ABSTRACT Alveolodental ankylosis is the fusion of cementum or root dentin with the alveolar bone in both deciduous and permanent teeth. This leads to important clinical and radiographic changes in the affected teeth. Moreover, knowledge of the biological principles involved allows adequate management of teeth affected by this phenomenon.
RESUMO A anquilose alveolodentária consiste na fusão do cemento ou dentina radicular com o osso alveolar tanto em dentes decíduos como nos dentes permanentes. Isto leva a uma série de alterações clínicas e radiográficas importantes para o diagnóstico. Além disso, o conhecimento dos princípios biológicos envolvidos irá permitir o controle adequado dos dentes acometidos por este fenômeno.
RESUMO
Non-Hodgkin lymphoma is the second most common neoplasm of the head and neck after squamous cell carcinoma. However, it accounts for only 3.5% of all malignancies of the oral cavity. Oral lesions are often a component of disseminated disease process that may involve regional lymph nodes or may at times represent the primary extra nodal form of the disease. Although, isolated oral lymphoma in adults is extremely rare, this paper presents a patient with Burkitt lymphoma in an adult male with atypical clinical presentation primarily involving the oral soft tissue. It is believed that the prognosis of Burkitt lymphoma depends on the extent of the disease, the patient's age, and the timing of diagnosis. Therefore, the role of the dentist in the early diagnosis and prompt referral of patients with Burkitt lymphoma cannot be overemphasized.

Unicystic ameloblastoma is a distinguishable entity of ameloblastomas, characterized by slow growth and being relatively locally aggressive. Three histological types are recognized according to the degree of ameloblastomatous epithelial extension, namely, luminal, intraluminal, and mural types. This classification has a direct bearing on their biological behavior, treatment, and prognosis. However, there is difficulty in determining the most appropriate form of treatment for unicystic ameloblastoma. We present a case of unicystic ameloblastoma that occurred in the right posterior mandible of 19-year-old girl, which was enucleated and did not recur after 12-month follow-up.
RESUMO
O cementoblastoma benigno ou cementoma verdadeiro é uma neoplasia odontogênica benigna. Acredita-se que essa lesão é a única neoplasia verdadeira do cemento. Ela apresenta incidência entre 1 e 6,2% dentre os tumores odontogênicos, o que vem a tornála rara. Sendo assim, o objetivo do presente trabalho foi relatar o caso clínico de uma paciente com diagnóstico de cementoblastoma benigno, enfatizando as peculiaridades desse tumor, a importância do diagnóstico correto e o estabelecimento de um tratamento adequado, bem como ressaltar a importância da proservação do caso.
Benign cementoblastoma or true cementoma is a benign odontogenic tumour. It is believed that this lesion presents the unique true cementum neoplasm. It is a rare lesion comprising 1 to 6,2% of odontogenic tumours. Therefore, the objective of this study was to report the case of a patient diagnosed with benign cementoblastoma, emphasizing the peculiarities of this tumor, the importance of correct diagnosis and appropriate treatment setting, as well as underscoring the importance of proactive observation.

Os cistos são lesões formadas por uma cavidade revestida de tecido epitelial, as quais contêm, em seu interior, material líquido ou semisólido, podendo ser classificados em cistos odontogênicos e não odontogênicos. Apesar de existirem diversas modalidades de tratamentos descritas na literatura para tratamentos dos cistos da cavidade oral, até o presente momento, não se observa um consenso em relação à qual técnica que oferece os melhores resultados. Sendo assim, procurou-se relatar um caso clínico com a utilização da técnica de descompressão, procurando evidenciar suas indicações, vantagens, desvantagens e demais peculiaridades... (AU)

UNLABELLED: The pathogenesis of alveolitis is not well known and therefore experimental situations that mimic some features of this disease should be developed. OBJECTIVE: In this study, the evolution of the experimentally induced infection in rat sockets is characterized, which leads to clinical signs of suppurative alveolitis with remarkable wound healing disturbs. MATERIAL AND METHODS: Non-infected (Group I) and experimentally infected sockets in Rattus novergicus (Group II) were histometrically evaluated regarding the kinetics of alveolar healing. In addition, the characterization of the present bacteria in inoculation material and the serum levels of C-reactive protein (CRP) were performed. The detected species were Capnocytophaga ochracea, Fusobacterium nucleatum ss nucleatum, Prevotella melaninogenica, Streptococcus anginosus, Treponema socranskii and Streptococcus sanguis. RESULTS: All experimentally infected rats developed suppurative alveolitis, showing higher levels of CRP in comparison to those non-infected ones. Furthermore, infected rats presented a significant delayed wound healing as measured by the histometric analysis (higher persistent polymorphonuclear infiltrate and lower density of newly formed bone). CONCLUSION: These findings indicate that rat sockets with experimentally induced infection produced higher levels of serum CRP, showing the potential of disseminated infection and a disturb in the alveolar repair process in an interesting experimental model for alveolitis studies.

Dry socket is one of the most studied complications in dentistry, and a great number of studies have searched for an effective and safe method for its prevention and treatment. One of the great clinical challenges since the first case was reported has been the inconsistency and differences in the various definitions of dry socket and the criteria used for diagnosis. The pathophysiology, etiology, prevention, and treatment of dry socket are very important in the practice of oral surgery. The aim of the present report was to review and discuss each aspect.

O cisto dentígero é o segundo cisto odontogênico mais frequente nos maxilares. São sempre radiolúcidos e mais comumente uniloculares.Geralmente são observados em exames de rotina ou quando do não irrompimento de um dente permanente. Os terceiros molares inferiores seguidos dos caninos superiores e ocasionalmente dentes supranumerários e odontomas podem estar envolvidos com a formaçãodo cisto dentígero, porém, sua etiopatogenia ainda não é totalmente conhecida. O cisto dentígero ocorre principalmente nas três primeiras décadas de vida, seu crescimento é lento e assintomático, contudo pode atingir dimensões consideráveis causando deformação facial, impactação e deslocamento de dentes e/ou estruturas adjacentes. A descompressão, marsupialização e a enucleação são as formas de tratamento mais empregadas, porém alguns critérios importantes devem ser considerados para o plano de tratamento como, tamanho do cisto, idade, proximidade com estruturas anatômicas e importância clínica do dente envolvido. Apesar das peculiaridades clínicas de cada caso e do método de tratamento escolhido, o prognóstico destas lesões é favorável.
The dentigerous cyst is the second most frequent odontogenic cyst in jaws. They are always radiolucent and commonly unilocular. They are usually found in routine exams or when a permanent tooth does not erupt. The third molars followed by maxillary canines and occasionally supernumerary teeth and odontomas may be involved with the formation of the dentigerous cyst, but its etiology is not yet completely known. The dentigerous cyst occurs mainly in the first three decades of life, and its growth is slow and asymptomatic, however, it may reach considerable dimensions causing facial deformity, impaction and displacement of teeth and/or adjacent structures. Decompression, marsupialization and enucleation are the most frequent forms of treatment used, nevertheless, some important criteria must be considered for the treatment plan such as cyst size, age, proximity to anatomical structures and clinical importance of the tooth involved. Despite the clinical peculiarities of each case and the treatment method chosen, prognosis of these lesions is favorable.
