Diagnóstico e planejamento em cirurgia parendodôntica: utilização da tomografia cone beam

The ability to tridimensionally evaluate pathological and anatomical areas, in apical surgery planning, presents a number of advantages. Cone beam computed tomography (CBCT) was developed for dental applications. This paper aims to present a literature review on CBCT, highlighting its advantages over both conventional computed tomography (CT) and radiography. Moreover, its clinical applications in apical surgery are discussed. LITERATURE REVIEW AND CONCLUSION: Unlikely CT, CBCT captures a volume of data in a single 360º rotation, providing benefits such as higher accuracy, better resolution, reduced scanning time and reduced radiation dose. In the maxillofacial region, CBCT has been mainly used in the assessment of dento-alveolar pathology and oral traumatology. CBCT provides a better diagnosis and quantitative information on periodontal bone levels than conventional radiography. It has also been used for patients requiring surgical facial reconstruction, orthognathic surgery, dental implants, and more complex tooth extractions. Besides that, it seems to be a significant tool in modern endodontic practice, presenting useful applications in apical surgery.

Estratégias de enfrentamento em crianças em situação pré-cirúrgica: relação com idade, sexo, experiência com cirurgia e estresse

This study's aim was to verify coping strategies among children aged between 7 and 12 years old who will be experiencing surgery and the potential relationship of coping strategies with sociodemographic variables, stress in children and in companions, and the child's prior experience with surgery. A total of 58 children hospitalized and waiting for elective surgeries responded to the Assessment Instrument of Coping to Hospitalization and an instrument to assess stress. The companion received a sociodemographic questionnaire and the Lipp Stress Symptom Inventory. Problem-solving strategies and distraction were the most frequent strategies used, while social withdrawal and opposition were the least frequent. Girls and children of stressful parents used emotion regulation strategies with significantly more frequency. Likewise, greater cognitive restructuring was observed in older children and those with prior experience with surgeries. The results show the need to consider the studied variables when developing pre-operative preparation programs.

Estudo comparativo entre traçados cefalométricos predictivo e pós operatório imediato de pacientes que foram submetidos à cirurgia ortognática para correção da síndrome da face longa

The aim of this research was to verify the accuracy of the prediction trace. Records in 15 patients admitted for orthognathic surgical treatment were analysed. Predictive and postoperative positíons of maxilla were compared with linear measurements. Statistically significant difference between predicted and postoperative position were demonstrated, but the prediction trace revealed to be very useful to help in decision of direction of movements, easy to do at low cost

Estudo da erupção dos dentes caninos, primeiros e segundos premolares dos lados direito e esquerdo, pelo método radiográfico

The tooth eruption have been studied for many years about the knowledge of its variations. From these variations the difference between the eruption of the superior and inferior archs, and also the right and left sides have been poorly analysed. The author compared the alveolar eruption of the permanents canines, first and second premolars between the right and left sides of the superior and inferior archs, from 7 and 11 years of age, in males and females, by radiographic method. By the Discipline of Radiology of the Diagnosis and surgery Departament of the School of Dentistry of São José dos Campos - UNESP, observed that: there is early eruption in female; the alveolar eruption sequence in maxillar and mandibular was: first premolar, second premolar e canino. There wasn't statiscally significant difference of the alveolar eruption between the right and left sides of maxillar and mandibular archs

Perfil clínico de crianças com indicação da cirurgia das tonsilas em um hospital terciário universitário

The indications for adenotonsillectomy in pediatric patients have changed considerably during the 90th decade. Local or systemic complications of the adenoid or tonsil hypertrophy itself have now been substituted by signs of obstructive ventilatory disturbances, including obstructive sleep apnea as the major indications for surgery. Objective: This study analyses the clinical profile of children submitted to adenotonsilectomy in their pre and postoperative state, at Botucatu Medical School-State University São Paulo, UNESP. Methods: 332 children of both genders, aged 1 to 12 years, who underwent adenotonsillectomy between 1999 and 2004, were studied, focused on epidemiological profile, pre and postoperative (1 month) symptoms, obtained from medical records. Height and weight were compared to brazilian normal age related values. Results: We found a predominance of the male gender, except in he group aged from 10 to 12 years. Considering wheight and height, we found important failure to thrive, mostly for height deficit. Among clinical aspects, we found a significant reduction in obstructive symptoms like snoring or apneia (p<0001) in the postoperative period. Conclusion: Our results were similar to the literature findings of patients clinical profile. The major indication for adenotonsillectomy in our service was clinical diagnosis of obstructive sleep apnea.

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.

Trauma traqueal associado à fratura mandibular: relato de caso

Introduction: The mandibular injuries account for about 20% to 50% of cases of facial fractures. Some consider the jaw the second most commonly fractured bone of the skull, and is the only mobile bone of the facial framework, which results in decreased stability compared to the trauma. When one takes into account the degree of airway obstruction in patients with facial fractures, the problem becomes much more serious since it is one of the most troubling complications of trauma. Objective: the relevance of the topic is aimed to report a case of a patient victim of mandibular fracture associated with trauma to the trachea. Case report: Case report: Patient 24 years old patient with tracheal trauma concomitant mandibular fracture surgically treated in conjunction with the thoracic surgeon. After 5 months postoperatively, the patient is in good condition general, no complaints. Final comments: This form is observed that the key to proper treatment of tracheal trauma associated with facial fractures is the knowledge of the type of injury, and an accurate diagnosis multidisciplinary.

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.

Reabsorção condilar progressiva: revisão de literatura

The progressive condylar resorption is a irreversible complication that can result in malocclusion and facial deformity that can happen especially in postoperative orthognathic surgery of mandibular advancement or combined surgery. Predominantly affect young women, bearers of malocclusions of skeletal class II and with incidence of temporomandibular disorders prior to surgical treatment. Its exact etiology and pathogenesis remain unclear. The purpose of this article is to make a literature review of the last 10 years on the progressive condylar resorption. For this, we used the Medline database for articles in the English language. Then, 13 articles were found, evaluated and compared on predisposing factors, etiology, diagnosis and clinical management.
