The aim of the study was to compare the fluorescence difference of teeth which were bonded using TransbondTM Plus self etching primer (SEP) and 37% orthophosphoric acid, with the aid of quantified light-induced fluorescence (QLF) method. QLF technology is a unique intra-oral technique that can be used for the detection of white spots, fluorosis, plaque/calculus/bacterially infected caries. Thirty eight patients (666 teeth) who have been under fixed orthodontic treatment for an average period of 1.8 years were selected. According to the bonding procedure which was used during bracket placement, they were divided into two groups. First group consisted of 18 patients (330 teeth), bonded with SEP; second group was comprised of 20 patients (336 teeth), whose bonding was done by using 37% orthophosphoric acid. Buccal views of the teeth were captured and QLF analysis was carried out. In 37% orthophosphoric acid group upper teeth compared to the lower teeth and upper anterior compared to the upper posterior teeth were found to be more prompt to the plaque accumulation and demineralization. Within the limitations of the study SEP was found to be more enamel friendly than 37% orthophosphoric acid.  (Rev Esp Ortod. 2011;41(2):065-070)
