Biological Markers in the Gingival Crevicular Fluid Associated with External Invasive Resorption: A Split-Mouth Cross-Sectional Study.

Introduction: This study aimed to investigate the levels of interleukin-1 receptor antagonist (IL-1RA), receptor activator of nuclear factor-κB ligand (RANKL), osteoprotegerin (OPG), interleukin-1β, osteopontin, and tissue necrotizing factor-α in teeth with external invasive resorption (EIR) in comparison to the contralateral healthy tooth of the same patient.

Methods: Twenty-nine patients with at least one tooth with EIR and a healthy tooth on the contralateral side (33 paired teeth) were included. Data on patient demographics and medical and dental history were collected.

Current Management of Dens Evaginatus Teeth Based on Pulpal Diagnosis.

Introduction: Dens evaginatus (DE) is a dental anomaly with a supernumerary tubercle projection that typically contains dentin and pulp tissue. However, the tubercle projection can fracture, exposing the dentin and potentially the dental pulp, which induces pulpal diseases. Managing DE should be primarily based on the clinical diagnosis of the pulp.

Modified Apexification Procedure for Immature Permanent Teeth with a Necrotic Pulp/Apical Periodontitis: A Case Series.

The current American Association of Endodontists clinical considerations for a regenerative endodontic procedure state that a regenerative procedure is suitable for immature permanent teeth with necrotic pulp when the pulp space is not needed for a post/core in the final restoration. Therefore, many immature permanent teeth with necrotic pulp that have sustained a substantial loss of coronal tooth structure either from caries or trauma are treated by apexification or mineral trioxide aggregate/Biodentine (Septodent, Lancaster, PA) apical barrier techniques in which no further root maturation would occur. This case series presents 10 immature permanent teeth with necrotic pulp in which a post/core was likely required in the future for adequate coronal restoration because of loss of substantial coronal tooth structure and a modified apexification procedure was used.

Treatment of Mature Permanent Teeth with Necrotic Pulps and Apical Periodontitis Using Regenerative Endodontic Procedures: A Case Series.

Introduction: Regenerative endodontic procedures (REPs) are usually used to treat human immature permanent teeth with necrotic pulps and/or apical periodontitis. Successful REPs result in the elimination of clinical signs/symptoms, the resolution of apical periodontitis, and, in some cases, thickening of the canal walls and/or continued root development with or without apical closure. REPs can restore the vitality of tissue in the canals of immature permanent teeth previously destroyed by infection or trauma.
