Dentigerous cyst

BACKGROUND: Dentigerous cyst are most common odontogenic cyst and they frequently occur at the mandibular third molar. Their asymptomatic long medical history always resulted in severe bone resorption at the distal aspect of the adjacent second molar. BonMaker® ATB demonstrate an excellent autogenous bone graft candidacy. The aim of this study is to share a single team's experience of dentigerous cyst osseous defect repairing by applying autogenous tooth sticky bone graft. METHOD: In total, 18 patients with dentigerous cyst, which was arised from mandibular third molar unilaterally, were enrolled in this study...

PURPOSE: This study investigated the prevalence of developmental and acquired pathologic conditions associated with impacted third molars (3Ms) in a Southern Brazilian population and evaluated whether demographic and tooth characteristics were correlated with the presence of bone or tooth lesions. MATERIALS AND METHODS: Panoramic radiographs were assessed for developmental (bone-related) or acquired (tooth-related) pathoses associated with impacted upper or lower 3Ms...

Dentigerous cysts are known as the second most common type of cyst in the jaws. The cyst is one of the lesions occurred frequently in the posterior body of the mandible and is often related to the unerupted third molar and forms around the crown of the unerupted tooth attaching at the cementoenamel junction. Such characteristic appearances are the diagnostic points differentiating from ameloblastoma or odontogenic keratocyst. However, it would be hard for us to diagnose it as a dentigerous cyst if the lesion does not show its typical appearance...

Background and Objectives : The purpose of this study was to develop and evaluate a deep learning model capable of autonomously detecting and segmenting radiolucent lesions in the lower jaw by utilizing You Only Look Once (YOLO) v8. Materials and Methods : This study involved the analysis of 226 lesions present in panoramic radiographs captured between 2013 and 2023 at the Clinical Hospital Dubrava and the School of Dental Medicine, University of Zagreb. Panoramic radiographs included radiolucent lesions such as radicular cysts, ameloblastomas, odontogenic keratocysts (OKC), dentigerous cysts and residual cysts...

We evaluated the usefulness of simple diffusion kurtosis (SD) imaging, which was developed to generate diffusion kurtosis images simultaneously with an apparent diffusion coefficient (ADC) map for 27 cystic disease lesions in the head and neck region. The mean kurtosis (MK) and ADC values were calculated for the cystic space. The MK values were dentigerous cyst (DC): 0.74, odontogenic keratocyst (OKC): 0.86, ranula (R): 0.13, and mucous cyst (M): 0, and the ADC values were DC: 1364 × 10-6 mm2 /s, OKC: 925 × 10-6 mm2 /s, R: 2718 × 10-6 mm2 /s, and M: 2686 × 10-6 mm2 /s...

INTRODUCTION AND IMPORTANCE: The association between Dentigerous cysts (DCs) and Gorlin-Goltz syndrome (GGS) was claimed theoretically in a very few reports, with very few clinical foundations. The aim of this report was to present a unique case of multiple DCs in the mandible in a patient showing features of GGS. CASE PRESENTATION: A 63-year-old male patient presented with multiple cyst-like lesions in the mandible associated with some clinical and radiological features of GGS, and that raised the suspension of odontogenic keratocyst (OKC)...

The dentigerous cyst is a developmental odontogenic asymptomatic cyst, that is associated with the crown of an unerupted or impacted tooth. Early diagnosis is important to avoid any future complications and choose the best treatment option. The purpose of this case report is to describe the management of a dentigerous cyst related to lower second molar in a young female patient using orthodontic traction as a conservative treatment approach. This procedure helps to spare the patient an unnecessary surgical excision procedure and the associated excessive bone removal for a safety margin, stimulates bone healing and promotes the eruption of the cyst-associated tooth...

INTRODUCTION: Tartrate-resistant acid phosphatase (TRAP) is an acid phosphatase metalloprotein enzyme expressed in osteoclasts and is related to bone resorption. The molecular mechanisms involved in the different behavior of odontogenic keratocysts have not yet been fully elucidated. The purpose of this study was to compare TRAP expression in odontogenic keratocysts, radicular cysts, and dentigerous cysts. MATERIALS AND METHODS: In this cross-sectional study, we selected 60 samples, including 20 cases of each one of the odontogenic keratocysts (OKC), radicular cysts (RC) and dentigerous cysts (DC)...

Odontogenic cysts are a diverse group of pathologic entities with different proliferation potential, leading to variations in their biological behavior. One of the most cited proliferation markers used in diagnostic histopathology is Ki-67. Another group of proteins recently investigated is minichromosome maintenance (MCM-3) and its expression has been evaluated in several odontogenic lesions but the results were controversial. Thus, the present study endeavored to compare the expression of MCM-3 and Ki-67 in odontogenic cysts...

Among developmental odontogenic cysts, the dentigerous type is the second most prevailing one. It is a benign intraosseous lesion commonly affecting the mandibular region. Dentigerous cysts present a high prevalence in children as they can be caused by the eruption of permanent teeth or the infection of deciduous ones. The adopted treatment modalities include enucleation (cystectomy), marsupialization, and decompression. Decompression maintains communication between the cyst and the oral medium through a sutured fixed device, namely an acrylic stent or a pretrimmed disposable suction tube...

