Abstract
OBJECTIVE The study aimed to assess the usefulness of a bovine bone substitute material in treating cystic lesions in the jaw with a maximum diameter of <4 cm. MATERIAL AND METHODS In this prospective, randomized, single-blind intervention study of 116 patients, 61 underwent cystectomy with a subsequent filling of the defect using a bovine xenograft, and 55 underwent cystectomy alone. Volumetric measurement of the cysts was performed preoperatively and 6 and 12 months postoperatively using the available digital volume tomography data sets. Follow-up appointments were made 14 days and 1, 3, 6, and 12 months postoperatively. RESULTS Almost complete regeneration was seen in both treatment groups within 12 months, with no significant difference in absolute volume loss between the 2 groups (P = .521). Examination 14 days after surgery revealed a tendency for more wound healing disorders with the use of a bone substitute (P = .077). It was no longer possible to detect any further differences in later examinations. CONCLUSION Using bovine bone substitute material has no radiologically measurable advantage over cystectomy alone without defect filling regarding bone regeneration. In addition, there was a tendency for more wound-healing disorders to occur in the bone substitute group.

Abstract
PURPOSE This study was conducted in order to gain insight in the actual ratio of odontogenic keratocysts occurring in the tooth-bearing area as compared to the posterior region of the jaws in order to come up with reliable data to base upon a rational treatment policy. METHODS We searched MEDLINE, Web of Science, Scopus, and Cochrane databases for studies reporting on the location of mandibular and maxillary odontogenic keratocysts. All records were independently assessed and a meta-analysis was performed. Risk difference with a confidence interval of 95% of having the lesion in the posterior region versus the tooth-bearing area was the effect measure. P value for the summary effect of < 0.05 was considered statistically significant. RESULTS The 2615 records retrieved were reduced to 34 studies to be qualitatively/quantitatively assessed. The pooled values showed that the difference in the clinical risk of having keratocysts in the posterior region of the mandible and in the tooth-bearing area of the maxilla is 21 and 43%, respectively (P < 0.02 and P < 0.00001). CONCLUSIONS A substantial amount of keratocysts occur in the tooth-bearing area of the jaws, requiring attention.

Clin Pract 2019; 9:1132.

Abstract
The aim of this article is to describe a large mandibular cyst treated with decompression followed by surgical enucleation. Furthermore, we described the utility of cyst volume measurements by using a 3D reconstruction on Cone Beam Computed Tomography (CBCT). The dentigerous cyst is the most common cyst type of epithelial origin, arising from remnants of odontogenic epithelium, asymptomatic and associated with the crown of an unerupted or partially or completely impacted tooth. However, after a long duration and extension of the cyst volume it may provoke significant bone resorption, cortical expansion, tooth displacement and the vitality of neighboring teeth may be affected. The regular treatment of this lesion is enucleation and extraction of the involved tooth. Marsupialization and decompression are proposed when the volume of the cyst is well developed to release the cystic pressure and allow the bone cavity to progressively decrease in volume with the gradual apposition of bone. This report presents a large dentigerous cyst related to impacted mandibular third molar of a 21-year-old male patient. The cyst was treated successfully by decompression and later by surgical enucleation with surgical extraction of the related molar. In conclusion, the combination of decompression and surgical approach showed on the three-dimensional CBCT investigation a significant correlation between the treatment and volume reduction of the cyst. The clinical case described allows us to observe bone formation after decompression and surgical enucleation was performed with less risk on vital anatomic elements.

Abstract
Objective: The purpose of this retrospective study was to analyze clinic and radiologic features and the prevalence of jaw cysts in southeast region of Turkey. Materials and Methods: This study was carried out in 149 cysts of the jaw diagnosed among 407 individuals who were taken biopsy in our department from October 2008 to December 2012. All cysts were treated by enucleation, marsupialization, or combination, and all cases were histologically examined. Results: One-hundred-and-forty-eight cases were classified odontogenic, one was non-odontogenic. There were 89 cysts (59.7%) in men, 60 (40.3%) in women. The mean age was 32.72 years. We found 80 cysts (35 F, 45 M) in the maxillary and 69 (28 F, 41 M) in mandible. It is observed that 94 were radicular cysts (63%), 40 were dentigerous cysts (26.9%), 9 were odontogenic keratocysts (OKC) (6.1%), 5 were residual radicular cysts (3.4%), and 1 was nasopalatine cyst (0.6%). In radicular cysts, 56 of them (59.5%) were located in the anterior region of the jaws; 18 dentigerous cysts and 2 OKCs were found in the posterior region of mandible. Clinically, the chief complaint of patients was expansion and pain. Radiographically, scalloping of the lesion between the teeth was found in 1 case, root resorption was seen in 3 cases, and displacement of the teeth and follicles was observed in 16 cases. Conclusions: We found similar prevalence of jaw cysts that reported in the literature, in which most odontogenic cysts (OCs) were inflammatory origin.

