Caries lesions progression in adults: A prospective 2-year cohort study.

Dental caries is one of the most prevalent chronic non-communicable diseases worldwide. There is a lack of evidence, especially in adult populations, documenting caries disease progression considering lesion severity, activity and tooth surface-level characteristics. The study aimed to investigate the extent to which primary active caries lesions in adults affect caries lesions progression compared with inactive caries lesions over a 2-year follow-up period, considering their severity, surface and tooth type. A prospective study data set from a cohort of workers in a factory in Belarus were used. Participants aged 18-64 years with 20 or more natural teeth were included in the study. The participants were clinically examined twice within an interval of 2 years and completed a self-reported questionnaire. One calibrated examiner evaluated caries lesions using the International Caries Detection and Assessment System (ICDAS) and the Nyvad system. The primary outcome was caries lesions' progression. The lesion was classified as 'progressed' if it turned to a more advanced severity stage, was restored or missing/extracted due to caries. A multilevel Poisson regression was used to estimate the association between baseline caries lesions' characteristics and caries lesion progression. Out of 495 participants, 322 people completed clinical examinations at baseline and 2 years later, with an attrition rate of 35%. The prevalence of active DS1-6 and DS5-6 lesions at the baseline was 83.8% and 64.8%, respectively. In 2 years, 24% of active non-cavitated and 31% of active micro-cavitated/shadowed caries lesions progressed, while 15% of inactive caries lesions, non- or micro-cavitated/shadowed, progressed. The adjusted rate ratio (RR) for ICDAS3 + 4 caries lesions progression was 1.41 (CI 95% 1.16, 1.70) than ICDAS1 + 2 lesions. The RR for ICDAS1 + 2, active and ICDAS3 + 4, active lesions was 1.78 (CI 95%, 1.40, 2.27) and 1.97 (CI 95%, 1.53, 2.55), respectively than ICDAS1 + 2, inactive lesions. The RR for caries lesions progression on proximal surfaces and on pits and fissures was 1.57 (CI 95%, 1.30, 1.89) and 1.37 (CI 95%, 1.11, 1.67), respectively than smooth surface lesions. In caries active adults over 2 years, most non- and micro-cavitated/shadowed active and inactive caries lesions did not progress. Among caries lesions that showed progression, more severe lesions were more likely to progress than less severe lesions; active lesions were more likely to progress than inactive lesions. Pit and fissure caries lesions and proximal lesions were more likely to progress than smooth surface lesions.

School composition and academic achievement: The case of Russian-medium and Polish-medium schools in Lithuania

After Lithuania re-gained its independence, linguistic and cultural minority groups residing in the country had the right to be educated in non-Lithuanian-medium schools. Yet, the education of linguistic minority children has been a contentious topic in Lithuania for many years, and there is no conclusive evidence on how minority-language-medium schools in Lithuania perform academically, with national assessment suggesting that they perform worse than Lithuanian-speaking schools, and international assessment showing mixed results. Our research focuses on Russian- and Polish-medium schools and analyses the difference in academic performance among children attending Lithuanian-medium school and minority-language schools, as well as its reasons and social implications. Using the OECD Program for International Student Assessment (PISA) data, we find that minority-language children perform better when attending a school in which the language of instruction is the same as their home language.

Detection of soil-transmitted helminths and Schistosoma spp. by nucleic acid amplification test: Results of the first 5 years of the only international external quality assessment scheme.

