Diagnóstico e tratamento de lesões não cariosas: a visão do cirurgião-dentista ...
Ribeiro, Vanessa Savastano de Cerqueira Rêgo; Almeida, Emanoel Lima de; Leal, Isabelly de Carvalho; Bizerril, Davi OliveiraIntroduction: non-carious dental lesions present multifatorial etiology, and are characterized by irreversible wear on the tooth structure, without the involvement of microorganisms, and can be diagnosed as erosion (intrinsic or extrinsic), abfraction, attrition or abrasion. Objective: to analyze the knowledge of dental surgeons regarding the diagnosis and treatment of different types of non-carious dental lesi...
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 ...
Effect of green tea as a protective measure against dental erosion in coronary ...
Moraes, Maria Denise Rodrigues de; Carneiro, Jéssica Rodrigues Mendes; Passos, Vanara Florêncio; Santiago, Sérgio LimaThe aim of this study was to evaluate the effect of green tea as a protective measure on eroded dentin. Disks of human coronary dentin were selected based on surface hardness and randomly assigned to 3 groups (n = 10): DW - distilled water, CHX - 0.2% chlorhexidine digluconate, and GT - green tea. The disks were allowed to acquire pellicle for 2 hours and were then subjected to 3 cycles per day of demineralizat...
Photodynamic antimicrobial chemotherapy and ultraconservative caries removal li...
Melo, M.A.S.; Rolim, J.P.M.L.; Passos, Vanara Florêncio; Lima, R. A.; Zanin, I. C. J.; Codes, Bruna M.; Rocha, S. S.; Rodrigues, L. K. A.Background Ultraconservative removal of carious tissue is becoming increasingly highlighted for management of deep caries lesions, and combined with an antimicrobial photochemistry-based treatment modality (PACT), this approach can be enhanced favoring dental tissue repair and preservation. The aim was to investigate the effectiveness of PACT using a light emitting diode (LED) associated with a photosensitizer ...
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...
Fluoride releasing and enamel demineralization around orthodontic brackets by f...
Melo, Mary A. S.; Morais, Weslanny A.; Passos, Vanara Florêncio; Lima, Juliana P. M.; Rodrigues, Lidiany K. A.Introduction Fluoride-containing materials have been suggested to control enamel demineralization around orthodontic brackets during the treatment with fixed appliances. The improvement of their properties has been made through innovations, such as the application of nanotechnology by incorporation of nanofillers. Objective This in vitro study evaluated the capacity of fluoride releasing and enamel demineraliza...
Effects of diode laser therapy and stannous fluoride on dentin resistance under...
Passos, Vanara Florêncio; Melo, Mary Anne S.; Silva, Francisco F.C.; Rodrigues, Lidiany Karla A.; Santiago, Sérgio L.Objective: This in vitro study aimed to evaluate the effect of a low intensity diode laser (k = 808 nm; 60 J/cm2) associated with stannous fluoride on the inhibition of dentin erosion by assessing percentage of superficial hardness loss (%SHL) and calcium release into the acid solution. Materials and methods: Human root dentin slabs were assigned to eight groups (n = 10), according to treatments (control, stann...
Methodologies to analyze the micromorphological alterations of enamel subjected...
Passos, Vanara Florêncio; Santiago, Sérgio LimaThe incidence of caries has declined; however, other dental lesions such as tooth wear are becoming increasingly important. Dental wear is a multifactorial process that may encompass erosion, abrasion, and combinations thereof. Therefore, various methodologies have been applied to evaluate the loss of dental hard tissue and the surface-softened zone in enamel induced by abrasive and erosive challenges. In this ...
Comparison of methods for quantifying dental wear caused by erosion and abrasion
Passos, Vanara Florêncio; Melo, Mary A. S.; Vasconcelos, Andréa Araújo; Rodrigues, Lidiany K.A.; Santiago, Sérgio L.Various methods have been applied to evaluate the effect of erosion and abrasion. So, the aim of this study was to check the applicability of stylus profilometry (SP), surface hardness (SH) and focus-variation 3D microscopy (FVM) to the analysis of human enamel and dentin subjected to erosion/abrasion. The samples were randomly allocated into four groups (n 5 10): G1-enamel/erosion, G2-enamel/erosion plus abras...
Dentin erosion by whitening mouthwash associated to toothbrushing abrasion : a ...
Lima, Juliana P.M.; Melo, Mary A. S.; Passos, Vanara Florêncio; Braga, Cícero L. N.; Rodrigues, Lidiany K. A.; Santiago, Sérgio L.The aim of this study was to determine the erosive potential of hydrogen peroxide (HP) containing mouthwash on dentin assessed by Focus variation three-dimensional (3D) microscopy. Twenty dentin slabs were selected and randomly allocated into two groups (n 5 10): DW—Distilled water (pH 5 7.27) and HP—1.5% (pH 5 3.78). Each specimen was cyclically demineralized (4 3 60 s/day, 10 days) with HP or DWand brushed 33...
