[Einfluss von Gender auf Parodontitis: Prävention, Prävalenz und Ätiologie in einer narrativen Übersicht].

Periodontitis leads to a destruction of the tooth-supporting apparatus, which untreated may end up in tooth-loss. Key factor in the pathogenesis of periodontitis is the host immune response, genetic predisposition, and lifestyle factors (such as smoking, stress, and diabetes), all of which influence disease severity. Periodontitis is more common in men than women, this fact may point out that gender may have an influence on periodontitis.

Weighing up the potential of "superfoods" compounds of green tea or turmeric as adjuncts in comparison to established therapeutical approaches for periodontal disease.

Objective: Aim of this study was to critically appraise clinical evidence on the potential benefits of adjunctive use of superfoods green tea and turmeric as mouthrinse or local delivery agents in the treatment of periodontal disease.

Materials And Methods: Electronic searches were performed in four databases for randomized trials from inception to February 2024 assessing the supplemental use of superfoods green tea and turmeric for gingivitis/periodontitis treatment. After duplicate study selection, data extraction, and risk-of-bias assessment with the RoB 2 tool, random-effects meta-analyses of Mean Differences (MD) or Standardized Mean Differences (SMD) with their 95% confidence intervals (CI) were performed.

Aims: This preclinical study aimed to evaluate the periodontal tissue regenerative capacities of poly (lactic acid/caprolactone) (PLCL) bilayer membrane in one-wall intrabony defects in dogs. No study has assessed the efficacy of PLCL bilayer membrane for periodontal regeneration therapy despite the fact that PLCL bilayer membrane has proved efficient for bone regeneration.

Methods: In five beagle dogs, the bilateral mandibular second and fourth premolars were extracted 8 weeks before the experimental surgery.

Effects of i-PRF, A-PRF+, and EMD on Osteogenic Potential of Osteoblasts on Titanium.

Objective: The study evaluates three biologically active substances with known bone-inductive potential on previously decontaminated titanium (Ti) discs.

Material And Methods: Rough and smooth Ti surfaces were contaminated with a multispecies biofilm and cleaned with a chitosan brush. Discs were treated either with injectable-platelet-rich fibrin (i-PRF), advanced platelet-rich fibrin (A-PRF+), or enamel matrix derivatives (EMDs) before osteoblast seeding.

Comparison of clinical parameters of peri-implantitis and parameters related to tissue macrophage sensitization on TiO.

Objective: Dental implants show impressive survival and like rates, but peri-implantitis is a frequent inflammatory disease which affects the implant-surrounding tissues. While biofilms on the implant surface is considered its etiologic reason, several risk factors determine the pace of progression of peri-implant bone loss. Some risk factors are generally accepted while others are still unconfirmed and a matter of ongoing discussion.

[Tooth preservation and "the treatable or hopeless tooth": Re-thinking a concept].

The masticatory organ is at the center of dental practice. Tooth loss, regarded as an organ failure, is a core dispute in our profession, as it more often than not does not happen spon-taneously but is influenced by the dentist's treatment plan. Despite the prosthetic possibili-ties of tooth replacement, efforts should be made to preserve as many teeth as possible.

Injectable Platelet-Rich Fibrin and Advanced Platelet-Rich Fibrin Demonstrate Enhanced Anti-Biofilm Effect Compared to Enamel Matrix Derivatives on Decontaminated Titanium Surfaces.

Background: The search for effective antimicrobial agents to mitigate peri-implant infections remains a crucial aspect of implant dentistry. This study aimed to evaluate and compare the antimicrobial efficacy of i-PRF, A-PRF+, and enamel matrix derivative (EMD) on decontaminated rough and smooth titanium (Ti) discs.

Materials And Methods: Rough and smooth Ti discs were coated with multispecies biofilm and thoroughly debrided using a chitosan-bristled brush.

In vitro and in vivo investigation of antibacterial silver nanoparticles functionalized bone grafting substitutes.

Infection is a major concern in surgery involving grafting and should be considered thoroughly when designing biomaterials. There is considerable renewed interest in silver nanoparticles (AgNPs) owing to their ability to potentiate antibacterial properties against multiple bacterial strains. This study aimed to develop two antibacterial bone regenerative scaffolds by integrating AgNPs in bovine bone particles (BBX) (Product 1), and a light cross-linked hydrogel GelMA (Product 2).

A proof of concept on implant-supported bilateral cantilever bridges: The T-Bridge approach.

The concept of bilateral cantilevers on a single central implant (T-design) for three-unit implant-supported fixed dental prostheses (ISFDPs) has not been explored nor tested. This technical hypothesis aimed to explore the feasibility of such an approach as a cost-effective alternative to conventional treatments. Careful considerations regarding implant diameter, length, ideal position, occlusal scheme, and bone remodeling are essential to ensure adequate support, stability, and prevention of complications.

[Autologous platelet concentrates in regenerative dentistry - A narrative literature review. Part II: clinical application of PRF in periodontology and implantology].

The clinical impact of platelet-rich fibrin (PRF) and plasma rich in growth factors (PRGF®) respectively has been studied extensively in the field of regenerative dentistry during the last two decades. Literature supports evidence for additional benefits in regenerative periodontal therapy, alveolar ridge preservation, management of extraction sockets, implantology including guided bone regeneration as well as defect management in oral surgery. Regarding gingival wound healing and soft tissue regeneration, there is sufficient evidence for their positive effects which have been confirmed in several systematic reviews.

[Autologous platelet concentrates in regenerative dentistry - A narrative literature review. Part I: Theoretical and legal aspects of the PR(G)F application].

The use of autologous platelet concentrates (APC) such as platelet-rich fibrin (PRF) and/or plasma rich in growth factors (PRGF®) is considered an established treatment modality in re-generative dentistry. The possibility of delivering growth factors over aclinically relevant time of several days seems particularly interesting in the context of wound healing.The growing body of evidence in the field of APC requires a continuous and actual knowledge of the literature for being able to make evidence-based treatment recommendations with a realistic assessment of possible advantages of this technology.

In vivo healing of low temperature deproteinized bovine bone xenograft in a rabbit cranial model.

The physicochemical properties of grafting materials affect the quality of the osteointegration, resorption rate, and the new bone (NB) formation. This study assessed the physicochemical properties and integration of a low temperature deproteinized bovine bone xenograft (BBX), referred to as optimized MoaBone® (OMB). This novel BBX was physiochemically characterized both pre and post chemical bleaching and sterilization by gamma irradiation.
