Ph-Sensitive Liposomes Mediate Cytoplasmic Delivery Of Encapsulated Macromolecules, Robert M. Straubinger, Nejat Düzgüneş, Demetrios Papahadjopoulos

All Dugoni School of Dentistry Faculty Articles

Negatively charged liposomes are endocytosed by the coated vesicle system and accumulate in acidic intracellular vesicles. Liposomes that become unstable at acidic pH improve cytoplasmic delivery of membraneimpermeant macromolecules such as calcein (CAL) and FITC dextran (18 or 40 kDa). Oleic acid (OA): phosphatidylethanolamine (PE) (3:7 mole ratio) liposomes become permeable to CAL at pH < 7.0. Control liposomes of phosphatidylserine : PE or OA : phosphatidylcholine are stable at pH 4-8. OA:PE liposomes promote cytoplasmic delivery of encapsulated CAL to CV-1 cells, as evidenced by the emergence of diffuse, cytoplasmic CAL fluorescence. Delivery requires metabolic energy and is partially inhibited by chloroquine or monensin, which raise the pH of intracellular vesicles. © 1985.

Predictions Of The Effects Of Nonsurgical Periodontial Therapy : Prospective And Retrospective Identification Of Deteriorating Sites, Rik Achille Vanooteghem

Loma Linda University Electronic Theses, Dissertations & Projects

Clinicians rely mostly on clinical signs of disease and radiographic information to evaluate the periodontal condition of patients before and after initial, nonsurgical periodontal therapy. The results of their evaluations lead to decisions that determine the need for further periodontal therapy, often surgical, and may also provide guidelines for subsequent dental restorative treatment.

Thirteen subjects with moderate to advanced periodontal disease received oral hygiene instruction and one single episode of root planing. Three experienced clinicians made made[sic] independent predictions in individual tooth sites of the outcome of this initial therapy. They identified sites that in their opinion probably would not …

Findings were analyzed utilizing contingency tables and Chi-Square analysis. No attempt was made to establish a cause …

Temporomandibular Joint Problem : Report Of Cases., Picharn Chamnannidiadha

Chulalongkorn University Dental Journal

Pain from mastication can be experienced as a discomfort about the face and mouth induced by function and parafunction of the jaws. Masticatory pain has its source in the temporomandibular joints (TMJs) and/or masticatory muscles, and is therefore, directly related to masticatory functions.The main symptom of the myofascial pain dysfunction (MPD) syndrome is a unilateral dull ache of myofascial origin arising from the so- called myofascial trigger zone, located within a muscle or its tendinous at- tachments.This paper intends to report the management of two cases of idi- opathic facial pains such as TMJ or MPD syndromes, with an added …

Force Relaxation In Matched Light Titanium And Stainless Steel Wires, Granville Gene Wilson

Loma Linda University Electronic Theses, Dissertations & Projects

Force relaxation was constantly monitored in light titanium alloy and stainless steel wires over a 7 day period in a simulated use test. The smallest dimension of round titanium wires now available were matched with round stainless steel wires in dimensions that most closely approximated the same stiffness. The .016" NITINOL (Unitek) and TITANAL (Lancer Pacific) wires were compared to .012" Standard Permachrome (Unitek) wire. The .016" TMA (Ormco) wire was compared to .014" Standard Permachrome (Unitek) wire. Six samples were tested for each wire type.

Each wire was ligated with Alastic modules (Unitek) into .018" x .025" slots of …

Effects Of Dentin Chips, Hydroxyapatite, And Demineralized Dentin As Apical Plugs, D. Wylie Brandell

Loma Linda University Electronic Theses, Dissertations & Projects

Two mm plugs of demineralized dentin, hydroxyapatite, or dentin chips were condensed into the apical perforations of 48 anterior teeth of eight adult cynamolgus monkeys. The remainder of the canals were obturated with gutta percha and Grossmans sealer using lateral condensation technique. The degree of hard tissue formation and inflammation was evaluated at three and six months. No significant changes were noted between various materials at three months. However, after six months, the samples with apical plugs of hydroxyapatite had more hard tissue formation and less inflammation than others.

A Comparison Of Enamel Detachments After Debonding Between Unitek's "Dynalok" Bracket And A Foil-Mesh Bracket: A Scanning Electron Microscope Study, Robert E. Meister

Loma Linda University Electronic Theses, Dissertations & Projects

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 …

Orthodontists' Attitudes Toward Expanding Career Opportunities For The Dental Hygienist In Orthodontics, Julie A. Foster

Dental Hygiene Theses & Dissertations

The purpose of this survey was to determine attitudes of orthodontists toward employing dental hygienists. A self-designed, 33 item questionnaire was used to obtain descriptive data. The questionnaire was mailed to a random sample of orthodontists chosen from the United States portion of the Orthodontic Directory of the World (N=500). Data were obtained from 298 orthodontists for a 58.6 percent response rate.

The study suggests that although orthodontists believe dental hygienists are important oral health professionals (96.2 percent) and important parts of the orthodontic practice (32.6 percent), only 10.9 percent of orthodontists surveyed employ dental hygienists. Factors determined to be …

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 …

Cephalometric Changes In The Soft Tissue Chin After Orthodontic Treatment, Ruchi Nanda Singh

Loma Linda University Electronic Theses, Dissertations & Projects

This study was performed to cephalometrically assess the soft tissue chin changes from orthodontic treatment and after 5 years post-treatment. Variability in the soft tissue chin structure between the different facial types and between the sexes was also evaluated.

Sixty patients, treated by Dr. Ricketts, were selected from the Rocky Mountain Data system files. Pretreatment, post-treatment and 5 year post-treatment cephalograms were taken on each patient and the soft tissue chin thickness was measured at six points around the symphysis. Means and standard deviations were calculated for each point on the symphysis by sex and facial type.

The post-treatment data …
