The aim of this study was to compare the survival of composite resin restorations retained by glass fiber posts or reversed-orientated (upside-down) metal posts in severely decayed primary anterior teeth after 6, 12, and 18 months.
A total of forty-four 3- to 5-year-old children with bilateral severely decayed primary maxillary canines were included. Patients were treated under general anesthesia. After pulpectomy, an intracanal post was seated in the primary maxillary canine on each side: either a glass fiber post or a metallic post in reversed orientation and teeth restored with light-cured composite. Survival rate of each technique was evaluated at predetermined follow-ups and data were analyzed with McNemar's test (α = 0.05).
The difference in survival of restorations retained by two types of posts was not statistically significant in clinical and radiographical evaluations after 6, 12, and 18 months. The survival rate of reversed-orientated metal and glass fiber posts after 18 months was 81.1 and 67.6% respectively (p = 0.14).
Reversed-orientated metal post did not show lower clinical survival compared with glass fiber posts in 18-month follow-up. Hence, reversed-orientated metal post can be considered as a potential method to obtain retention for composite restorations in severely decayed primary anterior teeth.

本研究旨在比较玻璃纤维桩或倒置（颠倒）金属桩固位的复合树脂修复体在严重龋坏的乳前牙中6个月、12个月和18个月后的存留情况。
纳入44名3至5岁双侧上颌乳尖牙严重龋坏的儿童。患者在全身麻醉下接受治疗。根管治疗后，在每侧上颌乳尖牙中植入根管桩：要么是玻璃纤维桩，要么是倒置的金属桩，并用光固化复合树脂修复牙齿。在预定的随访中评估每种技术的存留率，并采用McNemar检验（α = 0.05）分析数据。
在6个月、12个月和18个月后的临床和影像学评估中，两种桩固位的修复体存留率差异无统计学意义。18个月后，倒置金属桩和玻璃纤维桩的存留率分别为81.1%和67.6%（p = 0.14）。
在18个月的随访中，倒置金属桩的临床存留率并不低于玻璃纤维桩。因此，倒置金属桩可被视为严重龋坏乳前牙复合树脂修复体获得固位的一种潜在方法。如何引用本文：Vafaei A, Ranjkesh B, L0vschall H, Erfanparast L, Jafarabadi MA, Oskouei SG, Isidor F. 玻璃纤维桩或倒置金属桩固位的严重龋坏乳前牙复合树脂修复体的存留情况。《国际临床儿科牙科学杂志》2016；9(2):109 - 113。
