Comparison between the Outcomes of Two Platelet-Rich Concentrates on Apexogenesis in Young Permanent Incisors Requiring Endodontic Retreatment.

Platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) have been successfully used for inducing pulp regeneration in nonvital teeth. This case report highlights the difference between the outcomes of using PRF and PRP for pulp regeneration in a 13-year-old male patient, who had reported with endodontic treatment failure in his upper incisors. Gutta-percha and sealant were removed, and triple antibiotic paste (TAP) was placed in all the root canals and sealed with cavit.

Comparative evaluation of three different rotary instrumentation systems for removal of gutta-percha from root canal during endodontic retreatment: An study.

Context: Endodontic retreatment is performed in teeth with endodontic failures. The main goal of retreatment is cleaning and shaping of the root canal with removal of old root filling material. Hand instruments and rotary instruments are mainly used for removing this filling material.

Management of invasive cervical resorption using a surgical approach followed by an internal approach after 2 months due to pulpal involvement.

Invasive cervical resorption (ICR) is an aggressive and invasive form of external tooth resorption that commences in the cervical region which can be managed using either a nonsurgical, surgical or a combination of nonsurgical and surgical approach. The restoration of resorptive defects having a coronal and radicular extent can be challenging as a single material cannot be used to restore the entire defect. This case presented with Heithersay's Class 3 ICR lesion in tooth #12, which was managed initially using a surgical approach and restoration of ICR defect with a combination of resin modified glass ionomer cement, composite resin and mineral trioxide aggregate (MTA).

Background: Most often used intracanal medicament is calcium hydroxide (Ca(OH)). Removal of Ca(OH) before obturation is mandatory. Different irrigation solutions and devices were tested in the previous study for this purpose.

Assessment of Enamel Remineralisation After Treatment with Four Different Remineralising Agents: A Scanning Electron Microscopy (SEM) Study.

Introduction: Decades of research has helped to increase our knowledge of dental caries and reduce its prevalence. However, according to World Oral Health report, dental caries still remains a major dental disease. Fluoride therapy has been utilised in a big way to halt caries progression, but has been met with limitations.

Endodontic Management of a Mandibular First Molar with Radix Entomolaris and Conservative Post-endodontic Restoration with CAD/CAM Onlay: A Novel Clinical Technique.

This case report describes a novel technique of restoring endodontically treated teeth. Hidden caries causing irreversible pulpitis in a mandibular molar with Radix Entomolaris (RE) was evident. The intact occlusal surface anatomy was duplicated before preparing an access cavity to replicate the original occlusal surface in the post endodontic restoration using (Computer-Aided Design and Computer-Aided Manufacturing) CAD/CAM technique.

Fibre reinforcement in a structurally compromised endodontically treated molar: a case report.

The reconstruction of structurally compromised posterior teeth is a rather challenging procedure. The tendency of endodontically treated teeth (ETT) to fracture is considerably higher than vital teeth. Although posts and core build-ups followed by conventional crowns have been generally employed for the purpose of reconstruction, this procedure entails sacrificing a considerable amount of residual sound enamel and dentin.

Nonsurgical management of a large periapical lesion associated with an immature tooth displaying external inflammatory resorption.

Immature nonvital teeth can often be associated with periapical lesions. Presence of external inflammatory resorption can complicate the treatment plan. A 21-year-old female patient presented with a large periapical lesion in relation to teeth 11 and 12.

Apicoectomy versus apexification.

The aim was to evaluate treatment outcomes after apicoectomy and apexification in adjacent non-vital maxillary central incisors with large periapical radiolucencies, in a 10-year-old boy. The patient had complained of tenderness in the upper central incisors on mastication and gave a history of trauma to those teeth three years ago. On examination, there were found to be non-vital.

Conventionally, few-days-old pulp exposures have been treated with root canal treatment. We report four cases of traumatized, fully matured, maxillary permanent central incisors, which have been treated by Biodentine pulpotomy several days after traumatic pulp exposure. Biodentine pulpotomy consisted of pulp tissue removal to a depth of 2 mm, then capping the pulpal wound with Biodentine, followed by immediate restoration.
