“…In this study while ameloblastoma comprised majority (65.6%) of the odontogenic tumors it was slightly below the findings by Simon et al (2005) in which ameloblastoma constituted 80.1% of all odontogenic tumors [11]. Ameloblastoma has also been reported to be the most common odontogenic tumor in several other studies from other countries [2][3][4]8].…”

“…The occurrence of the odontogenic tumors and tumor-like lesions vary from one country to the other. In Tanzania, they were reported to comprise about 12% of all tumors of the orofacial region [2] and elsewhere in Africa, they accounted for 10% to 14% of all orofacial tumors [3,4]. Their prevalence was less than 5% in Brazil, China and Pakistan [5][6][7].…”

“…In Tanzania, ameloblastoma was documented to be the most (73.7%) common odontogenic tumor followed by odontogenic myxoma (10.3%) [2]. Similarly, in Kenya, ameloblastoma was the most (45.9%) common followed by the keratocystic odontogenic tumor (KOT) with 11.2% [3]. While in India odontoma was reported as the most (56%) common odontogenic tumor followed by ameloblastoma (14%), in China KOT was the most (38.73%) frequent benign tumor followed by ameloblastoma (36.52%) [6,9].…”

Introduction: Odontogenic tumors which may be benign or malignant, constitute a group of heterogeneous lesions that are derived from the tooth-producing tissues or their remnants that are entrapped either within the jawbones or into the adjacent soft tissues. Aim of the study was to determine the pattern of occurrence and clinicopathological presentation of odontogenic tumors among patients attending the oral and maxillofacial unit at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania using 2005 WHO classification. Material and Methods: This was a cross-sectional hospital-based study that included patients with oral and maxillofacial tumors. Patients’ information was gathered using a structured questionnaire. Clinical and histological examination was done, and the findings were recorded in a specially designed form. Data was processed and analyzed using Statistical Package for Social Sciences (SPSS) version 19. Results: A total of 102 patients with histological diagnosis of odontogenic tumors comprising 52 (51%) males and 50 (49%) females, were included in this study. The mean age of the patients was 34.07 ± 14.8 SD years and the most affected age group was 20-29 years. Majority 76 (74.5%) of the patients had odontogenic tumors comprised of odontogenic epithelium with mature fibrous stroma without odontogenic ectomesenchyme. Ameloblastoma was the most (65.7%) common odontogenic tumor followed by odontogenic myxoma/myxofibroma (5.9%) and Keratocystic Odontogenic Tumor (5.9%). Conclusion: Generally, the sociodemographic distribution and frequency of occurrence, of odontogenic tumors seen in this study is similar to that reported in other African and Asian studies but differed with American and European studies. Ameloblastoma was the most common odontogenic tumor with a high propensity for the mandible compared to the maxilla.

“…Three studies reported higher prevalence than our: 59% in Turkey (22); 72.5% and 61.4% in Brazil (9,10). The values reported in series using 2005 WHO classification ranged from 38.7% in Kenyans (16) to 64.3% in Saudis (17). A putative explanation to justify this high prevalence of radicular cyst could be related to caries.…”

Prevalence and distribution of odontogenic cysts in a Mexican sample. A 753 cases study

BackgroundOdontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample.Material and Methods753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification. Chi square test was used to establish possible associations (p<0.05IC95%).ResultsFrom 753 OC, 369 were female and 384 male; 52.9% of them were in their 2nd- 4th decade of life. The most common location (41%) was the mandibular posterior area. Radicular cysts were more frequent in maxillary anterior zone of females (p 0.0002) at their fourth decade of life. Dentigerous cysts were more frequent in the mandibular posterior zone of males (p 0.0000) in their second decade of life. Six cases of periodontal lateral cyst; 4 cases of paradental cysts; 4 eruption cysts and 4 cases of adult gingival cyst, as well were identified.ConclusionsRadicular cyst and dentigerous cyst are the most prevalent odontogenic cyst in this Mexican sample. Due to their etiology, dental pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. Therefore, it is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts. Key words:Cyst, dentigerous cyst, mexican, odontogenic cyst, radicular cyst.

“…The duct is known to regress in fetal life, however the persistence of ductal epithelium leads to cyst formation. As it is considered to be the most common non-odontogenic cyst of the gnathic bones [2]. The mean medio-lateral diameter of the incisive foramen ranged from 1.40 mm to 5.90 mm [3], cysts larger than the normal anatomical feature can only be distinguished from incisive foramen.…”
