This article reports the endodontic and surgical management and 12-month follow-up of a maxillary lateral incisor diagnosed as type III dens invaginatus. A 21-year-old male patient presented to our clinics with complaints of pain and swelling in the right maxillary region. Intraoral and radiographical examination disclosed the presence of a peg-shaped maxillary right lateral incisor diagnosed as type III dens invaginatus. Root canal treatment combined with periapical surgery was initiated. After the completion of root canal treatment for both maxillary right central and lateral incisors, periapical surgery was scheduled. During the surgery, periapical granulation tissue was curreted and bovine-derived hydroxil apatite (Unilab-Surgibone, Mississauga, Ontario, Canada) covered with collagen membrane (Unilab-Surgibone) was placed in the resorptive areas. ProRoot MTA (Dentsply, Tulsa, OK) was placed as a root end filling material. Postoperative 12-month follow-up revaled a satisfactory healing process.
本文报道了一例被诊断为III型牙内陷的上颌侧切牙的根管治疗、外科治疗及12个月的随访情况。一名21岁男性患者因右上颌区域疼痛和肿胀前来我院就诊。口腔内及影像学检查发现右上颌侧切牙呈钉状，诊断为III型牙内陷。遂开始进行根管治疗并联合根尖手术。在上颌右中切牙和侧切牙完成根管治疗后，安排了根尖手术。手术过程中，刮除根尖肉芽组织，并将覆盖有胶原膜（Unilab-Surgibone）的牛源羟基磷灰石（Unilab-Surgibone，加拿大安大略省密西沙加市）置于吸收区域。使用ProRoot MTA（登士柏，美国俄克拉何马州塔尔萨市）作为根尖充填材料。术后12个月的随访显示愈合过程令人满意。
