Tratamento cirúrgico de tumor odontogênico queratocístico: relato de caso

Introduction: The Keratocystic Odontogenic Tumor (KCOT) is a benign odontogenic tumor with an infiltrative and potentially aggressive behavior with high recurrence rates. The KCOT occurs more often in men than women, with a frequency of 2:1, being more frequent in the mandible with a predilection for the body and branch. Treatment of KCOT remains controversial. Treatment usually includes enucleation, marsupialization, peripheral ostectomy, curettage associated with Carnoy solution and resection. Objective: To report a case of a KCOT located in the mandible. Case report: male patient, 15 years, with a KCOT on the right side of the mandible treated by enucleation and peripheral ostectomy, with four years of preservation, with no signs of recurrence. Final Comments: The treatment by enucleation associated with peripheral ostectomy reduces the relapse rate, preserves anatomical structures and can avoid a second surgical procedure for reconstruction of bone defects generated in surgery en bloc resection.

Lateral periodontal cyst: a case report and literature review

The lateral periodontal cyst is considered a developmental odontogenic cyst with unusual occurrence. In most cases it is preliminary diagnosed as a radiographic finding, presenting as well circumscribed or as a round or teardrop-shaped radiolucent area. Due to its location it can easily be misdiagnosed as a lesion of endodontic origin. Final diagnosis should be based on histopatological examination. The purpose of this paper is to report a classic case of lateral periodontal cyst located in the anterior region of mandible and to review the relevant literature which describes the clinical, radiological and histopathological features of lateral periodontal cysts. A 50 years female patient complained of an asymptomatic gingival swelling in the region between the left mandibular lateral incisor and canine. Radiographic examination revealed a well circumscribed radiolucency with approximately 0.5 cm diameter with a radiopaque margin between the roots of the left mandibular lateral incisor and canine. The adjacent teeth had vital pulp. A total enucleation of the lesion was performed, and intraoperative examination showed a single lesion with no communication between the cyst's cavity and the oral environment. Histological examination revealed that the lesion was lateral periodontal cyst of developmental origin. There was no recurrence or complications for 24 months follow-up. The lateral periodontal cyst can be considered in the differential diagnosis when a radioloucent lesion appears adjacent to the roots of vital teeth. The treatment of choice is surgical removal and subsequent histological evaluation to confirm the diagnosis. Relapses are infrequent.

Impacted permanent incisors associated with compound odontoma

Odontomas are the most common odontogenic tumours of the maxillary bones, characterised by a slow growth and benign behaviour. They are usually small, asymptomatic and diagnosed after routine radiographic examination. The aim of this study was to report a case of a compound odontoma in the anterior maxilla of a 7-year-old girl, which was causing the impaction of the maxillary right central and lateral incisors, as well as the prolonged retention of the corresponding primary teeth. We also aimed to review the literature about these tumours, since they are not part of the dentist's day-to-day clinical practice. The clinical and radiographic features, the diagnosis and treatment of the case were discussed in this work.

Tumor odontogênico queratocístico e considerações diagnósticas

Keratocystic odontogenic tumor (KCOT is benign, featuring controversies in diagnosis and treatment. It occurs mainly in the region of the mandibular angle, which may or may not be related to a tooth and whose importance is due to its aggressive behavior and high recurrence rate. The causes of high rates of relapse observed in this lesion are dependent on factors such as age, location and size of lesion, gender, type of treatment and histological variant. The thin capsule and friable connective tissue of KCOT may favor the retention of epithelial debris responsible for the high proliferative capacity of this clinical entity. Due to the aggressiveness with its recurrence this paper aims to conduct a literature review addressing clinical and imaging aspects, composes the histopathological diagnosis of KCOT.

