What did Stern and Sognnaes report in 1965 regarding ruby lasers?

In 1965, Stern and Sognnaes conducted research that demonstrated the ability of ruby lasers to vaporize dental enamel. This finding was significant at the time because it highlighted the potential medical and dental applications of laser technology, particularly in procedures involving hard tissues like tooth enamel. The capability to selectively remove or alter hard tissues without affecting neighboring areas was a valuable advancement in dental treatment.

Their research contributed to the understanding of how lasers could be employed in precise and minimally invasive ways, marking an important step forward in laser dentistry. By establishing that ruby lasers could effectively target enamel, they opened the door for further exploration into other applications of lasers in dentistry and medicine, validating the utility of laser systems in clinical scenarios.
