Introduction: Dental caries and molar–incisor hypomineralisation (MIH) are prevalent conditions affecting children’s oral health, with functional, aesthetic, and psychosocial implications. In Spain, previous studies have highlighted geographic and sociodemographic disparities in their distribution, particularly among rural and migrant populations. Objective: To characterise oral health status, in terms of caries and MIH, among 6–7-year-old children from the towns of Palos de la Frontera, Mazagón, and San Bartolomé. Methods: A cross-sectional study was conducted involving 229 children recruited from public primary schools. Sociodemographic, anthropometric, and behavioural data were collected through clinical examination and interview. Statistical analysis included univariate and multivariate logistic regression. The study protocol was approved by the Ethics Committee of Huelva. Results: The prevalence of caries (DMFT ≥ 1) was 53.3%, with mean DMFT and dft indices of 1.78 and 0.31, respectively. MIH affected 32.8% of the cohort, with a predominance in the first permanent molars (teeth 36 and 26). Multivariate analysis identified independent predictors of caries: African (OR = 7.47; 95% CI: 2.84–23.8) and European (OR = 4.56; 95% CI: 1.26–22.3) parental origin, poor oral hygiene (OR = 3.07; 95% CI: 1.60–6.03), and the presence of MIH (OR = 3.20; 95% CI: 1.64–6.42). The municipality of San Bartolomé was associated with a higher risk of MIH (OR = 2.90; 95% CI: 1.21–7.45). Conclusions: The high prevalence of caries and MIH in the Condado-Campiña district, exceeding national averages, reflects oral health inequities linked to social determinants (migrant origin, locality) and clinical factors (MIH, oral hygiene). Targeted preventive interventions are urgently needed in high-risk populations, including culturally tailored education and policies ensuring equitable access to dental care services. Full article

Periodontal disease is a common and serious oral disease among older adults. As the global older population increases, preventing periodontal disease is vital for healthy ageing. Poor oral hygiene, uncontrolled diabetes, and smoking are key risk factors of periodontal disease. Improving oral hygiene, diabetes management, and quitting smoking are essential health behavioural change interventions to manage periodontal disease. The objective of this study is to review the prevention of periodontal disease among older adults through health behavioural change interventions. Effective strategies to improve oral hygiene include personalised education on proper brushing and interdental cleaning. Educating caregivers is equally important as they supervise care-dependent older adults to maintain oral health. For those with diabetes, physical activity improves glycated haemoglobin levels and clinical periodontal parameters by reducing reactive oxygen species and systemic inflammation. Smoking cessation could be achieved through a multi-faceted approach. Effective smoking cessation combines brief interventions with intensive behavioural/pharmacological support for long-term success, especially in highly dependent individuals. Tailored strategies for older adults, integrated care, and expanded research improve outcomes and health equity in ageing populations. In conclusion, health behavioural change interventions are non-invasive preventive measures that include oral hygiene reinforcement, diabetic management, and smoking cessation. Prioritising these interventions empowers older adults to maintain oral health, reducing disease burden and enhancing overall well-being for healthy ageing. Full article

Sweet sensing is a fundamental sensory experience that plays a critical role not only in food preference, reward and dietary behaviour but also in glucose metabolism. Sweet taste receptors (STRs), composed of a heterodimer of taste receptor type 1 member 2 (T1R2) and member 3 (T1R3), are now recognised as being widely distributed throughout the body, including the gastrointestinal tract. Preclinical studies suggest these receptors are central to nutrient and glucose sensing, detecting energy availability and triggering metabolic and behavioural responses to maintain energy balance. Both internal and external factors tightly regulate their signalling pathways, and dysfunction within these systems may contribute to the development of metabolic disorders such as obesity and type 2 diabetes (T2D). Functional magnetic resonance imaging (fMRI) has provided valuable insights into the neural mechanisms underlying sweet sensing by mapping brain responses to both lingual/oral and gastrointestinal sweet stimuli. This review highlights key findings from fMRI studies and explores how these neural responses are modulated by metabolic state and individual characteristics such as body mass index, habitual intake and metabolic health. By integrating current evidence, this review advances our understanding of the complex interplay between sweet sensing, brain responses, and health and identifies key gaps and directions for future research in nutritional neuroscience.

