[Abstract] AIM:To observe the effects of treatment on hypersensitive dentine by
semi-conductor laser.METHODS:126 patients were divided into two groups,experimental group
and control group.In the experimentalgroup 142 teeth were dealt with semi-conductor laser
three times.138 teeth of the control group were dealt with750ml/L sodium fluoride glycerine
to rub at local zone three times.RESULTS:The immediated total effectiveness ofthe
experimental group was 95.8%,which of control group was 75.4%.The immediate and long-time
total effec-tivenesses of the experimental group were both prominently better than those of
the control group(P<0.01).CON-CLUSION:Semi-conductor laser is a safe,effective and
convenient method to treat hypersensitive dentine.
Key words]semi-conductor laser;hypersensitive dentine
