Surgical outcome after impacted mandibular third molar surgery using piezotome and conventional rotary handpiece: a comparative study
Keywords:Bilateral impaction, Piezotome, Rotary handpiece
Background: This study was performed to compare the surgical outcome in impacted mandibular third molar surgery using piezotome and conventional rotary handpiece.
Methods: Total 40 patients were selected with similar Pederson Index for mandibular third molar surgery with either piezosurgical unit or conventional rotary handpiece. Pain, trismus, oedema and alveolar osteitis were evaluated preoperatively and then postoperatively 1st, 3rd, and 7th day.
Results: Statistical analysis showed that the average time needed to complete the osteotomy and extraction was significantly lesser for the rotary group than for the piezo group (p<0.05). The average duration of surgery was 18.16 minutes in group A, and 20.49 minutes in group B.
Conclusions: Significantly lesser pain, trismus, facial swelling, alveolar osteitis and a better perception of the quality of life by the patients after third molar extraction was found using the Piezotome.
