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

Abstract

Analysis of 153 cases of odontogenic cysts in a South Indian sample population: a retrospective study over a decade Abstract: The purpose of this study was to determine the prevalence of odontogenic cysts and to identify their clinico-pathological features among patients by studying biopsy specimens obtained from the archives of the Department of Oral and Maxillofacial Pathology, College of Dental Sciences, Davangere, Karnataka, India, during the past 10 years. Data for the study were retrieved from the case records of patients fitting the histological classification of the World Health Organization (1992). Analyzed clinical variables included age, gender, anatomical location, and histological diagnosis. Of the 2275 biopsy reports analyzed, 194 cases (8.5%) were jaw cysts, including odontogenic (6.7%) and nonodontogenic cysts (0.25%). Odontogenic cysts included 69.3% radicular, 20.3% dentigerous, 5.2% keratinizing odontogenic, 3.3% residual, and 1.9% other cysts, such as lateral periodontal, botryoid odontogenic, and gingival cysts. The most frequent clinical manifestation was swelling, followed by a combination of pain and swelling. Age, gender, and location were related to the etiopathologic characteristics of the cyst type. A definitive diagnosis can be made on the basis of clinical, radiological, and histological findings, which makes a good interdepartmental relationship between the clinicians and pathologists essential. Knowledge of the biological and histological behavior of the odontogenic cysts is required for their early detection and treatment.

Conservative management of dentigerous cyst in a child

“…The DC is the second most common odontogenic cyst in adults and the most common in children [15]. The study of Selvamani et al [1] determined the prevalence of odontogenic cysts in a South Indian sample population and found that the DC was the second more frequent cyst, after the periapical or radicular cyst. The majority of cases were reported in the second decade of life and they were more commonly seen in the anterior maxilla of males associated with erupted, developing, or impacted tooth.…”

“…Odontogenic cysts are frequently seen in dental practice and constitute an important group of oral and maxillofacial pathology [1]. However, the frequency of odontogenic cysts in children is relatively low [2].…”

“…However, despite their benign biological behavior, these lesions can reach a marked size if they are not diagnosed and treated appropriately [3]. Therefore, the correct diagnosis is essential for prompt and appropriate surgical treatment with adequate follow-up [1].…”

“…Buccal bony expansion is the most common clinical feature [5] related to epithelial proliferation, release of boneresorbing factors and an increase in cyst fluid osmolality [6]. It is the second most common odontogenic cyst, with a frequency ranging from 11.4% to 44% and is more frequently seen in the second decade of life [1]. Few of these cysts have been reported in children younger than 15 years of age [7][8][9][10].…”

“…The most commonly affected teeth are the mandibular third molar and maxillary canine, being rarely associated with other teeth [12]. The frequency of DC at these sites can be explained by the fact that the lower third molars and upper canines are the most commonly impacted teeth [1].…”
