Studies on the changes in biomechanical properties of the gingiva are significant, since they are closely related to the pathological process of gingivitis and periodontitis. Although some research has been conducted, the currently used techniques are not feasible for in vivo and clinical measurements due to their disadvantages, such as the invasive nature and the requirement of thin sectioning. In this study, we developed a shaker based optical coherence elastography system which provides noninvasive measurement, high axial resolution, high displacement sensitivity, and real-time imaging, and explored its potential for the detection of gingival elasticity. The system was tested by an agar phantom model and an in vivo rabbit model, where the shear wave propagations were visualized and the corresponding shear modulus and Yong's modulus were quantified, suggesting the feasibility and reliability of our system. As far as we know, this is the first in vivo elasticity imaging of the gingiva, thus providing a powerful tool for rebuilding gingival elasticity, which may widely benefit clinical medicine in the future.
