introduction: the aim of this in vitro study was to evaluate the effect(s) of three canal lubricants i.e. sodium hypochlorite, rc-prep as the paste form of ethylenediaminetetraacetic acid (edta) and aqueous edta, on the occurrence/incidence of fracture, deformity and metal slivering of protaper rotary instruments. methods: a total of 120 mesial canals ( i.e. mesiobuccal and mesiolingual) of fir...

Objective: Klippel-Feil Syndrome (KFS) is a congenital syndrome that has short neck, fusion in at least 2 cervical vertebrae, and decrease neck movements the classic triad. KFS patients may have higher risk for mechanical spinal cord injury because of unstable segments. Patients should be examined extensively, since many anomalies accompany KFS. In current article, we aimed to present our cases...
