ABSTRACT
Removal of the microbial organisms from the root canal system is a prerequisite for the successful outcome of any root canal treatment. Use of an effective intracanal medicament will assist in the disinfection of the root canal system. Intracanal medicaments have been used to disinfect root canals between appointments and reduce interappointment pain. Materials and Methods: A questionnaire survey was conducted to evaluate the knowledge, attitude, and awareness about the principal choice of intracanal medicaments among general dental practitioners and nonendodontic specialists. The questionnaire consisted of 11 questions related to intracanal medicaments in Endodontics. It was distributed to 75 general dental practitioners and 75 other specialists (nonendodontists). Results: In the present study, the authors observed that the knowledge level among the study participants was moderately satisfying. However, the need for more education of the dentists with regard to the intracanal medicaments was perceived. Discussion: Correct knowledge of intracanal medicaments would help the practitioners to decide the apt material of choice as intracanal medicaments in different clinical situations. Conclusion: The present study highlighted the need for more continuing dental education programs with active participation of general practitioners and nonendodontic specialists to update themselves.
ABSTRACT
Objective: To observe the clinical disinfection effect of root canal with non-filling medication. Methods: 36 patients who required root canal therapy(RCT) for apical periodontitis (acute or chronic) or pulp necrosis were involved in the study.RCT was completed after two visits in both groups. Non-filling medication was used as disinfection in 18 teeth of 18 patients (experimental group) while FC in another 18 teeth of 18 patients (control group) randomly at first visit.One week later,root canal was regularly filled to complete RCT.From each case, bacteria specimens were collected and identified before sealing and filling. Results: Bacteria were detected in every specimen in both groups before sealing,which were mixture of aerobes and anaerobes.One week later,only one strain was detected in one specimen of each group. Conclusion: Non-filling medication can be used as an effective disinfection to sterilize root canal.
