Effects of marginal adaptation with different materials on restoring dental wedge-shaped defects

Abstract

Objective To evaluate the effects of marginal adaptation with different materials on restoring dental wedge-shaped defects. Methods From January 2016 to July 2016, 80 patients with 172 wedge-shaped defect teeth in Stomatological Hospital of Haishu District were chosen and randomly divided into three groups according to random number table method, 26 patients with 55 defect teeth were treated with Fuji glass ionomer(group A), 23 patients with 59 defect teeth were treated with Carey charismatic light-cured composite resin(group B), and the other 31 patients with 58 defect teeth were treated with beautifil flow plus reinforced polymer F03(group C). Marginal adaptation of three groups of different materials of the teeth were measured. Results The micro-leakage depth among the three groups had statistically significant difference(H=7.036, P=0.035). The micro-leakage depth of group A, B and C were (1.10±0.05)mm, (0.96±0.05)mm, (0.78±0.06)mm, respectively.There was statistically significant difference among the three groups(F=22.371, P=0.005). Conclusion The marginal adaptation of beautifil flow plus reinforced polymer F03 is superior to FujiⅡglass-ionome and Charisma composite resin, and has benefits for treatment of wedge-shaped defects.
