A quantitative and qualitative investigation into the management of carious primary molars by foundation dentists in primary care in the South East of England.

Introduction Dental caries is the most common reason for hospital admission of children aged 5-9 in the UK. Better management of caries in primary molars would reduce the number of children requiring treatment in hospitals; however, little research has been done into why primary care clinicians do not use an evidence-based approach to caries management for deciduous molars.Aims The aim of this paper is to identify the rationale behind caries management techniques used in primary care, as well as the choice of materials and long-term success of restorations placed.Materials and methods Use of a retrospective audit and a focus group with primary care clinicians to provide an insight into the management of carious primary molars and the barriers to achieving gold standard care.Results Glass ionomer cements (GICs) were the restoration of choice in primary care. Lack of time, equipment availability and clinician inexperience were cited as to why Hall crowns were not commonly placed.Conclusions The barriers to gold standard management of carious primary molars in practice are wide-ranging but tend to focus on the limitations of NHS care under the units of dental activity system. Lack of time and cost of materials encouraged clinicians to adopt a 'quick fix' approach in GIC.

A discussion of current scientific evidence base pertinent to primary care dentistry highlighting the need for ‘effectiveness’ rather than ‘efficacy’ studies is included in order to provide research data pertinent to the primary care dentistry setting where most dental patients receive most of their care most of the time.

Rising incidence of severe maxillofacial space infections in Germany

ObjectivesSevere maxillofacial space infection (MSI) as an end stage of dentoalveolar diseases or complication of sialadenitis is a potentially life-threatening disease accompanied by complications including airway obstruction, jugular vein thrombosis, descending mediastinitis, sepsis and acute respiratory distress syndrome. The aim of this study was to analyze the incidence and time trends of severe MSI and potentially influencing factors in the German healthcare system over time.Materials and methodsNationwide data regarding the national diagnosis-related-group (DRG) inpatient billing system was received from the German Federal Statistical Office. A retrospective analysis of incidence and time trends of MSI-associated procedures classified with the Operation and Procedure Classification System (OPS), were statistically evaluated using Poisson regression analysis between 2005 and 2022 and were associated with different epidemiological factors.ResultsThe total standardized incidence rate of MSI-associated procedures in the observational period 2005—2022 was 9.8 (♀8.2; ♂11.4) per 100,000 person years. For all age groups a significant increase of 46.1% in severe MSI – related surgical interventions was registered within the observational period. The largest increase (120.5%) was found in elderly patients over 80 years. There were significant differences of the incidences of MSI-associated surgeries between the different federal states in Germany.ConclusionsSevere MSI are a growing challenge in German health care especially among elderly patients over 80 years.Clinical relevanceSevere MSI is a promising target for prevention. There should be more focus in primary dental and medical care especially in groups depending on social support.

COVID-19 case management in primary dental care settings in Yorkshire and the Humber.

Introduction Emerging guidance during the COVID-19 pandemic aimed to minimise transmission risk within dental settings. This service evaluation provides an overview of reported cases of COVID-19 among primary dental care staff within Yorkshire and the Humber.Methods Data for COVID-19 cases reported within dental practices between November 2020 and August 2021 were extracted from the Public Health England, Health Protection Zone database and summarised using descriptive statistics.Results In total, 421 cases across 223 dental practices were reported, with 221 close contacts and 77 outbreaks identified. Cases/contacts were highest among dental nurses (51/49%). Household and community (42/22%) were the most frequently reported sources of transmission, with the majority of staff-to-staff contacts (60%) occurring in communal/non-clinical areas.Discussion There was a low number of reported COVID-19 cases/contacts among dental professionals, with most cases suspected to have acquired the infection from outside of the dental setting. The majority of personal protective equipment breaches occurred within communal/non-clinical areas. When infection prevention and control guidance was followed, there were no incidences of staff or patients becoming contacts or cases.Conclusion With adherence to strict protocols, the risk of COVID-19 transmission in the dental setting was low within the context of this review. The evaluation highlighted the importance of collaborative working during the pandemic.

