Development of dental material glass ionomer cement removal technique using ND:YAG laser / Noorsyazwani Zulkifli
Laser glass ionomer cement (GIC) removal is identified as an ideal technology to replace conventional technique in GIC removal process. The traditional method in GIC removal will lead to soft tissue inflammation, gingival bleeding, and crestal bone loss. A unique characteristics of laser technique s...
