摘要:

本病例为上颌侧切牙畸形舌侧沟致牙周牙髓联合病损病例,唇腭根面的凹陷、腭侧窄而深牙周袋、根管系统的峡部、破坏严重的唇腭骨板和迁延不愈的瘘道等,给控制根管内外感染保留该牙提出了严重挑战。本病例采用显微根管治疗技术、意向性牙再植术以及纳米生物活性材料,实现了对该患牙的感染控制、患牙保留以及牙周新附着的形成。

Abstract:

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 compli-cated 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.

Key words: microscopic root canal therapy, intentional replantation, palatal radicular groove, endo-periodontal lesion
