attendance at a dental clinic of the regional university (P = 0.014, OR = 2.89) significantly enhanced awareness of oral cancer.
    Conclusion: The findings of this study have broad implications for both clinicians and public health professionals, providing a platform for discussion regarding the sociodemographic factors contributing to reduced knowledge and awareness of oral cancer amongst patients. This study also identified an essential avenue to allow a more targeted approach in future campaigns to increase education.

    Abstract Background: This study aimed to investigate dentists' supply and practice patterns following the implementation of the global budget system in Taiwan.
    Materials and methods: Data of reimbursement claims, municipal socioeconomic status and dental manpower were collected from the National Health Insurance administration, the Ministry of Internal Affair, and the Ministry of Health and Welfare, respectively. A multivariate linear regression method was used for data analysis.
    Results: A municipality that reported a higher percentage of tertiary educated population (t = 3.718, P < 0.001), a higher per capita income (t = 6.172, P < 0.001), a higher population density (t = 6.172, P < 0.001), or a lower percentage of elderly population (t = -2.506, P = 0.014) was more likely to have a higher number of dentists per 100,000 population. A municipality that reported a higher Herfindahl-Hirschman Index (HHI) value (t = 2.880, P = 0.005) was more likely to show a higher move-out rate among dentists. The rate was lower after the implementation of the global budget system (t = -2.436, P = 0.018). A municipality that had a higher percentage of elderly population (t = 3.628, P < 0.001), a lower percentage of young population (t = -2.138, P = 0.035), or a higher rate of population growth (t = 4.412, P < 0.001) was more likely to display a higher move-in rate among dentists. The percentage of amalgam restorations in total claims reduced from 19.82% to 17.94%, while the percentage of tooth-colored material restorations increased from 25.46% to 28.79%.
    Conclusion: This study has demonstrated a stabilizing effect of the global budget system on dynamics of dental manpower in Taiwan. A relationship between HHI and dentists' move-out rate has been found. The relationship between municipal socioeconomic status and the density of dentists has also been confirmed. In addition, reduced utilization of amalgam restorations was accompanied by increased utilization of tooth-colored material restorations. Further investigations are indicated.
