Estudo comparativo da inclinação do plano oclusal de modelos para cirurgia ortognática montados em dois tipos de articuladores semi-ajustáveis

Purpose: The aim of this study was to compare occlusal plane angulation measured in two different types of semi-adjustable articulators with that obtained on the lateral cephalometric radiograph. Materials and Methods: 20 patients due to undergo orthognathic surgery had dental casts mounted in two different types of semi-adjustable articulators through face bow transfer from the position of the maxilla and occlusal recording to the mandible. After mounting, the inclination of the occlusal plane in the articulators was measured and compared with the inclination measured at on both articulators and compared with the inclination measured on the lateral cephalometric radiographs and between the articulators themselves. The results obtained werestatistically analyzed. Results: Mean angulation values for the Bio Art (7.55º) and Kavo (-5.70º) articulators differ by 13.25º, which is statistically significant (p=0.00). When individually compared to the lateral cephalometric radiograph (5.075º), the Bio Art articulator showed more similar angulation values, with a difference of 2.475º, while the Kavo articulator presented a difference of 10.775º. Conclusion: Neither of the models of semi-adjustable articulators accurately reproduced the inclination of the maxillary occlusal plane of patients with dentofacial deformities; the difference between the two articulators tested and the lateral cephalometric radiograph was lower for the Bio Art than for the Kavo articulator.

Cirurgia estética para remoção de hiperplasia gengiva: granuloma piogênico

The pyogenic granuloma, a lesion considered hyperplastic regenerative inflammatory reaction is a finding commonly found in the oral cavity, affecting large numbers of individuals, being more prevalent in females. But its pathogenesis is not well defined and may be associated with numerous factors that stimulate tissue proliferation. Correct diagnosis and treatment plan are essential for success in approach, restoring function and aesthetics to the periodontal tissues. In agreement with the literature, the most common treatment and greater predictability is surgical removal, which involves resection of the lesion, together with its base inserted into the underlying tissue, periosteum and bone tissue. However, the excision can promote aesthetic defects, particularly in anterior regions where it is most affected. This article reports on the importance of a correct surgical approach for removal of pyogenic granuloma in the region of the interdental papilla between teeth 42 and 43, resulting in a good anatomical result and aesthetic.

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 estabilidade da cirurgia do tipo sagital da mandíbula com vista a correção de deformidades faciais

This research evaluated the surgical stabilily in patients with mandibular prognathism and retrognathism in which was used sagital split technic to correct those detormities. Twelve patients were selected from the clinic of only one experienced surgeon. Six patients presenter a Class III 6 a Class II molar relationship. A comparative cefalometric analysis using linear and angular measurements was performed of pre-surgery, imediate pós-surgery and 1 year follow-up. The following conclusions were obtained. 1 The Dal Pont sagital split technic modified by Epker to correct mandibular prognathisn and retroghnatism is a stable technic and must be indicated to correct those deformities. 2 Small relapses are easily corrected by the post-surgical orthodontic treatment. 3 A small over correction is advised in cases of large mandibular advancements or set bascks. 4 In those cases which a large amount of mandibular retrusion on advancement need to be performed, a combination of maxillary and mandibular surgery should be used. Rigid fixation technic is also indicated in those cases

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.

Melanoma subungueal in situ tratado com cirurgia funcional

Melanoma subungueal in situ tratado com cirurgia funcionalHamilton Ometto StolfI, Hélio Amante MiotI, Nilton de Ávila ReisIIDepartamento de Dermatologia e Radioterapia, Universidade Estadual Paulista (Unesp)INTRODUÇÃOO melanoma subungueal representa aproximadamente 2% a 3% dos melanomas cutâneos em pacientes caucasianos1 e 20% em pacientes negros2 ou asiáticos.3A exposição solar, tida com principal fator de risco para o melanoma cutâneo,4 parece desempenhar papel secundário no desenvolvimento da variante subungueal,5 uma vez que a radiação ultravioleta dificilmente penetra no leito ungueal. Além disso, nevos subungueais como lesões precursoras são extremamente raros.6Os polegares e háluces são os mais acometidos, sendo o polegar responsável por 56% dos casos entre todos os dedos e o hálux por 86% dos dedos dos pés.7A confirmação do diagnóstico é feita a partir do exame anatomopatológico da lesão, geralmente localizada na matriz ou leito ungueal. A verificação histológica do melanoma subungueal é frequentemente postergada por conta do atraso no diagnóstico clínico,8-10 gerando piora do prognóstico.O prognóstico geralmente é ruim: as taxas de sobrevida real de cinco anos variam entre 16% a 20%, podendo atingir até 80% se consideradas taxas de sobrevida estimada.2,3,11-18RELATO DE CASOPaciente de 44 anos, do sexo feminino, professora, com queixa de aparecimento de mancha na unha do hálux direito há cinco anos. Relata aumento progressivo lento na largura da faixa. Ao exame dermatológico, apresentava faixa de melanoníquia extensa, irregular, bordas mal definidas e estria de pigmentação mais acentuada em uma das margens do leito ungueal do hálux direito (Figura 1). Exame dermatoscópico (aparelho Dermalite II Pro, aumento de 10 vezes) confirmou faixas irregulares e cores variadas de hiperpigmentação.Foi realizada a avulsão parcial da lâmina ungueal e incisão na prega ungueal lateral para visualização do local da origem da pigmentação no leito ungueal,
