OBJECTIVES Little is known about the effect of Cervitec, a chlorhexidine-thymol varnish, on root caries. Our objective was to determine whether a 3-monthly application of Cervitec over 1 year would limit the progress of existing root caries lesions and reduce the incidence of dental root caries in a group of dentate institutionalized elderly, as a(More)
OBJECTIVES To determine the effect of chlorhexidine varnish on the prevention of caries in permanent first molars. METHODS Two groups of 6-7-year-old school children were followed up in a clinical trial, a group of 86 children whose teeth were treated with a chlorhexidine-thymol varnish (Cervitec) and a control group of 95 children. The varnish was(More)
BACKGROUND Bonding agents could be used as fissure sealants. This study compares the retention three fissure sealants (Delton, Delton Plus and Concise) and a filled dentin bonding system (Optibond Solo). METHODS. Fifty-six children aged 7-8 years received fissure sealants either in the four permanent first molars, in the four deciduous second molars, or in(More)
OBJECTIVE The aim of this study was to investigate whether genotypes of Streptococcus mutans strain can be detected as effectively in saliva samples as in plaque samples from buccal surfaces and occlusal surface fissures of permanent first molars. DESIGN The study included 20 school children aged 6-7 years who were positive for mutans streptococci.(More)
OBJECTIVES To determine whether the cessation for 3 years of a 24-month program of chlorhexidine-thymol varnish applications would affect caries incidence in the first permanent molars of a population of schoolchildren of middle and lower-middle socioeconomic level. METHODS Two groups of 6-7-year-old schoolchildren, randomized by school-class, were(More)
PURPOSE The objective of this study was to evaluate the effect of chlorhexidine-thymol varnish on the prevention of caries lesions in primary molars among schoolchildren ages 6 to 7 in relation to their previous experience with caries. METHODS Two groups of schoolchildren of lower-middle socioeconomic level were followed up in a clinical trial: one group(More)
Because dental fissures may serve as reservoirs for mutans streptococci, preventive measures should be taken to control microbial concentrations at these sites. This study estimated the influence that sealing permanent first molars would have on the levels of mutans streptococci and lactobacilli in saliva of healthy seven-year-old schoolchildren. Permanent(More)
