The aim of this in vitro study was to evaluate and compare the dentinal tubule occlusion using nano-hydroxyapatite (n-HAP) containing toothpaste and mouthwash under a scanning electron microscope. The specimens were randomly divided into two groups with five specimens each: group 1-toothpaste group and group 2-mouthwash group. The percentage of the occluded dentinal tubules was assessed at the baseline, 7, 14, 21, and 28 days under a scanning electron microscope. The toothpaste group showed a higher percentage of occluded dentinal tubules as compared to the mouthwash group at the 7, 14, 21, and 28 days, respectively. It can be concluded that brushing twice daily with n-HAP containing toothpaste for duration of 28 days produced good dentinal tubule occlusion.
本体外研究的目的是在扫描电子显微镜下评估和比较使用含纳米羟基磷灰石（n-HAP）的牙膏和漱口水对牙本质小管的封闭情况。标本被随机分为两组，每组五个标本：第1组为牙膏组，第2组为漱口水组。在基线、第7、14、21和28天，通过扫描电子显微镜评估封闭的牙本质小管的百分比。在第7、14、21和28天，牙膏组封闭的牙本质小管百分比分别高于漱口水组。可以得出结论，每天用含n-HAP的牙膏刷牙两次，持续28天，可产生良好的牙本质小管封闭效果。
