RESUMO
Facial trauma can be considered one of the most serious aggressions found in the medical centers due to the emotional consequences and the possibility of deformity. In craniofacial surgery, the use of autologous bone is still the first choice for reconstructing bony defects or irregularities. When there is a shortage of donor bone or a patient refuses an intracranial operation, alloplastic materials such as polymethylmethacrylate (PMMA) can be used. The PMMA prosthesis can be pre-fabricated, bringing advantages such as reduction of surgical time, easy technical handling and good esthetic results. This paper describes the procedures for rehabilitating a patient with PMMA implants in the region of the face, recovering the facial contours and esthetics of the patient.

Furcal perforations may occur during access opening of the pulp chamber or cavity preparation. The perforation can cause an inflammatory reaction in the periodontal ligament. Management of these iatrogenic accidents can pose a significant clinical challenge, mainly when they occur in primary teeth. Current developments in the techniques and materials utilized for root perforation repair have enhanced this procedure's prognosis. Recently, mineral trioxide aggregate (MTA) has been used for several dental purposes. This biocompatible material promotes bone healing and elimination of clinical symptoms. The purpose of this case report was to describe the treatment of a furcal perforation using mineral trioxide aggregate (MTA) in a primary molar tooth. After 20 months, the tooth was asymptomatic. The radiolucent image had disappeared and bone formation at the furcation area had been observed, suggesting healing of the underlying periodontal tissues. Therefore, MTA may be considered an alternative option for the repair of furcal perforation in primary teeth, prolonging the longevity of these dental elements.

The treatment of a large dentine caries, which seemed to be a small pit-and-fissure carious lesion on the occlusal surface of the permanent mandibular right first molar in a 6-year-old boy, is presented. The treatment included the filling of the root canals and the sealing of the cavity with composite resin. Underlying periodontal tissue healing could be radiographically observed at the 14-month follow-up. It is possible that a better visual examination, with careful cleaning and drying of teeth, may improve occlusal caries detection. Dentists should examine bitewing radiographies carefully for occlusal demineralization. As radiographies are probably an effective method of lesions caries diagnosis, they should be recommended at appropriate ages to aid early detection of these lesions.
O tratamento de uma cárie grande do dentine, que pareça ser um lesion carious do poço-e-pit-and-fissure pequeno na superfície occlusal do primeiro molar da direita mandibular permanente em um menino de 6-year-old, é apresentado. O tratamento inclui o enchimento dos canais da raiz e do sealing da cavidade com resina composta. O tecido peridental subjacente que healing podia radiographically ser observado na continuação de 14 mês. É possível que uma examinação visual melhor, com limpeza cuidadosa e secagem dos dentes, pode melhorar a deteção occlusal da cárie. Os dentistas devem examinar radiographies do bitewing com cuidado para o demineralization occlusal. Porque as radiografias são provavelmente um método eficaz do diagnóstico da cárie dos lesions, devem ser recomendados em idades apropriadas ajudar à deteção adiantada desta lesão.
