Analyzing marginal integrity, marginal discoloration, postoperative sensitivity, caries and anatomic form we had 100% of success (Alfa or Bravo scores) at one year, in agreement with other same clinical trials,[ 8 14 ] but in relation of anatomic form, although the results were clinically acceptable, we had an almost significant ( P = 0.058) values bravo to the experimental group, which allows us to suppose that in longer periods of evaluation, this difference may represent significant results.
