Primary caregivers' perceptions of factors influencing preschool children's oral health: social practices perspective

Publisher: BMJ

Date: 04-2023

DOI: 10.1136/BMJOPEN-2022-068444

Abstract: The role of primary caregivers in setting the foundation for a child’s oral health throughout life is well recognised. Due to the dominant behaviour-based approach, research to date has mainly focused on exploring in idual primary caregivers’ oral health knowledge and behaviours. A social science approach involving social practice theories moves beyond in idual attitudes, behaviour and choices to offer a better understanding of the ways in which collective activity relates to health. This qualitative metasynthesis will involve an interpretive synthesis of data found in published qualitative literature from developed countries. The aim of the metasynthesis is to identify social practices in families from published qualitative research with caregivers on preschool children’s oral health. This is a protocol for qualitative metasynthesis. The following databases will be used: MEDLINE, EMBASE, Global Health and Dentistry & Oral Sciences Source (DOSS) using the web-based database search platform Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus. The research team has determined search strategies by using relevant key terms. Qualitative studies published in English language on family factors related to preschool children (aged 0–5 years) from developed countries (2022 United Nations classification) will be included. Qualitative data analysis will involve thematic analysis of the reported factors influencing oral health of preschool children, from the perspective of social practice theory. Researchers will use NVivo software for organising and managing the data. No ethics approval is required, as this study does not involve human subjects. Findings will be disseminated through professional networks, conference presentations and submission to a peer-reviewed journal.

Economic Evaluations of Preventive Interventions for Dental Caries and Periodontitis: A Systematic Review.

Publisher: Springer Science and Business Media LLC

Date: 12-09-2022

DOI: 10.1007/S40258-022-00758-5

Abstract: To critically examine the methods used for full economic evaluations of preventive interventions for dental caries and periodontitis. Published literature post-2000 was searched to April 2021. Based on a developed intervention classification framework for dental caries and periodontitis, only universal, selective or indicated interventions were included in this review. The Drummond 10-point checklist was used for quality appraisal. Of 3,007 unique records screened for relevance, 73 studies were reviewed. Most model-based studies (61/73) used cost-effectiveness analysis (49%) or cost-benefit analysis (28%). Trial-based studies (16/73) commonly used cost-effectiveness analysis (59%). Four studies used both economic evaluation methods. Sixty-four papers (88%) were on dental caries, eight papers (11%) focused on periodontitis, and one paper (1%) included both oral diseases 72% of model-based and 82% of trial-based studies were of good quality. The most frequently investigated dental caries preventive interventions were water fluoridation (universal intervention cost-saving or cost-effective), fissure sealant and fluoride varnish (selective and indicated interventions cost-effectiveness outcomes were inconsistent). Supportive periodontal therapy with oral health education (indicated intervention cost-effective) was the most frequently evaluated preventive intervention for periodontitis. Thirty percent of studies with a time horizon > 1 year did not apply an appropriate discount rate and 26% did not comprehensively discuss other important considerations beyond the technical analysis. Generic health outcome measures should be incorporated for economic evaluations on preventive interventions for dental caries and periodontitis, and an increased focus to prevent periodontitis using economic evaluation methods is needed to inform resource allocation and policy decision-making.

Abstract: To evaluate the impact of an intervention consisting of a 1-day continuing professional development (CPD) education programme on the International Caries Classification and Management System (ICCMS A quasi non-randomized controlled trial with convenience s ling method was adopted. Fourteen dental practitioners received the intervention. The prevalence of dental caries and gingivitis in Australian children was used to determine the treatment demand and used as the performance benchmark. Ten types of preventive and non-preventive dental services were examined. A Difference-in-Differences (DiD) of 12-month pre- (baseline) and post-intervention analysis was performed. The intervention group demonstrated increases in topical fluoride application and dietary analysis and advice services. The standard care group had increases in oral prophylaxis or scale and clean, topical fluoride application and oral hygiene instructions (p-value <0.05). The DiD analysis confirmed the above findings in the intervention group, while other preventive services declined. In the intervention group, the performance benchmark for oral prophylaxis or scale and clean and oral hygiene instructions was met at baseline and post-intervention. Only a few preventive services had already met the performance benchmark. The intervention was associated with varied changes to preventive and non-preventive dental services. More robust study design addressing the study limitations and validating the performance benchmark is required.

