Laser technology is currently receiving considerable attention in prosthodontics and this interest covers both clinical and technical aspects of prosthodontics. Given the increasing use of lasers in Europe, these authors set out to evaluate the effects of one laser type (Nd Yag) on three non-precious alloys. The methods section is slightly vague, with little explanation of the series of wires chosen and no explanation why alternative welding techniques were not used as a treatment control. Interesting results showing differences between the alloys flag up the potential for clinically significant findings. Unfortunately, no statistical analysis appears to have been carried out on the results to substantiate the findings of the investigation. The discussion makes valid points about the need to be familiar with the composition of the alloys and they make a valid point about the need to manipulate the components of the weld joint more critically.