Infections with soil-transmitted helminths (STH) and schistosomiasis (SCH) result in a significant global health burden, particularly in rural communities in low and middle-income countries. While microscopy remains the primary diagnostic method for STH and SCH in resource-limited settings, nucleic acid amplification tests (NAATs) are gaining prominence as tools for evaluation of public health control programs in endemic countries, and individual diagnosis in high-income countries. Despite the high sensitivity and specificity of NAATs, previous research has highlighted inter-laboratory variations, both in technical and clinical performance, justifying the need for continuous proficiency testing. Results from 5 rounds over a 5-year period of the so far only longitudinal international Helminth External Molecular Quality Assessment Scheme (HEMQAS), coordinated by the Dutch Foundation for Quality Assessment in Medical Laboratories (SKML), were examined in order to (i) assess the diagnostic proficiency of laboratories in detecting helminths in stool and (ii) identify potential factors contributing to variations in performance. Thirty-six laboratories, from 18 countries and 5 continents, participated in HEMQAS. The overall diagnostic performances were satisfying, with remarkably low numbers (<2%) of false-positive results. False-negative results were more often reported for stool (15%) than for DNA (5%) samples. False-negative results varied largely between targets (the highest number (29%) for Trichuris trichiura). Twenty-five laboratories provided a sufficient number of results for a robust comparison between participating laboratories, which confirmed substantial inter-laboratory variability in quantitative NAAT results (Cq-values). This variability likely arises from differences in pre-treatment, DNA isolation and DNA-target amplification procedures. This study emphasizes the complexity of molecular diagnosis for STH and SCH, highlighting the critical role of proper stool preparation and DNA isolation methods. The results underscore the necessity for laboratory professionals and public health decision-makers to recognize these complexities and continuously undertake external quality assessment schemes to ensure accurate and reliable performance in molecular diagnosis.

Diagnostic agreement between visual examination and an automated scanner system with fluorescence for detecting and classifying occlusal carious lesions in primary teeth

ObjectivesTo investigate the in vivo diagnostic agreement between visual examination (VE) using the International Caries Detection and Assessment System (ICDAS) and an automated scanner system for detecting and classifying carious lesions in primary teeth. Methods5-year-old children (n = 216) underwent VE and intraoral scanning (TRIOS 4, 3Shape TRIOS A/S, Copenhagen, Denmark). Dental caries experience was recorded for each tooth surface using ICDAS. An automated, fluorescence-based caries scoring system was applied to eligible primary teeth occlusal surfaces on the 3D models using commercially available software. The automated system classified surfaces as sound, initial caries (ICDAS 01/02), or moderate-extensive caries (ICDAS ≥03). The diagnostic agreement was investigated using multi-level modelling and intraclass correlation coefficients. Analyses were repeated at both the initial threshold (ICDAS ≥01) and the moderate-extensive threshold (ICDAS ≥03). Results213 participants were included in the study, and 1525 primary molar occlusal surfaces were included in the analysis. The odds of detecting caries using the automated system were 46 % lower at the initial disease threshold (OR 0.54, 95 % CI 0.39–0.74) and 70 % lower at the moderate-extensive disease threshold (OR 0.30, 95 % CI 0.16–0.58) compared to VE. The intraclass correlation estimates at the initial and moderate-extensive thresholds were 0.90 (95 % CI 0.70–0.96) and 0.76 (95 % CI 0.22–0.94) respectively. ConclusionThe automated system is less likely to detect initial lesions and is more likely to underestimate lesion severity relative to visual examination using ICDAS. Clinical SignificanceClinically, using the automated tool to replace thorough visual inspection in primary teeth could result in missed opportunities to provide professional or self-care to arrest or reverse early disease. Additionally, it could misclassify moderate lesions as initial caries, potentially leading to complications associated with the delayed management of dental caries.

The Impact of Realistic Mathematics Education-based Student Worksheet for Improving Students’ Mathematical Problem-Solving Skills

