Petrov et al. used a femtosecond laser with a high repetition rate, which is probably the future of lasers for hard-tissue removal to achieve fast and more precise ablation in dentine and enamel.1 They concluded that the ultra-fast femtosecond laser used in their work holds the promise of a significant drilling ability without collateral thermomechanical effects. It achieved high processing efficiency, overcame disadvantages of other laser systems reported, and can be used to develop an instrument for cavity preparation based on fast and precise ablation. Their further aim is to exceed the speed of conventional drilling instruments and thus to reduce the treatment time, which in turn will bring comfort to the patient.