Primary care dentistry: An Australian perspective

IntroductionPrimary care dentistry is the first point of contact that someone has with the dental system and is predominantly focused on the treatment and prevention of dental caries and periodontal disease. The aim of this paper was to review the Australian primary dental care system. MethodsThis paper reviews the primary dental care system in Australia, drawing on data reporting on the dental workforce, funding sources for dental care, oral health outcome measures and dental visiting patterns. ResultsPrimary dental health care in Australia is predominantly provided by dentists working in private practice, with the number of dentists per 100,000 people in Australia increasing from 46.9 in 2000 to 65.1 in 2022. However, there has been a gradual shift over the past twenty years towards greater service provision by other members of the dental team who now represent one quarter of the dental workforce, and some expansion of publicly funded dental care. Despite this dentistry remains isolated from the rest of primary health care, and the lack of government funding means that many people continue to miss out of necessary dental care, particularly those living in regional and rural Australia and from low-income groups. ConclusionsAustralians should be able to access primary dental care services when and where they need it with adequate financial protection, from services that are well integrated into the broader primary health care system to ensure they are able to achieve optimal oral and general health. For many Australians, this is not currently the case. Clinical significanceAustralia is at a crossroads with respect to access to dental care, and there is a need for stronger advocacy from stakeholders to improve oral health outcomes and reduce inequalities.

Awareness and Incorporation of the Dental Home Concept Among General Dentists and Dental Therapists in Malaysia.

Background The dental home concept (DHC) refers to an approach in oral healthcare that emphasizes establishing a long-term, comprehensive, and family-centered relationship between a patient and their primary dental care. This study determined the awareness and incorporation of the DHC among general dentists and dental therapists in Malaysia. Methodology A total of 154 general dentists and 137 dental therapists providing oral healthcare services at the Ministry of Health (MOH) primary care facilities throughout Malaysia participated in this cross-sectional study. A self-administered questionnaire was used to measure the respondents' awareness of the DHC and incorporation of the DHC characteristics into their practice. Results Most dentists and dental therapists (61.7% and 67.2%, respectively) had not heard of the term DHC and were unaware of the concept. The respondents' awareness was not associated with their age, sex, years of service, facility location, and percentage of treatment given to children aged five years and below. However, most dentists and dental therapists responded positively about incorporating most DHC characteristics into their current practice. Conclusions Most dentists and dental therapists serving the MOH primary oral healthcare facilities were unaware of the DHC, although most DHC characteristics have already been incorporated into their practice. This study provides evidence of the incorporation of the DHC into the MOH primary oral healthcare services and suggests an effort to increase the awareness of the workforce regarding the concept and its implementation.

Current arrangements for training dentists in Australia on primary care dentistry

There is an expectation in Australia that dental students engage in primary care as they learn to recognise and respond to aspects of a person's general health and wellbeing. These skills, knowledge and behaviours are outlined by the Australian Dental Council, the accrediting body of dental training programs. Education in primary care dentistry can be seen integrated across the length and breadth of dental curricula yet is not commonly referred to as primary care. Interprofessional education provides opportunities for dental students to develop their professional identities as primary healthcare practitioners and be seen as such by other health professions. We propose that the primary care dentistry could be elevated by naming and noticing these activities in the curriculum.

Challenges in conducting clinical research in primary care dentistry

The integration of dentistry into primary health care is crucial for promoting patient well-being. However, clinical studies in dentistry face challenges, including issues with study design, transparency, and relevance to primary care. Clinical trials in dentistry often focus on specific issues with strict eligibility criteria, limiting the generalizability of findings. Randomized clinical trials (RCTs) face challenges in reflecting real-world conditions and using clinically relevant outcomes. The need for more pragmatic approaches and the inclusion of clinically relevant outcomes (CROs) is discussed, such as tooth loss or implant success. Solutions proposed include well-controlled observational studies, optimized data collection tools, and the integration of artificial intelligence (AI) for predictive modelling, computer-aided diagnostics and automated diagnosis. In this position paper advocates for more efficient trials with a focus on patient-centred outcomes, as well as the adoption of pragmatic study designs reflecting real-world conditions. Collaborative research networks, increased funding, enhanced data retrieval, and open science practices are also recommended. Technology, including intraoral scanners and AI, is highlighted for improving efficiency in dental research. AI is seen as a key tool for participant recruitment, predictive modelling, and outcome evaluation. However, ethical considerations and ongoing validation are emphasized to ensure the reliability and trustworthiness of AI-driven solutions in dental research. In conclusion, the efficient conduct of clinical research in primary care dentistry requires a comprehensive approach, including changes in study design, data collection, and analytical methods. The integration of AI is seen as pivotal in achieving these objectives in a meaningful and efficient way.

