Background and Objective: Limited access to health services and low educational levels are factors in the rural population that are associated with the development of oral pathologies. However, the specific risk indicators contributing to erosive tooth wear (ETW) in these populations remain unclear. The objective of this study was to identify risk indicators associated with the prevalence of erosive tooth wear (ETW) in schoolchildren aged 8–12 years from rural and urban areas in the State of Mexico. Methods: A cross-sectional study was carried out in public schools in rural and urban areas. The prevalence of ETW was evaluated using the Basic Erosive Wear Examination (BEWE). The risk indicators studied were gastroesophageal reflux, vomiting, vitamin C, food, beverages, dental hygiene, bruxism, and hyposalivation. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: The prevalence of ETW was higher in the rural area (77.3%) compared to the urban area (51.2%) (p = 0.001). The odds of presenting ETW were more than twice in schoolchildren from rural areas compared to those from urban areas (OR: 2.25, 95% CI: 1.11–3.98). Risk indicators varied between rural and urban populations, with different factors such as the consumption of fresh tomato sauce, orange, tangerine, atole (artisanal corn-based drink), and teeth grinding in the rural area, and lemon, soft drink, fruit juice consumption, and the simplified oral hygiene index in the urban area (p < 0.05). Conclusions: To prevent ETW, strategies offering tailored dietary and hygiene advice should be proposed, considering the specific conditions of each geographic area. [ABSTRACT FROM AUTHOR]

Evaluate the prevalence and severity of caries in permanent teeth and their association with the treatment needs of 8-12-year-old Mexican schoolchildren. The cross-sectional study was conducted on 1139 8-12-year-old schoolchildren attending two public primary schools in State of Mexico. The study used the International Caries Detection and Assessment System (ICDAS) to examine the prevalence of caries and identify treatment needs in schoolchildren. Other variables considered were age, gender, oral hygiene, dental visits ≤6 months, toothbrushing frequency, and the mother's years of education. A logistic regression model was used to identify the association between independent variables and treatment needs. In all analyses, two-tailed p values ≤ 0.05 were considered statistically significant. The prevalence of caries lesions was 82.1% (82.2% boys vs. 81.9% girls) considering all lesion categories (ICDAS 1-6), while the distribution of the severity of caries was 17.9% (ICDAS 0), 13.9% (ICDAS 1-2), 28.3% (ICDAS 3-4) and 39.9% (ICDAS 5-6). The treatment needs index was 77.3%. The logistic regression model showed that the schoolchildren with moderate (ICDAS 3-4) and extensive carious (ICDAS 5-6) lesions were, respectively, 61% Odds Ratio ((OR) = 1.61; p = 0.036) and 77% (OR = 1.77; p = 0.013) more likely to present treatment needs. Other variables, such as poor oral hygiene (OR = 1.52; p = 0.009), the mother's low level of education (OR = 1.53; p = 0.007), and a lack of dental visits (OR = 1.42; p = 0.030) were associated with dental treatment needs. The results obtained show that the 8-12-year-old Mexican schoolchildren presented a high level of treatment needs for moderate and extensive carious lesions (ICDAS 3-6). These findings reiterate the importance of implementing oral health prevention, promotion, and intervention programs to help protect the oral health of school-age children., Competing Interests: The authors declare no conflict of interest., (©2024 The Author(s).

Purpose: To examine the association between educational level and the presence of periodontal disease in adults ages ≥ 50 years in Mexico., Materials and Methods: A cross-sectional study was conducted on 2098 Mexican adults, using data from the annual reports of the Epidemiological Monitoring System for Oral Pathologies from 2019-2022. Data were collected on sociodemographic characteristics such as gender, age, educational level, oral hygiene, and diabetes. Periodontal status was evaluated using the Community Periodontal Index (CPI) and was classified into: CPI &#61; 0 (healthy); CPI &#61; 1 (bleeding on probing); CPI &#61; 2 (calculus); and CPI &#61; 3 or 4 (pocket depth ≥ 4 mm). A multinomial regression model was used to estimate the odds ratio (OR) and the 95% confidence intervals (CI), using periodontal status as the result., Results: 39.9% of subjects presented periodontal pockets of ≥ 4 mm, 20.8% presented calculus, and 12.8% presented bleeding, while only 26.4% were classified as healthy. A low level of education (≤ 9 years) (OR &#61; 4.84; p 0.001), age ≥ 65 years (OR &#61; 1.33; p &#61; 0.025), poor oral hygiene (OR &#61; 6.86; p 0.001), smoking (OR &#61; 1.51; p &#61; 0.025), and diabetes (OR &#61; 1.73; p 0.001) were statistically significantly associated with the presence of periodontal pockets ≥ 4 mm., Conclusions: A low level of education is associated with worse periodontal status in adults aged 50 years or more. These findings reiterate the importance of implementing effective strategies and the incorporation of interventions for improving the access to and quality of services targeted at aging communities.

