background and aims. the knowledge of variations in root canal morphology is critical for a successful endodontic treatment. the purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an iranian population. materials and methods. in this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...

The purpose of the study was to compare the incidence and severity of apical root resorption in patients treated with different orthodontic appliances and to evaluate the effect of treatment duration on the degree of apical root resorption. A further aim was to analyse the degree of apical root resorption in different tooth groups in patients presenting with root resorption. The sample consiste...

In this study, we aimed at studying the benefit of Urtica dioica root extract in the management of allergic rhinitis. In a randomized double blind clinical trial, 74 patients with the signs and symptoms of allergic rhinitis and a positive skin prick test were randomly divided into 2 groups. The study group was treated with routine allergic rhinitis treatment and Nettle root extract (Urtidin®, B...

Introduction: There is substantial evidence that the technical quality of root canalfilling has a significant effect on the outcome of root canal treatment. Theaim of this study was to evaluate the technical quality of root canal fillingsperformed by dental students. Methods: The records of 325 teethradiographs, treated by dental students in 2008-2009 in Babol Dental School,were selected and ev...

ABSTRACT Introduction: One of the most important steps in successful root canal treatment process is to understand the morphology of the root canal. Therefore, the clinicians should consider and release the anatomic variations in diagnosis and treatment of the mandibular and maxillary molars. Case Series: The aim of this case series is to present the successful root canal treatments completed i...

knowledge about the morphology of the root canal system is a pre-requisite for achieving a successful outcome in root canal treatment. in this report, a patient with a maxillary lateral incisor which had previously undergone orthograde endodontic retreatment for two times is discussed. the tooth had been misdiagnosed with a palatal groove or a root fracture, its prognosis had been determined to...

drip irrigation is the most efficient technique known for improving irrigation water management. a two-year study was conducted to determine the effects of drip and furrow irrigation methods on yield and quality of sugar beet in north of khuzestan. in the first year, the experimental design was a completely randomized block design with three replications. treatments were, three drip irrigation ...

this case report represents the outcome of endodontic treatment in an infected mandibular molar with periradicular periodontitis and inherent poor prognosis of root canal treatment due to severe root curvature. the tooth was successfully treated by leaving the mesial root non-obturated, the canal orifices were coronally sealed with calcium enriched mixture cement and a definitive coronal amalga...

this case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. in all represented cases, calcium enriched mixture (cem) cement is used for root-end filling. this case series demonstrates twenty cases of ir and extraoral root-end resection and filling with cem cement. all the selected teeth had a failed endodontic tr...
