37. Influence of dialysis duration and parathyroid hormone on the clinical and radiographic oral conditions of pre-transplant patients with chronic kidney disease
AIM: To evaluate the oral conditions of patients with chronic kidney disease undergoing dialysis and to determine the influence of dialysis duration and bone metabolism on the prevalence and severity of the alterations found. METHODS: The simplified oral hygiene index (OHI-S), prevalence of dental caries (decayed, missing filled teeth index, DMFT), and the p

39. Estudo da cinética de ligação de cálcio e fluoreto à superfície de estreptococos e sua importância como reservatórios de íons no biofilme dental / Kinetics of calcium and fluoride binding to the surface of streptococci and the importance of these ions as mineral reservoirs in dental biofilm
The study of the retention of mineral ions in dental biofilm and their release to the biofilm fluid is important to understand the role of these reservoirs to interfere with the dental caries process. It is known that fluoride (F) is bound to the biofilm by interaction with calcium (Ca) ions. One type of reservoir formed is Ca-F bridging in bacteria surface

40. Ação do ultrassom na remoção do biofilme dos reservatórios de equipos odontológicos da Faculdade de Odontologia de Bauru / Action of ultrasound on biofilm removal of the dental units reservoir of water from Bauru School of Dentistry
Foram avaliados 25 reservatórios de água dos equipos odontológicos da Clínica de Dentística/Endodontia da FOB/USP com relação à presença de micro-organismos e a ação do ultrassom (US) na remoção do biofilme. Amostras de 10ml de água foram obtidas e alíquotas de 25l in natura e diluída até 10-4 foram semeadas pela técnica da gota nos meios:

41. Efetividade do uso de escova infantil com cerdas multinível associada à técnica de escovação anteroposterior na remoção de biofilme em primeiros molares permanentes em erupção / Effectiveness of using childrens toothbrush with multilevel filaments associated with anteroposterior toothbrushing in removing dental plaque from occlusal surfasse of erupting permanente molars
O presente trabalho objetivou: 1) comparar a efetividade da técnica de escovação anteroposterior com escovas de design modificado e cerdas multinível com a técnica de escovação transversal com escova infantil convencional de cerdas retas com, quanto à remoção de biofilme em superfícies oclusais de molares permanentes em erupção, em curto e longo

42. Avaliação da eficácia da desinfecção de instrumentos usados durante o período transoperatório do tratamento endodôntico / Evaluation of the desinfection efficacy of instruments used during the transoperatory period in endodontic treatment
This investigation aimed to evaluate the antimicrobial efficacy of disinfectant agents used to maintain the disinfection of endodontic instruments during the transoperatory period in endodontic treatment. The antimicrobial activity of disinfectants isopropyl alcohol, acetone and peracetic acid were evaluated upon planktonic micro-organisms by time kill assay

43. Risk indicators for tooth loss in adult workers
Tooth loss continues to be a prevalent condition in Brazilian adults and elderly individuals. The aim of this cross-sectional study, conducted among workers in a wholesale grocery chain in the State of São Paulo, was to identify risk indicators for tooth loss in adults. The presence of caries and periodontal status were examined in 387 adults aged 20-64 yea

44. The effect of iron on Streptococcus mutans biofilm and on enamel demineralization
Iron (Fe) may have an anticaries effect by specific inhibition of glycosyltransferase (GTF) enzymes of Streptococcus mutans, but this hypothesis has not yet been clarified. In this study, S. mutans biofilms were formed on blocks of bovine dental enamel of a predetermined surface hardness (SH). These biofilms were exposed eight times/day to 10% sucrose, and t

45. Calcium binding to S. mutans grown in the presence or absence of sucrose
Sucrose is the most cariogenic dietary carbohydrate because it is a substrate for insoluble extracellular polysaccharide (IEPS) production in dental biofilms, which can proportionally decrease bacterial density and, consequently, the number of biofilm calcium (Ca) binding sites. Ca bound to bacterial cell walls can be released into the biofilm fluid during a

46. Multi-species biofilm of Candida albicans and non-Candida albicans Candida species on acrylic substrate
OBJECTIVE: In polymicrobial biofilms bacteria extensively interact with Candida species, but the interaction among the different species of the Candida is yet to be completely evaluated. In the present study, the difference in biofilm formation ability of clinical isolates of four species of Candida in both single-species and multi-species combinations on th

47. Daily biofilm control and oral health: consensus on the epidemiological challenge - Latin American Advisory Panel
Our understanding of dental plaque biofilm has evolved since the nonspecific plaque hypothesis that considered plaque as a nonspecific mass of native microorganisms that, because of lack of oral hygiene, builds up in proportions great enough to overcome the host resistance threshold and affect the tooth structure and tooth supporting tissues. A great diversi

48. Análise microbiológica comparativa da ação de diferentes agentes descontaminantes sobre superfícies de titânio / Microbiological comparison of different decontaminant agents on rough and smooth titanium surfaces: microbiological analysis
Actually, the titanium implants are a successful option of treatment in Dentistry. However, failures are possible to occur due to surface exposition to oral environment immediately or lately after its implantation. The titanium implants surfaces can be infected by bacteria and its products similarly to dental roots surfaces. The contaminants turn the inflamm
