Article Synopsis
- - This study examines the differences and advantages in healthcare information provided by AI chatbots regarding adjuvant therapy for endometrial cancer across four regions: Indonesia, Nigeria, Taiwan, and the USA, and through three platforms: Bard, Bing, and ChatGPT-3.5.
- - An analysis of chatbot responses revealed significant regional variations in quality, with Bing performing the best in Nigeria and Bard showing superior results compared to ChatGPT-3.5 across all areas assessed.
- - The findings underscore the need for further research and development to ensure equitable access to reliable AI-generated medical information, as the quality of information varies widely depending on location and the platform used.
Purpose: Peri-implantitis therapy and implant maintenance are fundamental practices to enhance the longevity of zirconia implants. However, the use of physical decontamination methods, including hand instruments, polishing devices, ultrasonic scalers, and laser systems, might damage the implant surfaces. The aim of this systematic review was to evaluate the effects of physical decontamination methods on zirconia implant surfaces.

Background: Physical decontamination methods commonly used in peri-implantitis therapy and routine implant maintenance can potentially alter zirconia implant surfaces.
Methods: Acid-etched zirconia discs were instrumented with titanium curette (TC), plastic curette, air abrasive device, ultrasonic scaler (US) with stainless steel tip.
