[Dentine hypersensitivity treated with Nd: YAG laser: experience with 262 cases].

OBJECTIVE

To observe the curative effect of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser pulse in treating dentine hypersensitivity.

METHOD

A total of 262 teeth with dentine hypersensitivity were divided equally into 2 groups, namely the test group which received treatment with pulse Nd: YAG laser and the control group treated with sodium fluoride.

RESULTS

The instant, 1-month and 6-month effectiveness in the test group was better than that in the control group, showing significant difference between the two groups (P<0.01).

CONCLUSION

Nd: YAG laser is safe and highly effective in treating dentine hypersensitivity.
