Comparison Between Using Erbium(Er):YAG laser and Surgical Burs in Bone Removal Around Impacted Lower Third Molars

The aim of this study was to compare the pain and the time consumed during surgical extraction of the impacted lower third molars using Er:YAG laser and surgical burs. The study included 40 impacted molar existed in 20 patients (11male + 9 female) who had two symmetric impacted lower molars. The time consumed during the extraction was measured and the pain was observed during one, three and seven days after the surgical operation. After that the data were statistically studied. As a result of this study, the mean of the time consumed in bone removal was (9.5) minutes using surgical burs and (15.7) minutes using Er:YAG laser. So there was significant difference between the two methods. There was no significant difference in pain between the two methods during the three observation periods. Based on the results of this study, the use of Er:YAG laser as an alternative method to the surgical burs is possible but it consumes a lot of time during bone removal.
