Treatment needs for dental caries, restorative care index and index of extractions in adolescents 12 and 15 years old.

OBJECTIVE: To determine the Treatment Needs Index (TNI) for dental caries, the restorative Care Index (CI), and to introduce a Tooth Extractions Index (TEI) to estimate past and current treatment needs among Mexican adolescents. SUBJECTS AND METHODS: A descriptive cross-sectional study was carried out on 1538 adolescents aged 12 and 15 years in the state of Hidalgo, Mexico, to collect decayed, missing, filled teeth (DMFT) data to describe TNI, CI and TEI indices. RESULTS: Higher TNI was identified in younger male teenagers who had always lived in the same community, without dental visits in the last year, and who had poorer socio-economic markers. Higher CI was found in older, female subjects who had moved in their lifetimes to a new community in the area, with dental visits in the last year and who had better socio-economic markers. Higher TEI was found in older, female teenagers who had moved in their lifetimes to a new community in the area, without dental visits in the last year, and who had worse socio-economic markers. CONCLUSIONS: We observed high rates of treatment needs for dental caries and little experience of restorative treatment. While dental extractions due to advanced caries should ideally be zero, relatively few adolescents had this treatment experience. Despite the fact that the overall background of these adolescents is rather homogeneous, it was still possible to find that treatment needs' indices (past and present needs) appeared to be modified by sociodemographic and socio-economic variables.

[Ecologic study in Mexico (2003-2009) on cleft lip and/or palate and associated sociodemographic, socioeconomic and pollution factors]. / Estudio ecológico en México (2003-2009) sobre labio y/o paladar hendido y factores sociodemográficos, socioeconómicos y de contaminación asociados.

OBJECTIVE: To analyze the rates of cleft lip and/or cleft palate (CLP) in Mexico between 2003 and 2009 and assess their association with variables at ecological level, sociodemographic, socioeconomic, and pollution. MATERIAL AND METHODS: An ecological study was conducted with data from the 32 states of Mexico for incidence of CLP, obtained from the Ministry of Health. We included sociodemographic, socioeconomic, and pollution information, obtained from governmental agencies. CLP incidence rates were used as dependent variable; independent variables were socioeconomic, demographic and pollution indicators. Statistical analysis was performed using Spearman correlation and chi(2) tests. RESULTS: During the study period 10573 new cases presented (mean 1510.43 per year). The States with the highest rate (per 1000 births) were: in 2003 the Federal District (Mexico City) (1.76), in 2004 Jalisco (2.62), in 2005 Oaxaca (1.66), in 2006 the State of Mexico (1.29), in 2007, 2008 and 2009 Jalisco (2.17, 2.92, and 1.99). For all the years men were more likely affected than women (P<.05). Variables found positively correlated to LPH rates were total population, solid waste, life expectancy, urban solid waste. The variables negatively correlated were population percentages of high alcohol users, and of alcohol abuse or addiction. CONCLUSIONS: The State of Jalisco was one of the most affected locations over the years. Ecologic positive correlations existed between cleft lip and/or palate and sociodemographic, socioeconomic, and pollution factors. Incidence rate was negatively correlated with alcohol use and abuse. More detailed epidemiological studies are needed to fully characterize risk factors in Mexican populations.

National survey on edentulism and its geographic distribution, among Mexicans 18 years of age and older (with emphasis in WHO age groups).

To determine the prevalence of edentulism in adults aged 18 years and older in Mexico and to describe its distribution in 20 of the 32 States in Mexico, highlighting the experience in the WHO age groups. A secondary analysis of the National Performance Evaluation Survey 2002-2003 (representative at the state level and part of the Word Health Survey) was undertaken. The sample design was probabilistic, stratified and through conglomerates. Data on dental conditions were available only for 20 of the 32 states of Mexico, leading to a total of 24 159 households (N = 54 638 654). The percentage of edentulism was determined as the proportion of subjects that self-reported complete loss of teeth. Data were analyzed using the SVY module for complex surveys in STATA 8.2. The mean age was 41.3 +/- 17.0 years (range 18-99). An estimated 6.3% (N = 3 437 816) of the population > or =18 years was edentulous. Lowest prevalences were observed in the states of Tlaxcala, Puebla and the Estado de Mexico with 3.4%, 3.8% and 4.5%, respectively. Highest prevalences were observed in San Luis Potosí, Colima, and Michoacán with 10.3%, 10.2% and 10.1%, respectively. Following the WHO age groups, the prevalence ranged from 2.4% in the 35-44 group through 25.5% in the 65-74 group. No obvious association between socio-economic and socio-demographic indicators at the state level and prevalence of edentulism was found. The prevalence of complete tooth loss observed in the present study varied greatly across states, although no straightforward association was found with socio-economic and socio-demographic indicators at the state level. This study could serve as a baseline to enable future evaluations of the oral status of Mexican adults and elders, following WHO age groups.
