Abstract

Background:  To compare piezoelectric with conventional rotary surgical technique for mandibular cyst enucleation in relation to wound dehiscence, infection, pain, paraesthesia, bone density and duration. Patients and methods: We conducted a parallel arm double blind control trial on a convenience sample of 24 patients. Piezosurgery for the study group and curettage for the control group were performed. Both the groups were compared for post-operative wound dehiscence, infection, pain, paraesthesia, bone density and duration of procedure.  Results: The two groups did not differ in their demographic characteristics. While pain on 3rd post-operative day (t= -5.17, p=0.00) was significantly greater in the control group, bone density at six months (1576 HU vs 1363 HU, t= 4.17, p=0.00) and duration of procedures (107 min vs 60 min, t= 6.14, p=0.00) was significantly higher for the study group. There was no significant difference in wound dehiscence (p= 0.21,3rd post-operative day), paraesthesia (p= 0.47, 45th post-operative day) and infection (p=0.21, 7th post-operative day) between the groups.  Conclusion: All the results except duration, were in favour of piezo-surgery thus making it a safer alternative to conventional rotary surgery. The associated advantages cover up for the longer duration.
