  ABSTRACT: This study aimed to analyze dental caries patterns among riverine people from Rondônia State, Brazil (Machado and Preto rivers) in 2005 and 2006. A total of 469 subjects were examined, using the World Health Organization form, under natural light, using a wooden tongue depressor and CPI probe in cases of doubts about the presence of dental caries. The results were: 4-5-year age bracket, dmtf = 4.30 and 19.64% caries-free; 6-10 years, DMTF = 1.04, dmtf = 3.52 and 17.05% caries-free; 12 years, DMTF = 2.65 and 30.76% caries-free; 18 years, DMTF = 5.41 and 19.51% caries-free; 35-44 years, DMTF = 17.74 and 2.98% caries-free; 65-74 years, DMTF = 21.56 and 4.34% caries-free. When each component was analyzed separately in the dmtf and DMTF indices, decay was most prevalent in the 0-3, 4-5, 6-10, 12, and 18-year brackets. However, in young and older adults, the most prevalent component was missing teeth. In conclusion, the study population showed a high dental caries index, thus highlighting the need for educational, preventive, and curative measures.

  ABSTRACT: This study was carried out in Monte Negro (state of Rondônia), a village in the Brazilian western Amazon region, where a University of São Paulo Medical School program for medical student training in rural assistance took place. It aimed to determine the prevalence of hepatitis B virus and hepatitis C virus, to investigate risk factors for infection, and to evaluate the State immunization program against hepatitis B virus in the region. The study is a cross-sectional seroprevalence survey, comprising 267 volunteers who answered a comprehensive questionnaire and had blood samples collected, which were analyzed in São Paulo for the presence of antibodies against hepatitis B virus (Hbs Ag, anti-Hbs, and anti-Hbc) and hepatitis C virus using commercial kits. Data were stored in a specific data bank, and the association between seropositivity and potential risk factors was analyzed by means of uni-, bi-, and multi-variate analysis, considering +/- 5%. The seroprevalence of hepatitis B virus was 61.79% and of hepatitis C virus was 0.38%. Statistical analysis on the data bank showed that the prevalence of hepatitis B virus rose significantly with age, especially after adolescence. Infection was higher in those coming from outside the state of Rondônia. Exposure to vaccination against hepatitis B virus was higher in younger individuals and in those who were born in Rondônia. Monte Negro is a highly endemic region for hepatitis B virus but not for hepatitis C virus. Our results also provide indirect evidence indicating a significant improvement in the immunization program in Rondônia in recent years.
