Influence Of Fluoride On Strength And Elasticity Of Femurs Of Rats Maintained On Diets Both Adequate And Low In Calcium, Dexter F. Beary
Loma Linda University Electronic Theses, Dissertations & Projects
The effect of fluoride on the physical properties of the rat femur was investigated by using an Instron materials tester. Experimental animals consisting of 80 female weanling rats were employed. These were divided into two major groups of 40 rats each. Group I received adequate calcium in the diet and Group II received a low calcium (0.1%) diet. Group I and II were divided into five subgroups, the first subgroup being used as the control. Each of the other four subgroups was given a different dosage level of fluoride in their drinking water as follows: the second subgroup received Hereford, …
An Odontometric Study Of Five Contemporary Western United States Indian And Alaskan Eskimo Groups, John A. Matis
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 Study Of The Face And Dentition Of Several Contemporary Western United States And Alaskan Eskimo Groups, Robert C. Parkard
A Cephalometric Study Of The Face And Dentition Of Several Contemporary Western United States And Alaskan Eskimo Groups, Robert C. Parkard
Loma Linda University Electronic Theses, Dissertations & Projects
A total of 223 cephalometric radiographs selected from six contemporary western United States and Alaskans native groups were analyzed by use of the Bjork cephalometric analysis. Those native groups selected were the Eskimos, Apaches, Navajos, Papagos, Pimas and Mayos. Approximately thirty to forty natives from each group were used in the study with ages ranging from thirteen to thirty-five years. The majority were in the fifteen to twenty year age range.
All data was submitted to various statistical analyses to establish a mean, standard deviation, and other relevant values for each of the native groups and to compare these values …
