STUDY DESIGN To qualify for the study the general dentists had to perform some endodontic treatment and to refer some to endodontists. Success was defined as the(More)
The thymus-dependent lymphocytes (T cells) were enumerated in the peripheral circulation of 38 patients with histologically demonstrated squamous cell carcinoma of the head and neck. We have previously shown that this "total" T-cell count correlates well with degree of tumor involvement. A lower percentage of T cells were shown in patients with more(More)
Otitis media (OM) continues to be a major health problem of children in the United States. The role of environmental tobacco smoke (ETS) as a predisposing factor has not been completely discerned. This study and discussion is an investigation and review of the influence of passive cigarette smoking on OM in children, and its effect on the practice of(More)
Conventional closure of surgical defects in skin may cause unsightly protrusions (dog ears). Fusiform excisions with angles of 30 degrees or less reduce protrusion but may require excision of larger volumes and lengths of healthy skin and subcutaneous tissue than may be desirable. M-plasties reduce these requirements while still allowing use of 30 degrees(More)
Various techniques have been described in the literature for auricular reconstruction after resection of both benign and malignant tumors of the auricle. Since 1981, I have performed simple wedge resections of the auricle as treatment for both basal and squamous cell carcinomas. A 4-mm margin on the former lesions and a 6-mm margin on the latter lesions(More)
The section of the cat's mesotympanum, denuded of mucosa, to Silastic and gelatin film was studied and compared with the contralateral control ear, which was also denuded of mucosa. The ears were studied by horizontal pathological sections taken one, two, four, and six months post-lympanotomy and insertion of either gelatin film or Silastic. The Silastic,(More)
The purpose of this study was to compare the number of rotations to fracture of nickel-titanium (NiTi) rotary files operated at different speeds and different angles. We used 60 Profile NiTi rotary files, size 25 (30 each of 0.04 and 0.06 taper), operated at speeds of 350 or 600 rpm at angles of 25, 28, and 33.5 degrees. The time to fracture and number of(More)