Social practice theory: An innovative approach to considering preschool children’s poor oral health

Publisher: Wiley

Date: 13-05-2021

DOI: 10.1111/CDOE.12659

Abstract: Oral disease in early childhood is highly prevalent and costly and impacts on the child and family with significant societal costs. Current approaches have largely failed to improve young children's oral health. This paper proposes a different approach to conceptualize poor oral health in preschool children (0‐5 years) using social practices. Social practice theory offers an innovative perspective to understanding oral health by shifting emphasis away from the in idual and onto how practical, social and material arrangements around the oral health of preschool children exist, change or become embedded in the social structures they inhabit. This novel approach contributes to the growing theoretical understanding in this area and has the potential to offer insights into the problem and ways it might be addressed.

Perspectives of the public dental workforce on the dental management of people with special needs

Publisher: Wiley

Date: 19-03-2021

DOI: 10.1111/ADJ.12836

Abstract: People with special health care needs continue to have difficulties accessing regular dental care partly due to oral health professionals feeling they lack the knowledge and experience to provide treatment to these in iduals. Qualitative interviews and focus groups provided an insight into the types and nature of supports that oral health professionals working in the Australian public dental system desired and felt may improve their willingness and/or ability to treat patients with special needs. Although participants did not identify one group of patients with special needs that were more difficult to treat, they did report a feeling of being unsupported. Clinicians felt that improved training and access to ongoing education in Special Needs Dentistry, opportunities for greater support from specialists or other health professionals, either through networking or other media such as telehealth, and fostering a more supportive clinical environment, particularly in relation to appointment lengths and productivity pressures, may improve their willingness and ability to treat patients with special needs. Additional support, in the form of greater interaction with specialists and reduced time and productivity pressures, may improve the willingness of oral health professionals in the public dental system to treat patients with special needs.

Cost-effectiveness analysis of silver diamine fluoride to divert dental general anaesthesia compared to standard care.

Publisher: Wiley

Date: 29-09-2022

DOI: 10.1111/ADJ.12936

Abstract: The aim is to perform a model-based cost-effectiveness analysis of a silver diamine fluoride (SDF) protocol intervention to ert dental general anaesthesia (DGA) among Victorian children aged 2-10 years. Data inputs were based on an Australian single-cohort 2017/18 study. Intervention costs for standard care were derived from two subgroups of children: (1) children who received standard care without DGA, and (2) children who received standard care with DGA. Two scenarios were modelled due to limited post-follow-up data: (1) children receiving SDF had standard care without DGA (base-case scenario), and (2) children receiving SDF did not receive standard care without DGA (alternative scenario). A simple decision-tree model with probabilistic sensitivity analysis (PSA) estimated the incremental costs per erted DGA. The probability of children requiring specialist referral and offered SDF, but the primary carer opted for DGA is 0.124 (SD 0.034), and the probability of children requiring DGA in standard care is 0.346 (SD 0.036). For both the base-case and alternative scenario, the incremental cost-effectiveness ratio outcome is dominant and their cost-effectiveness being either 74.8% or 100% respectively. The SDF protocol intervention is cost-effective dental caries management option for young children where referral for DGA is considered. © 2022 Australian Dental Association.

Modeled health economic and equity impact on dental caries and health outcomes from a 20% sugar sweetened beverages tax in Australia

Publisher: Wiley

Date: 21-07-2023

DOI: 10.1002/HEC.4739

Abstract: Dental caries is the most prevalent oral disease across the life course. This study modeled the population health and economic impact of a 20% sugar sweetened beverages tax (SSB) for preventing dental caries compared to no intervention (societal and healthcare perspective). A cost‐effectiveness analysis according to quintiles of area‐level socioeconomic disadvantage was performed for the 2020 Australian population (0–100 years old) using a closed cohort Markov model. A qualitative assessment of implementation considerations (e.g., acceptability, equity, sustainability) was undertaken. Health outcomes were modeled as decayed teeth prevented and disability‐adjusted life years (DALYs) averted. The 10‐year and lifetime scenarios were modeled with probabilistic sensitivity analysis (Monte Carlo simulation, 2000 cycles). The 10‐year scenario from a societal perspective yielded cost‐savings of AUD$63.5M, healthcare cost‐savings of AUD$42.2M, 510,977 decayed teeth averted and 98.1 DALYs averted. The lifetime scenario resulted in societal cost savings of AUD$176.6M, healthcare cost‐savings of AUD$122.5M, 1,309,211 decayed teeth averted and 254.9 DALYs averted. Modeling indicated 71.5% and 74.5% cost‐effectiveness for the 10‐year and lifetime scenarios, respectively. A three‐fold health benefit for the least advantaged was found compared to the most advantaged. A 20% SSB tax in Australia is cost‐effective and promotes health equity.
