    (Elsevier, 2010-09) Minaya-Sánchez, Mirna; Vallejos-Sánchez, Ana A.; Casanova-Rosado, Alejandro J.; Casanova-Rosado, Juan F.; Medina-Solís, Carlo E.; Maupomé, Gerardo; Márquez-Corona, María de L.; Islas-Granillo, Horacio; Social and Behavioral Sciences, School of Public Health
    Background/purpose To ascertain whether or not clinical attachment loss and tooth loss are present with similar severity and prevalence across the two sides of the mouth in a homogeneous sample of urban male adults. Materials and methods A cross-sectional study was carried out on 161 policemen (a largely homogeneous group in terms of ethnic background, socioeconomic status, sex, occupation, and medical/dental insurance) in Campeche, Mexico. Periodontal examinations were undertaken using the Florida Probe System in a dental chair by one trained and standardized examiner (kappa ≥ 0.60) to determine clinical attachment loss and tooth loss. We examined six sites in all teeth present in the mouth (a maximum of 168 sites, no third molars). Because of correlated data between observations, McNemar (for tooth loss) and Wilcoxon (for attachment loss) signed-rank tests were used to compare right and left sites within the same patient. Results The mean age was 38.4 ± 11.0 years. The mean number of teeth present was 24.4 ± 4.6; the mean number of periodontal sites/person was 146.7 ± 27.8. All P values were ≥ 0.05 (except for attachment loss in the upper first premolars), suggesting that there were no statistically significant differences between the right and left sides for the frequency of presentation of these two conditions. Conclusion Tooth loss and attachment loss measurements largely resemble each other on both sides of the mouth.

    Dental plaque, preventive care, and tooth brushing associated with dental caries in primary teeth in schoolchildren ages 6–9 years of Leon, Nicaragua
    (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.

    (Wolters Kluwer, 2020) Medina-Solis, Carlo E.; Avila-Burgos, Leticia; Borges-Yanez, Socorro A.; Irigoyen-Camacho, Maria E.; Sanchez-Perez, Leonor; Zepeda-Zepeda, Marco A.; Lucas-Rincon, Salvador E.; Medina-Solis, June J.; Marquez-Corona, Maria de L.; Islas-Granillo, Horacio; Casanova-Rosado, Juan F.; Casanova-Rosado, Alejandro J.; Minaya-Sanchez, Mirna; Villalobos-Rodelo, Juan J.; Patino-Marin, Nuria; Mendoza-Rodriguez, Martha; Pontigo-Loyola, America P.; Rosa-Santillana, Ruben de la; Escoffie-Ramierz, Mauricio; Fernandez-Barrera, Miguel A.; Maupome, Gerardo
    To determine the treatment needs and the care index for dental caries in the primary dentition and permanent dentition of schoolchildren and to quantify the cost of care that would represent the treatment of dental caries in Mexico. A secondary analysis of data from the First National Caries Survey was conducted, which was a cross-sectional study conducted in the 32 states of Mexico. Based on dmft (average number of decayed, extracted, and filled teeth in the primary dentition) and DMFT (average number of decayed, extracted, and filled teeth in permanent dentition) information, a treatment needs index (TNI) and a caries care index (CI) were calculated. At age 6, the TNI for the primary dentition ranged from 81.7% to 99.5% and the CI ranged from 0.5% to 17.6%. In the permanent dentition, the TNI ranged from 58.8% to 100%, and the CI ranged from 0.0% to 41.2%. At age 12, the TNI ranged from 55.4% to 93.4%, and the CI ranged from 6.5% to 43.4%. At age 15, the TNI ranged from 50.4% to 98.4%, and the CI ranged from 1.4% to 48.3%. The total cost of treatment at 6 years of age was estimated to range from a purchasing power parity (PPP) of USD $49.1 to 287.7 million in the primary dentition, and from a PPP of USD $3.7 to 24 million in the permanent dentition. For the treatment of the permanent dentition of 12-year-olds, the PPP ranged from USD $13.3 to 85.4 million. The estimated cost of treatment of the permanent dentition of the 15-year-olds ranged from a PPP of USD $10.9 to 70.3 million. The total estimated cost of caries treatment ranged from a PPP of USD $77.1 to 499.6 million, depending on the type of treatment and provider (public or private). High percentages of TNI for dental caries and low CI values were observed. The estimated costs associated with the treatment for caries have an impact because they represent a considerable percentage of the total health expenditure in Mexico.

