AIMS The aims of the study were: (i) to assess different clinical diagnostic methods of dental caries during epidemiological surveys; (ii) to determine which combinations of methods and diagnostic adjuncts show the best performances in epidemiological surveys when compared with examinations performed in a traditional dental setting (standard); (iii) to(More)
PURPOSE The purpose of this study was to compare results of 4 different methods of diagnosing dental caries in 12-year-old children by evaluating their influence on the DMFS index and analyzing the correlation of the radiographic exam with the clinical exam. METHODS The tools used were: 1) dental mirror; 2) dental mirror and dental explorer, both(More)
This study aimed to evaluate the impact of dental caries treatment on oral health-related quality of life (OHRQoL) among schoolchildren and the responsiveness of the Child Perceptions Questionnaire (CPQ8-10 ) instrument. Brazilian schoolchildren, 8-10 yr of age, were randomly selected and assigned to two groups--dental caries treatment (DCT) and caries-free(More)
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)
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)
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)
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)
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)
AIMS To compare caries prevalence and severity, as well as the disease distribution in the permanent dentition of 12-year-old schoolchildren in Bauru, Brazil, from 1976 to 2006. METHODS Probabilistic samples were obtained in six surveys, from 1976 to 2006, which were conducted by calibrated examiners, following the same protocol. For data analysis, the(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)
