Rubber dam vs Isolite system

• Rubber dam isolation for restorative treatment in dental patients 2021 · Cochrane All outcomes

  Pit and fissure sealing (permanent molars)
  Rubber dam may be associated with significantly lower satisfaction than the Isolite system but evidence very uncertain, mainly worse comfort (31%, P=0.02) and less preference (26%, P=0.002) (Alhareky 2014).

• Rubber dam isolation for restorative treatment in dental patients 2021 · Cochrane All outcomes

  Non-carious cervical lesions (composite restoration)
  Evidence did not support higher acceptance/preference for rubber dam than cotton rolls (P = 0.85 from binomial test on 28 participants; very low-certainty evidence) (Loguercio 2015).
