Eruption of the Permanent First Premolar Associated With A Mandibular Keratocystic Odontogenic Tumor After Marsupialization in A 9-Year-Old Boy: A Case Report With 2 Years of Follow-Up

Amongst odontogenic cysts, keratocystic odontogenic tumor (kot) is a benign intraosseous lesion, characterized by corrugated parakeratinized uniform stratified squamous epithelium, with potential for aggressive behavior and high tendency to recur. there are multiple treatment modalities for this cyst. some surgeons prefer the conservative treatments such as marsupialization while the others prefer invasive treatments such as radical resection. the aim of this study was to present a case of kot involving the right mandibular premolar area with an impacted tooth in a 9-year-old boy treated by marsupialization. the treatment resulted in eruption of the mandibular first premolar, and no signs of recurrence were observed after two years. marsupialization was found to be an effective treatment in inducing the eruption of mandibular premolar associated with kot in preadolescents and can be a reliable procedure to reduce recurrence tendency of kot.
