ABSTRACT
BACKGROUND: Oral health impacts systemic health, individual well-being, and quality of life. It is important to identify conditions that may exacerbate oral disease to aid public health and policy development and promote targeted patient treatment strategies. Developmental defects can increase an individual's risk of dental caries, hypersensitivity, premature tooth wear, erosion, and poor aesthetics. As part of an ongoing study assessing oral health in adults with cystic fibrosis at Cork University Dental School and Hospital, a systematic review of available literature was conducted to assess the prevalence of enamel defects in people with cystic fibrosis. AIMS: To critically evaluate the literature to determine if the prevalence of developmental defects of enamel is higher in people with cystic fibrosis (PwCF). METHODS: Data Sources: Three online databases were searched Embase, Scopus, and Web of Science Core Collection. Studies that examined an association between cystic fibrosis and developmental defects of enamel were included in this systematic review. RESULTS: The initial search identified 116 publications from the following databases Embase, Web of Science Core Collection, and Scopus. Eleven studies were included for qualitative analysis. Nine studies concluded that PwCF had a higher prevalence of enamel defects than control people and one study found no difference in cystic fibrosis (CF) status. All studies had a risk of bias that may influence study results and their interpretation. CONCLUSIONS: The results of the systematic review show a consistent pattern that PwCF have a higher prevalence of DDE than people without CF. Genetic dysfunction, chronic systemic infections, and long-term antibiotic use are possible aetiological causes. This review highlights the need for future studies to investigate if DDEs are caused by the underlying CFTR mutation or as a consequence of disease manifestations and/or management.

We describe the development and student evaluation of a collaborative health service provider and higher education institution initiative designed to deliver an Interprofessional Education (IPE) pilot workshop program for healthcare students. The aim was to investigate whether an IPE workshop would result in improved student confidence in self-reported interprofessional competencies using the Interprofessional Collaborative Competency Attainment Scale (ICCAS) tool. The workshops involved interprofessional student groups working on a patient case followed by a facilitator-led discussion and patient representative interaction. There were three different voluntary, extra-curricular workshops. A total of 99 students registered, from 3rd to 5th year undergraduate and 2nd year graduate entry healthcare programs at a single Irish university in February 2022. Ninety-three post-workshop survey responses showed statistically significant improvements in the ICCAS subscales of Communication, Collaboration, Roles and Responsibilities, Collaborative Patient/Family-Centered Approach, and Team Functioning; Conflict Management showed less change. Students reported positively on the benefit of the patient representative, the workshop format, and the opportunity to collaborate with students from other professions. Our findings indicate that this was a beneficial and effective way to deliver IPE across a range of healthcare professions that led to improvements in self-reported interprofessional competencies.

BACKGROUND: Calls are emerging for oral health system reform under the Universal Healthcare (UHC) domain, while internationally there is an absence of political priority for oral health. In the Republic of Ireland there is very limited coverage of oral healthcare for the whole population. 'Smile agus Sláinte' Ireland's oral health policy published in 2019, represents the first change to national policy in over 25 years. METHODS: This research examined the key factors influencing oral health policy, development, and implementation in Ireland during the period 1994-2021. A case study approach was adopted with two strands of data collection: documentary analysis and semi-structured interviews with elite participants. Analysis was guided by Howlett's five stream framework. RESULTS: Ireland shares the international experience of oral health having very low political priority. This has perpetuated unequal access to public dental services for children and special needs populations while austerity measures applied to adult schemes resulted in increased unmet need with no universal coverage for dental care. The only area where there is political interest in oral health is orthodontic care. This low political priority combined with a lack of actor power in national leadership positions in the Department of Health and Health Service Executive has contributed to successive non-implementation of oral health policy recommendations. This is most evident in the failure to publish the Draft National Oral Health Policy in 2009. The research finds a failure to adequately engage with key stakeholders, particularly the dental profession in the development of the 2019 policy. All these weaknesses have been exacerbated by the COVID-19 pandemic. CONCLUSIONS: Ireland's new oral health policy, 'Smile agus Sláinte', presents an opportunity for the provision of much needed public dental services. However, successful reform will require strong political will and collaboration with dental leadership to provide advocacy at national level. Global calls to incorporate oral health into the UHC agenda and an agreed political consensus for UHC in Ireland may provide an opportunity for change. Genuine engagement of all stakeholders to develop an implementation strategy is necessary to harness this potential window of opportunity for oral health system reform.

