JOURNAL FREE ACCESSA preoperative presumptive diagnosis of ameloblastoma is sometimes made in the light of available clinical and radiological data, which are generally not very characteristic. The final diagnosis can only be made on the basis of histologic features. In this paper, a case of ameloblastoma diagnosed preoperatively by fine-needle aspiration cytology is presented and the potential value of this technique for diagnosing oral lesions is discussed.View full abstractDownload PDF (6785K) -
A Method for Contrasting of Collagen FibrilsCengiz KOCKAPAN1989 Volume 31 Issue 4 Pages 570-576

JOURNAL FREE ACCESSAn electron microscopic investigation was undertaken to study a method for contrasting predentine collagen fibrils by their cross-striations after exposure of tissue to chromium solution for various periods. After 1 day of treatment, the cross-striations of collagen fibrils in predentine were clearly visible. The contrast of the cross-striations increased with longer periods of exposure to chromium. This method makes it possible to study the orientation of crystallites as well as collagen fibrils.View full abstractDownload PDF (7866K) -

JOURNAL FREE ACCESSSurgical correction and osteoplasty were carried out in one case of prolonged and three cases of recurrent forward dislocation of the temporomandibular joint, two of the patients in the latter cases having mental disorders and one having a cerebral lesion. A hockey-stick-shaped preauricular incision was made, ending in the hair-bearing part of the temple. Then, the temporal fascia and muscle were divided anteriorly from the temporal bone. In two aged patients, a fragment of the zygomatic arch was pushed out and down, joining under the articular tubercle. In two younger patients, the cortical bone of the mandible was separated by sagittal split-ramus osteotomy for mandibular prognathism, and two graft blocks removed from the iliac bone were implanted between the root of the posterior zygomatic arch and the anterior cut-edge of the articular tubercle. In 3 of the 4 patients, the fragments or grafts were fixed by means of ligation using wire so as to make contact with the root of the posterior zygomatic arch. There was no recurrence of dislocation during a period of 2-5 years after surgery.View full abstractDownload PDF (9273K) -

JOURNAL FREE ACCESSThe authors devised a new method for making a maxillary prosthesis with a hollow obturator, which was named the Balloon Technique.
This new technique has a number of advantages over the conventional method in that it not only facilitates the molding of a soft plastic hollow obturator in a single process, but also simplifies the trial fitting of the completed obturator. Furthermore, it makes possible firm adhesion of the hollow obturator and the denture base by the hot-melt method while the denture base resin is cured. Finally, the completed maxillary prosthesis is extremely light.View full abstractDownload PDF (8643K) -

JOURNAL FREE ACCESSIn order to clarify the toxicity of the antineoplastic drugs, bleomycin (BLM), peplomycin (PEP) and cis-diamminedichloroplatinum (CDDP), which are commonly used to treat head and neck cancer by simultaneous administration, the semiacute toxicity of each of these drugs in rats was studied as an initial step. Body-weight change, general behavior, red blood cell count (RBC), white blood cell count (WBC), serum biochemistry (s-GOT, s-GPT, BUN, GLU, ALB, TP), A/G ratio, relative organ weight and histopathological features were determined. BLM and PEP given by ip administration once a week produced severe diarrhea, decreased diet consumption, emaciation, piloerection and loss of hair, enhancements of RBC and WBC, several changes in serum biochemistry, proliferation and mitosis of epithelial cells in the forestomach and occasional granular and vacuolar degeneration in the liver. CDDP administered in the same manner produced a significant decrease of WBC, several changes in serum biochemistry parameters especially BUN, an increased focal-segmental mesangial matrix in the glomeruli and vacuolar degeneration of epithelial cells of the convoluted tubule of the kidney.View full abstractDownload PDF (8272K) -

JOURNAL FREE ACCESSA survey of 303 six- to fifteen-year-old Proto-Malay children was carried out in Selangor, West Malaysia. The examinations were carried out using a chair-table and natural daylight. Periodontal status was assessed using the Community Periodontal Index of Treatment Needs (CPINT). The findings revealed a generally low prevalence of periodontal disease affecting only 25.08% of the sample examined. Of these, 15.72% were found to have a score of 1 (bleeding of the gingiva), while 9.36% had calculus on the tooth surface. In terms of treatment needs, 24.75% required dental health education. The relationship between these findings and the possible causes are discussed.View full abstractDownload PDF (864K)
