Research Abstract |
According to the modification of the Industrial Safety and Health Law and Ordinance on Prevention of Hazards due to Specified Chemical Substances , the administrative level of the formaldehyde vapor concentration in working space was changed from 0. 25 ppm to 0. 1 ppm on administrative action to the evaluation of the risk of occupational diseases. In endodontic treatment, formaldehyde is commonly used for the intracanal dressing as a compound. The authors measured the formaldehyde vapor concentration in the nearby air of the simulated intracanal dressing of Formalin Guaiacol (FG). The results indicated that the root canal dressing of FG produced the formaldehyde vapor at the acceptable concentration designated by the law. There was a difference between the vapor concentration of the air collected in the summer and that in the winter. The use of dental vacuum was advocated during the root canal dressing of FG in order to decrease the vapor concentration .
