The Impact of Membrane Stabilization for Alveolar Ridge Preservation in Periodontally Compromised Extraction Sockets: A Non-Inferiority Randomized Controlled Trial.
J Clin Periodontol
December 2024
Department of Periodontology and Dental Research Institute, School of Dentistry, Seoul National University, Seoul, Republic of Korea.
Aim: The aim of this study was to investigate the non-inferiority of alveolar ridge preservation (ARP) with membrane stabilization compared with non-stabilization, focusing on changes of soft-tissue contour in periodontally compromised extraction sockets. Secondary outcomes included changes in hard-tissue contour, patient-reported outcomes and new bone formation.
Materials And Methods: Twenty-four patients with periodontally compromised teeth were randomly assigned to ARP with (test group) or without (control group) membrane stabilization.
Effect of Er,Cr:YSGG Laser Irradiation on the Surface Modification and Cell Adhesion on Titanium Discs: An In Vitro Study.
Materials (Basel)
October 2024
Division of Periodontology, Department of Oral Medicine, Infection and Immunity, Harvard School of Dental Medicine, Boston, MA 02115, USA.
This study evaluates the potential of erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser irradiation to modify the titanium surface for optimal seeding of fibroblasts and osteoblasts in the treatment of peri-implantitis. Titanium discs were treated using the Er,Cr:YSGG laser, an ultrasonic device with a stainless tip, or titanium scalers. Changes in surface properties were analyzed by profilometer and scanning electron microscopy (SEM).

Objectives: This study aimed to assess the surface roughness, surface free energy (SFE), and shear bond strength (SBS) on a lithium disilicate glass-ceramic surface following varying etching protocols (time variation) and application of silane either with or without adhesive material.
Methods And Materials: Lithium disilicate glassceramic (LDGC) computer-aided design and computer-aided manufacture (CAD/CAM) blocks were cut using a slow-speed cutting mechanism. CAD/CAM blocks were then evaluated for surface roughness, 6 groups (n=20); SFE,12 groups (n=5); and SBS, 10 groups (n=10).
Investigating Flow-Induced Corrosion of Magnesium in Ophthalmological Milieu.
Materials (Basel)
September 2024
Chemistry Materials and Chemical Engineering Department "Giulio Natta", Politecnico di Milano, 20133 Milan, Italy.
Although the impact of local fluid dynamics in the biodegradation of magnesium is well known, currently no studies in the literature address the degradation effects of ocular vitreous on bioresorbable devices made of magnesium, which could be developed as drug delivery carriers. The aim of this study was to investigate the flow-induced corrosion mechanism of magnesium in an ophthalmological environment for future applications in ophthalmic drug delivery. To achieve this, experimental and computational methods were combined.

Clinic of Reconstructive Dentistry, Center of Dental Medicine, University of Zurich, Zurich, Switzerland.
Aim: A new, non-invasive approach suggests using single intraoral optical scanning to analyze the ridge profile of single-tooth gaps following alveolar ridge preservation in the absence of a baseline scan. This method involves creating a three-dimensional (3D) surface map to identify and assess contour changes and ridge profiles based on the adjacent teeth.
Materials And Methods: The present study was designed as a cross-sectional pilot analysis on a convenience sample of patients undergoing alveolar ridge preservation.
