RESUMO
O presente estudo avaliou, in vitro, as alterações térmicas na superfície externa radicular de dentes submetidos à instrumentação rotatória com quatro sistemas diferentes. Um total de 20 incisivos laterais superiores humanos foram divididos em 4 grupos e instrumentados com os sistemas ProFile, MicroMega, Quantec ou K3, sendo as variações térmicas da superfície radicular registradas por meio de 3 pares termoelétricos acoplados aos terços cervical, médio e apical das raízes dos dentes. Variações médias de temperatura não superiores a 0.4ºC ± 1.0ºC foram registradas (sistema ProFile), o que indica que estes instrumentos são seguros do ponto de vista biológico aos tecidos periodontais circunjacentes.
