To evaluate the activity of various root canal irrigants on bovine pulp tissue.The tested were: 0.5, 1.0 and 2.5% sodium hypochlorite; 2% aqueous solution chlorhexidine digluconate; digluconate gel (Natrosol); distilled water as control. Bovine fragments were weighed placed in contact with 20 mL each substance a centrifuge at 150 r.p.m. until total dissolution. Dissolution speed was calculated by dividing weight dissolution time. Statistical analysis performed using Kruskal-Wallis...
Summary Background The site and distribution of inflammation in the airways asthmatic patients has been largely investigated. Inflammatory cells are distributed both large small asthma. It demonstrated that distal lung asthma may significantly contribute to pathophysiology disease. upper have also implicated overall inflammation. Although it is now accepted not restricted intrapulmonary asthma, little known about cell other compartments their relation airways. Objective We aimed map...
To evaluate, using micro-computed tomography, the preparation of long-oval root canals a single reciprocating system versus multiple-file rotary system.Distal thirty mandibular molars were selected and randomly assigned to one two instrument groups (n = 15): Reciproc 40 (VDW, Munich, Germany) or BioRaCe (FKG Dentaire, La Chaux-de-Fonds, Switzerland). The teeth scanned before after canal by SkyScan 1172 tomography scanner at 11-μm resolution. Morphometric variations measured volume increases...
Abstract Aim To compare the shaping ability of four instrumentation systems in curved molar root canals, using computerized microtomography (micro‐ CT ). Methodology Forty mesial roots mandibular molars were submitted first to radiographic examination determine their curvature and then a micro‐ scan analyse other initial morphological characteristics. The specimens distributed into experimental groups, according endodontic system used ( n = 10): Group R, Reciproc; PTN , ProTaper Next; WOG...
The aim of this study was to assess the effectiveness five different solvents: xylol, eucalyptol, halothane, chloroform and orange oil on softening gutta-percha in simulated root canals. One drop solvent placed into a reservoir made canal whose channel previously instrumented filled with N-Rickert sealer. After 5 min, evaluated for each by penetration spreader while applying force 442 Instron apparatus reach depth mm. results were analyzed statistically Kruskal-Wallis test. Xylol better than...
The aim of this study was to compare two methods assessing apical transportation in curved canals after rotary instrumentation, namely, cross-sections and micro-computed tomography (µCT). Thirty mandibular molars were divided into groups prepared according the requirements each method. In G1 (cross-sections), teeth embedded resin blocks sectioned at 2.0, 3.5, 5.0 mm from anatomic apex. Pre- postoperative sections photographed analyzed. G2 (µCT), a rubber-base impression material scanned...
A trajetória das mulheres na ciência é marcada por descobertas e estudos científicos fundamentais para o avanço da ciência, além disso, sua participação envolvimento nessa área, também acompanhada muita desigualdade de gênero desvalorização suas pesquisas. Diante esse projeto desenvolvido dentro do Programa Institucional Bolsas Extensão (PIBEX), teve como objetivo promover a conscientização sobre papel fundamental através divulgação grandes figuras inspiradoras, desconstruir estereótipos...
Abstract Bioceramic materials have been introduced in dentistry due to their physical, chemical, and biological properties, which are considered advanced clinical practice. According the manufacturer, CIMMO DTA bioceramic restorative cement is a was recently at low cost compared other materials. However, no studies evaluated effect of on human dental pulp cells (HDPC) activated with lipopolysaccharide (LPS). Therefore, this study aimed evaluate cytotoxicity osteo/odontogenic differentiation...
Root canal preparation may damage NiTi instruments resulting in wear and deformation. The aim of this study was to make a comparative evaluation the surface topography cervical third four different rotary systems, before after being used twelve times, 1.440 resin blocks with simulated root canals standardized 45° curvatures, analyzed by atomic force microscopy AFM. were divided into groups prepared according manufacturers recommendations: Group 1--K3®; 2--Protaper Universal®; 3--Twisted...
