Lately, it has been questioned whether localized juvenile periodontitis (LJP) is restricted to the permanent dentition, or if it sometimes might have a prepubertal onset, involving the primary dentition. To clarify this question, 17 patients with LJP, together with 17 non-LJP matched controls, were retrospectively examined for radiographic signs of alveolar bone destruction in their primary dentitions. All LJP subjects but one showed localized marginal bone loss, whereas no bone loss was observed among the controls. The results suggest that at least some cases of LJP start in the primary dentition prior to the involvement of the permanent teeth.
最近，有人质疑局限性青少年牙周炎（LJP）是否仅限于恒牙列，或者它有时是否可能在青春期前发病，累及乳牙列。为了澄清这个问题，对17例LJP患者以及17例匹配的非LJP对照进行了回顾性检查，以观察他们乳牙列中牙槽骨破坏的影像学征象。除1例患者外，所有LJP患者均表现为局限性边缘骨丧失，而对照组未观察到骨丧失。结果表明，至少部分LJP病例在恒牙受累之前就始于乳牙列。
