The apical barrier technique in permanent teeth with extensive destruction of the periapical tissue and a long infection time is much more difficult to succeed, which is a clinical challenge. This study aimed to evaluate the long-term effects of iRoot BP Plus as an apical material in adult teeth. Fifty incisors and premolars were chosen for this study. All teeth were performed apical barrier with the same operator. After treatment, the teeth were clinically and radiographically evaluated at 1, 2 and 6 years. At the 1-year follow-up, 35 teeth had healed, and three patients developed an apical abscess due to root fracture at the 2-year follow-up. Six years postoperatively, one tooth showed root resorption, which was considered a failure. The long clinical evaluation confirmed that iRoot BP Plus is a suitable material for the apical barrier of mature teeth with open apices and periapical lesions.
根尖屏障技术在根尖周组织广泛破坏和感染时间较长的恒牙中难度更大，这是一项临床挑战。本研究旨在评估 iRoot BP Plus 作为成人口腔牙齿根尖材料的长期效果。本研究选择了 50 颗切牙和前磨牙。所有牙齿均由同一位医生进行根尖屏障术。治疗后，在 1、2 和 6 年后对牙齿进行临床和影像学评估。在 1 年的随访中，35 颗牙齿愈合，3 名患者在 2 年的随访中因根折发生根尖脓肿。术后 6 年，1 颗牙齿出现根吸收，被认为是失败。长期的临床评估证实，iRoot BP Plus 是一种适用于有开放根尖和根尖病变的成熟牙齿根尖屏障的材料。
