| Summary: | <p>The aim of this laboratory based study is to assess the efficiency of a tooth bleaching agent by measuring the degree of color change with a spectrophotometer (Konica Minolta, CM 2600d) and not by the usual subjective visual guide methods. Objectives of the study are: To determine tooth shade with a spectrophotometer prior to staining the tooth (baseline). To determine which insult causes the most discoloration numerically. To measure the efficiency of the bleaching agent used in the study with periodic color change pectrophotometer readings.  === To assess if the baseline tooth shade can be regained by the bleaching agent.</p> |
