Odontogenic tumors in an Iranian population: a 30-year evaluation
Journal of Oral Science, 2010
Oral and maxillofacial pathology has paramount importance in connecting basic science and clinical features; progress in this field will improve diagnosis and treatment. Although the prevalence of odontogenic tumors varies in different geographic sites, there are no reports in English on the relative frequency of odontogenic tumors in Iran. In the present 30-year retrospective study, the case records of all patients referred to the Mashhad Faculty of Dentistry during the period 1978-2008 were evaluated. Subsequently, all lesions diagnosed as odontogenic tumors were subjected to microscopic reevaluation. Data regarding sex, gender, location, and histopathology were gathered. Among 8,766 patients, only 165 odontogenic tumors (1.9%) were found, with a mean age of 26.3 years (range 6-81 years). One hundred and fifty-eight tumors were central with high frequency in the posterior region of both jaws especially in the mandible and seven were peripheral tumors, including five in the posterior mandible and two in anterior maxilla. Malignant transformation was seen in three cases as malignant ameloblastoma (1.8%). The most common tumor was ameloblastoma, followed by odontoma, odontogenic myxoma, and adenomatoid odontogenic tumor. Nevertheless, odontogenic tumors occurred more in females in the third decade with affinity for the posterior mandible in this study.
Odontogenic tumors: An 11‐year international multicenter study
Oral Diseases, 2020
Cases of OTs were selected and classified according to the current WHO classification (2017) (Wright and Vered, 2017). The hematoxylin and eosin-stained sections were re-evaluated. Data regarding histopathological type, gender, age and anatomical site, were obtained from patient records. The cases of OTs were divided according to the oral pathology center and its corresponding geographical areas. Based on the 10-year analysis, Brazil 1 was the center with the highest number of cases of OTs (437 cases), followed by Israel (163 cases), Finland (115 cases), and Brazil 2 (108 cases).
Odontogenic tumors in Ethiopia: eight years retrospective study
BMC Oral Health, 2017
Background: Odontogenic tumor (OT) comprises a large heterogeneous group of lesions arising from tooth producing tissues or its remnants. Studies on OTs are scarce in Ethiopia. Thus, the present study aimed to assess the pattern of OTs in Ethiopia. Methods: An 8 years retrospective study was conducted at the Dental and Maxillofacial Department, St. Paul's referral hospital, Addis Ababa, Ethiopia. Data were collected by reviewing the medical records of patients who visited the Department from September 2008 to August 2015. All the collected data were coded, checked, edited and entered to SPSS windows 18. Lastly, descriptive statistics, and logistic regression were performed for data analysis. Results: A total of 448 patient's socio-demographic, and clinical data were reviewed from the registry book of patients diagnosed with OT. Of these, only 163 patient's records were complete and suitable for the study. 88 (54%) of the study subjects (163) were males, while the remaining 75 (46%) were females. The mean age of patients was 34, ranging between 8 and 80 years. 132 (81.0%) of the OTs were benign, and the rest 31 (19.0%) were malignant type. 126 (77.3%) of OTs occurred in the mandible, and the remaining 37 (22.3%) were located in the maxilla. 135 (82.8%) of the patients had primary surgical treatment. Continuity defect, facial disfigurement and malocclusion were the most frequently encountered complications after surgery. Living in rural areas showed statistically significant association with complication after surgery [Adjusted OR = 2.13, (95% CI: 0.98, 4.6)]. In addition, tumor size had statistically significant association with complication after surgery [Adjusted OR = 4.24, (95% CI: 1.76, 10.21)]. Conclusion: OTs were mainly found in males than their females counterpart. Benign OT was predominant over malignant OTs. Regular checkup and/or visit to dentists could help early case detection, and management of OTs.
Odontogenic tumors: A retrospective study from a tertiary-level hospital in Dhaka, Bangladesh

Odontogenic tumors (OT) are lesions that originate from epithelial, ecto-mesenchymal, and/or mesenchymal tissues that are involved in the odontogenic process. [1] These lesions originate from the dental lamina or any of its derivatives. These are relatively rare lesions, and malignant tumors are exceptionally uncommon.

The objective of this study was to analyze the frequency and distribution of odontogenic tumors (OTs) in the Cappadocia region of Turkey, and to compare the findings with those reported in the literature. The records of the Oral and Maxillofacial Surgery and Pathology Departments at Erciyes University, with histologic diagnosis of odontogenic tumors (based on the World Health Organization classification, 2005), over a 12-year period, were analyzed. The relative frequency of different types of tumors was also analyzed and compared with the literature. OTs in the present study constituted 2.74% of all the 7,942 registered biopsies. A total of 218 cases of OTs were collected and reviewed. Of these, (94.04%) were benign and (5.96%) were malignant. The mandible was the most commonly affected anatomic location, with 170 cases (77.9%). Ameloblastoma with a predilection for the posterior mandible was the most frequent odontogenic tumor (30.28%), followed by keratocystic odontogenic tumor (1...

with histologic diagnosis of odontogenic tumors (based on the World Health Organization classification, 2005), during a 15-year period, were analyzed. Results. A total of 82 cases of odontogenic tumors were reported. Of these, (96.3%) were benign and (3.7%) were malignant. Ameloblastoma (41.5%) was the most frequent type, followed by keratocystic odontogenic tumor (19.5%), odontoma (13.4%), and odontogenic myxoma (8.5%). The mean age of the patients was 29.57 years, with a wide range (4-80 years). Conclusions. Odontogenic tumors show a definite geographic variation. In Dakahlia, Egypt, ameloblastoma and keratocystic odontogenic tumor are the most frequent odontogenic tumors, with distinct anatomic predilections.

Odontogenic tumors: a study of 250 cases in an Indian teaching hospital
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2008
Studies on odontogenic tumors published from many parts of the world show a distinct geographic variation. But there is little information available in the English-language literature on the relative frequency of odontogenic tumors in India. This retrospective study was designed to determine the relative frequency of odontogenic tumors in an Indian teaching hospital and compare them with various reports from other parts of the world. Study design: The pathology records of the Department of Oral Pathology, Nair Hospital Dental College, from January 1971 to December 2006 were reviewed retrospectively, and based on World Health Organization classifications, 1992, we reclassified and analyzed the odontogenic tumors. The mandible and maxilla were divided into 7 anatomic regions, and the distribution of each odontogenic tumor among these regions was recorded and analyzed. Results. A total of 250 cases of odontogenic tumors were reported in the 36-year period. Of these cases, 98.8% of the tumors were benign. The most frequent histologic type was ameloblastoma (61.5%), followed by adenomatoid odontogenic tumor (12.4%) and myxomas (6%). Odontomas, which are reported as the most frequent odontogenic tumor in American and European case reports, only accounted for 6%. In general, the odontogenic tumors showed a predilection for the mandible and the posterior regions of the jaws. Ameloblastomas occurred with a marked predilection for the mandible with a ratio of 18.1:1. But adenomatoid odontogenic tumor showed predilection for the maxilla, anterior regions of the jaws, and young females. Conclusions. Odontogenic tumors show a definite geographic variation. In India, ameloblastoma and adenomatoid odontogenic tumor are the most frequent odontogenic tumors, with distinct anatomic predilections.
