    (International Scientific Information, 2013) del Socorro Herrera, Miriam; Medina-Solis, Carlo Eduardo; Minaya-Sánchez, Mirna; Pontigo-Loyola, América Patricia; Villalobos-Rodelo, Juan José; Islas-Granillo, Horacio; de la Rosa-Santillana, Rubén; Maupomé, Gerardo
    Background: Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. Material/Methods: A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly selected from 25 schools in the city of León, Nicaragua. Clinical examinations for dental caries (dmft index) were performed by 2 trained and standardized examiners. Socio-demographic, socioeconomic, and behavioral data were self-reported using questionnaires. Multivariate negative binomial regression (NBR) analysis was used. Results: Mean age was 7.49±1.12 years. Boys accounted for 50.1% of the sample. Mean dmft was 3.54±3.13 and caries prevalence (dmft >0) was 77.6%. In the NBR multivariate model (p<0.05), for each year of age, the expected mean dmft decreased by 7.5%. Brushing teeth at least once a day and having received preventive dental care in the last year before data collection were associated with declines in the expected mean dmft by 19.5% and 69.6%, respectively. Presence of dental plaque increased the expected mean dmft by 395.5%. Conclusions: The proportion of students with caries in this sample was high. We found associations between dental caries in the primary dentition and dental plaque, brushing teeth at least once a day, and having received preventive dental care. To improve oral health, school programs and/or age-appropriate interventions need to be developed based on the specific profile of caries experience and the associated risk indicators.

    (Universidad Autónoma de Campeche, 2023) Jiménez-Gayosso, Sandra Isabel; Morales-Luckie, Raúl Alberto; Robles-Bermeo, Norma Leticia; Hernández-Martínez, César Tadeo; Ramírez-Cardona, Marius; Pontigo-Loyola, América Patricia; Sosa-Velasco, Taurino Amílcar; García-Hernández, Verónica; Medina-Solís, Carlo Eduardo; Maupomé, Gerardo
    Objetivo: Detectar la presencia y concentración de hierro (Fe), cromo (Cr) y níquel (Ni) en saliva de pacientes que requieren rehabilitación con coronas metálicas prefabricadas (CMP), antes y después de su colocación. Material y Métodos: Se realizó un estudio cuasi-experimental (antes-después) en 32 pacientes que asistieron a atención odontológica en una clínica de odontopediatría de una universidad pública y que requirieron rehabilitación con CMP. Se tomaron muestras de 5 ml de saliva no estimulada por paciente de acuerdo con las pautas estandarizadas. La primera muestra se tomó antes de la rehabilitación de los CMP, y las otras dos se tomaron 1 semana y 1 mes después de la colocación de los PMC. Los niveles de metal se midieron mediante espectrometría de emisión óptica de plasma acoplado inductivamente (ICP-OES). Se realizaron pruebas paramétricas (ANOVA y correlación de Pearson), y se consideró estadísticamente significativa una p<0,05. Resultados: La edad media fue de 5.71±1.72 años y el 53.1% eran mujeres. Se encontraron diferencias estadísticamente significativas al comparar la liberación de Ni antes, 1 semana y 1 mes después de colocar las coronas. De manera similar, observamos una correlación positiva entre el número de coronas y la liberación de Ni. Las cantidades de Fe y Cr fueron inferiores a 0,1 ppb, lo que no fue detectable por ICP-OES. Hubo una ligera correlación negativa entre el número de coronas y los valores basales de Ni (r = −0.342, p = 0.056). Conclusión: Se observaron cambios, antes y después de colocar las PMC, en los niveles de Ni. Los niveles de Fe y Cr fueron inferiores a 0,1 ppb, por lo que no fueron evaluables. Los niveles de Fe, Cr y Ni liberados estaban por debajo de los niveles tóxicos para la salud.

