MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202621009703 A) filed by Gowri Swaminatham Pendyala, Ahmednagar, Maharashtra, on Jan. 30, for 'periodontal curette with integrated mirror and targeted illumination for subgingival visualization.'
Inventor(s) include Gowri Swaminatham Pendyala; Dr. Preeti Astagi; Dr. Dhananjay Gandage; Dr. Vikas Madhavrao Attargekar; and Principal, Rural Dental College.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a periodontal hand instrument, namely a periodontal curette with integrated mirror and targeted illumination for improved subgingival visualization during periodontal treatment. The instrument comprises a handle, a shank, and a curette blade terminating in a working edge for scaling and root planing. The mirror is fixedly positioned adjacent to the working end to enable indirect visualization of subgingival, posterior, and furcation areas without altering instrument orientation. A focused illumination source, preferably a micro light-emitting diode, is arranged near the mirror to direct light precisely onto the operative site within periodontal pockets. The illumination is powered by an internal power source housed within the handle and operated via a control mechanism. The integrated configuration enables simultaneous instrumentation, illumination, and visualization, thereby enhancing clinical accuracy, ergonomics, and procedural efficiency while overcoming limitations of conventional curettes requiring separate mirrors and external lighting."
