“…A similar study carried out on Indian population reported that with increasing age, there was a tendency for the teeth to be of darker shades [20]. This is largely due to factors like secondary dentin formation after the age of 35 and enamel thinning because of tooth wear [23]. Therefore, the present study was conducted only on students of the university age 19-32 to exclude the age factor and results are obtained from natural teeth which are not affected by any physiological changes, like formation of secondary dentin, which gives the tooth appearance of low value color.…”

Introduction. Color of teeth is undoubtedly one of the most important factors considering patients' satisfaction with the quality of their restoration, especially in the anterior region of the mouth. Therefore, the determination of color is an integral part of esthetic dentistry and therefore it should be given the highest importance in dentistry in order to achieve the esthetic requirements of patients.Aim. The aim of this study was to evaluate tooth color in 3 different ethnic groups and its relationship with gender and type of tooth using a clinical spectrophotometer.Material and methods. A total of 90 dental students of the Medical University of Lublin was divided into three groups of 30 each according to participant's ethnicity, which was as follows: Polish, Saudi Arabian and Taiwanese. Then, different divisions were made according to gender as well as the type of teeth. The tooth color was identified by spectrophotometer. The data was statistically analyzed.Results. For the Vita Classical shade guide, A3.5 shade was the most frequently chosen in Taiwanese and Saudi students' teeth. However, the most common shade observed for the anterior teeth of Polish students was A3. The most common shade among males was A3.5 and in females A3 was the most frequent shade. In all 360 central incisors, overall, the most common shades noticed were A2, D3 and C1. In all 360 lateral incisors, D3, A3 and A2 were the most frequent shades for this group of teeth. In all 360 canines, A3.5 and A3 were the most common shade with almost half of the number of canines in this study was measured with A3.5.Conclusions. Based on the performed preliminary research, it was observed that Polish students tend to have brighter teeth than Saudis which in turn have even brighter teeth than Taiwanese students. It was also noted that men are more likely to have darker shade values than women. Central incisors have higher values of tooth color than lateral incisors and canines.

“…The canines have greater chroma saturation and also are lower in value than any of the other anterior teeth. First and second premolars appear lighter and brighter than the canines and have a value similar to that of the lateral incisors [24].…”

The advantage of electronic devices is to eliminate the subjectivity. Based on individual capabilities, visual perception has its disadvantages. The aim of this study was to find out the possible shade difference between the upper and lower teeth, visual perception versus spectrophotometry as well as proving that females are better in visual perception of colour matching. 82 subjects (dental students) of this study determined the color of each other's natural teeth. The color of 1640 teeth (incisors, canines and premolars), was matched by visual perception and by Vita Easyshade spectrophotometer. The matching was focused on the middle third of buccal surfaces of the examined teeth. In this study, it was found that there was a difference of color between the teeth of the upper and lower jaw. The percentage of the accordance between two methods was 28.35% for all examined teeth. The color determination at central incisors showed the highest value of accordance 40.85%. Based on Vitapan 3D Mastershade, the most frequent color was 2M2.

“…In the present study, maxillary central incisors and canines were selected because maxillary teeth are more visually prominent and "yellowish" than mandibular teeth (25). In addition, the color difference between central incisors and canines is generally larger than that between central and lateral incisors (26).…”

Comparison of efficacy and outcome satisfaction between in-office and home teeth bleaching in Chinese patients

This in vivo study aimed to evaluate the efficacy of in-office and home teeth bleaching in Asian patients. Moreover, the correlation between tooth color change and patient's outcome satisfaction was investigated. Overall, 40 Chinese patients were randomly divided into two groups and prescribed in-office (OB) or take-home bleaching (HB). The color of the maxillary central incisor and canine were recorded at baseline, immediately after first treatment, 1 week, and 3 months after treatment by using a spectrophotometer. Bleaching sensitivity and outcome satisfaction were assessed using Likert and visual analogue scale (VAS), and the results were analyzed using independent t-test and Pearson correlation (P < 0.05). ΔL*, Δa*, Δb*, and ΔE* values of HB were greater than those of OB. Color changes observed in canines were generally greater than those in incisors. Moreover, HB was generally associated with less tooth sensitivity than OB. Patients were satisfied with both treatments, but VAS scores were greater for HB. Furthermore, the correlation between ΔE* and VAS was significant for canines immediately after the first treatment and 1 week after HB. In conclusion, HB was more effective in lightening teeth and reducing chromacity in Chinese patients. The correlation between tooth color change and outcome satisfaction was generally insignificant and weak.