Background/Objectives: The HPV vaccine is highly effective and safe in preventing HPV infection. This study explored the relationship between HPV vaccination, HPV knowledge and awareness, and oral HPV infection prevalence among Indigenous Australian adults. Methods: Data were collected from a large convenience sample in South Australia in 2018–19, with annual follow-ups through 2022–23. The primary outcome was oral infection with HPV types 6, 11, 16, 18, 31, 33, 45, 52, or 58. The main exposure was HPV vaccination uptake status, which was categorised as unvaccinated, partially vaccinated (1–2 doses), or fully vaccinated (3 doses). Covariates included sociodemographic factors, general and sexual health behaviours, and HPV knowledge scores (HPV-KT). Risk ratios (RRs) for oral HPV infection were estimated using Poisson regression models. Results: Among the 1006 participants who completed at least one questionnaire and oral HPV test by 24 months, 81% were unvaccinated, 13% partially vaccinated, and 7% fully vaccinated. Fully vaccinated individuals had the highest HPV-KT scores (mean: 3.4) and the lowest oral HPV prevalence (5%). After adjusting for covariates, unvaccinated participants had a 1.08 times higher risk of oral HPV infection (95% CI: 1.00–3.11) compared to those fully vaccinated. Conclusions: Full HPV vaccination (three doses) is associated with lower oral HPV infection and greater HPV knowledge. The protective effect appears stronger than for partial vaccination or no vaccination, underscoring the importance of completing the full vaccine series to reduce oral HPV burden. Full article

Background: The objective of this investigation was to assess the oral health (OH) of Bosnia and Herzegovinian adolescents in relation to differences and socioeconomic status (SES). Methods: This cross-sectional study included 306 school children from high schools located in the Tuzla Canton (Bosnia and Herzegovina). The sample consisted of 183 females and 123 males between 15 and 18 years old (mean of 16.82 years old). The study was conducted between December 2019 and March 2020, via an Annex 8 questionnaire from the World Health Organization (WHO), which collected information on OH behaviours, self-perceptions of oral health and dietary factors responsible for the OH of each subject. SES was categorized using five variables (occupation, education, income, place of residence and number of family members). Cross-tabulations were evaluated according to sex and socioeconomic status (SES) via the chi-square test. Results: Over 40% of the participants consumed sweets, cakes and biscuits on daily basis, whereas 41.5% of the participants visited a dentist only in the case of pain. The consumption of sweets (p = 0.024) and cakes and biscuits (p = 0.011) on a daily basis was significantly greater in female adolescents than in male adolescents. Compared with male adolescents, female adolescents reported occasional toothaches more frequently (p = 0.001) and were more dissatisfied with their dental appearance (p = 0.008) but presented a greater frequency of flossing (p = 0.001) and toothbrushing (3–5 times a day) (p = 0.0001). There was no association between the different levels (below average, average, above average) of SES and factors affecting OH status of adolescents. Conclusions: The study revealed significant sex differences in several factors affecting OH status and revealed no relationship between SES and OH behaviours or between perceptions and risk factors affecting OH in 15–18-year-old adolescents. Data obtained from this study might help in the creation of new OH prevention programs aimed at improving the OH status of adolescents in Bosnia and Herzegovina. Full article

With increasing numbers of dairy farms adopting zero-grazing systems, there is a growing need for indoor environmental enrichment methods. Enrichment is necessary to meet industry requirements and fulfil behavioural motivations, such as oral manipulation. This study evaluated the magnitude with which Holstein Freisen cows would interact with salt lick enrichment blocks based on the mounting design. Holstein Freisen dairy cows (n = 55) were recruited from a UK dairy farm and observed over a 4-week period (n = 20 days). Three different mounting designs were utilized, low non-moveable (LNM), low moveable (LM), and high moveable (HM), and the LNM setup was repeated on week 4. These mounting designs were each observed over a five-day period and then removed for two days in-between. Data were collected by in-person observation and included cow IDs, instances of interaction, and kilograms of salt lick used per setup. The data were analysed through IBM SPSS Statistics via a One-Way Repeated Measures ANOVA and Microsoft Excel to determine significant findings and habituation. The number of new interactions significantly decreased in the HM setup compared to the LM and LNM. The supporting data of kilograms of salt lick used and total percentage of the herd utilizing the blocks, also favoured the LM setups over LNM. The LNM setup was repeated on the final week to assess the level with which cows had habituated to the environmental enrichment. Despite a significant difference between week 1 and week 4, the trends of cow interactions showed individual variability in habituation and overall negligible herd-level habituation. These findings suggest that the use of mineral licks within a dairy herd serves as effective environmental enrichment, even over extended time periods, and when implemented they are best used at low heights with the ability to have free movement. When implemented on a farm, the LM mounting design should increase the herd-level uptake of enrichment leading to a reduction in stereotypies and fulfilment of oral motivation, which is beneficial for overall cow health and welfare.

