Aim: To evaluate and compare the efficacy, cleaning ability of hand and two rotary systems in root canal retreatment.
Methodology: Sixty extracted premolars were retreated with following systems: Group -ProTaper Universal retreatment files, Group 2-ProFile system, Group 3-H-file. Specimens were split longitudinally and amount of remaining gutta-percha on the canal walls was assessed using direct visual scoring with the aid of stereomicroscope.
Article Synopsis
- Study highlights the importance of using effective antibacterial agents for successful endodontic treatments by comparing silver diamine fluoride (SDF) and chlorhexidine gluconate (CHX) against bacterial infection in root canals.
- A total of 44 teeth were prepared and inoculated with Enterococcus faecalis to test the efficacy of the two agents in reducing bacterial colonies.
- Results indicated that both SDF and CHX were significantly more effective in sterilizing root canals compared to control groups, suggesting SDF as a viable option for irrigation in endodontics.
Aim: The aims of this study were to determine the effect of saliva and blood contamination on the shear bond strength of self-etching adhesive to enamel and dentin; and, to compare the difference in bond strength due to contamination beforeand after application of the self-etch adhesive.
Materials And Methods: 40 human mandibular molars were wet ground on both buccal and lingual surfaces to prepare flat superficial enamel and dentin surfaces. They were randomly divided into two groups (n = 40) based on the substrate (enamel and dentin).
