Ablation of selected dental materials using Er,Cr:YSGG laser

The effect of Er,Cr:YSGG laser for ablation of commercialized adhesive dental materials
were studied using 12 sets of tooth samples. The surface morphology and composition of the tooth
samples was observed before and after irradiation using FESEM and EDX. Time dependency of
exposure is observed in the tooth sample. Adhesive material Grēngloo produced better ablation on
long exposure compared to adhesive material Blūgloo. The ablation effect was also compared
between presence and absence of water. The enamel surface produced is highly dependent on the
technique used to ablate the adhesive material. Without water, enamel surface appeared roughed and
depth of crater was also created. In particular, both materials produce different quality of ablation and
reacted differently under different laser parameter and setting.
