Synthesis of Carbon Nitride Polymorphs by Sacrificial Template Method: Correlation between Physicochemical Properties and Photocatalytic Performance.

Carbon nitride compounds (CNCs) in the form of graphitic carbon nitride (g-CN) and poly(heptazine imide) were synthesized using different metal chloride salts (MCl), i. e., NaCl, KCl and CaCl, as sacrificial templates and by varying the MCl to melamine molar ratios.

Changes in implant stability using different site preparation techniques: Osseodensification drills versus piezoelectric surgery. A multi-center prospective randomized controlled clinical trial.

Introduction: Implant stability is influenced by bone density, implant design, and site preparation characteristics. Piezoelectric implant site preparation (PISP) has been demonstrated to improve secondary stability compared with conventional drilling techniques. Osseodensification drills (OD) have been recently introduced to enhance both bone density and implant secondary stability.

Healing of Alveolar Sockets Treated with Concentrated Growth Factors: A Split-Mouth Study.

Background: tooth extraction is a common procedure in oral surgery. The socket healing process involves hard and soft tissues and is characterized by intense remodeling, which may determine consistent dimension changes. Several autologous platelet concentrates (APCs) proved to be effective for enhancing alveolar socket healing after tooth extraction, accelerating socket closure and countering alveolar bone resorption.

Dental Implants with a Calcium Ions-Modified Surface and Platelet Concentrates for the Rehabilitation of Medically Compromised Patients: A Retrospective Study with 5-Year Follow-Up.

Background: Platelet concentrates are biological, autologous products obtained from the patient's whole blood, consisting of a supraphysiological concentration of platelets and growth factors, that have proved beneficial in different applications in the medical and dental fields. They are used in several medical and dental applications to enhance tissue healing. Previous evidence shows that platelet concentrates may be beneficial in patients with compromised systemic conditions, in which the healing process is impaired.