    Gingival recession and associated factors in a homogeneous Mexican adult male population: A cross-sectional study
    (2012) Minaya-Sánchez, Mirna; Medina-Solís, Carlo-Eduardo; Vallejos-Sánchez, Ana-Alicia; de Lourdes Marquez-Corona, Maria; Pontigo-Loyola, América-Patricia; Islas-Granillo, Horacio; Maupomé, Gerardo
    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.

    Socioeconomic Inequalities and Toothbrushing Frequency among Schoolchildren Aged 6 to 12 Years in a Multi-Site Study of Mexican Cities: A Cross-Sectional Study
    (MDPI, 2022-07-18) Acuña-González, Gladys Remigia; Casanova-Sarmiento, Juan Alejandro; Islas-Granillo, Horacio; Márquez-Rodríguez, Sonia; Benítez-Valladares, David; Mendoza-Rodríguez, Martha; de la Rosa-Santillana, Rubén; de Jesús Navarrete-Hernández, José; Medina-Solís, Carlo Eduardo; Maupomé, Gerardo
    Periodic toothbrushing is the most common, effective, and reliable way to mechanically remove biofilm from oral tissues. The objective of the present study was to determine the association between toothbrushing frequency and socioeconomic position for schoolchildren between 6 and 12 years of age in four cities in Mexico. A cross-sectional study was conducted on 500 Mexican schoolchildren between 6 and 12 years of age from public schools in four Mexican cities. Questionnaires were administered to the parents/guardians of the schoolchildren to obtain the variables included in the study. The dependent variable was toothbrushing frequency, dichotomized as: 0 = less than twice a day and 1 = at least twice a day. The analysis was performed in Stata. The average age of the schoolchildren was 8.9 1.9 years; 50.4% were female. The prevalence of toothbrushing was 52.8% (at least twice a day) (95% CI = 48.4􀀀57.1). In the multivariate model, the variables associated (p < 0.05) with toothbrushing frequency were older age of the schoolchild (OR = 1.14); younger age of the mother (OR = 0.93); being a girl (OR = 1.70); being enrolled in Seguro Popular (OR = 0.69); being in a household that was owned (OR = 2.43); and being a schoolchild who lived in a home that owned a car (OR = 1.31). The prevalence of toothbrushing at least twice a day was just over 50% in these Mexican children. We found demographic and socioeconomic variables to be associated with toothbrushing. Based on socioeconomic variables that were associated with toothbrushing frequency—such as health insurance, home ownership and the household owning a car—the results of the present study confirm the existence of health inequalities in toothbrushing frequency.

    Tooth-Loss Experience and Associated Variables among Adult Mexicans 60 Years and Older
    (2016-06) Islas-Granillo, Horacio; Borges-Yañez, Aida; Medina-Solis, Carlo Eduardo; Lucas-Rincón, Salvador Eduardo; Navarrete-Hernández, José de Jesus; Villalobos-Rodelo, Juan José; Casanova-Rosado, Juan Fernando; Maupome, Gerardo; Department of Cariology, Operative Dentistry and Dental Public Health, IU School of Dentistry
    Objective: This study was conducted to determine the experience of tooth loss, as well as its associated variables, in a sample of adult Mexicans, aged 60 years and older. Materials and Methods: This cross-sectional study was part of a larger project to measure diverse oral health indicators in a convenience sample: it included 139 adult Mexican seniors (69.1% of whom were women), ages 60 years and older, either living in long-term care facilities or living independently and participating in adult day care services. Each participant underwent an oral examination to determine the number of missing teeth. Questionnaires were administered to collect sociodemographic, socioeconomic, and behavioral data. Statistical analyses were performed using nonparametric tests and negative binomial regression. Results: The mean age was 79.06 (±9.78 years). The mean number of missing teeth was 20.02 (±8.61; median, 24); 99.3% of the participants had at least 1 missing tooth, and only 14 had 20 teeth or more. Using a negative binomial regression multivariate model, we found that for each year’s increase in age, the mean number of teeth lost increased by 1% (p<0.05). In individuals who brushed their teeth fewer than two times a day, who had received radiotherapy, or who were currently smokers, the average tooth loss increased 49.2%, 22.6%, and 19.0%, respectively (p<0.01). Conclusion: Tooth-loss experience in these Mexican seniors was very high (20.02±8.61). Older age (within the range of this group of seniors), tooth-brushing patterns, the receipt of radiation therapy, and (current) tobacco use were associated with higher experience of tooth loss.
