Objective The purpose of this study was to compare different materials on alveolar ridge preservation of post-extraction sockets in anterior maxilla. Materials and method In this prospective, single center, randomized, controlled clinical trial, healthy patients who needed one single anterior maxillary tooth extraction (including bicuspids) were s...

For accurate repositioning of the maxilla in Le Fort I osteotomy, bone removal around the descending palatine neurovascular bundle and maxillary tuberosity is frequently required. Such task can be challenging due to the high vascularity of the region, which is the most common site of hemorrhage during removal of bony interferences. Although a rare...

Novas tecnologias vêm sendo aplicadas ao planejamento em reconstrução óssea para implantodontia, prova disso é a aplicação do fluxo digital e de novas técnicas reconstrutivas de menor morbidade, mais versáteis e de fácil execução. Este trabalho objetiva ilustrar o uso do planejamento reverso digital para o tratamento de um defeito ósseo horizontal...

Introduction: Assessment of two radiographic images reveals two distinct, extreme situations of physiological tooth resorption, characteristic of primary teeth with or without permanent successor, due to partial anodontia. Discussion: In all primary teeth, rhizolysis begins after the completion of formation, thanks to the apoptosis of their cell...

The oroantral communication is considered one of the most frequent complications in oral surgery, especially in extractions of posterior teeth in the maxilla, treatment of cystic lesions, neoplasms, osteomyelitis and trauma in the region of the maxillary sinus, forming fistulas. However, ectopic third molar and lesions such as odontomas are rarely...

Sialolithiasis is a common disease that affects the major salivary glands and can occur at any age. Parotid glands are rarely involved and, even rarer are the cases of sialoliths larger than 10 mm. This report presents the rare case of a giant parotid sialolith associated with facial cellulitis in a 75-year-old man. The treatment involved initially...

Maxillomandibular fixation in pediatric facial fractures is quite challenging to be achieved, especially in mid-mixed dentition. Traditional well established intermaxillary devices have a lot of limitations in these patients. This article presents a case of a 9-year-old female patient with a displaced mandibular fracture in which orthodontic button...

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.

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...

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 biol...

Resumo / Introdução / Radiografias panorâmicas são requeridas em grande escala como coadjuvantes no planejamento de tratamento ortodôntico. Esses exames comu-mente apresentam lesões assintomáticas que necessitam de acompanhamento e de tratamento específicos. Entre estes achados, podemos verificar com maior prevalência o cisto dentígero, o tumor odo...

Background: Unicystic ameloblastoma (UA) is a distinct variant of ameloblastoma displaying a large cystic cavity lining by ameloblastomatous epithelium and can present a wide variety of histologic patterns. Case report: We herein reported an unusual UA occurring in the mandible of a 23-year-old male patient who exhibited luminal, intraluminal an...

The pathogenesis of alveolitis is not well known and therefore experimental situations that mimic some features of this disease should be developed. 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. Non...

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 u...

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...

A 62-year-old man was referred for routine treatment of hyperplasia of the mucosa in the anterior lower jaw. An oroantral fistula was detected in the right superior alveolar ridge. The patient had no complaints. Plain radiographs showed a radiopaque foreign body in the posterior region associated with opacification of the maxillary sinus. Computed...

A 15-year-old white female sought our institution complaining of a chirping noise during speech and swallowing. The noise was spontaneous, perceptible, and enhanced when hard suction on the anterior palate was performed. The patient reported no trauma, infection, or other clinical feature related to the noise. Clinical examination showed 2 small gr...

Isotretinoin (13-cis-retinoic acid) is a retinoid that has been used for the past 20 years to treat a variety of dermatologic conditions. It is beneficial in many skin conditions, although its side effects and toxicity require careful monitoring by physicians and other health professionals, among them, dentists, who should be prepared to manage an...

INTRODUCTION: The cast surgery has great importance in orthognatic surgery treatment planning. AIM: In this article, a step by step lower model surgery will be presented, emphasizing important details and advantages of this procedure.