Abstract
BACKGROUND Dentigerous cyst (DC) is one of the most common developmental odontogenic cysts. This hospital-based retrospective study evaluated the clinical and histopathological features of 338 DCs in Taiwanese patients. METHODS In this study, 338 consecutive cases of DCs were collected from January 1995 to December 2009. The demographic data and clinicopathological features of these DC cases were reviewed and analyzed. RESULTS The 338 DCs were taken from 332 patients (212 men and 120 women, mean age 33.0 years, range 5-83 years). There was a significant difference in the mean age between male and female patients (P < 0.05). Of the 338 DCs, 122 were found in the maxilla and 216 in the mandible. The most common site for DCs was the mandibular molar region (169 cases) and the most frequently involved tooth was the mandibular third molar (153 cases). Forty-six of the 338 DCs were found to be associated with supernumerary teeth. Microscopically, 317 cysts were lined by stratified squamous epithelium, 9 by mucoepidermoid-typed epithelium, and 12 by ciliated pseudostratified columnar epithelium. Hyaline bodies of Rushton, odontogenic epithelial rests, cholesterol clefts, foamy histiocytes, hemosiderin-laden macrophages, and dystrophic calcifications were discovered in 11, 78, 90, 33, 62 and 45 DCs, respectively. CONCLUSION Our results indicate that DCs of Taiwanese patients have a male predominance and occur more frequently in patients between 10 and 29 years of age. The most commonly affected site for DCs is the mandibular molar region and the most frequently involved tooth is the mandibular third molar.

Abstract
To thoroughly understand the biology of any lesion and render the appropriate management, clear and accurate definitions are paramount. For benign cysts and tumors of the oral maxillofacial region, an accurate depiction of these lesions needs to be elucidated to provide both the treating surgeon and the patient with a clear understanding of the course of treatment and the outcome.

Abstract
Background: The objective of this study was to perform a cumulative analysis of odontogenic cysts obtained from the data of major dental institutions of Bangalore city, as well as to evaluate their distribution during a 5-year period and compare the results with other international studies. Materials and Methods: Data for the study were obtained from the reports of patients diagnosed with odontogenic cysts between 2005 and 2010 from different dental institutions of Bangalore. Case records of patients that fit the histological classification of the World Health Organization (WHO) (2005) were included in the study and the following variables were analyzed: age, gender, anatomic location, and histological type. Results: In a total of 252 cyst specimens diagnosed, 79.76% were odontogenic cysts and 20.24% were nonodontogenic cysts. Among the odontogenic cysts most frequent lesions were radicular cysts (50.25%), followed by keratocysts (27.36%) and dentigerous cysts (22.39%). Conclusions: Our study provides a cumulative data of odontogenic cysts in the population of Bangalore city. The results of our study showed a similar frequency of odontogenic cysts as compared to other populations of the world, with radicular cyst being identified as the most frequent odontogenic cyst. Keratocyst was the second most common cyst followed by dentigerous cyst.

Abstract
OBJECTIVES The aim of this review is to evaluate the principal clinical and conventional radiographic features of non-syndromic keratocystic odontogenic tumour (KCOT) by systematic review (SR), and to compare the frequencies between four global groups. METHODS The databases searched were the PubMed interface of Medline and LILACS. Only those reports of KCOTs that occurred in a series of consecutive cases, in the reporting authors' caseload, were considered. RESULTS 51 reports, of 49 series of cases, were included in the SR. 11 SR-included series were in languages other than English. KCOTs affected males more frequently and were three times more prevalent in the mandible. Although the mean age at first presentation was 37 years, the largest proportion of cases first presented in the third decade. The main symptom was swelling. Over a third were found incidentally. Nearly two-thirds displayed buccolingual expansion. Over a quarter of cases recurred. Only a quarter of all SR-included reported series of cases included details of at least one radiological feature. The East Asian global group presented significantly as well-defined, even corticated, multilocular radiolucencies with buccolingual expansion. The KCOTs affecting the Western global group significantly displayed an association with unerupted teeth. CONCLUSIONS Long-term follow-up of large series that would have revealed detailed radiographic description and long-term outcomes of non-syndromic KCOT was lacking.

