Atkinson et al. (1984) found that their air-powder abrasive system removed a mean depth of 637µm of root structure in 30s of exposure time. Further research aimed at identifying less abrasive powders is ongoing (Petersilka et al. 2003), because softer particles might be more effective in removing carious dentin more selectively. Lau-
  16. 16. Administration approved the erbium:YAG laser for caries removal in the USA. The Fidelis erbium:YAG laser (Fotona, Ljubljana, Slovenia) is one example of the commercially available lasers for dental use, but it is a rather large device (Fig. 2.1), with settings for varying the cutting speed (Fig. 2.2). Erbium:YAG laser treatment of teeth produces no smear layer, so the adap- tation of filling materials to the enamel and dentin surfaces should be optimal. Fig. 2.1 The erbium-YAG laser is commer- cially available, but many perceive it as costly and offering few advantages over conventional methods of cavity prepara- tion. The machine is large and occupies considerable space in the dental office
  17. 17. Carisolv® gel multimix 25% faster compared with previous gel The removal of caries with the new gel takes an average of 5.2 min- utes, less than 30 per cent of the total treatment time. This develop- ment of Carisolv® makes it possible to remove caries as fast as with the drill but with all the advantages a minimally-invasive method Minimally-invasive, precise and reliable caries removal
  18. 18. Carisolv® – minimally-invasive method for caries removal Minimally-invasive dentistry comprises biologically- oriented procedures. The teeth are treated with preci- sion and caution in order to last as long as possible, avoid post-operative complications and fulfil the de- mands of present-day patients. Using the gel-based caries removal method Carisolv® brings you as close to minimally-invasive procedures as possible. The method involves the use of a gel that selectively reacts with denatured collagen, thereby mak- ing the carious dentine softer. Specially-designed instruments – hand and power-operated – are used to remove the softened material. Drill, air abrasion or similar techniques are used if access to the cavity is required. Carisolv® • Well documented • Minimally-invasive, selective and precise • Minimises the need for the drill and anaesthetics and enhances patient comfort • Makes it possible to avoid drilling close to the pulp • Carisolv® instruments with sharp yet blunt cutting angles help to protect healthy tissue Carisolv® – the clinical procedure 1. The gel does not affect healthy dentine or soft

The gel does not affect healthy dentine or soft tissue. Nor does it affect enamel. Consequently Carisolv™ should be used in combination with the drill or alternative techniques. 2. Drilling could preferably be used whenever the cavity needs to be opened up, for adjustment of cavity periphery or whenever there are large amounts of caries and when the risk to affect healthy tissue is minimal. 3. Cover the cavity with gel and wait for 30 seconds until the carious dentine has been softened. 4. Softened caries can then be scraped away using the PowerDrive™ and/or the Carisolv® hand instruments. 5. Repeat steps three and four without waiting 30 seconds, until the cavity is free from caries. 6. Inspect and fill as usual. syringe should be sufficient for approximately 10 treat- ments. Only the amount of gel that is needed for each individual treatment is extruded. An opened package can be kept at room temperature during working hours. At all other times, it should be kept in a refrigerator. An opened package can be kept up to one month, for subsequent use. The gel comprises uncoloured fluid of high viscosity, which contains three different amino acids, and a trans- parent fluid consisting of a low concentration of so- dium hypochlorite. When the fluids are mixed, their
