A Method Of Analyzing Mandibular Movement, Richard B. Mccoy
A Method Of Analyzing Mandibular Movement, Richard B. Mccoy
Loma Linda University Electronic Theses, Dissertations & Projects
Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.
The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …

Assisting Mothers To Successfully Breast Feed Their Babies, Annabelle Moore
Loma Linda University Electronic Theses, Dissertations & Projects
This experimental study tested the effect of a teaching program on success of a group of mothers desiring to breast feed their babies. It was hypothesized that mothers receiving specific instructions on the physiology of lactation and the proper sucking technique would have greater success than mothers not so instructed.
To be categorized as successful the mothers had to have an adequate supply of milk and had to express satisfaction with breast feeding. Criteria for adequacy of milk supply consisted of weight gain of the infant within accepted norms without use of supplementary formula.
Twenty breast feeding mothers who delivered …
A Clinical Comparison Of Six Orthodontic Techniques, Erik H. Madsen
A Clinical Comparison Of Six Orthodontic Techniques, Erik H. Madsen
Loma Linda University Electronic Theses, Dissertations & Projects
Controversy exists concerning the relative superiority of various orthodontic techniques because of the difficulties encountered in making comparative clinical studies of these techniques which are scientific and statistically meaningful. The purpose of this study was to clinically compare six different orthodontic techniques which are currently being taught, relative to a number of criteria, and to do it in a scientifically significant manner.
In order to eliminate as many of the irrelevant variables as possible, the patients were required to pass a relatively stringent screening to participate. Among other things, the patients had to have first molars in Class I relation …

Using A Participating Relationship To Improve Teen-Age Unwed Mother's Self-Esteem, Linda Gail Reeves
Loma Linda University Electronic Theses, Dissertations & Projects
The study was to provide an approach to help teen-age unwed mothers increase their feelings of self-esteem and thereby attain a conceptual buffer for better coping with life. Self-esteem was defined as individual perception of the worth of oneself relative to that of significant others. The hypothesis tested was that the participating relationship a community health nurse has with a teen-age unwed mother will significantly increase the mother's self-esteem as measured by statistical Q-Sort analysis.
A convenience sample of twenty teen-age unwed mothers was obtained from referrals from San Bernardino County Health, Welfare, and Probation Departments. The girls were between …
Influence Of Hospital Communication On Health Supervision Of High-Risk Infants, Alda L. Forte
Influence Of Hospital Communication On Health Supervision Of High-Risk Infants, Alda L. Forte
Loma Linda University Electronic Theses, Dissertations & Projects
The study was conducted to explore the extent to which communication about high-risk infants identified prior to hospital discharge, influences the public health nursing supervision to these infants during the neonatal period. A high-risk infant was defined as one that stands a greater than average chance of developing neonatal, life threatening disease or sequellae (physical, intellectual, or social handicap) due usually to maternal health or social factors, infant factors such as length of gestation, birth trauma, or complications at birth. The hypothesis tested was that when high-risk infants are identified prior to hospital discharge and this information communicated on the …

Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor
Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor
Loma Linda University Electronic Theses, Dissertations & Projects
Modification of cephalometric roentgenographic procedures provided a means to identify the anterior borders of the right and left masseter muscles and relate them to surrounding dentoskeletal elements. Attachment of short, stiff, wires to the cheeks in a position superficial to the anterior borders of the muscles, subsequent to palpation and prior to exposure of the roentgenographic film, was the procedure used. The bi-lateral images projected on the film were averaged and traced along with dentoskeletal elements including those associated with skeletal type. This line representing the anterior border of the musculature was used to assess muscle position in the vertical …

A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett
Loma Linda University Electronic Theses, Dissertations & Projects
Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.
No Chi-square determinations were statistically significant but significance in differences …

The purpose of this study was two-fold: (1) to determine the extent to which the Pima conforms to the Mongoloid master pattern, and (2) to test whether or not significant differences exist between the Pima and other Mongoloid groups which would allow discrimination.
The results of …
The Relationship Of Instructions During Labor And Relaxation, Frances Josephine Hume Lopez
The Relationship Of Instructions During Labor And Relaxation, Frances Josephine Hume Lopez
Loma Linda University Electronic Theses, Dissertations & Projects
A causal-comparative study was done in a county hospital using twenty subjects to determine if the ''unprepared" primigravida patient in active labor will experience less pain if given instructions to aid relaxation. It was hypothesized that the "unprepared" primigravida patients receiving continuous nurse attendance plus instructions to aid relaxation by (1) breathing techniques, and (2) body positions would show less evidences of pain, tension and anxiety during the first and second stages of labor than the group of patients which received only the continuous nurse attendance.
Two devices, (1) a structured observation, (2) a questionnaire with fixed-alternative questions, were used …
