Evaluation of antibacterial effects of different intracanal medicaments on Enterococcus faecalis in primary teeth: An in vitro study.

Objectives: Successful endodontic therapy is based on the reduction of infecting bacteria by cleaning, shaping, and disinfecting of the root canal system, thus the use of intracanal dressing is necessary for optimal success of root canal treatment. This study was designed to evaluate the effect of chitosan and propolis as intracanal medicaments against Enterococcus faecalis compared to calcium hydroxide in primary root canals.

Material And Methods: Ninety-six extracted primary second molars were collected.

The effect of chlorhexidine-thymol and fluoride varnishes on the levels of in saliva in children aged 6-8 years.

Background: Streptococcus mutans is considered as the main pathogenic factor for initiation and progression of dental caries. Fluoride is one of the most effective agents used to control caries. Chlorhexidine (CHX) is the most antimicrobial agent against S.
