The document discusses the use of soft-tissue diode lasers for aesthetic crown lengthening. It notes that diode lasers offer unprecedented precision and hemostasis compared to traditional scalpels. The document outlines different generations of diode lasers, their wavelengths, hemostasis abilities, and cutting properties. It lists advantages like dry surgery, sterilization, reduced infection, and faster healing. Disadvantages include possible carbonization, eye injury, and lack of tactile feedback in non-contact mode. The conclusion is that diode lasers are a suitable alternative to traditional crown lengthening if used properly to minimize collateral damage.

1. A LASER SMILE
Aesthetic crown lengthening is a technically
demanding endeavour that requires higher degree
of precision than what may be achieved with a
scalpel blade.
Soft-tissue diode lasers offer unprecedented
levels of precision while achieving excellent
hemostasis and faster healing compared to
electrosurgery and traditional scalpel .

6. Conclusion
Diode Lasers are compact and reliable
surgical instruments which are suitable
alternative to conventional aesthetic
crown lengthening techniques in terms
of clinical effectiveness and practicality
and would be a welcome addition to
armamentarium of a dentist if a
suitable protocol could be applied to it
minimizing collateral damage.