OBJECTIVES: (i) To develop, validate, and apply in practice a new risk assessment tool for erosive tooth wear (ETW) including a risk factors questionnaire and a saliva secretion evaluation, which combined with a clinical index, can be part of an ETW composite scoring system; (ii) to assess ETW lesions and current and past erosive challenges in younger age groups. METHODS: The Tooth Surface Loss/Erosion Working Group of the European Association of Dental Public Health consisted of an international panel of experts designed the survey component of the new tool (Erosive Wear Assessment of Risk-EWAR) and confirmed its construct and content validity. After receiving ethical approvals and informed consents, the EWAR tool (questionnaire + saliva secretion evaluation) was applied in a multicenter cross-sectional study with 207 participants aged 15-21 years old from four countries (Finland, Greece, Romania, the USA). BEWE score was used for the clinical assessment of ETW. RESULTS: A total of 58.5% of participants had ETW. 10.9% and 20.3% of participants had low secretion of stimulated (< 1 ml/min) and unstimulated saliva (< 0.25 ml/min), respectively. The following factors were bivariately significantly associated with ETW: energy drink consumption, low secretion of stimulated saliva, juices consumption, erosive drink consumption for quenching thirst between meals, erosive drink kept in the mouth, feeling pain/icing after consuming something acidic or cold, and co-existence of other type of tooth wear. In regression analysis, only energy drink consumption (OR = 3.5, 95% CI: 1.39, 8.9), low secretion of stimulated saliva (OR = 36.3, 95% CI: 4.71, 78.94), and feeling pain/icing (OR = 8.8, 95% CI: 1.92, 40.04) remained significant. CONCLUSIONS: The examiners of the study reported that the EWAR tool appeared to be an affordable and easy-to-use instrument. Some challenges occurred during the saliva collection process. Inferential analysis revealed that the risk factors/indicators of low stimulated salivary flow, energy drink consumption, and pain/icing with ETW were considered the most important in ETW occurrence. CLINICAL RELEVANCE: EWAR tool combined with the BEWE clinical index can be used for ETW risk assessment for epidemiological studies and chairside use.

BACKGROUND: Community water fluoridation (CWF), the controlled addition of fluoride to the water supply for the prevention of dental caries (tooth decay), is considered a safe and effective public health intervention. The Republic of Ireland (Ireland) is the only country in Europe with a legislative mandate for the fluoridation of the public water supply, a key component of its oral health policy. However, more recently, there has been an increase in public concern around the relevance of the intervention given the current environment of multiple fluoride sources and a reported increase in the prevalence of enamel fluorosis. The aim of this economic analysis is to provide evidence to inform policy decisions on whether the continued public investment in community water fluoridation remains justified under these altered circumstances. METHODS: Following traditional methods of economic evaluation and using epidemiological data from a representative sample of 5-, 8-, and 12-year-old schoolchildren, this cost-effectiveness analysis, conducted from the health-payer perspective, compared the incremental costs and consequences associated with the CWF intervention to no intervention for schoolchildren living in Ireland in 2017. A probabilistic model was developed to simulate the potential lifetime treatment savings associated with the schoolchildren's exposure to the intervention for one year. RESULTS: In 2017, approximately 71% of people living in Ireland had access to a publicly provided fluoridated water supply at an average per capita cost to the state of 2.15. The total cost of CWF provision to 5-, 8-, and 12-year-old schoolchildren (n = 148,910) was estimated at 320,664, and the incremental cost per decayed, missing, or filled tooth (d3vcmft/D3vcMFT) prevented was calculated at 14.09. The potential annual lifetime treatment savings associated with caries prevented for this cohort was estimated at 2.95 million. When the potential treatment savings were included in the analysis, the incremental cost per d3vcmft/D3vcMFT prevented was -115.67, representing a cost-saving to the health-payer and a positive return on investment. The results of the analysis were robust to both deterministic and probability sensitivity analyses. CONCLUSION: Despite current access to numerous fluoride sources and a reported increase in the prevalence of enamel fluorosis, CWF remains a cost-effective public health intervention for Irish schoolchildren.

