Of 49,380 male naval recruits who were screened for juvenile periodontitis (JP), 270 were clinically diagnosed as having the disease. Full-mouth radiographs identified 182 of these 270 patients as having JP with extensive bone loss on permanent first molars and/or incisors. These 182 patients, 137 (75.3%) of whom were black, were further classified into Type I: bone loss involving first molars and/or incisors and up to two additional teeth; Type II: involvement of first molars/incisors and several additional teeth; and Type III: generalized involvement (more than 14 teeth) but with bone loss notably more extensive on the first molars and/or incisors. Of the 182 patients, 129 (70.9%) were Type I; 43 (23.6%) were Type II, and 10 (5.5%) were Type III. The molars were involved more frequently than the incisors; more than one molar was always involved, with or without incisor involvement. Most cases had minimal or no radiographic caries, and 46% had demonstrable calculus. Of the remaining 88 cases from the 270 with the initial diagnosis of JP, 63 demonstrated severe bone loss on more than 14 teeth, with many of the teeth being involved to the same degree. These cases were termed rapidly progressive periodontitis. Six of the 88 cases had bone loss on only one tooth surface of the dentition. These cases were termed acute localized destruction of alveolar bone. The status of the other 19 cases could not be determined.
在49380名接受青少年牙周炎（JP）筛查的男性海军新兵中，有270人被临床诊断患有该疾病。全口X光片显示，这270名患者中有182人患有青少年牙周炎，其恒上第一磨牙和/或切牙有广泛的骨质流失。这182名患者中，137人（75.3%）为黑人，他们被进一步分为：I型：骨质流失累及第一磨牙和/或切牙以及另外至多两颗牙齿；II型：累及第一磨牙/切牙和几颗其他牙齿；III型：广泛累及（超过14颗牙齿），但第一磨牙和/或切牙的骨质流失明显更广泛。在这182名患者中，129人（70.9%）为I型；43人（23.6%）为II型，10人（5.5%）为III型。磨牙比切牙更常受累；总是有一颗以上的磨牙受累，无论切牙是否受累。大多数病例的X光片显示龋齿极少或无龋齿，46%的病例有明显的牙结石。在最初诊断为青少年牙周炎的270例患者中，其余88例中，63例显示超过14颗牙齿有严重骨质流失，许多牙齿受累程度相同。这些病例被称为快速进展性牙周炎。88例中有6例仅在牙列的一个牙面有骨质流失。这些病例被称为牙槽骨急性局限性破坏。另外19例的情况无法确定。
