FACTORS ASSOCIATED WITH THE PREVALENCE AND INTENSITY OF DENTAL PAIN IN CHILDREN IN THE MUNICIPALITIES OF THE CAMPINAS REGION, SÃO PAULO.

Objective: The aim of this study was to evaluate the prevalence and intensity of dental pain in children according to size of municipality, associated factors and absenteeism.

A questionnaire was applied to obtain dental pain, demographic, socioeconomic data, and a clinical examination was carried out to evaluate the experience of having a cavity.

[Factors associated with the incidence of dental caries among schoolchildren living in a municipality with low prevalence of dental caries].

The literature has shown that poorer levels of oral health are more frequently related to lower socio-economic status, consequently this cross-sectional and exploratory study conducted in 2003 investigated the association between caries and socio-economic factors, access to care, self-perception and habits among 266 12-year-old schoolchildren living in a community with low prevalence of dental caries. World Health Organization dental caries diagnosis methodology was used, in addition to the application of socio-economic and behavioral questionnaires. To identify the factors associated with dental caries, multivariate logistic regression was used and the dependent variable was synthesized into DMFT=0 and DMFT>0.

[Inequalities in distribution of dental caries in teenagers of Indaiatuba, São Paulo State, 2004].

The objectives of this work was to know the dental caries prevalence and treatment need, besides the distribution of the dental caries in a population of 12 year-old teenagers with high incidence of dental caries. 309 adolescents of public schools of Indaiatuba, São Paulo State, in 2004, were examined. They were selected by process systematic random and the exams followed the World Health Organization criteria.

Dental caries experience in 12-year-old schoolchildren in southeastern Brazil.

The aim of this study was to evaluate the prevalence of caries-free children using DMFT and significant caries (SiC) indexes in different caries prevalence groups in cities of the region of Campinas, São Paulo State, Brazil. The methodology proposed by the World Health Organization (1997) was used for caries diagnosis in 2,378 individuals. According to the DMFT index obtained in each evaluated city, 3 prevalence groups with representative samples were formed, being classified as low, moderate and high.

[Relationship between fluoride levels in the public water supply and dental fluorosis].

Objective: To assess the prevalence of dental fluorosis among schoolchildren subjected to different fluoride concentrations in the public water supply of their cities.

Methods: The sample comprised 386 seven-year-old schoolchildren living in two municipalities in the State of São Paulo that practiced external control over the fluoridation of the water from 1998 to 2002: one with homogenous fluoride concentration and the other with oscillating concentration. Dental fluorosis was determined by dry examination of the upper permanent incisors using Dean's index.

Polarization of dental caries among individuals aged 15 to 18 years.

Objective: To evaluate the role of socioeconomic variables and self-perceived oral health in the polarization of caries among adolescents in Santa Bárbara D'Oeste, Brazil.

Material And Methods: Cross-sectional study. Sampling was randomized and sample size was defined according to WHO criteria.

[Dental caries activity in primary dentition, Indaiatuba, São Paulo, Brazil, 2004].

This study aimed to verify caries activity and analyze caries experience, treatment needs, and enamel defects in 5-year-old preschool children in Indaiatuba, São Paulo State, Brazil. 624 children were selected by systematic random sampling in 2004. WHO criteria were used to measure caries experience and treatment needs.

[Prevalence of enamel defects and the relationship to dental caries in deciduous and permanent dentition in Indaiatuba, São Paulo, Brazil].

The aim of this study was to determine the prevalence of hypoplasia, demarcated opacity and dental fluorosis among schoolchildren with deciduous and permanent dentition. The association between enamel defects and dental caries was also verified. The sample consisted of 624 schoolchildren aged 5 and 309 aged 12.

[Evaluation of simplified DMFT indices in epidemiological surveys of dental caries].

Objective: To analyze whether two simplified indices, "DMF in 6 Teeth"(DMF6T) and "DMF in two quadrants" (DMF2Q), could be indicated for epidemiological surveys of oral health according to dental caries distribution.

Methods: The sample came from epidemiological data in 29 municipalities. A total of 2,378 examinations were done on 12-year-old schoolchildren.

[The current applicability of Viegas simplified indices to dental caries epidemiological surveys].

The aim of this study was to verify whether two simplified Viegas indices, "Method One" and "Method Two", could be recommended for epidemiological surveys. The sample was obtained from secondary data for 29 cities, totaling 2,378 epidemiological tests in 12-year-old schoolchildren. Considering mean DMFT in each city, three prevalence groups were obtained (low, moderate, and high), calculating the estimated value of simplified indices in each group.

Caries experience among schoolchildren in relation to community fluoridation status and town size.

The objective of the present study was to determine the caries experience of schoolchildren aged 7-12 years from the Southeast area of São Paulo State, Brazil, in 1998, according to town size and fluoridation status. Data for this cross-sectional study were based on the data bank from the Epidemiological Survey of São Paulo State provided by the State Health Department. After stratification by fluoridation status and town size, 29 towns were randomly selected to represent the Southeast area of São Paulo State, Brazil, and a total of 13,480 schoolchildren were randomly selected for this study.

[Dental caries in Paulínia, São Paulo State, Brazil, and WHO goals for 2000 and 2010].

An epidemiological survey was conducted in Paulínia, São Paulo State, Brazil, in 2000, aimed at verifying the prevalence of principal oral health problems, using the DMFT index and WHO diagnostic criteria. The sample (1,151) was randomly selected. The dmft was 1.

[Dental caries experience in children at public and private schools from a city with fluoridated water].

The aim of this study was to verify the relationship between type of school as a measure of socioeconomic conditions and caries prevalence among preschoolers and schoolchildren in Rio Claro, São Paulo State, Brazil, a city with fluoridated water supply. The data were secondary, from a sample of 888 children 5 to 12 years old enrolled in private and public schools. Caries was measured by the dmft and DMFT indices as well as the Care index.

[Oral health of schoolchildren residing in areas with or without water fluoridation in Sorocaba, São Paulo State, Brazil].

This study describes dental caries data and fluorosis in seven municipalities in the Sorocaba region, S o Paulo State, Brazil, comparing those with fluoridated as opposed to non-fluoridated water. Criteria were those proposed by the World Health Organization (WHO, 1997), adapted by the School of Public Health, University of S o Paulo. The sample was selected at random, without replacement, and was calculated by age, accepting a design error of 2 and a sampling loss of 20% (n = 96 per age).

[Oral health among preschool children in Brazil, 1999].

Objective: To assess dental decay, gum diseases and fluorosis prevalence and evaluate treatment needs of public preschool children.

Methods: A cross-sectional epidemiological survey on oral health was conducted in 2,805 public preschool children aged 5 and 6 years in Piracicaba, Brazil. Children were examined by a team of ten trained dentists.