Precision Prosthodontic Rehabilitation of Flabby Ridge with a Modified Window Technique: Case Report

Flabby ridge, also known as a soft (mobile), movable, or displaceable ridge, presents a common clinical challenge in dental practice. It primarily affects the alveolar ridges of the upper (maxillary) or lower (mandibular) arches. The anterior region of the maxilla is especially susceptible in edentulous patients. The flabby ridge lacks the firmness and stability required, leading dentures to become loose and unstable. Consequently, this instability can result in discomfort, speech and eating difficulties, and reduced quality of life for denture wearers. The flabby ridge often does not provide the necessary contour and resilience needed to establish an effective seal and maintain suction between the denture base and the underlying tissues. This compromises denture retention, making them susceptible to dislodgement during typical oral functions. Therefore, rehabilitating a completely edentulous patient with flabby tissue presents a formidable challenge for prosthodontists, as it undermines the retention, stability and support of complete dentures. Methods for managing flabby ridges encompass surgical removal, ridge augmentation, specialized impression techniques, balanced distribution of occlusal loads and implant therapy. Various impression techniques have been proposed to address the complexities of such cases. By carefully applying the principles of complete denture construction, a palliative treatment approach can be achieved. Special impressions often employ the window technique to capture a static impression of the flabby area, which introduces its own set of challenges. This innovative case report introduces a modified window technique that incorporates precise record transfer of the flabby ridge using tissue (blotting) paper. Specifically designed for the anterior mandibular flabby ridge, the technique employs a custom tray with a window positioned over the flabby tissues. A mucostatic impression material is utilized to minimize pressure on the flabby tissue, thereby reducing potential tissue distortion during the impression process. The procedure is executed in two steps: first, stable structures are recorded, followed by capturing the mobile tissues using light-body polyvinyl siloxane (PVS) elastomeric impression material within the window area. This method ensures an accurate record of the denture-supporting structures while maintaining the contour and details of the flabby tissues without displacement. Importantly, the technique is crafted for straightforward implementation by general dental practitioners within a primary dental care setting.

Current arrangements for training dentists in the UK in primary care dentistry

Primary Care Dentistry is the destination for the majority of UK dental graduates for some if not all of their future careers. Traditionally Undergraduate Dental Education has been set and delivered within the Secondary Care (specialist referral and Dental Hospital) environment, which may create challenges for new graduates when preparing them for their careers. This article discusses undergraduate dental training for and within Primary Care Dentistry.

Brazilian primary dental care in a universal health system: Challenges for training and practice

ObjectivesTo report the challenges for training and practice for the Brazilian primary dental care in a universal health system. MethodsHealth, education and protection rights against poverty are guaranteed by the 1988 Brazilian Constitution and public health in Brazil is provided by the Unified Health System (SUS), one of the largest public health systems in the world. According to SUS, every Brazilian citizen has the right to free primary oral health care as secondary and tertiary care, offering a unique opportunity to integrate oral care within general health care. ResultsThe Brazilian undergraduate Dental curriculum was updated in 2021 aiming to graduate general practitioners with a major in comprehensive health care in primary health care, integrated with public and general health. This curriculum update requires at least 20% of the academic hours to be exercised outside the university walls (extramural or community work), preferably within the SUS. ConclusionsConsidering the World Health Organization (WHO) agenda, Brazil needs to advance the innovative oral health workforce, the integration of oral health into primary care, the population access to essential dental medicines and optimal fluorides for caries control. Clinical significanceIt is necessary political action and the engagement of multiple stakeholders, mainly from the health and education sectors, to improve primary health care

