Examination of Probing Depth and Tooth Mobility Using a Machine with Voice Input

We evaluated the clinical efficacy of a machine with voice input for examining probing depth (PD) and tooth mobility (TM). Subjects were 4 men and 6 women averaging 24.5 ± 0.7 years of age who had normal dentition and 28 intact teeth with a normal periodontium. Examinations were conducted by 2 dentists-1 with 14 years of clinical experience (Dr-A), and 1 with 1 year (Dr-B) and 3 dental hygienists-1 with 18 years of clinical experience (DH-a), 1 with 7 years (DH-b) and 1 with 4 years (DH-c). We used a machine with voice input (Perionavigation system® : Perionavi (GC Co.)) and a pocket probe (PCPUNC 15, Hu-Friedy Co.). PD was measured at 6 points-esial, central and distal points on facial, palatal and lingual sides. and TM was measured by Miller's classification. We divided subjects into 3 groups: Perionavi use, no Perionavi use and no assistant, and an assistant but no Perionavi use. Statistically analysis was conducted 2-way ANOVA between the 3 groups and 5 dentists/hygienists for the measurement time. For PD, a statistically significant difference (p
