Complete eradication of microbial biofilms and elimination of the smear layer are the key factors during endodontic treatment. Various chemical irrigants have been proposed in the literature for the same. The major setback with these chemical irrigants is that they are not bio-friendly to the dental and peri-radicular tissues. In the recent years, research to use natural products for root canal...

There is overwhelming evidence that endodontic diseases can be characterized as infectious diseases. There is no longer any question that microorganisms are at the center of the etiological causes of pulpal and periradicular pathological processes (1, 2). There are many secondary reasons contributing to tissue breakdown and endodontic failures, such as root perforations, instrument fractures, e...

AIM This study aimed to evaluate penetration of propylene glycol into root dentine. METHODOLOGY Safranin O in propylene glycol and in distilled water were introduced into root canals with and without artificial smear layer. Dye diffusion through dentinal tubules was determined spectrophotometrically. The time required for dye to exit through the apical foramen using propylene glycol and disti...

Adequate removal of the previous filling material may be pivotal to a favorable outcome root canal retreatment teeth with post-treatment periodontitis in order permit access irrigants and medicaments persistent bacteria. However, even recent technological advances, including introduction specially designed instruments, no technique has been shown predictably promote complete removal. Supplement...

The present study was conducted to determine the influence of 2 intracanal medicaments (calcium hydroxide, chlorhexidine gel 2%) when used either alone or combined on the short- and long-term sealing ability of permanent root canal fillings. Ninety human upper central incisors were divided into 4 experimental groups (n=20). All root canals were instrumented in a step-back motion and then treate...

Objective: To enhance our knowledge about the superior intracanal medicament available for reducing the interappointment pain in endodontic treatment. Methodology: Hundred symptomatic teeth presenting to the Department of Operative Dentistry, Khyber College of Dentistry were included in this study. All teeth underwent conventional root canal treatment. The canals were dried and one of the follo...

Most of periapical lesions usually result from microbial infection with oral microorganisms originating the degenerated pulp tissue. These are commonly painless and incidentally found on routine radiographic examinations. Treating these cases using non-surgical root canal is fruit innovative techniques, tools medicaments as well tendency toward minimally invasive treatment. The healing process ...

context biocompatible polymers are potentially effective for dental infections as delivery carriers of disinfectants or antibiotics into the root canal system (rcs). this study aimed to review polymeric microspheres enabling a controlled release of endodontic medicaments. evidence acquisition a literature search was carried out in the pubmed database (may 2013) using the following keywords: “po...

Inflammatory external root resorption (IERR) is a pathological phenomenon of microbial origin. This study reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (RCT). Radiographic investigation revealed periapical radiolucencies in the uppe...
