Adult maxillary expansion: CBCT evaluation of skeletal changes and determining an efficiency factor between force-controlled polycyclic slow activation and continuous rapid activation for mini-screw-assisted palatal expansion - MASPE vs. MARPE.

Aim: This consecutive retrospective study compared Mini-implant Assisted Slow Palatal Expansion (MASPE) with rapid palatal expansion (MARPE) using a bone-borne skeletal expander in adults with a narrow maxilla. CBCT scans analyzed transverse changes and potential pterygoid process deformation before (T1) and after expansion (T2).

Materials And Methods: The Force Controlled PolyCyclic (FCPC) SLOW palatal expansion group (FCPC-MASPE-G) comprised 35 adults aged 18-54 years and received a skeletal expander limiting expansive force only allowing 500 cN at the activation wrench (force control).

The Relationship between Nocturnal Enuresis and Obstructive Sleep Apnea in Children.

Background: The aim of this study is to determine the prevalence of nocturnal enuresis (NE) in children with obstructive sleep apnea (OSA), the effect of adenotonsillectomy (AT) and the width of the arches, and to compare them with control children without respiratory problems.

Methods: Children from 2 to 12 years old were divided into three groups: children with OSA and NE (n = 51), children with OSA without NE (n = 79), and the control group (n = 168). NE was defined as at least one bedwetting incident per month.

Efficient Hydroxyapatite Extraction from Salmon Bone Waste: An Improved Lab-Scaled Physico-Chemico-Biological Process.

The demand for novel tissue grafting and regenerative wound care biomaterials is growing as traditional options often fall short in biocompatibility, functional integration with human tissue, associated cost(s), and sustainability. Salmon aquaculture generates significant volumes of waste, offering a sustainable opportunity for biomaterial production, particularly in osteo-conduction/-induction, and de novo clinical/surgical bone regeneration. Henceforth, this study explores re-purposing salmon waste through a standardized pre-treatment process that minimizes the biological content, followed by a treatment stage to remove proteins, lipids, and other compounds, resulting in a mineral-rich substrate.

A novel Chilean salmon fish backbone-based nanoHydroxyApatite functional biomaterial for potential use in bone tissue engineering.

Introduction: Given the ensuing increase in bone and periodontal diseases and defects, bone repair and/or regeneration strategies are constantly undergoing-development alongside advances in orthopedic, oro-dental and cranio-maxillo-facial technologies and improvements in bio-/nano-materials. Indeed, there is a remarkably growing need for new oro-dental functional biomaterials that can help recreate soft and hard tissues and restore function and aesthetics of teeth/ dentition and surrounding tissues. In bone tissue engineering, HydroxyApatite minerals (HAp), the most stable / bioceramic and a widely-used material as a bone graft substitute, have been extensively studied for regenerative medicine and dentistry applications, including clinical use.
