The benign cementoblastoma is a rare odontogenic tumor of mesenchymal origin and is a true neoplasm of cementum which has an unlimited growth potential. The etiology is still unknown and controversial. It is most common in men below 25 years of age and occurs commonly in mandibular premolar-molar area. Clinically, the cementoblastoma is characterized by painless bony expansion and often detected during routine oral examination. Radiologically, it appears as a radiopaque mass surrounded by a thin radiolucent line and associated with the roots of a tooth. Histopathologically, it is characterized by a cellular fibrous stroma and calcified cementum or cementum-like portion which has numerous reversal lines. Because of the unlimited growth potential, complete excision of the tumor with the involved tooth has been recommended. These reports are two cases of benign cementoblastoma occurred in the right mandibular first molar area of 17-year old male patient and in the left mandibular second molar area of 24-year old male patient. They underwent the complete excision of the tumor with the involved teeth. On follow-up check, it revealed good bony healing and no recurrence on the operated sites.
