Factors associated with lip and oral cavity cancer.

PURPOSE: This study aimed to identify factors associated with the occurrence of primary cancer of the lip and oral cavity regions compared to other types of head and neck cancers according to demographic, socioeconomic data and lifestyle, in Brazil, from 2000 to 2011. METHODS: A study was conducted using Hospital Cancer Records (Instituto Nacional do Câncer), from 2000 to 2011, totaling 23,153 cases. Data were analyzed by binary logistic regression (response category: primary cancers located in the lip and oral cavity; comparison category; other types of primary cancer in the head and neck, which does not affect the lip and oral cavity) at a significance level α = 5%. RESULTS: The study showed factors associated with higher incidence of cancer in the lip and oral cavity: being of advanced age (OR = 1.16), not having a family history of cancer (OR = 2.38), alcohol consumption (OR = 1.17); former tobacco use (OR = 1.51) or current tobacco use (OR = 1.65); having a previous diagnosis of cancer without treatment (OR =1.66). Being female (OR = 0.92), having completed basic (OR = 0.71) and higher (OR = 0.46) education and having previous diagnosis of cancer with treatment (OR = 0.74) constituted factors associated with lower prevalence of cancer of the lip and oral cavity. CONCLUSION: Age, absence of family history of cancer, smoking habits and alcohol consumption, and previous diagnosis of cancer without treatment were associated with a higher incidence of cancer of the lip and oral cavity.

Tooth loss and associated factors in patients with coagulopathies in the State of Paraíba, Brazil.

BACKGROUND: The most common and best known hereditary coagulopathies are hemophilia A and B followed by von Willebrand Disease. OBJECTIVE: This study aimed to estimate the prevalence of tooth loss and investigate its association with demographic and socioeconomic data, as well as to discuss self-reported oral morbidity and use of health services by patients with coagulopathies treated in blood centers in Paraíba, Brazil. METHODS: This was a quantitative cross-sectional epidemiological survey. Data was collected in the period from October 2011 to July 2012 by clinical examination and by assessing interviews using a semi-structured questionnaire. The findings were analyzed by descriptive and inferential statistics with the level of significance (α) being set at 10%. RESULTS: One hundred and six, predominantly male (88.8%), patients with coagulopathies were evaluated. The ages ranged from one to 59 years. Most patients were of mixed race (61.3%), most reported family incomes between R$ 501.00 and R$ 1500.00 (49.1%), and most had not completed elementary school (37.1%). Hemophilia A was found in 76.4% of the cases. The prevalence of dental caries among individuals was 50.0% predominantly in the 13- to 19-year-old age range (66.7%). As regards to tooth loss, teeth were missing in 35.1% of the study participants. CONCLUSION: Tooth loss is high in this population. Males with severe hemophilia A, those who use fluoride and have a good or very good perception about their last dental appointment have a reduced chance of losing their teeth.
