根尖囊肿是由感染根管内慢性炎症对根尖周组织的长期刺激,引起牙周剩余上皮的增生,中央部分液化而形成,是口腔颌面部囊肿中属于牙源性囊肿的一类,本身并非真正肿瘤。根尖囊肿是颌面部囊肿中较常见的一种。根尖囊肿到目前为止,绝大部分采用外科手术摘除,很少采用保守疗法。国内较早期有史俊南报导用根管治疗消除囊肿。国外曾报导观察了根尖囊肿经保守治疗后,囊肿上皮病理改变的变化情况。我们在1958年用氢氧离子(OH~-)电解治疗5例根尖囊肿,对其中4例作了定期追踪复查,其中1例作了10年远期效果观察。并于1974年对另外3例作了同样保守治疗。近、远期疗效都十分理想,囊肿消失
Apical cysts by the infection of chronic inflammation of the root canal periapical long-term stimulation of the tissue, causing residual periodontal epithelial hyperplasia, the central part of the formation of liquefaction, oral and maxillofacial cyst is a group of odontogenic cysts, It is not a real tumor in itself. Apical cyst is a more common type of maxillofacial cyst. Apical cyst So far, the vast majority of surgical removal, rarely using conservative treatment. Earlier Shi Junnan reported the use of root canal therapy to eliminate cysts. Foreign reports have observed the apical cysts by conservative treatment, the cyst epithelial pathological changes. In 1958, we treated 5 cases of apical cysts with hydroxide ion (OH ~ -) electrolysis, and 4 of them were followed up regularly. One of them had 10 years of long-term effect observation. In 1974, the same three conservative treatment was made. Near and long-term efficacy are very good, cysts disappear
