Conceptualising the relationships between food sovereignty, food security and oral health among global Indigenous Communities: a scoping review.

OBJECTIVE: Invasive colonial influences and continuing neoliberal policies have a detrimental impact on Land, health, food and culture for Indigenous Communities. Food security and sovereignty have significant impacts on Indigenous well-being and, specifically, oral health. Aspects relating to food security, such as availability of nutritious foods, are a common risk factor of oral diseases. This scoping review aimed to collate existing evidence regarding the relationship between food sovereignty and/or food security and oral health for Indigenous Communities, globally. DESIGN: Four databases were searched using keywords related to 'Food security' or 'Food sovereignty,' 'Indigenous Peoples' and 'Oral health.' Duplicates were removed, and two independent reviewers screened the titles and abstracts to identify articles for full-text review. Extracted data were summarised narratively, presenting a conceptual model which illustrates the findings and relationships between food security and/or food sovereignty and oral health. RESULTS: The search identified 369 articles, with forty-one suitable for full-text review and a final nine that met inclusion criteria. The impact of food security and food sovereignty on oral health was discussed across different populations and sample sizes, ranging from eighteen Kichwa families in Brazil to 533 First Nations and Metis households in Canada. Pathways of influence between food sovereignty and/or food security are explored clinically, quantitatively and qualitatively across oral health outcomes, including early childhood caries, dental caries and oral health-related quality of life for Indigenous Communities. CONCLUSIONS: Innovative strategies underpinned by concepts of Indigenous food sovereignty are needed to promote oral health equity for Indigenous Communities. The nexus between oral health and Indigenous food sovereignty remains largely unexplored, but has immense potential for empowering Indigenous rights to self-determination of health that honour Indigenous ways of knowing, being and doing.

Demystifying the connection between periodontal disease and chronic kidney disease - An umbrella review.

Chronic kidney disease (CKD) and poor oral health are inter-related and their significant impact on each other is well established in the literature. Many systematic reviews and meta-analyses have demonstrated a strong relationship between CKD and periodontitis, where periodontal treatment has shown potential in improving CKD outcomes. However, the quality of the studies and heterogeneity of the results show variation. The aim of this umbrella review was to review the quality of the current systematic reviews on the relationship between CKD and oral health with an emphasis on periodontal disease and to generate clinically relevant guidelines to maintain periodontal health in patients with CKD. This umbrella review was conducted and reported in alignment with the Joanna Briggs Institute and the PRISMA 2020 guidelines. The review protocol was established prior to commencing the review and registered on JBI and PROSPERO (CRD42022335209). Search strings were established for PubMed, Embase, Web of Science, Cochrane Database of Systematic Reviews, and Dentistry & Oral Science Source up to April 2022. All systematic reviews and meta-analyses that considered the relationship between CKD and periodontitis or periodontal treatment were included. Of 371 studies identified through the systematic search, 18 systematic reviews met the inclusion criteria. Ten studies assessed the relationship between oral health status and CKD with a focus on periodontitis and CKD, five reviewed the impact of periodontal treatment on CKD outcomes, two included both relationship and effectiveness of periodontal treatment and one qualitatively reviewed oral health-related quality of life in patients with kidney failure. Findings indicate there is a bidirectional relationship between CKD and periodontal disease. In view of the heterogeneity of the existing literature on CKD and periodontal disease, specific recommendations for the management of periodontitis among patients with CKD are proposed for medical professionals, dental professionals, and aged care workers based on the evidence collated in this review.

Toxicity with proton therapy for oral and/or oropharyngeal cancers: A scoping review.

