Enhancing visualization within the oral cavity has long been a goal of dental practitioners. External lighting sources, patient positioning, and the use of mirrors have been employed since the onset of modern dentistry. However, as the complexity of dental and oral surgical procedures increases and as more advanced magnification tools become available, the adoption of tools to improve visualization has become more and more commonplace. Modern magnification and visualization aids can be utilized to improve clinical outcomes, enhance dental healthcare providers comfort and productivity, and improve the post-operative healing after periodontal procedures. Magnification loupes, microscopes, and enhanced visualization through the use of endoscopic visualization have been associated with enhanced outcomes of most technical dental procedures.1,2 Given the importance of mere millimeters of hard and soft tissue in periodontal regenerative procedures and the challenges with adequate root debridement in closed scaling and root planing, it has been proposed that the use of enhanced visualization techniques are uniquely suited to improve nonsurgical and surgical periodontal procedures. This course seeks to review currently available technologies to enhance visualization and their applications and limitations for periodontal care.