&lt;p&gt;&lt;span lang="EN-US"&gt;Mathematical problem-solving ability is a critical skill required to meet the challenges of the 21st century, making it imperative for Indonesian students to master these skills. However, international assessments have consistently shown that Indonesian students' competencies, particularly in mathematical problem-solving, remain low. Research attributes this deficiency to the lack of connections between mathematical concepts and real-life applications, which are essential for enhancing problem-solving skills. On the other hand, Realistic Mathematics Education (RME) is a learning approach that emphasizes the integration of real-world contexts in learning activities and has been shown to improve these skills. Therefore, this study aims to develop a student worksheet based on the RME approach to enhance students' problem-solving abilities. The development process followed the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. Various research and development instruments were employed, including validation by material and media experts, student assessments of the electronic worksheets, and pre-test and post-test evaluations. Data collection methods encompassed both non-test and test techniques. The results demonstrate that the developed student worksheets are valid, practical, and effective. The validity was confirmed by high average scores from material and media expert validators, categorizing the worksheets as valid. Practicality was supported by positive student assessments, placing the worksheets in the practical category. These findings indicate that the developed worksheets significantly enhance students' problem-solving abilities. This study provides empirical evidence supporting the effectiveness of the RME approach in improving mathematical problem-solving skills among Indonesian students. It also offers a theoretical and practical framework for advancing mathematics education in Indonesia, advocating for the adoption of learning approaches that better address the demands of the 21st century. Detailed analysis of the product's acceptability and impact will be discussed further in the paper.&lt;/span&gt;&lt;/p&gt;

Diagnostic Efficacy of Ultrasound-Based International Ovarian Tumor Analysis Simple Rules and Assessment of the Different Neoplasias in the Adnexa Model in Malignancy Prediction Among Women With Adnexal Masses: A Systematic Review.

Transvaginal ultrasonography (USG) is most commonly used before surgery to accurately diagnosebenign and malignant ovarian massesfor effectivetreatment, avoid unnecessary interventions,improve the prognosis of patients,and preserve fertility in patients with benigntumors. Therefore, the objective of the present systematic review was to assess the diagnostic efficacy of ultrasound-based International Ovarian Tumor Analysis (IOTA) Simple Rules (SR) and Assessment of Different NEoplasias in the adneXa (ADNEX) model in predicting malignancy among women with adnexal masses. A systematic literature search was carried out on electronic databases consisting of Science Direct, PubMed, and Google Scholar. The keywords utilized to perform the literature search and include relevant articles consisted of "Diagnostic Efficacy", AND "Ultrasound-Based International Ovarian Tumor Analysis Simple Rules", AND "International Ovarian Tumor Analysis ADNEX Model", AND "Adnexal masses", AND "Ovarian tumors". Based on the selection criteria, a total of five studies were included. The study concluded that both the models showed high diagnostic efficacy for malignancy prediction; however, in comparison to the IOTA SR, the IOTA ADNEX model demonstrated good diagnostic efficacy.

Investigating prison factors related to literacy and numeracy skills of incarcerated adults

Incarcerated adults in the United States are a vulnerable group with substantially low skills and educational attainment. However, the extent to which various, malleable prison factors are related to the skills of adults from diverse backgrounds remains scarcely explored. Therefore, the purpose of the present study was to explore such factors in order to examine which prison programs and activities are associated with higher skills for incarcerated adults in the United States. The sample included 1247 inmates who participated in the Program for the International Assessment of Adult Competencies survey. Regression analysis results revealed that completing more than high school education in prison was linked to higher performance in literacy and numeracy. Also, higher performance was associated with more time in prison, suggesting that program benefits for inmates with shorter time in prison might go unnoticed. Lastly, the most notable differences in performance were related to participation in prison job training. Even though many incarcerated adults partake in various prison programs and activities, participation in these programs was not consistently associated with higher literacy or numeracy skills. Potentially, prison programs might not be providing sufficient applied opportunities for enhancing skills. Findings from this study suggest a need for a closer evaluation of the malleable prison factors and programs relating to the literacy and numeracy skills of incarcerated adults in the United States.

