Abstract
Clinical lasers are of two types; soft lasers are essentially an aid to healing with relatively few rigorous studies available to support their use. Surgical hard lasers, however, can cut both hard and soft tissues and replace the scalpel and drill in many areas. From initial experiments with the ruby laser most clinicians are using Argon, CO2 and now NdYAG systems. The first dental laser based on a NdYAG engine provides handpieces of similar size to conventional instrumentation and, being fed by a fibre-optic 'cable', has the flexibility for intra-oral use that the CO2 lasers, widely used in oral surgery, lack. Furthermore, extensive clinical investigation has demonstrated their safety in clinical practice and the fact that procedures can usually be performed without a local anaesthetic is obviously seen as a considerable advantage by patients. Sterilising as it cuts, the NdYAG laser promises to find uses not only in caries removal and soft tissue surgery, but also in endodontics and gingival curettage