Objectives The pediatric dentigerous cysts might vary by region and population group. Large cystic lesions are typically treated with marsupialization before enucleation in order to decompress the lesion and reduce its volume; however, in pediatric cystic lesions, conservative marsupialization and decompression can be used to manage the condition without additional enucleation. The current study's objectives were to present a case series of pediatric dentigerous cysts and discuss the conservative management of these cystic lesions associated with mixed dentition...

PURPOSES: This study aimed to determine the differential diagnosis of three intraosseous lesions (odontogenic keratocyst (OKC), central giant cell granuloma (CGCG), and dentigerous cyst (DC)) of the dentomaxillofacial region with very similar radiological and clinical features by using chemometrics assisted FT-IR (Fourier transform infrared) spectroscopy in tissue samples. METHODS: Tissue samples (exposed to formaldehyde for a similar time) of 20-micron thickness belonging to 19 intraosseous lesions diagnosed histopathologically were obtained from the pathology laboratory...

Odontomas are considered hamartomatous lesions and are one of the two most common odontogenic tumors of the jaw. Odontomas are classified as compound or complex. Recently, ameloblastic fibro-odontoma (AFO) and ameloblastic fibro-dentinoma were reclassified as developing odontomas. Though clinically odontomas are usually asymptomatic, they have adverse effects on adjacent teeth such as tooth impaction, delayed eruption, displacement of teeth, over-retention of teeth, and can give rise to odontogenic cysts within the jaw...

BACKGROUND: Dentigerous cysts are slow-growing, asymptomatic lesions that typically form around the crowns of impacted teeth. They are not detected until they start to harm the tissues around the teeth. AIM: The present study aimed to describe surgical techniques for treating dentigerous cysts associated with ectopic teeth. CASES: Three patients with dentigerous cysts associated with ectopic teeth, their surgical approaches, and the supporting literature are presented herein...

The microscopic diagnostic differentiation of odontogenic cysts from other cysts is intricate and may cause perplexity for both clinicians and pathologists. Of particular interest is the odontogenic keratocyst (OKC), a developmental cyst with unique histopathological and clinical characteristics. Nevertheless, what distinguishes this cyst is its aggressive nature and high tendency for recurrence. Clinicians encounter challenges in dealing with this frequently encountered jaw lesion, as there is no consensus on surgical treatment...

OBJECTIVE: Differential diagnosis between the non-calcifying variant of calcifying epithelial odontogenic tumor (NCLC-CEOT) and amyloid-rich central odontogenic fibroma (AR-COdF) has become a debate, particularly regarding the frequency of CD1a positivity in both entities. This has led to the growing consensus that CD1a-positive staining in AR-NC lesions confirms the diagnosis of AR-COdF. Here, we assess the validity of this consensus. STUDY DESIGN: We collected the data of a case series of histopathologically distinct CEOTs, NCLC-CEOTs, and COdFs and stained them for CD1a and amyloid...

CONTEXT: Odontogenic cysts and tumours are a wide array of complex pathological entities ranging from mild indolent to aggressive detrimental in nature, which occur as a result of anomalous alterations in normal odontogenesis. Hence, these odontogenic lesions need to be evaluated extensively by using potential immunohistochemical markers. AIM: To evaluate and compare the expression of podoplanin, a lymphoendothelial IHC marker in odontogenic cysts and odontogenic tumours to determine their proliferative potential...

Dentigerous cysts are the second most common odontogenic lesion, after radicular cysts. Dentigerous cysts mainly affect individuals in their second to fourth decades of life, with a slight male predominance. Because diagnosis is often late, surgical procedures like enucleation and removal of the impacted tooth misplaced are often necessary. However, if a dentigerous cyst is detected early in a child with delayed tooth eruption, the treatment goal is to preserve and properly position the permanent tooth within the arch...

PURPOSE: We used proteomic sequencing and experimental verification to identify the potential ferroptosis-related proteins in ameloblastoma. METHODS: Samples of ameloblastoma (n = 14) and normal gingival tissues (n = 5) were collected for proteomic sequencing to identify differentially expressed proteins (DEPs) in ameloblastoma. Ferroptosis-related genes were downloaded from FerrDb V2, which were then compared with DEPs to obtain ferroptosis-related DEPs (FR-DEPs)...

BACKGROUND: Odontogenic cysts have the potential to transform into neoplasms. However, the characteristics of those which transformed to neoplastic tissues have not been well described and the exact causes of that phenomenon are not yet clear. OBJECTIVES: This study aims to describe characteristics of odontogenic cysts that transformed into neoplasms and to look for their potential etiologies. DATA SOURCES: English-written studies indexed in PubMed, Science Direct, and Proquest were assessed using keywords verified by Medical Subject Headings: 'Odontogenic Cyst' and 'Neoplastic Cell Transformation'...
