There is no universal protocol for diagnosing, treating and managing cracked teeth. The purpose of this survey was to investigate the use of traditional methods of crack detection and to explore how treatment decisions were made using an intrapulpal crack classification. The electronic survey was sent to 1115 active members of the American Association of Endodontists (AAE) and The Digital Office (TDO™) community. Comparisons were assessed using logistic or repeated-measures regression. The most often used diagnostic method was probing. When the crack involved one wall, 85% of respondents would complete root canal therapy > 50% of the time or always. For two or more walls, the percentage dropped to 44%. When the crack involved the floor or orifices, 60% would not complete treatment. For necrotic teeth, 36% of respondents preferred extraction as opposed to 3% if vital. This survey illustrated the anecdotal nature of detection, diagnosis and management of cracked teeth.

"During the past twenty-five years the writer has taught in various types of buildings, ranging from army barracks to buildings, which, when built, represented the very best in modern school planning. Out of this experience comes a knowledge of the effect the physical plant actually has as a determining factor in the teacher's ability to give proper instruction. A teacher may do his best with the equipment and facilities offered without accomplishing the same satisfactory results that could be possible under better conditions. The realization that the value of the physical plant is important has created a desire to make a study of the modern trends in school architecture and planning. From personal experience and research it is proposed that in this article ways and means be suggested whereby existing facilities might be improved at Sealey Memorial School"--Introduction. / "July 15, 1949." / Typescript. / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Arts under Plan II." / Advisor: R.
