Article Synopsis
  • Endodontic infections include issues like pulp necrosis and abscesses, where identifying harmful bacteria like Enterococcus faecalis and others is crucial for proper diagnosis and treatment.
  • A systematic review analyzed the prevalence of these bacteria using the Checkerboard DNA-DNA hybridization technique across 17 studies, evaluating 620 samples, finding high prevalence rates (74% for E. faecalis, 63% for P. gingivalis, etc.).
  • The presence of these bacteria can hamper endodontic therapy effectiveness and is often linked to recurring infections, making DNA-DNA hybridization a valuable and efficient tool for tailored endodontic treatments.

Article Synopsis
  • Oral leiomyomatous hamartoma (OLH) is a benign overgrowth of smooth muscle tissue that can occur in various locations in the oral cavity.
  • The systematic review analyzed 55 studies involving 66 subjects, revealing that OLH lesions typically presented firm consistency, average size of 1.20 cm, and were often found on the tongue or maxilla, with surgical excision being the primary treatment method.
  • Despite its rarity, OLH is important for differential diagnosis in young patients with oral lesions, given its distinct clinicopathological features identified in the reviewed literature.

Meta-learning of dental X-rays is a machine learning technique that can be used to train models to perform new tasks quickly and with minimal input. Instead of just memorizing a task, this is accomplished through teaching a model how to learn. Algorithms for meta-learning are typically trained on a collection of training problems, each of which has a limited number of labelled instances.

Background: Activation of the IL-33/ST2 axis leads to the production of proinflammatory cytokines and thus to the triggering of osteoclastogenesis, which is why it plays an important role in the immunopathogenesis of periodontitis. The aim of this study was to compare IL-33 levels in serum, plasma, saliva and gingival crevicular fluid (GCF) of subjects with chronic periodontitis (CP) in comparison with the control group (CG).

Methods: This systematic review and meta-analysis followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and was registered in the Open Science Framework (OSF): https://doi.

Background: Fixed dental prostheses (FDP) can affect the production of inflammatory cytokines causing damage to periodontal tissues. A systematic review and meta-analysis was carried out with the following two objectives: (1) to determine the prevalence and function of the different inflammatory cytokines present in gingival crevicular fluid (GCF) of teeth with metal-ceramic (M/C) and all-ceramic (A-Cs) prostheses, and (2) to analyze and compare the levels of inflammatory cytokines in GCF of teeth with M/C and A-Cs prostheses.

Methods: The protocol followed PRISMA and Cochrane guidelines and was registered in the OSF:10.

Background: Podoplanin (PDPN) is a transmembrane glycoprotein implicated in the pathogenesis of odontogenic lesions (OL). It is localized at the membrane and cytoplasmic level, and its interaction with other proteins could trigger cell proliferation, invasion and migration. The main objective of this systematic review is to explore the immunoexpression pattern of podoplanin in OL.

Article Synopsis
  • A polymicrobial dysbiotic film triggers an immune response in periodontal tissues, leading to increased IL-18 production, which then heightens inflammatory cytokines, worsening chronic periodontitis.
  • A systematic review and meta-analysis following PRISMA guidelines examined IL-18 expression across various biological samples from individuals with chronic periodontitis, analyzing data from multiple databases.
  • The results showed significantly higher IL-18 levels in the serum, saliva, and gingival crevicular fluid (GCF) of chronic periodontitis patients compared to healthy individuals, suggesting the potential of IL-18 as a valuable diagnostic marker.

Implant-supported complete dentures are a common procedure for patients with mandibular edentulism problems. This article documents the protocol for immediate functional loading of fixed transient mandibular prostheses with fully moldable attachments and distal extensions to prevent fractures. A 56-year-old female patient was referred to the Oral Rehabilitation and Implantology Service due to periodontal problems, difficulty in chewing capacity and aesthetic compromise.

Background: DNA is an important target for oxidative attack and its modification may increase the risk of mutagenesis. The aim of this study was to evaluate and compare salivary levels of the oxidative stress biomarker 8-hydroxy-2'-deoxyguanosine (8-OHdG) in patients with oral cancer (OC) compared to the control group by a comprehensive search of the available literature.

Methods: The present systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and was registered in Open Science Framework (OSF): https://doi.

Background: Cytokines play an important role in the immunopathogenesis of dental caries. A systematic review and meta-analysis was carried out with the following three objectives: 1)To deepen and discuss through a comprehensive analysis of the literature the effects of dental caries on the activity and levels of TNF-α, IL-6 and IL-8 in saliva of children and young adults, 2)To compare the levels of this cytokines in saliva of the exposure group (moderate-severe dental caries) with the control group (caries-free or mild dental caries), and 3)To determine whether the levels of these cytokines could be used as a complementary clinical diagnostic tool to assess the severity of dental caries.

Methods: The protocol followed PRISMA and Cochrane guidelines and was registered in the Open Science Framework (OSF): https://doi.

Objective: To describe the existing knowledge about metal-free prosthetic biomaterials according to their physicochemical properties and based on this, define criteria for their placement in both the anterior and posterior sectors.

Materials And Methods: A digital search was carried out in the databases: PubMed/Medline, Scopus, Web of Science and Google Scholar of the literature published in the English language without time restrictions and included original articles such as case reports, retrospective and prospective studies, narrative, comprehensive, systematic reviews and meta-analysis. Meanwhile, short communications, editorials and articles in a language other than English were excluded.

Prosthetic biomaterials can affect the composition of the subgingival microbiota and consequently the production of proinflammatory cytokines, causing damage to the periodontium. A total of 40 patients were divided into two groups: 20 with monolithic zirconia (MZ) prostheses and 20 with porcelain fused to metal (PFM) with nickel-chromium (Ni-Cr) alloy prostheses. Subgingival plaque and gingival crevicular fluid samples were taken.

Objective: This systematic review aimed to investigate the role of the C-X3-C motif ligand 1/chemokine receptor 1 C-X3-C motif (CX3CL1/CX3CR1) axis in the pathogenesis of periodontitis. Furthermore, as a secondary objective, we determine whether the CX3CL1/CX3CR1 axis could be considered complementary to clinical parameters to distinguish between periodontitis and rheumatoid arthritis (RA) and/or systemically healthy subjects.

Methods: The protocol used for this review was registered in OSF (10.

Background: Ameloblastoma (AM), the benign counterpart of ameloblastic carcinoma, is a benign odontogenic tumor of epithelial origin, naturally aggressive, with unlimited growth potential and a high tendency to relapse if not adequately removed. Patients with AM treated surgically can benefit from dental implant therapy, promoting oral rehabilitation and improving their quality of life. The present study aimed to determine the survival rate of dental implants placed after surgical treatment of patients affected by AM.
