This study analyzed comparatively, by confocal laser scanning microscopy (CLSM), the depth of caries-like lesions produced by biological and chemical artificial models in permanent and primary dentin. Six primary molars and six premolars were used. The occlusal enamel was removed and a nail polish layer was applied on the specimens, except for a 4 x 2 mm area on dentin surface. Half of specimen...

BACKGROUND: The decline in caries has slowed and this may be indicative of variation in the susceptibility of differing teeth to caries. This study tests the hypothesis that in children, there are groups of tooth sites that exhibit differences in caries susceptibility. METHODS: Probit analysis of caries data collected from a 4-year longitudinal study of 20,000 schoolchildren aged between 5 and ...

OBJECTIVE To document changes in disease experience among Taranaki adolescents in order to enhance understanding of the natural history of dental caries in a key developmental period. METHOD A random sample of 430 adolescents first examined in 2003 at age 13 were re-examined at age 16, when 255 (59.3%) took part. Dental caries status (in the permanent dentition) was recorded at each age by a ...

This paper describes the results of a cross-sectional study conducted with a randomized sample of 447 low-income children between 2.5 and 4 years of age selected from the files of a health institution in Medellin, Colombia. The patients were examined in 2007 using the modified criteria of the International Caries Detection and Assessment System (ICDAS); the first caries code was not used. Clini...

This paper summarizes current trends in the clinical diagnosis of occlusal caries in response to the RTI/UNC review and reflects the dilemma felt by many dentists who understand the difficulty in accurately assessing the extent and activity of pit and fissure caries in many of their patients. They are unsure if they should be aggressive in instrumenting suspicious lesions and provide small rest...

background: managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. the present study evaluated the histological status of pulp tissues extracted from primary second molar with caries involvement. histological findings are correlated with clinical and radiographic assessment. materials and methods: simple experimental stu...

While sealants are more effective than fluoride varnish in reducing the development of new carious lesions on occlusal surfaces, and a course of treatment requires fewer clinical visits, they are more expensive per application. This analysis assessed which treatment is more cost-effective. We estimate the costs of sealants and fluoride varnish over a 4-year period in a school-based setting, and...
