Relationship Between Exposure Levels of Dust Polymethyl Methacrylate And Characteristics of Workers With Subjective Respiratory Complaints in Dental Engineering Laboratory, Dki Jakarta Region in 2021

The manufacture of dentures, especially from polymethyl methacrylate affects the health of workers, especially those related to breathing. The manufacture produces dust of various sizes. The effects of exposure to dust cause discomfort at work and have a negative impact on health. This research objective was to determine the relationship between exposure to polymethyl methacrylate and subjective respiratory complaints.
