Over a 14-year period, 1525 biopsied oral lesions of pediatric dental patients aged 1-19 were submitted for diagnosis. The lesions were categorized into 5 groups resulting in the following epidemiological findings. Mucoceles, occurring predominantly on the lower lip among whites and females were the most common among the inflammatory~reactive lesions.(More)
This study investigated the effect of doxycycline irrigation on wound healing and the apical seal of three filling materials. Part 1: 220 extracted teeth received root canal therapy followed by root resection (2 mm) and ultrasonic root end preparations (3 mm). Groups of 20 were irrigated with saline, citric acid, or doxycycline and filled with amalgam,(More)
Cancer patients inevitably experience situations in which their sense of personal control is diminished. Identifying the strategies used by these individuals to maintain or regain control can be an important component in the planning of care. This study examined the relationship between levels of perceived personal control and the needs for hope and(More)
Tissue specimens submitted to an oral pathology biopsy service during a 17 1/2-year period were studied to determine the types of diagnoses rendered, the general types of pathological processes represented, and the epidemiologic distribution of patients. A total of 15,783 cases were studied. Normal structures were observed in 480 cases, mostly dental(More)
Most histological laboratories are required at some time or other to stain tissue sections with one or more of the trichrome or polychrome staining techniques. Among the most common ones employed are Masson's Trichrome, Mallory's Aniline Blue Collagen Stain and Gomori's One-Step Trichrome Method. Since these are empirical procedures rather than specific(More)
Tumor necrosis factor-alpha (TNF-alpha) is a macrophage-derived cytokine elicited during cellular responses to various microbial infections. TNF-alpha exerts direct cytotoxicity toward some tumor cells in vitro and produces hemorrhagic tumor necrosis in vivo. In human promyelocytic HL-60 leukemia cells, human recombinant TNF-alpha (rTNF-alpha) exhibits a(More)
Fragments recovered from the burned wreckage of a gasoline truck and thought to be parts of teeth were confirmed as such after they were examined with a scanning electron microscope. The appearance of the fragments was compared with previously published descriptions of teeth which had been incinerated under laboratory conditions and also examined by(More)
The effect of guided tissue regeneration procedures on the healing of osseous defects was studied in Sprague-Dawley rats. A full thickness flap was reflected and two 5 mm defects were made in the calvaria of 17 rats. A resorbable membrane was placed over one defect in each animal, while the remaining defect served as a control. After 3, 5, or 7 wk, healing(More)
