“…Persons with medium dark and dark skin were more likely to have teeth in the high value category than persons with medium fair and fair skin, and vice versa. These results agreed with the findings of many researchers such as Jahangiri L et al ( 10 ), and Suneel V. K. ( 14 ) who found an inverse relation between tooth shade and skin complexion, but disagreed with other researchers such as Esan TA et al ( 11 ), and Al-Dwairi Z ( 15 ) who found no relation between tooth shade and skin complexion. This could be due to the difference in population selection, or might be due to using different shade guides.…”

BackgroundFacial and dental aesthetics are becoming of great concern for patients, especially for the younger generation. Tooth color matching and selection is considered a vital element in order to create an attractive beautiful smile. The importance of tooth color matching is to adjust tooth colors to obtain a good match with adjacent teeth and the skin. This is considered a challenge especially if adjacent teeth were lost or records of patients’ teeth color were not available.ObjectiveThe aim of this study was to determine the relationship between skin complexion and tooth value in a Jordanian population.MethodsA cross-sectional study of 520 individuals who were randomly selected and belonging to different age groups, ranging from 15–65 years, with equal sex distribution. These patients visited the dental clinics at different Jordanian military hospitals. The study was carried out over a period of one year from 2015 to 2016. The randomly selected sample was examined by one researcher. Shade of the middle third of the labial surface of central incisor was determined visually using VITA tooth guide, 3D-MASTER shade guide. Tooth shades were divided into two categories according to their value. The skin complexion was identified using Fitzpatrick skin type test, and was categorized into two categories (fair and dark). Data were statistically analyzed using Epi Info version 6.ResultsA statistically significant tooth shade value difference was discovered among subjects of different skin color (p<0.0001). Individuals with dark skin tend to have lighter teeth, while individuals with light skin tend to have darker teeth. Out of the 304 participants that were with dark complexion 274 (90%) have light teeth, and only 30 (10%) were with dark teeth. Out of the 216 participants with light complexion 172 (80%) have dark teeth and only 44 (20%) have light teeth.ConclusionWithin the limitation of this study, there was an inverse relation between skin complexion and tooth value among a Jordanian population. Thus, considering the skin complexion when choosing tooth shades is helpful in achieving a pleasing good-looking smile, yet further investigations in this field must be carried out.

Objective To investigate the distribution of natural tooth shades by age and gender in the Korean population with a spectrophotometer. Material and Methods A total of 674 human subjects were recruited and divided into three age groups; young (16‐30), middle (31‐59), and elderly (60‐89). Each group was then subdivided according to gender. Color was measured on the upper central incisor and CIELab color coordinates were obtained. CIEDE2000 color differences ( ΔE00) between genders within each age group and between age groups for both genders were calculated. Two‐way analysis of variance (ANOVA) was used to identify the influence of age and gender on each color variable. Results The most frequent color in the Korean population was 2L1.5. L* values decreased, while b* values increased with age (P < .05). There was a significant interaction between gender and age on b* values; F (2668) = 3.489, P = .031, partial η2 = 0.010, and observed power = 0.652. Females generally have lighter and less chromatic central incisors compared to males. The ΔE00 values between genders in elderly groups were beyond acceptability threshold. Conclusions The central incisors were getting darker, more yellowish, and reddish with age. Information on the chromatic range of natural teeth by age and gender could help to select colors for esthetic dental restorations. Clinical Significance Dentists should consider an unacceptable color mismatch between the restorations and natural dentition that can occur over time.

“…Studies focusing on the relationship between skin tone and tooth color are sparse and they have not considered overall esthetic attractiveness. Haralur et al and Vadavadagi et al reported that tooth color was correlated with skin shade, recommending evaluating skin shade as a guide in the choice of tooth color. This recommendation has been supported by other studies reporting that people with a darker skin color have teeth with higher value and people with lighter skin color have darker teeth.…”

Objective: The purpose of this clinical study was to determine if skin tone and tooth color had the same influence on smile attractiveness. Materials and Methods:A woman's smile photograph was digitally manipulated to create a range of images with varying colors. The skin shade was modified to create four tones (p1: light, p2: light medium, p3: medium dark, p4: dark) using the L'Oreal True Illusion shade as a guide. The tooth shade was modified in four different tones: A1, A2, A3, A4 using the VITAPAN Classical shade guide to produce 16 images. A sample of 328 participants rated each image for attractiveness by means of a visual analog scale (VAS). Comparison among groups was performed with a 2-way ANOVA adjusted for multiple comparisons with the Bonferroni test (α = .05).Results: Image (p3-a1) showed the highest VAS values, while image (p1-a4) obtained the lowest, (Bonferroni Test: a1 vs a2, a3, a4 P < .001; p3 vs p1, p2, p4 P < .001).Analysis performed for age, sex, level of education, and laypeople/dentists were not statistically significant (P > .05). Conclusions:Variations in tooth and skin tone can significantly influence the perception of smile attractiveness. In the tested conditions, a brighter tooth shade significantly affected the attractiveness of the smile independently from skin tone.Clinical Significance: Understanding patient and dentist perception of the attractiveness of a smile with the important role-played by skin tone, may help clinicians to better identify teeth shade, helping delivery of tailored prostheses and esthetic restorations.
