Perforations might occur due to carious lesions, tooth resorption or they might be iatrogenic during endodontic treatment or in most cases they might occur during post space preparation. CASE REPORT: A 31-year-old female patient presented with a complaint of chronic pain on tooth #30 during last 6 months and sensitive to bite since a few days ago. There was a mild swelling on the gingival tissu...

BACKGROUND This study aimed to assess the diagnostic accuracy of cone beam computed tomography (CBCT) and quantitatively evaluate the morphology of mandibular first molars using CBCT. MATERIAL AND METHODS Twenty-four double-rooted mandibular first molars were evaluated by NewTom VGi CBCT. The distance from the furcation and apex to the cementoenamel junction (CEJ), diameter and thickness of c...

The purpose of this study was to compare curets with a small blade to slim ultrasonic inserts on their efficacy in removing artificial deposits from the root trunk and furcation entrance areas of mandibular molars using an in vitro model simulating a clinically closed root debridement approach. The study was conducted on 100 artificial mandibular first molars (50 right side and 50 left side) wi...

STATEMENT OF PROBLEM Sealing the perforation defect is an important factor to reduce inflammation in the area and to perform healing. Selecting the appropriate material to repair the defect is an important concern. Among the various available materials, MTA and CEM are used recently for achieving this purpose. In the current study we compare the sealing ability of these materials by evaluating ...

Introduction: The periodontal support apparatus is extremely important due to guarantee insertion the tooth. It helps with maintenance of structural resistance and reconstructive property, its loss may contribute root exposure possibility obtain an augmentation sensitivity. Thereby, this paper aimed describe a case report, using regenerative techniques in bone involving distal furcation regions...

The present investigation was undertaken to clinically and radiograplu’caily observe human p~mary teeth after pulpotomy using one-fifth dilution of formocresol. Seventyseven teeth of 59 ctuTdren, average age seven years, were treated. Seventy teeth were available for follow-up over a peHod varying from 4 to 36 months. The degree of root resorption was evaiuated comparing pairs of treated and ho...

Context: This article reviews the available evidence about the barrier membranes utilized in Guided Tissue Regeneration process to prevent the migration of unfavorable cells to the wound area. Evidence Acquisition: Available evidence about membranes properties and their different uses were reviewed, and the results of clinical and animal studies and systematic reviews were gathered. Results: A ...

The purpose of this report is to describe the histopathology of radiolucent lesions associated with pulp necrosis in primary molars. Twenty-one carious, previously untreated, primary molars with radiolucent lesions were extracted with forceps under local anesthesia. If a lesion remained attached to the root, the specimen was transferred to 10% neutral buffered formalin. The sockets were gently ...

The present study was performed to evaluate the effects of hydroxylapatite (HAP) on tissue regeneration in various types of furcation involvement. Upper premolar tooth sites of 9 beagle dogs (3-6 years old) were used. HAP particles were implanted into three types of furcation defects: Class III lesion (by Glickman) in 2nd premolar sites, artificially caused by intrafurcal suturing or spontaneou...
