25. Endodontic irrigation effect on microhardness, morphology and roughness in primary and permanent teeth / Influencia da irrigação endodontica sobre a microdureza, morfologia e rugosidade de dentes deciduos e permanentes
Irrigation solutions, endodontic auxiliary chemical substance, and chelating agents used on root canal treatment might yield changes in the chemical composition and physical properties of dentin surface, and affect its interaction with materials used for coronal sealing. Thus, studies are required to select a suitable chemical agent, which has minimal effect

26. Evaluation of the interaction between sodium hypochlorite and chlorhexidine gel on the root dentin surface / Avaliação da reação do hipoclorito de sódio e do gel de clorexidina na superfície do canal radicular
When combined in the interior of the canal, sodium hypochlorite and chlorhexidine form an insoluble product. The aim of this study was to evaluate the consequences of the use of the hipoclorito of sodium 1% pH 9 (NaOCl) as substance during prepare and gel of clorexidina 2% (CHX) as intracanal medication in different conditions, using environmental scanning e

27. Cleaning ability of chlorhexidine gel and sodium hypochlorite associated or not with EDTA as root canal irrigants: a scanning electron microscopy study
The aim of this study was to evaluate the cleaning efficacy of 2% chlorhexidine gluconate gel (CHX) compared to 2.5% sodium hypochlorite solution (NaOCl) associated or not with 17% EDTA used as irrigants during the biomechanical preparation. Fifty freshly extracted single-rooted human teeth with complete apex formation were randomly divided into five groups:

31. Avaliação da efetividade do hipoclorito de sodio 5,25% e clorexidina gel 2% na remoção de pre-dentina em areas não instrumentadas de canais radiculares de incisivos inferiores : estudo in vitro / An in vitro evaluation of the effectivity of 5.25% sodium hypochlorite and 2% chlorherixidine gel in removing predentin from non instrumented areas of lower incisors root canals
The aim of this study was to evaluate the predentin removal capacity of two substances used as irrigating substances in Endodontics ? 5.25% sodium hypochlorite and 2% chlorhexidine gel - on the apical, middle and cervical thirds from human mandibular incisors with vital pulps and mesio-distal flattened root canals. During the biomechanical preparation, volum

32. Influencia de irrigantes endodonticos na resistencia de união de um adesivo autocondicionante a dentina da camara pulpar
Chemical irrigants and medications used in endodontic therapy may have an adverse effect on bonding to pulp chamber dentin. The aim of this study was to evaluate in vitro the influence of endodontic irrigants on the bond strength of a self etching adhesive system to bovine teeth pulp chamber dentin. Seventy crowns of bovine mandibular incisors were cut to ex

33. Cytotoxicity analysis of EDTA and citric acid applied on murine resident macrophages culture. / "Análise da citotoxicidade do EDTA e do ácido cítrico aplicados em cultura de macrófagos peritoneais residentes"
The present study evaluated in vitro cytotoxic effects of 17% EDTA and 15% citric acid in murine resident macrophages using MTT assay. After anesthesia and sacrifice of thirty two Swiss male mice, it had processed the peritoneal cellular exudates by fresh culture medium injection and aspiration in peritoneal animals cavities. The peritoneal exudates were com

34. Estudo in vitro da atividade antimicrobiana imediata e mediata da clorexidina gel 2% usada como irrigante endodontico contra Enterococcus faecalis
The initiation and perpetuation of pulpal and periapical disease occur due to the presence of bacteria and their degradatory by products in the root canal. The host defense cells are unable to reach bacteria harbored in the root canal system thus, the root canal therapy must be performed combining mechanical procedures and chemical substances. For that reaso
