For decades the dismantling of previous dental work to correct inferior root canal procedures or to address recurrent dental caries has provided a significant amount of work for the restorative dentist. When coupled with teeth that have been root treated and also have an intraradicular post or dowel, the clinician was often presented with the challenge of post removal, without fracturing the root, and revision (retreatment) of the root canal procedures. While today's contemporary dentistry has the wherewithal to use ultrasonic devices to loosen and remove the post, this was not always the case historically, and creativity in this process was the hallmark of many of our predecessors.

Objective: This study investigated the associations among endodontic instruments, ultrasonic tips and various final irrigation protocols for removing intracanal and intratubular biofilms in long oval canals.
Methodology: One hundred mandibular premolars inoculated with Enterococcus faecalis were divided into two groups: the control group (CG: n = 10), which received no treatment; and the test groups (n = 30), which included saline (SS), sodium hypochlorite (2.5% NaOCl) and chlorhexidine (2% CHX).
Biomechanical Behaviors of Molars Restored with Endocrowns Composed of Different Materials.

Department of Cariology and Endodontology, Peking University School and Hospital of Stomatology, Beijing 100101, China.
To assess the biomechanical behaviors of endodontically treated molars (ETMs) restored with endocrowns composed of different materials, forty mandibular molars were assigned to five groups (n = 8 each). Untreated molars constituted the control group (group C); the rest of the teeth that underwent root canal therapy were restored with endocrowns composed of polycrystalline ceramics (ST zirconia, UPCERA) in group ZR, lithium disilicate glass ceramics (UP.CAD, UPCERA) in group LD, resin-based nanoceramics (Hyramic, UPCERA) in group NC, and feldspathic ceramics (CEREC Blocs, Sirona) in group FC.

January 2025
Faculty of Dentistry, University of Santiago de Compostela, 15782 Galicia, Spain.
: This systematic review aimed to compare the effect of chitosan in smear layer removal with other commonly used chelators during root canal treatment. : The PRISMA guidelines were followed. Ex vivo studies performed in non-endodontically treated extracted human permanent teeth with a fully formed apex, in which sodium hypochlorite was the main irrigant and chitosan was used as final irrigation to observe its capacity to remove the smear layer using a Scanning Electron Microscope (SEM), were included.

BMC Oral Health
January 2025
Department of Agr. Machinery and Technology Engineering, Akdeniz University, Antalya, Turkey.
Background: Examining stress distributions in abutment teeth with periapical lesions is essential for understanding their biomechanical impact on dental structures and tissues. This study uses finite element analysis (FEA) to evaluate these stress patterns under occlusal forces, aiming to enhance treatment strategies and prosthetic designs.
Methods: Three FEA models were created: a healthy mandibular premolar (Model 1), a premolar with a single crown and a lesion repaired using a fiber-post (Model 2), and 3) a premolar with a lesion repaired using fiber-post to support a four-member bridge (Model 3).
