In 69 individuals from a randomized epidemiological material comprising 450 adults, an intra-individual comparison of the periodontal condition of 73 mesially tipped molars (30 degrees or more to a line perpendicular to the occlusal plane) and contralateral upright molars was made. The alveolar bone level mesially and distally of each tooth was registered in periapical radiographs. The occurrence of plaque, gingivitis and probeable pocket depths of 4 mm or more mesially and distally of each tooth was registered. No significant differences between tipped and upright molars could be found, regardless of the variable tested. The clinical implications of the findings are discussed from an orthodontic as well as a periodontal and prosthetic point of view.
在一个由450名成年人组成的随机流行病学资料中的69个人中，对73颗近中倾斜磨牙（与垂直于咬合平面的线成30度或更大角度）和对侧直立磨牙的牙周状况进行了个体内比较。在根尖片中记录每颗牙齿近中和远中的牙槽骨水平。记录每颗牙齿近中和远中牙菌斑、牙龈炎以及4mm或更深的可探牙周袋深度的发生情况。无论测试的变量如何，倾斜磨牙和直立磨牙之间均未发现显著差异。从正畸以及牙周和修复的角度讨论了这些发现的临床意义。
