Background: Scaffold (SCA) functionalization with aptamers (APT) provides adsorption of specific bioactive molecules on biomaterial surfaces. The aim of this study was to observe if SCA enriched with anti-fibronectin APT can favor coagulum (PhC) and osteoblasts (OSB) differentiation.

Methods: 20 μg of APT was functionalized on SCA by simple adsorption.

Immediate loading of dental implants shortens the treatment time and makes it possible to give the patient an esthetic appearance throughout the treatment period. Placement of dental implants requires precise planning that accounts for anatomic limitations and restorative goals. Diagnosis can be made with the assistance of computerized tomographic scanning, but transfer of planning to the surgical field is limited.

Two bovine hydroxyapatites (BHAs), one with granule size of 150 to 200 microm and one with granule size of 300 to 329 micro, and 2 synthetic hydroxyapatites (SHAs), with granule size of 150 and 300 microm, respectively, were compared for effectiveness in repairing circumferential bone defects in dogs. The hydroxyapatites (HAs) were characterized through powder x-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Three trephined bone defects (5.

Background: The acellular dermal matrix graft (ADMG) has become widely used in periodontal surgeries as a substitute for the subepithelial connective tissue graft (SCTG). These grafts exhibit different healing processes due to their distinct cellular and vascular structures. Therefore the surgical technique primarily developed for the autograft may not be adequate for the allograft.

Article Synopsis
  • The study explored how non-surgical periodontal therapy impacts blood sugar levels in type 2 diabetes patients with periodontitis.
  • Thirty subjects were divided into two groups: one received full-mouth scaling and antibiotics, while the other received only scaling.
  • After three months, both groups showed improved gum health and reduced HbA1c levels, but only the group that didn’t receive antibiotics had statistically significant reductions in HbA1c.

This study compared the clinical and microbiological status of periodontally diseased sites in 42 patients who had a renal transplant and were undergoing immunosuppressive therapy (21 taking azathioprin and corticosteroids [Az-C] and 21 taking cyclosporin-A [Cy-A] with those of 21 systemically healthy matched controls. Probing pocket depth (PPD), bleeding on probing (BOP) and gingival hyperplasia (GH) were measured at 339 sites. Subgingival plaque samples were analyzed for the presence of Porphyromonas gingivalis, Treponema denticola and/or Bacteroides forsythus using the BANA test.
