OBJECTIVE: Dental caries in permanent teeth is one of the most common health issues-despite being preventable in early stages-due to inadequate regulation of preventive dental services in many countries. This study evaluates the association between regulation of preventive dental services and oral health outcomes. METHODS: This mixed-method study analysed data from 19 member countries of the Organisation for Economic Co-operation and Development (OECD). Oral health outcomes were measured using decayed missing and filled teeth (DMFT) indexes for children aged 12 to 18 years...

OBJECTIVE: The aim of this research was to investigate attitudes towards principles of professional ethics (PPE) amongst Iranian dentists working in Isfahan, Iran. METHODS: This pilot cross-sectional study was conducted amongst 273 dentists in Isfahan, Iran. A validated, comprehensive questionnaire including principles of respect for patient autonomy, nonmaleficence, beneficence, and justice was used to evaluate dentistry professional ethics aspects. Age, gender, marital status, type of graduate university, level of education, specialised field of study, work experience, workplace, and participation in ethics workshops and courses were registered from participants...

BACKGROUND: The Oral Health Observatory (OHO), launched in 2014 by FDI World Dental Federation, aims to provide a coordinated approach to international oral health data collection. A feasibility project involving 12 countries tested the implementation of the methodology and data collection tools and assessed data quality from 6 countries. METHODS: National dental associations (NDAs) recruited dentists following a standardised sampling method. Dentists and patients completed paired questionnaires (N = 7907) about patients' demographics, dental attendance, oral health-related behaviours, oral impacts, and clinical measures using a mobile app...

OBJECTIVES: The early or delayed surgical removal of an asymptomatic lower third molar (M3) in orthodontic patients remains controversial. This study aimed to determine the changes in the impacted level of M3 such as angulation, vertical position, and eruption space, after orthodontic treatment in 3 groups, namely non-extraction (NE), first premolar (P1) extraction, and second premolar (P2) extraction. METHODS: Relevant angles and distances related to 334 M3s from 180 orthodontic patients were assessed pre- and posttreatment...

INTRODUCTION: Rates of dental visits of older adults in the United States, particularly in Tennessee, are rapidly increasing, coupled with the growing complexity of older adults' dental treatment. Notably, increased dental visits help detect and treat dental disease and offer opportunities for preventive care. This longitudinal study aimed to examine the prevalence and determinants of dental care visits amongst Tennessee seniors. METHODS: This observational study combined multiple cross-sectional studies...

The aim of this review was to discuss traumatic dental injuries in view of their treatment implications to provide an evidence-based resource for clinicians when planning treatment for traumatised immature maxillary incisors. Dental trauma to immature maxillary incisors can result in various complications, such as critical fractures, resorptions, or ankylosis, and might lead to tooth loss. Traumatised teeth may exhibit various unaesthetic discolourations as a result of different dental trauma sequelae or materials used for treatment...

OBJECTIVES: This study aimed to synthesise a drug-delivery system based on a porous polymer hydrogel, with antimicrobial properties against Porphyromonas gingivalis and potential to be used in tissue regeneration. MATERIAL AND METHODS: 2-Hydroxyethyl methacrylate monomers were polymerised using thermal and photoactivation in the presence of silver nitrate (AgNO3 ) and/or chlorhexidine digluconate. Poly-2-hydroxyethyl methacrylate (pHEMA) hydrogels containing silver nanoparticles (AgNPs) and/or 0...

OBJECTIVES: Outcomes of oral health care must be measured and analysed to improve oral health care delivery, outcomes, and quality. This study aims to develop and test outcome measures for the needs of oral health organisers and explore their feasibility using clinical data. METHODS: Based on the literature review and oral health advisory board, outcome measures for oral health care were identified, developed, and tested. Data from 425,000 clinical examinations were obtained from the clinical records of 8 public oral care providers in Finland...

OBJECTIVE: This clinical trial aimed to compare the caries-preventive effect of annual application of 38% silver diamine fluoride solution (SDF) with 5% sodium fluoride varnish (FV) to the anterior primary teeth of children. The hypothesis was that SDF was superior to FV at 1 year. Secondary objectives were to determine the child's cooperation and the parent's satisfaction and assess adverse effects. METHOD: We recruited 688 3- to 4-year-old children and randomly allocated them to receive SDF or FV (positive control) on their 6 upper anterior teeth...

OBJECTIVES: Japan's universal health insurance covers a wide range of dental treatments, and the co-payment rates differ by age. We investigated whether the inequality in gingival bleeding and dental visits was smaller amongst those with lower co-payment rates. METHODS: This cross-sectional study used data from the 2019 Japan Gerontological Evaluation Study. The participants were functionally independent adults aged 65 years or older. The dependent variables were current gingival bleeding as a symptom of periodontal diseases and dental nonattendance for treatment in the past year...

OBJECTIVES: Oral cancer confers high morbidity and mortality rates. Late diagnosis of oral cancer is linked to a lack of awareness of its existence and known risk factors. The purpose of this survey was to examine the knowledge and awareness of oral cancer amongst different groups in Singapore. METHODS: A self-administered questionnaire (including questions on awareness, risk factor knowledge, and health beliefs about oral cancer) was distributed to undergraduate students from the medical and dental schools and other faculties at the National University of Singapore, as well as the general public...

OBJECTIVE: The purposes of this study were to analyse trends in primary tooth emergence patterns and to identify physical factors potentially associated with them. METHODS: The participants were 27,454 infants who underwent routine 18-month-old health examinations in Ebetsu City, Japan, between 1980 and 2012. This study was conducted using data from infants' 18-month-old health examinations over a 33-year period. The mean number of emerged primary teeth was analysed by sex using a general linear model...

INTRODUCTION: The aim of this study was to assess the dynamic cyclic fatigue resistance of an R-Motion file at simulated body temperature and document corresponding phase transformations compared to OneCurve and HyFlex EDM (HFEDM). METHODS: R-Motion (25/.06), OneCurve (25/.06), and HFEDM (25/.06) files were selected and divided into 3 groups (n = 9) according to the file type. Dynamic cyclic fatigue testing was done with a custom-made artificial stainless-steel canal that had a 90° angle of curvature and a 5-mm radius of curvature...

OBJECTIVE: The learning environment plays a vital role in dental education. A positive learning environment could improve students' satisfaction, psychosocial well-being, and academic achievement. This study set out to measure the quality of the learning environment according to the Dundee Ready Educational Environment Measure (DREEM) at different dental schools in Syria. METHODS: The study included dental schools at Damascus University (DU), Tishreen University (TU), and University of Hama (HU)...

The term bioactivity is being increasingly used in medicine and dentistry. Due to its positive connotation, it is frequently utilised for advertising dental restorative materials. However, there is confusion about what the term means, and concerns have been raised about its potential overuse. Therefore, FDI decided to publish a Policy Statement about the bioactivity of dental restorative materials to clarify the term and provide some caveats for its use in advertising. Background information for this Policy Statement was taken from the current literature, mainly from the PubMed database and the internet...
