Fertile soil known as Amazonian dark earth is central to the debate over size and ecological impact of ancient human populations in Amazon. Dark typically associated with occupation, but it uncertain whether was created intentionally. may also be a substantial carbon sink, its spatial extent inventory are unknown. We demonstrate compositional similarities between modern document Indigenous practices that enrich soil, which we use propose model for formation earth. This comparison suggests...
Abstract The aim of this study was to evaluate the effect argon plasma on dentin surface after use 6% NaOCl. Sixty bovine incisors had their crowns removed, roots split, and segments planed. One hundred twenty cervical third were used. samples divided in two groups (n=60): Control group: immersed NaOCl, washed, dried then 17% EDTA, washed Argon treatment described for group, non-thermal applied 30 s. Ten evaluated by scanning electron microscopy each group. Other ten analyzed Fourier...
The aim of this study was to evaluate the remaining dentine/cementum thickness using Gates-Glidden burs in serial and crown-down sequences observe which two is safest for preparing mesial roots molars. Thirty-six left right human mandibular first molars were selected. Standard access cavities made initially explored with Flexofiles sizes 10 15 until tip visible at apex. teeth embedded a muffle specially developed PVC tube parallel metal rods its lid. Each tooth-block sectioned 3 mm apically...
The electronic method has been studied and improved aiming to add precision, speed reliability of the measurement technique determine exact location working length. Currently, root canal preparation recommends prior tooth length consequent perform instrumentation apical portion, a previous preflaring cervical middle thirds in various techniques. This procedure may provide reduction system impedance, leading read errors by apex locators. Objective: Investigate influence on accuracy measuring...
To describe the oral health status of patients with multiple myeloma and compare to a control group. The medical history studied subjects was obtained from records through interviews. Trained examiners evaluated mucosa, teeth, periodontium imaging aspects. dental by decayed, missing filled teeth index. presence bone lesions investigated cone beam computer tomography images jaws. most common mucosa features were paleness (31%) coated tongue (14.3%) in group (N = 42); (21.4%) fissured (10.7%)...
The aim of this retrospective cross-sectional study was to verify the association between salivary flow rates (SFR) and histopathologic aspects labial glands (LSG) in patients with rheumatoid arthritis (RA). Patients presenting rheumatologic diseases referred for oral evaluation were included if they had RA SFR measured LSG biopsy performed. excluded systemic conditions that affect or being treated hyposalivation. Cases without enough material analysis also excluded. Data collected through...
Resumo Introdução O tratamento de plasma é uma tecnologia eficaz que pode manter as propriedades internas dos materiais inalteradas após o tratamento, modificando apenas a superfície. Objetivo Avaliar efeito do oxigênio na dentina previamente exposta ao NaOCl 6%. Material e método Foram utilizados 60 incisivos bovinos. A coroa foi removida, raiz dividida faces planificadas, totalizando 120 segmentos referentes terço cervical. As amostras foram divididas em dois grupos: controle (imersa 6%,...
