The effect of socio-economic status on children's dental health.

The aim of the present study was to record the oral health status of children from different socioeconomic backgrounds and correlate these findings with parent-associated factors. It comprised a cross-sectional study of healthy children, aged 6-12 years, attending either the Reception and Solidarity Center of the Municipality of Athens or the Postgraduate Paediatric Dentistry Department (NKUA) for dental care. Data regarding the demographics of both parents-guardians, as well as the children, and oral hygiene and dietary habits were collected through a structured questionnaire. This was followed by a thorough clinical examination evaluating oral hygiene status, gingival inflammation and caries experience. Analysis was based on the socioeconomic status (SES) of the parents which was according to the family income. Families with a monthly income of <1400 euros were considered as being of a low SES and families with incomes of >1400 euros as medium. Data were presented in frequency tables and significance of calculated differences was tested using chi-square and Fisher's exact tests. Multivariate regression analysis was used to detect possible risk factors for development of poor dental health. The sample consisted of 216 children (146 from a low and 70 from a medium SES) with a mean chronological age of 9.19 years. Parents from low SES were younger, of lower education, had lived abroad most of their lives and were unemployed or worked in the private sector. Children from low SES backgrounds reported infrequent dental visits, consumed more meals and had more sugary snacks. This was reflected in their worse dental health with significantly higher values for oral hygiene and caries indices. Despite the above differences, none of the parent-associated factors were significantly correlated to worse dental health. In conclusion, SES of parents is reflected in the oral health of children, although it is not a significant predictor of dental health.

Black stain and dental caries in primary dentition of preschool children in Qingdao, China.

Black stain (BS) and caries are common oral issues in children worldwide. This study aimed to reveal the prevalence of BS and caries in primary dentition of children in Qingdao, China and evaluate the potential association between them. A total of 672 preschool children aged 3-5 years old from 12 kindergartens in Qingdao, northern China were enrolled in the study. The prevalences of BS and caries were counted, and their distributions across different ages and genders were analyzed. The potential protective role of BS (independent variable) on caries (dependent variable) was analyzed via binary logistic regression analysis. BS was observed in 103 children (15.33%), including 3 severe- (0.45%), 28 moderate- (4.17%), and 72 mild (10.71%) forms. Caries was observed in 374 children (55.65%) and it was positively associated with age. Notably, the prevalence of caries was lower in children with BS than in those without BS (42.72% vs. 58.00%, respectively). Children with BS were less likely to suffer from caries than those without BS. BS in mild or moderate/severe forms was associated with a low risk of caries. In summary, the prevalence of BS in primary dentition in Qingdao, China is at a relatively high level worldwide. BS is a protective factor for caries in primary dentition.

The influence factors on pit and fissure sealing behavior of 12-year-old children: a cross-sectional study in Zhejiang, China.

BACKGROUND: In the 21st century, dental caries remains a global burden, particularly severely affecting the growth and quality of life of 12-year-old children. Fortunately, pit and fissure sealing (PFS) procedures can effectively prevent molars from caries. Hence, this study focused on the relationship between PFS and oral epidemiological factors in 12-year-old children. METHODS: A cross-sectional survey was conducted in 12-year-old children from 11 cities in Zhejiang Province. Their dental conditions were collected through questionnaires, as well as basic information such as relevant family information, oral health knowledge and behavior. Then, logistic regression analysis was used to identify the influencing factors associated with PFS. RESULTS: A total of 1204 children were included, with 252 in the PFS group and 952 in the non-PFS group. There were significant differences between the two groups in terms of decayed, missing and filled teeth (DMFT) score, first permanent molar DMFT score, residential area, educational level of parents, tooth-brushing frequency, use of dental floss, oral examination in a medical institution, having taken courses on oral health care, as well as having knowledge that tooth brushing could effectively prevent gingival inflammation, PFS could protect teeth, and oral disease may affect general health. According to further logistic regression analysis, the independent factors influencing PFS included use of dental floss [odds ratios (OR) = 1.672, 95% confidence intervals (CI) = 1.235-2.263, P = 0.001], having taken courses on oral health care (OR = 0.713, 95% CI = 0.515-0.988, P = 0.042), having knowledge that tooth brushing is effective in preventing gingival inflammation (OR = 0.627, 95% CI = 0.389-0.987, P = 0.044) and having knowledge that PFS can protect teeth (OR = 0.589, 95% CI = 0.438-0.791, P < 0.001). CONCLUSION: PFS can reduce the mean DMFT score of 12-year-old children. Independent influencing factors of PFS consist of use of dental floss, having taken courses on oral health care, oral health behavior and knowledge level.

