[Prevalence of dental caries and treatment needs in 6 to 12 year-old schoolchildren at public schools]. / Prevalência de cárie e necessidades de tratamento em escolares de 6 a 12 anos da rede pública de ensino.

OBJECTIVE: To assess dental caries prevalence and treatment needs of schoolchildren in the State of Goiás, Brazil. METHODS: The study population consisted of 6-12-yr-old schoolchildren (n=1,419), male and female, attending 25 public schools located in the urban area of 9 provincial cities in the State of Goiás. RESULTS: Percentage of caries-free schoolchildren was very low at all ages (4.4% at age 12). Mean DMF-T ranged from 0.41 at age 6 to 5.19 at age 12. Mean dmf-t in this age group ranged from 4.93 to 0.29. Treatment needs were higher than the proportion of treated teeth in both deciduous and permanent dentition. CONCLUSION: The high prevalence of dental caries found in schoolchildren in the provincial cities of Goiás suggests the need for oral health education and preventive programs targeted at the underlying causes of the disease on a population level.

[The prevalence of dental caries and necessary treatment in six to twelve year old schoolchildren in Goiânia, GO, Brazil, 1994]. / Prevalência de cárie e necessidades de tratamento em escolares de seis a doze anos de idade, Goiânia, GO, Brasil, 1994.

OBJECTIVE: The prevalence of dental caries and needs of treatment among schoolchildren in Goiânia-GO, middle-west of Brazil was assessed. METHODOLOGY: The study population consisted of 6-12-yr-old schoolchildren (n = 1,400) attending public schools located in the urban area of the city, where the water-supply had been fluoridated for 9 years. RESULTS: Mean dmf-t and DMF-T for the total sample were 2.19 and 2.86, respectively, showing a reduction of 57.1% in the DMF-T as compared to the regional data from the national survey carried out in 1986. At age 12 DMF-T was 4.59, which is above the acceptable level according to the FDI/WHO goal for the year 2000. Percentage of caries-free schoolchildren was very low at all ages (11% of the total sample). The most significant need was for restorative treatment in the treatment deciduous dentition at all ages and in the permanent dentition from age 9. CONCLUSION: It was concluded that the prevalence of dental caries among schoolchildren in Goiânia-GO is high, comparable to the situation in most Latin American countries and poor regions of developed countries. The results indicate the need for oral health education and preventive programs targeted at the underlying causes of the disease, in the population.

Post-mortem diagnosis of chronic Chagas's disease comparative evaluation of three serological tests on pericardial fluid.

In an attempt to improve the post-mortem diagnosis of Chagas's disease the authors performed haemagglutination tests (HAT), fluorescent Trypanosoma cruzi antibody tests (FAT), and complement fixation tests (CFT) on the pericardial fluid obtained at autopsy of 50 individuals with Chagas's heart disease, and 93 patients in whom this disease was not thought to be present. The results demonstrate that all three tests are efficient for the post-mortem diagnosis of Chagas's disease but suggest that their combined use would detect more cases than would one isolated reaction only.