BACKGROUND: Dental plaque associated gingivitis is a reversible inflammatory condition caused by accumulation and persistence of microbial biofilms (dental plaque) on the teeth. It is characterised by redness and swelling of the gingivae (gums) and a tendency for the gingivae to bleed easily. In susceptible individuals, gingivitis may lead to periodontitis and loss of the soft tissue and bony support for the tooth. It is thought that chlorhexidine mouthrinse may reduce the build-up of plaque thereby reducing gingivitis. OBJECTIVES: To assess the effectiveness of chlorhexidine mouthrinse used as an adjunct to mechanical oral hygiene procedures for the control of gingivitis and plaque compared to mechanical oral hygiene procedures alone or mechanical oral hygiene procedures plus placebo/control mouthrinse. Mechanical oral hygiene procedures were toothbrushing with/without the use of dental floss or interdental cleaning aids and could include professional tooth cleaning/periodontal treatment.To determine whether the effect of chlorhexidine mouthrinse is influenced by chlorhexidine concentration, or frequency of rinsing (once/day versus twice/day).To report and describe any adverse effects associated with chlorhexidine mouthrinse use from included trials. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 28 September 2016); the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 8) in the Cochrane Library (searched 28 September 2016); MEDLINE Ovid (1946 to 28 September 2016); Embase Ovid (1980 to 28 September 2016); and CINAHL EBSCO (Cumulative Index to Nursing and Allied Health Literature; 1937 to 28 September 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included randomised controlled trials assessing the effects of chlorhexidine mouthrinse used as an adjunct to mechanical oral hygiene procedures for at least 4 weeks on gingivitis in children and adults. Mechanical oral hygiene procedures were toothbrushing with/without use of dental floss or interdental cleaning aids and could include professional tooth cleaning/periodontal treatment. We included trials where participants had gingivitis or periodontitis, where participants were healthy and where some or all participants had medical conditions or special care needs. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the search results extracted data and assessed the risk of bias of the included studies. We attempted to contact study authors for missing data or clarification where feasible. For continuous outcomes, we used means and standard deviations to obtain the mean difference (MD) and 95% confidence interval (CI). We combined MDs where studies used the same scale and standardised mean differences (SMDs) where studies used different scales. For dichotomous outcomes, we reported risk ratios (RR) and 95% CIs. Due to anticipated heterogeneity we used random-effects models for all meta-analyses. MAIN RESULTS: We included 51 studies that analysed a total of 5345 participants. One study was assessed as being at unclear risk of bias, with the remaining 50 being at high risk of bias, however, this did not affect the quality assessments for gingivitis and plaque as we believe that further research is very unlikely to change our confidence in the estimate of effect. Gingivitis After 4 to 6 weeks of use, chlorhexidine mouthrinse reduced gingivitis (Gingival Index (GI) 0 to 3 scale) by 0.21 (95% CI 0.11 to 0.31) compared to placebo, control or no mouthrinse (10 trials, 805 participants with mild gingival inflammation (mean score 1 on the GI scale) analysed, high-quality evidence). A similar effect size was found for reducing gingivitis at 6 months. There were insufficient data to determine the reduction in gingivitis associated with chlorhexidine mouthrinse use in individuals with mean GI scores of 1.1 to 3 (moderate or severe levels of gingival inflammation). Plaque Plaque was measured by different indices and the SMD at 4 to 6 weeks was 1.45 (95% CI 1.00 to 1.90) standard deviations lower in the chlorhexidine group (12 trials, 950 participants analysed, high-quality evidence), indicating a large reduction in plaque. A similar large reduction was found for chlorhexidine mouthrinse use at 6 months. Extrinsic tooth staining There was a large increase in extrinsic tooth staining in participants using chlorhexidine mouthrinse at 4 to 6 weeks. The SMD was 