RESUMEN

BACKGROUND: To investigate the radiological and demographic features, types, distribution, and treatment methods of dentigerous cysts (DC). METHODS: Panoramic radiographs and cone beam computed tomography (CBCT) images of patients diagnosed with DC based on biopsy results between January 2020 and December 2023 were examined. In patients from different age groups, the numbers, types and locations, and radiological features of DCs, associated changes in surrounding tissues, and treatment methods used were reviewed. RESULTS: Among 95 patients with DC (66 males, 29 females), sex and age distributions were comparable between those with a single cyst (n = 86) and those with two cysts (n = 9). Of 104 DCs, 44 were central, 38 were lateral, and 22 were circumferential. DC types were not significantly affected by sex, age group, or anatomical location. Circumferential DCs often caused displacement of the mandibular canal inferiorly. While enucleation was preferred for the treatment of central DCs, circumferential DCs were treated with marsupialization. CONCLUSIONS: In this study, which is the first to evaluate the DC types on CBCT images, the central type was the most common. Circumferential DCs were mostly treated with marsupialization. CBCT imaging can assist in determining DC types, and may provide guidance for treatment planning.

RESUMEN

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. We experienced two cases of dentigerous cysts which did not form around the crown of the unerupted tooth on radiologically. Both cysts were relatively large and resorbed adjacent teeth roots. Therefore, an ameloblastoma or an odontogenic keratocyst was suspected rather than a dentigerous cyst as the imaging diagnosis. The biopsy revealed that the lesion was a "dentigerous cyst" in one of the cases and "developmental cyst with inflammation" in another case. After the excision, the histopathological diagnosis was a dentigerous cyst with inflammation in both cases. This report shows the two cases of dentigerous cysts focusing on panoramic radiography and CT images. Also, we discuss the differential diagnosis by reconsidering those diagnostic points.

RESUMEN

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.

RESUMEN

Bilateral dentigerous cysts (DC) associated with unerupted mandibular first molars in a non-syndromic pediatric individual are rare. Secondary infections may lead to complications, such as discomfort due to pain, disfigurement caused by enlargement of the cyst with cortical expansion of the jawbone, displacement of teeth and paraesthesia of the adjacent nerve. This case report describes the occurrence of bilateral DC in an eight-year-old patient. Marsupialization was the treatment of choice to preserve the permanent teeth and other adjacent tissues.

RESUMEN

A male patient aged 11 years presented a large dentigerous cyst in the lower left quadrant associated with retained deciduous lower lateral incisor and canine and impacted, unerupted corresponding permanent ones. The treatment consisted in marsupialisation and placement of a modified lingual arch that held a tube for decompression used for irrigation of the cystic cavity in a comfortable way for the patient and for the clinician.The same lingual arch was later used as an anchorage method for traction of the retained teeth. The final records showed complete resolution of the cyst and retained teeth were successfully Aligned into the oral cavity.

RESUMEN

Feline cystic oral lesions are uncommon and include odontogenic cysts and cystic odontogenic tumors. Accurate diagnosis requires close collaboration between the clinician's clinical and radiographic findings and the pathologist's histologic interpretations. The odontogenic cysts identified in this series include a periapical cyst, dentigerous cysts and a type of unclassified collateral cyst that appears to be a previously undefined, distinct entity in cats (UCC). Many of the cysts (52%) were unable to be classified due to insufficient diagnostic information, which often related to the associated tooth being unavailable for evaluation. Cystic odontogenic tumors included ameloblastomas, amyloid producing ameloblastomas (APA), and feline inductive odontogenic tumors (FIOT). The purpose of this case series was to assess correlations between clinical and radiographic findings, histopathologic interpretation and signalment to identify common characteristics and provide recommendations for clinicians and pathologists to optimize diagnostic efficiency and accuracy for cystic oral lesions in cats.

