• 中文摘要： 年輕性牙周組織炎（juvenile periodontitis）在牙齒的支持構造（齒槽骨、牙周?帶等）所
  產生的破壞作用，近年來逐漸受到重視，但是關於這種疾病的研究報告卻不多見。尤其在中國人
  方面的文獻報告尚付厥如。此種疾病常潛伏發生於青春期階段，對牙周組織破壞力又比普通牙周
  組織炎大而快速，常造成牙齒病態移位、搖動，嚴重的威脅到正常的咬合機能。木報告對四名患
  有此種疾病的中國人作病史追查、血液、Ｘ光檢查及牙周粘膜骨膜瓣翻開手術治療，藉以明瞭年
  輕牙周組織炎的病史及臨床特徵，以求達到早期診斷和適當的治療。
  本研究發現：(1)病人接受檢查時均在二十歲左右，發病年齡都可追溯到青春期階段。(2)病人
  接受檢查時最常見的症狀是目鄰牙齒間失去接觸點、牙齒搖動或偏離齒列弓（病態移位的結果）
  和咀嚼無力。(3)牙齦有輕微發炎。經過較久的則伴有牙周膿腫。(4)邊緣牙齦上下的牙齒表面牙結
  石不多。(5)Ｘ光上可以看到牙間齒槽骨有斜角狀吸收（angular resorption）或甚至於有水平狀吸
  收（horizontal resorption）現象。(6)血液學檢查均居於正常值範圍內。(7)過去未有其他不良的
  全身性疾病病史。(8)牙齒咬合狀態參差不齊。(9)除了圍繞牙齒的齒槽骨破損厲害必需拔除的外，
  早期的牙周手術治療加上良好的口腔衛生習慣，可使本症獲得良好的控制。
  因此，詳細的追查病史、牙周組織和Ｘ光檢查對早期的診斷具有重要的價值，而早期的牙周
  手術及附帶的輔助治療，更是控制此症繼續進行不可缺少的方法。d
• 英文摘要： In recent years, Juvenile Periodontitis (Perio-dontosis) has been emphasized increasingly be-cause of its severe, intensive involvement of thedentition among adolescents and young adults. Four cases were thoroughly surveyed forthe exploring of the natural history, clinicalfeatures of Juvenile Periodontitis among Chinesepeople. As a beneficial aid leading to earlydiagnosis and treatment, detailed history of thepatients, periapical X-rays and basic hematolo-gical data were collected. Clinical examinationsincluding periodontal record of the pocketdepth, degree of gingival inflammation, plaqueand calculus index, caries, and state of occlusion,were also undertaken. From the present investigation, the fol-lowing findings were elicited: (1) Onset of thedisease could be traced to the circumpubertalperiod, although the clinical manifestations ap-peared near or over 20 years of age. (2) Themost strikingclinical features were loss of con-tact point between adjacent teeth and patholo-gical migration of the teeth, especially in an-terior teeth of both jaws. (3) No obvious localirritating factors commensurate with the severityof the disease could be found. (4) Most fre-quently, angular resorption or horizontal resorp-tion were noted particularly in themolar andincisor region. (5) There was no related historyof systemic diseases. Hematological data werewithin normal range. (6) Poor alignment ofteeth was existed in all of the present four cases. The periodontal treatment for the JuvenilePeriodontitis was mucoperiosteal flap operation,especially for the intrabony osseous defects.Early operation was highly recommended inthese cases. Other procedures, such as splintingof mobile teeth, occlusal adjustment, orthodonticcorrection, were important adjuncts for the ac-companied problems. The maintenance of ade-quate oral hygiene and restricted postoperativefollow-up were also an important contributionto the control of progression of the disease.
