Item Comparative Analysis of Edentulism in a Sample of Mexican Adults with and without Type 2 Diabetes(MDPI, 2022) Islas-Zarazúa, Rosalina; Mora-Acosta, Mariana; Navarrete-Hernández, José de Jesús; Reynoso-Vázquez, Josefina; Villalobos-Rodelo, Juan José; Rojas-Ortega, Laura; Sosa-Velazco, Taurino Amilcar; Márquez-Corona, María de Lourdes; Medina-Solís, Carlo Eduardo; Maupomé, GerardoThe objective of the present study was to compare the prevalence of edentulism in Mexican adults with and without a diagnosis of type 2 diabetes mellitus (T2DM) when they are seeking dental care. A cross-sectional study was conducted on 1921 medical records of Mexican adults 40 years of age and older who sought dental care at clinics of a public university in Mexico. The dependent variable was edentulism, clinically determined through an oral examination. The main independent variable was the self-report of previous T2DM diagnosis made by a physician. Sociodemographic, socioeconomic and behavioral covariates were included in a multivariate binary logistic regression model. Overall edentulism prevalence was 8.4% (95% CI = 7.1–9.6). The prevalence of T2DM was 14.3% (n = 274). The prevalence of edentulism among individuals with T2DM was 13.1%, but only 7.6% among individuals without T2DM. In the multivariate binary logistic regression model, a previous T2DM diagnosis increased the probability of being edentulous 1.61 times (95% CI = 1.03–2.50). For each year a person’s age increased, the likelihood of being edentulous increased by 12% (95% CI = 10–14%). In summary, a higher prevalence of edentulism was present in Mexican adults with T2DM and in those of older age. This information may be used by dental care providers and health policymakers to improve approaches to preventive care, as well as to characterize and anticipate care needs more accurately for the adult and older adult populations.Item Factors Associated with Self-Report of Type 2 Diabetes Mellitus in Adults Seeking Dental Care in a Developing Country(Wiley, 2023) López-Gómez, Sandra Aremy; González-López, Blanca Silvia; Scougall-Vilchis, Rogelio José; Márquez-Corona, María de Lourdes; Minaya-Sánchez, Mirna; Navarrete-Hernández, José de Jesús; de la Rosa-Santillana, Rubén; Acuña-González, Gladys Remigia; Pontigo-Loyola, América Patricia; Villalobos-Rodelo, Juan José; Medina-Solís, Carlo Eduardo; Maupomé, GerardoThe aims of the present study were to identify the prevalence and risk indicators of type 2 diabetes mellitus (T2DM) in urban-based Mexican adults seeking care in a university-based triage/intake dental clinic, and to develop a predictive model. A cross-sectional study was conducted on 3354 medical/dental records of adults who sought care at the triage/intake dental clinics of a public university. The dependent variable was self-report of a previous diagnosis of T2DM made by a physician. Several socio-demographic and socioeconomic covariates were included, as well as others related to oral and general health. A multivariate binary logistic regression model was generated. We subsequently calculated well-known statistical measures employed to evaluate discrimination (classification) using an (adjusted) multivariate logistic regression model (goodness-of-fit test). The average age of patients was 42.5 ± 16.1 years old and the majority were female (64.1%). The prevalence of T2DM was 10.7% (95%CI = 9.7–11.8). In the final multivariate model, the variables associated (p < 0.05) with the presence of T2DM were older age (40 to 59 years old, OR = 2.00; 60 to 95 years old, OR = 2.78), having any type of health insurance (OR = 2.33), having high blood pressure (OR = 1.70), being obese (OR = 1.41), and having a functional dentition (OR = 0.68). Although the global fit of the model and the calibration tests were adequate, the sensitivity (0.0%) and positive predictive (0.0%) values were not. The specificity (100%) and negative predictive (89.3%) values, as well as the correctly classified (89.3%) value, were adequate. The area under the ROC curve, close to 0.70, was modest. In conclusion, a prevalence of T2DM of 10.7% in this sample of Mexican adults seeking dental care was similar to national figures. Clinical (blood pressure, BMI and functional dentition), demographic (age), and socioeconomic (health insurance) variables were found to be associated with T2DM. The dental setting could be appropriate for implementing preventive actions focused on identifying and helping to reduce the burden of T2DM in the population.Item Influencia de variables predisponentes, facilitadoras y de necesidades sobre la utilización de servicios de salud bucal en adolescentes mexicanos en un medio semirrural(2012) Pontigo-Loyola, América Patricia; Medina-Solís, Carlo Eduardo; Márquez-Corona, María de Lourdes; Vallejos-Sánchez, Ana Alicia; Minaya-Sánchez, Mirna; Escoffié-Ramírez, Mauricio; Maupomé, GerardoObjetivo: El propósito de este estudio fue identificar las variables predisponentes, facilitadoras y de necesidades de salud que influyen sobre las visitas al dentista que realizan adolescentes mexicanos. Material y Métodos: Se trata de un estudio de diseño transversal analítico en el que se incluyeron 1,538 adolescentes mexicanos de 12 y 15 años de edad. La variable dependiente