37. In vitro effect of amorphous calcium phosphate paste applied for extended periods of time on enamel remineralization
Abstract Dental applications based on the unique characteristics of amorphous calcium phosphate stabilized by casein phosphopeptides (CPP-ACP) have been proposed, as well as the improvement of its properties. Objectives: The objective of this study was to determine the ability of topically applied CPP-ACP from a commercial product to remineralize subsurface

38. Cymbopogon citratus essential oil: effect on polymicrobial caries-related biofilm with low cytotoxicity
Abstract The objective of this study was to evaluate the effects of Cymbopogon citratus essential oil and its main compound (citral) against primary dental colonizers and caries-related species. Chemical characterization of the essential oil was performed by gas chromatography/mass spectroscopy (GC/MS), and the main compound was determined. Antimicrobial act

39. Polymerization shrinkage stress of composite resins and resin cements – What do we need to know?
Abstract Polymerization shrinkage stress of resin-based materials have been related to several unwanted clinical consequences, such as enamel crack propagation, cusp deflection, marginal and internal gaps, and decreased bond strength. Despite the absence of strong evidence relating polymerization shrinkage to secondary caries or fracture of posterior teeth,

40. Effect of vegetable oils applied over acquired enamel pellicle on initial erosion
Abstract Objective The prevalence of dental erosion has been recently increasing, requiring new preventive and therapeutic approaches. Vegetable oils have been studied in preventive dentistry because they come from a natural, edible, low-cost, and worldwide accessible source. This study aimed to evaluate the protective effect of different vegetable oils, a

41. In situ effect of CPP-ACP chewing gum upon erosive enamel loss
Abstract Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is able to increase salivary calcium and phosphate levels at an acidic pH. Previous studies demonstrated that a CPP-ACP chewing gum was able to enhance the re-hardening of erosion lesions, but could not diminish enamel hardness loss. Therefore, there is no consensus regarding the effectiven

42. Influence of resin-modified glass ionomer and topical fluoride on levels of Streptococcus mutans in saliva and biofilm adjacent to metallic brackets
Abstract Decalcification of enamel during fixed orthodontic appliance treatment remains a problem. White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. The use of fluoride-containing orthodontic materials has shown inconclusive results on their ability to reduce decalcification. The aims of this investigation were to co

43. Role of Candida species from HIV infected children in enamel caries lesions: an in vitro study
Abstract Objectives This study analyzed the capacity of Candida spp. from dental biofilm of HIV infected (HIV+) children to demineralize primary molar enamel in vitro by Transversal Microhardness (TMH), Polarized Light Microscopy (PLM) and the quantity of calcium ions (Ca2+) released from the enamel. Material and Methods Candida spp. samples were isolated

44. Evaluation of Surface Roughness and Bacterial Adhesion on Tooth Enamel Irradiated With High Intensity Lasers
Resumo O objetivo foi avaliar a rugosidade superficial e adesão bacteriana no esmalte dental irradiado com lasers de alta intensidade, associados ou não a um verniz fluoretado. Oitenta fragmentos de esmalte foram igualmente divididos em 8 grupos (n= 10). O grupo 1 não recebeu tratamento e o grupo 2 recebeu aplicação de verniz fluoretado a 5%. Os outros

45. Clinical and radiographic sequelae to primary teeth affected by dental trauma: a 9-year retrospective study
Abstract This retrospective study aimed at determining the predicted risks of clinical and radiographic complications in primary teeth following traumatic dental injuries, according to injury type, severity and child’s age. Data were collected from records of children treated at a Dental Trauma Center in Brazil for nine years. Records of 576 children were

46. Effect of Fluoride Concentration on Reduction of Enamel Demineralization According to the Cariogenic Challenge
Resumo O fluoreto presente em dentifrícios de 1,100 µg/g é considerado efetivo no controle de cárie dental. No entanto, sob alto desafio cariogênico devido ao aumento da exposição ao açúcar, maior concentração de fluoreto (5.000 µg/g) poderia ser necessária para compensar o desequilíbrio no processo de cárie. Isso foi testado em um modelo de c

47. Analysis of the Early Stages and Evolution of Dental Enamel Erosion
Resumo O objetivo deste estudo foi avaliar os estágios iniciais e a evolução da erosão do esmalte dental causado pela exposição ao ácido clorídrico, simulando assim episódios de refluxo gastroesofágico, usando um microscópio de força atômica (AFM). Fragmentos de esmalte bovino planificados e polidos (4x4x2 mm) foram selecionados e exposto a 0,1

48. Fluoride rinse effect on retention of CaF2 formed on enamel/dentine by fluoride application
Abstract Calcium fluoride-like materials (“CaF2”) formed on dental surfaces after professional fluoride application are unstable in the oral environment but can be retained longer with a daily NaF mouthrinse. We tested the effect of twice daily 0.05% NaF rinses on the retention of “CaF2” formed on enamel and dentine after applying acidulated phosphat
