Lichen (Lecanora epibryon) collected from Arshany reservation at Idleb city
was taken for screening antibacterial activity. Acetone was used as solvent for
extraction of active compounds from lichen. The activity of extract was tested
against thre
e isolated infectious bacteria (Pseudomonas sp., Salmonella sp.,
Klebsiella sp.) by cytotoxicity assay using MTT test. Acetone extract of lichen
showed antibacterial activity against all test organisms, but Salmonella sp. was
highly susceptible to the extract even at low concentration.
Dental caries is an infectious bacterial disease that results in
localized dissolution and destruction of thecalcified tissues of the
teeth. There are many dental materials which have antibacterial
effects.
The aim of this study is to evaluate th
e antibacterial effects of the
commercial types of Glass Ionomers Cement (GIC)Kaviton® CEM
and Composite Prime Dental® using at the Faculty of Dentistry in
Al- Hawash Private University (HPU), and to make comparsion
between these.