Modelling the Future Malaysian Clinician Dental Workforce using System Dynamics

Introduction: The aim of this operational research workforce project was to build, and test, a clinical dental workforce model for Malaysia to address population need/demand with a view to informing health policy. Methods: A system dynamics (SD) model was developed to take account of population oral health needs and demands and dental workforce supply nationally from 2010 to 2040. This involved building two sub-models: population need/demand; and dental workforce supply, drawing on evidence from two previous studies (student survey and interviews of key-stakeholders) supported by government data. The two sub-models were integrated in relation to clinical time to explore potential of over- or under-supply of clinical hours; were latter converted to clinical workforce numbers. The SD model was tested and validated as an acceptable baseline model for Malaysia using existing workforce data. Results: A SD model was developed to model the need, supply and demand for dental care in two sectors from 2010 to 2040. There is a short-term need for an expanded dental workforce to meet the needs of the population but there is a potential oversupply of dentists and therapists from 2040, or earlier. The level of public demand for both primary and secondary dental care is expected to increase respectively from the year 2010 to 2040, varying in relation to demographic and health trends across public and private sectors. Conclusion: The study suggests there is are current requirements for an expanded dental workforce to serve the population needs/demand and potential for oversupply from 2040, or earlier.

Preparing students for primary dental care in the Republic of Ireland

There are two dental schools in the Republic of Ireland, graduating approximately 90 new dentists annually following successful completion of a five-year undergraduate course. Currently, once these graduates have been awarded their degree, they have no legal requirement to complete post-graduation training, foundation training or continuing professional development. While the vast majority will do this voluntarily, it sets a high bar for dental educators to prepare these students to practice independently in primary dental care. As in other jurisdictions, there can often be a disconnect between the ethos taught to students for delivering primary dental care in dental schools and remuneration systems once graduates enter the workforce. Changing demographics will need to be reflected in our undergraduate curricula with explicit teaching in the area of gerodontology.

Perception of Behaviour Management Techniques for Paediatric Patients among Dental Officers

Introduction: Dental anxiety can be effectively managed by applying pharmacological and non-pharmacological behavioural management therapy approaches (BMT). This study investigated the dental officers’ perception of behaviour management techniques practiced in managing paediatric dental patients in primary dental clinics. Materials and methods: A quantitative study using structured online English questionnaires among dental officers serving in primary dental care services under the Ministry of Health Malaysia (MOH Malaysia) in Sabah. The acceptability of applied behaviour management techniques was measured using Likert scale from 0 to 10. Data was analysed using SPSS version 29 and descriptive data was presented. Results: Seventy-four dental officers involved in this study (Male= 14, Female= 60). Positive verbal reinforcement, tell-show-do, and offering an exact explanation of what the findings indicate are the most widely accepted behaviour management strategies (BMT), with mean scores of 9.5, 9.1, and 8.7, respectively. The least accepted BMT among dental officers in Sabah are immobilisation with a papoose board, preventing the child from speaking during treatment, and hand over mouth (HOM), with mean scores of 4.6, 3.6, and 3.2, respectively. Conclusion: The study concludes that the most recognized BMT is positive reinforcement technique regardless of age, experience and gender. This finding provides information in the development of modules for continuous professional development training among dental officers in the Ministry of Health Malaysia.

Five parapremolars in a non-syndromic patient: A case report

Supernumerary teeth or hyperdontia are additional or an excessive number of teeth present in normal deciduous or permanent dentition. The prevalence of supernumerary teeth is between 0.1 and 3.8% in permanent dentition and between 0.3 and 0.8% in deciduous dentition. In Sabah, the prevalence of supernumerary teeth is 10.32% among orthodontic patients. The condition is more common in male patients. A case report involved a fit and healthy 19-year-old male student who presented with multiple supernumeraries. Upon clinical examination, there were three erupted supernumeraries on the bilateral mandibular premolar region, and additional two impacted supernumeraries being discovered after further radiographic investigation. This anomaly was found during an annual dental school checkup program. The patient had congenital absence of the lower left third molar. Primary dental care was carried out such as filling for carious teeth, scaling, oral hygiene reinforcement and regular monitoring. The patient declined any other dental treatment options such as extraction of the non-functioning supernumerary parapremolar teeth, or orthodontic treatment to improve his malocclusion. Currently, the patient is under oral hygiene maintenance with regular dental follow-ups. In a nutshell, the importance of regular dental follow-ups and review is crucial to monitor any signs and symptoms of pathology such as cystic formation of unerupted supernumeraries. Reinforcement of oral hygiene and caries risk assessment should be carried out during reviews to improve and maintain the patient’s quality of life.