Exploring profiles of engagement in reading, numeracy, writing, and computer skills-use of U.S. adults with low literacy skills

This study uses Program for the International Assessment of Adult Competencies (PIAAC) data to examine latent profiles of engagement in reading, numeracy, writing, and computer skills-use for U.S. adults with low literacy skills. Additionally, we examine how these profiles relate to overall literacy performance and demographic heterogeneity. Results indicate five engagement profiles: High (8%), Average-High (44%), Average-Low (40%), and two generally Low profiles that are most differentiated on numeracy skills-use engagement (5.5%, 2%). High and Average-High engagement profiles had higher probabilities of adults scoring at a higher literacy level than the Average-Low profile and to a greater degree than the lowest engagement profile. Covariates of learning disability status, English speaker status, race, ethnicity, age, and educational attainment were also related to differences in literacy performance and skills-use engagement. Employment status was unrelated to differences in literacy performance and skills-use engagement. Generally, native English speakers, non-learning disabled adults, younger adults, those identifying as non-Hispanic and White, and adults with higher educational attainment (high school/some college and college degree or higher) had higher probabilities of higher literacy performance, particularly in the High and Average-High engagement profiles. Findings have implications for increasing skills-use engagement in daily life to increase literacy performance and suggest differences by demographic characteristics that may be of interest to adult foundational education programs.

KETERAMPILAN MEMBACA PEMAHAMAN MATERI RAGAM TEKS BERBASIS HOTS DI SD: STUDI LITERATUR

This research aims to examine the very low reading comprehension skills in Indonesia. It can be seen that the position of students' reading literacy skills in Indonesia from the results of several PIRLS surveys in 2006, IEA 2011, and PISA in 2018 can be categorized as very worrying. This international research assessment standard refers to advanced reading (comprehension) or what is often called HOTS (High Order Thinking Skills). The purpose of this article is to provide information regarding Indonesian students' ability to read comprehension with HOTS-based text variation material in Indonesian language learning, both regarding various problems that result in low reading comprehension skills and how to improve reading comprehension skills in elementary schools. This research uses qualitative research methods by studying literature or literature studies using several sources of written literature, data, and book references and other scientific journal articles. The results of the research show that reading comprehension problems are caused by incorrect comprehension orientation regarding advanced reading levels and lack of variety in learning to read questions in elementary schools so that reading comprehension skills are very low.

Can the improvements in human capital quality mitigate the negative impact of ageing on growth? Evidence from selected EU countries

AbstractMost long‐term GDP projections in developed countries expect a substantial decline in GDP growth rates over time. The main factor behind it is demographic changes, especially the decreasing working‐age population. We argue that these projections do not consider improvements in the quality of the human capital, which may, at least to some extent, mitigate the effects of the negative demographic shock. We start with a simple observation—the skills of younger age cohorts are higher than of older cohorts. Assuming that the current level of skills will be obtained also by the generations which will enter the labour market in the future, the average level of skills among the working‐age population will increase. Trying to catch this effect, we use the Programme for the International Assessment of Adult Competencies standardised test results to create an aggregate human capital measure, the average skill level of the work force, for 18 European Union countries and project it until 2040. We show that on average at least one sixth of the negative impact of the shrinking of the working‐age population can be offset by the increase in the quality of human capital and that this number can increase to three quarters in a less conservative scenario.

Photoactivated rose bengal-doped TiO2 nanoparticles modified fifth-generation adhesive on the survival rate of Streptococcus mutants and mechanical properties of tooth-colored restorative material to carious dentin.

