Surgical and Endodontic Treatment of Parakeratotic Keratocyst

Türkiye Klinikleri Diş Hekimliği Bilimleri Dergisi, cilt.27, sa.4, ss.729-733, 2021 (TRDizin)

Odontogenic keratocyst (OKC) is categorized as developmental,

noninflamatory cyst that derives from residuals of dental

lamina. In this article, a case of OKC in the mandibular region is

introduced. A 41-year-old female patient with complaints of repeated

swelling and pain between the right and left mandibular second molars

at the mandible was admitted to endodontics clinic. Initial clinical

examination revealed swelling of the vestibular sulcus. The

subsequent radiographic examination showed a uni-locular radiolucency

at the mandible. The electrical pulp test was negative. Root

canal treatment followed by radical curettage was performed surgically

on the lesion region. Histopathological examination showed that

the lesion was a parakeratotic type of OKC. The patient was recalled

after one year and there was no recurrence. However, at the end of 19

months, a new radiolucency was observed on the left mandibular region

which needs further surgical curettage. Long-term (4.5 years)

controls revealed bone formation in the operation field. Periodic follow-

ups of the patient continued.
