目的:评估各种牙间清洁助剂在不同的植入物支撑牙冠设计上对人工生物膜去除的功效。
方法:制造了第一磨牙缺失的下颌模型,并安装了单植入物类似物,并装载了不同设计的牙冠(凹形,直,和凸)。用封闭喷雾制备人工生物膜。30名志愿者(牙周病医生,牙科保健员,和外行人)被要求清洁邻间区域。牙冠被拧开并在标准化的环境中拍照。通过清洁比率测量结果,该清洁比率表示清洁表面相对于测试表面的面积。
结果:所有工具都清洁了基底表面上有利于凹冠(p<.001)的显着差异,除了水牙线。有证据表明“清洁工具”的整体效果,“\”表面,“和”皇冠设计“(p<.0001),“参与者”因素除外。每个清洁工具和整体组合表面的平均清洁比率为(以%计):牙线:43.02±23.93,超级牙线:42.51±25.92,电动间隙刷:36.21±18.78,齿间刷:29.10±15.95,和电动水牙线:9.72±8.14。牙线和超级牙线在去除牙菌斑方面明显优于其他工具(p<.05)。
结论:凹冠轮廓具有最大的人工生物膜去除能力,然后是基底表面的直冠和凸冠。牙线和超级牙线是去除人工生物膜最有效的齿间清洁装置。所测试的清洁装置中没有一个能够从邻间/基底表面完全去除人造生物膜。
OBJECTIVE: To evaluate the efficacy of various interdental cleaning aids for artificial biofilm removal on different implant-supported crown designs.
METHODS: Mandibular models with missing first molar were fabricated and installed with single implant analogs and loaded with crowns of different designs (concave, straight, and convex). Artificial biofilm was made with occlusion spray. Thirty volunteers (periodontists, dental hygienists, and laypersons) were asked to clean the interproximal areas. The crowns were unscrewed and photographed in a standardized setting. The outcome was measured by the cleaning ratio which represents the cleaned surfaces in relation to the area of the tested surface.
RESULTS: A significant difference in favor of concave crown (p < .001) on the basal surface was cleaned by all tools, except the water flosser. There was evidence of an overall effect of \"cleaning tool,\" \"surface,\" and \"crown design\" (p < .0001) except for the \"participant\" factor. The mean cleaning ratio for each cleaning tool and overall combined surfaces were (in%): dental floss: 43.02 ± 23.93, superfloss: 42.51 ± 25.92, electric interspace brush: 36.21 ± 18.78, interdental brush: 29.10 ± 15.95, and electric water flosser: 9.72 ± 8.14. Dental floss and superfloss were significantly better (p < .05) than other tools in removing plaque.
CONCLUSIONS: Concave crown contour had the greatest artificial biofilm removal, followed by straight and convex crowns at the basal surface. Dental floss and superfloss were the most effective interdental cleaning devices for artificial biofilm removal. None of the tested cleaning devices were able to completely remove the artificial biofilm from the interproximal/basal surfaces.
