Odontomas are considered to be hamartomatous malformations rather than true neoplasms. This most common odontogenic lesion results from the growth of completely differentiated epithelial and mesenchymal cells that give rise to ameloblasts and odontoblasts. Dentigerous cyst is an epithelium-lined sac enclosing the crown of an unerupted tooth. Apparently, the dentigerous cyst arises by the accumulation of fluid between reduced enamel epithelium and the tooth crown. Occasionally it is associated with supernumerary tooth or odontoma. We report a case of dentigerous cyst associated with complex composite odontoma and an impacted lateral incisor in a 30-year-old male patient.

    • "Odontomas are reported to be associated with calcifying odontogenic cyst[1314] and dentigerous cyst.[41516] The development of OOC has been postulated to be from the remnants of dental lamina, whereas odontomas are considered to be arising from hyperactive dental lamina.[1117] "

    ABSTRACT: The orthokeratinized odontogenic cyst (OOC) and odontoma are the odontogenic cyst and tumor respectively that are minimally invasive neoplasms of head and neck region. OOC is a rare variant of odontogenic cyst characterized by the presence of excessive orthokeratin covering the cystic lining. Odontoma is a benign neoplasm/hamartoma often discovered accidently on panoramic radiographs. We came across a case of a 26-year-old male with swelling on his face along with difficulty in breathing. On the basis of radiographic and histopathological findings the final diagnosis of OOC associated with odontoma was given. However, there is no report in the English literature of the simultaneous occurrence of these two lesions and hence this case is very rare. It is unclear whether the two lesions were just coincidental or were actually related to each other.

    • "In general, they constitute 22% of all odontogenic tumors of the jaws.7 The etiology of odontoma is unknown, but genetic factors, family history, and environmental causes such as trauma and infection have been suggested.1,5,6,8 The radiographic findings of odontomas depend on their stage of development and degree of mineralization.

    ABSTRACT: The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

    • "Another reason for removing odontomas is their association with cysts in a significant number of cases (27.6%). Looking at the association of these lesions and the potential complications associated with the cyst, odontomas should be properly evaluated and removed completely in case of any suspicion of cystic transformation.[17] In cases where smaller segments are left behind, they do not tend to grow or get infected postoperatively.[18] "

    ABSTRACT: The occurrence of complex odontomas is not considered to be rare in the jaws. But the occurence of large odontomas obscuring the maxillary sinus, or erupting into the oral cavity are considered to be rare. The prognosis is good with surgical excision and recurrence is nil. Most of the times the surgical site can be closed primarily, but sometimes requires local flaps to achieve tension free closure. Here, we report such a case treated by surgical excision trans orally followed soft tissue defect reconstruction with pedicled palatal island flap.