1.07 (95% CI 0.80 to 1.34) standard deviations higher (eight trials, 415 participants analysed, moderate-quality evidence) in the chlorhexidine mouthrinse group. There was also a large increase in extrinsic tooth staining in participants using chlorhexidine mouthrinse at 7 to 12 weeks and 6 months. Calculus Results for the effect of chlorhexidine mouthrinse on calculus formation were inconclusive. Effect of concentration and frequency of rinsing There were insufficient data to determine whether there was a difference in effect for either chlorhexidine concentration or frequency of rinsing. Other adverse effects The adverse effects most commonly reported in the included studies were taste disturbance/alteration (reported in 11 studies), effects on the oral mucosa including soreness, irritation, mild desquamation and mucosal ulceration/erosions (reported in 13 studies) and a general burning sensation or a burning tongue or both (reported in nine studies). AUTHORS' CONCLUSIONS: There is high-quality evidence from studies that reported the Löe and Silness Gingival Index of a reduction in gingivitis in individuals with mild gingival inflammation on average (mean score of 1 on the 0 to 3 GI scale) that was not considered to be clinically relevant. There is high-quality evidence of a large reduction in dental plaque with chlorhexidine mouthrinse used as an adjunct to mechanical oral hygiene procedures for 4 to 6 weeks and 6 months. There is no evidence that one concentration of chlorhexidine rinse is more effective than another. There is insufficient evidence to determine the reduction in gingivitis associated with chlorhexidine mouthrinse use in individuals with mean GI scores of 1.1 to 3 indicating moderate or severe levels of gingival inflammation. Rinsing with chlorhexidine mouthrinse for 4 weeks or longer causes extrinsic tooth staining. In addition, other adverse effects such as calculus build up, transient taste disturbance and effects on the oral mucosa were reported in the included studies.

BACKGROUND: A previous study has shown deficient knowledge of caries risk factors/indicators in a Japanese adult population regarded to have a high interest in preventive dentistry. No prior research has investigated caries risk knowledge in an Irish adult population. We hypothesise there may be unexpected differences or similarities in knowledge across countries with similar levels of economic development when comparing groups with different socio-economic and cultural profiles. Understanding what influences knowledge is important for the development of effective and efficient caries prevention strategies. The current paper aims to describe the knowledge of caries risk factors/indicators in two groups with different socio-economic profiles from two culturally distinct countries. METHODS: Cross-sectional surveys of adult dental patients were carried out in Japan and in the Republic of Ireland (RoI) using similar self-administered paper questionnaires. Patients were asked to identify caries risk factors/indicators from eight (Japan) or ten (RoI) listed items. The Japanese study involved 482 patients (aged ≥20 years) from 52 dental members of a nationwide web-based initiative Promoting Scientific Assessment in Prevention of Tooth Decay and Gum Disease (PSAP). The Irish study involved 159 patients (aged 20-69 years) accessing state-provided ('medical card') dental services from eight dental practices in County Cork. The two samples were compared. RESULTS: A higher proportion of Irish respondents identified 'Not visiting the dentist for check-up and cleaning' (OR 2.655; 99% CI 1.550, 4.547) and 'Not using fluoride' (OR 1.714; 99% CI 1.049, 2.802) than did Japanese respondents. A lower proportion of Irish respondents identified 'A reduced amount of saliva' (OR 0.262; 99% CI 0.159, 0.433) than Japanese respondents. Similarly shown in both studies were a persistent belief that 'Not brushing teeth properly' is a caries risk factor and a lack of knowledge on saliva buffering capacity as a caries risk factor. CONCLUSIONS: Deficiencies in knowledge which should be addressed: among the Japanese group, of dental check-up/cleaning visits and of fluoride use for caries prevention; among the Irish group, of saliva quantity as a caries risk factor. In addition, in both groups, we need to inform patients of the defensive role of saliva.