Unmasking caries risk: a multi-regional study in Saudi Arabia.

BACKGROUND: Dental caries are common and troublesome and may affect individuals' health conditions. It is crucial to comprehend the caries experience for prevention, management, and enhancing oral health. Techniques such as CAMBRA can help assess an individual's risk factors for caries lesions. This study aims to assess the caries risk in five distinct regions of Saudi Arabia, utilizing the CAMBRA methodology. METHODS: This multiregional cross-sectional study was conducted at university dental clinics across the five regions of Saudi Arabia, using a Caries Management by Risk Assessment (CAMBRA) tool. This study used binary logistic regression analysis, the Pearson Chi-square test, and descriptive analysis as statistical methods. RESULTS: A total of 551 respondents participated in the study, with 59.7% being male and 40.3% being female. The age group with the highest proportion was 20-29, making up 31.6% of the participants. All participants exhibited at least one caries lesion (100%), with white spots (66.4%) and enamel lesions (56.1%) being the most prevalent. The moderate-risk category encompassed the largest proportion of participants, accounting for 60% of the total. High caries risk had a significant association with age group (P < 0.001), education (P < 0.001), profession (P < 0.001), and socio-economic status (P < 0.001). Furthermore, only age and socio-economic status showed a significant relationship with high caries risk in the multiple logistic regression. CONCLUSION: The CAMBRA tool indicates a high prevalence of moderate risk across the five regions of Saudi Arabia, identifying age and socio-economic status as significant predictors of caries risk.

Association between high birth weight and dental caries at 4-5 years of age: a birth-cohort study.

OBJECTIVE: Early childhood caries has become a globally crucial oral health problem over the decades. Most studies have discussed the association between low birth weight and early childhood caries; however, studies focusing on high birth weight have been relatively limited. This study aimed to assess the impact of high birth weight on the incidence and severity of dental caries in 4-5-year-old children. SUBJECTS AND METHODS: Study subjects included 491 children from a birth cohort study at 4-5 years of age. Data on dental caries, prenatal and perinatal factors, and socio-demographic determinants were recorded. Logistic regression models adjusted for potential confounders were performed to analyze the data. Two-sided P-value < 0.05 was considered statistically significant. RESULTS: Of the 491 children, the prevalence of dental caries was 48.7%. High birth weight (≥ 4,000 g) was significantly associated with increased incidence of dental caries (OR, 2.000; CI 95% 1.062-3.765), and the relatively enhanced risk OR was further increased in subjects experiencing caries (dmft ≥ 3) (OR, 2.437; CI 95% 1.306-4.549) compared with the normal birth weight (2,500-3,999 g). CONCLUSIONS: High birth weight is a risk factor for early childhood caries. Particular attention should be paid to children with birth weight more than or equal to 4,000 g.

Relationship of dietary nutrients with early childhood caries and caries activity among children aged 3-5 years-a cross-sectional study.

BACKGROUND: Early childhood caries (ECC) is a challenge for pediatric dentists all over the world, and dietary factor is an important factor affecting the occurrence of ECC. Currently, there is limited research on the impact of dietary nutrient intake from Chinese diets on ECC. The purpose of this study is to explore the correlation of dietary nutrients intake with ECC and caries activity (CA) among children aged 3-5 years, and to provide dietary guidance to slow down the occurrence and development of ECC. METHODS: A cross-sectional study was conducted in 2022. A total of 155 children were divided into three groups: caries-free group, ECC group and Severe early childhood caries (SECC) group according to the caries statues. And according to the caries activity test (CAT) value, they were also divided into three group: low CA group (L-CA), middle CA group (M-CA) and high CA group (H-CA). The 24-hour dietary intake information was collected by mobile phone application (APP). The intake of children's daily dietary nutrients were calculated referring to "China Food Composition Tables". RESULTS: In this study, 17, 39,and 99 children were diagnosed with caries-free, ECC, and SECC. There were 33, 36, and 86 children diagnosed with L-CA, M-CA, and H-CA. The risk of ECC was increased with the intake of cholesterol(OR = 1.005) and magnesium (OR = 1.026) and decreased with the intake of iron (OR = 0.770). The risk of SECC was increased with the intake of cholesterol (OR = 1.003). The risk of high CA was increased with the intake of cholesterol (OR = 1.002). The combined application of dietary total calories, carbohydrate, cholesterol, sodium, magnesium and selenium in the diagnosis of ECC had an area under ROC curve of 0.741. CONCLUSIONS: The increased dietary cholesterol intake may be a common risk factor for ECC and high CA in children aged 3-5. The combined application of dietary intake of total calories, carbohydrate, cholesterol, sodium, magnesium and selenium has a higher predictive value for the occurrence of ECC.