Aim: To evaluate the association between the frequency and severity of dental fluorosis and Molar Incisor Hypomineralization (MIH) in 8-12-year-old schoolchildren living in an area with a high concentration of fluoride in the drinking water., Methods: The present cross‑sectional study was conducted on Mexican children (n = 573) selected from one community presenting a drinking water fluoride concentration of 1.39 ppm/F. The prevalence of dental fluorosis was ascertained using the Thylstrup and Fejerskov Index (TFI). The presence and severity of MIH was evaluated using the European Academy of Pediatric Dentistry (EAPD) criteria. A multinomial regression model was used to estimate the odds ratio (OR) and the 95% confidence intervals (CI), using the severity of MIH as the result., Results: The prevalence of MIH was 37.7% and, by severity, was 16.1% mild, 14.3% moderate, and 7.3% severe. The prevalence of dental fluorosis in permanent dentition was 70.9% (TFI ≥1) and, by severity, was 29.2% (TFI = 0), 45.6% (TFI 1-3) and 25.3% (TFI ≥4), while 54.5% of subjects were found to have poor oral hygiene. Schoolchildren with fluorosis (TFI ≥4) were 49% less likely [OR = 0.51; p = 0.025] to present mild MIH than children with fluorosis (TFI <4). Similarly, children with fluorosis (TFI ≥4) were 53% [OR = 0.47; p = 0.019] and 62% [OR = 0.38; p = 0.036] less likely to present moderate and severe MIH than children with fluorosis (TFI <4)., Conclusion: An inverse relationship between the presence of fluorosis and MIH was found. The results obtained by the present study may contribute to both the early identification of disorders affecting the enamel and the creation and implementation of long-term oral health prevention, promotion, and intervention programs in the affected population., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Medina Varela et al.

Purpose: To explore the relationship between of self-reported health (SRH) and educational attainment with pastyear dental visits in older adults in México., Materials and Methods: For this cross-sectional study, data were derived from the Mexican Health and Aging Study 2018 (MHAS-2018), which used a nationally-representative sample of older adults (50 years or older) in Mexico (n = 14,085). Variables taken from the MHAS questionnaire included residence (rural/urban), years of education, SRH, multimorbidity, pain severity, and past-year dental visits. A logistic regression model was used to identify the association between the variables and past-year dental visits., Results: While the percentage of past-year dental visits reported was 39.8%, this number declined with age [OR=0.76, p < 0.001], with older adults living in rural areas 34% less likely to report past-year dental visits than older adults living in urban areas. Older adults with no formal education were 73% less likely (OR=0.27; p < 0.001) to report past-year dental visits than older adults ≥10 years education. Older adults with poor SRH were 32% less likely (OR=0.68; p < 0.001) to report past-year dental visits than older adults with good/very good/excellent SRH. Sex, degree of multimorbidity, and pain level ([OR=1.37; p < 0.001] [OR=1.37; p < 0.001] and [OR=1.17; p < 0.001]) were all found to be positively associated with past-year dental visits in the study population., Conclusion: The present study highlights the association between poor SRH, a low level of educational attainment, and less frequent past-year dental visits, as well as the finding that past-year dental visits declined with age in the older adults sampled.

Abstract: The aim of this study was to evaluate the association between sociodemographic factors and noncavitated and cavitated caries lesions in Mexican schoolchildren.This cross-sectional study was conducted in 2020 on 8-to-12-year-old schoolchildren of different socioeconomic status (SES). The caries was evaluated using ICDAS II, SES was evaluated using three categories---a high, middle, or low-income level---of the CONAPO. Multinomial logistic regression analyses were performed in order to ascertain the associations between socioeconomic factors and noncavitated and cavitated caries lesions.The prevalence of noncavitated lesions was 38.0% and cavitated lesions was 43.4% in permanent dentition. In all the samples, 50.6% of schoolchildren had poor oral hygiene. About 52.5% of the mothers and 64.7% of the fathers had less than 9 years of education. Schoolchildren with a low-income level have more cavitated lesions (ICDAS II 4-6) than schoolchildren with high-income level (56.3% vs 15.8%, P = .009). The multinomial logistic regression models showed that mother's level of education <9 years and low-income level were significantly associated with cavitated caries lesions (ICDAS II 4-6), [odds ratio = 1.79 (1.17 - 2.75); P = .007], [OR = 2.21 (1.23 - 3.97); P = .008], respectively. The socioeconomic level was not associated with noncavitated caries lesions (ICDAS II 1-3).An association was found between the presence of cavitated caries lesions and the subject's mother's level of education and a low-income level. Socioeconomic factors were found to be associated with inequalities in caries distribution in the age group studied., (Copyright © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.)
