abstract background and aim: increased rate of micronucleus in buccal mucosa cells and its correlation with carcinogenesis is worth consideration. recently, occupation in dental laboratories has been proposed as a predisposing factor. therefore, the present study aimed to evaluate the effect of occupational exposure on buccal mucosa cells of dental laboratory technicians. materials and methods:...

This article presents a single onlay case that was significantly enhanced through a detailed communication process between the clinician and the laboratory technician. By using colour slides as part of the dentist-technician communication process, the author found that the technician was better able to create an esthetic, accurate and successful restoration that addressed the patient's needs.

introduction: marginal adaptation of cast restorations is essential for their long-term success. as dentists usually assign ditching of dies to laboratory technicians, and ditching has a significant effect on marginal adaptation, the aim of this study was to compare ditching by laboratory technicians and standard approach on marginal adaptation of cast restoration. materials and methods: in thi...

background: the aim of this study was to evaluate risk of needle stick and sharp injuries (nsi) and exposure to blood borne pathogens, among laboratory technicians. methods: 213 self-reporting questionnaires were distributed among the laboratory technicians who were working at three educational hospitals in tehran. a total of 193 laboratory personnel completed the questionnaire. results: 69.9% ...

background: sputum smear examination is the basis of diagnosis of tuberculosis and quality control for the correct diagno­sis of tuberculosis is necessary. this study was a method survey and performed with 930 smears with the aim to compare the confidence rate of sputum smear examination reported by one laboratory technician with the findings reported by two techni­cians in a tuberculosis scree...

A laboratory technician developed leptospirosis following accidental inoculation, despite prompt administration of parenteral penicillin by an accepted regimen of post-exposure prophylaxis. Another technician was similarly exposed and was given doxycycline; no illness or serological conversion followed. The implications of these cases are discussed and recommendations made for post-exposure che...

With conventional fixed dental prostheses, the interim restoration is a valuable diagnostic tool in the evaluation of esthetics and function. To achieve predictable definitive esthetic results, information about the subgingival and the supragingival contour of a properly designed restoration should be communicated to the dental laboratory technician. The technique described enables the accurate...
