This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

There are environmental health concerns for dental health care providers chronically exposed to trace amounts of waste nitrous oxide (N2O). This study compared the effectiveness of three N2O scavenging systems, the Porter/Brown, the Accutron, and the Matrx, in actual time during use in a standardized mock dental treatment protocol that reflected clinical practice while minimizing the influence ...

The management of waste in the dental office is dictated by the federal, state, and local ordinances in force in the locale in which the office is located.
