The Effect Of Endodontic Therapy On The Incidence Of Radiation Caries In Dogs, James A. Abbott
The Effect Of Endodontic Therapy On The Incidence Of Radiation Caries In Dogs, James A. Abbott
Loma Linda University Electronic Theses, Dissertations & Projects
Endodontic therapy was evaluated as a possible control or prevention modality of radiation type dental caries in dogs. Two adult male dogs with permanent dentitions had endodontic therapy performed on alternating teeth in each jaw. The nontreated teeth served as controls.
The dogs were irradiated with 7000 rad Cobalt-60 radiation fractionated over an eight week period. The dogs were killed at 60 and 182 days post-irradiation. The teeth were removed from the jaws and immersed in methylene blue dye, sectioned, and the dye penetration pattern photographed. Diffusion of the dye into the tooth structure was quantified and statistically analyzed.

Xeroradiography & Conventional Radiography : Comparative Imaging Of The Temporomandibular Joint, Nelson R. Gatov
Xeroradiography & Conventional Radiography : Comparative Imaging Of The Temporomandibular Joint, Nelson R. Gatov
Loma Linda University Electronic Theses, Dissertations & Projects
An investigation was conducted to evaluate the application of Xeroradiography for imaging the Temporomandibular Joint using the Updegrave and Weinberg positioning boards and to compare these images to those obtained by conventional radiography using the same positioning boards.
A cadaver head in which three spherical radiopaque implants had been placed was used in this study. A General Electric Model 1000 (Dental Unit) was the source of radiation. The conventional radiographs were produced on Dupont Cronex 2DC film and processed by a Phillips 810 automatic processed by a Xerox "125 System".

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 …