Objectives: This study examines the mediating role of nutritional intake in the relationship between tooth loss and healthy ageing in older American adults. Methods: A secondary data analysis was conducted using the Health and Retirement Study (HRS), a longitudinal survey of American older adults aged 50 years and over. Data from six waves from 2006 to 2016 were used. Nutritional intake was assessed in 2013 using ten essential nutrients, categorised as adequate or inadequate based on national dietary recommendations. Healthy ageing was an aggregate variable composed of freedom from cognitive impairment, freedom from disability, and high physical functioning. Tooth loss was measured as a dichotomous variable (edentate/dentate). Structural equation modelling was used to assess the associations between tooth loss in 2012, nutrition in 2013, and healthy ageing in 2016, accounting for demographic/socioeconomic factors and behaviours. Results: A total of 3665 participants were included on the analysis. A significant association was found between being dentate in 2012 and nutritional intake in 2013 (coefficient 0.63: 95% CI: 0.62, 0.54, p < 0.001). Healthy ageing in 2016 was significantly influenced by socioeconomic factors in 2006 (coefficient 0.84: 95% CI: 1.38, 1.42, p < 0.001) and nutrition in 2013 (coefficient 0.05: 95% CI: 0.04, 0.05, p < 0.001). Non-Black individuals showed a significant association with healthy ageing. Conclusions: The findings underscore the complex interplay of nutrition, socioeconomic status, health behaviours, and oral health in predicting healthy ageing trajectories. This study highlights the importance of oral health to maintaining adequate nutritional intake, which in turn promotes healthy ageing. Full article

This study focuses on recreational horse owners in the UK and Ireland to explore the relationship between horse characteristics and welfare issues. An online questionnaire was distributed to 1501 horse owners to collect data on the owners, horses, and health/behavioural issues. Most respondents were female (98%), lived in England (56%), and did not insure their horses for veterinary costs (51%). Horses were typically over 5 years of age (96%), taller than 154 cm (55%), and mostly geldings (65%). Common welfare issues reported included lameness (26%), handling problems (11%), antisocial behaviours (9%), and abnormal oral behaviours (9%). Older horses were 4.23 times more likely to have lameness issues than younger horses (95% CI [2.17, 9.27], p < 0.001), while sport horse breeds were 3.12 times more likely to exhibit abnormal oral behaviours (95% CI [2.10, 4.73], p < 0.001) compared to other breed types. Whilst the study found a relatively low rate of welfare issues, the main problems reported were consistent with those seen in other studies. Age and breed appeared to influence the prevalence of these issues, although the relationships were weak. The study suggests that factors such as the owner’s attitudes, knowledge, and management practices may play a significant role in the incidence of welfare problems. Further research is needed to explore the impact of management on horse welfare. Full article

Background/Objectives: The rapid spread of antimicrobial resistance (AMR) presents a critical threat to global health. Primary care plays a significant role in this crisis, with oral antibacterial drugs among the most prescribed medications. Antibacterial prescribing rates are often high and complicated in out-of-hours (OOH) services, including weekdays outside regular hours, weekends, and holidays, potentially exacerbating AMR. This review aims to identify the existing literature on oral antibacterial drug prescribing within primary care OOH services. Methods: This review followed established frameworks, adhered to PRISMA-ScR guidelines, and the protocol was registered on Open Science Framework. Seven databases were searched from 2017 to May 2022. Data were summarised, tabulated, and presented narratively to explore themes and patterns that aligned with the review objectives. Results: The search identified 28 studies from nine high-income countries, mainly the UK (n = 6) and Belgium (n = 5). Most were quantitative studies (n = 23). Key areas identified included common oral antibacterial prescriptions, prescribing trends, presentations and conditions managed in OOH services, factors and predictors associated with prescribing, prescribing appropriateness, the impact of interventions on prescribing, prescribing in the context of COVID-19, patient satisfaction and expectations, and the challenges encountered, such as factors influencing prescribing behaviour and decision making, safety netting, and communication. Conclusions: This review highlights key areas around oral antibacterial prescribing in primary care OOH services. Despite the numerous articles identified covering various areas within OOH services, the variability in OOH services approaches across countries and studies complicates the comparison of practice. Further research is needed to better understand practices in these settings. Full article

