Abstract EN
Evaluating periodontal tissue condition is an important diagnostic parameter in periodontal disease.
Noncontact electromagnetic vibration device (NEVD) was previously developed to monitor this condition using mechanical parameters.
However, this system requires accelerometer on the target tooth.
This study assessed application of laser displacement sensor (LDS) to NEVD without accelerometer using experimental tooth models.
Tooth models consisted of cylindrical rod, a tissue conditioner, and polyurethane or polyurethane foam to simulate tooth, periodontal ligament, and alveolar bone, respectively.
Tissue conditioner was prepared by mixing various volumes of liquid with powder.
Mechanical parameters (resonant frequency, elastic modulus, and coefficient of viscosity) were assessed using NEVD with the following methods: Group A, measurement with accelerometer; Group B, measurement with LDS in the presence of accelerometer; and Group C, measurement with LDS in the absence of accelerometer.
Mechanical parameters significantly decreased with increasing liquid volume.
Significant differences were also observed between the polyurethane and polyurethane foam models.
Meanwhile, no statistically significant differences were observed between Groups A and B; however, most mechanical parameters in Group C were significantly larger and more distinguishable than those of Groups A and B.
LDS could measure mechanical parameters more accurately and clearly distinguished the different periodontal ligament and alveolar bone conditions.