fue la utilización de servicios de salud bucal (USSB) en el año previo al estudio. Los datos fueron recogidos a través de un cuestionario e incluyeron variables sociodemográficas, socioeconómicas y conductuales. El estudio también incluyó un examen clínico bucal. El análisis incluyó estadística no paramétrica y se generó un modelo de regresión logística. Resultados: De los 1538 adolescentes, 688 tenían 12 años de edad y 850 15 años. Las niñas representaron 49.9%. La prevalencia de USSB fue 15%. En el modelo final se asociaron a la USSB (p<0.05) haber cambiado de residencia donde se nació (RM=1.24), comprar agua purificada para consumo en lugar de usar agua intra-domiciliaria (RM=1.52), mejor escolaridad de la madre (RM=1.39) y del padre (RM=1.87), así como el número de dientes sanos (RM=0.96) y tener al menos un diente con caries (RM=1.10). Conclusiones: El porcentaje de sujetos con USSB en el último año fue bajo comparado con otros estudios. Nuestra cuantificación de las variables indicadoras muestran que algunas se encuentran asociadas a la USSB (predominantemente las de posición socioeconómica), lo que indica la existencia de desigualdades en salud bucal y la necesidad de establecer estrategias para reducir las brechas observadas.Item Out-Of-Pocket Expenditures on Dental Care for Schoolchildren Aged 6 to 12 Years: A Cross-Sectional Estimate in a Less-Developed Country Setting(MDPI, 2019-06-05) Medina-Solís, Carlo Eduardo; Ávila-Burgos, Leticia; Márquez-Corona, María de Lourdes; Medina-Solís, June Janette; Lucas-Rincón, Salvador Eduardo; Borges-Yañez, Socorro Aida; Fernández-Barrera, Miguel Ángel; Pontigo-Loyola, América Patricia; Maupomé, Gerardo; Periodontics, IU School of DentistryAim: The objective of this study was to estimate the Out-Of-Pocket Expenditures (OOPEs) incurred by households on dental care, as well as to analyze the sociodemographic, economic, and oral health factors associated with such expenditures. Method: A cross-sectional study was conducted among 763 schoolchildren in Mexico. A questionnaire was distributed to parents to determine the variables related to OOPEs on dental care. The amounts were updated in 2017 in Mexican pesos and later converted to 2017 international dollars (purchasing power parities-PPP US $). Multivariate models were created: a linear regression model (which modeled the amount of OOPEs), and a logistic regression model (which modeled the likelihood of incurring OOPEs). Results: The OOPEs on dental care for the 763 schoolchildren were PPP US $53,578, averaging a PPP of US $70.2 ± 123.7 per child. Disbursements for treatment were the principal item within the OOPEs. The factors associated with OOPEs were the child's age, number of dental visits, previous dental pain, main reason for dental visit, educational level of mother, type of health insurance, household car ownership, and socioeconomic position. Conclusions: The average cost of dental care was PPP US $70.2 ± 123.7. Our study shows that households with higher school-aged children exhibiting the highest report of dental morbidity-as well as those without insurance-face the highest OOPEs. An array of variables were associated with higher expenditures. In general, higher-income households spent more on dental care. However, the present study did not estimate unmet needs across the socioeconomic gradient, and thus, future research is needed to fully ascertain disease burden.Item Prevalence of Functional Dentition in a Group of Mexican Adult Males(University of Puerto Rico Medical Sciences Campus, 2017-09) Minaya-Sánchez, Mirna; Medina-Solís, Carlo Eduardo; Casanova-Rosado, Juan Fernando; Vallejos-Sánchez, Ana Alicia; Casanova-Rosado, Alejandro José; Márquez-Corona, María de Lourdes; Mendoza-Rodríguez, Martha; Maupomé, Gerardo; Cariology, Operative Dentistry and Dental Public Health, School of DentistryObjective: To determine the prevalence of functional dentition and associated periodontal variables in a sample of Mexican adult males. Methods: A cross-sectional study of 161 policemen in Campeche, Mexico, was carried out. A clinical examination using an electronic probe was used to collect variables (dental plaque, periodontal pockets, gingival recession, suppuration, and bleeding on probing) on 6 periodontal sites (a maximum of 168 sites, excluding third molars). Sociodemographic, socioeconomic, and behavioral variables were collected through a self-administered survey. Functional dentition was defined as having 21 or more natural teeth. Data were analyzed with STATA 11.0, using logistic regression models. Results: Mean age was 38.3 (±10.9) years. The prevalence of having a functional dentition was 83.8% in the sample. The odds of having a functional dentition declined with age (odds ratio [OR] = 0.93), having diabetes (OR = 0.27) and with having a high percentage of sites with plaque (OR = 0.77), with bleeding on probing (OR = 0.97), and with gingival recession (OR = 0.82). Conclusion: While a large proportion of subjects had a functional dentition in this community-dwelling sample of adult Mexican males, the likelihood of their having a functional dentition decreased with age, with their having been diagnosed with diabetes, and with assorted negative indicators of periodontal/gingival status.