Epidemiology of dental caries in internally displaced children during wartime in Ukraine.

OBJECTIVE: Aim: To conduct a comprehensive analysis of the oral health status of this vulnerable population in order to collect objective data that will contribute to the development of effective strategies for maintaining and improving oral health in wartime conditions. PATIENTS AND METHODS: Material and Methods: This epidemiological study was carried out within the initial 6 months of the full-scale invasion of the country. The oral health indices of 1050 internally displaced children, aged 3 to 17 years, seeking dental care at the Municipal Children Dental Clinic in Poltava, were analyzed. RESULTS: Results: The total sample comprised 620 children aged 6-11 years (mean = 8.5, SD = 0.76), with a gender distribution of 52% boys and 48% girls. The participants were divided into three age groups: Group I (6-7 years), Group II (8-9 years), and Group III (10-11 years). The average prevalence of dental caries, as measured by the dmft + DMFT index, was 76.5%, with prevalence increasing with age. Specifically, the prevalence of dental caries based on the dmft index was lower in children of Group III (66.6%) compared to Group I (79.49%). CONCLUSION: Conclusions: The analysis of the oral status among internally displaced children aged 6-11 years revealed higher dental caries prevalence and intensity compared to local children. Notably, children aged 6-7 years showed a high rate of caries in temporary teeth.

Impact of dental caries and Self-perceived oral health on daily lives of children and mothers in rural Egypt: a household survey.

BACKGROUND: The present study assessed the impact of oral health on the daily lives of children and mothers living in a rural area in Northwestern Egypt. METHODS: A cross-sectional household survey including children between 6 and 12 years old and their mothers was conducted in rural Egypt, 2019-2020. Data were collected using clinical examination and interview-based questionnaires of children and mothers. Three binary logistic regression models were used to assess the relationship between the dependent variables (oral health impact (yes, no) on avoiding smiling, chewing problems, and missing school (children) and avoiding social events (mothers)), and the explanatory variables: oral health (clinically-assessed caries experience and self-reported oral health) controlling for sociodemographic profile (child age and sex, mother's education), daily toothbrushing and village of residence. RESULTS: A total of 211 households with 355 children and 211 mothers were included (91.5% response rate). About 54% of the children were girls, mean (SD) age = 8.7 (2.05) years and 82.3% did not brush their teeth daily. Mother's mean (SD) age was 31.70 (5.45) years. Because of dental problems, 31.3% of children reported chewing difficulties, 31% avoided smiling compared to 76.3% and 43.6% of mothers. Also, 30.4% of children missed school and 76.8% of mothers reported reduced participation in social activities. In children, the number of decayed anterior teeth was associated with significantly higher odds of avoiding smiling (AOR = 1.22, 95%CI: 1.03, 1.44). In mothers, a greater number of posterior missing teeth was associated with significantly higher odds of chewing difficulties (AOR = 1.21, 95%CI: 1.01, 1.45), and a greater number of all missing teeth was associated with significantly higher odds of reduced participation in social events (AOR = 1.30, 95%CI: 1.30, 1.57). Good/ very good reported oral health in children and mothers was associated with lower odds of avoiding smiling and chewing problems (p < 0.05). CONCLUSION: Decayed anterior teeth in children have a negative impact on smiling whereas missing teeth in mothers affect the ability to chew food and socialize. The psychological, functional, and social impacts of caries in this rural setting needs to be mitigated by improving oral health literacy and access to care.

An investigation of the association between parenting style and child's dental caries: a cross-sectional study.

To investigate the association between parenting style and child's dental caries. Parents presenting with their children to the Department of Pediatric Dentistry at Tufts University School of Dental Medicine for an initial exam or re-care appointment completed a demographic survey and the parenting styles and dimensions questionnaire. Recruitment of subjects started in May 2019 and ended in February of 2020. Child's decayed, missing, and filled teeth (dmft) index, diet score, sex, and age were recorded, as were parent's race, education level, and form of payment. Adjustment for confounders was done using multivariable negative binomial regression. The sample size was 210 parent/child dyads. In the multivariable analysis, parenting style and child's dmft were not significantly associated (p > 0.05). Parents with an education level less than high school (p = 0.02) and at the high school graduate level (p = 0.008) were significantly associated with children who had higher dmft, compared to parents with a college degree or higher. Children with excellent diet scores had significantly lower dmft than children with a diet score in the "needs improvement" category (p = 0.003). There was no significant evidence that parenting style is associated with child's dental caries. Parent's education level and child's diet score were significantly associated with child's dmft, less than high school (p = 0.02) and at the level of high school graduate (p = 0.008). Pediatric dental professionals should be aware of these risk indicators.

