The effect of new Tubulicid on smear layer removal.

The effects o f new Tubulicid R (a commerical cavity cleanser which contains 0,2 per cent disodium EOT A) on smear layer removal from ground and cavity dentine surfaces with and without mechanical agitation were de­ termined. None o f the surfaces displayed smear layer re­ moved scores greater than one. Although mechanical agi­ tation appeared to improve the smear layer removed properties o f new Tubulicid R this was found not to be significant. The difference between smear layer removal from ground surfaces and cavity surfaces was also found not to be significant. A significant difference in smear layer removal (p<0,02) was however, found when flat ground dentine treated with new Tubulicid R and mech­ anical agitated surfaces were compared to cavity surfaces subjected to chemical cleansing alone.
