- Abstract
Endodontic sealers are used to fill the irregularities of root canals and to overcome the poor sealing ability of core root canal filling materials. Some sealers possess antibacterial effect and may eliminate microorganism left in the root canal system after completed cleaning and shaping procedures. Many studies have reported the antimicrobial activity of root canal sealers, but different techniques and methodologies have been used. The aim of this review is to review three of the most common techniques used for testing the antimicrobial effect of endodontic sealers. The Agar Diffusion Inhibitory Test, until recently, has been considered the standard method. It has some limitations and the examiner needs to consider and control many variables such as molecular weight of the material, temperature of the medium and the solubility of the endodontic sealer. The Direct Contact Test is able to measure the antimicrobial effect regardless of the solubility and the diffusability of the antimicrobial components of the sealers. A third technique is used to evaluate the disinfection of dentinal tubules using different root canal sealers. It is called Dentinal Tubule Penetration Effect. Reproducibility, functionality, reliability and simplicity are important requirements for better assessment of the antimicrobial effect of endodontic sealers. According to the recently published literature, Direct Contact Test appears to be the most reliable and is mostly used for evaluating the antimicrobial effect of endodontic sealers. For more accurate results it has been suggested to utilize more than one technique when evaluating the antimicrobial effect of root canal sealers.
