These standards help ensure proper root positioning, since they are not based solely on the clinical crowns. Objective: to use the USC root vector analysis to measure the tip and torque of teeth to establish Caucasian norms. Methods: We measured and obtained mean mesiodistal and faciolingual angulations from each whole tooth from 34 pretreatment and 43 previously treated Caucasian patients, by using the University of Southern California root vector analysis program in Dolphin 3D. We used descriptive statistics to present normal torque and tip values. Two-Sample t-test was executed to compare right tip and torque values to the left side. One sample t-test was used to compare our Caucasian sample to the multi-ethnic sample in Tong et al. paper, and to compare pretreatment to post-treatment patients within the Caucasian group. Results: Comparing right to the left tip and torque values in our sample showed no significant difference (P[greater than]0.05). We compared our study sample to the USC sample norm and we found that there was statistical significant difference in almost all tip and torque values (P[less than]0.05). We found no statistically significant difference in angulation of teeth between treated and untreated Caucasian patients. Conclusion: We measured and obtained mean mesiodistal and faciolingual angulations from each whole tooth from 34 pretreatment and 43 previously treated Caucasian patients′ by using the University of Southem California root vector analysis program in Dolphin 3D. When comparing the right side to the left side of the treated and untreated Caucasian groups, there was no statistically significant difference between the measurements for either tip or torque. We found a statistically significant difference in angulation of teeth between Caucasian and USC populations. We found no statistically significant difference in angulation of teeth between treated and untreated Caucasian patients.

Indiana University-Purdue University Indianapolis (IUPUI) / This study was conducted in order to determine if there is any change in the active ingredient of tooth-whitening agents when the products are received from the manufacturer (Baseline), two months, four months, and six months after they are received, under two different storage conditions. Thirty-six products were received from multiple manufacturers: eight with hydrogen peroxide and 28 carbamide with peroxide products. All the bleaching syringes for a specific product were from the same lot. Once the products were received, one sample of each product was stored at room temperature and the other sample was stored in a refrigerator. Assays to determine the baseline concentration were performed within the first two weeks of their arrival and again 2 months, 4 months, and 6 months after receiving the products. All samples were analyzed for peroxide content by using the United States Pharmacopeia recommended method. The results obtained from this study show the following: 1. Bleaching products have different concentrations than what are indicated on the label. 2. Storage of bleaching products for an extended time at room temperature can cause bleaching products to lose some of their potency. 3. The preferable storage condition verified in this study is under refrigeration.
