Two Kinds of Repair Methods for Teeth Depth of the Wedge-shaped Defect

To compare the observed light-cured calcium hydroxide bottom composite Dyract after repair and the direct use of Fuji II glass ionomer cement neck deep wedge-shaped defects in dental clinical efficacy.178 cases of tooth neck deep wedge-shaped defect in patients with 412 teeth were randomly divided into two groups.Group 1 Fuji II glass ionomer direct repair.Group 2 using light-cured calcium hydroxide bottom composite Dyract after repair.6-24 months follow-up after,the results were significantly different after two years(P0.05),six months no significant difference(P0.05).2 years after the first set of edge adaptation,secondary caries and periodontal dental pulp are superior to group 2(P0.05).Repair of glass ionomer cement direct treatment of wedge-shaped defects over the depth of light curing calcium hydroxide to bottom with Dyract complex repair,FujiII direct filling of glass ionomer cement is an ideal depth of wedge-shaped defect repair technology.
