Histologic Probe Position In Treated And Untreated Human Periodontal Tissues, Clifford Fowler
Histologic Probe Position In Treated And Untreated Human Periodontal Tissues, Clifford Fowler
Loma Linda University Electronic Theses, Dissertations & Projects
This study was designed to histologically determine the relationship of the periodontal probe tip to the periodontal tissues during probing of untreated periodontal pockets and periodontal pockets treated with oral hygiene and root planing. Human, condemned, single rooted teeth with buccal probing pocket depth at least 6 mm were used. Two groups of specimens were included; 12 untreated teeth from 6 patients and 15 treated teeth from 10 patients.
In the treated group, the effects of therapy were monitored clinically every two weeks until maximum improvement had taken place. A periodontal probe tip was then inserted on the buccal aspect …

The Effects Of Orthodontic Repositioning Into A Surgically Expanded Site On Bone Formation And Tooth Mobility In A Baboon, Anthony B. Lier
The Effects Of Orthodontic Repositioning Into A Surgically Expanded Site On Bone Formation And Tooth Mobility In A Baboon, Anthony B. Lier
Loma Linda University Electronic Theses, Dissertations & Projects
For sometime, expansion of the maxillary arch, by means of surgical and mechanical procedures, have been acknowledged with minimal attention directed toward the mandible. In this pilot study a surgical technique was employed in separating the mandible, A-P, at the symphysis. The interosseous void, approximately 10 mm., was then filled with autogenous bone marrow collected from the greater trochanter and the crest of the ilium.
The surgical site was then maintained for a period of eight (8) weeks with the aid of a precast chromium-cobalt splint and titanium mesh placed intradentally and at the symphysis, respectively. Following the stabilization period …

The Effects Of Palatal Expansion Therapy On The Periodontal Supporting Tissues, Kenneth R. Greenbaum, Bjorn U. Zachrisson, John K. Pearson, Roland D. Walters, Jan Egelberg, James R. Wise, Grenith Zimmerman
Loma Linda University Electronic Theses, Dissertations & Projects
Four periodontal parameters were examined to determine the effect of rapid and slow palatal expansion techniques on the supporting structures at the buccal aspect of the maxillary first permanent molars. The parameters examined included the levels of crestal alveolar bone and soft tissue attachment (relative to the cemento-enamel junction), the depth of the gingival sulcus, and the height of the attached gingiva. The area between the buccal roots was inspected for possible furcation involvement. Twenty-eight patients had experienced a rapid technique utilizing a tissue-born, fixed, split-acrylic appliance, while thirty-three patients had been treated with the quad-helix appliance associated with slow …
The Effect Of Mechanical Plaque Control On The Clinical Parameters Of Human Periodontal Disease, John F. Cercek Jr.
The Effect Of Mechanical Plaque Control On The Clinical Parameters Of Human Periodontal Disease, John F. Cercek Jr.
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this investigation was to determine the degree of healing which takes place in the periodontal tissues as a result of supragingival and subsequent subgingival plaque control attempts without any associated supra- or subgingival instrumentation and root planing.
Seven patients with moderate to severe periodontitis were finally selected for the study. Measurements were made on maxillary and mandibular incisors, cuspids and premolars to establish base line plaque scores, bleeding scores, probing pocket depths, and probing attachment levels. The patients were then instructed in the use of toothbrushes, dental floss and interdental brushes where indicated. Measurements were repeated at …

A Comparative Study Of Tensile Properties In Five Orthodontic Wires, Charles B. Mcdermott
A Comparative Study Of Tensile Properties In Five Orthodontic Wires, Charles B. Mcdermott
Loma Linda University Electronic Theses, Dissertations & Projects
The tensile properties of .017 x .025" stainless steel. Multiphase, Blue Elgiloy, beta titanium, and Nitinol were tested and compared. All wires were tested in the "as received" condition. Fifteen samples of each type of wire were tested in order to determine the (1) modulus of elasticity, (2) .2% yield strength, (3) ultimate tensile strength, (4) percentage elongation and (5) maximum elastic deflection.
The modulus of elasticity and .2% yield strength are the most important properties to orthodontists because of their influence on the wire's stiffness, strength and range. The ratio of yield strength/modulus of elasticity, termed maximum elastic deflection, …
The Effects Of Maxillary Quad-Helix Appliance Expansion On Cephalometric Measurements In Growing Orthodontic Patients, Steven Wesley Frank
The Effects Of Maxillary Quad-Helix Appliance Expansion On Cephalometric Measurements In Growing Orthodontic Patients, Steven Wesley Frank
Loma Linda University Electronic Theses, Dissertations & Projects
This study was conducted to examine the effects of maxillary quad-helix expansion on frontal and lateral cephalometric measurements in growing orthodontic patients. Twenty subjects, nine girls and eleven boys (x age = 10 years, 3 months), each exhibiting at least a unilateral posterior lingual cross-bite that had been treated with a maxillary quad-helix appliance, were selected for this study. Posterior-anterior and lateral cephalometric radio graphs were taken at the beginning of treatment (T1), when the appliance was removed (Tprog' x time = nine months) and at retention (T2) and subsequently traced. The T1 …
The Effect Of Folic Acid Supplementation On Gingival Healing After Oral Hygiene Therapy, Marilyn J. Wankier
The Effect Of Folic Acid Supplementation On Gingival Healing After Oral Hygiene Therapy, Marilyn J. Wankier
Loma Linda University Electronic Theses, Dissertations & Projects
To determine the effect of folic acid supplementation on gingival healing after oral hygiene therapy, eight teeth (#3, 4, 5, 6, 11, 12, 13, 14) of sixteen human subjects with moderate levels of gingival irritation were studied. Clinical parameters included measurement of gingival fluid, pocket depth, bleeding upon probing, and plaque. Serum and red blood cell folic acid levels were determined using radioimmunoassay (RIA). Based on clinical parameters and serum folate levels, two similarly matched groups were established. The teeth were scaled and polished. Brushing and flossing instructions were given.
After one week of oral hygiene therapy alone, the experimental …

Cineradiography Of The Temporomandibular Joint : A Research Entity And Diagnostic Modality, L. Albert Lewis
Cineradiography Of The Temporomandibular Joint : A Research Entity And Diagnostic Modality, L. Albert Lewis
Loma Linda University Electronic Theses, Dissertations & Projects
Readily accessible equipment as utilized for cineangiography has been demonstrated to be useful in producing dynamic studies of the temporomandibular joint.
The reproducible studies have been obtained without adaptation of equipment. Methods used in this project were based on principles which have been advocated for the past thirty years for static radiographs of the temporomandibular joints.
Studies were made of a variety of subjects varying in size and joint integrity. Diagnostic views were obtained on all subjects showing normal osseous joint structures and typical joint function via the use of motion picture records. Changes in osseous joint structures were readily …
Comparative In Vitro Studies On Bond Strength And Sealant Polymerization, Gerald E. Sievers
Comparative In Vitro Studies On Bond Strength And Sealant Polymerization, Gerald E. Sievers
Loma Linda University Electronic Theses, Dissertations & Projects
A comparison of two orthodontic sealants and two adhesives was made. An experimental adhesive was tested (Unitek*) also an experimental sealant (Unitek**) was evaluated for its ability to polymerize into a thin film. An established adhesive and sealant system (Concise***) was compared with the above products.
The factors which were considered important to the study were: the strength of the bond formed; the working efficiency; the ability for these materials to bond to the lingual of teeth; and the value of using contralateral teeth when testing bond strength.
An Instron testing machine was used to record the shear strength of …
