| Research Abstract |
In conservative tooth procedure, removing caries lesion or deteriorated gutta-percha in contaminated root canals are often required. Today, treatments involving minimal intervention are generally preferred. Various alternatives, including air-abrasive and laser technologies, are studied in order for the purpose of preserving normal dentine structure.
In this study, the possibility that the use of water-jet technology might be expanded to accomplish the selective removal of caries lesion and of root canal filling materials was examined. The hardness of artificial caries-like lesion and of gutta-percha deteriorated were measured. The trial machine of water-jet was made, and examined the efficacy of removal artificial caries-like lesion and of degenerated gutta-percha.
