Damage of pulp tissue usually begins in the coronal pulp. Its mistreatment or its lack of on time detection determines the progressive inclusion of the whole endodontic space in its evolution, opening the way of its expansion in the surrounding tissues of the tooth, and on the marginal apical tissue. The goal of this study was to highlight that the primary endodontic lesions with secondary periodontal implication healed and bone repair was obtained due to a proper disinfection and an adequate sealing of the endodontic system. In primary endodontic lesion with secondary periodontal involvement, endodontic treatment is required in the first stage followed by specific periodontal treatment. The prognosis is good if an appropriate endodontic approach is chosen, depending on the stage of the periodontal disease and the treatment response. The identification of the etiological factors is the most important to establish the appropriate treatment. In all clinical cases selected in this article, the healing tendency was noticed after an adequate disinfection and sealing of the endodontic system.

Statement Of The Problem: Success of pulpotomy of primary teeth depends on biological and cytotoxic effects of pulp capping agents. Mineral trioxide aggregate (MTA), Biodentine, calcium enriched mixture (CEM) cement, and ferric sulfate (FS) are among the commonly used pulp capping agents (PCAs) for pulpotomy, and their successful application has been previously evaluated.
Purpose: This study aimed to compare the cytotoxicity of PCAs against mesenchymal stem cells isolated from human exfoliated deciduous teeth (SHEDs).
Background And Objectives: Although effective irrigation methods are crucial for pulpectomy in primary teeth (PT), no consensus exists on the best technique. This study guides clinicians in making evidence-based choices for irrigation techniques in PT.
Design: This study reviewed in vitro and in vivo research on PT using an extensive electronic search up to April 2024.
Objective: This study aims to evaluate the efficacy of photodynamic therapy as an adjunct to conventional endodontic treatment in patients with apical periodontitis and fistulas. In this study, a fistula is characterized as a pathological conduit originating from the infected region at the root apex of the tooth, traversing the oral mucosa, and extending to the external surface of the gingiva. This pathological condition frequently complicates the management of endodontic infections, thereby necessitating the evaluation of supplementary therapeutic interventions.
This study assessed the impact of pre-enlarging the root canal using a size 25 K-file on the fracture incidence of three reciprocating instruments after multiple uses. After a glide path performed with a size 15 K-file, the instruments (Reciproc R25, Reciproc Blue R25, and WaveOne Gold Primary) were initially used in 936 root canals. Then, for the second and third uses (933 and 927, respectively), a pre-enlargement using a size 25 K-file at the working length was done.
Enterococcus faecalis is a common cause of nosocomial infections and is frequently associated with endodontic infections. However, there is a scarcity of studies addressing the genetic characterization of E. faecalis lineages most commonly associated with root canals.
