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".

Cephalometric Objectives For The Maxillary Central Incisor, John Mickey Damerell

Loma Linda University Electronic Theses, Dissertations & Projects

A cephalometric study was conducted to determine the ideal inclination of the maxillary central incisor for various facial patterns. Selected measurements were made on lateral headplate tracings of three samples: ideal, random and Class III malocclusions. Statistical analysis of data included means, standard deviations, simple correlations and stepwise regressions.

The Frankfort plane was found to be the most reliable reference plane when measuring the inclination of the maxillary central incisor. The maxillary central incisor inclination was found to be dependent upon the lower incisor position and inclination, chin position and the anterior cranial base inclination. A formula was produced to …
