NCT02495207.

Study name	A comparison between conventional surgery and piezosurgery
Methods	Parallel RCT
Participants	15 participants
Interventions	Piezosurgery
Outcomes	Primary outcome measures: levels of heat shock protein 70 (time frame: 5 minutes before third molar removal with the last removed layer of bone). This will be measured using ELISA (enzyme‐linked immunosorbent assay) methodology. Secondary outcome measures: percentage of viable bone cells (time frame: this variable will be measured from the specimens taken within the first 15 minutes of bone cutting to remove third molars). Percentage of viable bone cells will be calculated based on the counts of viable bone cells observed under the microscope.
Starting date	19 June 2015
