The intent of this paper was to: 1. Evaluate the mode of adhesive failure when debonding both flexible and rigid base orthodontic brackets. 2. Evaluate the bracket bases for enamel detachments. 3. Measure the enamel detachments.
After preforming shear test on flexible and rigid base orthodontic brackets mounted to extracted human teeth it was determined that failure occurred at the enamel/adhesive interface 30% of the time, at the bracket/adhesive interface 10% of the time and a combination of these 60% of the time for both groups.
Five brackets from each group were evaluated for enamel detachments using energy dispersive x-ray …

This study utilized the imaging technique of computerized tomography (CT). Scans taken with a GE CT/N 8800 scanner of an adult cadaver and a 12-patient group were obtained through the Loma Linda University School of Dentistry, TMJ Department, and Loma Linda University Medical Center, Department of Neuroradiology.
The lateral scout image and a lateral cephalogram of the cadaver were compared using six angular measurements for facial type from Ricketts' Cephalometric Analysis. The six measurements, Maxillary Depth, Facial Depth, Mandibular Arc, Mandibular Plane, Lower Face Height and Facial Axis, were found to be similar. This allowed the investigator to rely exclusively …
Third Molar Eruption Prediction, Michael L. Jacobsen
Third Molar Eruption Prediction, Michael L. Jacobsen
Loma Linda University Electronic Theses, Dissertations & Projects
The diagnosis and treatment of third molars has often been cited as a special problem to the orthodontist. If the prognosis of third molars could be determined, orthodontic treatment could progress on a more positive basis.
This study was designed to provide a method of deciding whether developing third molars will erupt or become impacted.
Records from 130 orthodontically treated cases of Dr. Fredsall8 were studied. Several factors were evaluated and measured using the patients' cephalometric radiographs.
The actual fate of the third molars were recorded in the hope it could be used to predict what to expect from …
