A Comparison Of Cadiax Axiography & Newtom 3g Tomography Condylar Measurements, David Phillip Brock

Loma Linda University Electronic Theses, Dissertations & Projects

This study compared the curves for the mandibular movement obtained from computerized axiography (Cadiax) and NewTom 3G cone beam volumetric tomography.

Fifteen subjects (n=15) from the Loma Linda University School of Dentistry obtained a Cadiax mandibular jaw tracing and a NewTom 3G scan of their condyles and surrounding structures while in centric relation (CR). In addition, three condylar measurements obtained from the Cadiax and the NewTom 3G were compared: sagittal eminential angle (SEA), progressive mandibular lateral translation (PMLT), and early mandibular lateral translation (EMLT).

No differences were noted between the Cadiax and the NewTom 3G mandibular tracings when the gender …

Comparing The Use Of A Manual And A Power Toothbrush By 3-To-4 Year-Old Children, Lorena Delgado Salcedo

Loma Linda University Electronic Theses, Dissertations & Projects

PURPOSE: To compare the ability of three-to four-year-old children in performing toothbrushing with manual versus battery-powered toothbrushes with and without oral hygiene instructions.

METHODS: This study was a randomized, controlled, examiner-blind, 4-period crossover design performed on 50 healthy children, ages 3 to 4 years old. Children were assigned either a manual or power toothbrush at visit one and alternated between the two types of toothbrushes each week, for four weeks. Plaque was scored before and after brushing using the Greene and Vermillion -Simplified Oral Hygiene Index. ^18,19 At their last two visits of the study, the children received brushing instructions …

Influence Of Keratinized Mucosa, Bone Dimensions On Mucosal Recession And Bone Loss, Jeanette Keng Ling Chua

Loma Linda University Electronic Theses, Dissertations & Projects

Background: To accomplish successful esthetic outcome, it would be an advantage if some pre-implant placement conditions could be identified which would predict soft and hard tissue outcomes post-implant placement. This study was designed to evaluate the influence of 1) height of mid-buccal keratinized mucosa at implant surgery and 2) thickness of mid-buccal bone after osteotomy on the amounts of mid-buccal mucosal recession and bone loss during the first year after implant treatment. This report presents the initial 3-month follow-up.

Materials and methods: Nine patients scheduled for surgical placement of a total of 11 single-staged implants, without adjacent teeth and planned …

Training Program To Improve Estimation Of Patients' Periodontal Pain Experience, Yoon Jeong Kim

Loma Linda University Electronic Theses, Dissertations & Projects

Background: The purpose of this study was to determine if periodontal residents could enhance their ability to appraise the pain levels experienced by their patients from probing, using Visual Analog Scale (VAS) to record pain. We hypothesized that with increasing experience by repeated comparisons of the patients' VAS pain ratings with independent ratings by the residents, they would improve their ability to appraise their patients' pain experiences.

Methods: For each of three periodontal residents, 40 consecutive periodontitis patients were asked to express the degree of pain they experienced during the probing. Independently, the residents rated the pain level they perceived …

Influence Of Human Papillomavirus 16 E6 On Trail-Mediated Apoptosis, Theodore O. Garnett

Loma Linda University Electronic Theses, Dissertations & Projects

Viruses have developed sophisticated strategies to evade host defenses and facilitate the production and spread of progeny. HPV 16, whose immune evasion activities can contribute to cervical cancer, is a prime example of such a virus. In this study, we examined the influence of HPV 16 E6 on TRAIL-induced FADD-dependent and -independent pathways in two cellular models: HCT116 colon carcinoma cells and U2OS osteosarcoma cells. We show that transfection of the HPV 16 E6 oncogene into HCT116 cells provides protection from TRAIL-mediated apoptosis. Additionally, we demonstrate that the protection provided by E6 is dose-dependent because higher levels of E6 provide …

Mineralized Bone Allograft In Maxillary Sinuses Histology And Histomorphometry, Sammy Stefan Noumbissi

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Demineralized freeze-dried bone allografts (DFDBA) and deproteinized bovine bone xenografts (DMBBX) have been used for sinus augmentation for many years with varying results, but very little has been reported on the clinical efficacy or the histological analysis of mineralized solvent dehydrated bone allografts (MSDBA) as sinus graft materials. This study histologically and histomorphometrically evaluated an MSDBA material called PUROS to augment atrophic human maxillary sinuses.

Materials & Methods: Seven partially and completely edentulous patients requiring unilateral (n=4) or bilateral (n=3) sinus grafts prior to implant placement were selected for this study. Test grafts consisted of MSDBA, and control …

Pnes: Neuropsychological Impairments & Psychological Symptomatology, Adriana Macias

Loma Linda University Electronic Theses, Dissertations & Projects

The present study utilized a standardized neuropsychological evaluation and self report measures to compare 52 female patients, 18 years of age and older with a video-electroencephalogram (V-EEG) confirmed diagnosis of psychogenic non-epileptic seizures (PNES) (n₁=29) to a group of left temporal lobe epilepsy (L-TLE) demographically matched patients (n₂=23). In an attempt to overcome methodological confounds of previously reported studies, participants were chosen based on stringent exclusion criteria, which barred mixed etiologies. The purpose of this study was to investigate possible differences in neuropsychological functioning, mood, and personality characteristics between individuals with PNES and those with L-TLE. …

Visual-Spatial & Visual-Motor Function In Pediatric Heart Transplant Recipients, Stephanine Dianne Griffone

Loma Linda University Electronic Theses, Dissertations & Projects

Heart surgery is commonly used to repair congenital heart defects and to perform heart transplantation. The associated hypoxia before or during the surgery may cause damage in the parasaggital area of the cerebral cortex, with resulting difficulty during tasks requiring visual-spatial and visual-motor skills. This study compares the performance of children who received a heart transplant during infancy to that of nonclinical children with no medical complications on three visual-motor measures, three visual-spatial measures, and two computerized visual-spatial tasks - a Block Design Matching task and a Mental Rotation task. The children who received a heart transplant achieved significantly lower …
