Dental implant placement accuracy with robotic surgery compared to free-hand, static and dynamic computer assisted techniques: Systematic review and meta-analysis.

Background: This systematic review and meta-analysis compared the accuracy of robotic-assisted dental implant placement (r-CAIS) with conventional freehand, static computer-assisted (s-CAIS), and dynamic computer-assisted (d-CAIS) techniques.

Methods: A comprehensive search was conducted in PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library from January 2000 to January 2024. Studies meeting PICOST criteria, including clinical and in vitro studies, were included.

Facet dependent ultralow thermal conductivity of zinc oxide coated silver fabric for thermoelectric devices.

The conversion efficiency of a thermoelectric power generator depends on the dimensionless figure-of-merit (ZT) of the constituent thermoelectric materials, which is mainly determined by their Seebeck coefficient as well as the electrical and thermal conductivity. ZnO holds promise for thermoelectric applications, yet its use is currently limited by low electrical conductivity and high thermal conductivity. Herein, we demonstrate how thermal conductivity of ZnO can be significantly reduced by intelligently combining it with a cellulose-based Ag fabric using a one-step hydrothermal method, and how different ratios of zinc nitrate hexahydrate (ZNH) to hexamethylenetetramine (HMT) can be used to fine-tune the thermoelectric performance of the resulting composite.

Evaluation of validity and reliability of AI Chatbots as public sources of information on dental trauma.

Aim: This study aimed to assess the validity and reliability of AI chatbots, including Bing, ChatGPT 3.5, Google Gemini, and Claude AI, in addressing frequently asked questions (FAQs) related to dental trauma.

Methodology: A set of 30 FAQs was initially formulated by collecting responses from four AI chatbots.

Outcomes of Totally Endoscopic Versus Microscopic Techniques in Middle Ear Cholesteatoma: A Systematic Review and Meta-Analysis.

Endoscopes have revolutionized the field of otology for the past two decades due to its minimally invasive technique and improved visualization. The advantage of endoscope during surgery for middle ear cholesteatoma both for diagnosing and aiding in removal of residual disease from the hidden areas and the resulting lower recurrence rates have been proven in the past by many authors. But the feasibility of totally endoscopic ear surgery and its surgical and patient related outcomes are yet to be explored in detail.

Pyomyositis of the Piriformis Muscle-A Case of Piriformis Syndrome.

Piriformis syndrome is a rare cause of sciatica, which results in low backache due to sciatic nerve compression. This syndrome is associated with abnormalities in the piriformis muscle, which cause sciatic nerve entrapment, like anatomical variations, muscle hypertrophy, and inflammation. It can also result from the abnormal course of sciatic nerve itself through normal piriformis muscle.
