CONCLUSION: Traumatic occlusal force, periodontal lesions, teeth with root canal therapy are the major causes that led to vertical root fractures.
結論:咬颌創傷,牙周疾病,牙髓無活力等是導緻牙根縱裂的重要原因。
Method Using two different root canal filling materials for deciduous teeth.
方法用兩種根管充填材料對乳前牙進行根管治療。
Objective To discuss the clinical effects and feasibility of repairing old root canal perforation of front teeth using DMG calcium hydroxide.
目的探讨DMG光固化氫氧化鈣修補前牙陳舊性根管穿孔的臨床效果及可行性。
Methods 38 teeth of old root canal perforation on the lip were repaired with DMG light-curing calcium hydroxide remedial, and were recalled periodically, observed the effect of treatment.
方法對38顆前牙陳舊性根管穿孔經唇側根面采用D MG光固化氫氧化鈣進行修補,定期回訪,觀察治療效果。
Objective to analyze the effect of preserving severely damaged teeth such as stubbed tooth root, crown and vertically fractured tooth through compositive therapy.
目的利用綜合治療,對殘根、殘冠、縱折牙等嚴重缺損牙進行保存治療并分析其療效。
Teeth after root canal therapy must go through a period of observation, after determining no symptoms, to subsequent dental treatment.
根管治療後的牙齒必須經過一段時間的觀察,确定無症狀後,才能進行後續的牙齒重建治療。
METHODS: 25 extracted human maxillary anterior teeth, with a single straight root were randomly divided into 5 groups. They were instrumented with K-files and conventional preparation technique.
方法:25顆離體直根管前牙,隨機分為5組,不鏽鋼K锉常規法預備根管,應用5種沖洗劑組合進行沖洗。
|fang;牙根
牙齒根部(teeth root)是牙齒結構中位于牙龈下方的部分,負責固定牙齒并傳遞營養。以下為詳細解析:
解剖結構
牙根由牙骨質覆蓋,内部包含牙髓腔延伸的根管系統,内含血管和神經組織。根據美國牙科協會(ADA)資料,牙根長度通常占牙齒總長的1/3至2/3,不同齒位的牙根數量不同,例如前牙多為單根,臼齒常含2-3個根[來源:美國牙科協會官網]。
生理功能
牙根通過牙周膜纖維與牙槽骨連接,形成牙齒的懸挂系統,可緩沖咀嚼壓力。研究顯示,牙根表面的牙骨質具有再生能力,有助于牙齒在正畸過程中的移動[來源:《牙科研究雜志》]。
常見病變
根尖周炎是牙根尖部組織的炎症性疾病,多由齲齒或外傷引起。世界衛生組織(WHO)統計顯示,根管治療作為保留病變牙根的主要方法,全球年實施量超過1500萬例[來源:WHO口腔健康報告]。
臨床意義
牙根吸收是正畸治療中的潛在并發症,現代錐形束CT技術可将診斷準确率提升至93%以上。種植牙技術中,钛合金牙根替代體的骨結合率可達98%-100%[來源:國際口腔種植學會白皮書]。
“teeth root”是英語中關于牙齒結構的術語,以下是詳細解釋:
