临床上常可见到一些做过牙髓治疗的牙齿又出现牙髓炎的症状、经过牙髓炎诊断方法检查并除去原充填物探查根髓诊断为残髓炎。为提高对本病的识别与治疗,我们为此分析讨论如下: 结果 1.患牙检查:全部患牙银汞充填体完好,患牙叩诊时多数病人轻度痛或不适,少数病人表现为叩后明显或无叩痛,温度测验多数病人对温度刺激反应不强烈,但也有敏感性升高或降低或无反应者。 2.髓腔根管情况:去除原充填物显露髓腔根管内均有探痛的根髓存在,但探痛深度各异,多数在根中1/2或根尖1/3处。 3.发病时间:残髓炎发病距上次牙髓治疗时间间隔长短不一,差别比较大,最短即可出现,最长可达十几年之久。
Clinically often seen some of the teeth have done pulp treatment of pulpitis symptoms appear after the diagnosis of pulpitis to check and remove the original filling to explore the diagnosis of medulla oblongelitis. To improve the identification and treatment of this disease, we analyze the following for this analysis: Results 1. Tooth examination: All teeth amalgam filling intact, most patients with dental percussion mild pain or discomfort, a small number of patients showed knock After the obvious or no percussion pain, temperature test most patients respond to temperature stimulation is not strong, but there are also sensitivities increased or decreased or no response. 2. Medullary canal root canal situation: Remove the original filling medullary canal root canal presence of pain-rooted medulla there, but the depth of different analgesic pain, most in the root 1/2 or apical 1/3. 3. Incidence: the incidence of residual pulpitis last dental pulp treatment interval varies, the difference is relatively large, the shortest can occur, the longest up to more than 10 years.