PREVALENCE OF CARIES PATTERNS IN THE 21ST CENTURY PRESCHOOL CHILDREN: A SYSTEMATIC REVIEW AND META-ANALYSIS.

OBJECTIVE: This systematic review aimed to describe and evaluate the caries patterns among the 21st century preschool children globally. METHOD: Six electronic databases (Pubmed, Embase, Medline, Web of Science, EBSCOhost, and Scopus) were searched using predetermined terms. Dual independent screening of all retrieved abstracts was performed to identify studies conducted after year 2000 and the caries pattern among preschool children was investigated. Data regarding the prevalence of caries by tooth type and surface were extracted. Meta-analyses, subgroup analyses and meta-regression were carried out with the statistics software Stata using the random-effects model. RESULTS: A total of 2642 records were screened, and 43 observational studies were finally included. Cavitated caries lesions were commonly found in the maxillary incisors and molars in both arches among preschool children. The highest caries prevalence was found in the maxillary central incisors (29.1%, 95%CI: 25.5%-32.7%) and the mandibular second molars (28.5%, 95%CI: 24.7%-32.3%), while the mandibular lateral incisors had the lowest prevalence (1.7%, 95%CI: 1.5%-2.0%). Occlusal surfaces of the mandibular molars were the most frequently affected by caries, whereas caries hardly affected the lingual surfaces of lower anterior teeth. Caries pattern on the left and right sides was symmetrical. The overall caries prevalence was significantly higher in the maxillary teeth. Caries prevalence was higher in the older children, whereas the caries pattern was not significantly different among children from countries with different human and economic development levels. CONCLUSION: Cavitated carious lesions were more commonly observed in the maxillary incisors and molars in both arches. The prevalence of caries varies significantly with child's age and primary tooth type. However, preschool children exhibit a similar pattern of caries, regardless of the time, socioeconomic status or geographical location.

Utilization of Dental Care and Oral Health Outcomes in the United States: Results from the National Health and Nutrition Examination Survey (2017-2020).

PURPOSE: This analysis aims to evaluate the association between the time since and reason for a patient's last dental appointment across clinical oral health outcomes. MATERIALS AND METHODS: We used data from the 2017-2020 National Health and Nutrition Examination Survey (NHANES), a cross-sectional, nationally-representative survey of noninstitutionalized US adults. The predictors were the time since and the reason for the last dental appointment (routine vs. urgent). We examined the presence and number of missing teeth and teeth with untreated coronal and root caries. Multivariable regression models with interaction were used to assess the association between the time since the last dental appointment and clinical oral health outcomes among routine and urgent users separately. RESULTS: Two-thirds of the US population had a dental appointment within a year, while nearly 44 million individuals did not visit a dentist for the last three years. The odds of having teeth with untreated coronal or root caries increased with the length of time since the last appointment, and urgent users had worse dental outcomes compared to routine users. Compared to those who had a dental appointment within a year, individuals who had their last dental appointment more than 3 years ago had 2.94 times the average number of teeth with untreated caries among routine users (95%CI=2.39, 3.62) and 1.60 times the average among urgent users (95%CI=1.05, 2.43). CONCLUSIONS: Recent, routine dental appointments are associated with improved oral health outcomes. The outcomes reiterate how social determinants of health impact access to oral health care and oral health outcomes.

Association between the number of existing teeth and maintenance dialysis therapy: A cross-sectional study of adult male dentists.

