✦ Synopsis

Combinations of rosin and zinc are used in den-zinc concentrations. The purified resin acids (isopimaric, letistry as components of periodontal dressings and cements vopimaric, and neoabietic acid) were more toxic than the and as root canal sealers. The composition and properties of natural rosins. The contents of these resin acids might exrosins differ largely depending on source and refinement plain the difference in toxicity of the rosins tested. It is conprocesses. Rosin (colophony) is composed of approximately cluded that rosin and zinc are not to be considered inert 70% resin acids. In order to study the toxic effects of different compounds and that the cytoprotective effects of zinc and natural rosins and purified resin acids and the detoxifying its role in dentistry products merit further investigations. effects of zinc, these compounds were analyzed and tested
