Abstract
Considering the robust awareness of early detection among oral clinicians and patients the increasing imposition of better methods for screening of oral precancerous/cancerous lesions has become imperative. Although histopathology has been considered the indispensable gold standard, it has its pros and cons, as sometimes the diagnosis is compromised with the variabilities subject to the histopathologist under concern. In the realm of oral healthcare, one pioneering trailblazer is making waves, which are 'quantum dots'. Quantum dots are poised to transform the landscape of oral precancer and cancer screening. These nano-sized semiconductor particles possess extraordinary properties that set them apart from conventional detection methods. Their ability to emit distinct wavelengths of light when excited makes them ideal candidates for early detection. The keywords were pitched in and the research literature from the last 15 years (2008-2022) was extirpated to find out the information that existed, the discrepancies and the void left for upcoming research. Its nature and ingenuity have given rise to a transformative approach that holds the potential to redefine the future of oral healthcare. With each breakthrough, we edge closer to a world where the early detection of oral precancerous/cancerous lesions becomes the norm rather than the exception.