RESUMEN

Unicystic ameloblastoma (UAM), a rare variant of ameloblastoma, is an odontogenic epithelial neoplasm typically appearing in the mandible. We report an extremely rare case of maxillary UAM with an impacted canine and supernumerary tooth. The patient was a woman in her late 30s who presented with a slight expansion of the left anterior maxilla due to a cystic lesion with impacted teeth. Under a clinical diagnosis of dentigerous cyst, the cystic lesion was completely enucleated by extracting the impacted teeth. Based on the clinical features and pathological findings, the final diagnosis was intraluminal UAM in the anterior maxilla. In the present case, despite the rarity of UAM with impacted teeth in the anterior maxilla, it should be considered during differential diagnosis. Careful clinical examination is required for diagnostic accuracy since the clinical findings of tooth-containing ameloblastoma and dentigerous cyst are very similar.

RESUMEN

The purpose of this article is to show alternate management of an anterior maxillary dentigerous cyst in a paediatric patient. An 8-year-old male child reported to the Department of Oral and Maxillofacial surgery with the chief complaint of swelling in the upper left side of the face for 2 months. Based on the clinical and radiological findings of cystic cavity along with impacted tooth, lesion was diagnosed as dentigerous cyst and surgical enucleation was planned under general anaesthesia. Dentigerous cysts mostly occur in the mandible and are prevalent between the second to fourth decades of life. The incidence of this cyst in children is less. We present here a case report of a paediatric patient with a rare occurrence of a large cyst in the maxillary anterior region, and the treatment outcome by surgical enucleation and preservation of the permanent tooth bud are discussed. The line of treatment for dentigerous cyst is enucleation and extraction of involved tooth. We recommend the alternative treatment option, which involves enucleation of cyst, and consider the conservation of the affected tooth bud in the view of making its eruption viable in future.

RESUMEN

The earliest reported case of the occurrence of a dentigerous cyst is described; the cyst surrounded an unerupted permanent tooth bud in a 6-month-old infant. Most commonly these lesions present between the second and third decades of life. They rarely occur before 10 years of age and have not been documented prior to 1 year of age. In the case reported here, the treatment instituted was extraction of the adjacent deciduous tooth and enucleation of the cyst along with the permanent molar tooth bud. Clinicians should be aware of the potential for this lesion to occur across a wide range of ages and the importance of prompt diagnosis and treatment to prevent complications and reduce morbidity.

RESUMEN

Mucopolysaccharidosis VI is a genetic disorder affecting multiple organs with sundry clinical presentations. The main etiological factor reflects the disturbances in mucopolysaccharide metabolism leading to deposition of acid mucopolysaccharide in various tissues. The pathognomonic features of the disease include a large head, short neck, corneal opacity, open mouth associated with an enlarged tongue, enlargement of the skull, and long anteroposterior dimension with unerupted dentition, dentigerous cyst-like follicles, condylar defects, and gingival hyperplasia. An 18-year-old boy with Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) is described in this article, emphasizing the oral manifestations and radiographic illustration of lesions in the jaws. It also emphasizes the essential role of cone-beam computed tomography to identify and analyze multicentric pathologies in the jaws.

RESUMEN

An association between unerupted teeth and dentigerous cysts is well known,1- 4 however little is known about the presence of disease and histopathologic changes in unerupted teeth without radiographic evidence of cyst formation. Forty-two dogs representing 25 breeds, ranging in age from 5 months to 12 years were selected based on radiographic evidence of an unerupted tooth or teeth, either as a primary complaint or incidental finding. Dogs meeting the study criteria were presented to a private dental referral practice within a period of eighteen months from December 2016 through May 2018. Patients were treated with conservative en bloc resection of the unerupted tooth and overlying bone as well as debridement of any cystic structure and biopsy of the samples collected. Radiographs were evaluated using criteria previously established to assess for evidence of a cyst.1, 5- 7 A total of 68 unerupted teeth were identified; 63 (92.7%) were mandibular first premolar teeth. Of the 63 unerupted mandibular first premolar teeth, 28 (44.4%) had radiographic evidence of a cystic structure. Histopathology revealed that 21 of 28 (75.0%) had evidence of non-keratinizing stratified squamous epithelium consistent with a cyst lining. Of the remaining 35 of 63 (55.6%) mandibular first premolar teeth with no radiographic evidence of a cyst, 27 (77.1%) had no histologic evidence of epithelium associated with the impacted tooth. Notably however, the remaining 8 of 35 (22.9%) unerupted teeth without radiographic evidence of a cyst did have histologic evidence of non-keratinizing stratified squamous epithelium associated with the impacted tooth.