Internationally, a considerable proportion of children aged five years and younger require extraction of teeth due to dental caries and frequently dental general anaesthesia (DGA) is the treatment of choice. AIMS: To investigate the records of a cohort of preschool children (aged five years and younger) referred to the public dental service provided at Cork University Hospital (CUH), Cork, Ireland, for extractions under DGA between the years 2000 and 2002. To determine the characteristics of the sample: disadvantage; the presence of a significant medical history; and, fluoride status. To establish the pattern of appointments and care, before, during and after DGA, and the pattern of dental treatment required up to sixth class (aged 11 to 12 years). METHODS: A retrospective review of dental records of a cohort of preschool-aged children referred for DGA in CUH during the years 2000-2002 was completed. Demographic and clinical data were collated and analysed using Statistical Packages for Social Sciences (SPSS). Costs were provided by CUH and the Health Service Executive (HSE). Data on costs relating to preventive programmes were obtained from information presented in the Irish Oral Health Services Guideline Initiative 2009. RESULTS: A total of 347 children were included with a median age of.fQur years and a range of one to five years. Children with a disadvantage were more likely to require extractions under DGA than their- counterparts (50%, n=175). In total, 73% (n=253)~ of patients had a fluoridated water supply and 91% (n=316) had no adverse medical history. For 88% (n=306), their first dental visit was an emergency appointment. The primary indication for DGA was treatment of dental caries. A recall appointment was provided for 18% (n=63). One-quarter (n=86) required an extraction, antibiotic or referral for a second DGA at their first visit following DGA. In first class, referral for a second DGA or extraction under local anaesthetic (LA) was required for 23% (n=79) of patients. Over 60% (n=21 1) required either an extraction or a restoration in third class. In excess of 20% (n=69) of patients did not attend the sixth class dental inspection, the final assessment appointment in the public services. CONCLUSIONS: A considerable number of preschool children require extractions under DGA due to dental caries. The results of this study indicate that such children progress to adolescence with poor oral health, as evidenced by the need for further restorations, extractions and repeat DGA. The average cost of DGA was E819 per child. This figure has been shown to be as much as eight times the cost of a preventive/oral health promotion prograrnme operating within a similar cohort. An integrated preventive programme targeting preschool-aged children should be considered in attempting to manage the hicih levels of dental caries within this age group.

Fluoride is added to drinking water in some countries to prevent tooth decay (caries). There is no conclusive evidence that community water fluoridation (CWF) at WHO recommended concentrations for caries prevention has any harmful effects. However, research is ongoing regarding potential effects of ingested fluoride on human neurodevelopment and endocrine dysfunction. Simultaneously, research has emerged highlighting the significance of the human microbiome in gastrointestinal and immune health. In this review we evaluate the literature examining the effect of fluoride exposure on the human microbiome. Unfortunately, none of the studies retrieved examined the effects of ingested fluoridated water on the human microbiome. Animal studies generally examined acute fluoride toxicity following ingestion of fluoridated food and water and conclude that fluoride exposure can detrimentally perturb the normal microbiome. These data are difficult to extrapolate to physiologically relevant human exposure dose ranges and the significance to humans living in areas with CWF requires further investigation. Conversely, evidence suggests that the use of fluoride containing oral hygiene products may have beneficial effects on the oral microbiome regarding caries prevention. Overall, while fluoride exposure does appear to impact the human and animal microbiome, the long-term consequences of this requires further study.

