ABSTRACT
Objective To investigate the combined effects of diode laser and Green or for dentin hypersensitivity in the elderly.Methods Thirty-six elderly patients (108 exposed sensitive teeth) were randomly allocated into three equal groups.Group A (desensitization therapy with diode laser and Green Or),Group B (desensitization therapy with diode laser only) and Group C (desensitization therapy with Green Or only);the curative effects in the 3 groups were observed instantly,3 months after treatment respectively.Results The results show no obvious difference of the instant curative effect among the 3 groups;The effective rates of the 3 groups kept descending with the time going,3 months after therapy,the rate of Group A was significant difference from that of Group B and Group C;the rate of Group B was no significant difference from that of Group C.Conclusion It was concluded that the diode laser combined with Green Or was a effective treatment option.