Impact of COVID-19 pandemic on pediatric dental procedures in primary healthcare settings in Piracicaba, Brazil: an ecological study

BackgroundThe COVID-19 pandemic brought significant changes to dental care, which may have affected pediatric dental care offered in primary healthcare settings. Therefore, the aim of this study was to analyze the quantity of dental procedures performed in primary healthcare for children aged 6 to 12 years, before and during the COVID-19 pandemic.MethodsThis is an ecological study using data from the health information system of Piracicaba, São Paulo, Brazil. The variables considered were: coverage of first programmed dental consultation, restoration of permanent and deciduous teeth, topical fluoride application (individual per session), emergency care, and deciduous tooth extraction. Two periods were considered: period I (March 1, 2019 to February 29, 2020) and period II (April 1, 2020 to March 31, 2021), before and during the pandemic, respectively. Comparisons between periods were made using the paired nonparametric Wilcoxon test with a significance level of 5%.ResultsThere was an increase in emergency care from 15.4 to 32.4% (p = 0.0095) and a decrease in the number of restorations of deciduous teeth from 32.8 to 20.2% (p = 0.0217). The first programmed consultation showed a decrease of 9.60% (p = 0.0930) in period II.ConclusionsThe COVID-19 pandemic has hindered access to primary dental care for children, impacting the quantity of emergency care, reducing restorations of deciduous teeth, and first programmed dental consultations. These findings highlight the need for strategies to ensure that pediatric dental care is not neglected during pandemics.

Student and clinical supervisor perceptions of community-based dental educational experiences: A scoping review.

This scoping review was conducted to map the breadth of experiences in community-based dental education (CBDE), as reported by students and clinical supervisors. This scoping review was conducted following the structured framework proposed by Arksey and O'Malley and adhering to PRISMA-SCR guidelines for scoping reviews. Applying specified eligibility criteria, a systematic search of four electronic databases (PubMed, Scopus, Embase, and Web of Science) was followed by data extraction and data synthesis of full-text articles. Research was conducted between June 2022 and September 2022. Sixteen articles were identified for the final full-text review. Utilizing a narrative thematic review, the following five domains emerged: preparation for autonomous practice, understanding of primary care dentistry, understanding of health disparities and patient needs, clinical confidence, clinical diversity, and skill development, and perspectives on quality of teaching and assessment. Community/outreach dental education effectively supplements traditional dental school-based education from the perspectives of students and community-based clinical supervisors.

Barriers to Accessing Primary Dental Care in Adults with Alcohol Dependence: A Qualitative Study.

People with alcohol dependence (AD) frequently experience oral health problems, but their dental attendance is poor, with limited evidence to the reasons why from their perspective. To explore perceived barriers, motivators, and facilitators to accessing primary dental care in people with AD. Qualitative study consisting of remote one-to-one and group semistructured interviews with a convenience sample of adults with lived experience of AD in northern England. Data were audio-recorded, transcribed, and coded. A reflexive thematic analysis method was used; use of COM-B model informed data interpretation. Twenty adults with lived experience of AD participated in 18 one-to-one interviews and 1 group interview (of 3 participants). Barriers to access were fear and physical, social, and environmental factors (physical effects of AD, financial barriers, nonprioritization of oral health). Motivators to access were pain and prioritization of oral health. Facilitators to access were patterns of alcohol use (i.e., sobriety) and dental service provision within recovery services. Fear of "the dentist" is a major barrier to accessing dental care, and pain is the primary motivator, among people with AD, although neither are unique to this population. Fear and physical, social, and environmental barriers to access contribute to problem-oriented attendance, which negatively affect oral health outcomes. Opportunity to facilitate attendance increases when a person is in remission from AD through their physical capabilities improving. Increasing capability and opportunity can influence attendance beyond the automatic motivation of pain. Provision of dental care within recovery services could facilitate access to care. Understanding the "web of causation" is key to developing any intervention to improve dental access in people with AD. Further research is needed from the perspective of other adult populations with lived experience of AD, as well as of dental professionals, to gain deeper insight into barriers, facilitators, and possible solutions. The results of this study can help dental professionals understand factors affecting access to primary care in people with alcohol dependence to provide knowledge that may reduce stigma surrounding the disease. Results also demonstrate areas for intervention development for public policy.