Assessment of the antimicrobial, micro tensile bond strength (μTBS), and degree of conversion (DC) of fifth-generation adhesive modified using photoactivated 0.5% rose bengal (RB) and photoactivated RB-doped titanium dioxide nanoparticles (TiO2NPs) in different concentrations (2% and 5%) as compared with the unmodified adhesive bonded to the carious affected dentin (CAD). Forty mandibular molars with caries progression up to the middle third of the dentin, as per the International Caries Detection and Assessment System (ICDAS) score of 4 and 5 were included. Specimens were divided into four groups based on etch and rinse adhesive (ERA) modification group 1: unmodified ERA, group 2: photoactivated 0.5% RB photosensitizer (PS) modified ERA, group 3: photoactivated RB-doped 2 wt% TiO2NPs adhesive, group 4: photoactivated RB-doped 5 wt% TiO2NPs adhesive. Followed by adhesive and composite restoration on the CAD surface. All the specimens were thermocycled and an assessment of μTBS and failure pattern analysis was performed. The antibacterial potency of RB and RB-doped TiO2NPs (2% and 5%) followed by their activation using visible light against Streptococcus mutans (S.mutans) were tested. The survival rate of S.mutans was assessed using the Kruskal-Wallis test. The analysis of μTBS involved the use of ANOVA, followed by a post-hoc Tukey honestly significant difference (HSD) multiple comparisons test. Group 1 (Unmodified ERA) (0.52 ± 0.31 CFU/mL) treated samples unveiled the highest means of bacterial survival and lowest μTBS (11.32 ± 0.63 MPa). Nevertheless, group 4: photoactivated RB-doped 5 wt% TiO2NPs adhesive displayed the lowest outcomes of S.mutans survival (0.11 ± 0.02 CFU/mL) and highest bond strength (18.76 ± 1.45 MPa). The photoactivated RB-doped 2 wt% TiO2NPs in adhesive demonstrated promising enhancements in both μTBS and antibacterial efficacy against S.mutans. However, it is noteworthy that this modification led to a decrease in the DC of the adhesive. RESEARCH HIGHLIGHTS: Unmodified ERA-treated samples unveiled the highest bacterial survival and the lowest μTBS. Photoactivated RB-doped 5 wt% TiO2NPs adhesive displayed the lowest S.mutans survival rate and highest bond strength. DC decreased with an increase in concentration of TiO2.

Gender Inequality is negatively associated with academic achievement for both boys and girls

To examine the role of inequality in academic achievement, we analyse a cross-national dataset including data from three cycles from 2012 to 2018 from the PISA, an international assessment of 15-year-old students’ math, reading, and science performance. The Gini coefficient and gender inequality index (GII) were used as metrics for a country’s economic inequality and gender inequality, respectively. The results show that gender inequality has a negative association with academic achievement for both boys and girls. Moreover, gender inequality has a stronger association with academic achievement than does economic inequality. We also find that gender inequality in reproductive health may contribute substantially to the association between gender inequality and academic achievement. Despite substantial advances in gender equality worldwide, multisectoral and multilevel approaches from the community to the country level are needed to ensure substantial long-term reductions in economic, gender, and educational inequalities.

The impact of national culture in predicting informal learning behaviors

PurposeThis study aims to investigate the impact of Hofstede’s six national cultural dimensions on informal learning behaviors (ILBs) and how they moderate the prediction of these behaviors by workplace interaction (WI), autonomy (WA) and readiness to learn (RtL).Design/methodology/approachCultural scores were extracted from The Culture Factor Group in 2023. Data on ILBs and their antecedents were selected from a Program for the International Assessment of Adult Competencies sample of 59,103 workers – 33 Countries. The authors applied hierarchical linear modeling (HLM) to analyze data.FindingsNone of those cultural dimensions had significant direct relationships with ILBs. The moderations were significant for power distance (ILBs with WA and RtL), individualism (ILBs with WI) and motivation toward achievement and success (ILBs with WA).Research limitations/implicationsThe cultural dimensions were limited to Hofstede’s model, and scores at the country level did not consider individual perceptions of them. The results provide empirical evidence for solid theoretical development on the impact of national culture on informal learning and the development of public policies to promote it.Originality/valueThe authors are unaware of other studies that have quantitatively investigated relationships between ILBs and their antecedents and the cultural dimensions using HLM. Findings from different countries allow for better generalization and may provide directions for research and the expansion of the nomological network on the impact of national culture on ILBs.

A Look at External Political Efficacy and the Role of Digital Skills in the Adults U.S. Population

The ability to effectively use digital technology and problem-solve are critical skills for maintaining democratic health, particularly as civil society and the modern digital landscape continuously evolve. However, information on whether individuals have the critical problem-solving skills to use digital technology and confidently affect change is yet to be further explored. Using data from the 2017 Program for International Assessment of Adult Competencies ( n = 2749), we examined the associations between digital problem-solving skills and the three levels (low, neutral, high) of external political efficacy in the U.S. adult population. We used multinomial logistic regression and found a positive association between digital problem-solving skills and external political efficacy, while explanations for the three levels of efficacy are nuanced. Continuous development of digital problem-solving skills through adult education has implications for political efficacy, and ultimately for the promotion of a variety of civic engagement in the adult life stages.

