The impact of hyaluronic acid coating on polyether ether ketone dental implant surface: An in vitro analysis.

Objective: Polyether ether ketone (PEEK), a biocompatible polymer, is being explored as an alternative to metallic alloys for dental implants due to its aesthetic and mechanical properties. This study aimed to enhance the surface biofunctionality through evaluating human MG-63 osteoblastic cell survival, proliferation, differentiation, and mineralization.

Method: Following the sandblasting and plasma treatment of the 3D-printed PEEK discs, a layer of hyaluronic acid (Hya) was coated onto the PEEK surface.

Impact of the halitosis on QoL in overweight and obese patients: Based on six years of experience in two centers in sulaimani governorate, Kurdistan Region/Iraq, and case series study.

Background/objectives: The patients who are overweight and obese, are under stress of excess body weight, embarrassed, one may imagine the impact of halitosis on this group of patients, this is an attempt to evaluate this extra impact, and which aspect of quality of life will be affect in the overweight and obese.
