摘要:

Abstract—Twenty‐four rats were divided into groups that received cumulative dosages of 500, 750 and 1000 rads of fractionated megavoltage X‐irradiation. Animals sacrificed three days post‐irradiation showed marked acinar atrophy but no vascular or ductal changes and isolated areas exhibited more severe damage, predominately vacuolation, apoptosis and total cell destruction. The severity of the changes mirrored the total cumulative dosage. Animals sacrificed 14 days post‐irradiation showed a marked return to pre‐irradiation morphological status.Greater recovery was noted in the 1000 rads dose than in the lower dose groups. A marked increase in vascularity reflected the recovery process. Auto‐radiographic estimations using (3H) leucine supported the morphological changes only in the 1000 rad groups and these showed the least uptake at three days, but by 14 days exhibited the greatest increase—far above the level of control animals. Apoptosis apparently enables the tissues following repair of reversible damage to return to normal ce

摘要:

Abstract—The management of the patient with a cleft lip and palate is best accomplished by a multi‐disciplinary team approach provided at a paediatric hospital. The role of periodontal treatment is discussed within such a framework. The implications are mainly related to altered soft tissue morphology without true loss of periodontal attachment. The rationale of plaque control and surgical intervention is discussed and the close relationship between periodontal and prosthetic considerations in treatment planning is highligh

摘要:

Abstract—The spectral distributions of eight colour‐matching lamps were measured and compared with those of normal fluorescent and dental operating lamps. The correlated colour temperatures of the former ranged from 3700 to 6900 K while the CIE colour rendering index ranged from 80 to 98. When compared with the spectral distributions of the daylight phases D48and D65the colour‐matching lamps generally had insufficient or excessive intensity in one or more regions of the visible and ultra‐violet spectra, but they are preferable to non‐daylight fluorescent or dental operatory lamps for ceramic shade

摘要:

Abstract—Although oral syphilis is uncommon, it is, however, a potential health risk to dentists who are usually unfamiliar with this clinical entity. The following case report highlights the problems that could arise when dentists are confronted with clinical cases of secondary syphilis with oral affectio

摘要:

Abstract—Analysis of brews of a selection of teas available in Australia using the fluoride ion‐selective electrode gave after a five‐minute infusion an average fluoride level of (1.34 ± 0.17 ppm) F. Brews of two brands of tea contained>2 ppm F; using fluoridated water a cup of tea made with one of these brands may contain 0.5 mg F. Its potential significance for young children on fluoride supplements should be reco

Abstract—A case of cat scratch disease which confronted a general dental practitioner as a submandibular swelling is described. Other interesting aspects of the case include a fluctuating response to antibiotic therapy and a presumed appearance of the disease within the immediate family of the affected chil

摘要:

Abstract—A case of acute ulcerative gingivitis (AUG) with pericoronitis is presented showing how differential dark‐field microscopy can be used to aid in diagnosis and monitor therapy. The AUG site showed a unique flora with dark‐field microscopy, which in this case was shared by the pericoronitis lesion. Metronidazole therapy resulted in a marked change in the flora of both sites. Four days following therapy both sites showed a similar flora to a normal healthy site which remained unaltered throughout the trea

摘要:

Abstract—The application of the posterior segmental maxillary osteotomy to the problem of the palatally impacted cuspid tooth was studied in 12 patients so treated. The degree of success was based on several criteria, including stability, periodontal health, occlusion and individual response to treatment. Existing literature is reviewed and discussed in the light of the present finding
