E. C. COMBE Dental materials: 1982 literature review Part 1 J. Dent 13, (1985) I-40. This report which is to be presented in two parts, reviews published papers on based on literature dental materials, for 1982. In this part the following topics are considered: metals, including dental amalgam and casting and wrought alloys; ceramics, implants and aspects of dental biomechanics.
JOYSTON-BECHAL S. The effect of X-radiation on the susceptibility of enamel to an artificial caries-like attack in vitro J Dent 13, (1985) 41-44. The aim of this study was to investigate the effect of radiation on the susceptibility of enamel to the development of artificial caries-like lesions in vitro. Results showed that lesions in the test specimens which had received a dose of 7000 rad were significantly shallower than those in the untreated controls (P
DUNNE S. M. and CLARK C. G. The identification of the medically compromised patient in dental practice J. Dent 13, (1985) 45-51. Medical histories were obtained from 130 dental outpatients by questionnaire. A total
of 109 medical conditions were recorded. The dental records of 50 of these patients, examined selected at random, were retrospectively and compared to the questionnaire responses. Twenty-eight omissions were found rn the dental records, 1 1 of which were potentially serious, while 3 were potentially life threatening. These results indicate the ease by which relevant medical details can be missed in a hurried interview, and illustrates the usefulness of a simple self-answering questionnaire.
SANTINI A. H. calcium Intraoral comparison of hydroxide (Calnex) alone and in combination with Ledermix in first permanent mandibular molars using two direct inspection criteria J. Dent 13, (1985) 52-59. The efficacy of a calcium hydroxide in preparation (Calnex) alone and combination with a proprietary corticosteroid/antibiotic medicament (Ledermix) has been tested as a pulp dressing using intraoral comparisons in human first permanent mandibular molars which were clinically diagnosed as having a chronic partial pulpitis associated with a painful active carious lesion. A total of 260 teeth in 130 patients were treated. The patients were divided into two age groups, those less than 7.5 years and those older than 13 years at operation, chosen to represent patients with teeth which were, respectively, newly erupted with incomplete apices and mature with closed apices. Assessment of 174 teeth in 87 patients was undertaken by direct inspection for bridge formation at the exposure sate and for an associated vital bleeding pulp, at a six-month postoperative period. There was no significant difference in the results obtained with calcium hydroxide alone (Calnex) and with calcium hydroxide (Calnex) plus a proprietary corticosteroid (Ledermix) in either age group, though the association
