Prevalence Of Odontogenic Cysts Research Articles

Prevalence, Characteristics and Distribution of Odontogenic Cysts amongst the Indian Subpopulation of Southern Rajasthan: A 5-year Retrospective Study of 218 Cysts.

Odontogenic cysts (OCs) arise from the odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Proliferation and/or degeneration of this epithelium lead to OC development. The purpose of this study was to determine the prevalence, characteristics, distribution and clinicopathological features of OCs and compare with other studies. Records of OCs were retrieved, and patient's data, aetiology, clinical features, histopathological distribution, treatment, complications and recurrence were studied. A total of 218 OCs were studied in 200 patients. The mean age of patients was 35.74 years. The overall sex ratio (male: female) was 1.22:1. Second, third and fourth decades of life were commonly affected. The majority of the patients (85%) reported with a complaint of pain (with or without swelling). Radicular cyst was the most prevalent type (49.55%). The most common site involved was the anterior maxilla (41.75%). Dental complications such as displacement, mobility, discoloration and root resorption were diagnosed in 91 cysts (41.75%). Bony complications such as expansion and perforation were present in 136 cysts (62.38%). Dentition was non-vital in 61.46% of cysts. The most common treatment method performed was combination surgery (enucleation with or without endodontic treatment/extraction and apicoectomy). Recurrence rate was 3.20%. The prevalence, characteristics and distribution features of OCs in India are similar to those of studies conducted in other parts of the world. There is a broad spectrum of OCs, with some cysts having a propensity for certain age, gender and site, whereas a few cysts have distinct properties to recur and have aggressive and invasive behaviour.

Cystic Lesions and Odontogenic Tumors in Older People: A Brazilian Multicenter Study.

Some odontogenic cysts (OCs) and odontogenic tumors (OTs) are infiltrative and often recur, causing bone destruction and tooth loss. In the elderly, in particular, these injuries cause significant morbidity, making rehabilitation difficult and compromising the quality of life of these individuals. Objective: To determine the prevalence and demographic characteristics of OCs, non-odontogenic cysts (NOCs), and OTs diagnosed in an elderly Brazilian population (≥60 years). A retrospective descriptive cross-sectional study was carried out in three Brazilian pathology referral centers (1999-2019). Data regarding age, sex, ethnicity, anatomical location, symptomatology, and histopathological diagnosis were obtained from histopathological records and analyzed. Pearson's Chi-squared and Fisher's exact tests were used to evaluate the association between the different groups of oral lesions and demographic findings, adopting a P-value of ≤ 0.05 and a 95% confidence interval. A total of 7,476 histopathological records were evaluated, of which 389 (5.2%) cases were classified as OCs, 86 (1.15%) as NOCs, and 83 (1.11%) as OTs. The most common lesions in each group were periapical cysts (n=166; 68.9%), ameloblastomas (n=65; 77.4%), and salivary duct cysts (n=45; 52.3%). Overall, males were slightly more affected (n=279, 50.2%). Most individuals were between 60 and 69 years (n=358; 64.2%). OCs and OTs preferentially affected the mandible (n=280; 62.2%). NOCs occurred more frequently in the lips (n=19; 22.1%), followed by buccal mucosa (n=18; 20.9%). The overall concordance between clinical and histopathologic diagnoses was 47.2% (213 of 451 cases). OCs were relatively common, whereas NOCs and OTs were rarer among the elderly. The low concordance between clinical and histopathological diagnosis highlights the importance of histopathological analysis to ensure an accurate diagnosis. Dentists and geriatricians must be familiar with these lesions to ensure an early diagnosis, reduce morbidity and improve the quality of life of these individuals.

Prevalence of odontogenic cysts in a group of Libyan population: A retrospective study.

