The Effect Of Warmed Humidified Oxygen On The Temperature Of Depressed Newborns, Earlene Scharping

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the effect of warmed humidified oxygen on the body temperature of depressed newborns and compare it to the effect of unwarned un-humidified oxygen administered under similar circumstances. The sample group consisted of a total of ten infants (five control and five experimental) with birth weights > 2000 gms who had an Apgar score of less than seven at birth and who required the administration of oxygen. The control group received oxygen in the routine delivery room manner (unwarned and un-humidified). The experimental group received oxygen which had been warmed to a temperature of …

Ultrasonic Versus Hand Filing Of The Human Root Canal System, Howard W. Scholz Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

A comparison was made of ultrasonic filing versus hand filing using three solutions to flood the canals of 24 extracted human maxillary central incisors. A modified PR-30 Cavitron insert was used in a Cavitron 1010 unit for the ultrasonic filing. The clinical crown was removed with a diamond saw and water spray at the cemento-enamel junction. The two major groups were ultrasonic filing versus hand filing; the three subgroups were solution/solvents - 10% EDTA, 2.0% NaOCl, and distilled water.

After filing, the roots were grooved longitudinally with a high speed bur and cracked opened with a mallet and chisel. The …

Community Health Nursing Assessment And Counseling Of The Breast-Feeding Primipara, Donita Rotherham

Loma Linda University Electronic Theses, Dissertations & Projects

An experimental study was conducted with twenty-one breast-feeding primiparas during the initial four-week post-partal period to test the effect of in-home community health nursing assessment and counseling on the breast-feeding success rate. It was hypothesized that mothers receiving assessment and counseling regarding physical, informational and psychosocial needs, would be more successful than those who were not counseled.

Criteria for success were: (1) breast-feeding at four weeks postpartum, (2) an adequate milk supply as evidenced by no need for formula supplementation to keep the baby satisfied, (3) an infant weight gain of one to two pounds during the four-week period, and …

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.

Relationship Between Some Demographic Characteristics And Adverse Reactions Experienced By Women Undergoing A Therapeutic Abortion While Awake, Karen K. House

Loma Linda University Electronic Theses, Dissertations & Projects

With the liberalization of abortion laws by the Supreme Court in 1973, American women have been able to obtain therapeutic abortions in hospitals and out-patient clinics in ever increasing numbers. With the increased number of women seeking abortions the medical field has responded with abortion procedures that are safe and relatively quick. With the speed doctors use to perform the procedure, many women may wish to take advantage of the medically safer method of abortion under local anesthesia. However, some women are unable to withstand the psychological and physical stress associated with a therapeutic abortion while awake. It would be …

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 …
