Tihis study was undertaken to evaluate by a number of different scoring methods the health of the gingiva around temporary acrylic crowns. A total of 50 crowns were studied from male patients at the Prosthetics Clinic of Boston University School of Graduate Dentistry. It was found that the health of the gingiva did not depend on the location of the margin of the temporary crown, i.e. whether the crown mar.gin was subgingival ori at the gingival margin. The accumulation of caltulus on the crowns was found to be r.elated to the smoothness of the crown surface, and also to the or.al hy.g1ene ability of the patient. The best index for evaluating gingival health was found to be that developed by Orban and Stallard (1968). This method involved obtaining a sample of tissue, with the use of a curette, from the gingival sulcus. The resulting biopsy specimen was placed on a glass slide, fixed, and stained by hematoxylin and eosin. This was examined under the microscope and the biopsy evaluated in regard to the numbers...
