Investigation of the Effect of Scan Delay on the Measurement of Dental Prescale II

Dental Prescale II (GC Corp., Tokyo) is a pressure sensitive sheet for occlusal force measurement. According to the instruction, the patient need to bite the sheet for about 3 seconds and then the sheet will be scanned. But the delay response of coloring agent will influence the data collected and was noticed in vitro. To have a standard procedure, we need to know the time for scanning. This study will scan the sheet up to 2 hours and try to find the relation between the time the sheet scanned and the data collected.

Dental Prescale II

Device

The participant will bite Dental Prescale II for about 3 seconds, using a force for " chewing beef ". And the Dental Prescale II will be taken out from the mouth. Then the trial is end.

Primary outcomes

The relation between occlusal force and scanning time

Time frame: immediately after the intervention

After Dental Prescale II is used and cleaned, the first time of scanning will be defined as 0 min. The pressure sensitive sheet will be scanned every minute during 0~15 minutes, and at 30, 60, 90 and 120 minutes.