Background-The recent burden of lip and oral cavity, nasopharynx and other pharynx cancer (LOCP) has not been specifically investigated in Europe. Methods-In this descriptive epidemiological study, LOCP was categorised into lip and oral cavity cancer, nasopharynx cancer and other pharynx cancer, with European trends documented using the 2019 Global Burden of Disease (GBD). Summary statistics included deaths, age-standardised incidence rates (ASIR), mortality rates, YLLs (years of life lost), YLDs (years of life lived with disability) and DALYS (disability-adjusted life years). Results-Lip and oral cavity cancer (LO) is the most dominant with the incidence decreasing from 6.2 new cases per 100,000 (95% UI: 6.1-6.4) in 1990 to 5.3 new cases per 100,000 (95% UI: 4.6-6.1). However, nasopharynx cancer (NP) and other pharynx cancer (OP) increased from 1 and 2.2 new cases per 100,000 in 1990 to 1.1 and 3.3 new cases per 100,000 in 2019, respectively. It was noted that LOCP YLLs is much higher than YLDs. In Europe, eastern European countries, specifically Hungary, have the highest burden of LOCP. When LOCP attributable to tobacco in Ireland was compared with the EU, the percentage decrease in OP DALYs attributable to tobacco is below the EU average, whereas the percentage decrease in LO attributable to tobacco in Ireland was above the EU average. Conclusions-There has been a significant increase in ASIR in categories other pharynx and nasopharynx cancer since 1990, with significant geographic variations.

Background: Oral diseases have the highest global prevalence rate among all diseases, with dental caries being one of the most common conditions in childhood. A low political priority coupled with a failure to incorporate oral health within broader health systems has contributed to its neglect in previous decades. In response, calls are emerging for the inclusion of oral health within the universal healthcare domain (UHC). This protocol outlines the methodology for a cross-country comparative analysis of publicly funded oral health systems for children across six European countries, reporting on oral health status in line with the indicators for UHC. Methods: This study will follow Yin's multiple case study approach and employ two strands of data collection, analysis, and triangulation: a systematic documentary analysis and semi-structured interviews with elite participants local to each country. The countries chosen for comparison and providing a representative sample of European dental systems are Denmark, Hungary, the Republic of Ireland, Germany, Scotland, and Spain. A systematic search of five electronic databases and four additional electronic resources will be undertaken, in addition to grey literature and other publicly available sources, with the outcomes verified and further informed by local experts. The WHO Universal Health Coverage Cube will be used to guide data collection and analysis. Conclusions: This research will provide policy makers with an in-depth analysis and comparison of publicly funded oral health systems for children in Europe, including consideration of effective preventive strategies, oral health system reform, and indicators of universal oral health coverage. It is anticipated that the outcomes may help in positioning oral health on governmental health agendas and support its integration into wider health systems' reform in an accessible and affordable manner.
ABSTRACT
OBJECTIVE: We aimed to quantify aerosol concentrations produced during different dental procedures under different mitigation processes. METHOD: Aerosol concentrations were measured by the Optical Particle Sensor (OPS) and Wideband Integrated Bioaerosol Sensor (WIBS) during routine, time-recorded dental procedures on a manikin head in a partitioned enclosure. Four different, standardised dental procedures were repeated in triplicate for three different mitigation measures. RESULT: Both high-volume evacuation (HVE) and HVE plus local exhaust ventilation (LEV) eradicated all procedure-related aerosols, and the enclosure stopped procedure-related aerosols escaping. Aerosols recorded by the OPS and WIBS were 84 and 16-fold higher than background levels during tooth 16 FDI notation (UR6) drilling, and 11 and 24-fold higher during tooth 46 FDI notation (LR6) drilling, respectively. Ultrasonic scaling around the full lower arch (CL) or the full upper arch (CU) did not generate detectable aerosols with mitigation applied. Without mitigation the largest concentration of inhalable particles during procedures observed by the WIBS and OPS was during LR6 (139/cm3) and UR6 (28/cm3) drilling, respectively. Brief aerosol bursts were recorded during drilling procedures with HVE, these did not occur with LEV, suggesting LEV provides protection against operator errors. Variation was observed in necessary fallow times (49 - 280 minutes) without mitigation, while no particles remained airborne when mitigation was utilised. CONCLUSION: This data demonstrates that correctly positioned HVE or LEV is effective in preventing airborne spread and persistence of inhalable particles originating from dental AGPs. Additionally, a simple enclosure restricts the spread of aerosols outside of the operating area. CLINICAL SIGNIFICANCE: Employing correctly positioned HVE and LEV in non-mechanically ventilated clinics can prevent the dispersal and persistence of inhalable airborne particles during dental AGPs. Moreover, using enclosures have the additive effect of restricting aerosol spread outside of an operating area.

