ABSTRACT

Introdução - As suturas têm um papel importante na maioria das cirurgias, podendo influenciar grandemente no resultado clínico final. A escolha do fio de sutura constitui-se em um dos fundamentos para se obter a menor reação inflamatória tecidual quando do processo de reparação, já que alguns fios são considerados inertes, provocando menor reação do que outros. Materiais e Métodos - Foram utilizados quatro diferentes fios de sutura, a saber : seda, nylon, poliglactina 910 (Vicryl) e politetrafluoretileno expandido (e-PTFE). Os fios de sutura foram colocados em gengivas humanas as quais seriam submetidas a cirurgias pré-protéticas. Após sete dias, o tecido gengival foi excisado e processado histologicamente para observação em microscopia óptica. Resultados e Conclusão - Os resultados permitiram chegar à conclusão que o fio que promoveu menor reação foi o de poliglactina, seguido pelos de e-PTFE e nylon, culminando com a seda que provocou maior inflamação.


Introduction - The sutures play an important role in most of the surgeries, and may greatly influence the final clinical result. The choice of the suture material consists of one of the basis to obtain the least tissular inflammatory reaction at the time of healing process, since some materials are considered inert promoting less reaction than others. Materials and Method - It was evaluated the gingival reaction using four different suture materials such as: silk, nylon, polyglactin 910 (Vicryl) and expanded polytetrafluorethylene (e-PTFE). The suture materials were placed in human gingiva that would be to preprosthetics surgeries. After seven days, the gingival tissue was excised and histologically processed for optical microscopy. Results and Conclusion - The results show that the suture which promoted the least reaction was the polyglactin, followed by e-PTFE, nylon and silk which promoted the highest inflammation.
