Frequency severity of gingival recessions was studied with Stahl and Morris indices. The results showed that the localization of gingival recession was more important on the mandible (37%) than on the maxillary (27.6%) it, also demonstrated the importance of various etiologies and particularly the association of trauma - tooth malposition (81%).
采用施塔尔指数和莫里斯指数对牙龈退缩的频率和严重程度进行了研究。结果表明，牙龈退缩在下颌骨（37%）的定位比在上颌骨（27.6%）更为重要，该研究还证明了各种病因的重要性，特别是创伤与牙齿错位关联（81%）的重要性。
