Establishing Norms For A Mexican Group Using Ricketts, Steiner And Arnett Analyses, Mauricio Gonzalez Balut

Loma Linda University Electronic Theses, Dissertations & Projects

Most existing cephalometric analyses are based on norms for the Caucasian population. Therefore, they cannot be properly applied for Mexican or Hispanic patients. Ethnic variations in the normal positions of the maxilla and mandible influence and alter the diagnosis and treatment plan for each of the different type of malocclusions. Previous studies have addressed the difference between the Caucasian norms and the Hispanic norms, this indicates the variety of their skeletal, dental and facial features.

It is the purpose of this study to establish specific cephalometric standards for the native Mexican group, using the Steiner and Ricketts analyses along with …

Anion Induced Blue To Purple Transition In Bacteriorhodopsin, Mrunalini Pattarkine, Anil K. Singh

Faculty Works

Purple membrane (PM, λ" role="presentation">λmax" role="presentation">max 570 nm) of H. halobium on treatment with sulphuric acid changes its colour to blue (λ" role="presentation">λmax" role="presentation">max 608 nm). The purple chromophore can be regenerated from the blue chromophore by exogeneous addition of anions such as CI−" role="presentation">− and HPO42−" role="presentation">2−4. Chloride ion is found to be more effective than the dibasic phosphate ion in regenerating the purple chromophore. Nevertheless, one thing common to the anion regeneration is that both CI−" role="presentation">− and HPO42−" role="presentation">2−4 show marked pH effect. At pH 1.0 the efficiency of …

The Mmpi-2 Clinical Scales And Clinical Diagnosis: Differentiating Between Schizophrenic And Bipolar-Manic Disorders, Laura M. Volkmann

Graduate Theses

The validity of the Minnesota Multiphasic Personality Inventory (MMPI-2) clinical scales in differentiating schizophrenia and bipolar-manic disorders was evaluated in terms of MMPI-2 congruence with psychiatric hospital treatment team diagnoses. From a pool of 286 MMPI-2 profiles, valid profiles were obtained on 5 schizophrenia (paranoid type) inpatients and 5 bipolar-manic disordered psychiatric inpatients and were assessed by using each of four MMPI profile classification methods. Overall, the rate of agreement between treatment team diagnosis and the MMPI profile classification methods for both the schizophrenia (paranoid type) and bipolar-manic disordered groups was inconclusive. The results suggest that the MMPI-2 is of …

Group Comparability: A Multiattribute Utility Measurement Approach To The Use Of Random Assignment With Small Numbers Of Aggregated Units, C. Anderson Johnson, John W. Graham, Brian R. Flay, William B. Hansen, Linda M. Collins

CGU Faculty Publications and Research

It is not always possible, especially in large-scale evaluation research, to ensure that random assignment will produce groups that are comparable on any number of potentially important factors. Typically, gaining comparability has been achieved only at the expense of random assignment. A method is presented that allows multivariate comparability while making only minimal restrictions on randomization. The procedure is demonstrated in the context of assigning 63 aggregated units (schools) to 28 experimental and control conditions. Good comparability of groups for all primary main effects and interactions was verified for 15 individual variables.

The Bender Gestalt And Symbol Digit Modalities Tests As Cerebral Dysfunction Screening Instruments :A Comparative Evaluation, Bruce R. Wright

Dissertations

Problem

One of the problems confronting the psychologist in an institutional setting is the selection of appropriate instruments for the screening and diagnosis of a variety of psychological problems. Among the more subtle and yet far-reaching problems of this sort are those associated with disease, trauma, or congenital defect of the central nervous system. It was the purpose of this study to evaluate the usefulness of two well-known psychological tests as screening instruments for neurological dysfunction in a large and varied institutional population.

Method

The Bender Visual-Motor Gestalt Test (BGT) and Symbol Digit Modalities Test (SDMT) were administered to one …

The Cardiovascular Effects Of Human Contact With Coronary Artery Disease Patients In The Coronary Care Unit, Margaret A. Palmour

Loma Linda University Electronic Theses, Dissertations & Projects

Ten coronary artery disease patients were selected using purposive method of sampling and observed for six hours. It was postulated that 1) Human contact with coronary artery disease patients in the coronary intensive care unit would be associated with significant (p = 0.05) changes in the electrocardiogram such as: (a) increased heart rate more than 10 per cent, (b) changed atrio-ventricular conduction more than 10 per cent, (c) changed ST segment one millimeter or more and (d) increased frequency of ectopic beats more than 10 per cent. 2) The degree of stress and cardiac response was related to a number …

Cephalometric Norms For The Mexican Population Using The Ricketts, Steinar, And Tweed Analyses, Eduardo A. Velarde

Loma Linda University Electronic Theses, Dissertations & Projects

In order to investigate the characteristics of the facial complex of the Mexican and to compare them with the Caucasian, a sample of 40 subjects, 31 males and nine females, of Latin American origin from Chihuahua, Chihuahua, Mexico, with a mean age of 16.6 years, were selected for this study. The criteria for selection were visual and only individuals with clinical normal, Angle Class I occlusion were chosen.

Lateral head Roentgenograms were obtained and cephalometric evaluation of the Skeletal and Dental Pattern was carried out using the Ricketts, Steiner, and Tweed Analyses.

The mean values for the Mexican were compared …

An Odontometric Study Of Five Contemporary Western United States Indian And Alaskan Eskimo Groups, John A. Matis

Loma Linda University Electronic Theses, Dissertations & Projects

The morphologic characteristics of the oral cavity in five contemporary Western Indian and Alaskan Eskimo groups have been investigated by the use of study models of the dental archs. The sample consisted of 216 individuals, including 44 Navajos, 43 Apaches, 40 Papagos, 42 Pimas and 47 Alaskan Eskimos.

The first purpose of the study was to determine the extent of investigator error. This was accomplished by remeasuring many morphologic traits of the dentition in 125 Indians which had previously been measured by different investigators using the same study models. It was found that investigator error can be significant, even in …

A Cephalometric Comparison Of The Chamula, Mayo And Navajo Indians, Norman C. Bunker

Loma Linda University Electronic Theses, Dissertations & Projects

Lateral head x-rays were obtained on selected samples of 24 Chamula, 29 Mayo and 39 Navajo Indians for cephalometric comparison.

Cephalometric evaluation was carried out by means of the Bjork analysis. Mean values for each of the Indian groups were determined and compared with each other and with the mean values of a group of Swedish conscripts studied by Bjork. The mean values were statistically analyzed and and subjected to the Student's "t" test to determine the significant levels of differences.

Results revealed that in comparing the three Indian groups significant differences do appear. They are few and general concordance …

Occlusal Patterns And Tooth Morphology In The Navajo Indians Of Monument Valley, Utah, Leroy C. Trnavsky

Loma Linda University Electronic Theses, Dissertations & Projects

The occlusal patterns and morphology of the dentition of the Navajo Indians were studied and compared to those of populations of known Mongoloid ancestry. Thirteen dento-anthropomorphic characteristics were studied from plaster casts obtained from fifty-four Navajo Indians from the Monument Valley area of Utah. The thirteen characteristics included were:

1. Degree of shovel-shape of the maxillary centrals and laterals.
2. Presence of a winged appearance in the maxillary centrals.
3. Mesiodistal crown diameters of the maxillary centrals and laterals.
4. Type of lingual tubercle on the maxillary centrals and laterals.
5. Cusp pattern of mandibular molars.
6. Cusp pattern of maxillary molars.
7. Frequency of cusp of …
