Abstract

Avulsion is caused by external forces and promotes a total exarticulation of the tooth from the alveolus. Tooth replantation is the treatment of choice to avoid tooth loss, however late replantation can result in inflammatory and/or replacement root resorption. In order to minimize the occurrence of root reabsorption after replantation, this study aims to evaluate the tissue repair process after late replantation, using the application of LLLT as surface treatment. Thirty rats will be randomly divided into 3 groups and they will have their upper right teeth extracted and maintained immersed in different storage media for 30 min, as follows: Control Group, teeth immersed in saline solution; LLLT Group, teeth immersed in saline solution and, after 30 min, the teeth will be treated with LLLT; Probiotic + LLLT Group, teeth immersed in probiotic and treated with LLLT; and Milk Group, teeth immersed in milk. Afterwards, the teeth will be replanted. After 60 days a histochemical analysis using Picrosirius red under polarized light microscopy for collagen fiber evaluation. Statistical analysis will be performed with a significance level of 5%. It is believed that the association of LLLT as root surface treatment obtains better results than milk in healing process of the periodontal ligament and pulp after late replantation. (AU)
