Application of ultrasonic bone knife in extraction of impacted mandibular teeth
To investigate the effect of ultrasonic osteotome in the extraction of impacted mandibular teeth.
Methods
2
According to different extraction methods
82 patients with impacted mandibular teeth who were treated in Yingcheng People's Hospital
Hubei
China
from June 2021 to June 2022 were divided into the control group (
n
=40) and observation group (
n
=42). The control group was extracted by conventional turbo drill
while the observation group was extracted by ultrasonic bone knife. The two groups were compared in terms of surgery⁃related indicators
clinical treatment effect and postoperative pain (visual analogue scale (VAS))
swelling and mouth opening limitation recovery. The expression level of inflammatory factors in gingival crevicular fluid
such as tumor necrosis factor‑α (TNF‑α)
intercellular adhesion factor 1 (ICAM1)
and myeloperoxidase (MPO)
as well as the occurrence of complications were compared between the two groups.
Results
2
The operation time and intraoperative blood loss in the observation group were less than those in the control group (
P
<
0.05). After operation
the systolic blood pressure
diastolic blood pressure and blood glucose level in both groups were increased (
P
<
0.05)
but the changes were less in observation group than in control group (
P
<
0.05). The excellent and good rate of treatment in the observation group was 97.62%
which was higher than 82.50% in the control group (
P
<
0.05). The VAS score
swelling degree and mouth opening restriction rate in the observation group were lower than those in the control group (
P
<
0.05). Three days after operation
TNF⁃α
ICAM1
and MPO in the control group were increased and were higher than those in the observation group (
P
<
0.05). The incidence of complications in the observation group was lower than that in the control group (
P
<
0.05).
Conclusion
2
Ultrasound osteotome is effective in the treatment of impacted mandibular teeth with short operation time
minimal trauma
and low incidence of postoperative pain
swelling and mouth opening limitation. It can also improve the inflammatory reaction of the gingival crevicular fluid and reduce the risk of complications.
