We evaluated the “ Periotest ®” for prosthetic clinical application.Stability and reproducibility of measured value, effect of tapped points and strength of proximal contact on measured value, Periotest value of normal tooth, corelation between Periotestvalue and clinical tooth mobility were investgated.
Periotest values were stabilized during 20 times measurement. Although coefficient of variation of Periotest value measured in premolar and molar were larger than thatin incisor. Good reproducibility were observed in same day and different days. Tapped points and strength of proximal contact affected on Periotest value in incisor and premolar signifficantly. In Feriotest value of normal tooth, maxillaly and mandibular canine tooth were least value, andmandibular tooth were less value than maxillaly tooth. Coreration between Periotest valueand clinical tooth mobility were observed.
From above results, Periotest was useful disgnostic machine for dynamic periodontal condition with limitted use.