BACKGROUND: Oral and/or oropharyngeal cancers account for approximately 2% of all malignancies, with variation across age groups, genders, and geographic locations. Treatments for oral and/or oropharyngeal cancers usually consist of a combination of surgical excision most commonly followed by radiotherapy ± chemotherapy and/or immunotherapy/biotherapy depending on the nature of the malignancy. The significant morbidity caused by high-dose radiotherapy to the head and neck region is widely observed. Proton therapy is a promising treatment option that localises a proton beam to direct radiation at a specific target, with reduced irradiation to adjacent structures. METHOD: The objective was to explore the toxicity associated with proton therapy for adults with oral and/or oropharyngeal cancer. Eligibility criteria included full-text articles, English articles, published between up till 7 January 2023. Databases included PubMed, Scopus, Web of Science, Embase, and Scopus. RESULTS: The systematic search identified 345 studies and a total of 18 studies were included after two independent reviewers completed title, abstract, and full-text screening. Included studies were from four countries, and median participant age range was 53.3 to 66 years. The most commonly reported acute toxic effects included dysphagia, radiation dermatitis, oral mucositis, dysgeusia, and alopecia. CONCLUSION: Proton therapy is an evolving cancer treatment technique that has diverse advantages over conventional radiotherapy and chemotherapy. This review provides evidence that supports that proton therapy has an improved acute toxicity profile compared to radiotherapy to treat oral and/or oropharyngeal cancer individuals.

The Global Prevalence and Severity of Dental Caries among Racially Minoritized Children: A Systematic Review and Meta-Analysis.

Racially minoritized children often bear a greater burden of dental caries, but the overall magnitude of racial gaps in oral health and their underlying factors are unknown. A systematic review and meta-analysis were conducted to fill these knowledge gaps. We compared racially minoritized (E) children aged 5-11 years (P) with same-age privileged groups (C) to determine the magnitude and correlates of racial inequities in dental caries (O) in observational studies (S). Using the PICOS selection criteria, a targeted search was performed from inception to December 1, 2021, in nine major electronic databases and an online web search for additional grey literature. The primary outcome measures were caries severity, as assessed by mean decayed, missing, and filled teeth (dmft) among children and untreated dental caries prevalence (d > 0%). The meta-analysis used the random-effects model to calculate standardized mean differences (SMD) and 95% confidence intervals (95% CI). Subgroup analysis, tests for heterogeneity (I2, Galbraith plot), leave-one-out sensitivity analysis, cumulative analysis, and publication bias (Egger's test and funnel plots) tests were carried out. The New Castle Ottawa scale was used to assess risk of bias. This review was registered with PROSPERO, CRD42021282771. A total of 75 publications were included in the descriptive analysis. The SMD of dmft score was higher by 2.30 (95% CI: 0.45, 4.15), and the prevalence of untreated dental caries was 23% (95% CI: 16, 31) higher among racially minoritized children, compared to privileged groups. Cumulative analysis showed worsening caries outcomes for racially marginalized children over time and larger inequities in dmft among high-income countries. Our study highlights the high caries burden among minoritized children globally by estimating overall trends and comparing against factors including time, country, and world income. The large magnitude of these inequities, combined with empirical evidence on the oral health impacts of racism and other forms of oppression, reinforce that oral health equity can only be achieved with social and political changes at a global level.

Non-traumatic emergency department dental visits among patients 0-25 years of age: A systematic review and meta-analysis.

BACKGROUND: Nontraumatic dental conditions (NTDC) that made children attending to emergency departments (EDs) of tertiary hospitals can put significant financial and time strain on hospitals. AIM: The aim of this systematic review and meta-analysis was to calculate the prevalence of paediatric presentations to EDs of tertiary hospitals for NTDC and describe the characteristics of these presentations. DESIGN: A systematic search strategy using PubMed, Embase and Web of Science databases was performed to identify studies quantifying NTDC presentations to EDs of tertiary hospitals from inception through to July 2022. Eligible studies were critically appraised using the Joanna Briggs Institute checklist for studies reporting prevalence. RESULTS: The search identified 31 099 studies, from which 14 were found to meet the inclusion criteria. A random effects model was used for meta-analysis, and the prevalence of NTDC reported through EDs of tertiary hospitals ranged from 52.3% to 77.9%. CONCLUSIONS: Nontraumatic dental conditions, which may be preventable when caused by dental caries, made up a high proportion of dental visits to tertiary hospital EDs. Public health initiatives should be considered to reduce the burden of NTDC on EDs.