Tumor odontogênico queratocístico: considerações clínico-cirúrgico

Introduction: The tumor odontogenic keratocyst (toq) is a benign disorder, which is controversial in its diagnosis and treatment. It is characterized by a true neoplasms arising from remnants the dental lamina. It occurs predominantly in the angle mandible, which may or may not be related to a tooth and whose importance is due to its aggressive behavior and high recurrence rate. The causes of the high recurrence rates. The thin capsule and friable tissue may favor the toq retention of epithelial debris and, moreover, the presence of satellite cells in the lesion site is responsible for the increased proliferative capacity of clinical entity. Objective: To present the peculiarities toq inherent in using a clinical case of toq in mandible. Case report: TOQ in the jaw in patient, 16 years old male presenting important lesion radiographically radiolucent related to the impacted tooth. Final comments: In consideration of the high rate of recurrence chosen treatment proved effective and was not any evidence of recurrence.

Tumor odontogênico queratocístico: relato de caso

Introduction: The odontogenic keratocyst tumor (OKT) derived from dental lamina rests with particularities and specific histological features, with high rates of relapse and aggressive clinical behavior. Presents certain predilection for males, affecting the mandible of 60% to 80% of cases may be related to impacted tooth 25 to 45% of cases. Objective: To highlight the clinical, histopathological and imaging procedures of the OKT, as well as discuss the treatment of this injury. Case Report: To report a case of 10 years of age to look for the orthodontist to correct anterior open bite was observed in panoramic radiography radiolucent area in the region of the body of the mandible associated with pathological inclusion of the lower premolar. It was performed an incisional biopsy of the lesion and the histopathologic diagnosis was odontogenic keratocyst tumor. It was performed a CT scan to assess the extent of the injury and its relation to anatomic structures. How to conduct, we opted for the extraction of the deciduous molar and enucleation of the lesion, preserving the premolar included. The same goes on clinical and radiographic control 18 months, after removal of OKT obtaining the eruption of premolar that was involved in the injury. Final Comments: It is necessary to adopt protocols that include dental care knowledge of oral diagnosis, medical history and careful clinical evaluation without forgetting the need for histopathological confirmation.

Quarto molar retido: a importância do diagnóstico precoce

Introductions: A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. Its etiology is not fully understood. With regard to its prevalence, it occurs more commonly in permanent dentition and twice as often in men than in women. Supernumerary teeth are classified according to their morphology and location. Their presence can cause problems such as failure of eruption, displacement of teeth, crowding and odontogenic cysts and tumors. The diagnosis is usually by routine radiographs, for the majority of such teeth are impacted and asymptomatic. Objective and Case report: The purpose of this study was to make a brief review of the relevant literature and report one clinical case of the female patient, 23 years, melanoderma, featuring three quarters molars. Final considerations: The early diagnosis proved to be important for the resolution of the case in order to minimize or even prevent the development of complications and thus establish a proper plan of treatment.

Tumor odontogênico queratocístico: revisão de literatura

The odontogenic keratocyst is called keratocyst odontogenic tumor (TOQ), due to its features compatible with neoplasms, such as its high recurrence rate and mechanism of growth. Although its etiology has unknown, the origin seems to be connected with dental lamina remaining. This entity is generally benign, with slow progression, asymptomatic, and among the odontogenic tumors, its prevalence is high. It affects mainly males, with predilection for the posterior mandible, while in most cases associated with an impacted tooth. Radiographically, this lesion is unilocular. Histological features are stratified epithelial basal cells with hyperchromatic paraqueratinizado. Treatment ranges from conservative to radical interventions. As a result of the controversy as TOQ tumor entity, the present work is a literature review of current findings, emphasizing its intrinsic features to contribute to developments in the study of this new entity.

