    OBJECTIVE:To examine the relationship between the presence of enamel defects, dental caries in primary teeth, and exposure to various fluoride technologies and the presence of dental caries in permanent teeth in children with mixed dentition. MATERIALS AND METHODS:A cross-sectional study was conducted in 713 children aged 6-9 years old in 4 elementary schools in Campeche, Mexico through the use of a questionnaire for the mothers and an oral examination in the children. The dependent variable was the prevalence of caries in permanent dentition. RESULTS:The mean number of decay, missing or filling teeth in primary dentition (dmft) and in permanent dentition (DMFT) was 2.48 (2.82) (deft > 0 = 58.9%) and 0.40 (0.98) (DMFT > 0 = 18.2%), respectively. The significant caries index (SiC), which is calculated in deciduous dentition, was 5.85 for 6 year-olds. Multivariate logistic regression adjusted for variables related to fluoride exposure revealed that older age (OR = 2.99), a deft of > 0 (OR = 5.46), and lower maternal educational level (OR = 1.57) were significantly associated with a higher number of dental caries in permanent teeth. An interaction between sex and enamel defects was also found. CONCLUSIONS:The number of dental caries in both primary and permanent dentitions was relatively smaller than that found in prior studies performed in Mexican populations. The results confirm that the presence of caries in primary dentition is strongly associated with caries in permanent dentition. No significant relationship was found between fluoride exposure and dental caries in permanent dentition.

    (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.

    Prevalence of Functional Dentition in a Group of Mexican Adult Males

    Objective: 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.

    Prevalencia de fluorosis dental en ocho cohortes de mexicanos nacidos durante la instauración del Programa Nacional de Fluoruración de la Sal Doméstica
    (2013) Casanova-Rosado, Alejandro José; Medina-Solís, Carlo Eduardo; Casanova-Rosado, Juan Fernando; Vallejos-Sánchez, Ana Alicia; de la Rosa-Santillana, Rubén; Mendoza-Rodríguez, Martha; Villalobos-Rodelo, Juan José; Maupomé, Gerardo
    Objective: to determine the effect of birth cohort on dental fluorosis in Mexican schoolchildren during the implementation of the national program to fluoridate domestic salt. Material and methods: in a cross-sectional study we examined 1,644 schoolchildren 6-13 years old born between 1985-1992 in Campeche, México; a community where there is negligible naturally available fluoride in water supplies. Dental fluorosis was assessed with the Dean’s index in the permanent dentition. Questionnaires were used to identify diverse socio-demographic and socio-economic variables. In the statistical analysis logistic regression was used. results: the prevalence of fluorosis was 15.5%. In the multivariate model, we observed fluorosis was associated with larger family sizes (OR: 0.91; 95% CI: 0.84-0.99) and female sex (OR: 0.74; 95% CI: 0.57-0.98). Furthermore, using the cohort of 1985 as a comparison group, no significant dental fluorosis differences were found with those born between 1986-1987; in contrast, in the cohorts born between 1989-1992 the risk of dental fluorosis increased by almost four times (p < 0.05). conclusion: the prevalence of fluorosis was low compared to other studies in Mexico. In this community with negligible fluoride in water supplies the likelihood of dental fluorosis increased as the windows of susceptibility in birth cohorts were closer to the chronologic beginning of the national domestic salt fluoridation program in 1991. This trend was more apparent after 1991.

    Tooth brushing frequency in Mexican schoolchildren and associated sociodemographic, socioeconomic, and dental variables
    (International Scientific Information, Inc., 2014) Casanova-Rosado, Alejandro José; Medina-Solís, Carlo Eduardo; Casanova-Rosado, Juan Fernando; Vallejos-Sánchez, Ana Alicia; Minaya-Sánchez, Mirna; Mendoza-Rodríguez, Martha; Márquez-Rodríguez, Sonia; Maupomé, Gerardo
    Background: Tooth brushing (with fluoridated toothpaste) is the most cost-effective intervention in dentistry and it is widely recommended to preserve good oral health. We aimed to determine the frequency of tooth brushing and the variables associated with this practice in schoolchildren living in southeast Mexico. Material and methods: A cross-sectional study was carried out in 1644 schoolchildren, 6 to 13 years old. Questionnaires with socio-demographic, socioeconomic, and dental variables were administered to mothers/guardians of children. The dependent variable was the frequency of tooth brushing, which was categorized as 0 = tooth brushing less than once a day and 1 = tooth brushing at least once a day. A logistic regression model was used to evaluate the final results. Results: Mean age was 9.06±2.02 years and 49.1% were girls. The prevalence of tooth brushing at least once a day was 49.8%. In the multivariate model, characteristics related to tooth brushing frequency (p<0.05) were: older age (OR=1.11), being female (OR=1.64), having a larger family (OR=0.87), having had a visit to a dentist during the year preceding the study (OR=1.37), and having had fluoride applications by a professional (OR=1.39). Conclusions: The results suggested that different variables (demographic, socioeconomic and dental) are associated with the frequency of tooth brushing. Family size (proxy variable for socioeconomic status) may indicate certain oral health inequalities in this population.
