Summary: The quality of root canal filling has an impact on the status of periapical lesions. The absence of gaps in the filling and an apical filling extension of 0-2mm below the apex can reduce the occurrence of unhealed periapical lesions.

Summary: The study demonstrates that the outcome of endodontic treatment is dependent on the severity of periapical changes. Complications and retreatment cases with periapical lesions are associated with negative treatment outcomes. PESS is an effective tool for predicting outcomes of teeth with low to moderate treatment risk of AP.

Summary: This case report presents a novel guided endodontics technique using a sleeveless 3-dimensional-printed guide, which allows for a minimally invasive access cavity up to the root canal. The technique shows promise as an alternative to conventional guided endodontics in cases where vertical space is limited, for negotiating pulp canal obliteration.

Summary: This study retrospectively evaluated the extent and speed of bone healing of large periapical lesions associated with non-surgical root canal treatment or retreatment. The results showed that older patients and larger initial lesion volume were associated with a significantly longer healing time. However, gender, filling material, and treatment type did not have a significant effect on the healing process. CBCT monitoring is critical for the diagnosis and treatment decision-making process of large periapical lesions.

Summary: Teeth adjacent to both implant- and natural tooth-supported crowns showed a higher prevalence of root canal treatment and coronal restorations compared to nonadjacent teeth. The odds of having root canal treatment were 2.57 times higher when adjacent to an implant-supported crown and 4.39 times higher when adjacent to a tooth-supported crown. Similarly, the odds of needing a restorative procedure were 1.63 and 2.30 times higher, respectively, in these cases.

Summary: This prospective study investigated the 4-year outcome and prognostic factors of nonsurgical root canal retreatment by measuring the volumetric change of periapical radiolucencies on CBCT scans. The study found a significant reduction in periapical radiolucencies at 4 years postoperatively, with tooth type identified as a predictor of outcome. Overall, the retreatment of endodontically treated teeth showed predictable and successful results.

Summary: The aim of this study was to investigate the levels of molecular markers of inflammation in patients undergoing non-surgical root canal retreatment and periapical surgery for apical periodontitis, and to determine if these levels are influenced by the size of apical radiolucencies and treatment outcome. The results showed that both symptomatic and asymptomatic apical periodontitis could contribute to increased levels of inflammatory markers. Treatment resulted in transient increases in inflammatory markers, but successful treatment and surgery led to long-term reduction in these levels.

Summary: The study evaluated the prevalence of missed canals in endodontically treated maxillary molars through CBCT images and found that MB2 was the most frequently missed canal, associated with the presence of periapical lesions.

Summary: This study investigated the antibacterial effect of root canal sealer containing DMADDM on persistent apical periodontitis in beagle dogs. The results showed that DMADDM-modified sealer significantly reduced the volume of periapical lesion and inflammatory grade, especially in cases of E. faecalis-induced reinfection.

Summary: The study found that bacteria, especially Porphyromonas spp., were frequently detected in endodontic canals and apical lesions. Total bacteria and Porphyromonas endodontalis DNA were also found in peripheral blood mononuclear cells, indicating their potential role in bacterial systemic translocation.

Summary: Persistent apical periodontitis is a critical challenge in root canal therapy. Developing root canal filling materials with continuous antibacterial effects and tight seal is important to prevent treatment failure and persistent apical periodontitis. In this study, we modified the EndoREZ root canal sealer by adding the antibacterial material DMADDM and magnetic nanoparticles (MNPs). The modified sealer showed good mechanical properties, biocompatibility, and enhanced antibacterial effects on multispecies biofilms under a magnetic field. In vivo study demonstrated its inhibitory effect on persistent apical periodontitis with minimal resorption and slight increase in periodontal ligament space.

Summary: This study aimed to compare the radiographically assessed periapical changes of endodontically treated teeth over 2 years of follow-up and to analyze disagreements in periapical lesion size estimates around the same roots using DPR and CBCT.

Summary: This study analyzed the morphological changes of root apex in anterior teeth with periapical periodontitis. The results showed that anterior teeth with periapical periodontitis had shorter distances between apical constriction and anatomical apex, larger disparities between the diameters of buccolingual and mesiodistal, and a higher proportion of flaring apical constriction.

Summary: The study investigated the impact of root canal curvature angle on maintaining the real working length using a reciprocating rotary instrumentation technique. The results showed no significant relation between the degree of canal curvature angle and the accuracy of radiographic working length estimation. Post-instrumentation changes in the original canal axis were also found to be statistically non-significant between moderate and severe canal curvature angles.

Summary: The study evaluated the salivary detection of XRCC1 rs25487 SNP in Colombian population and its relationship with clinicopathological characteristics in oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma (OSCC). While no independent association with OPMD/OSCC risk was found, significant interaction effects were observed between the SNP and demographic/behavioral variables, indicating a potential role in the etiopathogenesis of these diseases.

Summary: This study aimed to identify objective clinical and ultrasonographic parameters for the selection of candidates for buccal fat pad (BFP) removal. The results showed that cheek skin-fold thickness, midfacial contour, ultrasonographic BFP volume, and facial form could be robust indicators for the suitability for the procedure. It is recommended to consider a combination of at least three of these criteria for surgical decision-making.

Summary: This report describes the usefulness of a computer-assisted dynamic navigation system for root canal treatment, which is important for teeth with pulp canal obliteration and crown discoloration due to traumatic injury. The system allows accurate localization of the root canal and conservative treatment, resulting in good restoration of the teeth and intact periapical structures.