Abstract
OBJECTIVE The present study aimed to evaluate the prevalence, sex predilection and treatment modalities of OKC in Central India. MATERIALS AND METHODS Total 2900 patients were screened from various hospitals and centers. Age of patients and site of lesion was recorded. OKC was classified into initial, moderate and advanced depending on the radiological involvement and treatment modalities given with respect to the extent of the OKC. RESULT Total 49 patients were diagnosed with the presence of OKC. It was found that mostly it is common in 3rd and 4th decades, with the mean age 28 years in males and 31 years in females. The most common site of occurrence was angle of mandible and the ramus region. The treatment of OKC, on the basis of the radiographic classification, gives excellent results with minimum recurrences. CONCLUSION The most common age and site occurrence was relevant with that of previous studies (Browne, Br Dent J 128(5):225-231, 1970, Chen and Lin, Gaoxiong Yi Xue Ke Xue Za Zhi 2(9):601-607, 1986). This study concluded by considering multicentric incidence, prevalence of OKC in Central India, that the population should be screened for OKC. The screening should be done by clinical, radiological and histopathological. While screening all the parameters should be considered to diagnose and treat the patients for the prevention of morbidity.

Abstract
OBJECTIVE To determine the demographic profile of all histologically diagnosed odontogenic cysts (OC) and nonodontogenic cysts (nOC) over a 51-year period in the Brazilian population. STUDY DESIGN Case records of patients with OC and nOC from the files of the Oral Pathology Service, School of Dentistry, Federal University of Minas Gerais, Belo Horizonte, Brazil, during the period of 1953-2003 were evaluated. RESULTS Among 19,064 oral biopsies, 2,905 (15.2%) presented criteria of OC and nOC. Of these, 2,812 specimens (14.7%) were diagnosed as OC and 93 (0.5%) represented nOC. The 3 most frequent OC diagnosed were radicular cyst (61.0%), dentigerous cyst (25.3%), and odontogenic keratocyst (7.2%). The most frequent nOC was the nasopalatine duct cyst (2.2%). CONCLUSION Our results demonstrate that there is a wide range of OC and nOC, with some cysts having a predilection for age, gender, and localization. We also showed demographic aspects and clinical characteristics of these cysts. These could be used as baseline data to obtain more epidemiologic information about the OC and the nOC especially in the Brazilian population.

Abstract
The aim of this study was to analyze the files of 695 consecutive patients operated on under general anesthesia for odontogenic cysts in an adult French teaching hospital for comparison with findings in world surveys. A retrospective survey of cysts of the jaws was undertaken at the Maxillofacial department, Pitié-Salpêtrière University Hospital, Paris, France. Data were retrieved from case notes, imaging, histopathology records and follow-up reports from January 1995 to January 2005. The mean age of patients was 41.8 +/- 15.8 years. There was an overall male to female ratio of 1.86:1. Mandible to maxilla ratio was 3:1. Regarding the mandible, the angle was involved in 36% of the cases, horizontal branch in 32%, parasymphysis in 18%, ramus in 11.6%, coronoid process in 1.5% and condyle in 0.9% (total = 100%). Regarding the maxilla, the canine to canine region was involved in 40% of the cases, premolar and molar region in 45%, and wisdom tooth region in 15% (total = 100%). The three most frequently diagnosed odontogenic cysts were radicular cysts (53.5%), dentigerous cysts (22.3%) and odontogenic keratocysts (19.1%). Together, these three entities represented 94.9% of all odontogenic cysts. The mean number of operation per patient was 1.16 (SD: 0.6, range: 1-10). The mean cumulated duration of hospitalization for one patient was 2.46 days (SD: 1.9, range: 1-28). The mean length of follow-up was 8.4 months (SD: 15.2, range: 0-120). Sixty five percent had a follow-up inferior to 6 months and 18% had no follow-up at all. The two most important findings of this case series are 1) the important number of radicular cysts that could be avoided because most of these cysts develop as a consequence of advanced carious lesions and 2) regarding other types of cysts, the dramatic rate of patients lost to follow-up.

Abstract
BACKGROUND The aim of this study was to determine the range of all histologically diagnosed odontogenic cysts along with age range, sex distribution and site of presentation over a 30-year period. METHODS All entries for odontogenic cysts occurring during 1975-2004 inclusive were retrieved and analysed for demographic data. RESULTS A total of 55,446 specimens were received, of these 7121 (12.8%) specimens were diagnosed as odontogenic cysts. Radicular cyst was the most common diagnosis (52.3%), followed by dentigerous cyst (18.1) and odontogenic keratocysts (11.6%). CONCLUSIONS Our study provides demographic data on a large series of odontogenic cysts in a European population. This is one of the largest series reported to date. Cysts such as the paradental cyst have a predilection for certain ages, sexes and sites. Odontogenic keratocysts and glandular odontogenic cysts have a marked propensity to recur as well as behave aggressively. It is essential that such lesions are detected as early as possible to minimize any necessary surgery.