Odontogenic cysts (OCs) are commonly encountered lesions affecting the human jaws having special clinical and radiographic features depending on cyst type. The aim of this study was to determine the prevalence of odontogenic jaw cysts in a Libyan population in Benghazi and to compare these data with previously published reports from Libyan and other geographic areas. This is a descriptive study where screening of 2189 biopsies (retrieved from the archives of The Department of Oral Pathology/University of Benghazi, Libya) was performed for the sake of recognizing the three cysts chosen for the purpose of this study. : Out of the screened lesions, 276 cases (12.6%) were diagnosed as odontogenic cysts in the period from 2006 to 2019. Of those, 67.39% were inflammatory and 32.61% were developmental in nature. Radicular cysts (60.5%) were the most frequent cysts followed by dentigerous cysts (14.8%) and keratocysts (14.5%). The mean ages of the patients were 32.3, 29.7, and 33.2 years, respectively. Occurrence of the cysts was noticed more in the maxilla than in the mandible (1.3:1). The overall male-to-female ratio was 1.1:1. The prevalence of odontogenic cysts was similar to that reported in a previous study in Libya and other countries irrespective to WHO (2017) classification of odontogenic cysts.

Prevalence of odontogenic cysts in oral and maxillofacial surgery department of hasan sadikin general hospital: 2 years retrospective study

Background: Odontogenic cysts are cysts arising from the odontogenic epithelium. According to the World Health Organization in 2017, classification of odontogenic cysts are classified into cysts originating from inflammatory and developmental processes. Most cystic lesions of the oral and maxillofacial cavity are of odontogenic origin and have higher incidence than other body parts. This study to explain about prevalence of odontogenic cyst in RSUP Hasan Sadikin in 2019-2020 .Method: This study was a retrospective study that included 30 patients diagnosed with odontogenic cysts during 2019-2020.

Conclusion: The radicular cyst is most common cyst of oral cavity while adult gingival cyst is least common cyst. Keywords: Cyst, Jaw bone, Prevalence, Odontogenic, Nonodontogenic.

Prevalence of odontogenic cysts and its associated factors in South Indian population.

Background:Odontogenic cysts (OCs) constitute a major part of oral pathological lesions, but little is known about their distribution patterns in various populations.Aims:The aim was to determine the prevalence and factors associated with the cases of histopathologically diagnosed OCs that report to our institution and to analyze the factors associated with the presence of OCs and to study the biologic behavior of different types of cysts.Materials and Methods:A cross-sectional study was performed on 596 oral and maxillofacial specimens during 2013–2017. Out of these, the cases which were histopathologically proven as OCs were separated and data were collected and analyzed regarding the age, gender, primary symptom, site, radiographic feature, histopathologic diagnosis, treatment given, recurrences and associated conditions if any.Results:Of the 596 cases included in the study, 67 (11.2%) had a histopathological diagnosis of OCs. 41 cases were inflammatory cysts and 26 developmental cysts. 28 cases (41.8%) were reported as periapical cysts, 10 cases (14.9%) were odontogenic keratocysts (OKCs), 9 cases (13.4%) were dentigerous cysts, 8 cases (11.9%) were inflamed cyst wall, 5 cases (7.5%) each of residual cyst and developmental OCs and one case (1.5%) each of orthokeratinized OC and calcifying OC.Conclusion:This study showed that the prevalence of OCs was similar to other reported studies. Periapical cysts were the most common cysts reported, followed by OKCs showing that the latter were more frequent than dentigerous cysts.

Comparative analysis between developmental and inflammatory odontogenic cysts: retrospective study and literature review.

