Abstract
Odontomas are benign tumors of odontogenic origin characterized by their slow growth. They are considered to be a common type of odontogenic tumor, but rarely occur in the primary dentition.The etiology of odontomas is unknown, although local trauma, infection and genetic factors have been suggested. Odontomas often cause disturbances in the eruption of teeth such as, impaction or delayed eruption, and retention of primary teeth and abnormalities in the position of teeth such as tipping or displacement of adjacent teeth. In this paper, a case of unerupted right mandibular primary cuspid in a 5 years old girl due to the presence of a compound odontoma is presented.

Abstract
Background and Aims: Central odontogenic fibroma is a rare odontogenic neoplasm that originates from odontogenic ectomesenchyme. Most cases occur in the mandible and between the ages of 11 and 39 years. The neoplasm shows a definite female preponderance, with a ratio of 2.2:1 and has a very low recurrence rate. The aim of this article was to report a case of this rare lesion which was accidentaly found.
Case Report: A 11-year-old female, during her orthodontic treatment and without any complain and any sign or symptoms, performed a panoramic image for assessing the permanent teeth buds. In the panoramic view a unilocular radiolucent lesion with well-defined and corticated borders in the right mandibular body region was evident. The lesion was treated with simple excision. Simple type of central odontogenic fibroma histopathologic features was observed in the microscopic view.
Conclusion: Although the central odontogenic fibroma is a rare benign neoplasm, however, a careful evaluation of radiographic images is important for early detection of lesions because the patient may have no clinical symptoms such as swelling, pain and paresthesia.

Abstract
Ameloblastoma is one of the most common benign tumors originating from odontogenic tissues. Despite being benign, it has a locally aggressive behavior and a high tendency to relapse. While, this tumor is mainly found in the posterior region of the mandible, its occurrence in the maxilla is rare and is associated with more diagnostic and therapeutic challenges. This report presents a rare case of ameloblastoma in the maxilla of a 64-year-old male patient who presented with painless swelling and significant extension of the lesion to the midpalate. Clinical, radiological, and histopathological findings were reviewed and after necessary evaluations, the diagnosis of ameloblastoma was confirmed. The anatomical complexity of the maxilla, proximity to vital structures, and surgical limitations make the management of these tumors more difficult. The present report emphasizes the importance of early diagnosis, careful histological examination, and the need for a multidisciplinary therapeutic approach in dealing with this type of tumor.