RESUMEN

AIM: This study aimed to evaluate the contribution of the MRI and CT results to the differential diagnosis of histopathologically different odontogenic cysts. BACKGROUND: Odontogenic cysts are commonly seen in the jaw bone and their surgical operations have an important place in the practice of maxillofacial surgery; treatment options for these cysts differ according to their histopathology. Differential results that can be obtained from the radiological evaluations of different cyst groups will allow the surgeon to plan a more accurate approach at the beginning of the operation. In this study, computed tomography (CT) and magnetic resonance imaging (MRI) results of different cyst groups were interpreted together with their histopathological diagnosis. METHODS: CT and MRI results of 17 patients aged between 19-61 were evaluated, whose histopathological diagnosis consisted of 3 radicular cysts (RC), a total of 9 odontogenic keratocysts (OKC) of which 4 were inflamed, and a total of 5 dentigerous cysts (DC) of which one of them was inflammatory. RESULTS: In the CT scan, all cysts showed lytic, a sclerotic surrounding, and showed MRI peripheral enhancement, whereas solid nodular enhancement was only observed in OKCs. Edema and/or air in the surrounding bone medulla was observed in the infected lesions. OKC was heterogeneous, whereas RC and DC were more homogeneous. Diffusion restriction was observed to be frequent in OKCs. The OKCs were ellipsoidal in appearance and were located parallel to the long axis of the bone, and their dimensions were observed to be larger than the other cysts. OKCs may be accompanied by unerupted teeth. Radicular cysts were located perpendicular to the long axis of the bone and were globular in appearance, and their dimensions were smaller and more homogeneous compared to the OKCs. Dentigerous cysts are also accompanied by an unerupted tooth, and their peripheral enhancement is minimal and homogeneous. However, dentigerous cysts can be dense in content and smaller in size, and ellipsoidal localization is more common than OKCs. CONCLUSION: In addition to classic panoramic radiography in the evaluation and differential diagnosis of maxillary and mandibular lesions, CT and MRI evaluations can provide helpful information to the surgeon and pathologist in making the diagnosis and may further help plan the operation.

RESUMEN

Odontogenic tumours and cysts have a characteristic presentation, histopathologically and clinically. The diagnostic criteria and nomenclature are distinct as elaborated in 2017 WHO classification. But one can occasionally and infrequently find an association between different odontogenic tumours and cysts, like calcifying epithelial odontogenic tumour (CEOT) and adenomatoid odontogenic tumour (AOT), CEOT and ghost cell tumour. Some of the odontogenic tumours and cysts share the site of occurrence, intraosseous location, teeth involved/quadrant involved and histopathology too. Hence these lesions are considered for differential diagnoses in most cases. But some instances report hybrid or associated tumours and cyst cases. Here we present a case of dentigerous cyst in association with AOT that showed variation in cell type, pattern and induction pattern.