Molar-root incisor malformation - a systematic review of case reports and case series.

OBJECTIVES: Molar-root incisor malformation (MRIM) is a seldom reported condition characterised by disturbances in root development of first permanent molars. This systematic review aimed to collate the clinical characteristics of individuals diagnosed with MRIM. MATERIALS AND METHODS: A systematic search strategy using PubMed, Embase, Web of Science, and SCOPUS databases was performed through to March 2023. Inclusion criteria were case reports or case series including a diagnosis consistent with MRIM. Critical appraisal for all included studies utilised the Joanna Briggs Institute (JBI) critical appraisal checklist for case reports and case series and collation of clinical characteristics was performed in JBI System for the Unified Management, Assessment and Review of Information program. RESULTS: The search identified 157 studies from which 35 satisfied the inclusion criteria. After full-text review, a total of 23 papers described the MRIM dental anomaly and were included in this paper. A total of 130 reported cases were retrieved, with age ranging 3-32 years, and males affected 1.16:1 females. Presence of neurological conditions, premature birth history, medication, and surgery within first years of life were synthesised and described. CONCLUSIONS: The aetiology of MRIM is yet to be determined but epigenetic changes from significant medical history in the first years of life are likely to influence the development of this root malformation. First permanent molars were most commonly affected, but clinicians should be aware that permanent central incisors, primary teeth and other permanent teeth may also be affected.

From biocolonialism to emancipation: considerations on ethical and culturally respectful omics research with indigenous Australians.

As part of a (bio)colonial project, the biological information of Indigenous Peoples has historically been under scientific scrutiny, with very limited benefits for communities and donors. Negative past experiences have contributed to further exclude Indigenous communities from novel developments in the field of omics research. Over the past decade, new guidelines, reflections, and projects of genetic research with Indigenous Peoples have flourished in Australia, providing opportunities to move the field into a place of respect and ethical relationships. This review explores the ethical and cultural implications of the use of biological samples from Indigenous communities in biomedical research. A structured framework outlining emerging topics of interest for the development of respectful omics research partnerships with Indigenous Australians is presented. This paper highlights aspects related to Indigenous governance, community and individual consent, respectful handling of biological samples, data management, and communication in order to protect Indigenous interests and rights and to promote communities' autonomy.

The impact of neoliberal generative mechanisms on Indigenous health: a critical realist scoping review.

The pervasive nature and colonial foundations of neoliberalism has significant ramifications for Indigenous health, globally. Not only does neoliberalism undermine Indigenous collectivist values by emphasising personal autonomy, but the exploitation of natural resources has unique implications for Indigenous wellbeing. Therefore, this scoping review aims to synthesise evidence that articulates the impacts of neoliberalism on global Indigenous health inequities. Two reviewers searched PubMed, Embase, Scopus, Web of Science, and ProQuest Central to identify records eligible for inclusion. The search was not restricted by geographic location or language. Using principles of qualitative meta-aggregation, generative mechanism summaries and illustrations were extracted from each of the included articles, synthesised into broader categories, then considered in the context of neoliberal ideologies. The systematic search identified 9952 unique records, of which 38 fully satisfied the inclusion criteria. Findings represented 23 Indigenous communities across 12 countries and considered the impacts of neoliberalism across 16 health outcomes. Eighty-eight generative mechanisms of neoliberalism and 12 generative mechanisms of resistance were extracted from the included articles and mapped against four core principles of neoliberalism: competitive and private markets, reduced public expenditure on infrastructure, personal autonomy, and deregulation that facilitates economic activity. Overwhelmingly, neoliberalism has manifest impacts, through various pathways, on poor health outcomes and experiences for Indigenous communities included in this review. Importantly, Indigenous communities continue to resist the impacts of neoliberalism through advocacy, reclamation of traditional practices, and opposition to industrial development. Consideration and investigation of neoliberal structures and ideologies must become common practice in health equity scholarship. Actors within neoliberal societies must resist dominant epistemological, ontological, and praxiological stances that reinforce the supremacy of colonial values and subalternation of Indigenous ways of knowing, being, and doing to begin effectively addressing Indigenous health inequities.

