摘要 一、临床资料患者,男性,29岁,飞行员。2017年5月在原空军青岛航空医学鉴定训练中心行年度体检。自诉右侧后牙自发性痛,伴右侧头疼3 d。检查:46牙合面龋洞深,大量黑褐色腐质,探及露髓点,疼痛明显,叩诊(-),牙龈未见异常,牙体无松动,冷诊(+)。X线示:46牙齲损低密度影已达髓腔,根尖区未见明显异常。诊断:46牙急性牙髓炎。治疗:考虑到飞行员疗养时长有限,决定行46牙橡皮障下一次性根管治疗+全冠修复。处置:46牙局麻后上橡皮障,开髓、揭顶,口腔显微镜下探查根管,可及近中颊、近中舌、近中中间根管和偏颊侧的远中根,同时在舌侧髓壁较高位置上发现一细小根管口,探查后发现其与远中颊根管走向分叉较大,弯曲且长度较短,故怀疑存在远舌根,即第5根管。根测后机用马达根备至F2(06锥度),大锥度牙胶尖试主尖且多角度拍根尖X线片核实工作长度,热熔牙胶根充,磷酸锌垫底,P60树脂充填。5 d后复诊,自诉无明显不适。备牙、取模及咬合关系、比色、戴临时冠。7 d后永久粘固全冠。截止笔者发稿前共随访两年,该飞行员日常及飞行期间无任何不适。
