BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...

i ntroduction: the purpose of this in vitro study was to compare the canal transportation and centering ability of twisted file (tf) to that of reciproc system. methods and materials: forty noncalcified roots with mature apices, minimum length of 19 mm and an apical curvature of 15-30 degrees (according to schneider’s method), from freshly extracted mandibular and maxillary teeth, were selected...

The objective of the present study was to assess the effectiveness of reciprocating instrumentation in disinfecting oval-shaped root canals infected with Enterococcus faecalis. Forty-five human lower premolars were infected with a culture of E. faecalis (ATCC 29212) for 28 days. Five other teeth that were neither contaminated nor instrumented were used as controls. The 45 specimens were divided...

Introdução: A limpeza e modelagem, são etapas de extrema importância na instrumentação dos canais radiculares para que se tenha um tratamento endodôntico feito com excelência. Com o objetivo otimizar tempo trabalho apresentar material qualidade, foram criadas as limas NiTi (Niquel Titânio) asseguram sucesso. Os blocos acrílico usados uma padronização simulados. Objetivo: Esta pesquisa teve como...

A utilização de ligas em níquel-titânio revolucionou a endodontia e fez com que os tratamentos endodônticos se tornassem ainda mais eficazes por provocarem menos alterações na antomia original do canal radicular. Com o surgimento novos sistemas automatizados como Reciproc® (VDW GmbH, Munique, Alemanha) Wave One® (Dentsply-Mailefer, Ballaigues, Suíça), esses logo ficaram conhecidos no mercado ap...

introduction: the aim of this in vitro study was to evaluate the effects of establishing glide path on the centering ability and preparation time of two single-file reciprocating systems in mesial root canals of mandibular molars. methods and materials: sixty extracted mandibular molars with curvatures of 25-39 degrees and separate foramina for the mesiobuccal and mesiolingual canals, were divi...

objectives: during root canal preparation, apical extrusion of debris can cause inflammation, flare-ups, and delayed healing. therefore, instrumentation techniques that cause the least extrusion of debris are desirable. this study aimed to compare apical extrusion of debris by five single-file, full-sequence rotary and reciprocating systems. materials and methods: one hundred twenty human mandi...
