The Effect Of Naocl, Ca(Oh)2, Mta And Mtad On Root Dentin Fracture Resistance, Sunil Ilapogu

Loma Linda University Electronic Theses, Dissertations & Projects

Various materials are used for the treatment of immature teeth that have been subjected to trauma or decay. It is not well established what effect these materials may have on the immature root dentin. A concern would be the resistance to fracture of the remaining root dentin. The purpose of this study was to compare the resistance of fracture of bovine teeth treated with sodium hypochlorite, calcium hydroxide, gray MTA and gray MTA in conjunction with MTAD after certain periods of time. One hundred and ninety five freshly extracted, intact bovine incisors were prepared using a modified Haapasalo and Orstavik …

Cbct Panoramic Images Vs. Traditional Panoramic Radiographs, Sunny Young Hutchinson

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this research was to compare the accuracy of angular measurements of the panoramic image of the Newtom 9000™ Cone Beam Computed Tomography (CBCT) with the Sirona™ Orthophos panoramic unit. The study was separated into three parts: phantom study, patient study, and archform study. The phantom study used fabricated phantom typodonts to compare angular measurements between the Newtom 9000™ panoramic image and the Sirona™ panoramic radiograph. Accuracies of the measurements were then determined by comparing the values to the actual phantom typodont. No marked differences in angular measurements were recorded for the phantom typodont using either of the …

The Effect Of Rapid Maxillary Expansion On Nasal Cavity Volume And Nasal Airway Resistance, Todd Ehrler

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of Rapid Maxillary Expansion (RME). Using Cone Beam CT scanning technology and Rhinomanometry, the volume and nasal airway resistance (NAR) of the nasal cavity was measured immediately before and after RME.

27 subjects (16 female, and 11 male), ages 9-18 were enrolled in the study. After RME all subjects had a statistically significant increase in nasal cavity volume. The pre expansion group experienced a statistically significant reduction in NAR when compared to the post expansion group. Individuals with a high pre expansion NAR experienced the greatest reduction in NAR. The correlation between change in volume …

Levels Of Intravenous Enterococcus Faecalis That Cause Heart Colonization, Louis Zane Stromberg

Loma Linda University Electronic Theses, Dissertations & Projects

While previous studies have shown that presence of bacteria in systemic circulation can cause infective endocarditis, there is no information on the specific amount of bacteria necessary to cause this condition. The purpose of this study was to establish the minimum level of circulating bacteria that will cause colonization of damaged heart valves in rats. Fifty-two Sprague-Dawley rats were anesthetized and their heart valves were damaged using an established protocol. A clinical isolate of Enterococcus faecalis was transformed with a plasmid bearing the luxF and Chloramphenicol cassettes to label the bacteria with the light-emitting protein. After four weeks, the rats …

The purpose was also to establish norms for joint space for patients with and without degenerative joint disease. Correlations to distal condyle position and angle classification were described. 123 consecutive patients, 77 female and 46 male T1 NewTom records were reviewed. Severity of DJD was classified according to none, mild, moderate, and severe. Sagittal …

Cone Beam Ct And Digital Radiography. A Comparative Study Of P/A Cephalometrics., Michael John Erickson

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine if Rickett's posterio-anterior (P/A) cephalogram measurements could be obtained from Cone Beam Computerized Tomographic (CBCT) images taken on the NewTom QR-DVT 9000™.

Fifteen frontal cephalometric radiographs were chosen for good image quality, with no regard for patient age or gender. Each cephalogram was traced three times by the same operator using ZeroBase™ software. Landmarks were located and measured according to the Rickett's frontal analysis technique. Methods were devised for obtaining analogous measurements using CBCT images on the same group of patients.

Measurements obtained using CBCT correlated well with those obtained using the …

Condylar Remodeling After Distraction Osteogenesis And Bilateral Sagittal Split Osteotomy, Robert Barker Hoffman

Loma Linda University Electronic Theses, Dissertations & Projects

The present pilot study is a histological evaluation of mandibular condyles taken from minipigs that underwent either traditional mandibular advancement (bilateral sagittal split osteotomy), or a distraction osteogenesis procedure to advance the mandible. One pig received a bilateral sagittal split osteotomy with an immediate mandibular advancement of 14 mm, while another pig underwent distraction osteogenesis consisting of a gradual advancement of 2 mm per day to advance the mandible the same distance. The control animal received no surgery.

In the present study, the mandibular condyles of the three pigs (2 control, 2 bilateral sagittal split osteotomy, and 2 distraction osteogenesis) …

Bone Formation Using Platelet-Rich Plasma + Allograft: An Experimental Study In Sheep, Edgar Grageda

Loma Linda University Electronic Theses, Dissertations & Projects

Recently Platelet-Rich Plasma has been proven to be an effective regeneration adjunct when combined with autogenous bone in the reconstruction of mandibular defects. However, little is known about the effect of PRP when combined with a bone allograft in the maxillary sinus.

The purpose of this study was to quantitatively evaluate the ability of PRP to enhance bone regeneration in the maxillary sinus of sheep when combined with DFDBA + CCFDBA. Ten sheep were selected for bilateral sinus augmentation DFDBA + CCFDBA + PRP (test) and DFDBA + CCFDBA (control). Five were sacrificed at 3 months and the other five …

Effect Of Anti-Tgfß1 And Pycnogenol® On Scar Formation In Rats, Pilseong Kim

Loma Linda University Electronic Theses, Dissertations & Projects

Wound healing is a complex biologic process that involves chemotaxis and division of cells, neovascularization, synthesis of extracellular matrix proteins, and remodeling of the repaired tissues. Of equal importance is the restoration of normal tissue structure and function without scar formation. The aim of this study was to find out the clinical effects of anti-TGFß1 and Pycnogenol® on scarless wound healing on rat skin.

An acute incision wound model was used with 20 healthy rats. Four incisions were made on each rat's skin and 4 different variables were applied by local infiltration. The four variables were anti-TGFß1, Pycnogenol®, PBS, and …

Pain Experienced By Patients Using Thinner Vs. Thicker Probes During Probing, Mohamed A. Hassan

Loma Linda University Electronic Theses, Dissertations & Projects

The aim of the present study, performed during periodontal recall visits, was to compare the levels of pain experienced by patients during periodontal probing using probes with tip diameters of either 0.40 mm or 0.63 mm.

Prior to the maintenance procedures, three groups of 20 adult patients were examined by 3 different therapists. Diagonal maxillary/mandibular quadrants were probed with a 0.40 mm and a 0.63 mm probe, respectively. At the completion of probing of each quadrant, the patients were asked to describe their pain using a Visual Analog Scale (VAS).

The results were as follows: Most patients showed low VAS …

Detection Of Bacteria To Dental Tissue By Low-Light Imaging, G-Hong Robert Hsu

Loma Linda University Electronic Theses, Dissertations & Projects

Bacteria have been shown to play an important role in the development of pulp and periradicular disease. The source of the infective bacteria is most often the oral cavity. Previous studies have detected bacteria in teeth that are structurally intact that seemingly have no communication intraorally. Anachoresis has been proposed as a mechanism for localizing circulating bacteria to such teeth. In several previous bacteriologic anachoresis studies, bacteria have been found to localize in inflamed dental tissues. The criticism most commonly associated with these investigations has been the potential contribution of contaminant bacteria resulting in false positive findings.
