The purpose of this study was to evaluate the efficacy of non-invasive methods of treatment for active incipent occlusal caries. Anamnesis, professional prophylaxis, and visual inspection were used to classify 250 Brazilian pre-school-children. First permanent decayed molars (n=98) from thirty-one subjects (6 years+ 6 months) were selected and divided into(More)
OBJECTIVES To determine the influence of diagnostic adjuncts (dental brushing and drying) in dental caries diagnosis. To analyse the underestimation levels in epidemiological examinations when compared to traditional dental setting examinations. To evaluate the influence of including noncavitated (NC) carious lesions in the estimation of the disease. (More)
OBJECTIVE To investigate the influence of different settings, epidemiological and clinical, and different diagnostic thresholds on caries detection in a group of 7-10-year-old children in Brazil. MATERIALS AND METHODS In total, 983 children aged 7-10 years old and enrolled in four public schools were randomly selected. Three examiners performed(More)
The aim of this study was to evaluate retention and efficacy of polyacid-modified composite resin used as fissure sealant (Variglass V.L.C.) after six years. Three-hundred and seventy permanent first molars were sealed. After six years, 42.0% of the original group was re-examined and the sealant was found to be totally present in 3.4%, partially present in(More)
The aim of this study was to evaluate in vitro the marginal microleakage of different materials used as pit-and-fissure sealants (Delton, Filtek Flow, Dyract Flow and Vitremer). Fifty-six extracted sound human third molars were randomly assigned to 4 groups (n=14). After sealant placement, the teeth were thermocycled (500 cycles; 5 degrees C, 37 degrees C(More)
OBJECTIVE To identify, in a group of 6-8-year-old schoolchildren, risk factors for dental caries increment in permanent dentition. METHODS Two hundred and six children from three different schools in Piracicaba, Brazil, were examined at baseline and after 7 years by the same two calibrated dentists. Data on dental caries (dmfs, DMFS, presence of initial(More)
OBJECTIVE To evaluate the reproducibility of caries detection and treatment planning among public health dentists and estimate the possible impact of their decisions on financial costs. RESEARCH DESIGN AND SETTINGS: Thirty nine dentists working in the public health service of Piracicaba, São Paulo, Brazil made a combined visual-radiographic caries(More)
OBJECTIVE Epidemiological studies have demonstrated that the prevalence and the severity of malocclusion have increased over the years. The aim of this study was to evaluate the relationship between malocclusions, such as open bite and crossbite, and behavioral, demographic and socioeconomic variables in a sample of 5-year-old children attending preschools.(More)
The aim of this study was to evaluate the relationship between malocclusion and self-perception of oral appearance/function, in 12/15-year-old Brazilian adolescents. The cluster sample consisted of 717 teenagers attending 24 urban public (n=611) and 5 rural public (n=107) schools in Maringá/PR. Malocclusion was measured using the Dental Aesthetic Index(More)
The main purpose of this study is to compare data from previous surveys to current prevalence rates of dental caries and dental fluorosis in eleven- and twelve-year-olds in a non-fluoridated Brazilian community (< 0.2 ppm F). This study also assesses the possible association between use of fluoride toothpaste and the prevalence of dental caries and dental(More)