An update on Heck's disease-a systematic review.

BACKGROUND: Previous research has suggested an ethnic association of Heck's disease with a prominent genetic and familial inheritance pattern, but no systematic review has been reported, which has collected all the evidence in one paper. The aim was estimation of the updated age estimates and gender predilection of this disease and also questioning its proposed link to ethnic and geographical factors. METHODS: Heck's disease from 1966 until present are tabulated, including various descriptive characteristics. After removal of duplicates and adhering to all the inclusion criteria, we shortlisted 95 case reports. The quality assessment of all included studies has been done following STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) guidelines. RESULTS: We found an age range of 3-92 years (mean: 23.1 years) with a male to female ratio of 3:4. Geographical distribution revealed one of the main findings of this study, which was an increased incidence of Heck's disease in the European region. CONCLUSIONS: As already observed and established, there is a much greater prevalence of this disease in the indigenous populations of the world and more research should be encouraged to understand the correct transmission and pattern of spread of this disease.

Oral health promotion and programming provided by Aboriginal Community Controlled Health Organisations in South Australia.

BACKGROUND: Aboriginal Community Controlled Health Organisations (ACCHOs) play a critical role in supporting Aboriginal and Torres Strait Islander health in Australia. This article aims to identify and describe oral health programming and promotion provided by ACCHOs in South Australia. METHODS: All ACCHOs in South Australia were identified through the Aboriginal Health Council of South Australia. A targeted search strategy was designed to include the websites and social media pages (Facebook, Twitter, Instagram) for each organisation. Program characteristics were extracted and summarised, and oral health promotion content was analysed utilising content analysis. RESULTS: Twelve programs were identified across the 12 ACCHOs in South Australia. Of these, seven focused on oral health and five focused on nutrition. Oral health and nutrition information shared online by ACCHOs was extracted and aggregated into oral health and nutrition categories, which included reminders about visiting services, advocacy statements, oral hygiene messaging, appointment availability, education resources, and upcoming community-based activities. CONCLUSIONS: The evidence explored highlights the integral role ACCHOs play in oral health promotion and service delivery. It is critically important that ACCHOs are involved in development and implementation of oral health services to ensure programming reflects community knowledges and is effective in improving oral health equity.

The evolution of the teledentistry landscape in Australia: A scoping review.

INTRODUCTION: There has been a recent surge in the use of teledentistry services in Australia that has paralleled the COVID-19 pandemic. Due to the limited published literature reflecting on this transition, this article employed a systematic scoping review methodology. OBJECTIVE: The objective was to explore the role of teledentistry in the provision of clinical dental services in Australia. DESIGN: Two independent reviewers searched PubMed, Embase, Scopus, Web of Science and grey literature sources to identify literature eligible for inclusion. The search was restricted to Australia and service delivery. Data were categorically synthesised by modalities and reported benefits and limitations; findings were cross-referenced with the COVID-19 pandemic timeline. FINDINGS: The systematic search identified 758 articles, of which 25 met the inclusion criteria. Results highlight a range of service providers and definitions of teledentistry. A shift in modality from asynchronous towards synchronous teledentistry pre- and post-COVID-19 pandemic is detailed. DISCUSSION: Whilst highly useful during the COVID-19 pandemic, teledentistry provides a unique opportunity to continue to increase the accessibility of dental services, especially for patients in rural areas or those who are immunocompromised. CONCLUSION: Clinicians and researchers must consider opportunities to merge existing research with the recent clinical uptake of teledentistry for patients that would benefit from teledental services beyond the COVID-19 pandemic.