Abstract
The maxillofacial region is affected by a greater number of cysts than any other part of the body. In this study, 90 odontogenic cysts were collected from 90 patients over a five-year period. Patients with radicular cysts, dentigerous cysts and odontogenic keratocysts were further analyzed with regard to age, sex and anatomical distribution. Using the histological classification of the World Health Organization, 53 cases (59%) were classified as radicular cysts, 24 (27%) as keratocysts and 13 (14%) as dentigerous cysts. Radicular cysts occurred most frequently in the anterior region of the maxilla, odontogenic keratocysts in the ramus and angular region of the mandible, and dentigerous cysts in the mandible. No recurrences were observed during the limited follow-up period.

Abstract
The mandible may be affected by a variety of pathological conditions such as ameloblastomas, odontogenic keratocysts, central giant cell granulomas, fibro-osseous lesions, and osteomas. They generally are benign, and conservative treatment can be enough in most of the cases. However, they can be clinically aggressive, and especially ameloblastomas, odontogenic keratocysts, and fibro-osseous lesions are prone to recur. The method of treatment remains a matter of controversy in these cases. The aim of this analysis was to study 100 patients who had been treated for benign mandibular lesions, and to emphasize the importance of free fibula flap in the treatment of such lesions.

Abstract
OBJECTIVE Histopathological and lectin-histochemical characteristics were studied in the lining epithelium of postoperative maxillary cysts (POMC). MATERIALS AND METHODS Histological (HE, PAS, AB), immunohistochemical (CD3 and L26) and lectin (wheat germ agglutinin, WGA; Ulex europaeus agglutinin I, UEA-I; concanavalin A, ConA) stainings were performed in the 360 POMC specimens. The number of goblet cells and inflammatory cells was counted and statistically analyzed. RESULTS The lining epithelium was classified into three types based on histopathological characteristics; pseudostratified ciliated epithelium (pSCE), transitional epithelium (TE) and stratified squamous epithelium (SSE). Local infiltration of inflammatory cells into the cyst wall was associated with an increased number of goblet cells in the lining epithelium. The observed association between the infiltration of inflammatory cells and an increase in the number of goblet cells was statistically significant in groups with lining pSCE and TE. Glycoconjugate histochemical analysis revealed that the surfaces of the lining epithelium with squamous metaplasia showed an increased degree of staining reactivity with UEA-I, whereas the staining reactivity with ConA was reduced. Goblet cells were able to be stained with WGA and UEA-I, but showed extremely low reactivity with ConA. CONCLUSION Changes in the glycoconjugate expression of the metaplastic lining epithelium and goblet cell development play an important role in the local defense mechanisms against inflammatory factors in POMC.

Abstract
A unilocular follicular or dentigerous cyst (FDC) with a diameter of 12 mm was observed incidentally in the premaxilla of a midsagittal section of the head of a 65-year-old cadaver. The mucosal lining of the cyst was grey in color and granular in texture: the osseous walls had a thickness of less than 1 mm. In the floor of the cyst, a slender, fully developed incisor tooth was fixed in a horizontal position. The alveolar processes of the maxilla and mandible were completely edentulous. Postmortem computer tomography showed the cyst in an osteolytic lesion of the premaxilla, and histology revealed a lining of non-keratinized stratified squamous epithelium supported by a lamina propria of dense connective tissue.

Abstract
AIM The purpose of this study was to outline the radiographic appearance of radiolucent lesions related to the molar teeth and to determine which features indicate aggressive lesions. PATIENTS AND METHODS Panoramic radiographs were reviewed in 66 patients with radiolucencies related to the molar teeth. The radiographic appearances of the lesions were assessed with regard to location and size, and the relationship to the molar teeth. Radiographic evidence of aggression was assessed and pathology reviewed. RESULTS Nineteen patients had aggressive and 47 had non-aggressive radiolucent lesions. The aggressive lesions included keratocysts, unicystic ameloblastoma, adenoid cystic carcinoma, giant cell granuloma, myxofibroma, chondroblastic osteosarcoma, mestastases and squamous cell carcinoma of the tongue invading the mandible. CONCLUSION The differential diagnosis of radiolucent lesions in the mandible can be difficult using panoramic radiographs alone. Helpful features in determining aggression were older patients, larger lesions, Lodwick type IC tumour border, condition of the mandibular cortex, movement of adjacent teeth and the relationship of the inferior alveolar canal.
