1. Effectiveness of XP-Endo Finisher in the reduction of bacterial load in oval-shaped root canals
Abstract: This study investigated the effectiveness of XP-Endo Finisher (XPF) associated with XP-Endo Shaper (XPS) or Reciproc Blue (RB) files in reducing bacterial load in oval-shaped root canals (RC) during chemomechanical preparation (CMP) using 0.9% saline solution (NaCl) or 2.5% sodium hypochlorite (NaOCl). Eighty mandibular incisors with single oval-sh

2. Experimental evaluation of cyclic fatigue resistance of four different nickel-titanium instruments after immersion in sodium hypochlorite and/or sterilization
NiTi instruments have a high risk of separation due to torsional or flexural fatigue (cyclic fatigue). Chemomechanical preparation, cleaning procedures, chemical disinfection and sterilization cause the corrosion of endodontic instruments that may weaken the fracture resistance of the instruments. Objective To assess the effects of NaOCl immersion and auto

3. Influence of Hero Apical instruments on cleaning ovoid-shaped root canals
The cleaning capacity of Hero 642 nickel-titanium files, complemented by the Hero Apical instruments in flattened roots, was determined by histological analysis, considering the area of action of the instruments on the coronal walls and the presence of remaining debris. Twenty-four single-canal, human mandibular incisors were divided into three groups and pr

4. Influence of protaper finishing files and sodium hypochlorite on cleaning and shaping of mandibuldar central incisors - a histological analysis
OBJECTIVE: This study investigated the influence of the last apical instrument of the ProTaper system with and without 2.5% sodium hypochlorite for cleaning mandibular central incisors. MATERIAL AND METHODS: Thirty two mandibular central incisors were divided into six study groups: Group I - F1 instrument with 2.5% sodium hypochlorite; Group II - F1 and F2 w

5. AVALIAÇÃO, IN VITRO, DE PREPAROS QUÍMICO-MECÂNICO DE CANAIS RADICULARES QUANTO AO DESVIO, LIMPEZA, MODELAGEM DO TERÇO APICAL E DEFORMAÇÕES MECÂNICAS DE INSTRUMENTOS DE NÍQUEL-TITÂNIO E AÇO INOXIDÁVEL
This study had as main objective to evaluate the apical third of root canals within cleaning, apical displacement, shaping after root canals preparations with both rotatory and alternating mechanized systems associated or not. It still had as objective, the detection of deformations and separations of endodontic flares used in the study. A total of 45 upper

6. Análise da limpeza dentinária em canais radiculares preparados com um sistema rotatório e diferentes substâncias químicas / Analysis of the cleaning of root canal prepared with one rotary instruments system and different chemical substances
The development of nickel-titanium (NiTi) endodontic instruments results in more quickness during the root canal shaping phase that induce us to discuss if really would be the chemical substances are having opportunities to act properly, considering that the time of action of the same was significantly reduced. The object of this research was evaluate, using

7. Avaliação da limpeza das limas endodônticas, antes de sua reutilização na instrumentação de canais radiculares
Este trabalho teve por objetivo avaliar o estado de limpeza das limas endodônticas dos alunos de graduação bem como o conhecimento dos mesmos quanto aos cuidados necessários para a sua reutilização. Avaliou-se também três métodos de limpeza das limas frente aos tratamentos endodônticos com e sem vitalidade e retratamentos. Na primeira etapa do estu