Dental caries and periodontal disease are typical oral diseases frequently observed in patients with renal diseases. Tooth loss is an outcome of dental caries and periodontal disease, and the number of existing teeth is an indicator of oral health status. However, the association between the number of existing teeth and end-stage kidney disease (ESKD) has not been investigated in detail. This study aimed to investigate the association between oral health status, expressed by the number of existing teeth, and ESKD. We analyzed data from the second survey of the Longitudinal Evaluation of Multi-phasic, Odontological, and Nutritional Associations in Dentists, a cohort study conducted among members of the Japan Dental Association. From August 2016 to July 2017, self-administered questionnaires were mailed to 16,128 male dentists and 8,722 responded. Among them, 7,479 men with complete data on age, number of existing teeth, and ESKD were included in the analysis. Multivariate logistic regression analysis was conducted, with ESKD as the dependent variable and the number of existing teeth (≥23 teeth and <23 teeth) as the independent variable. Subgroup analysis by age (<65 years and ≥65 years) was also conducted. The <23 teeth group had a significantly higher rate of ESKD than did the ≥23 teeth group. After adjusting for age, body mass index, smoking habits, hypertension, and diabetes mellitus, there was no significant association between having <23 teeth and ESKD in all participants. However, the subgroup analysis revealed a significant association after adjustment for covariates in participants aged <65 years but not in those aged ≥65 years. In conclusion, having <23 teeth was associated with the risk of requiring maintenance dialysis therapy among Japanese men aged <65 years. Therefore, tooth loss may be associated with renal function decline.

[Dental caries in schools in the city of N'Djamena in Chad: Epidemiological aspects and oral habits in pupils aged from 6 to 12 years]. / Carie dentaire en milieu scolaire dans la ville de N'Djamena au Tchad : aspects épidémiologiques et habitudes bucco-dentaires chez des élèves âgés de 6 à 12 ans.

Background: Dental caries is a global disease that can have disabling effects. In Africa, its prevalence in schools is very variable, due to the great variability of food habits and oral hygiene. This study aimed to assess the prevalence of dental caries, associated factors, and to research oral pathologies associated with that dental decay in one circumscription of the city of N'Djamena. Material and methods: This was a cross-sectional study conducted in 3 schools in the 7th borough of the city of N'Djamena. A total of 360 pupils aged between 6 and 12 years were recruited between October 2021 and September 2022. Each participant underwent to an oral examination which consisted in looking carefully at the pupil's face (cheeks, lips) to note any deformities or possible facial asymmetry, and to check for any sensation of pain in any part of the face. In another hand, the oral examination aimed to look for any decay on all the teeth and determine the category and class of it. Finally, the personal data (age, sex, class, parents' occupations) of each participant and the results of his oral examination were collected into a database and analyzed. Results: A total of 185 pupils had at least one decayed tooth, giving a prevalence rate of 51.4%. Among them, 45% had at least 2 decayed teeth. The school attended and snacking between meals were significantly associated with the presence of caries (p<0.05). Teeth 36 (lower left first molar) and 46 (lower right first molar) were the most often affected by caries (21% and 22% respectively). The mixt DMF index was 0.6 and the overall frequency of decayed teeth was 51.9%. According to Black's classification, class II caries was the most prevalent (48%), while according to Baume's classification, category II was the most prevalent (54%). The time of brushing, the material and the type of product used significantly influenced the appearance of caries (p<0.05). Participants with dental dyschromia had more tooth decay. Conclusion: Caries was prevalent in the targeted schools and represented a real problem for pupils. Implementing an oral health policy based on preventive dentistry by raising awareness among children and their parents would contribute to the proper education of pupils.

The association between dental caries and serum crp in the us adult population: evidence from NHANES 2015-2018.

BACKGROUND: Dental caries remains one of the most prevalent diseases worldwide, affecting 29.4% of the global population. Despite numerous efforts to diagnose, predict, and prevent dental caries, the incidence continues to rise. Salivary biomarkers provide a non-invasive means for early detection of various oral conditions. C-reactive protein (CRP) is a key marker, elevated in both oral and general inflammatory conditions such as diabetes, periodontitis and oral squamous cell carcinoma. Considering the emerging connection between oral and systemic health, it is worth exploring the various factors associated with this widespread disease. This study investigates the association between CRP levels and dental caries in the United States population, utilizing data from the National Health and Nutrition Examination Survey (NHANES). METHODS: The study analyzed data from the 2015-2018 NHANES cycles, focusing on a nationally representative sample of individuals aged 30 years and above. Weighted multivariable negative binomial and logistic regression analyses were employed to explore the relationship between dental caries and CRP levels, adjusting for age, gender, race, education level, diabetes status, and gum disease. RESULTS: The results of the negative binomial regression analysis demonstrated a positive association between higher CRP levels and an increased mean number of dental caries (Adjusted Mean Ratio [AMR] = 1.7; 95% CI: 1.3 - 2; P: < 0.001). The logistic regression analysis showed that individuals with higher CRP levels have a 50% increase in the odds of developing dental caries (AOR: 1.5, CI: 1.2 - 1.9; P: < 0.01). CONCLUSION: The results of this cross-sectional study of the U.S. population highlight the positive association between high CRP levels and increased dental caries. These findings contribute to the growing body of evidence supporting the integration of oral and systemic health care. Further research is necessary to deepen our understanding of the mechanistic relationship between CRP levels and dental caries.

