ABSTRACT
A importância da permanência dos dentes naturais na cavidade bucal vem sendo cada dia mais reconhecida e almejada, seja pelo fator estético ou pelo funcional. Uma alternativa para a reabilitação de indivíduos com perdas dentárias ou exodontias indicadas é o transplante dental. Esta modalidade de tratamento corresponde à transferência de um órgão dental, para um alvéolo receptor. O presente trabalho relata e discute um caso de triplo transplante autógeno, utilizando terceiros molares, enfatizando as etapas cirúrgicas e demonstrando que após dois anos de preservação os resultados confirmam o sucesso deste tratamento. Anamnese, exames clínicos e radiográficos foram analisados de forma criteriosa, antes e após a cirurgia, sendo a radiografia panorâmica utilizada antes e após o ato cirúrgico e radiografias periapicais após, para acompanhamento individual das unidades transplantadas. Houve sucesso na realização dos transplantes dentários, obtendo regeneração pulpar e adaptação ao alvéolo receptor, mantendo o espaço dental com vitalidade e oclusão dentaria satisfatória. O procedimento apresentou sucesso significativo, obtendo êxito nas três unidades transplantadas, devolvendo o equilíbrio ao desenvolvimento crânio facial, comprovando sua eficácia na reabilitação oral em jovens com perdas prematuras de unidades dentárias...

The importance of the maintenance of natural teeth in the oral cavity has been increasingly recognized and desired, for the aesthetic and also the functional factor. An alternative for the rehabilitation of individuals with indicated tooth loss or extractions is dental transplantation. This type of treatment corresponds to the transfer of a dental organ to a recipient alveolar socket. The present work reports and discusses a case of triple autogenous transplantation, using third molars, emphasizing the surgical stages and demonstrating that after two years of preservation the results confirm the success of this treatment. Anamnesis, clinical and radiographic examinations were carefully analyzed, before and after surgery, with panoramic radiography used before and after surgery and periapical radiographs afterwards, for individual monitoring of transplanted units. Dental transplants were successful in achieving pulp regeneration and adaptation to the recipient alveolus, maintaining the dental space with vitality and satisfactory dental occlusion. The procedure was significantly successful, achieving success in the three transplanted units, restoring balance to the facial skull development, proving its effectiveness in oral rehabilitation in young people with premature loss of dental units...

OBJECTIVE: To verify the effectiveness of coconut water in preserving tissues for transplant. METHODS: Fifty male Wistar rats were randomly distributed in five groups, according to the following preservation solutions for tissue grafts: Group 1: Lactated Ringer; Group 2: Belzer solution; Group 3: mature coconut water; Group 4: green coconut water; Group 5: modified coconut water. In Group 5, the green coconut water has been modified like the Belzer solution. From each animal we harvasted the spleen, ovaries and skin of the back segment. These tissues were preserved for six hours in one of the solutions. Then, the grafts were reimplanted. The recovery of the function of the implanted tissues was assessed 90 days after surgery, by splenic scintigraphy and blood exame. The implanted tissues were collected for histopathological examination. RESULTS: The serum levels did not differ among groups, except for the animals in Group 5, which showed higher levels of IgG than Group 1, and differences in relation to FSH between groups 1 and 2 (p <0.001), 4 and 2 (p = 0.03) and 5 and 2 (p = 0.01). The splenic scintigraphy was not different between groups. The ovarian tissue was better preserved in mature coconut water (p <0.007). CONCLUSION: the coconut water-based solutions preserves spleen, ovary, and rat skin for six hours, maintaining their normal function.
OBJETIVO: Verificar a eficácia da água de coco na preservação de tecidos para transplante. MÉTODOS: cinquenta ratas Wistar foram distribuídas aleatoriamente em cinco grupos, de acordo com as seguintes soluções de preservação para enxertos teciduais: Grupo 1- Ringer lactato, Grupo 2- Solução de Belzer, Grupo 3- Água de coco maduro, Grupo 4- Água de coco verde, Grupo 5- Água de coco modificada. No Grupo 5, a água de coco verde foi modificada à semelhança da solução de Belzer. De cada animal, retirou-se o baço, os ovários e um segmento de pele do dorso. Esses tecidos foram preservados durante seis horas em uma das soluções. Em seguida, os enxertos foram reimplantados. A recuperação da função dos tecidos implantados foi avaliada 90 dias após a cirurgia, por meio de cintilografia esplênica, exames de sangue. Os tecidos implantados foram coletados para estudo anatomopatológico. RESULTADOS: as dosagens séricas não apresentaram diferença entre os cinco grupos, exceto pelos animais do Grupo 5, que apresentaram valores mais elevados de IgG do que o Grupo 1,e pelas diferenças em relação ao FSH entre os grupos 1 e 2 (p<0,001), 4 e 2 (p=0,03), 5 e 2 (p=0,01). A cintilografia esplênica não foi diferente entre os grupos. O tecido ovariano foi melhor preservado em água de coco maduro (p<0,007). CONCLUSÃO: as soluções à base de água de coco preservam baço, ovário e pele de rato durante seis horas, mantendo sua função normal.

PURPOSE: Autogenous transplantation of teeth can be defined as transplantation of teeth from one site to another in the same individual, involving transfer of impacted or erupted teeth into extraction sites or surgically prepared sockets". Successful autogenous transplantation of teeth depends upon a complex variety of factors. Such factors include damage to the periodontal ligament of the donor tooth, residual bone height of the recipient site, extra-oral time of tooth during surgery. Schwartz and Andreasen previously reported that autogenous transplantation of teeth with incomplete root formation demonstrated higher success rate than that of teeth with complete root formation. Gault and Mejare yielded similar rate of successful autogenous transplantation both in teeth with complete root formation and in teeth with incomplete root formation when appropriate cases were selected. This case report was aimed at the clinical and radiographic view in autogenous transplantation of teeth with complete root formation. MATERIALS AND METHODS: Patients who presented to the department of periodontics, Chonnam National University Hospital underwent autogenous transplantation of teeth. One patient had vertical root fracture in a upper right second molar and upper left third molar was transplanted. And another patient who needed orthodontic treatment had residual root due to caries on upper right first premolar. Upper right premolar was extracted and lower right second premolar was transplanted. Six months later, orthodontic force was applied. RESULTS: 7 months or 11/2 year later, each patient had clinically shallow pocket depth and normal tooth mobility. Root resorption and bone loss were not observed in radiograph and function was maintained successfully. CONCLUSION: Autogenous transplantation is considered as a predictive procedure when it is performed for the appropriate indication and when maintenance is achieved through regular radiographic taking and follow-up.
