Retrospective clinicopathological study of 418 odontogenic cysts

Abstract

Objectives: To determine the relative incidence of odontogenic cysts and to identify the main clinicopathological features among patients treated in the Oral Surgery Department of the Dental Clinic of the University of Barcelona (Spain). Study design: A retrospective observational study was made of 418 odontogenic cysts diagnosed in 380 patients included in the database of 1235 histopathological diagnoses. The subjects were treated in the Master degree program of Oral Surgery and Implantology of the University of Barcelona in the period 1997-2006. The following variables were recorded: gender, age, clinical characteristics of the lesions (size and location), radiological features, duration, treatment, complications and relapses. A descriptive analysis was made of the study variables, using the SPSS version 15.0. Results: The incidence of odontogenic cysts was 33.8%. The mean patient age at appearance of the lesion was 42 years (range 7-83). The cysts were slightly more prevalent in males (58.4%). The lesion size ranged from 2-60 mm, with a mean size of 18.4 mm. The most frequent diagnosis was radicular cyst (50.2%). The most common location of the odontogenic cysts was in the mandible (61.5%), particularly the lower third molar region (36.8%). Conclusions: The most frequently diagnosed lesion was the radicular cyst. Odontogenic cysts were seen to be slightly more prevalent in males, and showed a high mandibular incidence. Knowledge of the biological and histological behavior of odontogenic cysts and their frequency are key aspects for ensuring early detection and adequate treatment.

The relevance of clinical and radiographic features of jaw lesions: A prospective study

“…In a study conducted by Núñez-Urrutia et al 9 , 61.5% of bone lesions occurred in the mandible. Paradental cysts (97.7%) and dentigerous cysts (69.2%) were observed more in the mandible, while radicular cysts were observed more in the maxilla (56.2%).…”

“…In addition, JL represent a wide spectrum of diseases/alterations, and epidemiological studies simultaneously evaluating all of these lesions are uncommon. In general, the data are presented according to the following groups: odontogenic cysts and tumors 3,8,9,10 , fibro-osseous lesions 11,12,13 , malignant tumors 14,15,16,17 , and osteonecrosis 18 . The present study was prospectively designed with the purpose of determining the prevalence of these types of lesions.…”

“…A retrospective study evaluated 418 cases of odontogenic cysts in the period from 1997 to 2006 and found that 210 cases were periapical cysts (50.2%) and 91 (21.8%) were dentigerous cysts. 9 There are a large number of odontogenic tumors; more than 20 types according to the WHO (2005). Some studies have shown ameloblastoma 2,3,20 to be the most common tumor, whereas odontoma has been more frequent in others 21,22 .…”

Clinicopathological Evaluation of Odontogenic Jaw Cysts

“…In anterior maxilla, radicular cysts were more common. Odontogenic keratocyst was more common in the posterior mandible [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][22][23][24][25] . In the present study Shows that according to radiological feature 79% (n=49) lesions had unilocular radiolucency and rest of 21% (n=13) lesions had multilocular radiolucency.…”

Analysis of 153 cases of odontogenic cysts in a South Indian sample population: a retrospective study over a decade

“…Inflammatory odontogenic cysts are formed due to activation of these cell rests by an inflammatory process. 1 Developmental and inflammatory odontogenic cysts are epithelial in origin, exhibiting slow growth and a tendency towards expansion. However, despite their benign biological behavior, these lesions can reach a marked size if they Declaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”
