短纤维带联合树脂粘接技术治疗后牙食物嵌塞的临床评价

目的：：评价短纤维带联合树脂粘接技术微创修复后牙垂直型食物嵌塞病例的临床效果。方法：纳入牙垂直型食物嵌塞病例共98例(共135个嵌塞单位)，采用石英短纤维带与纳米树脂联合及单纯纳米树脂充填术(联合法)治疗73个嵌塞单位，树脂直接充填(充填法)62个嵌塞单位。修复后12、24、36个月随访，参照美国公共卫生署修正标准以及食物嵌塞的改善状况对修复效果进行评价，并对评价结果进行统计分析。结果：修复后12、24、36个月联合法治愈率分别为97.3%、97.3%和95.9%，无效率均为0；充填法治愈率分别为85.5%、82.2%和82.2%，无效率分别为4.8%、11.3%和12.9%(组间比较， P<0.05)。结论：短纤维带联合树脂粘接技术治疗活髓后牙的垂直型食物嵌塞，可以在微创的情况下获得良好的效果。

Clinical evaluation of short fiber ribbon combined with resin bonding technology for the treatment of food impaction between posterior teeth

Objective:To evaluate the clinical effects of short fiber ribbon combined with resin bonding technology for the treatment of food impaction between posterior teeth. Methods:98 cases of vertical food impaction between posterior teeth( total of 135 vertical food impaction units) were included. 73 units were treated by short quartz fiber ribbon combined with resin bonding technology( SQFRB) and 63 by resin bonding(RB). 12, 24 and 36 months after restoration, clinical effects were evaluated referring to the Modified United States Public Health Service (USPHS) Criteria, data were statistically analyzed. Results:12, 24 and 36 months after treatment the cure rate of SQFRB was 97. 3%, 97. 3% and 95. 9%, inefficacy rate was 0, 0 and 0;the cure rate of RB was 85. 5%, 82. 2% and 82. 2%, the inefficacy rate was 4. 8%, 11. 3% and 12. 9%, respectively(between groups, P<0. 05). Conclusion:Minimally inva-sive restorations using short fiber ribbon combined with resin bonding technology is effective in the treatment of vertical food impaction between posterior teeth.
