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.