Estudo radiográfico de terceiros molares inferiores retidos e parcialmente irrompidos e revisão de literatuda

Introduction: Pathology associated with retained or partially erupted teeth are common in the general population. Objective: the aim was to evaluate the measurement of pericoronal space of retained third molars and partially erupted teeth in panoramic radiographs. Method: a retrospective study was carried on on the frequency of tooth retention and the problems it can cause in 107 radiographs of patients where the width was measured to verify the presence or absence of diseases associated with the involved teeth. Results: in the 107 panoramic radiographs analyzed the most frequent measurement was of 1.0 mm with 32.71% of cases followed by 2.0 mm with 29.91% of cases. Conclusion: The measurement of the pericoronal sapce of retained third molars and partially retained through its greatest width is in a practical and effective technique for application in routine clinical practice, which suggests the presence or absence of eraly odontogenic pathology

Odontoma em pacientes odontopediátrico: diagnóstico e tratamento. Relato de caso clínico.

Odontoma is a term that refers to a benign tumor of odontogenic and mixed nature, composed of epithelial and mesenchymal components. Histologically, they are compounds of different configurations including dental enamel, dentin, cementum and in some cases the pulp tissue. A slow growing asymptomatic tumor, odontoma is usually discovered through routine radiographic examination. A 3-year old male patient sought care at the School of Dentistry’s Baby Clinic (UNESP-Araçatuba), complaining of “small ball close to the teeth.” During the interview, the mother reported that the lesion was observed soon after a trauma, and evolved in less than one month. An ulcerated lesion with a 0.8 cm diameter was found during intraoral clinical examination. It was located in the inferior and anterior region of the mouth, between teeth 81 and 82, and there was also crown distalization. A radiographic examination showed a radiolucent area and root distance. In the absence of clinical and radiographic characteristics suggesting a case of odontoma, the differential diagnosis was peripheral giant cell lesion and pyogenic granuloma. So the area was punctured. Nonetheless, due to the absence of liquid, the surgical removal of the lesion was performed, followed by histological examination, which showed the definite diagnosis of a suggestive case of emerging odontoma.

Tratamento cirúrgico de ameloblastoma mandibular

Ameloblastomas are benign, invasive locally and highly recurrent. It is an odontogenic tumor, characterized by the proliferation of epithelial ameloblastic in a fibrous stroma. This paper reports a case of mandibular ameloblastoma, in patients 27 years of age without pain with developments around 4 years, with about 20 mm at its greatest extent, sessile base and surface coatings full. The treatment of choice was the surgical conservative

Lymphoepithelial cyst in jugal mucosa

Mouth lymphoepithelial cyst is rare, with few cases reported in literature. The aim of this article is to describe a clinical case, focusing on clinical and diagnostic aspects, treatment and prognosis. The lesion was one year old and had developed as a fibrous nodule in the jugal mucosa of a 71-year-old leucoderma patient. Considering focal inflammatory fibrous hyperplasia, fibroma and mucocele as differential diagnosis, excisional biopsy was carried out. A cystic cavity limited by pseudostratified epithelium without projections into the conjunctive tissue, with lymphoid tissue within, was microscopically identified. Without postoperative adverse events, the one-year clinical followup confirmed the favorable prognosis of this kind of lesion.

Infecções odontogenicas: relato de caso clínico e implicações terapêuticas

Acute infections maxillo-facial are of great importance, both for its high population, as the risk of complications. The aim of this study was to present a clinical case of extensive odontogenic abscess in a patient of 31 years of age attended the Service of Surgery and Maxillo-Facial, Faculty of Dentistry of Araçatuba - UNESP in Araçatuba, SP. Complications of infections odontogências although infrequent can lead the patient to death.

Cisto ósseo simples: relatos de casos

Usually diagnosed in routine radiographs, the simple bone cyst occurs infrequently. Etiology is unknown and differential diagnosis has to be made with dentigerous cyst, keratocystic odontogenic tumor, adenomatoid odontogenic tumor, ameloblastoma and central giant cell granuloma. Treatment is surgical, by perforating the cortical bone. In most cases an empty cavity, without any capsule or epithelial covering, is encountered, but it may have a liquid content. Perforation of the mandibular cortical bone elicits a response that results in bone repair of the empty cavity. This article reviews the subject and presents two cases of this entity and discusses the possible factors that could interfere in healing course.
