Quantification and gene expression of Lactobacillus casei group species associa...
Reis, Ana Catarina Martins; Bezerra, Daniela da Silva; Hart-Chu, Erika Nikitza Shiauha; Stipp, Rafael Nóbrega; Guedes, Sarah Florindo de FigueiredoBackground Considering that the Lactobacillus casei group is strongly associated with caries progression, the use of lactobacilli as probiotics must be balanced due to their possible involvement in dental caries. Objective This study aimed to detect and quantify L. paracasei, L. rhamnosus, and L. casei group species in the active and arrested dentinal lesions of preschoolers. It also aimed to determine the expr...
Sources of stress, psychological well-being and health among dental students: a...
Muniz, Mariana Fernandes; Muniz, Francisco Wilker Mustafa Gomes; Rodrigues, Lidiany Karla Azevedo; Oliveira, Marcelo Bruno Lemos; Barros, Isadora DanielThe aim of this study was to evaluate psychological well-being, overall health, and sources of stress among dental students from four Doctor of Dental Surgery (DDS) programs, comparing the preclinical and clinical phases and sexes. Three instruments were applied: Dental Environment Stress (DES), Psychological General Well-Being Index (PGWB) and Health Survey (SF-36), answered by 203 students, with 75 (37%) in t...

Effects of bleaching agents containing fluoride and calcium on human enamel
Gobbo, Vanessa Cavalli; Rodrigues, Lidiany Karla Azevedo; Paes-Leme, Adriana Franco; Brancalion, Marcel Luis; Arruda, Marco Aurelio ZezziMade available in DSpace on 2019-09-12T16:57:13Z (GMT). No. of bitstreams: 0 Previous issue date: 2010; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Objective: Since little is known about the effects of carbamide peroxide (CP) containing fluoride (F) or calcium (Ca), this study evaluated the effects of experimental and commercially available bleaching agents, with or without F and Ca, on ename...
Cellular differentiation, bioactive and mechanicalproperties of experimental li...
Sauro, Salvatore; Babbar, Ashvin; Gharibi, Borzo; Feitosa, Victor Pinheiro; Carvalho, Ricardo Marins; Rodrigues, Lidiany Karla Azevedo; Banerjee, AvijitObjective. Materials for pulp protection should have therapeutic properties in order to stim-ulate remineralization and pulp reparative processes. The aim of this study was to evaluatethe mechanical properties, biocompatibility, cell differentiation and bioactivity of experi-mental light-curable resin-based materials containing bioactive micro-fillers.Methods. Four calcium-phosphosilicate micro-fillers were pre...
Active compounds and derivatives of camellia sinensis responding to erosive att...
Passos, Vanara Florêncio; Melo, Mary Anne Sampaio de; Lima, Juliana Paiva Marques; MarçaL, Felipe Franco; Costa, Cecília Atem Gonçalves de AraújoThis research explored the potential of Camellia sinensis-derived teas and active compounds to be used as treatments to prevent dentin wear. Human root dentin slabs were randomly assigned to 5 groups (n = 10) as follows: distilled water (DW, control), epigallocatechin-3-gallate (EGCG), theaflavin gallate derivatives (TF), commercial green tea (GT), and commercial black tea (BT). The samples were submitted to a ...
Effectiveness of different removal methods of artificially demineralized dentin
Ferraz, Camila; Thé, Patrícia Lima; Mendonça, Juliano Sartori; Fernandes, Carlos Augusto; Rodrigues, Lidiany Karla Azevedo; Yamauti, MonicaObjective: This study aimed to evaluate the effectiveness of different mechanical methods for the removal of demineralized dentin. Methods: Healthy human third molars were prepared in such a way that the flat occlusal surfaces of the dentin were exposed and longitudinally sectioned in a vestibular-lingual direction. One section of each tooth was submitted to the pH-cycling model, while the other section was kep...
The Influence of dentin demineralization on morphological features of cavities ...
Melo, Mary Anne Sampaio; Lima, Juliana Paiva Marques; Passos, Vanara Florêncio; Rodrigues, Lidiany Karla AzevedoObjective: The purpose of this study was to evaluate the influence of erbium-doped: yttrium-aluminum-garnet (Er:YAG) laser parameters and different degrees of demineralization on morphological features, diameter, and depth of prepared cavities. Background data: Minimally invasive dentin caries removal has been recommended. Ablation of deep caries lesions using Er:YAG laser should preserve remaining demineralize...
Effect of oxalic acid pre-treatment in restorations of non-carious cervical les...
Souza, André Mattos Brito de; Colares, Regina Cláudia Ramos; Mendonça, Juliano Sartori; Rodrigues, Lidiany Karla Azevedo; Santiago, Sérgio LimaNon-carious cervical lesions are usually associated with dentin hypersensitivity. The use of oxalic acid in restorations of these lesions could be beneficial in relieving pain. Aims: To evaluate the use of oxalic acid in restorations of non-carious cervical lesions. Settings and Design: A randomized clinical trial. Subjects and Methods: One operator placed 90 restorations in 20 volunteers of both sexes, with at...
Effect of chlorhexidine on the bond strength of a self-etch adhesive system to ...
Melo, Mary Anne Sampaio de; Goes, Diego da Costa; Moraes, Maria Denise Rodrigues de; Santiago, Sérgio Lima; Rodrigues, Lidiany Karla AzevedoThis study evaluated the effect of a 2% chlorhexidine-based disinfectant (CHX) on the short-term resin-dentin bond strength of a self-etch adhesive system to human dentin with different mineral contents. Dentinal mineralization was tested at 4 levels (sound, and after 2, 4, or 8 days of demineralization-remineralization cycles) and disinfectant at 2 levels [deionized water (DW, negative control) and CHX].