Cross-sectional survey and analysis of factors influencing the prevalence of dental caries among older individuals aged 65-74 in Guangdong Province in 2021.

BACKGROUND: The prevalence of oral diseases is subject to change over time. In 2021, Guangdong Province conducted its fourth survey assessing the oral health status of individuals aged 65-74. MATERIALS AND METHODS: Evaluation criteria and potential influencing factors were identified. A sample of residents aged 65-74 from 13 designated monitoring sites in Guangdong Province was randomly selected for the study. Spearman correlation analysis was employed to investigate the clinical correlation between influencing factors and evaluation criteria. Negative binomial and zero-inflated negative binomial regression models were utilized to examine the factors influencing caries prevalence. In contrast, logistic regression was employed to identify the risk factors for caries occurrence. A p-value of ≤0.05 was considered statistically significant. RESULTS: The prevalence of caries rate of crowns, roots, and teeth were 76.36%, 52.25%, and 79.2%, respectively. Individuals with periodontal pockets exhibited a significantly higher risk of root caries. The presence of dental calculus significantly exacerbated the occurrence of crown, root, and dental caries, and increased the risk of crown and dental caries. Consuming sweet foods once or more a week notably increased the average root decayed score (D of roots), the prevalence rate of root caries, and the D score of the Decayed, Missing, and Filled teeth [DMFT] index in individuals already afflicted with this condition. Similarly, the consumption of sweetened drinks significantly elevated the risk of crown and root caries, exacerbating overall caries progression. Frequencies of manual toothbrush and toothpick cleaning showed a negative correlation with average tooth missing score (MT). In contrast, the frequency of manual/electric toothbrush and toothpick cleaning was negatively correlated with the DMFT index. Engaging in dental diagnosis and treatment behaviors significantly increased the number of filled crowns (F), MT, and DMFT scores while reducing the prevalence of dental caries. CONCLUSIONS: In Guangdong Province, caries prevalence among older individuals aged 65-74 remains substantial. Relevant professionals and institutions must provide comprehensive guidance and assistance to the older population, emphasizing the importance of reducing the consumption of sweets and sweetened beverages, adopting correct tooth brushing techniques and frequency (at least twice daily), timely treatment of periodontal diseases, conducting regular epidemiological caries surveys, and addressing economic barriers to accessing caries diagnosis and treatment services.

Exploring the state and influential factors of dental caries in preschool children aged 3-6 years in Xingtai City.

OBJECTIVE: To explore the main factors affecting early dental caries among preschool children aged 3-6 years in Xingtai City to formulate effective preventive measures. METHODS: A cross-sectional study was conducted on 570 preschool children aged 3-6 years in Xingtai City through questionnaire surveys and oral examinations to understand their dental caries situation. Multifactorial logistic regression analysis was used to analyse the main influencing factors for the occurrence of dental caries in preschool children. RESULTS: Univariate analysis showed statistically significant differences in age (χ2 = 2.636, p = 0.008), father's education level (χ2 = 4.207, p < 0.001), mother's education level (χ2 = 4.217, p < 0.001), daily tooth brushing frequency (χ2 = 3.160, p = 0.002), age of starting tooth brushing (χ2 = 8.756, p < 0.001), mouth rinsing after meals (χ2 = 89.401, p < 0.001), Streptococcus mutans positivity (χ2 = 133.503, p < 0.001), non-sweet snack consumption frequency (χ2 = 5.962, p < 0.001), snack flavour preference (χ2 = 116.119, p < 0.001), use of fluoridated toothpaste (χ2 = 75.639, p < 0.001), regular oral examinations (χ2 = 98.711, p < 0.001), sugary drink consumption frequency (χ2 = 10.370, p < 0.001) and sweet food consumption frequency (χ2 = 9.261, p < 0.001) between the caries and non-caries groups. Multifactorial analysis revealed that older age (odds ratio [OR] = 5.342, 95% confidence interval [CI]: 1.434-6.631), later initiation of tooth brushing (OR = 3.244, 95% CI: 2.413-5.424), S. mutans positivity (OR = 5.357, 95% CI: 4.529-8.563), high snack consumption frequency (OR = 3.452, 95% CI: 2.634-5.442), high sugary drink consumption frequency (OR = 4.414, 95% CI: 2.534-6.451) and high sweet food consumption frequency (OR = 4.531, 95% CI: 3.421-6.354) were risk factors for dental caries. Higher father's educational level (OR = 0.724, 95% CI: 0.564-0.891), higher mother's educational level (OR = 0.641, 95% CI: 0.601-0.813), high daily tooth brushing frequency (OR = 0.572, 95% CI: 0.423-0.864), mouth rinsing after meals (OR = 0.743, 95% CI: 0.643-0.813), use of fluoridated toothpaste (OR = 0.657, 95% CI: 0.553-0.931) and regular oral examinations (OR = 0.443, 95% CI: 0.352-0.747) were protective factors against dental caries (all p < 0.05). CONCLUSION: Multiple factors result in early dental caries in preschool children aged 3-6 years; however, the most influential factors are older age and high snack consumption, as well as high sugary and sweet food/drink consumption.

