“…Over the past four decades, many researchers have explored the use of diagnostic ultrasound to image the periodontal region [29][30][31][32][33][34][35][36][37][38]. In 1998, Loker and Hagenbuch developed a prototype of an ultrasonic device to measure the depth of the periodontal pocket [39]. Their device used a solid taper-delay line to couple the ultrasound into the tissue at approximately the same location and orientation as manual probing [40].…”

Periodontal disease is one of the most pervasive dental diseases in older adults. It involves the loss of connective tissue attachment with subsequent destruction of tooth-supporting bone, leading to loss of teeth. Periodontal pocket depth is currently measured with an invasive manual probe, but adapting diagnostic ultrasound to this purpose can avoid the pain and inaccuracy inherent in manual probing. In this paper, 3D simulations of ultrasonic periodontal probe measurements are described, using a parallel finite integration technique which is adaptable enough to create realistic anatomical geometries. The outputs of the simulation include 3D pressure values distributed throughout the periodontal anatomy, 2D vertical cross sections of the acoustic pressure waves, and the pressure across the face of the transducer which is used to synthesize the ultrasonic echo. Experimental comparison with a simple phantom is also shown. Lastly, the energy values for different simulations are calculated from the 3D pressure values to describe the amount of energy reaching different zones, especially the junctional epithelium. The simulations as well as the energy studies show that only a small portion of the ultrasonic energy is reaching the junctional epithelium, and so sophisticated mathematical techniques are required to ultrasonically measure pocket depth.

“…A loss of over 2 mm must occur before further loss of attachment can be reliably diagnosed as having taken place at a site. Most investigators agree that an alteration of 2-3 mm is an indicator of a significant anatomic change [73]. The ultrasonographic periodontal probe offers the potential to detect much smaller increments of anatomic change in pocket depth, thereby promising earlier detection of tissue breakdown and faster intervention.…”

[1][2][3][4][5][6]9,[12][13][14][15][16][17] Loker and Hagenbuch [18] constructed a prototype ultrasonic periodontal diagnostic instrumentation system, which includes a commercial pulser-receiver, signal conditioning, and an oscilloscope.…”

& The aim of this study is to design and implement a noninvasive ultrasonic thickness measurement device that determines the gingiva thickness, which is quite an important criterion in dentistry, by using A-mode ultrasonic method. Operating frequency of the device is selected as 8 MHz, since gingival thickness is quite slight. The measurements are performed as 192.5 lm precision by the implemented system. Surface-mounted devices integrated circuits (SMD ICs) and electronic parts are used in the implementation of the device. Thus, a small-dimension, handheld device has been design and constructed. The transmitter of the device is tested under simulated object, and encouraging results were obtained.
