Unlabelled: This systematic review aimed to verify whether there is evidence of an association between apical periodontitis and the presence of systemic biomarkers. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA. For this, the acronym PECO was used; population (P) of adult humans exposed (E) to the presence of apical periodontitis, compared (C) to adult humans without apical periodontitis, and the outcome (O) of the presence of biomarkers was observed. The articles were searched in PubMed, Scopus, Web of Science, LILACS, Cochrane Library, OpenGray, and Google Scholar grey databases. Subsequently, studies were excluded based on title, abstract, and full article reading, following the eligibility criteria. The methodological quality of the selected studies was evaluated using the Newcastle-Ottawa qualifier. After exclusion, 656 studies were identified, resulting in 17 final articles that were divided into case-control, cross-sectional, and cohort studies. Eight studies were considered to have a low risk of bias, one had a medium risk of bias, and eight had a high risk of bias. In addition, 12 articles evaluated biomarkers in blood plasma, four evaluated them in saliva, and only one evaluated them in gingival crevicular fluid. The results of these studies indicated an association between apical periodontitis and the systemic presence of biomarkers. These markers are mainly related to inflammation, such as interleukins IL-1, IL-2, and IL-6, oxidative markers, such as nitric oxide and superoxide anions, and immunoglobulins IgG and IgM.

Dental mesenchymal stem cells (MSCs) play an essential role in the development of immature permanent teeth. Bacterial infection of the pulp and periapical tissues of immature permanent teeth, the associated oral pathogens, and their virulence factors affect the viability, proliferation, differentiation, and cytokine secretion of MSCs. Bacteria and virulence factors can also trigger an inflammatory response that induces pro-inflammatory cytokine secretion and destroys odontogenic MSCs in the pulp and periapical region, negatively affecting the development of immature permanent teeth.

Background: Chronic apical periodontitis (CAP) is a prevalent oral inflammatory disease, yet the complex mechanisms underlying its etiology remain unclear. A recently identified cell death pathway known as cuproptosis may be linked to this condition.
Methods: Differentially expressed cuproptosis-related genes (DE-CRGs) were identified by integrating human CAP dataset (GSE237398) with health control (HC) dataset (GSE223924) from the Gene Expression Omnibus (GEO) database.

Introduction: Although several elegant studies have reported apical periodontitis prevalence in different populations, far less is known about its associated bone loss and its correlation to sex and age. Thus, this study investigated the impact of sex and age differences on the severity of apical periodontitis (AP) using cone-beam computed tomography (CBCT) and a volumetric periapical index (CBCT-PAI).
Material And Methods: CBCT scans of 401 patients (1,027 teeth) were analyzed by calibrated examiners in CBCTPAI.

Introduction And Aims: Calcified root canals in mandibular anterior teeth present significant therapeutic challenges due to their narrow anatomy and minimal tolerance for procedural errors. This case report demonstrates the successful integration of robot-assisted navigation with an ultra-fine bur to address these challenges.
Methods: A 44-year-old male presented with symptomatic chronic apical periodontitis and pulp calcification in a mandibular lateral incisor, 20 years after orthodontic treatment.

The most important stage in the surgical treatment of chronic apical periodontitis is the creation of a sealed barrier that prevents the penetration of microorganisms outside the root canal. The choice of the most optimal material for retrograde sealing is a process that requires special attention. Many different types of sealing materials used in apical surgery are presented.
