Context: There is a possibility of dentinal crack formation in primary teeth after root canal preparation using rotary files.
Aims: To evaluate and compare the effect of ProTaper-Gold and Kedo-S rotary files on crack formation after root canal preparation in primary molars.
Settings And Design: A total of 120 freshly extracted mandibular primary molars (6-9 years) were randomly divided into three groups of 40 each: ProTaper-Gold, Kedo-S, and Hand H-files, respectively.
Introduction: Fracture of anterior teeth is the most frequent type of injury in the permanent dentition. Composite materials have made possible the use of adhesive materials and techniques, but storage of fragment in the media can enhance the bond strength. The purpose was to evaluate the influence of storage media and duration of the fragment in the media on the bond strength of the reattached fragment of teeth.
