Gingival recession and associated factors in a homogeneous Mexican adult male population : a cross-sectional study
Background: Diverse variables are implicated in the pathogenesis of gingival recession; more detailed knowledge about the relationship between the clinical presentation of gingival recession and assorted risk indicators may lead to improved patient monitoring, early intervention, and subsequent prevention. The objective was to evaluate clinically gingival recession in a homogeneous Mexican adult male population and to determine the strength of association with related factors. Method: A cross-sectional study was carried out in a largely homogeneous group in terms of ethnic background, socioeconomic status, gender, occupation, and medical/dental insurance, in Campeche, Mexico. Periodontal examinations were undertaken to determine diverse clinical dental variables. All periodontal clinical examinations were assessed using the Florida Probe System, a dental chair and one examiner. Questionnaires were used to collect diverse risk indicators. Statistical analyses were undertaken with negative binomial regression models. Results: The mean number of sites with gingival recession per subject was 6.73±5.81; the prevalence was 87.6%. In the negative binomial regression model we observed that for (i) each year of age, and (ii) each percentage unit of increase in sites with plaque, and (iii) with suppuration, mean sites with gingival recession increased 2.9%, 1.0% and 13.0%, respectively. Having a spouse was associated with gingival recession. Conclusions: We observed association between gingival recession, and sociodemographic and clinical parameters. Patients need to be educated about risk indicators for gingival recession as well as the preventive maneuvers that may be implemented to minimize its occurrence. The potential of improved oral self-care to prevent a largely benign condition such as gingival recession is important, given the associated disorders that may ensue root exposure, such as root caries and root hypersensitivity
Out-Of-Pocket Expenditures on Dental Care for Schoolchildren Aged 6 to 12 Years: A Cross-Sectional Estimate in a Less-Developed Country Setting
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 53,578, averaging a PPP of 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
Edentulism and other variables associated with self-reported health status in Mexican adults
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
Influencia de variables predisponentes, facilitadoras y de necesidades sobre la utilización de servicios de salud bucal en adolescentes mexicanos en un medio semirrural
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
Dental plaque, preventive care, and tooth brushing associated with dental caries in primary teeth in schoolchildren ages 6–9 years of Leon, Nicaragua
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

Subgingival Microbiota of Mexicans with Type 2 Diabetes with Different Periodontal and Metabolic Conditions
Background: Type-2-Diabetes (T2D) and Periodontitis are major inflammatory diseases. However, not much is known about the specific subgingival microbiota in Mexicans with diabetes and metabolic dysbiosis. The aim of this study was to describe the subgingival microbiota of Mexicans with T2D and the different periodontal and metabolic conditions, through “Checkerboard” DNA–DNA hybridization. Methods: Subjects were divided into two groups—periodontal-health (PH) (PH_non-T2D; n = 59, PH_T2D; n = 14) and generalized-periodontitis (GP) (GP_non-T2D; n = 67, GP_T2D; n = 38). Obesity (BMI ≥ 30 kg/m2) and serum levels of glycated-hemoglobin (HbA1c), total-lipids, triglycerides, total-cholesterol, high-density-lipids, and low-density-lipids were measured for the T2D individuals. Subgingival microbial identification was processed for 40 species through DNA-probes. Results: Subjects with T2D harbored significantly higher mean total levels (PH: p < 0.001, and GP_NS), a lower proportion of “red” complex (GP: p < 0.01), a higher proportion of “yellow” (GP; p < 0.001), and “orange” (GP; p < 0.01) complex than the non-T2D. GP_T2D individuals exhibited a greater proportion of putative-species—Campylobacter gracilis and S. constellatus (p < 0.001), and Parvimonas micra and Prevotella nigrescens (p < 0.01), than GP_non-T2D. T2D individuals with HbA1c > 8% had presented significantly higher mean pocket-depth and higher levels of G. morbillorum (p < 0.05) and those with obesity or dyslipidemia harbored higher levels, prevalence, or proportion of Streptococcus sp., Actinomyces sp., and Capnocytophaga sp. Conclusions: T2D individuals harbored a particular microbial profile different to non-T2D microbiota. Metabolic control was related to dysbiosis of microbiota—HbA1c>8% related to periodontitis and obesity or dyslipidemia with the predominance of saccharolytic bacteria, irrespective of their periodontal condition
Subgingival Microbiota of Mexicans with Type 2 Diabetes with Different Periodontal and Metabolic Conditions
Caries dental en escolares de 6 a 12 añios de edad en Navolato, Sinaloa, México: experiencia, prevalencia, gravedad y necesidades de tratamiento.
Introducción. La caries dental es una de las enfermedades más prevalentes en los niños. Objetivo. Determinar la experiencia, prevalencia y gravedad de caries en la dentición temporal y permanente; establecer igualmente el índice de caries significativa (SiC, por sus siglas en inglés), en escolares de Navolato, Sinaloa, México, así como sus necesidades de tratamiento. Materiales y métodos. Se realizó un estudio transversal en 3.048 niños de 6 a 12 años de edad. Los sujetos fueron examinados clínicamente por tres examinadores (índice k > 0,85), de acuerdo a los lineamientos establecidos por la Organización Mundial de la Salud (OMS). Para la detección de caries se empleó el criterio de la OMS y la lesión d1 de Pitts. Resultados. La media de edad fue de 8,81±1,79 años y el porcentaje de niñas fue de 52,2%. En la dentición temporal, el ceod (Promedio de dientes cariados, extraídos/perdidos y obturados) fue de 4,68±3,21 y la prevalencia de caries 90,2% (ceod > 3 = 60,8%). El índice significativo de caries fue de 10,52 para los niños de seis años de edad. Las lesiones no cavitadas (d1) representaron 37,1% del componente ""cariados"". En la dentición permanente, el índice CPOD (Promedio de dientes permanentes cariados, perdidos y obturados) fue de 3,24±2,72 y la prevalencia de caries, 82% (CPOD > 3 = 47,8%). El índice de caries significativa fue de 10,87 para los niños de 12 años. Las lesiones no cavitadas representaron 63,4% del componente ""cariados"". Al menos 81,1% de los niños necesitó la restauración de una superficie dental y 89,6%, de dos. Las niñas presentaron más caries que los niños en su dentición permanente. Se observó que conforme aumentó la edad se incrementó la experiencia de caries. Conclusiones. Se observaron altos índices de caries, así como alta prevalencia, gravedad y necesidad de tratamiento. Las lesiones no cavitadas constituyeron el principal porcentaje en la dentición permanente, no así en la dentición temporal
