RESUMO
Para avaliar o desgaste interno do terço cervical de raízes de molares, comparando-se instrumentos rotatórios em níquel e titânio com oscilatórios em aço inoxidável e brocas Gates-Glidden, 30 raízes de molares humanos foram padronizadas e radiografadas. As radiografias foram digitalizadas e mediu-se a espessura dentinária na entrada do canal radicular e 3 mm abaixo da entrada, em relação à parede de risco e a de segurança. As amostras foram aleatoriamente divididas nos grupos G1 (Pré-Race), G2 (Gates-Glidden) e G3 (Endo-Eze). Radiografou-se novamente e as radiografias foram digitalizadas. Foi feita a redução percentual e os dados submetidos ao teste "t" pareado. Concluiu-se que não houve diferença significante entre os grupos, havendo, no entanto, um maior desgaste da parede de risco quando as brocas de Gates-Glidden foram utilizadas.
ABSTRACT
To evaluate the internal wear of the cervical third of molar root canal, comparing rotary nickel-titanium instruments with stainless steel oscillatory instruments and Gates-Glidden burs, 30 human molar roots were slandered and radiographed. The radiographs were digitalized and the dentin width was measured at the entrance of the root canal and 3 mm down from the entrance, in relation to the risk and safety walls. The samples were randomly divided the groups G1 (Pré-Race), G2 (Gales-Glidden) e G3 (Endo-Eze). Radiographs were taken again and digitalized. Percentual reduction made and the data were submitted to pared t test. It was concluded that there was no significant difference among the studied groups, thus a higher wear was found on the risk walls when Gates-Glidden burs were used.