To assess epidemiological, clinical, and radiographic characteristics of odontogenic cysts (OCs) in a South Brazilian sample and to compare the results with international literature. For the main study purposes, biopsy and histopathological records were retrospectively analyzed from December 2006 to December 2018, OC cases were selected, and data about clinical characteristics were evaluated. Further, a literature review was performed for similar studies. In the main study, the prevalence of OCs was 11.26% (n = 406), the majority of patients was male (56.73%), and the mean age was 39 ± 17.33 years. Radicular cyst was the most common OC (46.06%), followed by the odontogenic keratocyst (15.02%), dentigerous cyst (14.04%), and paradental cyst (13.55%). Inflammatory OCs were more prevalent in the maxilla (54.84%) and developmental cysts in the mandible (69.92%) (p < 0.05). Individuals with inflammatory OCs were usually older (41.0 ± 15.34 years) than the ones with developmental OC (28.0 ± 19.68 years) (p < 0.05). Regarding the literature review, 22 articles were included. Analysis of pooled data showed that global prevalence of OCs was 11.62% (95%CI = 9.97-13.37), from which radicular cyst was the most common (54.26%; 95%CI = 49.30-59.18), followed by dentigerous cyst (22.94%; 95%CI = 19.22-26.89) and odontogenic keratocyst (11.99%; 95%CI = 8.88-15.49). Furthermore, studies from Asia (72.40%; 95%CI = 70.30-74.40) and South America (68.48%; 95%CI = 64.07-72.72) presented the highest frequencies of inflammatory OCs. The main study showed that the prevalence of OCs was 11.26%, which corroborates with international literature. Considering geographic variability of OC distribution, public health authorities and researchers could use these data for the development of focused prevention interventions, especially with regard to inflammatory OCs.

Ponte Academic JournalJun 2018, Volume 74, Issue 6 CLINICAL AND HISTOPATHOLOGICAL EVALUATION OF ODONTOGENIC CYSTS ACCORDING TO WORLD HEALTH ORGANIZATION NEW CLASSIFICATION OF ODONTOGENIC CYSTS: A PRELIMINARY STUDY Author(s): Onur Şahin ,Onur OdabaşıJ. Ponte - Jun 2018 - Volume 74 - Issue 6 doi: 10.21506/j.ponte.2018.6.5 Abstract:Background: Having knowledge about the frequency and distribution of cysts helps to know the possible diagnosis and complications of cysts and to plan appropriate treatment. There are many studies on the prevalence of odontogenic cysts in literature. However, these studies are based on the WHO classifications of 1992 and 2005, and there is no study using the latest classification updated in 2017. In this study, the latest classification scheme of WHO in 2017 is used. Methodology: Data were collected from the medical records of the 462 odontogenic cyst patients regarding age, gender, follow-up duration, systemic conditions, localization of the cysts, examination findings before the operation, treatment methods applied, provisional diagnosis and pathology report. Cystic lesions were classified according to the new WHO classification in 2017. Results: Pathology reports showed 246 patients had (53.2%) radicular cyst, 3 patients (0.6%) had inflammatory collateral cyst, 78 patients (16.8%) had dentigerous cyst, 51 patients (11.1%) had odontogenic keratocyst, 12 patients (2%) had lateral peridontal cyst, 15 patients (3.2%) had gingival cyst, 18 patients (3.8%) had glandular odontogenic cyst, 9 patients (1.9%) had calcifying odontogenic cyst , 6 patients (1.2%) had orthokeratinized odontogenic cyst and 24 patients (5.2%) had nasopalatine duct cyst. Conclusion: Radicular cyst,dentigerous cyst and odontogenic keratocyst are the most prevalent odontogenic cyst in this study. The future studies might include more participants to evaluate for odontogenic cysts prevalence, odontogenic and non-odontogenic tumours, malign tumours, and precancerous lesions in oral cavity using the WHO classification scheme updated in 2017.

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.

Prevalence profile of odontogenic cysts and tumors on Brazilian sample after the reclassification of odontogenic keratocyst

