Vital Apical Cortical Marginal Ostectomy, Elbert W. Clark

Loma Linda University Electronic Theses, Dissertations & Projects

The dentition has been suspect as an unfavorable influence in the healing potential of the jaws. Today, many surgical procedures are based on the supposition that teeth should be avoided, endodontically treated, or removed from the sphere of tissue infliction. On the other hand, and abundant blood supply and osteogenic capability have been recognized as favorable factors in repair.

An extra oral removal of an osteoid osteoma from the body of the mandible of a thirty-year-old female resulted in vital apicoectomies of her molar teeth as well as the removal of the medullary blood supply. An uneventful course of healing …

The Relationship Between The Lingual Surface Of The Maxillary Central Incisor And The Eminence Of The Mandibular Fossae, Robert A. Huffer

Loma Linda University Electronic Theses, Dissertations & Projects

Gnathologists have suggested that in order to prevent excessive wear on posterior teeth, alveolar bone loss due to traumatic occlusion, and temporomandibular Joint (TMJ) disturbances, the mandibular incisors should disclude the posterior teeth by moving along the lingual surfaces of the maxillary incisors as the condyles move down the articular eminence in protrusion. It is suggested that in order for this to occur, the lingual surface of the maxillary incisors should be steeper than the eminence.

A cephalometric technique was developed to accurately determine the anatomical form of the articular eminence. A regular orthodontic tracing of the head was done …

The purpose of this study was to evaluate three indigenous West African foods--peanuts, black-eyed peas, and egusi seed—as protein supplements when added to the basic West African diet of plant origin. The protein supplements were chosen because they met the criteria of economy, …

The Role Of The Articular Eminence In Mandibular Protrusion, Norman E. Corbett

Loma Linda University Electronic Theses, Dissertations & Projects

Since movements of the TMJ may be translatory, rotary, or both, the form of the articular eminence becomes an integral part of the anatomy of the joint and is important in an understanding of TMJ function. A cephalometric technique was developed to accurately determine the anatomical form of the articular eminence. From a series of cephalograms, taken in various mandibular positions, the protrusive condylar path was determined. This path was also determined from a gnathological recording technique. The paths obtained were observed to be the same. The condylar path and articular eminence curves were mathematically expressed by computer programmed quadratic …

The Effectiveness Of Camphorated Paramonochlorophenol, Metacresyl Acetate, And Prednisolone In Combination As An Antimicrobial Agent, Maurice Cutler

Loma Linda University Electronic Theses, Dissertations & Projects

Post-treatment discomfort following endodontic procedures can be caused by inflammation due to injudicious use of intracanal medicaments. Camphorated paramonochlorophenol, metacresyl acetate, and prednisolone in combination is advocated to reduce the inflammatory potential of the germicide and thus reduce the occurrence of post-operative pain. It is imperative that a medicament retain antimicrobial activity while reducing inflammatory potential.

This investigation was undertaken toward determining on an in vitro quantitative bactericidal versus bacteriostatic basis by use of the broth dilution test tube method whether camphorated paramonochlorophenol, metacresyl acetate, and prednisolone in combination retains antimicrobial activity comparable to selected other commonly used nonspecific germicides. …
