Thirty-six teeth were stained, bleached and restored using four restorative techniques. The final tooth shade was determined subjectively by visual observance, and objectively by actual measurement of light transference. The teeth with silicate in the canal and chamber, when compared to those with white cement or composite in the canal and chamber, were subjectively evaluated as lighter at a significance level of p .02. Evaluation, utilizing light transference, showed that when only silicate was placed in the canal, chamber and access preparation, there was greater translucency at a significance level of p .0002. Evaluation of both objective and subjective data indicated that the preferable technique for restoring bleached teeth would be silicate in the canal and chamber area covered by a composite in the access preparation.
