정중과잉치와 제3대구치의 무기 분석을 통한 자가치아이식재로서의 가능성 평가

Abstract

Purpose : The aim is to evaluate of the potential of the mesiodens through the comparative inorganic analysis of 3rd molar teeth prior to clinical study. Material and methods : The extracted mesiodens and the 3rd molar teeth were prepared. The teeth are prepared as in the process of the autogenous tooth bone graft. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) analysis were performed for inorganic analysis. Results : Rough and porous surfaces were observed in all materials in SEM analysis. Ca/P ratio of mesiodens was 1.55 and the 3rd molar was 1.22 in EDS analysis. XRD analysis shows that the 3 main peaks position were similar. This means that the graft materials are very similar to that of the crystallinity. Conclusions : The mesiodens and the 3rd molar teeth are very similar to the inorganic component. These results provide reasonable rationale that mesiodens can be used as autogenous tooth bone graft in clinic.
