Stem Cell-Based Therapies In Periodontology And Implant Dentistry: A Systematic Review And Meta-Analysis, Abdullah Saeed, Marycris Padrigo

International Arab Journal of Dentistry

Introduction: Periodontal disease and peri-implantitis remain the leading causes of tooth and implant loss, and conventional regenerative procedures consistently fall short of full structural restoration. Stem cell therapies have emerged as a promising alternative, operating through multi-lineage differentiation, immunomodulation via paracrine signaling, and extracellular vesicle communication. Prior systematic reviews, however, lacked methodological rigor — omitting clustering adjustments, REML/HKSJ estimation, prediction intervals, and publication bias modeling.

Aim: This systematic review and meta-analysis evaluated whether stem cell therapy produces superior clinical and radiographic outcomes compared to cell-free controls in adults with periodontal or peri-implant bone defects.

Methods: Searches across …

Delivering Sustainability: Improving Medical Waste Segregation Through Staff Education On Labor & Delivery, Haley Primuth, Kari Schmidt Oliver, Manuel R. Lamptey, Anne Getzin, Deborah Simpson

Aurora GME

Introduction

Climate change has known impacts on the health of the maternal-fetal dyad. Economic instability, flooding and displacement lead to reduced access to care, disrupted crop yields and food supply challenges. Extreme heat has been linked to increased rates of fetal growth restriction, preterm delivery and stillbirth. Healthcare makes up 4.4% of net global emissions and work on Labor and Delivery (L&D) generates significant waste. Even when incineration of regulated medical waste (“red bag waste”) is done properly, there are still emissions which include greenhouse gases, heavy metals, toxins and particulate matter. It is estimated that 3-10% of total waste …
