Rare jaw bone tumor: The importance of multidisciplinary management and minimally invasive treatment

Objective: The aim of this study was to present a mini review of oral Cementoblastoma and to report a particular case of this tumor. The Cementoblastoma is a rare benign lesion that represents less than 1-6% of all odontogenic tumors. Cementoblastoma, in the current WHO classification of odontogenic tumors, falls under the category of mesenchymal tumors (WHO 2017) and it is characterized by the proliferation of cementum-like tissue and, in all cases, tends to be associated with an erupting permanent tooth, most often the first molar. Case Presentation: A 15-year-old female presented a great Cementoblastoma with cortical expansion that affected the left mandibular body, extending from the canine to the first premolar (size 28x24 mm) and involving the mandibular canal. Surgery was performed under general anesthesia with total excision of the lesion, which was then sent for histological analysis. Due to the high risk of nerve injuries and the extreme fragility of the remaining bone after surgery, which required plates and intermaxillary blockage, the surgical site was regenerated with an iliac crest graft together with autologous and synthetic bone. Results: For the mini-review, 107 articles were found, but only 26 were selected. The patient was monitored for 12 months after surgery; a perfect healing was reported without complications, and she showed no signs of recurrence. Conclusions: This case report emphasizes the usefulness of clinical choices in a rare case of cementoblastoma of great size in a very young patient. In this condition, finding the most effective eradicative and reconstructive treatment, following the last published protocols, could achieve optimal clinical and psychological patient outcomes.
