          Abstract

          Background

          Facial 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.

          Objective

          The aim of this study was to determine the relationship between skin complexion and tooth value in a Jordanian population.

          Methods

          A 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.

          Results

          A 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.

          Conclusion

          Within 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.

          Accuracy of self-report in assessing Fitzpatrick skin phototypes I through VI.

          Determining Fitzpatrick skin phototypes (FST) allows physicians to assess a person's risk of developing sunburn and, by extension, the need for sun protection to prevent the development of skin cancer. Reflectance spectrophotometry objectively measures the melanin index and can assist in determining the accuracy of self-report of FST compared with dermatologist-determined FST.

            Color: Implications in dentistry

            The success of restorative dentistry is determined on the basis of functional and esthetic results. To achieve esthetics, four basic determinants are required in sequence; viz., position, contour, texture and color. The knowledge of the concept of color is essential for achieving good esthetics. This review compiles the various aspects of color, its measurements and shade matching in dentistry.

              Relationship between tooth shade value and skin color: an observational study.

              There is limited scientific information on the relationship between tooth shade and skin color. This lack of knowledge may impact the ability of the prosthodontist to select artificial teeth that complement the facial complexion of the patient. This observational study explored the possibility of a relationship between tooth shade and skin color. A total of 119 individuals aged 18 to 80 years participated in this observational study. Two investigators calibrated for examining tooth shade performed all examinations. A Vita-Lumin shade guide was used to examine either the maxillary right or left central incisor, one of which had to be restoration- and caries-free for study inclusion. Tooth shades were divided into 4 categories according to value, and skin tones were divided into 4 categories (fair, fair/medium, medium, and dark) with the use of L'Oreal True Illusion compact makeup shades as a guide. Categorical modeling with chi-square analysis and Fisher's exact tests was used to analyze the data (alpha=.05). No interaction among age, skin color, and tooth shade or gender, skin color, and tooth shade was found; however, age was associated with tooth shade (P<.001). Older persons were more likely to have teeth with lower values (darker). Among those aged 60 and older, 85% had teeth in the medium and low range values compared with 17% of those younger than 31. Significant tooth shade differences were discovered among patients with different skin colors (P<.05). Among those with low values (darker teeth), 50% were of fair complexion and 17% were of dark complexion (P<.001). Within the limitations of this study, tooth shade value and skin color were inversely related. Older adults were more likely to have darker teeth (lower value).
