Objective: To determine increase in root(s) length and thickness and closure of apical foramen in patients undergoing revascularization of immature, permanent, necrotic teeth Material and Methods: This study was conducted at outpatient department of Operative Dentistry, Pakistan institute of medical sciences (PIMS), Islamabad, from 22 January 2011 to 22 January 2013. All the patients were asses...

background and aims. triple antibiotic paste (tap) is widely used in endodontics for root canal disinfection, particularly in regenerative procedures. the aim of this in vitro study was to evaluate the antimicrobial effects of different concentrations of tap at 1-, 2-, 3-, and 4-week intervals on mature enterococcus faecalis biofilm. materials and methods. a total of 287 extracted one-rooted hu...

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...

objectives: this study aimed to assess and compare the apical sealing ability of herofill® soft-core system and lateral condensation technique in fine curved canals using the fluid filtration method. materials and methods: forty human mesiobuccal root canals of mandibular first molars with 25° to 40° curvatures were instrumented to an apical size 30/0.04. roots were randomly assigned to two exp...

removal of smear layer and disinfection of canals are important objectives of teeth root canal cleaning. in order to achieve this purpose, rinsing substances, intra canal drugs as well as ultrasound are used. today, use of laser to remove smear layer and to disinfect root canals has increasingly attracted the attentions. till now different lasers such as co2, nd:yag, er:yag, er,cr:ysgg have bee...

The success of endodontic treatment is highly dependent on the adequate three-dimensional cleaning, shaping, disinfection, and obturation of the root canal system. It is universally accepted that the correct determination of the working length (WL) is one of the crucial steps in the process of a successful treatment. It is believed that root canal preparation and filling should be kept inside t...

The objective was to evaluate the clinical efficacy of chemomechanical preparation of the root canals with sodium hypochlorite and interappointment medication with calcium hydroxide in the control of root canal infection and healing of periapical lesions. Fifty teeth diagnosed with chronic apical periodontitis were randomly allocated to one of three treatments: Single visit (SV group, n = 20), ...