[Comparative assessment of the intensity of caries among dental patients of older age groups in need of removable prosthetics, registered by a phthisiatician and their perception of an artificial ageist situation.]

Improving the quality of life of older age groups is an urgent problem of medicine, including its components: gerontology, phthisiology and dentistry. The objectives of the study are: to establish the importance of tuberculosis as an infection that causes the intensity of caries among patients of older age groups; assessment using the Palmore scale of gerontological ageism «The ageism survey¼ and patients' perception of an artificial situation of age inequality. The study involved elderly (n=122) and senile (n=121) persons with partial secondary adentia who needed removable dentures. The control groups of older people included patients who denied being under the supervision of a phthisiologist, and the study groups confirmed this. To solve the first problem, a comparative assessment of the values of the components of the CPI index in the control and study groups was carried out. To solve the second problem, an artificial situation of age inequality was simulated in the process of dental admission. The results of its effects were evaluated based on the response of patients to questions № 9, 10 of the Palmor scale. The absence of a difference in the values of K and N components between the control and study groups indicates the absence of a significant effect of mycobacteria on the development of caries. The large values of component Y in the studied groups may indicate the detrimental effect of mycobacteria on periodontal disease. The absence of an increase in the intensity and stability of the perception of age inequality among patients who are under the influence of an artificially created situation proves the great effectiveness of background age inequality. At the same time, it is impossible to exclude the low sensitivity of the Palmor scale in the process of diagnosing age inequality in Russian society.

Decomposition of economic inequalities in dental caries among Iranian schoolchildren.

INTRODUCTION: Monitoring social inequalities in dental caries is crucial for establishing priorities in oral health systems. This study aimed to assess economic inequalities in dental caries and its contributing factors among Iranian schoolchildren. METHODS: Data were obtained from the first phase of the Shahroud Schoolchildren Eye Cohort Study in 2015. A total of 4992 children aged 6-12 years old were included in the analysis. Dental examinations were conducted following the diagnostic methods and standards of the Oral Health Examination Survey, as recommended by the World Health Organization. The concentration index (C) was utilized to assess economic inequalities in dental caries. Additionally, the decomposition of C was employed to explain the determinants of the measured inequalities. RESULTS: In total, 71.4% of the schoolchildren had dental caries in primary dentition (dft≥1), and 41.6% of the schoolchildren had dental caries in permanent dentition (DMFT≥1). The Cs of dft≥1, primary decayed teeth (pdt≥1), and permanent missing teeth (PMT≥1) were -0.136 (95% CI: -0.167, -0.104), -0.164 (95% CI: -0.194, -0.134), and -0.208 (95% CI: -0.262, -0.153), respectively, which indicates their more concentration among low-economic children. Conversely, pft≥1 and PFT≥1 had Cs of 0.327 (95% CI: 0.292, 0.361) and 0.218 (95% CI: 0.179, 0.256), showing more concentration among high-economic children. Basic health insurance coverage and age were the main contributors that explained 28.6% and 19.2% of the economic inequality in dft≥1, and 25.7% and 16.6% of the pdt≥1 inequality, respectively. Economic status, residence in rural areas, mother education, father education, and age were the main contributors to the measured inequality in pft≥1 by 80.5% and 26.5%, 21.9%, 22%, and -18.3%, respectively. Economic status, having a housekeeper mother, residence in rural areas, having basic health insurance coverage, mother education, and father education positively contributed to the measured inequality in PMT≥1 by 45.4%, 42.4%, 37.8%, 35.1%, 21.3%, and 15.2%, respectively, while age had a negative contribution of -19.3%. For PFT≥1, economic status, age, and father education accounted for 76%, 25.4%, and 20.3% of the measured inequality, respectively. CONCLUSION: Pro-rich economic inequalities were observed in children's primary and permanent teeth caries. Thus, government interventions to reduce these inequalities should aim to expand the coverage of basic and supplementary health insurance in line with increasing the coverage of dental health costs in these plans, training and providing access to required dental health services for low-socioeconomic children, including the poor, rural, and those who have low-educated parents and a housekeeper mother, especially at younger ages.