AIMS: This research synthesis protocol addresses the question: what is the evidence concerning measurement properties of dental patient reported outcome measures (dPROMs), and regarding the real-world value of dPROMs, and where are the gaps in this evidence? Evidence mapping will systematically examine reviews of quantitative dPROMs used to assess the impact of oral health on the quality of life of dental patients and research participants. Evidence gaps where future research or systematic reviews are required will be identified. MATERIALS AND METHODS: This protocol accords with the PRISMA-P guideline. Open Science Framework Registration https://doi.org/10.17605/OSF.IO/RZD3N . Biomedical and grey literature databases will be searched, adapting the same search strategy. Published or unpublished reviews evaluating any dPROM will be considered for inclusion. There will be no restriction by date, setting, or language. AMSTAR2 and ROBIS will evaluate risk of bias. Psychometric criteria will be adapted from COSMIN. Data will be summarised separately for specific populations and conditions. DISCUSSION: The findings will enable clinicians and researchers to identify methodologically robust dPROMs, appropriate for use with relevant populations and conditions. Implications for real-world practice and research will be discussed.
ABSTRACT
Background: The prevalence of overweight and obesity among children may have reached a plateau in some developed countries, including Ireland. The aim of this study was to examine 12-year trends in the prevalence of overweight and obesity among primary-school-aged children in the Republic of Ireland between 2002 and 2014. Methods: Two large-scale oral health cross-sectional surveys of primary-school-aged children aged 4-13 years were conducted 12 years apart in 2002 (n=14,055; response rate=68%) and 2014 (n=5,223; response rate=67%). Both surveys included standardised and calibrated height and weight measures. Ownership of a means-tested medical card determined economic status. Standard International Obesity Task Force criteria were applied to determine the prevalence of overweight and obesity. Results: The overall prevalence of overweight/obesity among 4-13-year-olds significantly decreased from 26% (95% CI: 25.1%-26.5%) in 2002 to 24% (95% CI: 22.4%-24.7%) in 2014. Among boys and girls aged 4-13 years, the significant decrease was from 23% (95% CI: 22.1%-24.1%) to 20% (95% CI: 18.9%-22.0 and 28% (95% CI: 27.4%-29.5%) to 27% (95% CI: 25.0%-28.4%), respectively. Among 5-year-old children, the overall prevalence of overweight and obesity significantly decreased from 25% (95% CI: 23.7%-26.2%) to 22% (95% CI: 19.9%-23.4%). In 2002, the estimated prevalence of overweight/obesity was similar in children with and without medical cards, whereas in 2014, overall prevalence was higher in those with medical cards. Conclusions: Results suggest a fall in the prevalence of overweight/obesity between 2002 and 2014, and may suggest a favourable cohort effect. Despite this fall, the overall prevalence remains high and socioeconomic disparities have increased.
