Prevalence and distribution of odontogenic and nonodontogenic cysts in a Turkish Population

Abstract

Objective: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. Study Design A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayıs University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. Results: The prevalence of odontogenic and nonodontogenic cysts was 3.51%; males were affected more frequently than females. There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%). Nasopalatine duct cyst (1.5%) was the only nonodontogenic cyst. By age, cysts peaked in the third decade (24.2%). Concerning location, no statistically significant difference was found between the maxilla and mandible (p>0.05). The most frequent radiological feature of these lesions was unilocular cyst (93.7%). Pathologies associated with cystic lesions occurred in 14.7%. Conclusion: The prevalence of both odontogenic and nonodontogenic cysts were lower than that reported in many other studies. In our study population, cysts were mainly inflammatory in origin. Key words: Prevalence, odontogenic, nonodontogenic, cysts.

Diagnostic sensitivity and specificity in a retrospective clinical, radiographic and histopathological study of 166 cystic jaw lesions

“…Multicystic lesions were most frequently seen in cases with KCOT. This is in accordance with previous studies.…”

“…Studies of cystic jaw lesions have been reported from several different countries including Turkey, Spain, Brazil, Mexico, United Kingdom, Canada, Italy and Chile (Table ). It is evident that there are differences in diagnoses depending on patients' demographic characteristics, socio‐economic factors and availability of dental care.…”

Cysts of the Orofacial Region: A 35 Year Demographic Data at an Indian Dental Institute.

“…21,32,35,41,27 Ioannidou et al 20 found it to be the second most common odontogenic cyst (28.4%). The prevalence was higher than Prockt et al 43 (4.26%), Meningaud et al 32 (4.6%), Ledesma Montes et al 27 (4.9%) and almost similar to Saghravanian et al 38 (6.5%), Al Sheddi et al 3 (6.6%), Jones et al 21 (8%) and Tekkesin et al 53 (9.63%).The prevalence was lower than that reported by Ochsenius et al 41 (11.1%) and Acikgoz et al 1 (13.7%). Ledesma Montes et al 27 found that residual cysts occurred in women more frequently which differed from our finding as well as studies in the literature which showed male predominance.…”

“…However in the study by Daley et al aneurysmal bone cyst and traumatic bone cysts were not included, as they are considered as pseudocysts that fail to satisfy the definition of a cyst. In a study by Acikgoz et al 1 the prevalence of orofacial cysts and odontogenic cysts was very low accounting to 3.72% and 3.65% respectively. (Table 7) Of the total of 1242 cases of cysts of the orofacial region, the jaw cysts accounted to 86.71% of which 98.79% were of odontogenic origin and 1.21 % was of non-odontogenic origin, cysts of the maxillary antrum was 0.32%,while cysts of the soft tissues of the mouth, face,neck and salivary glands was 12.96%.…”