RESUMEN

OBJECTIVE: To evaluate the histopathologic outcomes of pericoronal radiolucencies and identify factors predictive of diagnosis. STUDY DESIGN: A retrospective cohort study of 258 patients with 280 radiolucent pericoronal lesions undergoing treatment at our institution between 2005 and 2019. The primary predictor variable was lesion size (≥2 cm and <2 cm). The primary outcome variable was histopathologic diagnosis (dentigerous cyst vs other pathologic entity). Descriptive, bivariate, and multiple logistic regression statistics were computed to measure the association between clinical and radiographic variables and histopathologic diagnosis. RESULTS: The study sample was composed of 258 patients with 280 histopathologic specimens. There were 218 dentigerous cysts (77.9%) and 62 other pathologic entities (22.1%). Lesions ≥2 cm were 3.20 times more likely to be diagnosed as a nondentigerous cyst pathologic entity (P ≤ .001). After adjusting for jaw (maxilla vs mandible), pain, history of infection, cortical perforation, expansion, and multiple lesions, younger age (P ≤ .001, odds ratio [OR] = 0.950, 95% confidence interval [CI] = 0.929-0.972) and lesion size as a continuous variable (P = .007, OR = 1.06, 95% CI = 1.02-1.11) were independent predictors of other pathologic entities. CONCLUSIONS: The majority of pericoronal radiolucent lesions were dentigerous cysts. Younger age and larger lesions were independent predictors of other pathologic entities.

RESUMEN

Objetivos: Demostrar la utilidad y la facilidad técnica del injerto tibial en defectos óseos orales y maxilofaciales, para tenerlo como un recurso alternativo en la práctica general del cirujano oral y maxilofacial. Caso clínico: Se presenta un caso clínico con el uso de injerto óseo autólogo de tibia para el relleno de un defecto óseo a raíz de una lesión quística. Se realizó la exéresis de la patología quística por medio de un abordaje oral y posteriormente se recolectó hueso medular tibial a través de un abordaje medio al tubérculo anterior de la tibia, para poder colocarlo en el defecto óseo. Conclusión: El injerto de hueso medular de epífisis tibial representa un sitio de recolección de fácil acceso, del que se puede obtener una cantidad de hueso ideal para defectos de pequeño y mediano tamaño de la región maxilofacial, de baja morbilidad y con muy pocas complicaciones post-operatorias, lo que lo convierte en una alternativa para rellenos de cavidades óseas de gran utilidad (AU)


Objective: To demonstrate the utility and technical ease of the tibial graft in oral and maxillofacial bone defects so as to have it as an alternative resource in the general practice of the oral and maxillofacial surgeon. Case report: A clinical case is shown with the use of an autologous tibial bone graft to fill a bone defect as a result of a cystic lesion. The cyst was excised by an oral approach and the medial tibial bone was collected through a middle approach to the anterior tubercle of the tibia, to place it in the bone defect. Conclusion: The tibial epiphysis medullary bone graft represents an easily accessible collection site, from which an ideal amount of bone can be obtained for small and mediumsized defects of the maxillofacial region, with low morbidity and very few post-operative complications, which makes it a useful option for bone cavity filling (AU)

RESUMEN

Dentigerous cysts, also known as follicular cysts, are among the most common developmental cysts of the gnathic bones. The majority of cases are clinically asymptomatic and discovered incidentally on panographic radiographs during routine dental care. The cyst appears as a radiolucency, classically unilocular, associated with the crown of an unerupted or impacted tooth. Usually diagnosed in the 2nd-3rd decade, third molars of the mandible are the most commonly affected teeth. Histologically, dentigerous cysts demonstrate a fibrous or fibromyxoid connective tissue wall lined by squamous epithelium, classically lacking rete ridges. Inflammation may introduce histologic changes, however. The differential diagnosis includes hyperplastic dental follicle, periapical or radicular cyst, unicystic ameloblastoma, odontogenic keratocyst, and other odontogenic cysts and tumors. While the findings are generally classic and pose no diagnostic dilemma, the diagnosis is best made in the context of the appropriate clinical and radiographic setting. Submitted tissue with a lack of history, to include a detailed relationship with the affected tooth, may result in misdiagnosis and subsequent confusion for the clinician. So, despite its simple features, dentigerous cysts are not uncommonly mischaracterized. Therefore a review of a classic case of dentigerous cyst is presented.
