Palatal radicular groove leads to severe endo-periodontal lesion in lateral incisors. The groove occurs on the labial and lingual root surfaces, while the localized periodontal pocket develops along the lingual groove length. The complicated root canal system, extensively destroyed bone lamella, and persistent fistula pose a challenge for root canal therapy, tooth retention, and thorough infection control inside and outside of the root canal. Combining microscopic root canal therapy with intentional replantation and nano-biomaterial application facilitates infection control, tooth retention, and formation of newly periodontal attachment.
腭侧根面沟可导致侧切牙出现严重的牙髓-牙周联合病变。该沟出现在唇侧和舌侧牙根表面，而局限性牙周袋沿舌侧沟的长度发展。复杂的根管系统、广泛破坏的骨板和持续性瘘管给根管治疗、牙齿保留以及根管内外的彻底感染控制带来了挑战。将显微根管治疗与意向性再植和纳米生物材料应用相结合，有助于控制感染、保留牙齿并形成新的牙周附着。
