The Tanaka and Johnston mixed dentition analysis is a widely used method to predict the size of unerupted permanent canines and premolars. The aim of the present study was to determine the applicability of the Tanaka and Johnston analysis to Western Australian adolescents and develop a new regression equation.

Background: Persons with disabilities (PWDs) face significant barriers in accessing dental care, resulting in poorer oral health outcomes compared to the general population. To reduce dental healthcare disparities, dental professionals must develop positive attitudes and acquire the necessary skills to treat PWDs effectively. This study aimed to assess the experiences, education, training levels, and attitudes of dental students and interns toward PWDs, and to explore the relationships between their exposure to PWDs, their education/training regarding managing PWDs, and their attitudes toward PWDs. Methods: Participants were recruited using convenience sampling. From May to June 2023, a pretested, validated online questionnaire (developed based on existing survey instruments and modified to fit the study context) was distributed to 98 eligible dental students and interns at King Faisal University. Descriptive and analytical statistics were used for analysis. Results: The response rate was 88.78%. There was a statistically positive correlation between students' exposure to PWDs and their attitudes (p < 0.05). Statistically significant relationships were found between students' education/training and their attitudes towards educational experiences and instructors (p < 0.01) and interpersonal interactions with PWDs (p < 0.05). No statistically significant relationship existed between the year of study and future encounters with PWDs (p = 0.176). Additionally, 42.5% of students felt inadequately prepared to treat PWDs, and 88.5% expressed a desire for further education. Notably, 20.7% reported no training on PWDs, while 70.1% preferred clinical education. Conclusions: The study underscores the importance of exposure and training in shaping dental students' attitudes toward PWDs. Dental schools should prioritize structured teaching, greater contact with the disabled community, and hands-on experiences to ensure dental professionals are both well prepared and positively inclined to treat PWDs. These findings have significant implications for improving dental education curricula. [ABSTRACT FROM AUTHOR]

Objective: This systematic review aimed to comprehensively summarize and critically assess studies conducted on oral health outcomes among individuals with cerebral palsy (CP) in Saudi Arabia. Methods: This study followed the Participants, Exposure, Control and Outcomes (PECO) framework to formulate a focused research question. We conducted an extensive literature search across multiple databases, including PubMed, Medline, Scopus and Embase, in addition to clinical trial registers. Inclusion criteria encompassed clinical studies conducted in either English or Arabic, focusing on CP as defined by the International Classification of Diseases 10 (ICD10), and examining various oral health conditions and parameters. Nonclinical studies, commentaries, other systematic reviews and letters to the editor were excluded. Data extraction included comprehensive information about the study characteristics, oral health outcomes (dental, oral or periodontal disease; changes in standardized indices; dental trauma and other types of oral diseases) and an assessment of the risk of bias using the Appraisal Tool for Cross‐Sectional Studies (AXIS). Results: The initial search yielded a total of 879 articles, ultimately resulting seven studies that met our stringent inclusion criteria. All of these studies were conducted as cross‐sectional investigations in different cities within Saudi Arabia. The sample sizes ranged from 46 to 400 participants, all falling within the age range of 2–18 years. Notably, the prevalence of dental caries among individuals with CP in these studies varied significantly, with rates ranging from 52.9% to as high as 98.6%. Additionally, a substantial portion of CP patients exhibited poor oral hygiene, with figures ranging between 34.6% and 66.2%, and dental trauma was reported in 47.5% of the cases. Moreover, these studies underscored the influence of motor function and intellectual disabilities on the oral health status of CP individuals. Furthermore, various secondary outcomes, including periodontal parameters and oral health‐related quality of life, were also assessed. However, it is essential to acknowledge that several sources of bias were identified within these studies, raising questions about the generalisability of their findings. Conclusion: In conclusion, the systematic review revealed a concerning pattern of high dental caries prevalence and other oral health issues among individuals with CP in Saudi Arabia. Nevertheless, the need for comparative studies between CP patients and those without CP is evident to establish a definitive understanding of the oral health status of CP individuals. Initiating early interventions such as oral hygiene education, preventive dentistry programs, and orthodontic interventions could potentially contribute to improved oral health outcomes for individuals with CP in Saudi Arabia.

