Root Exposure And Its Effect On The Fluid Movement Within The Tooth, William J. Busch Aug 1971

Root Exposure And Its Effect On The Fluid Movement Within The Tooth, William J. Busch

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the fluid movement in dentin associated with the exposure of the root surface for varying periods of time ranging from 75 minutes to 30 days. Eight kittens received experimental defects on the roots of the canines. Just prior to sacrifice a fluorescing dye was injected intraperitoneally to make the fluid within the dentin visible under ultraviolet light. Frozen ground sections were prepared and examined. The results showed that the exposed side of the root had a reduced amount of fluid fluorescence when compared to the opposite side of the tooth which had an intact root surface. The …


The Effect Of Elevated Glucose On Neutrophilic Phagocytosis In Genetically Diabetic Mice, Larry B. Thompson May 1971

The Effect Of Elevated Glucose On Neutrophilic Phagocytosis In Genetically Diabetic Mice, Larry B. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Infiltration to an injury site or area of bacterial contamination by polymorphonuclear leucocytes (or neutrophils) is an early and essential phase of the early inflammatory reaction. Their action on foreign matter is the most critical step taken by body defense mechanisms in the first 24 hours. Anything which interferes with that action, phagocytosis, greatly hampers early inflammation. This study was designed to see the effect of elevated glucose levels on neutrophil phagocytosis in a unique strain of genetically diabetic mice.

Twenty-two diabetic and twenty-four control female mice were used. Blood glucose determinations and total white counts were made on each …


Histopathological Variations Of Periapical Granulomas And Radicular Cysts, Thanapen Kanchanasut May 1971

Histopathological Variations Of Periapical Granulomas And Radicular Cysts, Thanapen Kanchanasut

Loma Linda University Electronic Theses, Dissertations & Projects

The periapical dental granuloma and cyst is the most frequent sequela of pulpitis. These lesions are always intraosseous and often become quiescent after the acute phases are over, forming a space which primarily consists of chronic inflammatory tissue. This chronic inflammatory tissue usually appears as a one-centimeter area of punched out bone on the x-ray film and is referred to as a dental granuloma. Should epithelium choose to proliferate in this inflammatory area, it may undergo subsequent cystic degeneration forming the typical periapical cyst. While much has been written with regard to the etiology and treatment of the apical cyst …


The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann May 1971

The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the histopathological and clinical changes that occurred when a continuous supply of exogenous acid or base, at varying pH, was delivered adjacent to the gingival crest of the monkey. A related goal was to develop a monkey model system which would deliver test solutions continuously and atraumatically, to the experimental gingival sites.

Two young adult female monkeys had a perfusion apparatus attached to certain maxillary teeth so that test solutions were deposited atraumatically to the marginal gingival tissues. During the experimental periods the animals were kept in primate restraining chairs and fed …


A Clinical And Microscopic Evaluation Of Plaque Removal And By The Hydrodent Brush, Soertini E. Lambri May 1971

A Clinical And Microscopic Evaluation Of Plaque Removal And By The Hydrodent Brush, Soertini E. Lambri

Loma Linda University Electronic Theses, Dissertations & Projects

The Hydrodent toothbrush was compared to conventional toothbrush (Lactona # 19) in its effectiveness on removing the plaque, eliminating the pocket depth, and improving the gingival tissue condition.

Forty six male and female subjects with the age range of 18 to 50 years old participated in a 5 month study with 4 week intervals. Each subject received a Hydrodent brush of soft, medium, and hard textures and a conventional toothbrush. The toothbrushes were given randomly and the subject served as his own control.

Clinical and histological evaluations were made after the use of each toothbrush. The clinical evaluation showed some …
