13. Avaliação microbiológica in vivo de lesões de cárie profundas tratadas pela terapia fotodinâmica / In vivo microbiological analisys of deep carious lesions treated by photodynamic therapy
The traditional treatment of dentinal caries lesions has been based on the mechanical removal of all demineralized dentine, using hand or rotatory instruments. As an alternative to removal of the cariogenic organisms by drilling, the purpose of this study was to eliminate them through photosensitization promoted by irradiation with a low power laser associat

14. Avaliação da dentina de dentes decíduos submetidos à técnica de remoção parcial de tecido cariado
The aim of this study was to evaluate remaining carious dentin microhardness from deciduous teeth submitted to Indirect Pulp Treatment (IPT) and restored with self etching primer and composite, associated or not with calcium hydroxide capping. Deciduous molars treated with IPT and restored with Clearfil SE Bond ¿ Kuraray, Japan (CSE) and composite Filtek-Z2

15. Trigeminal postherpetic neuralgia: clinical and orofacial sensitivity evaluation / Neuralgia pós-herpética trigeminal: avaliações clínica e de sensibilidade orofacial
Postherpetic neuralgia is a complication after a varicella-zoster virus infection (VZV), affecting the trigeminal nerve in about 15-25% of the cases. This transversal study had the objective to evaluate the orofacial sensitivity and odontological characteristics of patients with trigeminal postherpetic neuralgia. The instruments used were: mechanical, therma

16. Influence of beverages routinely used in childrens diet on the enamel microhardness of primary teeth: an in vitro evaluation / Influência de bebidas ingeridas rotineiramente por crianças na microdureza do esmalte de dentes decíduos: avaliação in vitro
The aim of this study was to assess, in vitro, the influence of a lemon soft drink (Sprite®), an apple soya juice (Ades®) and a strawberry juice (Kapo®) routinely utilized in childrens diet on the superficial and deep microhardness of primary teeth enamel, as a function of the exposure time. Forty crowns of caries-free human primary incisors were included

17. AvaliaÃÃo histobacteriolÃgica da dentina apÃs a remoÃÃo do tecido cariado em prÃ-molares humanos in vitro
The present research had the objective to analyze qualitatively though histobacteriology, the remaining dentine of upper human premolars after removal of clinically decayed tissue, according to presence, location and distribution of microorganisms in dental tubules in different degrees of depth of carious lesion. It was selected representative histological b

18. Efeito da associação composito-materiais resilientes sobre a resistencia da união dentina/composito em modelos experimentais bi e tridimensionais
T he aim of this in vitro study was to assess the effect of different { resin composites and elastic layers on resin/dentin bond strength on " the buccal wall of Class I cavities. Ninety-six caries-free third molars were ground flat to expose the dentin surface under running water. Class I cavities (C-factor = 4.5, 4 mm mesial-distal, 3 mm buccal-lingual and

19. Molecular Analysis of Bacterial Species Associated with Childhood Caries
Although substantial epidemiologic evidence links Streptococcus mutans to caries, the pathobiology of caries may involve more complex communities of bacterial species. Molecular methods for bacterial identification and enumeration now make it possible to more precisely study the microbiota associated with dental caries. The purpose of this study was to compa

20. Cytokine Induction by Streptococcus mutans and Pulpal Pathogenesis
Chronic pulpal inflammation under caries appears to be elicited by bacterial antigens that diffuse into the pulp through dentinal tubules. This prompted the hypothesis that cytokines elicited by antigens from Streptococcus mutans, which frequently dominates shallow lesions, could play a major role in eliciting the initial T-cell response in the pulp. To test

21. Microbiological and microhardness evaluation of artificial enamel fissures worn intraorally by humans.
Devices simulating occlusal fissures were constructed from dental enamel and bonded to human maxillary molar teeth for 3 weeks. Facilitation of in vivo caries research in humans is the long-range goal for this model system. In the present investigation, microbial compositions of plaque in the fissural space of the model and natural fissural plaque from teeth

22. Functional Variation of the Antigen I/II Surface Protein in Streptococcus mutans and Streptococcus intermedius
Although Streptococcus intermedius and Streptococcus mutans are regarded as members of the commensal microflora of the body, S. intermedius is often associated with deep-seated purulent infections, whereas S. mutans is frequently associated with dental caries. In this study, we investigated the roles of the S. mutans and S. intermedius antigen I/II proteins