Context: Diabetes rates are high in Black and some other ethnic communities, often leading to more severe complications. We conducted a study to identify the prevalence and risk of diabetes among African Caribbean Black (ACB) individuals aged 18–39 and to assess the sensitivity of glycated hemoglobin (HbA1c) compared to an oral glucose tolerance test (OGTT) to diagnose diabetes. Methods: In this mixed-methods study, maximum variation sampling was used to recruit 272 ACB participants from fourteen African and five Caribbean countries from Toronto. Participants’ height, weight, waist circumference, HbA1c, OGTT, demographic, and behavioural data were collected. SPSS was used to analyze the quantitative data. This study used descriptive statistics for frequency distribution and cross-tabulation while inferential statistics (regression, ANOVA, factor analysis, etc.) were used for relational analysis. Because of the small sample size, qualitative data were analyzed manually using the charting technique. Results: This study found that 1.5% of participants had diabetes, 9.2% had prediabetes, and 44.9% were at risk of developing diabetes. The mean value of HbA1c, FBS, and 2hPG was 5.5%, 4.8 mmol/L, and 5.7 mmol/L, respectively. The mean BMI was 28.2 kg/m², and the waist circumference was 85.8 cm. This study found a correlation between glucose intolerance and increasing body mass index (BMI) and waist circumference (WC). Dietary habits, physical inactivity, and mental health challenges were risk factors among the participants. HbA1c was found to be a more sensitive and culturally acceptable screening measure than OGTT in diagnosing diabetes. Conclusions: ACB individuals are at high risk of having diabetes, requiring culturally tailored peer-based health promotion strategies to reduce diabetes prevalence and risk. HbA1c is a culturally acceptable and statistically more capable measure than OGTT in identifying individuals with prediabetes. Further longitudinal research is needed. Full article

Background: The World Health Organisation (WHO) included silver diamine fluoride (SDF) in the WHO Model List of Essential Medicines for the management of early childhood caries. SDF is typically available as a 38% aqueous solution, which is watery to apply. A 38% SDF gel has recently been developed, but its caries-arrest effectiveness remains unsubstantiated. The objective of this study is to determine whether the efficacy of a 38% SDF gel is non-inferior to a 38% SDF solution in arresting early childhood caries. Methods: This is a 30-month, randomised, active-controlled, parallel-group non-inferiority pragmatic clinical trial with two arms. The hypothesis is that the 38% SDF gel is not worse than the 38% SDF solution by a non-inferiority margin of 10% caries-arrest rate when applied semi-annually to preschool children. This trial will recruit 630 3-year-old kindergarten children through block randomisation to receive either an application of SDF gel or SDF solution on cavitated carious lesions in their primary teeth every 6 months. The primary outcome is the proportion of soft (active) carious tooth surfaces that turn hard (arrested) at the 30-month follow-up. The same calibrated dentist will conduct 6-monthly dental examinations in the kindergartens to assess the status of carious lesions over 30 months. The examiner, the children, and parents will be blinded to treatments. The parents will be surveyed on their child’s oral health-related behaviours and socioeconomic background to allow adjustment for effect modification. Results: If the anticipated results are obtained, clinicians can use the 38% SDF gel as an alternative of the 38% SDF solution in arresting early childhood caries. Conclusions: As SDF gel is cost-effective, non-invasive, and non-aerosol-generating, it can be widely recommended for caries control. Trial registration: ClinicalTrials.gov NCT06241261.

Background: Age-related conditions, such as being misinformed, having limited oral health literacy, and the loss of manual dexterity, autonomy, or visual acuity, may act as barriers to oral health. The aim of this study was to evaluate the effectiveness of two different oral hygiene instruction methods on oral hygiene and the self-perception of oral health in older adults. Methods: This randomized controlled trial included participants aged 65 and older who completed a questionnaire on socio-economic factors, self-perceived oral health, and oral hygiene behaviours. Oral hygiene status was assessed using the Oral Hygiene Index—Simplified (OHI-S). Participants were randomly allocated into two different groups, according to the method of oral hygiene instruction: a “General Approach” (GA) (n = 28) and a “Personalized Technique” (PT) (n = 26). After two months, a follow-up session was conducted. Data were analysed using descriptive and inferential methodologies. Results: The GA and PT methods were effective in promoting oral hygiene behaviours, with a significant increase in the use of interdental devices, but no significant differences were found between the two methods. Self-perceived oral health did not change significantly, neither after the instruction nor between methods. Significant improvements were achieved with both methods for the OHI-S, with significant differences between the two methods for the Calculus Index, where the PT achieved better results. Conclusions: Oral hygiene education leads to improvements in the adoption of oral hygiene behaviours and clinical indicators. Furthermore, a personalized approach promoted better results in clinical indicators. Full article

