ABSTRACT
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.
