Background. This study evaluated the ability of Kryptonite bone cement in sealing retrograde cavities. Methods. The root canals of one hundred extracted human maxillary incisor teeth were instrumented up to master apical file #40 using Mtwo rotary system and obturated with gutta-percha and AHPlus sealer by cold lateral compaction method. The specimens were assigned to one control group and four...

Background: The aim of the present study was to evaluate canal transportation and centering ability ProTaper, HeroShaper two Ni-Ti rotary systems developed for retreatment (ProTaperRetreatment R-Endo). Materials Methods: One hundred twenty mesial canals mandibular molars with curvatures between 30-40 degrees radii 4-9 mm were embedded in a modified muffle system. teeth randomly divided into 8 g...

Jarum patah di dalam saluran akar dapat disebabkan oleh penggunakan instrumen jarum endodontik yang tidak tepat saat melakulan preparasi biomekanis. Beberapa hal menyebabkan patahnya adalah teknik tepat, kekuatan fisik sudah melebihi limit batas waktu pemakaian, akses adekuat, anatomi rumit, dan cacat pabrik. Terdapat tiga pendekatan penanggulangan yaitu, membiarkannya tempat (leave in situ), m...

The objective of this study is to assess the cytotoxic effects of substances leached from five endodontic sealers in time periods of 0 and 24 hours on NIH 3T3 fibroblasts. It was used a medium conditioned by the sealers, subdivided in six groups namely: Control (fresh cell culture medium); SimpliFill (Discus Dental, Culver City, Calif) : EndoREZ ® (Utradent Products, Inc); EPIPHANY® (Pentron Cl...

Introduction: Optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. So, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. Materials and Methods: In this in vitro study, six endodo...
