A Case of SAPHO Syndrome with Endodontic Implications and Treatment with Biologic Drugs
SAPHO syndrome (SS) is an autoinflammatory disease characterized by synovitis, acne, pustulosis, hyperostosis, and osteitis. Among the sites affected by the osteoarticular manifestations of SS are the anterior chest wall and the mandible. The etiology of SS is still unknown; theories advocate a genetic predisposition and an infectious cause in association with disorders of the immune system. (Source: Journal of Endodontics)

CXC Chemokine Receptor 4 Is Expressed Paravascularly in Apical Papilla and Coordinates with Stromal Cell–derived Factor-1α during Transmigration of Stem Cells from Apical Papilla
Stem cells from the apical papilla (SCAPs) at the apex may be attracted into the root canal space as a cell source for pulp-dentin regeneration. To test this possibility, we used in vitro transmigration models to investigate whether SCAPs can be chemoattracted by the delivery of the chemotactic cytokine stromal cell–derived factor-1α (SDF-1α).

Bioactivity of a Calcium Silicate–based Endodontic Cement (BioRoot RCS): Interactions with Human Periodontal Ligament Cells
Tricalcium silicate–based materials are recognized as bioactive materials through their capacity to induce hard tissue formation both in the dental pulp and bone. Sealing the apex implies that the root canal filling materials interact with the periapical tissues. This work was designed to study the interactions of newly developed tricalcium silicate cement (BioRoot RCS; Septodont, Saint Maur Des Fosses, France) with apical tissue compared with a standard zinc oxide–eugenol sealer (Pulp Canal Sealer [PCS]; SybronEndo, Orange, CA).

Changes of Root Length and Root-to-Crown Ratio after Apical Surgery: An Analysis by Using Cone-beam Computed Tomography
Apical surgery is an important treatment option for teeth with post-treatment periodontitis. Although apical surgery involves root-end resection, no morphometric data are yet available about root-end resection and its impact on the root-to-crown ratio (RCR).

Selective Root Retreatment: A Novel Approach
Root canal retreatment is traditionally considered an “all or none” treatment approach. It is typically recommended that all restorative and obturation materials be removed from all roots regardless of the presence or absence of periapical pathosis. In contrast, surgical endodontics is not viewed as an “all or none” treatment approach. Traditionally, only the diseased root(s) is addressed via root-end resection and root-end filling. The use of cone-beam computed tomographic imaging allows for a more accurate evaluation of the periapical status of individual roots associated with multirooted teeth.
