Low-level laser therapy (LLLT) is increasingly being used in the regeneration of soft tissue. In the regeneration of hard tissue, it has already been shown that the biomodulation effect of lasers repairs bones more quickly. We studied the activity in bone cells after LLLT close to the site of the bone injury. The femurs of 48 rats were perforated (24 in the irradiated group and 24 in the control group)...
This ablation rate study has been carried out with a fibre-deliverable, 308 nm, XeCl laser, producing long pulses of 200 ns as opposed to the usual 10–20 ns. This in-depth study aimed to evaluate the ablation rates for this longer pulse length. The effects on the ablation depth of dentine, enamel, soft tissue and bone were investigated ex vivo. Radiant exposure, number of pulses, pulse repetition...