Oral cancer is a malignant neoplasia that can originate in the oral cavity or lips. It is a serious global health problem and one of the ten most common cancers worldwide. Over the years, changes in the trends of the oral cavity and oropharyngeal cancers have been observed. The management of oral cancer is complicated due to the functional and cosmetic consequences of treating malignancies at these anatomical locations. The tumor and its treatment can affect a variety of functional activities, including smell, sight, speaking, respiration, taste, jaw function, and mastication, either temporarily or permanently. Based on the importance of this tumor, screening oral cancer for early detection and finding the best biomarkers for diagnosis is a crucial concern. In this review of literature, the etiology, risk factors, treatment, and diagnosis of oral cancer will be reviewed with a focus on the most important biomarkers. [ABSTRACT FROM AUTHOR]

Background/Aim: This retrospective study investigated the effect of lockdowns for Covid‐19 on the rates of oro‐facial trauma hospitalisations in children in Australia and the United Kingdom (UK). Materials and Methods: Hospitalisation data for children up to 19 years old for oro‐facial trauma injuries (according to ICD‐10‐AM principal diagnosis codes) over 5 years were collected for Australian and UK children. The age‐standard rate (ASR) for each age group was calculated per 100,000 population. Results: In the younger Australian children, there was no statistically significant change in the ASR of oro‐facial trauma hospitalisations during the 'Covid year', compared to the average rate over the 3 years preceding. However, there was a significant decrease in the ASR of oro‐facial trauma hospitalisations during the 'Covid year' in older Australian children (aged 10–19), and for all UK children, except for infants under one‐year‐old. Conclusions: Reduction of the ASR of hospitalisations due to oro‐facial trauma during the 'Covid year', and the implementation of lockdown measures in the two countries provides further evidence of the impact of physical activities and travel as contributing factors to oro‐facial injuries in children. In addition to its role in reducing the spread of virus infections during the pandemic, the lockdown measures also resulted in a simultaneous decrease in trauma injuries. [ABSTRACT FROM AUTHOR]

Objectives: Aboriginal and Torres Strait Islander communities in remote parts of Australia are some of the most underserviced communities in regard to oral health care. These communities rely on volunteer dental programmes such as the Kimberley Dental Team to fill the gaps in care, however, there are no known continuous quality improvement (CQI) frameworks to guide such organizations to ensure that they are delivering high‐quality, community‐centred, culturally appropriate care. This study proposes a CQI framework model for voluntary dental programmes providing care to remote Aboriginal communities. Methods: Relevant CQI models wherein the (i) behaviour of interest was quality improvement, and (ii) the health context was volunteer services in Aboriginal communities were identified from the literature. The conceptual models were subsequently augmented using a 'best fit' framework and the existing evidence synthesized to develop a CQI framework that aims to guide volunteer dental services to develop local priorities and enhance current dental practice. Results: A cyclical five‐phase model is proposed starting with consultation and moving through the phases of data collection, consideration, collaboration and celebration. Conclusions: This is the first proposed CQI framework for volunteer dental services working with Aboriginal communities. The framework enables volunteers to ensure that the quality of care provided is commensurate with the community needs and informed by community consultation. It is anticipated that future mixed methods research will enable formal evaluation of the 5C model and CQI strategies focusing on oral health among Aboriginal communities. [ABSTRACT FROM AUTHOR]