A systematic review and meta-analysis of the prevalence of human papillomavirus infection in Indigenous populations - A Global Picture.

BACKGROUND AND AIM: Recent trends have shown a decline in the rates of human papillomavirus (HPV)-associated cervical cancer in the vaccinated population but there has been a spike in the HPV-associated oropharyngeal, anal and penile cancers in the majority of the unvaccinated population which are young and middle-aged males. Indigenous populations at an international level carry a disproportionate burden of most diseases. The aim of this meta-analysis was to ascertain the worldwide prevalence of HPV infection in Indigenous populations stratified by sex and site and to document the most commonly reported HPV types. METHODS: Published articles on HPV infection in Indigenous populations from PubMed, Scopus, EMBASE and Web of Science were systematically searched from inception until 23 December 2019. RESULTS: A total of 41 studies were included in the final analysis. The pooled worldwide prevalence of HPV infection (for both oral and genital sites, both males and females) in Indigenous populations was 34.2% (95% CI: 28.9%-39.8%). Subgroup analysis (geographical) showed that the pooled prevalence for African Indigenous, American Indigenous and Asian-Oceanic Indigenous populations were 33.0% (95% CI: 12.8%-57.1%), 33.0% (95% CI: 27.4%-38.9%) and 33.3% (95% CI: 0.17.5%-51.3%), respectively. CONCLUSION: There are not enough data on the burden of the infection carried by males especially with respect to highly suspicious sites like oropharynx. Also, we conclude an overall high prevalence of HPV infection in the Indigenous populations and increasing their susceptibility to benign and malignant manifestations of HPV.

HPV vaccine: uptake and understanding among global Indigenous communities - a qualitative systematic review.

BACKGROUND: Indigenous populations have a high prevalence of Human Papillomavirus (HPV) infection and a high incidence of HPV associated cancers, such as cervical and oropharyngeal cancer. There is an effective HPV vaccination program in almost all developed countries to prevent the incidence of cervical cancer, but reports suggest that the uptake of these vaccinations by Indigenous populations is low. The objective of this qualitative systematic review was to explore the knowledge and beliefs of global Indigenous populations regarding HPV vaccines. This review was performed to identify the barriers faced by Indigenous peoples and to provide evidence for more effective and acceptable execution of vaccination policies for Indigenous peoples. METHODS: Two investigators independently searched MEDLINE, PubMed, SCOPUS, and Web of Science databases using a pre-specified search strategy to identify qualitative studies on narratives of Indigenous peoples regarding HPV vaccine awareness, knowledge and experiences across all geographic and income-level settings. RESULTS: After performing the literature search and quality appraisals 5 papers were included in the final review. Three core synthesised findings were identified: reasons for acceptance or hesitancy, and areas for improvement. Lack of correct knowledge and mistrust in the healthcare system were important categories observed in all papers included in the review. Other categories within the conceptual model included prioritising disease prevention, health professional guidance, family support and supportive community environment. CONCLUSION: Qualitative systematic reviews are an excellent means of exploring the gaps in current healthcare practices. Indigenous healthcare research should be grounded in community experiences and feedback. This review provides insights into HPV vaccination understanding and acceptance amongst Indigenous populations, from which recommendations for increasing resonance of vaccination strategies with Indigenous communities can be formed.

Histopathological Factors in Oral Squamous Cell Carcinoma-Should a Clinician Look Beyond Clinical Staging?

