【一般资料】

患者男,30岁

【主诉】

因右上后牙旧充填材料松动2d来我科就诊。

【现病史】

患者1年前,右上颌后牙因龋损于他院行“充填治疗”,具体不详。2d前,右上颌后牙充填物松动,现因影响咀嚼要求治疗。

【体格检查】

6近中牙合面可见白色树脂充填材料,材料表面可见金属固位环,充填材料松动,悬凸明显。探痛(一),牙髓活力测试无反应,叩痛(一),牙齿不松动。牙周探诊出血(+),未探及深牙周袋。

【辅助检查】

x线片可见6近中低密度影,金属固位环位于其中,根尖周小面积暗影,疑似4个独立根影像(图1)。

【初步诊断

诊断为6慢性根尖周炎。

【治疗】

拟行根管治疗术后进行全冠修复。初诊治疗过程如下:局麻下放置橡皮障,去除旧充填物,取出金属固位环。开髓,髓腔异味明显,无成型牙髓,揭全髓室顶,开髓洞型为方圆形。显微镜下探查,可见4个根管口。镜下可见髓室底中央牙本质形成移行性凹陷(图2)。10号K锉探查,工作长度为12mm。电子根测仪显示器械到达牙周膜。提示该牙副根管存在。采用小号K锉探查根管,颊侧双根初锉为10号,腭侧双根初锉为15号,测量工作长度[近中颊根管(MB)18mm、远中颊根管(DB)19mm、近中腭根管(MP)21.5mm、远中腭根管(DP)20.5mm]。拍摄根尖片,确认工作长度(图3)。鉴于该牙解剖结构较复杂,为避免遗漏根管,封CP棉球后进行CBCT检查,CT结果确认该牙为4牙根4个根管(图4为牙根水平截面),MB2影像不清晰(图5示近中双根,图6示远中双根),同时CBCT影像发现劁牙颈部偏颊侧有一球形的釉质凸起(图5)。1周后复诊,患者未诉疼痛不适。局部检查患牙叩痛(一),不松,牙龈未见明显红肿。橡皮障保护下去掉暂封,冲洗髓腔后,采用ProTaper镍钛器械+ED.TA预备MB、DB至F2,DP和MP至F3,预备副根管至F1。2.5%NaCl0反复冲洗,超声荡洗(图7)。试主尖并拍摄根尖片,显示牙胶尖到达根尖部(图8)。配合AHplus糊剂,热牙胶充填4个根管,副根管采用MTA充填。x线片可见4个根管恰充(图9)。玻璃离子暂封,降低咬合,嘱观察1月后行冠修复。1个月后患者复诊,检查见患牙暂封存,叩痛(一),不松,牙龈未见明显红肿。x线片(图10)提示较刚治疗后远中根尖暗影有缩小,但仍未完全消除。建议继续观察,1个月后复诊。

J Endod:CBCT对下颌磨牙解剖形态的观察分析

这篇研究的目的是通过锥束CT(CBCT)评估下颌磨牙的解剖形态以便根尖外科手术的顺利实施。

J Endod:牙髓病医师及住院医师通过锥束CT影像判断的准确性

有限域锥束CT影像(CBCT)已经成为牙髓科医师评估其患者牙齿及其周围组织的常用模式。准确的影像判读不仅对获取所需治疗的信息十分重要,而且也有助于辨别同时发生的结果。这篇研究的目的是为了检测牙髓病医师及住院医师通过CBCT量判读的准确性。

J Endod:CBCT鉴定根尖周炎在观察者间以及个案处理间的可靠度评估

准确的X线片解读对患者的诊断和治疗具有极其重要的意义。之前的研究表明,不论使用常规的X线摄像、数字X线摄像或锥束CT(CBCT)影像,都存在对根尖组织X线解读的主观性。另外,还没有研究通过尖周X线可透射性(PAR)的范围来评估对尖周组织解读的可靠性。这篇研究的目的是通过不同领域和具有不同程度经验的读片者在鉴定不同大小PARs时评估CBCT影像解读在观察者间和个案处理间的可靠度。

J Endod:没有明显口内X线阴影的牙齿在CBCT影像下尖周透射区的发生率及大小
