Abstract: Objective: To compare the influence of two explorers on the enamel of artificial initial caries. Methods: Built an artificial initial caries model in vitro. Compared the influence of two explorers on the enamel of artificial initial caries. Results: 1.The holes probed by sharp explorer were deep and narrow. The holes probed by CPI explorer were shallow and wide. 2. The average strain energy produced by CPI explorer was larger than sharp explorer(Z=-2.021,P=0.043), But there was no significant difference because the strain energy produced by two explorers were in the same rate range. Conclusion: The damage on the enamel of artificial initial caries caused by sharp explorer is not larger than that caused by CPI explorer. So we suggest that the sharp explorer can still be used in sampling survey and clinical examination. But a gentle probing action is strongly recommended.