Searching for a relationship between the elemental composition of archaeological bones and the occurrence of caries.

Although the macroscopic assessment of dental caries and the assessment of bone elemental composition are quite different, efforts can be made to identify commonalities in the assessment of health and nutritional quality. Both indicators are correlated with dietary habits and are dependent on taphonomic processes occurring in the postmortem substrate. However, teeth exhibit structural resilience of their hard tissues to adverse environmental factors. The aim of the study was to establish a correlation between the elemental composition of bones and the presence of carious lesions. The study material consisted of the following skeletal parts: 161 permanent teeth from 36 individuals and bridge fragments of 36 ribs. The presence of caries was assessed visually using a modified International Caries Detection & Assessment System (ICDAS II) scale. The rib samples were subjected to elemental analysis (zinc (Zn), iron (Fe), magnesium (Mg), calcium (Ca), phosphorus (P), strontium (Sr), barium (Ba)) using spectroscopic methods. The odontological and chemical analyses did not reveal any statistically significant relationships between the Ca/P diagenesis index and dental features. Postmortem tooth loss showed a weak correlation with the diagenesis index. Discoloration, cracks and flaking of the dental crown surfaces may be associated with the intensity of Ca/P diagenesis. However, no significant correlation was found between these phenomena. Among other elements, only Zn levels exhibited a correlation with the caries index.

Effect of tablets containing a paraprobiotic strain and the cranberry extract on caries incidence in preschool children: A randomized controlled trial.

Preand probiotics may help restore a dysbiotic oral ecosystem. The first years of life provide a window of opportunity to modulate the composition of the oral microbiota and prevent disease. The aim of the present study was to investigate the effect of a tablet containing inactivated Ligilactobacillus salivarius CECT 5317 and the cranberry extract on the development of caries in cariesactive preschool children. The study employed a randomized, placebo-controlled, double-blind design. Preschool children (N = 73) with at least one active carious lesion were enrolled and randomly assigned to the test group or the placebo group. The intervention period was 3 months. Caries was assessed according to the International Caries Detection and Assessment System (ICDAS) II criteria at baseline and after 9 months, and oral hygiene was evaluated with the simplified oral hygiene index (OHI-S). The salivary counts of Streptococcus mutans and Lactobacillus spp. were determined at baseline, and then after 3 and 9 months through the conventional cultivation on TYCSB and MRS agar, respectively. Sixty children completed the trial (a dropout rate of 19%). The baseline caries prevalence was high in both groups (~71%) and there were no major differences between the groups with regard to background variables. The 9-month incidence of initial carious lesions (ICDAS 1+2) was significantly lower in the test group as compared to the placebo group (p < 0.05). The plaque levels, and the salivary counts of S. mutans and Lactobacillus spp. remained unchanged in both groups throughout the study. A daily intake of a tablet containing a paraprobiotic and the cranberry extract reduced the 9-month incidence of initial non-cavitated carious lesions in caries-active preschool children. The present study is one of the first to show the impact of synbiotics on the development of caries in children.

Reliability of impedance spectroscopy versus digital radiograph and ICDAS-II in occlusal caries detection: a prospective clinical trial

