1. 3-year survival rates of retained composite resin and ART sealants using two assessment criteria
Abstract The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period

2. Análise comparativa in vivo da detecção de lesões de cárie oclusal e proximal por meio de exame visual (ICDAS), exame radiográfico e transiluminação por fibra ótica (FOTI) / In vivo comparative analysis of aproximal and occlusal caries lesions detection using visual examination (ICDAS), radiograph examination and fiber optic transillumination (FOTI)
The aim of this in vivo study was to assess the ICDAS visual method, combined ICDAS/fiber optic transillumination and bite wing radiographs. A total of 2,279 pits and fissures in upper incisors, pre-molars and molars permanent surfaces and 272 primary molars surfaces in 72 patients (aged 8 to 18 years-old) were assessed by an trained examiner. The seven scor

3. Avaliação in vitro e in situ da eficácia de diferentes lasers no aumento da resistência ácida do esmalte em regiões de sulcos e fissuras / In vitro and in situ assessment of lasers to increase enamel acid resistance on the pits and fissures surface.
The aim of this study was to assess in vitro and in situ the lasers Er:YAG, Nd:YAG e CO2 in preventing enamel demineralization on the pits and fissures surface. For the in vitro study 45 occlusal enamel blocks were randomly divided into 3 groups in according with the treatment: G1 - Er:YAG; G2 - Nd:YAG; G3 - CO2. Treatments were made only on a half of the sp

4. The ART approach: clinical aspects reviewed
The success of ART as a caries management approach is supported by more than 20 years of scientific evidence. ART follows the contemporary concepts of modern cariology and restorative dentistry. It challenges treatment concepts such as step-wise excavation and the need for complete removal of affected dentine. The ART approach so far has mainly used high-vis

5. In vivo reproducibility and correlation of visual and laser fluorescence methods for the detection of pits and fissures with discoloration in primary molars / Reprodutibilidade e correlação in vivo dos métodos visuais e de fluorescência a laser na detecção de descolorações em sulcos e fossetas oclusais de molares decíduos
Aiming at developing an in vivo study of the reproducibility and correlation of two visual indexes (Ekstrand et al. (1998) ? E and Nyvad; Machiulskiene and Baelum (1999) ? N) and the measures of laser fluorescence (DIAGNOdent®,KaVo - DD) for the detection of decolorised pits and fissures, a single trained examiner, after the free and aware consent of 28 pat

6. Association of tetra-amelia, ectodermal dysplasia, hypoplastic lacrimal ducts and sacs opening towards the exterior, peculiar face, and developmental retardation.
A male child with tetra-amelia, hypotrichosis, upward slanting palpebral fissures, lack of lacrimal openings, hypoplastic lacrimal ducts and sacs opening towards the exterior, prominent and bulbous nose, large downturned mouth, high narrow palate, bilateral preauricular pits, sacral dimple, bilateral undescended testes, and developmental retardation is repor

7. Relationship between host age and susceptibility to oral colonization by Actinomyces viscosus in Sprague-Dawley rats.
The colonization of Actinomyces viscosus strain Ny-1R on the molar teeth of conventional and ex-germfree rats of various ages fed either a high-sucrose diet, a high-glucose diet, or laboratory chow was studied. Conventional rats directly after weaning and up to 30 days of age are less susceptible to experimental infection by strain Ny-1R than are older rats

8. Isolation and immunobiological classification of Streptococcus sanguis from human tooth surfaces.
A total of 113 pure cultures of Streptococcus sanguis were obtained from dental plaque samples of 64 subjects. All isolates synthesized glucan from sucrose, elaborated peroxide, and were alpha-hemolytic. Two biotypes and four serotypes were differentiated within the species. Biotype A (95 isolates) fermented salicin and inulin and hydrolyzed arginine and esc
