Reasons Why Erupted Third Molars Are Extracted in a Public University in Mexico

Purpose: The aim of this study was to determine the reasons for which erupted third molars (3M) are extracted in a sample of Mexican patients. Subjects and methods: A retrospective cross-sectional study was performed on a sample of 83 patients attending exodontia (minor oral surgery) clinics of a public university in Mexico (Autonomous University of Hidalgo State). The outcome variable was the reason for extractions using Kay and Blinkhorn's classification. The independent variables were age, gender, arch and tooth number according to the World Health Organization (WHO). For statistical analysis, we used the Chi-squared test in Stata 9.0. Results: Eighty-three patients underwent 150 3M extractions. Mean age was 38.67 ± 13.96 years, and 71.1% were female. The four reasons for 3M extraction were prosthetic (44.0%), followed by orthodontic (24.7%), dental caries (20.0%) and periodontal disease (11.3%). Differences were observed in the reasons for 3M extractions across age groups (p 0.05), or the WHO tooth number (p > 0.05). Conclusion: Women and patients 18 to 34 years of age had erupted 3M extracted more frequently, primarily for prosthetic reasons. The age profile indicated a trend in demand for services that differ from those of overall tooth extractions, but not for the trend across gender

Frequency of Tooth Brushing and Associated Factors in Mexican Schoolchildren Six to Nine Years of Age

Objective: To determine the prevalence of daily tooth brushing and evaluate some variables associated. Subjects and Methods: A cross-sectional study was carried out in 320 schoolchildren six to nine years old in Campeche, Mexico. Information on sociodemographic and socio-economic variables, oral hygiene practices and attitudes were collected through a questionnaire. The frequency of tooth brushing was categorized as “0” = fewer than seven times/week, “1” = at least once a day. In the analysis, nonparametric tests were used. Results: Mean age was 6.99 ± 1.00 years, 52.5% were boys. The prevalence of daily tooth brushing was 81.6%. In bivariate analysis, the prevalence of tooth brushing was higher (p < 0.05) among the children of mothers with higher schooling (9.80 years vs 8.47 years, p < 0.05), and in younger children (84.6% in 6−7-year olds vs 71.2% in 8−9-year olds, p < 0.05). A slight, non-significant association (p < 0.10) was noted between the current frequency of tooth brushing and an earlier age when the child first started brushing with toothpaste. There were no statistically significant differences (p > 0.05) in the frequency of tooth brushing by gender or by the mother’s attitude toward the oral health of her child. Conclusions: The prevalence of daily tooth brushing was high compared to other studies. Mother’s maximum level of schooling (as an indicator of socio-economic position) was associated with higher frequency of tooth brushing. Maternal characteristics are associated with the oral health behaviour of their children

Diabetes or hypertension as risk indicators for missing teeth experience: An exploratory study in a sample of Mexican adults

Background: To determine an exploratory estimation of the strength of type 2 diabetes mellitus (T2DM) and hypertension diagnoses as risk indicators for missing teeth in a sample of Mexican adults.Materials and Methods: A comparative cross‑sectional study of sixty adult patients in a health center in Mexico included as dependent variable, the number of missing teeth (and having a functional dentition) and as independent variables, diagnoses for diabetes or hypertension, age, sex, maximum level of schooling, and tobacco use. Of the 60 participants, 20 were diagnosed with T2DM, 13 with hypertension, and 27 were  otherwise diagnosed as healthy in their most recent medical checkup. A negative binomial regression (NBR) model was generated. Results: Mean age was 50.7 ± 16.2 and 50.0% were women. Mean number of missing teeth was 4.98 ± 4.17. In the multivariate NBR model, we observed that individuals with T2DM had higher risk of more missing teeth (incidence rate ratios [IRRs] = 3.13; 95% confidence interval [CI] = 2.09–4.69), followed by those with hypertension (IRRs = 2.63; 95% CI = 1.77–3.90). In addition, participants with current tobacco use were significantly more likely to have suffered tooth loss (P &lt; 0.05) than those who were never smokers or former smokers, just like older  participants (P &lt; 0.05). Conclusions: T2DM and hypertension are independently associated with higher experience of missing teeth in an open adult population in Mexico. Future studies with a more sophisticated epidemiological design and encompassing a more detailed landscape of chronic diseases, type and length of use of long‑term medications, and patterns of dental care use are needed to better delineate these associations.Keywords: Adult, hypertension, Mexico, tooth loss, type 2 diabete

As populations age, the prevalence of simultaneous chronic diseases increases, which is known as multimorbidity. Objective: The aim of the present study was to determine the prevalence of multimorbidity and associated factors in a sample of elderly Mexican subjects. Materials and methods: A cross-sectional descriptive study was performed on a convenience sample of 139 subjects aged &ge;60 years. The dependent variable was the multimorbidity diagnosis performed by a physician, which was categorized as 0 for subjects with no chronic disease or only 1&nbsp;disease and 1 for subjects with 2 or more chronic diseases. Questionnaires were used to collect the information on the different variables. A statistical analysis was performed in Stata 11.0. Results: The mean age was 79.06&plusmn;9.78 years, and 69.1% of the subjects were women. A total of 69.1% (95% confidence interval =61.3&ndash;76.8) reported at least 1 morbidity. The mean morbidity by subject was 1.04&plusmn;1.90. Cardiovascular diseases (25.9%), hypertension (20.1%), musculoskeletal disorders (19.4%), and diabetes (13.7%) were the most frequently reported conditions. The prevalence of multimorbidity (2 or more diseases) was 27.3% (95% confidence interval =19.8&ndash;34.8). No significant differences were observed in the independent variables. Conclusion: In conclusion, the prevalence of multimorbidity in this sample of elderly Mexican subjects was relatively low. The distribution across the included variables was not significantly different. Interventions focused on the health care of older adults with multimorbidity should pay special attention to cardiovascular diseases, hypertension, and musculoskeletal disorders.