Unmet Dental Needs in Children Following Suspension of School-Based Oral Health Services Due to COVID-19.

Dental caries (tooth decay) is the world's most prevalent noncommunicable disease and can lead to pain, infection, and edentulism. Many children with caries lack access to traditional dental services. School-based caries prevention can increase access to care and reduce health inequities. Disruptions in school-based care due to pandemic control policies may result in children losing access to their primary dental care option. The CariedAway project was a school-based caries prevention program in operation from 2019 to 2023 in urban schools with a high proportion of low-income, minority students. Program operations were suspended for 2 years due to the COVID-19 pandemic. We estimated the prevalence of untreated decay, swelling, fistula, and pulpal involvement in participants at baseline and again after restrictions were lifted. A total of 2998 children between the ages of 5 and 13 years were enrolled and received preventive care prior to pandemic shutdowns, and 1398 (47%) completed a follow-up observation after 2 years. At baseline, approximately 30% had untreated caries on any dentition, 11% of children presented with evidence of dental sealants, and no participants had swelling, fistula, or pulpal involvement. After 24 months, 12% of participants had swelling fistula, or pulpal involvement that was not treated during the pandemic period. There are considerable unmet dental needs in high-risk children that may be further exacerbated by a lack of access to care during disease outbreaks.

The use of medicaments in the management of symptomatic irreversible pulpitis: A community-based cohort study.

To investigate patient outcomes from either pulpotomy or pulpectomy for the management of symptomatic irreversible pulpitis, with and without application of antibiotic/corticosteroid pastes in urgent primary dental care settings in the United Kingdom. All patients receiving intervention for symptomatic irreversible pulpitis in three different primary care settings were invited to participate. Pre-operatively, data regarding patients' numerical ratings scale (NRS), pain score (0-10), analgesic use, oral-health impact profile-14 (OHIP-14) and need for time away from work were collected. For 7 days post-operatively, participants recorded their NRS pain score, global rating of change score, medication use and their ability to work. Analysis used a mixed-effects model with post hoc Tukey's multiple comparisons test for continuous data and chi-squared or Fisher's exact test for categorical data. To test the effect of the corticosteroid/antibiotic paste, pulpectomy and pulpotomy groups were combined following Mantel-Haenszel stratified analysis or a weighted average of the difference between pulpotomy and pulpectomy with and without the use of corticosteroid/antibiotic paste. A binary composite score was constructed using pre- and post-operative data, whereby overall treatment success was defined as: (i) patients did not return for treatment due to pain by day seven; (ii) at day three, there was a 33% (or 2-points) reduction in NRS pain score; (iii) there was a change score of +3 in global rating; (iv) the patient was no longer using analgesia and able to return to work. Eighty-five participants were recruited, with 83 completing follow up. Overall treatment success was 57%, with 25% of participants returning for more treatment due to inadequate pain relief. Overall treatment success did not differ between the two groups (p = .645), although patients self-reported greater improvement with an antibiotic/corticosteroid dressing for global rating of change (p = .015). This study identified limited evidence of improved outcomes using antibiotic/corticosteroid dressings in the management of symptomatic irreversible pulpitis in the emergency setting. Further clinical research is needed to understand if these medications are beneficial in affording pain relief, above that of simple excision of irreversibly inflamed pulp tissue.
