Use of Cone-beam Computed Tomography during Retreatment of a 2-rooted Maxillary Central Incisor: Case Report of a Complex Diagnosis and Treatment
A double-rooted maxillary incisor is an extremely rare anatomic variation. Only a few case reports describe this abnormal anatomy. In recent decades, cone-beam computed tomographic (CBCT) imaging has become more common for endodontic purposes. This case report describes the retreatment of double-rooted maxillary central incisors using CBCT imaging. In 2012, a 20-year-old man was referred to our department because of asymptomatic periapical lesions in teeth #8, #9, and #10. During the evaluation of a periapical radiograph, a rare anatomic variation, in the form of an additional root of tooth #9, was detected, and it was imp...

Large Reactional Osteogenesis in Maxillary Sinus Associated with Secondary Root Canal Infection Detected Using Cone-beam Computed Tomography
This report describes the radiographic findings of 4 asymptomatic clinical cases of large reactional osteogenesis in the maxillary sinus (MS) associated with secondary root canal infection detected using cone-beam computed tomographic (CBCT) imaging. Apical periodontitis, a consequence of root canal infection, may lead to a periosteal reaction in the MS and osteogenesis seen as a radiopaque structure on imaging scans.

Quantifying Coronal Tooth Discoloration Caused by Biodentine and EndoSequence Root Repair Material
Mineral trioxide aggregate (ProRoot [PR]; Dentsply, Tulsa, OK) has been shown to have high rates of success in various endodontic applications. A major drawback is its tendency to discolor dentin. Two new bioceramics (BD, Biodentine [BD]; Septodont, Saint Maur des Fosses, France; and EndoSequence [ES]; Brasseler, Savannah, GA) have been developed that claim to not discolor teeth. The aim of this study was to compare tooth discoloration between these 3 materials. (Source: Journal of Endodontics)

An Evaluation of Apical Cracks in Teeth Undergoing Orthograde Root Canal Instrumentation
Dentinal damage and cracks induced by orthograde preparation methods have been reported in studies using extracted teeth. The purpose of this in situ investigation was to evaluate dentinal cracks in nonextracted teeth after final instrumentation. The null hypothesis is that orthograde root canal instrumentation will have no effect on crack initiation in teeth retained in the natural periodontium. (Source: Journal of Endodontics)

A Comparison of Apical Bacterial Extrusion in Manual, ProTaper Rotary, and One Shape Rotary Instrumentation Techniques
Apical extrusion of irrigants and debris is an inherent limitation associated with cleaning and shaping of root canals and has been studied extensively because of its clinical relevance as a cause of flare-ups.

Attachment Ability of Human Apical Papilla Cells to Root Dentin Surfaces Treated with Either 3Mix or Calcium Hydroxide
Tissue regeneration and root continuation are the ultimate goals in regenerative endodontics. Apical papilla cells (APCs) have been hypothesized to play roles in those processes. Therefore, preservation of cell vitality and promoting initial cell attachment seem to be crucial steps. The purposes of this study were to investigate the attachment ability and morphology of viable human APCs by using fibronectin immunofluoresence, alamarBlue assay, and scanning electron microscopy, when APCs were grown on human root dentin surfaces treated with 3Mix or calcium hydroxide (Ca(OH)2) at different concentrations.

Negotiability of Second Mesiobuccal Canals in Maxillary Molars Using a Reciprocating System
The aim of this prospective case series report was to assess the frequency in which the Reciproc R25 instrument (VDW, Munich, Germany) is able to scout and reach the full working length (WL) in second mesiobuccal (MB2) canals from maxillary molars. Conventional hand file negotiation was used as the reference technique for comparison. Maxillary molars (270 first molars and 71 second molars) were included in this study. After local anesthesia, the tooth was isolated with a rubber dam, and traditional straight-line access was made. (Source: Journal of Endodontics)

Evaluation of ProRoot MTA, Biodentine, and MM-MTA on Human Alveolar Bone Marrow Stem Cells in Terms of Biocompatibility and Mineralization
Stem cell technology has been a great hope for the regeneration of cells of pulp-dentin complex and dental structures together with surrounding bone and periodontium. The main challenge in the regeneration process is a successful combination of stem cells and efficient inductors such as inductive biomaterials. In this regard, today, manufacturers propose novel tooth filling materials. The current study was aimed to compare the effect of ProRoot MTA (Dentsply Tulsa Dental, Tulsa, OK), Biodentine (Septodont, Saint Maur des Fossés, France), and MM-MTA (Micro-Mega, Besançon Cedex, France) on the cell viability, hard tissue d...

Pulp and Periodontal Regeneration of an Avulsed Permanent Mature Incisor Using Platelet-rich Plasma after Delayed Replantation: A 12-month Clinical Case Study
Numerous publications have reported revascularization of necrotic immature permanent teeth, but the regenerative potential of pulp in mature teeth has rarely been considered. Platelet-rich plasma (PRP) meets many requirements of a scaffold for regenerative endodontics. To the best of our knowledge, no clinical study has evaluated PRP for endodontic regeneration in a mature avulsed tooth. The present case evaluated PRP for pulpal regeneration in an avulsed mature incisor (>8 hours extraoral dry time) of an 11-year-old boy after delayed replantation. (Source: Journal of Endodontics)

The Effects of Endosequence Root Repair Material on Differentiation of Dental Pulp Cells
Pulp capping techniques aim at preserving the vitality of pulp tissue, thus avoiding more invasive endodontic procedures. Endosequence Root Repair Material (ERRM; Brasseler USA, Savannah, GA) has been recently introduced as a potential pulp capping material. It is hypothesized that ERRM promotes the healing of dental tissue, thus maintaining the integrity and vitality of the pulp after pulp capping procedures. However, the exact mechanism by which ERRM affects the pulp after pulp capping procedures is still unknown. (Source: Journal of Endodontics)

Florid Cemento-osseous Dysplasia: A Case of Misdiagnosis
Florid cemento-osseous dysplasia (FCOD) belongs to the group of fibro-osseous lesions in which normal bone is replaced by fibrous connective tissue and calcified cementum tissue of the avascular type. Among the various types of fibro-osseous lesions, FCOD is 1 of the most commonly encountered diseases in clinical practice and may involve 3 or 4 of the quadrants. FCOD is located in the periapical regions of teeth, and the lesions are predominantly radiolucent (osteolytic phase), become mixed over time (cementoblast phase), and ultimately become radiopaque (osteogenic phase) with a thin radiolucent peripheral halo.

Conservative Nonsurgical Treatment of Class 4 Invasive Cervical Resorption: A Case Series
External cervical resorption, also called invasive cervical resorption (ICR), is a pathological process difficult to diagnose that causes a progressive replacement of dentin by granulation tissue and results in complete tooth destruction.
