Study Notes

Alternatives to Conventional Cavity Preparation

  • Alternative methods of cavity preparation are summarized in Table 10.6.
  • Air abrasion:
    • Less need for local anesthesia
    • Less vibration, noise, and pressure
    • Less fracture and crazing of enamel or porcelain
    • Disadvantages:
      • Dust (particles in the air)
      • Will not remove very soft caries
      • Not efficient at removing large amalgam restorations
      • Risk of tissue laceration, air dissection, and emboli
      • There is no reliable evidence that application of ozone gas to the surface of decayed teeth stops or reverses the decay process (Rickard et al., 2004)
  • Ozone:
    • Painless
    • Disadvantages:
      • Need to use burs to gain access for the gel
      • Time taken for gel application and excavation is more than twice that needed using conventional methods
      • Still require acid etching for bonding
  • Chemomechanical:
    • Less painful and less need for local anesthetic
    • More conservative of dental tissue only caries are softened for removal
    • Disadvantages:
      • Need to use burs to gain access for the gel
      • Time taken for gel application and excavation is more than twice that needed using conventional methods
      • Still require acid etching for bonding
  • Lasers (Er,YAG):
    • Smear-layer-free cavity walls
    • Selective and localized removal of tooth structure
    • Reduced need for local anesthetic
    • Higher resistance of cavity walls to secondary decay