Oral hygiene status and vascular aging in schoolchildren and their mothers.

BACKGROUND: Poor oral hygiene, generally manifesting as dental caries, gingivitis, or periodontitis, is a common chronic condition among both children and adults worldwide and has been reportedly associated with hypertension and arterial stiffness mainly in adult patients. However, these associations have not been well-studied in children and adults in the general population. Therefore, we conducted this cross-sectional study to clarify the associations between oral hygiene indices and high blood pressure (BP)/hypertension and arterial stiffness as assessed by the cardio-ankle vascular index (CAVI) in children along with their mothers. The association between maternal oral hygiene and high BP in children was also examined based on the hypothesis that maternal awareness of oral hygiene is related to their children's oral hygiene. METHODS: This study was conducted as an Adjunct Study of the Aichi Regional Sub-Cohort of the Japan Environment and Children's Study. Participating children (n = 220, 85-104 months old) and their mothers (n = 217, 29-52 years old) underwent dental/intra-oral examination and BP and CAVI assessment. High BP in children and hypertension in mothers were diagnosed according to corresponding American guidelines. Logistic regression analysis or analysis of covariance was used to examine the associations of poor oral hygiene indices with BP and CAVI. RESULTS: Maternal dental caries ≥1 was associated with their hypertension (adjusted odds ratio [aOR]: 2.72, 95% confidence interval (CI): 1.12-6.61). Maternal dental plaque ≥1/3 was associated with maternal hypertension and children's high BP (aOR, 95% CI: 4.71, 1.33-16.73 and 5.67, 1.22-25.04, respectively). Maximum pocket depth ≥4 mm was associated with children's high BP (aOR: 6.85, 95% CI: 1.24-38.01). No associations were observed between oral hygiene indices and CAVI in children; however, there was a significant association between dental plaque and CAVI in mothers (F = 5.62, p < 0.01). CONCLUSIONS: The small sample size, especially the case number, made it necessary to refrain from drawing unambiguous conclusion. The hypothesis that warrants further investigation based on the present study results is that poor oral hygiene is associated with high BP in children and hypertension and arterial stiffness in mothers, and maternal oral hygiene is associated with high BP in children.

[Need for prosthodontics of permanent teeth in children aged 8-18 years]. / Nuzhdaemost' v ortopedicheskom lechenii postoyannykh zubov detei 8­18 let.

OBJECTIVE: To reveal need for prosthodontics in permanent teeth in children aged 8-18 years. MATERIALS AND METHODS: The study was performed in Khimki Dental Municipal Clinic. Dental examination and radiological studies were conducted in 97 primary patients aged 8-18 years. Indications for prosthodontics in permanent teeth were occlusal deterioration index more than 40% and crown decay of more than 50% in incisors and canines. Additional features were registered including DMFT index, the presence of extracted teeth and teeth after root canal treatment, as well and teeth with extensive restorations with resins and marginal seal quality. RESULTS: From 97 primary patients (27.8%) children needed prosthodontics in permanent teeth (in average 2.3±2.1 teeth): 1 tooth in 10 children, 2 teeth in 11 children, 3 teeth in 1 child, 4 teeth in 3 children and 4 teeth in 2 children. Mean DMFT was 8.1±4.5 teeth. Six children already had extracted permanent teeth (9 teeth in total). Half of the teeth (49.2%) which needed orthodontic treatment had history of root canal treatment while 46% needed primary or secondary endodontic treatment. Occlusal deterioration index was more than 40% in 41.3% of cases, more than 60% in 49.2% of teeth and more than 80% in 9.52% of teeth. From all the teeth restored with composite resins 41.7% had good marginal seal but 58.3% showed macroscopic signs of marginal leakage. CONCLUSION: Our study shows high percentage of adolescents having need for prosthodontics in permanent teeth and unjustified widening of indications for direct resin restorations in this group of patients.
