OBJECTIVE: Identify the variables associated with periodontal status and tooth loss among a sample of adults. MATERIAL AND METHODS: We carried out a cross-sectional study among 161 policemen. Our sample was representative of socioeconomics status and lifestyle among policemen in Campeche, Mexico. All periodontal clinical examinations were assessed using the Florida Probe System using a fixed dental chair and one examiner. The variables we measured included presence of dental plaque, calculus, probing deep, gingival insertion, loss of attachment, gingival retraction, suppuration, and probing blood. We examined six sites surrounding all teeth available in the mouth (maximum 168 sites and excluded third molars). Statistical analyses were performed with STATA 8.2 using a bivariate negative binomial regression model due to over-dispersion in the dependent variable. RESULTS: The mean age was 38.36 +/- 10.99 (range: 20-78). The mean of tooth and sites examined in participants was 24.45 +/- 4.63 and 146.72 +/- 27.80, respectively. The prevalence of tooth loss was 73.3%. 571 teeth were missing and the overall mean of missing teeth was 3.55 +/- 4.63 and within subjects with tooth loss was 4.84 +/- 4.80. The prevalence of functional dentition (21 tooth or more) was 83.8%. To have > 20% gingivitis, > 5% of sites with probing deep > or = 4 mm, > 5% of sites with gingival retraction, > 70% of sites with attachment loss > 2 mm, and each unit of age increase the mean expected of tooth loss by 70.6%, 41.8, 156.4%, 86.9%, and 3.6%, respectively. CONCLUSIONS: Our study findings confirm that lost teeth are common among study participants. Higher prevalence and average of tooth loss was observed among this adult population. Several variables of periodontal status were associated with tooth loss.

OBJECTIVE: To determine the experience, prevalence and severity of dental caries, as well as the Significant Caries Index (SiC) and the treatment needs (TN) in schoolchildren aged six to twelve years. Equally, to estimate the effect of caries in primary dentition on caries in permanent dentition. MATERIAL AND METHODS: A cross-sectional study was realized in 3865 schoolchildren from San Luis Potosí City, Mexico. Subjects were clinically evaluated by three standardized examiners (kappa > 0.85). For detection of caries was employed the WHO's criteria for primary (dmft) and permanent (DMFT) dentitions. In the statistical analyzes non-parametric test and logistic regression were used. RESULTS: Mean of age was 8.69 +/- 1.79 and 51.3% were women. In the primary dentition: dmft index was 1.88 +/- 2.34 and the caries prevalence (dmft >0) of 56.8%. In account to severity 22.0% and 5.6% have dmft >3 and dmft >6, respectively. In children of six years, the caries prevalence was 56.0% and the SiC of 5.45. In the permanent dentition: DMFT index was 1.11 +/- 2.03 and the caries prevalence (DMFT >0) of 36.8%. In account to severity 11.8% and 2.8% have DMFT >3 and DMFT >6, respectively. In children of twelve years, the DMFT index caries 4.14 +/- 4.15 and the SiC of 9.15. The TN index was of 88.5% for primary dentition and 93.6% for the permanent. In logistic regression we observed associated to caries prevalence in permanent dentition; presence of caries in primary dentition (OR = 6.37; p < 0.001), female sex (OR = 1.33; p < 0.001) and higher age (OR = 1.69; p < 0.001). CONCLUSIONS: Caries prevalence to six years old and DMFT index to twelve years old were highest to values established by WHO. Caries severity in the primary dentition was two times than observed in the permanent dentition. High TN in both dentitions was observed. Presence of caries in primary dentition was a strong risk indicator for to present caries in permanent dentition.

OBJECTIVE: To identify the association between tooth brushing frequency and variables of socioeconomic position in Nicaraguan schoolchildren. MATERIAL AND METHODS: A cross sectional study was undertaken in 1353 schoolchildren ages 6 to 12 randomly selected from 25 elementary schools in Leon, Nicaragua. Using a questionnaire addressed to mothers, sociodemographic, socioeconomic and behavioral variables were collected. The dependent variable was tooth brushing frequency, which was dichotomized in 0 "at least one 7 times/week" and 1 "7 or more times/week". A multivariate analysis was carried out with logistic regression in STATA 9. RESULTS: The average age of child participants was 8.99 +/- 2.00 years and 49.7% were women. In the final model, older age (OR = 2.04), female sex (OR = 1.39) and having a mother with positive attitudes toward oral health (OR = 2.5) were positively associated with the tooth brushing frequency (p < 0.05). Larger family size (OR = 0.89) and having low socioeconomic status (1st quartile; OR = 0.54, 2nd quartile; OR = 0.62, 3rd quartile; OR = 0.67) showed a negative relationship with the tooth brushing frequency. To have had at least one preventive dental visit in the previous year was positively associated (p < 0.10) with tooth brushing frequency. CONCLUSION: This study suggested that existence of indicators of socioeconomic inequalities exist even within less developed countries, and thus emphasize the need to target health promotion programs to vulnerable socioeconomic groups.
