BACKGROUND
The restoration of an endodontically treated fractured tooth has been a challenge for restorative dentists for decades. The performance of fiber posts when used in conjunction with direct composite resin restorations have been largely unreported. This study was conducted with the aim of evaluating the survival rate of endodontically treated teeth restored with adhesive bonded fiber reinforced resin posts and direct composite core with additional crown coverage.
METHODS
Sixty patients who required endodontic treatment with post core crown were selected from outpatient department of Air Force Institute of Dental Sciences, Bangalore. Sixty-four teeth were endodontically treated and restored with fiber post and direct resin composite core restoration. Patients were evaluated immediately after restoration and reevaluated at the end of first, second and third months. After 3 months of clinical evaluation, if teeth were asymptomatic they were restored with complete coverage porcelain fused to metal restorations and evaluated immediately, and again reevaluated at the end of first, third, and sixth months.
RESULTS
After 3 months of clinical evaluation, only two teeth exhibited periapical lesion with clinical symptoms and three teeth without any clinical symptoms. Five teeth exhibited slight marginal staining, three teeth showed partial loss of restoration, and two teeth exhibited complete loss of restoration with the fracture of the post. At the end of sixth month after restoration with full coverage crown, two teeth had dislodged restoration due to fracture of post and two teeth exhibited displacement of the post.
CONCLUSION
Fiber posts are the best alternative for restoration of fractured endodontically treated teeth. Fiber posts and direct composite resin core materials are strongly recommended for restoration of endodontically treated mutilated teeth among the dental establishments of Armed Forces.
背景
几十年来，对经过牙髓治疗的折断牙齿进行修复一直是修复牙医面临的一项挑战。纤维桩与直接复合树脂修复联合使用时的性能在很大程度上尚未见报道。本研究旨在评估采用粘结纤维增强树脂桩、直接复合树脂核并额外进行全冠修复的牙髓治疗牙齿的存活率。
方法
从班加罗尔空军牙科学院门诊部选取60例需要进行桩核冠牙髓治疗的患者。64颗牙齿接受了牙髓治疗，并用纤维桩和直接树脂复合核进行修复。修复后立即对患者进行评估，并在第1、2和3个月末进行重新评估。经过3个月的临床评估后，如果牙齿无症状，则用烤瓷熔附金属全冠修复，并立即进行评估，然后在第1、3和6个月末再次进行评估。
结果
经过3个月的临床评估，只有2颗牙齿出现伴有临床症状的根尖周病变，3颗牙齿无任何临床症状。5颗牙齿出现轻微边缘染色，3颗牙齿显示修复体部分脱落，2颗牙齿修复体完全脱落且桩折断。在全冠修复后第6个月末，2颗牙齿因桩折断导致修复体松动，2颗牙齿出现桩移位。
结论
纤维桩是修复牙髓治疗后折断牙齿的最佳选择。强烈建议在武装部队的牙科机构中，使用纤维桩和直接复合树脂核材料来修复牙髓治疗后的残根残冠牙齿。
