Abstract:
BACKGROUND:The large watercress molded piece is longer than that of the normal molded piece, which is suitable for dental restoration of elderly patients with gingival recession and relatively long crown.
OBJECTIVE:To test and verify the effect of large watercress molded piece on the auxiliary repair of approximal caries lesions in molars of the elderly.
METHODS:Eighty-seven senile patients with molar approximal caries were randomly divided into two groups: those were repaired by large watercress molded piece as experimental group, and those repaired by traditional amalgam molded piece ascontrol group. Then we compared the comfortable satisfaction rate, the excelent and good rate of repair and the gingival index between the two groups immediately, 1, 3, 6 and 12 months after repair.
RESULTS AND CONCLUSION:The comfortable satisfaction rate of the experimental group was significantly higher than that of the control group at 1, 3, 6 and 12 months after repair (P< 0.05), and the gingival index was significantly lower than that of the control group (P< 0.05). The excelent and good rate of the experimental group was significantly higher than that of the control group at different time points after repair (P< 0.05). No loss or fracture of the restorations occurred in the two groups. These results demonstrate that the large watercress molded piece for repairing approximal caries lesions in molars of the elderly can better restore the anatomical shape and approximal points of teeth, and reduce food impaction and gingival inflammation.
