A Comparison Of Endodontic Root-End Filling Techniques: A Micro-Computed Tomography Analysis, Leslie P. Wolford

Graduate Theses, Dissertations, and Problem Reports

Introduction:

Researchers have compared the differences between hand compaction of root-end filling bioceramics with compaction of these materials by hand followed by ultrasonic activation (hand/ultrasonic compaction). Additionally, most of these researchers did not utilize Micro-Computed Tomography (Micro-CT) analysis. The purpose of this study is to evaluate total porosity volume of three different bioceramics when compacted by hand alone versus hand/ultrasonic compaction using Micro-CT Analysis.

Materials and methods:

Seventy-two human maxillary central incisors were selected for the study. All were subjected to orthograde endodontic treatment followed by root tip resection 3-mm from the apex at a 90° to the long axis …