PURPOSE: Several researchers have proposed and investigated the prognostic implications of various parameters, but have failed to provide concrete evidence regarding the inclusion or exclusion of histopathological features while clinically managing an oral squamous cell carcinoma (OSCC) case. The study purpose was to measure the prognostic values of a set of key histologic features and its association with its clinical outcome-5-year survival. MATERIALS AND METHODS: This is a prospective cohort study and the sample was composed of patients treated for OSCC (April 2014 - March 2015). The predictor variables included pattern of tumor invasion (POI), stromal inflammation, angiogenesis, and vascular invasion with the outcome being survival of subjects observed over this 5-year period. Sociodemographic data (age, sex, marital status, systemic disease, habits etc), clinical staging and TNM staging were also recorded. We used multivariate regression analysis for predictor analysis; Kaplan-Meier survival curves and Cox hazard modeling was also performed using the data. RESULTS: This article includes 50 subjects with a mean age of 54.94 years and 58% were male and their characteristics collected at the baseline and at a 12-, 24-, 36-, 48-, and 60-month follow-up. The overall 5-year survival was 48%. We saw a significant association between N-stage and POI (0.027), T-stage and mean vascular density (0.042), and T-stage and vascular invasion (0.046). POI, angiogenesis, and vascular invasion were found as significant predictors of overall 5-year survival (P < .001). CONCLUSIONS: This study shows that histopathological parameters such as POI are important while determining the clinical outcome of OSCC. Histopathological parameters such as angiogenesis and vascular invasion can provide valuable information about the overall survival and prognosis.

Poor Self-Rated Sleep Quality and Quantity Associated with Poor Oral Health-Related Quality of Life among Indigenous Australian Adults.

BACKGROUND: Indigenous Australians score worse on both sleep and oral health. This study aimed to evaluate sleep quality and quantity associated with oral health-related quality of life (OHRQoL) among Indigenous Australian adults. METHODS: A cross-sectional study involving 728 Indigenous Australian adults aged 18+ years was conducted. Exposure variables were sleep quality and quantity. The primary outcome variable was Oral Health Impact Profile-14 (OHIP14), which has been used to assess OHRQoL. Multivariable log-Poisson regression models were applied to estimate the mean ratios (MRs) for mean OHIP14 scores. RESULTS: The average OHIP14 score was 14.9, and the average amount of sleep was 6.8 h/night. After adjusting for all covariates, self-rated very bad sleep quality was associated with 2.2 times (MR = 2.17, 95% CI: 1.97-2.37) higher OHIP14 scores than those who rated their sleep quality as very good. Participants who self-reported sleeping 7-8 h/night had 0.9 times (MR = 0.89, 95%CI: 0.83-0.95) lower OHIP14 scores than those sleeping more than 8 h. CONCLUSIONS: The average number of sleep hours for Indigenous participants were lower than recommended (7-8 h/night). Our findings indicate that poor sleep quality and quantity, and oral health-related behaviours associated with sleep deprivation were positively associated with poor oral health related quality of life among Indigenous Australian adults.

Association of Human Papillomavirus Infection with Tonsillar Cancers: A Systematic Review.

Vaccinations have shown a decrease in human papillomavirus (HPV) infection-related cervical cancer in women, but there has been a sharp rise in the HPV infection-related oropharyngeal cancer cases over the past few decades. Recent studies have suggested the association of HPV infections with tonsillar cancers as well and suggestions regarding preventive tonsillectomies in order to achieve a decrease in HPV infection-related oropharyngeal or tonsillar cancer have arisen. However, there is limited cumulative evidence validated at a global level to support the endorsement of this strategy. This research revolves around the concept of burden of tonsillar carcinomas due to oropharyngeal HPV infection. Thus, a systematic review and meta-analysis of existing studies was undertaken to estimate the pooled prevalence of tonsillar cancer associated with oropharyngeal HPV infection. Published articles on tonsillar cancer with and without HPV infection from PubMed, Embase, Scopus and Web of Science were systematically searched from inception until 23 December 2021. A random-effects model was used to estimate the pooled prevalence forest plots. The systematic review revealed that 50% of the reported cases of tonsillar cancer had an oropharyngeal HPV infection, questioning the preventive nature of an early tonsillectomy which is essentially an invasive surgical procedure. Large heterogeneity was reported in the included studies, and there was insufficient data for sub-group analysis. Future research and representative studies are required to thoroughly explore the correlation between HPV infection and tonsillar cancer.

