Usage of 5-fluorouracil and Carnoy's Solution in Surgical Treatment of Odontogenic Keratocysts

Phase 4
Conditions
Odontogenic Keratocyst
Interventions
Procedure: Enucleation
Diagnostic Test: incisional biopsy
Drug: Application of Carnoy solution
Registration Number
NCT06096220
Lead Sponsor
University of Belgrade
Brief Summary

The goal of this clinical trial is to compare surgical treatment outcomes of odontogenic keratocysts (OKC) treated with enucleation and local application of Carnoy's solution or 5% 5-fluorouracil. The main questions it aims to answer are:

1. What is the recurrence rate of OKC treated with enucleation and local application of 5% 5-fluorouracil cream in the period of three and five years after the treatment

2. What is the recurrence rate of OKC treated with enucleation and local application of Carnoy's solution in the period of three and five years after the treatment

3. Is there a difference in the recurrence rate between these two groups

4. What is the frequency of sensitivity disorders in the innervation zone of inferior alveolar and infraorbital nerves in both groups

Participants will be assigned to one of two groups after Histopathological verification (HP verification).They will be treated with enucleation and local application of Carnoy's solution or 5% 5-fluorouracil depending on group. After surgical treatment they will be monitored in accordance to standard treatment protocols for patients with OKC.
