13. Relation of Dental Anomalies with Occlusal Alterations in the Pediatric Patients
Abstract Objective: To identify the dental anomalies that can modify the occlusal characteristics and their distribution in these occlusal alterations in the skeletal patterns of children. Material and Methods: We analyzed charts, panoramic and periapical radiographs of children aged 5 to 12 years from 2009 to 2012. The facial pattern was evaluated through

15. Systemic Effects (Risks) of Water Fluoridation
Resumo Desde 1950, os benefícios e riscos do uso da água fluoretada têm sido debatidos mundialmente. No passado, foi considerado que o fluoreto ingerido sistemicamente exerceria seu efeito preventivo de cárie pela sua incorporação ao esmalte como fluorapatita, tornando o esmalte mais resistente ao processo de desenvolvimento de lesões de cárie; entre

16. Análise de interfaces de sistemas restauradores diretos em esmalte e em dentina humanos
RESUMO O presente estudo visou caracterizar a interface entre resina e substrato dentário submetida aos processos restauradores convencional e autocondicionante, levando a observar a presença de gaps e infiltração dos sistemas adesivos nos substratos dentários. A análise foi realizada em dois substratos dentários: o esmalte e a dentina. Seis dentes h�

17. Role of Candida albicans on enamel demineralization and on acidogenic potential of Streptococcus mutans in vitro biofilms
Abstract There is growing evidence that C. albicans is associated with dental caries, but its role on caries development needs to be better clarified. Objective: To evaluate at the hard tissue level the effect of C. albicans on the cariogenic potential of S. mutans biofilms focusing on the mineral profile of induced carious lesions. This study also aimed to

18. In Vitro Evaluation of Fluoride in Saliva After Topical Application of Professional Use Products
Abstract Objective: To evaluate in vitro the presence of fluoride in saliva after applying professional use products on the surface of dental enamel. Material and Methods: Experimental groups were composed by: Cariostatic 12% (CA), Fluoridated Varnish 5% (FV), Fluorine Acidulate Gel 1.23% (AG) and Fluorine Neutral Gel 2% (NG). Fluoridated dentifrice (FD) a

19. ORAL HEALTH PROMOTION IN PATIENTS WITH MORBID OBESITY AFTER GASTROPLASTY: A RANDOMIZED CLINICAL TRIAL
RESUMO Racional: A cirurgia bariátrica pode repercutir negativamente nas condições bucais. Objetivo: Avaliar o impacto de um programa educativo/preventivo em saúde bucal desenvolvido em pacientes submetidos à gastroplastia. Método: A amostra foi constituída por 109 pacientes aleatoriamente alocados em dois grupos: grupo de intervenção (GI), onde

20. Properties of zirconia-containing glass-ionomer cement
Resumo Cimentos de ionômero de vidro (CIVs) são utilizados como materiais restauradores dentários devido à sua capacidade de aderir quimicamente ao esmalte e à dentina, baixo coeficiente de expansão térmica e compatibilidade com estruturas dentárias. No entanto, esses materiais têm baixa resistência ao desgaste e fraturas. Neste trabalho, CIVs refo

21. Microhardness and Ultrastructure of Demineralized Gamma-Irradiated Human Enamel after Diode Laser (980 nm) and Fluoride Surface Treatment
Abstract Quality of life drastically diminished after radiotherapy due to radiation induced oral complications. Fluoride was found to be helpful in decreasing the incidence of radiation caries; however it has not led to elimination of dental caries. Thus, new techniques containing low fluoride concentration or not containing fluoride at all, as laser irradia

22. Explanation for the signs and symptoms of tooth eruption: mast cells
Resumo Para contribuir com a compreensão dos mecanismos relacionados à sintomatologia e aos sinais associados à erupção dentária, investigou-se a presença de mastócitos nos tecidos pericoronários na fase intraóssea (Grupo 1) e submucosa (Grupo 2), comparando-os entre si e com a mucosa bucal (Grupo 3). Em cada grupo, 14 espécimes foram analisados m

23. Effect of iontophoresis on fluoride uptake in enamel with artificial caries lesion
Abstract: Iontophoresis is a noninvasive technique, based on the application of a constant low-intensity electric current to facilitate the release of a variety of drugs, whether ionized or not, through biological membranes. The objective of this research was to evaluate the effect of iontophoresis using different electric current intensities on the uptake o

24. Microbial species associated with dental caries found in saliva and in situ after use of self-ligating and conventional brackets
Abstract Objectives Enamel demineralization is among the main topics of interest in the orthodontic field. Self-ligating brackets have been regarded as advantageous in this aspect. The aim of this study was to evaluate the break homeostasis in the oral environment and the levels of microorganisms associated with dental caries among the different types of b
