Usage of 5-fluorouracil and Carnoy's Solution in Surgical Treatment of Odontogenic Keratocysts
Study Details
Study Description
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:
-
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
-
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
-
Is there a difference in the recurrence rate between these two groups
-
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.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Experimental group Enucleation of OKC followed by local application of 5% 5-fluorouracil cream. Drug will be applied on the gauze left in the enucleation defect for 24 hours, after which the gauze will be removed. |
Procedure: Enucleation
Enucleation is complete removal of the cyst from the bony defect of the jaw affected by the lesion. Osteotomy is performed to allow access to the cyst, cystic wall is detached from the bone and removed completely.
Diagnostic Test: incisional biopsy
Lesions clinically abd radiographically consistent with OKC will be submitted for histological examination to confirm the diagnosis of OKC
Drug: Application of 5-fluorouracil
5% 5-fluorouracil cream will be applied immediately after the enucleation to the cystic cavity for 24 hours
|
| Active Comparator: Control group Enucleation of OKC followed by local application Carnoy solution. Carnoy solution will be applied into the cystic cavity for 5 minutes and bone defect will be treated by Carnoy solution for 3 minutes immediately after the enucleation. |
Procedure: Enucleation
Enucleation is complete removal of the cyst from the bony defect of the jaw affected by the lesion. Osteotomy is performed to allow access to the cyst, cystic wall is detached from the bone and removed completely.
Diagnostic Test: incisional biopsy
Lesions clinically abd radiographically consistent with OKC will be submitted for histological examination to confirm the diagnosis of OKC
Drug: Application of Carnoy solution
Carnoy solution will be applied during the enucleation as described previously
