Abstract

Introduction: Liquid evaporation of MMA and toxic side effects including the liver complications and allergic reactions among the technicians of dental laboratories these reports emphasize to need the usage of protective methods in order to reduce the direct exposure with this material. Objective: This research was performed to determine the METHANOL level in dental laboratory technicians, urine who were in direct contact with the MMA compared with the control group. Materials and Methods: In this cross sectional study, urine sample were obtained from 30 dental laboratory technicians of Rasht and Lahijan province (IRAN) before and after working with MMA and 30 normal individuals who were not direct /indirect contact with MMA (were selected) as control group. Urine METHANOL levels of both groups were determined by gas and paper chromatography methods. Obtained data were analyzed by Student’s t-test. Results: Mean METHANOL level in the individuals of experimental group (1.3 µm/Lit) was greater than the control group (0.9 µm/Lit) that revealed a significant difference (P=0/032). Mean METHANOL level in urine after the end of working period (1.5 µm/Lit) was significantly greater than the level of it at the starting to work by it (1.3 µm/Lit). There was no relationship between the length of working years and the level of urine METHANOL. Conclusion: Significant increase of mean METHANOL level in urine after finishing the work and the significant difference of METHANOL level among the dental laboratory technicians compared to the control group emphasis to usage of protective methods such as the presence of appropriate ventilation, using mask, gloves or absorbent filters of MMA dusts. These protective methods could be effective in the increase in working safety in DENTAL TECHNICIANS.
