BACKGROUND Most common osseous destructive lesions effecting the jawbone are odontogenic cystic lesions, which are lined by epithelium, has been involved in the formation of teeth as the epithelial cell rest are present in jawbone after teeth formation. The three most common odontogenic cysts (OCs) are radicular cyst (RC), dentigerous cyst (DC) and the odontogenic keratocyst (OKC). Less common variety is the residual cyst. Odontogenic cysts are mainly developmental and inflammatory in origin. The objective of the present study was to find clinico-radiographic characteristics of odontogenic cysts in the mandible. METHODS This was a case series (descriptive) study on OCs of mandible conducted at Tripura Medical College and Dr BRAM Teaching Hospital, Hapania, Agartala, Tripura (W), India, over a period of 6 months from August 2019 to January 2020. Subjects showing clinico-radiographic features of OCs in mandible were included, subsequently confirmed by histopathological examinations. Usually orthopantomograms (OPGs) and intra oral peri apical radiograph (IOPAs) were done for radiological findings, computed tomography (CT) scan was required for examination of the size of lesion. Data were analysed using windows excel. RESULTS Diagnosis of OCs was confirmed in 20 patients, among them, males were (60 %) and female were (40 %). The age range of the patients was 17 - 65 years. Most common type of cyst diagnosed in the study was radicular cyst in 50 % cases followed by dentigerous cysts which were in 30 % cases, odontogenic keratocysts were in 15 % patients and others were 5 %. RCs were represented in higher percentage (50 %). Right side of mandible was the most effected side (60 %) than left side (40 %). Main finding of the study was, in every type of cystic lesions, males were recorded as predominant, and it occurred in early age group. CONCLUSIONS Main finding of the study was radicular cyst which was in higher percentage (50 %) and was being most common with association of carious tooth.

CDC7 is a serine/threonine kinase which has an essential role in initiation of DNA proliferation and S phase. It increases the invasion and proliferation in many pathologic lesions. This study aimed to evaluate the expression of CDC7 in the most common odontogenic cysts. We evaluated 17 dentigerous cysts, 18 odontogenic keratocysts (OKC) and 13 radicular cysts immunohistochemically. The mean expression of CDC7 was analyzed using ANOVA and Post-HOC methods. All specimens revealed CDC7 expression. Higher expression of CDC7 in OKC and radicular cyst was shown in comparison to dentigerous cyst (P < 0.001), while radicular cyst and OKC groups showed no difference in CDC7 expression (P = 0.738). The high expression of CDC7 in OKC suggests that this protein could be related to the higher proliferation rate and invasiveness of OKC. On the other hand, the higher CDC7 expression in radicular cyst may simply be related to inflammation as this cyst is neither aggressive nor invasive.

Background: Odontogenic cysts are the most common form of cystic lesions affecting the maxillofacial region and one of the main causes of the damage of these bones.Objective: To determine the frequency of different types of odontogenic jaw cysts diagnose among the Bangladeshi population.Study design: A descriptive observational study was made of 62 patients.Study setting and period: The study was done in the Department of Oral & Maxillofacial Surgery, Bangabandhu Sheikh Mujib Medical University, Shahbag, Dhaka-1000 from 1st March’ 2010 to 28th February’2011.Participants: Sixty-two patients with cystic lesions in the maxillofacial region were selected for the study.Methods: Patients who attended in the Oral & Maxillofacial Surgery Department of BSMMU during the study period with suspective cystic lesion in the maxillofacial region were included in the study. After clinical diagnosis with odontogenic cysts all the patients were treated surgically either under local anesthesia or under general anesthesia if required. Cystic lining was then sent for histopathological confirmation. Data were collected from a total of 76 patients with a clinical diagnosis of odontogenic jaw cysts. Of those, data of 14 patients were not included in the analysis (Histopathology showed no cystic lesion in 6 patients and non odontogenic cyst in 8 patients). Therefore data of a total of 62 patients were analyzed for the purpose of the study. The study protocol was explained to the patients in detail before obtaining the informed consent from the patients. Patients were allocated for the study.Outcome Variable: The following variable were recorded: gender, age, site of the lesion, swelling, tooth mobility, carious tooth, discolored tooth, missing tooth, radiological features, impacted tooth and correlation with histological types.Results: Out of 76 histopathology reports analyzed, odontogenic cyst found in 62 cases (82%). The mean patient age was 28.06 years. The cysts were slightly more prevalent in females (52%). Radicular cyst was the most prevalent histological type (56%), followed by dentigerous cyst (21%), odontogenic keratocysts (15%) and residual cysts (8%). The most common location of the odontogenic cysts were in the maxilla (n=35) than mandible (n=27).Conclusion: The most frequently occurring lesion was radicular cyst and the site was the anterior region of the maxilla. The dentigerous cyst and odontogenic keratocyst were the next most common lesions and preferred site was in the ramus and angular region of the mandible.Update Dent. Coll. j: 2015; 5 (2): 30-39

Columnar Cells

Odontogenic cysts are typical diseases that account for the majority of lesions that occur in the jawbone, among which radicular and dentigerous cysts are the most common. In some cases, metaplastic changes in these cysts result in the development of goblet-like mucous cells admixed with ciliated columnar cells. Odontogenic cysts are of little importance to emergent risk in normal conditions, but such histological alterations could be drastic and even confusing. We examined the expression of MUC family in these cystic lesions and investigated their relationship with histomorphological features. 6 cases of radicular and dentigerous cysts with obvious metaplastic changes were studied. Of these, 4 were male and 2 were female. One case occurred in the maxilla and 5 in the mandible. Immunohistochemically, almost the entire epithelium was positive for MUC1 and MUC4 in all cases, and the decapitation-like protrusions on the surface layer showed stronger expression. MUC5AC was selectively expressed in mucous cells, while MUC2 and MUC6 were negative. The lining epithelium with metaplastic changes closely resembled the bronchial epithelium, and MUC expression indicates a potential role in these morphological changes.

