The characteristics of the temporomandibular joint (TMJ) are essential in orthodontic and prosthetic treatments. Previous studies have suggested an association between articular eminence inclinations (AEI) and occlusal plane characteristics using radiographs, but no bilateral analysis has been conducted using cone beam computed tomography (CBCT). Objective: This study aimed to investigate the specific characteristics of the occlusal plane inclinations associated with unilateral and bilateral AEI using CBCT. Methods: We conducted a cross-sectional study to evaluate 200 temporomandibular joints (TMJs) from 100 records obtained at the orthodontic department. We evaluated the association between the AEI, and occlusal plane characteristics like the cant of the occlusal angle, occlusal plane angles, inclination of the upper incisor to the Frankfort plane and palatal plane using both bivariate and multivariate analyses both unilaterally and bilaterally. Results: Our findings suggested statistically significant associations (p < 0.050) between AEI (bilateral) and occlusal inclination parameters, including the cant of the occlusal plane (Coef. −0.38; 95%CI −0.70:−0.06; p = 0.017), occlusal plane angle (Coef. −0.39; 95%CI −0.740:−0.05; p = 0.024), and position of the upper incisor relative to the palatal plane (Coef. −0.34; 95%CI −0.63:−0.06; p = 0.016). Conclusion: This study suggests an association between dental inclinations and AEI, which reflects the anatomical characteristics of TMJ and its related dental structures. [ABSTRACT FROM AUTHOR]

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]

Objective: To assess vaccination coverage in children under seven years of age., Materials and Methods: Study based on the Halfway National Health and Nutrition Survey (Ensanut MC 2016)., Results: Full vaccination coverage in children <1 year was 51.7%, (range: 67.6% [pentavalent (PV)] to 93.9% [BCG]), in those aged 12-23 months was 53.9% (range: 68.5% [MMR] to 98.3% [BCG]) and in those 24-35 months was 63.2% (range: 85.3% [pneumococcal]) to 98.6% [BCG]). In children aged six years, the coverage of 1 MMR dose was 97.8% and 50.7% for two doses. Only 2.2% of six year olds were not vaccinated. Variables associated with incomplete schedule were age of 2-5 months, mother being under 20 years of age or maternal language indigenous., Conclusions: The vaccination program needs to improve recruitment of newborns and their follow-up until they complete their immunization schedule, taking advantage of the local contacts with health services to vaccinate them., Competing Interests: Declaration of conflict of interests. The authors declare that they have no conflict of interests.

Objective: To estimate the prevalence of acute diarrheal diseases (ADD) during the two weeks previous to the interview among children <5 years of age and to describe alarm signs and feeding practices of parents and caregivers (PCG) during children's ADD., Materials and Methods: Analysis of data from the National Health and Nutrition Surveys 2012 and 2006 and the National Health Survey 2000., Results: ADD prevalence decreased significantly from 2006 (13.1%) to 2012 (11.0%), particularly in the lower socioeconomic status. "Frequent bowel movements" were the main warning sign identified by PCG (66.0%) in contrast to "crying without tears" (4.3%) and "blood in faeces" (0.5%); only 42% PCG reported administering oral rehydration therapy. Factors associated with ADD were child's age <1 year and mother's age <20 years., Conclusions: It is necessary to reinforce appropriate ADD preventive and treatment practices among PCG of children <5 years of age.

Objective: To estimate vaccination coverage in adults 20 years of age and older., Materials and Methods: Analysis of data obtained from the National Health and Nutrition Survey 2012., Results: Among adults 20-59 years old coverage with complete scheme, measles and rubella (MR) and tetanus toxoid and diphtheria toxoid (Td) was 44.7,49. and 67.3%, respectively. Coverage and percentage of vaccination were significantly higher among women than men. Among women 20-49 years coverages with complete scheme, MR and Td were 48.3, 53.2 and 69.8%, respectively. Among adults 60-64 years old, coverage with complete scheme, Td and influenza vaccine were 46.5, 66.2 and 56.0%, respectively. Among adults >65 years coverages for complete scheme, Td, influenza vaccine and pneumococcal vaccine were 44.0, 69.0, 63.3 and 62.0%, respectively., Conclusion: Vaccination coverage among adult population as obtained from vaccination card or self-report is below optimal values although data may be underestimated. Recommendations for improvements are proposed.

Background: Indoor air pollution produced by biomass cooking fuels in developing countries has been associated with acute and chronic lower respiratory diseases, but has not been identified as an occupational exposure among women., Objective: To examine the relationship between the use of biomass cooking fuels (mainly wood) and tuberculosis (TB) among women living in rural areas in Southern Mexico., Methods: We conducted a population based case-control study in the health jurisdiction of Orizaba, Mexico. Cases were all incident female pulmonary TB patients, with Mycobacterium tuberculosis in sputum, living in communities with fewer than 15,000 inhabitants, diagnosed between March 1995 and April 2003. Woodsmoke exposure was assessed by applying a standardized questionnaire (ATS-DLD-78 questionnaire). Controls were randomly selected from sex-matched neighbors. Appropriate IRB approval was obtained., Results: 42 TB cases and 84 community controls were recruited. Multivariate assessment showed that more than 20 years of exposure to smoke from biomass fuels was three times more frequent among cases than among controls [Odds ratio (OR): 3.3, 95% confidence interval (CI):1.06-10.30, p = 0.03], after controlling for age, body mass, household crowding, years of formal education and tobacco use., Conclusions: We found a strong association between the use of biomass cooking fuels and tuberculosis among women in a community-based, case-control study. Results of this study are intended to provide evidence to policy makers, community leaders and the general public on the importance of implementing gender oriented interventions that decrease the use of biomass fuels in poor communities in developing countries.
