INTRODUCTION: The role of the volume of radicular and dentigerous cysts on clinical symptoms is unclear and potentially may predict development of pre- and postoperative complications, especially after cystectomies with large bony defects. Therefore the aim of this study was to assess pre- and postoperative symptoms associated to the volume of jaw cysts. MATERIAL AND METHODS: Retrospective chart review of 111 patients with follicular or dentigerous cysts from 2008-2012...

OBJECTIVES: An odontogenic keratocyst (OKC) is a developmental odontogenic cyst with aggressive clinical behavior. This cyst shows a different growth mechanism from the more common dentigerous cyst and now has been renamed as a keratocystic odontogenic tumor (KCOT). Inflammation can assist tumor growth via different mechanisms including dysregulation of the p53 gene. This study aims to assess and compare the expression of tumor suppressor gene p53 in inflamed and non-inflamed types of OKC and dentigerous cyst...

We prospectively investigated in adults the decompression of dentigerous cysts associated with impacted third molars at high risk of iatrogenic damage during extraction. The computerised calculated volumetric postoperative reductions measured by cone-beam computed tomography at four and eight months were correlated with the duration of treatment, initial volume, and patient's age. We prospectively monitored 14 adult patients with 14 dentigerous cysts that were associated with impacted third molars, for eight months after decompression...

INTRODUCTION: An array of odontogenic lesions manifest in the maxillofacial region with variable presentations. The biological behavior of lesions, such as odontogenic keratocyst (OKC), dentigerous cyst (DC), and ameloblastoma (AM) always invite debate. Glucose transporter 1 (GLUT-1) is proven to be an indicator of metabolic behavior of several benign and malignant neoplasms. AIM: The purpose of this study was to evaluate the expression of GLUT-1 in OKC, DC, and AM to understand their metabolic behavior...

OBJECTIVES: Apical periodontitis can appear clinically as apical granulomas or radicular cysts. There is evidence that immunologic factors are involved in the pathogenesis of both pathologies. In contrast to radicular cysts, the dentigerous cysts have a developmental origin. Macrophage polarization (M1 vs M2) is a main regulator of tissue homeostasis and differentiation. There are no studies comparing macrophage polarization in apical granulomas, radicular cysts, and dentigerous cysts...

Ameloblastoma is classified as a benign odontogenic tumor characterized by locally invasive behavior and high risk of recurrence. Here, we evaluate a potential role for glycosaminoglycan, a structural component of cell membranes and extracellular matrix, in ameloblstoma pathogenesis. We subjected formalin-fixed, paraffin-embedded tissue sections of 34 cases of ameloblastoma, 10 of odontogenic keratocyst, and 17 of dentigerous cyst to immunohistochemistry using monoclonal antibodies recognizing chondroitin sulfate A (CS-A), heparan sulfate (HS), and keratan sulfate (KS)...

Dentigerous cysts are benign odontogenic cysts associated with the crowns of unerupted, embedded, or impacted teeth. Most of them are associated with mandibular third molars, followed by maxillary third molars and canines. They are usually asymptomatic, and rarely do they grow extensively and compress the adjacent anatomic structures. We report 5 cases of extensive maxillary dentigerous cysts presenting with sinonasal and orbital symptoms. A literature review for similar presentations of dentigerous cysts has demonstrated 21 cases...

Central odontogenic fibroma (COF) represents a rare group of benign odontogenic tumor, while dentigerous cyst (DC), on the other hand, is the odontogenic cyst that encloses the crown of an unerupted tooth. A combination of COF and DC is rare and not reported in literature till date. The aim of this paper is to report a case of COF occurring concurrently with DC. The simultaneous occurrence of COF and DC raises the question of whether it is a collision tumor or their simultaneous occurrence is just a coincidence...

The calcifying odontogenic cyst is a rare developmental odontogenic lesion with a distinguishing cystic lining containing "ghost" epithelial cells. The variation in clinical, radiographic, and histologic findings makes the treatment decision difficult for these lesions. There are very few reports on treatment, with enucleation and curettage being the standard surgical method of choice for the cystic type and excision of the tumor for the solid type. A 2-stage surgical approach consisting of initial decompression with tube placement followed by a secondary procedure of enucleation and curettage is common for other large odontogenic cysts, such as dentigerous and odontogenic keratocysts...

In the present study, we sought to: (a) analyze the p53 gene status in dentigerous cysts (DC) associated with supernumerary teeth (ST) in a pair of siblings with ST, of whom one developed a DC; and (b) conduct a narrative review of the literature on ST associated with DC. Blood samples were obtained, and the isolated DNA was used to amplify exons 4-8 of the p53 gene using specific primers, and subsequently sequenced. No mutations were identified in the coding regions of the p53 gene. A review of the literature revealed a prevalence of DC associated with ST to be as high as 13...

Dentigerous cysts are the most common developmental odontogenic cysts of the jaw, which usually occur in the second and third decade of life. It is most frequently associated with impacted mandibular third molar teeth and impacted canines. Bilateral/multiple dentigerous cysts are rare and typically associated with developmental syndromes. Non-syndromic dentigerous cyst occurring bilaterally or involving both arches at the same time is very rare. Here, we discuss the review of literature with a case of unusual occurrence of non-syndromic bi-maxillary dentigerous cysts in a child...

Diagnosis and preoperative planning are critical in the execution of any surgical procedure. Panoramic radiography is a routine method used in dentistry to assist clinical diagnosis; however, with this technique 3D anatomical structures are compressed into 2D images, resulting in overlapping of structures which are of interest in the diagnosis. In this study we report the case of a patient who presented with a dentigerous cyst of expressive dimensions in the body of the mandible region. The surgery was planned and executed after observing the margins of the lesion by Cone Beam Computed Tomography (CBCT)...

Mandibular swellings may occur as a result of many benign lesions of odontogenic or non-odontogenic origin. Ameloblastomas are benign tumours of odontogenic origin, whose importance lies in its potential to grow into enormous size with resulting bone deformity, it is a slow-growing, persistent, and locally aggressive neoplasm. The unicystic ameloblastoma (UA) represents an ameloblastoma variant, presenting as a cyst clinically and radiographically, but showing typical ameloblastomatous epithelium lining histologically...

A 15-year-old Indian male patient presented with a history of pain and swelling in left mandible. Imaging studies revealed a well-defined unilocular radiolucency in the body of the mandible. Patient also gave the past history of the surgery of the jaws, which was histopathologically diagnosed as dentigerous cyst. Following this patient underwent incisional biopsy and later excisional biopsy. The histopathologic diagnosis for incisional biopsy was unicystic ameloblastoma but final diagnosis was dentinogenic ghost cell tumor for the excised tissue...

OBJECTIVES: Odontogenic cysts and tumors are the most relevant lesions that affect the gnathic bones. These lesions have in common the formation of cystic areas and this common feature may suggest involvement of similar mechanisms. The hypoxia inducible factor 1 alpha (HIF-1α), a responsive protein to hypoxia and caspase-3, an irreversible apoptosis marker, may contribute to cyst formation. Thus, this study aimed to investigate the immunoexpression of these proteins in odontogenic cysts and tumors...