Dentigerous cysts are the second most common odontogenic cysts of the mandible. They may vary in size from 2 cm to more than 10 cm. In the present report, a dentigerous cyst with massive involvement of the right half of the mandible in a young patient is presented. For cosmetic reasons and long term risks these cysts must be treated. Surgical removal is the preferred modality and a submandibular route should be chosen in large lesions. Bony cavities may be decreased in volume by using osteoperiosteal flaps, but there is no need for primary bone grafting, even for large defects.

Referral Practice

Medical records and radiographs were retrospectively reviewed over a 3-year period (2012-2015) from dogs presented to a private dental referral practice. Medical records were evaluated for the diagnosis of impacted or embedded teeth. The identified dogs’ radiographs were reviewed for the presence of radiographically significant cystic lesions that were associated with the impacted or embedded teeth. Radiographic criteria were established by the authors for the purposes of identifying cystic lesions in dogs of different breeds and sizes, using established indices from human dental pathology as a basis. When histopathology results were available, they were reviewed and reported. In this study, 136 dogs ranging in age from 3 months to 17 years were diagnosed with 213 unerupted teeth during the study period. There were 62 (29.1%) of the 213 radiographically apparent cystic lesions identified based on the criteria proposed in this study. In this study, 146 (68.5%) of the 213 unerupted teeth were identified as mandibular first premolar teeth. Histopathology was obtained on 28 (45.1%) of the 62 diagnosed cystic lesions. Dentigerous cysts accounted for 20 (71.4%) of the 28 cystic lesions. Brachycephalic breeds were overrepresented in this study. Boxer, pug, Shih Tzu, and Boston terrier dogs were most likely to present with cystic lesions associated with unerupted teeth. Seventeen (85%) of the 20 cases with a histopathologic diagnosis of dentigerous cyst were found within these 4 brachycephalic breeds.

Dentigerous cysts represent the second most common odontogenic cysts of the jaws after radicular cysts and are usually associated with the crowns of unerupted permanent teeth and rarely deciduous teeth. They are usually solitary in their presentation. Multiple and bilateral dentigerous cysts are an extremely rare presentation in the absence of developmental syndromes or systemic diseases or the use of prescribed certain medications. We hereby present a case of a bilateral dentigerous cyst of the maxilla in a 10-year-old child involving the crowns of unerupted permanent second premolar on the right side and the unerupted permanent canine on the left side. An effort has also been made to review the existing literature on this entity and to stress the importance of radiographic and histopathological examinations in diagnosing such an entity.

Dentigerous cysts are the second most common odontogenic cysts of the jaws, and sometimes inhibit the eruption of teeth. Almost all of the dentigerous cyst encloses the crown of an unerupted tooth and the radiolucent area is attached to the tooth at the cementoenamel junction. Dentigerous cyst is more common in male patients and most commonly develop in the second and third decades of life. Clinically, a localized swelling of the alveolar bone can be detected, however, dentigerous cysts can be asymptomatic during a long period of time, leading to a significant destruction of bone. The conventional treatment plan is cyst removal and marsupialization. Marsupialization therapy can be useful to promote the spontaneous eruption of the involved tooth within the cyst. However, tooth eruption does not always occur spontaneously after marsupialization. This article aims to report a clinical case of the diagnosis and treatment of a dentigerous cyst in the maxilla associated with an unerupted canine in a pediatric patient and discussion of the treatment performed.

Background: Impacted teeth are commonly asymptomatic and not associated with any pathologic lesions for years. Any change in the size of the follicle associated with impacted teeth may result in odontogenic cysts or tumors. CBCT plays an important role in determining the radiographic features of a lesion and therefore, is very helpful for accurate diagnosis and treatment planning. Objective: This study aims to evaluate radiolucent lesions associated with impacted teeth in terms of age and sex distribution, localization, and comparison with the pathological diagnosis. Method: In this retrospective study, out of 6758 CBCT images, 400 images revealing radiolucent lesions were detected. The study included only 190 cases (regarding 180 patients) which had a matching histopathological evaluation. Data related to the age and sex of the patients, localization of the lesions, and comparison of them with the pathological diagnosis were recorded and analyzed. Results: The most encountered lesions were dentigerous cysts (60%) and odontogenic keratocysts (26.3%). Males were most affected (63.3%). Most of the lesions were found in the left and right posterior mandible and mostly (66.8 %) associated with third molars. Out of 123 radiological diagnoses of dentigerous cyst cases, histopathological diagnoses confirmed 108 cases. Regarding odontogenic keratocyst, histopathological diagnosis confirmed 40 cases out of 48. Conclusion: Radiological diagnoses of the lesions mostly match with their pathological diagnosis unless their characteristics are changed due to infection. CBCT, as a technique enabling detailed imaging of the involved dental structures, is a helpful instrument for differential diagnosis.
