Odontogenic pain from various dental issues significantly impacts quality of life, necessitating effective treatment during emergency dental care. Endodontic access cavity preparation is essential for alleviating symptoms and preventing further infection. This procedure aims to achieve symptom relief while conserving as much tooth structure as possible. This paper discusses the importance of proper endodontic access, emphasising the balance between adequate disinfection and preserving tooth integrity. It also identifies challenges in endodontic access cavity preparation. This study reviews existing literature on endodontic access, examining different approaches to access cavity preparation and the tools and techniques used. Factors affecting access difficulty, including tooth anatomy, patient-related challenges and operator skills, are evaluated, alongside advancements in imaging and instrumentation. The review shows conservative techniques, like minimally invasive access cavities, which helps to preserve tooth structure but requires advanced skills and may risk incomplete disinfection. Cone beam computed tomography (CBCT) aids in complex cases, improving canal location accuracy. Operator skills and proper equipment are key to success. Traditional cavities offer better access but can weaken the tooth, while conservative approaches maintain structure but demand more expertise. Imaging tools, including CBCT, are beneficial for complex anatomy but can be costly. To conclude, effective endodontic access cavity preparation requires a balanced approach tailored to each case. While conservative methods offer advantages in preserving tooth structure, their success depends on operator expertise and equipment. Incorporating imaging advancements like CBCT can enhance access success, especially in anatomically complex cases, but careful assessment of case complexity remains crucial.
各种牙齿问题引起的牙源性疼痛会严重影响生活质量,因此在紧急牙科治疗期间需要进行有效的治疗。根管治疗开髓预备对于缓解症状和防止进一步感染至关重要。该操作旨在缓解症状的同时尽可能保留更多的牙齿结构。本文讨论了正确的根管治疗开髓的重要性,强调了充分消毒与保持牙齿完整性之间的平衡。它还指出了根管治疗开髓预备中的挑战。本研究回顾了关于根管治疗开髓的现有文献,研究了开髓预备的不同方法以及所使用的工具和技术。评估了影响开髓难度的因素,包括牙齿解剖结构、与患者相关的挑战和操作者技能,以及成像和器械方面的进展。综述表明,保守技术,如微创开髓腔,有助于保留牙齿结构,但需要先进的技能,并且可能存在消毒不彻底的风险。锥形束计算机断层扫描(CBCT)有助于处理复杂病例,提高根管定位的准确性。操作者技能和合适的设备是成功的关键。传统的开髓腔提供更好的操作通道,但会削弱牙齿,而保守方法能保持牙齿结构,但需要更多专业知识。包括CBCT在内的成像工具对于复杂的解剖结构有益,但成本可能较高。总之,有效的根管治疗开髓预备需要针对每个病例采取平衡的方法。虽然保守方法在保留牙齿结构方面具有优势,但其成功取决于操作者的专业知识和设备。采用如CBCT等成像技术的进展可以提高开髓的成功率,特别是在解剖结构复杂的病例中,但仔细评估病例的复杂性仍然至关重要。
