    Author(s): Ghassan Abdul-Hamid Naji* and Layth Taher Omer

    Introduction: Due to its proven antimicrobial efficiency, bergamot essential oil was incorporated into dental stone mixture to enhance the material by yielding a disinfected cast, however such property enhancement should not be accompanied by jeopardizing others in order to make sure of the material’s usability. Aims: The study was aimed to evaluate some properties of type III dental stone that include diametral tensile strength, initial setting time and linear setting expansion after the incorporation of bergamot essential oil. Materials and Methods: A total of 90 specimens, 30 for each test with dimensions of 20 ± 0.2 mm in diameter and 40 ± 0.4 mm in thickness for diametral tensile strength test, 70 mm in diameter at top, 60 mm in diameter at bottom and 40 mm high for initial setting time test ..
