Did a surgical extraction of a lower molar using the chisel tip with my DELight. After we got done, my assistant said “What the heck was that?”. Ablates tooth and osseous like a hot knife in butter.

Have been doing some work etching occlusals of molars with 35% phosphoric acid prior to erbium ablation. It does seem to initially increase the speed of ablation. But once you get through the shallow layer that is etched, seems to slow down. Almost like you would need to stop and re-etch.

This morning I was so glad I had my erbium. Developmentally challenged child came out of hygiene with occlusal caries on #31. Child was very nervous, fidgety and had limited opening. I was able to sneak my 80 degree tip in and prepare the tooth without chemical anesthesia.
