PURPOSE The aim of this in vitro study was to assess the diagnostic performance of cone-beam computed tomography (CBCT) in the detection of secondary carious lesions under composite resin fillings applied to different types of cavities. MATERIALS AND METHODS Occlusal cavities (O) (n=18), occlusal cavities with mesial or distal component (MO/DO) (n=30), and mesial-occlusal-distal cavities (MOD...

Early childhood caries, a serious health problem among young children, can be prevented with effective intervention. The aim of this study was to evaluate the efficacy of oral health education and a fluoride varnish in the prevention of caries in children under the age of 3 years. For this single-blind randomized parallel group 1-year clinical trial in Shiraz, 300 children aged 12-24 months wit...

BACKGROUND It has been observed that the prevalence of dental caries among children has declined in the last decade in Germany. However, despite of these improvements there is still a proportion of children suffering from dental decay. AIMS The aims of this study were to evaluate if a social gradient in the prevalence of dental caries exists and, based on those findings, to develop a strategy...

OBJECTIVES To investigate the effectiveness of home visits advising mothers about healthy feeding practices during the first year of life on the occurrence of early childhood caries and severe early childhood caries at 4 years of age. METHODS We conducted a parallel randomized trial of mothers of single, full-term children with birthweight > or = 2500g in São Leopoldo, Brazil. The interventio...

This study evaluated the clinical performance of five single-step self-etch adhesive systems over a one-year follow-up period in 98 restorations. Independent evaluations were performed at baseline (one week), after three months, six months, and one year, by two trained examiners using the modified US Public Health Service rating criteria. Color match, marginal integrity, anatomical form, surfac...

The aim of this prospective, blind, and randomized clinical trial was to assess the effectiveness of repair of localized clinical defects in amalgam restorations that were initially scheduled for replacement. A cohort of 20 patients with 40 (Class I and Class II) amalgam restorations that presented one or more clinical features that deviated from the ideal (Bravo or Charlie) according to US Pub...

Oral diseases, including dental caries and periodontitis, are among the most prevalent diseases worldwide and develop as a consequence of a microbial dysbiosis. Several bacterial strains are being tested as potential oral health-promoting organisms, but usually they are species isolated from niches other than the site where they must exert its probiotic action, typically from fecal samples. We ...

The aim of this study was to evaluate the accuracy on the diagnosis of secondary caries-like lesions simulated on esthetic restorations of different materials, changing the incidence vertical angle (IVA) of the x-ray beam. Twenty human teeth received MOD inlay preparations. In the experimental group (n=10), a round cavity was made in the floor of the proximal box to simulate the caries-like les...

background: this study was aimed to compare the diagnostic accuracy and feasibility of cone beam computed tomography (cbct) with phosphor storage plate (psp) in detection of simulated occlusal secondary caries. materials and methods: in this in vitro descriptive-comparative study, a total of 80 slots of class i cavities were prepared on 80 extracted human premolars. then, 40 teeth were randomly...

BACKGROUND To investigate the role of geography (place of residence) as a moderator in the relationship between dental caries disease and treatment experience and dental fear in 16-year-olds living in Malaysia. METHODS A multi-stage-stratified sampling method was employed. Five hundred and three, 16-year-olds from 6 government secondary schools participated in this study. The questionnaire ex...
