Abstract
As the minimally invasive approach against white spot like early caries lesions in proximal surfaces of the teeth, therapeutic sealing has been introduced and studied for effective materials and methods to arrest the early caries lesion effectively, which is still going on. This study was performed for the purpose of evaluating its validity for the non-cavitated lesions according to the depth from surface using therapeutic sealing followed by artificial caries induction and evaluation with micro-CT, and we obtained the results as follows. 1. It was revealed that the deeper the caries lesions are, the lower radiation intensity at lesion body areas in pre-treatment specimen. 2. In the sealed groups, there were no differences in radiation intensity between pre- and post-treatment, whereas there were significant decreases in unsealed groups(p<0.05). 3. Even in the specimens with the lesions reaching deeply into DEJ, the effect of sealing was significant(p<0.05). Conclusively, it was thought therapeutic sealing can be an effective tool against the early caries lesions, regardless of their depth into tooth, unless cavitated.
Key Words: Non-cavitated early caries lesion, Therapeutic sealing, Resin adhesive, Micro-CT, Radiation intensity
