The patient's desire to preserve their natural dentition is increasing constantly; therefore, nowadays dentists have to treat teeth that once would have been extracted. Using endodontics, periodontics and restorative dentistry techniques, we can maintain these teeth on the arches in whole or in part and they can be used as independent units of mastication or as abutments in simple fixed bridges...

Endodontic failures associated with poor quality of endodontics respond favorably to retreatment. Nevertheless, under certain clinical conditions, apicoectomy should be the preferred procedure. A retrospective survey of 200 roots that were referred for apical surgery revealed that 83% of the roots were inadequately obturated, including 8.5% with no root canal filling at all. In 49 of the roots ...

Nonhealing periradicular pathosis associated with endodontically treated teeth is customarily managed by revision (retreatment). Root-end resection is less often the first choice of treatment. Objectives. This prospective randomized study compared the outcome of retreatment and surgical intervention in root cana[ treated teeth with nonhealing periradicular pathosis. Study design. One such tooth...

OBJECTIVE To achieve the required goal of optimally sealing the apical section and the root-canal when performing an apicoectomy, the authors decided to use the CO2 laser as an additional aid. SUMMARY BACKGROUND DATA The CO2 laser has previously shown to have an excellent sealing effect on dentin surfaces. METHODS In this in vitro study, the authors examined the effects of CO2 laser applica...

Apicoectomy failure is generally related to inappropriate marginal sealing of the retrocavity, which allows percolation of microorganisms and their products from root canal system to periapex. This study evaluated tubular penetration of canal sealers and marginal permeability after retrocavity irradiation with Er;Cr:YSGG laser and retrofilling with MTA or cyanoacrylate. Twenty-two single-rooted...

introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...

PURPOSE The purpose of this study was to evaluate the effect of submucosal dexamethasone injection to control postoperative pain and swelling in apicectomy of maxillary anterior teeth. METHODS A randomized, controlled trial comprising 60 adult patients (68.3% male, 31.7% female) with no local or systemic problems was conducted. Patients were randomly divided into two groups: Group A was given...

Dental occlusion represent the function of dentomaxillary system at which realization participate all the components of that system holding the equilibrium between them. Setting up the treatment with dental bridges in partial edentuluous is rule by some principles that have aims like restore the morphology and functions change by edentuluous condition and also prevention disorders of remaining ...
