RESUMO
A disostose cleidocraniana (DCC) foi descrita e conceituada, pela primeira vez, em 1897, por Marie e Sainton. O padrão de herança é autossômico dominante, porém, em alguns casos, interferências externas no período fetal poderiam causar mutações genéticas, impedindo a transformação de células-tronco mesenquimais em osteoblastos. Essa patologia é caracterizada por malformações cranianas, anormalidades nas clavículas, dentes supranumerários e retenções dentárias. Estudos radiológicos e genéticos são extremamente importantes para o seu diagnóstico preciso. O presente trabalho objetiva apresentar um tratamento cirúrgico dentário em paciente portador dessa patologia.
The Cleidocranial dysostosis (CCD) was described and conceptualized for the first time in 1897 by Marie and Sainton. The pattern of in heritance is autosomal dominant but, in some cases, externalinterference in the fetal period could cause genetic mutation preventing the transformation of mesenchymal stem cells into osteoblasts. This pathologyis characterized by cranial malformations, abnormalities of the clavicles, supernumerary teeth and dental retentions. Radiologicalstudies are extremelyimportanttoa precise diagnosis. Thisstudy aims to present a dental surgicaltreatment in patientswiththispathology.

INTRODUCTION: Surgically assisted maxillary expansion (SAME) is used to treat transverse maxillary discrepancies. The effect of this technique on the nasal airway has been the subject of a large number of studies. OBJECTIVE: The aim of the present study was to identify changes in the nasal airway in patients having undergone SAME. MATERIALS AND METHODS: A prospective study was carried out on a sample of 10 patients having undergone SAME who agreed to participate in all phases of the study. Data acquisition involved a questionnaire, Glatzel mirror, and computed tomography measurements in both the preoperative and postoperative periods. RESULTS: Nasal width increased in all patients following SAME (mean increase: 1.29 mm). The mean opening of the intermaxillary space was 5.30 mm. The postoperative nasal airway was larger in 8 patients (80%), with a mean increase of 0.30 cm(2) (18.52%). A significant overall increase (P < 0.05) in the nasal valve angle occurred in the postoperative period. The use of the Glatzel mirror revealed a smaller area of condensation in the postoperative period in only 1 patient. CONCLUSIONS: The nasal airway underwent a positive change following surgically assisted maxillary expansion. Moreover, the nasal valve angle is suggested as a new parameter for the analysis of this improvement.

Sialolithiasis is a benign pathology that occurs most frequently in the submandibular salivary gland due to its anatomic features. Depending on the size and degree of calcification, a sialolith can be visible in radiographic examinations. Patients commonly experience pain and/or edema when the ducts are obstructed. The authors report two cases of sialolithiasis of the submandibular gland after searching for the source of swelling in the submandibular region. The diagnosis was confirmed by clinical and tomographic examinations. Despite the considerable size of the sialoliths, treatment consisted of the removal of the calcified mass using an intraoral surgical approach. The prognosis is often good and there is generally no recurrence of the condition.

The aim of the present study was to assess the clinical and radiographic repercussions of surgically assisted maxillary expansion on the septum, nasal cavity and nasal conchae. The sample was made up of 15 patients with skeletal maturity (9 females and 6 males between 16 and 45 years of age) and maxillary transverse deficiency. Assessments were performed through anterior rhinoscopy and frontal cephalometric radiographs on three occasions: (T0) preoperative period, (T1) locking of the expander and (T2) six months following the locking procedure. An increase was observed in the basal portion of the pyriform aperture and distances between the lateral wall of the basal portion of the pyriform aperture and the septum. The radiographic exam revealed that the nasal septum did not undergo any statistically significant change in its position. Moreover, no significant changes in the position of the nasal septum or nasal conchae were detected throughout the three evaluation times. The results suggest that surgically assisted maxillary expansion is capable of widening the basal portion of the pyriform aperture, with little repercussion on the anterior position of the nasal septum and inferior nasal conchae.