    Edentulism and other variables associated with self-reported health status in Mexican adults
    (International Scientific Information, Inc., 2014) Medina-Solís, Carlo Eduardo; Pontigo-Loyola, América Patricia; Pérez-Campos, Eduardo; Hernández-Cruz, Pedro; Avila-Burgos, Leticia; Mendoza-Rodríguez, Martha; Maupomé, Gerardo
    Background: To determine if edentulism, controlling for other known factors, is associated with subjective self-report health status (SRH) in Mexican adults. Material and methods: We examined the SRH of 13 966 individuals 35 years and older, using data from the National Survey of Performance Assessment, a cross-sectional study that is part of the technical collaboration between the Ministry of Health of Mexico and the World Health Organization, which used the survey instrument and sampling strategies developed by WHO for the World Health Survey. Sociodemographic, socioeconomic, medical, and behavioral variables were collected using questionnaires. Self-reported health was our dependent variable. Data on edentulism were available from 20 of the 32 Mexican states. A polynomial logistic regression model adjusted for complex sampling was generated. Results: In the SRH, 58.2% reported their health status as very good/good, 33.8% said they had a moderate health status, and 8.0% reported that their health was bad/very bad. The association between edentulism and SRH was modified by age and was significant only for bad/very bad SRH. Higher odds of reporting moderate health or poor/very poor health were found in women, people with lower socio-economic status and with physical disabilities, those who were not physically active, or those who were underweight or obese, those who had any chronic disease, and those who used alcohol. Conclusions: The association of edentulism with a self-report of a poor health status (poor/very poor) was higher in young people than in adults. The results suggest socioeconomic inequalities in SRH. Inequality was further confirmed among people who had a general health condition or a disability. Dentists and health care professionals need to recognize the effect of edentulism on quality of life among elders people.

    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, Gerardo
    The 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.

    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, Gerardo
    Objetivo: 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.

    National Survey of Oral/Dental Conditions Related to Tobacco and Alcohol Use in Mexican Adults
    (MDPI, 2014-03) Medina-Solís, Carlo Eduardo; Pontigo-Loyola, América Patricia; Pérez-Campos, Eduardo; Hernández-Cruz, Pedro; Ávila-Burgos, Leticia; Mendoza-Rodríguez, Martha; Maupomé, Gerardo; Periodontics and Allied Dental Programs, School of Dentistry
    Oral diseases are a major burden on individuals and health systems. The aim of this study was to determine whether consumption of tobacco and alcohol were associated with the prevalence of oral/dental problems in Mexican adults. Using data from the National Performance Evaluation Survey 2003, a cross-sectional study part of the World Health Survey, dental information from a representative sample of Mexico (n = 22,229, N = 51,155,740) was used to document self-reported oral/dental problems in the 12 months prior to the survey. Questionnaires were used to collect information related to sociodemographic, socioeconomic, and other risk factors. Three models were generated for each age group (18–30, 31–45 and 46–98 years). The prevalence of oral/dental conditions was 25.7%. Adjusting for sex, schooling, socioeconomic position, diabetes, and self-reported health, those who used tobacco (sometimes or daily) (OR = 1.15, p = 0.070; OR = 1.24, p < 0.01; and OR = 1.16, p < 0.05, for each age group respectively) or alcohol (moderate or high) (OR = 1.26, p < 0.001; OR = 1.18, p < 0.01 and OR = 1.30, p < 0.001, for each age group respectively) had a higher risk of reporting oral/dental problems. Because tobacco and alcohol use were associated with self-reported oral/dental problems in one out of four adults, it appears advisable to ascertain how direct is such link; more direct effects would lend greater weight to adopting measures to reduce consumption of tobacco and alcohol for the specific purpose of improving oral health.

    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 Dentistry
    Aim: 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.

    Principales razones de extracción de dientes permanentes en una muestra de adultos mexicanos
    (2013) Medina-Solís, Carlo Eduardo; Pontigo-Loyola, América Patricia; Pérez-Campos, Eduardo; Hernández-Cruz, Pedro; De la Rosa-Santillana, Rubén; de Jesús Navarete-Hernández, José; Maupomé, Gerardo
    Background. Tooth extractions are one of the most common procedures in oral surgery. The objective of this study was to identify the reasons for tooth extraction in adult patients seeking care at teaching dental clinics. Material and methods. A cross-sectional study was carried out in 331 subjects between 18 and 85 (45.37± 13.85) years of age seeking dental care in dental clinics of the Universidad Autónoma del Estado de Hidalgo, from January 2009 to December, 2009. Data pertaining to age, sex, tooth number and the reason for extraction according to Kay & Blinkhorn were analyzed with non-parametric tests. Results. 779 extractions were undertaken. The main reason for extraction was dental caries (43.1%), periodontal disease (PD) (27.9%), and prosthetic reasons (21.5%). There was no significant difference across sex for reasons of extraction (p › 0.05). Significant differences (p ‹ 0.001) were found for age (extraction due to periodontal disease increased with age); in patients attending in a single visit vs. patients attending a series of dental appointments (caries reasons were more common in patients having a single appointment vs. PD in those attending a series of appointments); for type of teeth (upper, posterior, and molars were extracted primarily because of caries, while lower, anterior and incisors were more often extracted because of PD). Conclusions. Dental caries was the most common reason for tooth extraction, followed by periodontal disease. Differences in the reasons for extraction were observed across patient characteristics and type of tooth.
