Root canal obturation is a critical phase in endodontic therapy, aimed at preventing reinfection and ensuring long-term therapeutic success. The quality of obturation is determined by the ability of the filling material to effectively seal the root canal system, preventing microbial invasion and minimizing the risk of recurrent infection. Various obturation techniques, including Cold Lateral Condensation, Carrier-Based, Thermoplasticized Injectable, and Cold Free-Flow Compaction, are employed, each with distinct advantages and disadvantages in terms of material adaptation, ease of application, and the potential for void formation.
This study utilized Cone Beam Computed Tomography (CBCT) for a comprehensive volumetric examination of the four root canal obturation techniques. CBCT was used to assess the material's ability to fill the root canal space and identify the presence of voids, which could compromise the effectiveness of the obturation.
The Cold Lateral Condensation technique, while being cost-effective and easy to apply, may result in voids due to gaps between the gutta-percha cones. Other techniques, such as Carrier-Based and Thermoplasticized Injectable, offer improved adaptation and reduce the risk of void formation but may come with increased cost or complexity in application.
The study underscores the importance of choosing an obturation technique that balances cost, ease of application, and material adaptation to ensure effective root canal sealing and minimize the risk of reinfection.
根管充填是牙髓治疗中的关键阶段,旨在防止再次感染并确保长期治疗成功。充填质量取决于充填材料有效封闭根管系统的能力,防止微生物侵入并将反复感染的风险降至最低。采用了各种充填技术,包括冷侧方加压充填、载体类、热塑注射充填和冷自由流动压实充填,每种技术在材料适应性、操作简便性和形成空隙的可能性方面都有各自的优缺点。
本研究利用锥形束计算机断层扫描(CBCT)对四种根管充填技术进行全面的容积检查。CBCT用于评估材料填充根管空间的能力并识别空隙的存在,空隙可能会损害充填的有效性。
冷侧方加压充填技术虽然经济有效且易于应用,但由于牙胶尖之间的间隙可能会导致空隙。其他技术,如载体类和热塑注射充填,具有更好的适应性并降低了形成空隙的风险,但可能会增加成本或操作复杂性。
该研究强调了选择一种在成本、操作简便性和材料适应性之间取得平衡的充填技术的重要性,以确保有效的根管封闭并将再次感染的风险降至最低。
