Ultrasonic Versus Hand Filing Of The Human Root Canal System, Howard W. Scholz Jr.
Ultrasonic Versus Hand Filing Of The Human Root Canal System, Howard W. Scholz Jr.
Loma Linda University Electronic Theses, Dissertations & Projects
A comparison was made of ultrasonic filing versus hand filing using three solutions to flood the canals of 24 extracted human maxillary central incisors. A modified PR-30 Cavitron insert was used in a Cavitron 1010 unit for the ultrasonic filing. The clinical crown was removed with a diamond saw and water spray at the cemento-enamel junction. The two major groups were ultrasonic filing versus hand filing; the three subgroups were solution/solvents - 10% EDTA, 2.0% NaOCl, and distilled water.
After filing, the roots were grooved longitudinally with a high speed bur and cracked opened with a mallet and chisel. The …
Apical Closure Induction Using Bone Growth Factors And Mineral Trioxide Aggregate, Kenneth W. Tittle
Apical Closure Induction Using Bone Growth Factors And Mineral Trioxide Aggregate, Kenneth W. Tittle
Loma Linda University Electronic Theses, Dissertations & Projects
This study compared the ability of three different bone growth factor combinations with that of Ca(OH)2 to stimulate apical closure as well as the effectiveness of Mineral Trioxide Aggregate (MTA) as an apical barrier. Fifty-six roots of second and fourth mandibular premolars of seven six- month old beagle dogs were used. Periradicular lesions were created over a four week period. The canals were cleaned and shaped and filled with Ca(OH)2 for one week. They were then irrigated and received one of seven different treatments in a balanced design. Growth factors were placed in a carboxymethylcellulose carrier and delivered …