Background: The accessibility to affordable primary healthcare services contributes to population health and health equity. A key aspect to accessibility is the geographical distribution of primary healthcare services. Limited studies have assessed the nationwide spatial distribution of bulk billing-only medical practices or 'no-fee' services. The aim of this study was to provide a nationwide approximation of bulk billing-only services and evaluate the socio-demographic status and population characteristics in relation to the distribution of bulk billing-only GP services. Methods: The methodology in this study used Geographic Information System (GIS) technology to map the locations of all bulk bulking-only medical practices collected in mid-2020 and linked this with population data. The population data and practice locations were analysed at the level of Statistical Areas Level 2 (SA2) regions and used the most recent Census data. Results: The study sample included (n = 2095) bulk billing-only medical practice locations. The nationwide average Population-to-Practice (PtP) ratio was 1 practice to 8529 people for regions with access to bulk billing-only practice, and 57.4% of the Australian population lives within an SA2 that has access to at least one bulk billing-only medical practices. No significant associations were identified between practice distribution and area socio-economic status. Conclusion: The study identified areas with low access to affordable GP services, with many SA2 regions having no access to bulk billing-only practices. Findings also indicate that there was no association between area socio-economic status and the distribution of bulk billing-only services. Inadequate subsidisation of the Medicare rebate threatens the survival of bulk billing only GP services. Little is known of the socio-economic status of bulk billing only practice localities and whether they target disadvantaged populations. This research provides a current estimation of the distribution of bulk billing only GP services in Australia in relation to surrounding population socio-economic demographics.

Aims: To describe the involvement and need for specialists in special needs dentistry (SND) in the multidisciplinary management of patients and to characterize the complexity of patients with special health care needs. Methods: Referrals for SND review from the Fiona Stanley Hospital head and neck cancer (HNC) multidisciplinary team between January 1 and December 31, 2019 were screened. Data recorded included demographic information, medical history, dental status, and dental treatment provided prior to HNC management. Results: In total 127 patients were referred to the SND clinic in 2019 of which 89.0% were males and 74.8% were aged 50–79. The mean waiting time for SND review was 19.6 days. On average patients had a decayed, missing, filled tooth (DMFT) score of 20.3. During the study period 407 extractions and 30 restorations were completed. Seventeen patients (13.4%) had all their teeth removed prior to HNC management. The majority of patients (79.6%) were categorized as either moderate or severe complexity. Increasing complexity was seen in older age groups. Conclusions: Significant oral disease is seen in patients with HNC often requiring extensive dental treatment. Complexity is seen in patients requiring multidisciplinary care however characteristics that constitute complexity are varied given the spectrum encompassing 'special needs'. [ABSTRACT FROM AUTHOR]

Dental caries remains the most common chronic disease in childhood, affecting almost half of all children globally. Dental care and examination of children living in remote and rural areas is an ongoing challenge that has been compounded by COVID. The development of a validated system with the capacity to screen large numbers of children with some degree of automation has the potential to facilitate remote dental screening at low costs. In this study, we aim to develop and validate a deep learning system for the assessment of dental caries using color dental photos. Three state-of-the-art deep learning networks namely VGG16, ResNet-50 and Inception-v3 were adopted in the context. A total of 1020 child dental photos were used to train and validate the system. We achieved an accuracy of 79% with precision and recall respectively 95% and 75% in classifying 'caries' versus 'sound' with inception-v3. [ABSTRACT FROM AUTHOR]

Objectives: It is well known that there are associations between overall health, age, socioeconomic status and rural residency. The objective of this study was to determine the distribution of Australia's aged population by socioeconomic status, as well as remoteness. Methods: The study employed the Australian Statistical Geography Standard (Statistical Area Level 1 and Remoteness Areas). The database of the geographic boundaries was integrated into the ageing population and socioeconomic data using the Geographic Information System. The socioeconomic data was analysed through the Index of Relative Socioeconomic Disadvantage. Results: Over a decade, the older population in Australia has increased noticeably. In 2016, there was a high percentage of older people (≥65 years) in Tasmania (Tas), 19%, while the lowest percentage was recorded in the Northern Territory (NT), 7%. Across the country, Tasmania had the highest percentage of older citizens living in the most disadvantaged areas since 2006, with 48% recorded in 2016. There was an association between the remoteness areas and the education and income levels of the ageing cohort. However, this association differed between the states and territories. This socioeconomic gap becomes more evident in the very remote areas of the country. Conclusions: The ageing population in Australia is increasing rapidly; this was associated with an evolving socioeconomic disparity among this ageing society. Our results demonstrated that socioeconomic inequalities were to be found among the older people based on their distribution over the remoteness areas in Australia. This information should be used to target healthcare and ageing policies that meet the specific needs of older people. [ABSTRACT FROM AUTHOR]
