Tissue mimicking materials for dental ultrasound

Abstract

While acoustic tissue mimicking materials have been explored for a variety of soft and hard biological tissues, no dental hard tissue mimicking materials have been characterized. Tooth phantoms are necessary to better understand acoustic phenomenology within the tooth environment and to accelerate the advancement of dental ultrasound imaging systems. In this study, soda lime glass and dental composite were explored as surrogates for human enamel and dentin, respectively, in terms of compressional velocity, attenuation, and acoustic impedance. The results suggest that a tooth phantom consisting of glass and composite can effectively mimic the acoustic behavior of a natural human tooth.

Investigation of Therapeutic Ultrasound Dose on Muscle Phantom: An Experimental Study Investigation of Therapeutic Ultrasound Dose

“…The speed of sound was 1549.8±3.8 m/s (U=6.7), which was consistent with the Mast's data, 1547 m/s. According to Mast , the attenuation coefficient of muscle tissue is 1.09 dB / cm MHz, while various values such as 1.1 dB /cm MHz have been reported in the literature (21). These figures are similar to the attenuation coefficient we measured at the end of the investigation, 1.14±0.8 dB / cm MHz (U =0.55).…”

Ultrasonic monitoring of the effect of sodium hypochlorite on the elasticity of dentine

“…, John , Singh et al . ). This variation may be due to anisotropy, age, type and location of dentine (Lees & Rollins , Kinney et al .…”

Optical comparison between micro‐CT and OCT in imaging of marginal composite adaptation: Observational study

“…Dye and tracer penetration tests, followed by microscopic evaluation are destructive imaging techniques that require specimen sectioning and preparation 10–12 . On the other hand, ultrasound imaging is a nondestructive technique that relies on the penetration of sound waves through a matter, revealing the deep internal structures noninvasively 13 . However, the increased imaging depth will decrease its resolution, which will limit its usefulness in the dental field.…”

“…The Fourier domain system process series of raw A‐scans into depth information to form a single greyscale B‐scan data instantly. The main advantage of this system is that it provides tissue morphology and optical biopsy in real time and in contactless mode, using non‐ionising radiation at higher resolution, unlike magnetic resonance imaging and ultrasounds 13,20 …”