PurposeThe aim of this study was to evaluate the impact of the reclassification of odontogenic keratocyst (OKC) as a tumor on the prevalence profile of odontogenic cysts (OCs) and odontogenic tumors (OTs). Study designTwo referral Oral and Maxillofacial Pathology services in Brazil were evaluated. All cases diagnosed as OCs or OTs were selected and classified according to the 1992 WHO-classification (cases before 2005 WHO classification of tumors excluding OKC) and the 2005 WHO classification of tumors, going forward including cases of odontogenic keratocyst tumor (KCOT). The frequency and prevalence of OCs and OTs were compared before and after the reclassification. ResultsAmong 27,854 oral biopsies, 4920 (17.66%) were OCs and 992 (3.56%) were OTs. The prevalence of OTs before 2005 WHO classification of tumors was 2.04%, while the prevalence after 2005 WHO classification was 11.51% (p < 0.0001). Before 2006, the most frequent tumor diagnosed was odontoma with 194 cases (39.67%), and after 2005 WHO classification of tumors the KCOT was the most frequent with 207 cases (41.07%). ConclusionsThe increase in the prevalence of OTs after 2005 WHO is related to the improvement of pathology services and to the inclusion of KCOT in the OTs group.

Perfil epidemiológico de pacientes com diagnóstico de quisto odontogénico em uma universidade de odontologia

ObjectiveThis study aimed to investigate the epidemiological profile of diagnosed odontogenic cysts (OCs) in patients of a private dentistry university over an 8‐year period. MethodsWe retrospectively analyzed the following characteristics from the histopathological records of patients: gender, age, anatomic location, type of cyst, and patient history. ResultsWe identified a total of 158 cases, showing a female predominance (50.6%), largely affecting patients younger than 60 years (88.6%), and with a lesion evolution time of ≥6 months (17.7%). The maxilla was the most prevalent anatomic location for OCs (47.5%). Further, of the 158 OC cases, 58 (36.7%) were developmental OCs and 100 (63.3%) were inflammatory OCs. The most prevalent types of OCs were apical periodontal cysts (57%) and dentigerous cysts (34.8%). Thus, our results have highlighted a higher prevalence of inflammatory OCs occurring in the maxilla, predominantly affecting female patients younger than 60 years. ConclusionThe epidemiological profile of OCs observed in this study was similar to that observed in different populations, with a discrete predominance of females and discrepancies regarding anatomic location.

Prevalence of odontogenic cysts and tumors: A retrospective clinico-pathological study of 204 cases

Background: The purpose of this study was to determine the prevalence of odontogenic cysts (OCs) and tumors over a period of 5 years and 5 months and to compare with other national and international studies. Materials and Methods: Data for the study were obtained from the reports of patients diagnosed with OCs and tumors between 2007 and 2012.

Results: Out of the 809 biopsy reports analyzed, we found 100 cases of odontogenic cysts (12.36%).The mean patient age of the appearance of the lesion was 42 years (range 8-75). The cysts were slightly more prevalent in females (52%). The lesion size ranged from 5-60 mm; with a mean size of 18mm.Unilocular lesions were more common than the multilocular lesions. The most common location of the odontogenic cysts was in the maxilla (n=59) than mandible. (n=41) The most frequent diagnosis was radicular cyst (n=52). Odontogenic keratocysts constituted 20 cases (20%), 19 cases (19%) were dentigerous cysts and 9 cases (9%) were residual cysts. Conclusions: The most frequently occurring lesion was radicular cyst and the site was the anterior region of the maxilla. The keratocystic odontogenic tumor (KOT) and dentigerous cyst were the next most common lesions and the preferred site was in the ramus and angular region of

Odontogenic Cysts: Analysis of 680 Cases in Brazil

The purpose of this study was to evaluate the prevalence of 680 odontogenic cysts diagnosed in Porto Alegre, RS, Brazil, and to compare results with findings in the literature. Data of odontogenic cysts diagnosed from 1985 to 2005 were collected from the files of the Oral Pathology Laboratory of Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, RS, Brazil, and entered in a standardized form for later comparisons. The most prevalent odontogenic cysts were radicular (72.50%), dentigerous (22.20%) and residual (4.26%) cysts. The mandible of white patients was the anatomic site and ethnic group most frequently affected by this disease. Four of the six types of cysts were more frequent in the second and fourth decades of life, and no significant differences were found between sexes in the diagnosis of odontogenic cysts. In conclusion, the prevalence of odontogenic cysts was similar to that reported in the literature, which shows that inflammatory cysts are the most frequent.
