25. Hand and ultrasonic instrumentation for orthograde root canal treatment of permanent teeth
Root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. Removal of the necrotic tissue remnants and cleaning and shaping of the root canal are important phases of root canal treatment. Treatment options include the use of hand and rotary instruments and

28. âO uso da clorexidina intracanal em molares decÃduos com necrose pulpar â estudo clÃnico e microbiolÃgicoâ / Intracanal chlorhexidine in primary molars with pulp necrosis- a clinical and microbiological study
The success of endodontic treatment depends on many factors, and the reduction or elimination of bacterial infection is the most important one. Therefore, the use of substances that act against these microorganisms and their products becomes an important stage in treatment. The aim of this in vivo split-mouth study was to compare the efficacy of a 1% chlorhe

30. Identificação microbiologica em dentes com necrose pulpar e abscessos periapicais e a suscetibilidade antimicrobiana de algumas bacterias anaerobias isoladas / Microbial identification in teeth with pulpar necrosis and periapical abscess and the antimicrobial susceptibility of some anaerobic bacteria
The aim of the present study was to analyze the endodontic microbiota of teeth with pulp necrosis and spontaneous pain; detect the presence of enterococci, fungi and enteric bacteria in saliva and root canals; and, to determine, in vitro the antimicrobial sensitivity of anaerobic isolates by E-test and _-lactamasis production. Thirty samples were collected f

31. Identificação da microbiota das lesões endo-periodontais por cultura e PCR e sua suscetibilidade ao preparo quimico-mecanico e a medicações intracanais entre sessões de atendimento / Identification of endodontic-periodontal lesions microbiota by culture and PCR and their susceptibility to chemo-mechanical preparation and intracanal dressings between appointments
The aims of this study were to investigate the microbiota of root canals (RC) and periodontal pockets (PP) from teeth with pulp necrosis, periapical lesion, gingival bleeding and periodontal pockets by culture and PCR; to verify the ability of chemo-mechanical preparation (CMP) and intracanal dressings (2% chorhexidine, calcium hydroxide and association of b