Na maxila, a dimensão transversal é a que menos cresce, podendo ocasionar uma deficiência transversal maxilar. A correta correção dessas deformidades em pacientes adultos, para alcançar uma oclusão funcional estável, muitas vezes, se faz necessária uma expansão maxilar cirurgicamente assistida, na qual consiste basicamente em um procedimento auxiliar, com o objetivo de liberar as áreas de maior resistência maxilares, por meio de osteotomias, permitindo, assim, a obtenção de uma expansão maxilar satisfatória. Diante do exposto, o presente estudo tem como objetivo avaliar clinicamente os resultados obtidos em uma série de casos de pacientes submetidos à expansão maxilar cirurgicamente assistida e discutir sobre a literatura vigente.
The maxillary transverse dimension is the least that grows, can cause a maxillary transverse deficiency. The surgically assisted maxillary expansion (SAME) it is often necessary in adult patients, to achieve a stable and functional occlusion. SAME consists of a procedure to assist for release the greatest resistance maxillary region through osteotomies, thus obtaining the maxillary expansion satisfactorily. The aim of this study is evaluate the results of patients who have undergone maxillary expansion assisted surgery and discuss the current literature.
RESUMO
A ocorrência de caninos inclusos é uma condição comum na população que procura tratamento ortodôntico e a excelência da terapia ortodôntico-cirúrgica traduz-se na correção da oclusão, harmonia do sorriso, saúde periodontal, manutenção da saúde pulpar e estabilidade pós-tratamento. Para obtenção de tais condições, ressalta-se a importância de um trabalho multidisciplinar. O presente trabalho objetiva abordar os aspectos clínicos e radiográficos dos caninos inclusos submetidos à tratamento orto-cirúrgico. O estudo foi realizado na Faculdade de Odontologia de Pernambuco (FOP-UPE) no período de 2000 a 2007. Realizou-se uma avaliação clínica (cor, forma da gengiva, posição no arco) e radiográfica, (dilaceração, lâmina dura, presença de processo periapical). Como resultado, observamos que 4 pacientes (23,5%) apresentaram retração gengival com hipersensibilidade associada, apenas um paciente (6,25%) apresentou mobilidade dentária, nenhum dos dentes examinados apresentou alteração de forma e do total 14 dentes (82,35%) responderam positivamente ao teste de vitalidade pulpar. A avaliação Radiográfica foi realizada em 14 dentes, destes 07 (50%) apresentaram dilaceração radicular, 04 dentes (28,60%) estavam relacionados à odontomas, 02 dentes (14,28%) apresentaram reabsorção da crista óssea alveolar, 02 dentes (14,28%) mostraram calcificação intracanal. Tracionamento ortodôntico na amostra estudada aparece como um procedimento eficaz, seguro e reprodutível.
The occurrence of impacted canine is a common condition in the population who seeks orthodontic therapy and the excellence in orthodontic- surgical treatment leads to the correction of the occlusion, smile harmony, periodontal health, maintenance and stability of pulp tissue. To obtain these conditions, the study highlights the importance of a multidisciplinary work. This paper aim to address the clinical and radiographic findings of impacted canines who underwent ortho-surgical treatment. The study was conducted at the Faculty of Dentistry of Pernambuco (FOP-UPE) in the period of 2000 to 2007. Clinical parameters (color, gingiva aspect, arch position) and radiographic features (dilacerations, periapical inflammation) were observed. As a result, four patients (23.5%) had gingival recession associated with hypersensitivity, only one patient (6.25%) had tooth mobility, none of the teeth examined showed a change of form and 14 teeth (82.35 %) responded positively to vitality test. Radiographic evaluation was performed in 14 teeth, 07 of these (50%) had root dilaceration , 04 teeth (28.60%) were related to odontomas, 02 teeth (14.28%) had resorption of alveolar bone crest, 02 teeth ( 14.28%) showed intracanal calcification. Ortho-surgical treatment appears to be a safe, efficient and reproducible.
RESUMO
UNLABELLED: Surgical access to the skull base is always difficult, especially because of the noble anatomic structures present there. Maxillary osteotomy provides direct view to the clivus region and the neck spine, and it also bears less morbidity when compared to the many other accesses described in the literature. AIM: to assess 11 patients submitted to transmaxillary osteotomy, describing the surgical technique and postoperative results and complications. MATERIALS AND METHODS: A retrospective study involving eleven patients submitted to transmaxillary approach to the brainstem. We studied dental occlusion, trans and postoperative bleeding, bone necrosis and soft tissue alterations. All followed the same surgical protocol and were followed up for two years. RESULTS: after treatment, all the patients improved in their clinical status and had no neurological complication, trans and postoperative hemorrhage or major complications were seen. Among the complications, two patients had incomplete maxilla fracture, two had laceration of their nasal mucosa and one had, as late complication, an oral-sinusal fistula. CONCLUSION: Transmaxillary osteotomy provided proper access to the clivus for brainstem decompression with low rate of complications in this series.

OBJECTIVE: Clinicians often assume that changes following orthognathic surgery are both physically and psychologically beneficial to the patient. The present study investigates patient perception regarding improvement after surgically assisted rapid maxillary expansion. STUDY DESIGN: A survey with twenty-three patients was carried out to identify satisfaction with the surgical outcome and assess whether the surgery met patient expectations. General information was also collected on schooling, age, gender, chief complaint and reasons for seeking treatment. RESULTS: Most patients (n = 19; 82%) were advised to undergo surgery by a dentist. Twenty-two (95%) patients reported being satisfied with the operation procedure. Twenty-one (91%) patients reported that the procedure met their expectations. Nineteen respondents would undergo the same operation again and would recommend treatment to others with similar problems. CONCLUSION: The need for surgery associated with orthodontic appliances to correct a transverse maxillary deficiency requires a proper explanation to patients regarding the procedure and postoperative period in order to ensure realistic expectations concerning the surgical goals.

O acesso cirúrgico à região de base do crânio é sempre difícil principalmente pelas estruturas anatômicas nobres associadas. A osteotomia maxilar proporciona visão direta à região de clivus e coluna cervical, além de apresentar uma menor morbidade em relação aos diversos acessos descritos na literatura. OBJETIVO: Avaliar 11 casos submetidos à osteotomia transmaxilar, descrevendo técnica cirúrgica, resultados e complicações pós-operatórias. PACIENTES E MÉTODOS: O estudo retrospectivo de onze pacientes foi submetido à cirurgia transmaxilar para acesso à região do tronco encefálico. Registros quanto à oclusão dentária, hemorragia trans e pós-operatória, necrose óssea e alterações de tecido mole foram estudados. Todos seguiram o mesmo protocolo cirúrgico e acompanhamento médio de dois anos. RESULTADOS: Após o tratamento todos os pacientes apresentaram melhora do quadro clínico e nenhum dano neurológico, hemorragia trans e pós-operatória ou intercorrências maiores foram identificadas. Dentre as complicações, em dois pacientes ocorreu fratura incompleta da maxila, dois apresentaram laceração da mucosa nasal e um apresentou como complicação tardia uma fístula bucossinusal. CONCLUSÃO: A osteotomia transmaxilar possibilitou adequado acesso a região de clivus para descompressão do tronco encefálico com baixo índice de complicações nesta série de casos.