Background/Objectives: The use of oral anticancer agents (OAA) dates to the late 20th century in cancer treatment. It is crucial that patients implement self-care behaviours to keep their disease stable and manage their OAA treatment. The three dimensions of self-care according to Riegel et al., self-care maintenance, self-care monitoring, and self-care management, may be implemented to avoid negative outcomes. This paper seeks to identify outcomes associated with self-care in breast cancer patients during treatment with OAA and to compare which of these outcomes fall into the core outcome categorizations in oncology (minimal set of outcomes that research on a given health issue should measure). Methods: A systematic review with narrative synthesis was conducted. This study included patients with breast cancer taking any kind of OAA and described outcomes of self-care. The search was performed on MEDLINE, Web of Science and CINAHL/PsycINFO; Results: Of 4173 records, eight studies were selected and reviewed. The core outcomes mainly considered were mortality, survival, disease recurrence and quality of life. All studies focused only on pharmacological adherence outcome; none of them focused on other dimensions of self-care. Conclusions: This systematic review highlighted that there is a great lack of research on outcomes related to self-care in patients with breast cancer taking OOA. Even though pharmacological adherence to OAA is important, other behaviours are also important to improve patients’ outcomes, but they have not been studied. Further research is needed to study how self-care behaviours can impact patients’ outcomes. Full article

Background and objectives: The role of parents and the family in promoting children’s oral health is increasingly acknowledged in the dental literature. This study aimed to investigate twelve-year changes in pre-schoolers’ oral health and parental involvement in children’s dental care using data from two repeated cross-sectional surveys. The objectives were (1) to assess the temporal changes in children’s dental health status and oral health-related behaviours, (2) to examine temporal changes in parental attitudes toward their children’s oral health care, and (3) to analyze the associations between observed changes. Materials and methods: Two identical cross-sectional surveys were conducted in 2010/2011 (n = 294) and 2023 (n = 304). In both surveys, parents answered questions regarding their children’s oral health care and completed the 38-item ‘Parental Attitudes toward Children’s Oral Health’ (PACOH) scale, while the dental health of their 3–7-year-old children was clinically assessed. Changes in the examined characteristics were analyzed using general linear models. Results: Significant positive changes (p < 0.001) were observed when comparing the surveys: the dmf-t (decayed, missing, filled teeth) score for deciduous teeth decreased from 5.56 to 3.31; the Silness–Löe Plaque Index decreased from 1.45 to 1.15; the percentage of children brushing their teeth regularly increased from 33.0% to 55.3%; the percentage of parents assisting their child with tooth brushing increased from 19.2% to 85.1%; and regular visits to a children’s dentist increased from 36.4% to 85.1%. Moreover, the study revealed better parental attitudes toward their children’s oral health care, as reflected by a change in the total score of the PACOH scale from 112 to 122. Conclusions: It was concluded that changes in parental attitudes played a crucial role in driving positive trends in oral health-related behaviours, which likely contributed to the improvement of dental health in children. Therefore, understanding and influencing parental attitudes can be essential for promoting good oral health skills and good oral health in young children. Full article

Background: The sexual transmissibility of enteric pathogens, including Salmonella spp., has been described in men who have sex with men (MSM). However, the factors seen in MSM with Salmonella spp. are poorly understood. Method: We aimed to systematically review the literature to explore any factors seen in MSM with Salmonella spp. (MSM). We searched six databases—Medline, PubMed, CINAHL, Embase, Emcare, and Global Health—in April 2024 for manuscripts which contained primary peer-reviewed data in English and the measurement of any risk factors observed in MSM with Salmonella spp. This review was registered on PROSPERO (CRD42023472864). Results: Eleven manuscripts were included in the final review and highlighted demographic (living with HIV), behavioural (oral–anal sex, receptive and penetrative anal sex, hand licking to stimulate their partner, group sex, non-condom use), and biological (co-infection with CMV, Mycobacterium avium complex, Strongyloides stercoralis, Blastocystis hominis, Klebsiella spp. Herpes simplex virus, Cytomegalovirus, Cryptosporidium, Histoplasmosis, Shigella spp.; previous infection with Treponema pallidum, Neisseria gonorhoeae, Chlamydia trachomatis and hepatitis B; and antimicrobial treatment failure) factors seen in MSM with Salmonella spp. Conclusion: Despite a limited number of manuscripts and individuals, this review highlighted some potential demographic, behavioural, and biological factors implicated in the transmission of Salmonella spp. in MSM. These data will provide insights for future guidelines, public health control strategies, and research. Full article