ABSTRACT
Background: The reduction in dental caries seen between Irish national surveys of children's oral health in 1984 and 2002 was accompanied by an increase in the prevalence of enamel fluorosis. To minimise the risk of enamel fluorosis in Irish children, in 2007, the level of fluoride in drinking water was reduced from 0.8-1.0 ppm to 0.6-0.8 ppm fluoride. Recommendations on the use of fluoride toothpastes in young children were issued in 2002. Fluoride and Caring for Children's Teeth (FACCT) is a collaborative project between the Oral Health Services Research Centre, University College Cork and the Health Service Executive dental service, with funding from the Health Research Board. Aim: FACCT aims to evaluate the impact and the outcome of the change in community water fluoridation (CWF) policy (2007) on dental caries and enamel fluorosis in Irish schoolchildren, while also considering the change in policy on the use of fluoride toothpastes (2002). Methods/Design: A cross-sectional study with nested longitudinal study will be conducted in school year (SY) 2013-2014 by trained and calibrated dental examiners in primary schools in counties Dublin, Cork and Kerry for a representative sample of children born either prior to or post policy changes; age 12 (born 2001) and age 5, (born 2008). Five-year-olds will be followed-up when they are 8-year-olds (SY 2016-2017). The main explanatory variable will be fluoridation status of the children (lifetime exposure to CWF yes/no). Information about other explanatory variables will be collected via parent (of 5-, 8- and 12-year-olds) and child completed (8- and 12-year-olds only) questionnaires. The main outcomes will be dental caries (dmf/DMF Index), enamel fluorosis (Dean's Index) and oral health-related quality of life (OHRQoL). Multivariate regression analyses will be used to determine the impact and outcome of the change in CWF policy on oral health outcomes controlling for other explanatory variables.
ABSTRACT
OBJECTIVES/AIMS: To evaluate continuous and episodic twice-daily usage regimens of a desensitising dentifrice containing 5% calcium sodium phosphosilicate (CSPS). MATERIALS AND METHODS: In this exploratory, single-centre, randomised, examiner-blind study, subjects with dentinal hypersensitivity were randomised to continuous (24 weeks) use of a 5% CSPS-containing dentifrice or episodic use of the dentifrice comprising two 8-week treatment periods separated by 8 weeks' use of a standard fluoride dentifrice. Sensitivity was assessed by tactile threshold (Yeaple probe) and evaporative (air) sensitivity (Schiff sensitivity score). Other measures included labelled magnitude scales to assess subjects' responses to the evaporative stimulus, the Dentine Hypersensitivity Experience Questionnaire and a tooth sensitivity question. RESULTS: Seventy-six subjects were randomised to continuous (n=38) or episodic (n=38) use. Small but statistically significant improvements from baseline in Schiff sensitivity scores were observed at weeks 8, 16 and 24 with both regimens (all P<0.05). Increases from baseline in tactile threshold were not statistically significant. No significant between-regimen difference was observed for any endpoint. No treatment-related adverse events were reported. DISCUSSION: Dentifrice containing 5% CSPS improved dentinal hypersensitivity with both episodic and continuous twice-daily usage regimens over 24 weeks and was well tolerated. CONCLUSION: No performance differences were observed between the two usage regimens.
ABSTRACT
UNLABELLED: Water fluoridation, is the controlled addition of fluoride to the water supply, with the aim of reducing the prevalence of dental caries. Current estimates suggest that approximately 370 million people in 27 countries consume fluoridated water, with an additional 50 million consuming water in which fluoride is naturally occurring. A pre-eruptive effect of fluoride exists in reducing caries levels in pit and fissure surfaces of permanent teeth and fluoride concentrated in plaque and saliva inhibits the demineralisation of sound enamel and enhances the remineralisation of demineralised enamel. A large number of studies conducted worldwide demonstrate the effectiveness of water fluoridation. Objections to water fluoridation have been raised since its inception and centre mainly on safety and autonomy. Systematic reviews of the safety and efficacy of water fluoridation attest to its safety and efficacy; dental fluorosis identified as the only adverse outcome. CONCLUSION: Water fluoridation is an effective safe means of preventing dental caries, reaching all populations, irrespective of the presence of other dental services. Regular monitoring of dental caries and fluorosis is essential particularly with the lifelong challenge which dental caries presents.
