Abstract:
OBJECTIVETo investigate the effect of the restoration for pathological tooth wear.
METHODSA total of 48 pathological weared premolars and molars with restorable space in occlusal surface in 10 patients were restored by composite resins. The patients' masticatory function (biting force, masticatory efficiency, the surface electromyographic (EMG) activity of masseter muscles and anterior temporalis) were compared before and after the treatment. At the same time, the restorations were evaluated according to the modified the United States Public Health Service (USPHS) criterion.
RESULTSAfter the treatment, patients' clinical syndrome disappeared, the biting force was improved (P < 0.05) and the masticatory efficiency was increased significantly (P < 0.01). EMG activity, the asymmetry index and the action index of the tested muscles during different status had no significant change (P > 0.05). The composite resin restorations of the 48 teeth were all evaluated as A after three month and one year.
CONCLUSIONSRestoring the pathological weared posterior teeth with composite resins is an effective treatment to relieve the patients' syndrome, improve their masticatory efficiency and biting force.