Knowledge and Awareness of HPV, the HPV Vaccine and Cancer-Related HPV Types among Indigenous Australians.

Human Papilloma Virus (HPV) infection is a common, preventable, sexually transmitted disease with oncogenic potential and increasing incidence. This study aimed to gain an understanding of the knowledge and awareness of HPV, the HPV vaccine, and HPV-related cancers, and to evaluate the relationship between participant factors and HPV knowledge, vaccination uptake, and high-risk HPV (16/18) infection, among Indigenous Australians. Data from the 12-month follow-up of a longitudinal cohort study were utilized, involving 763 Indigenous Australian adults in South Australia. The data analysis found that the mean 7-item HPV knowledge tool (HPV-KT) score was 2.3 (95% CI: 2.1-2.4), HPV vaccination prevalence was 27.0% (95% CI: 23.6-30.5) and oral HPV 16/18 infection was 4.7% (95% CI: 3.2-6.2). Multivariable log-Poisson regression models showed ratios of approximately 1.5 times higher HPV-KT scores in females, previous recreational drug users, those who had self-rated as having excellent, very good or good general health and who had heard of HPV; and participants who were not HPV vaccinated had 0.8 times (MR = 0.8, 95% CI: 0.7-0.9) lower HPV-KT scores than their counterparts. The findings suggest that culturally safe education strategies are a necessary investment to improve vaccination coverage among Indigenous Australians and to reduce the impact of HPV and related cancers.

Cephalometry as an aid in the diagnosis of pediatric obstructive sleep apnoea: A systematic review and meta-analysis.

Background: Obstructive sleep apnoea (OSA) is part of a spectrum of sleep disorders causing snoring, gasping, and choking while sleeping. In children, OSA can also lead to behavioural issues, hyperactivity, and poor academic performance. Thus, early identification and management of OSA in children is crucial in preventing long-term health problems. The gold standard test for diagnosis is an overnight in-lab polysomnography (PSG). However, due to certain constraints associated with PSG, such as lack of accessibility, high expenses incurred, as well as the need for hospitalization, alternative diagnostic tools are needed. Cephalometry is a non-invasive, affordable diagnostic tool that may offer useful information in the evaluation of OSA. The present systematic review and meta-analysis aimed to evaluate the various cephalometric parameters associated with the diagnosis of OSA in children. Methods: A structured literature search was performed using the search engines PubMed, Scopus, Web of Science, Cochrane, and Google scholar from inception till July 2022. The weighted mean difference (z-test) was calculated using a random effects method (REM). Results: 16 studies were included in the review and meta-analysis was executed for each cephalometric parameter. The parameters of significance (p < 0.05) in Pediatric OSA with lower heterogeneity were associated with McNamara's and Linder-Aronson's analysis, the hyoid bone position, a retrognathic mandible, and an acute cranial base angle. Conclusions: Certain parameters in craniofacial morphology may be reliable diagnostic parameters. Further long-term studies are needed in order to shed more light in this area.

Effect of sleep on oral health: A scoping review.

Sleep is a vital biological process that facilitates numerous vital functions integral to mental and physical restoration of the body. Sleep deprivation or poor sleep quality not only affects physical health but may also affect oral health. This scoping review aims to collate existing evidence related to the impact of sleep duration and/or quality on oral health. A systematic search strategy using PubMed, Embase, Scopus and CINAHL databases was performed to identify studies that assessed the association between sleep quality or duration and oral health or hygiene. Two researchers independently screened and extracted the data. Eligible studies were critically appraised using the NIH quality assessment tool for observational cohort and cross-sectional studies checklist. The search identified 18,398 studies, from which 14 fulfilled the inclusion criteria. Of the 14 papers, four papers were associated with effect of sleep on caries, 8 papers described the effect of sleep on gingival and periodontal health, and two papers described the effect of sleep on general oral health and oral disease symptoms. This review found a direct link between sleep and dental decay in children, and short sleep duration was associated with an increased risk of periodontitis adults.