The traditional methods in early caries detection had many limitations. So, this study aimed to evaluate the clinical performance of alternating current impedance spectroscopy ACIST in comparison with digital radiograph and ICDAS-II in detection of occlusal carious lesions. Occlusal surfaces of molar and premolar teeth from 40 adult participants were examined by two observers using three diagnostic methods: (1) international caries detection and assessment system (ICDAS-II) (2) digital radiograph (DR) and (3) Cariescan Pro device (ACIST). Agreement analysis and the difference in sensitivities and specificities were evaluated. The results showed an excellent agreement in the different groups. The difference from the visual tactile against ACIST scoring for enamel caries detection, was statistically significant (p = 0.012) and the agreement was moderate (k = 0.509). For dentinal caries the difference was not statistically significant (p > 0.05) and the agreement was similarly moderate (k < 0.6). The difference from the digital radiograph against ACIST scoring, for enamel caries, digital radiography had significantly higher sensitivity and specificity than ACIST (p < 0.001) while for dentinal caries detection and overall, ACIST had higher sensitivity and digital radiography had higher specificity and the difference was statistically significant (p < 0.001). Visual-tactile examination is a considered as feasible and valid technique for occlusal caries detection, digital radiography is superior to ACIST in diagnosing enamel caries, but it could underestimate the caries depth, ACIST is a reliable tool for detecting occlusal caries in dentin.

What can impact on the presence of carious lesions in first permanent molars? Revisiting the association between MIH and caries.

Assess whether the independent variables (IV) such as number of MIH-affected molars, MIH severity, past caries experience, visible plaque index (VPI), gingival bleeding index (GBI), age, and gender affect the presence of caries lesion (DMF_s) in first permanent molars, considering or not atypical restoration in MIH-affected molars as a previous caries lesion. A sample of 476 schoolchildren, aged 6-10years, were evaluated for MIH and caries diagnosis, using the Severity Scoring System (MIH-SSS) and the International Caries Detection and Assessment System (ICDAS), respectively. From the ICDAS, the DF-s/ D-s and df-s were calculated. The Zero-inflated Negative Binomial Regression was used to evaluate the impact of the IV on the dependent variable, considering or not the restorative component in MIH-affected molars. When the presence of caries was evaluated with the restorative component, age, MIH severity and past caries experience had a significant impact on the dependent variable (R2 = 0.176). Without the restorative component in MIH-affected molars, only age and past caries experience were statistically significant (R2 = 0.167). Since in the case of MIH teeth restoration may be attributed to post-eruptive breakdown rather than previous caries lesions, in the present study MIH did not influence the presence of caries lesions in the MIH-affected molars showing that restoration is not an adequate parameter for measuring the historical occurrence of caries. The first permanent molars may not necessarily be at an increased risk of caries due to MIH if the etiological factors for caries development are effectively managed.

Evaluation of Oral Health Status and Treatment Needs of Children with Congenital and Acquired Heart Disease.

Objective: To evaluate the oral health status and treatment needs of children with congenital and acquired heart disease. Methods: This descriptive study included 301 children aged 5-14 from June 2022 to June 2023. Heart conditions were classified by congenital/acquired status and severity. The children's sociodemographic characteristics, medical and dental history, tooth brushing habits, and non-nutritional habits (bruxism, nail-biting, thumb-sucking, etc.) were evaluated. Oral health assessments including caries, oral hygiene, enamel defects, and dental treatment needs-related indices were recorded. Results: The mean age was 8.95 ± 2.91 years, and 271 (90%) of the children had congenital heart disease. The children with moderate and severe heart disease had significantly higher decayed/missing/filled surfaces (dmfs) (p = 0.038) and pulp exposure (p = 0.015) compared to the children with mild heart disease. According to the International Caries Detection and Assessment System II (ICDAS II) index, which included initial caries lesions, there were no caries-free children and 75.7% had extensive caries. The mean plaque index and gingival index were found to be 1.18 ± 0.38 and 0.69 ± 0.53, respectively. Enamel defects were observed in 15.9%. The Treatment Needs Index (TNI) was 85.8% for the primary teeth and 88.9% for the permanent teeth. The Care Index (CI) was 12.4% for the primary teeth and 10.8% for the permanent teeth. Conclusions: Children with congenital and acquired heart disease exhibit a high prevalence of untreated dental caries, gingivitis, and plaque accumulation, with a high need for dental treatments. Dentists should prioritize addressing these issues to prevent the risk of infective endocarditis (IE) and improve oral health outcomes in this population.
