Tooth Shade and Skin Colour: A Descriptive Cross-Sectional Study

Abstract

Introduction: Selection of proper tooth shade is one of the most significant factors influencing patients’ aesthetic perception and improved prosthesis acceptance. Guidelines in the dental literature suggest age, sex, colour of skin, hair and eye for selecting tooth shade when past records cannot be obtained. The objective of the study was to observe the most common tooth shade in relation to the skin colour and the prevalence of the same in relation to age and sex.
 Methods: A descriptive cross-sectional study was carried out at Kathmandu Medical College from June to August 2019. Vitapan Classical Shade guide was used to select the shade of upper right central incisorin 338 participants. Revlon Foundation Makeup Shade guide was used to determine colour of skin. Participants were examined without facial makeup. Skin colour and teeth shade were examined in daylight at about sametime of the day. Data obtained were computed and analysed using Microsoft Excel 2016 software.
 Results: Prevalence of tooth shade with high value (lighter shade) was seen in all fair (121, 35.8%), medium (63, 18.6%) and dark skin tones (23, 6.8%). Most common teeth shade in fair individuals was B1 (47, 37.9%), in medium also B1 (25, 7.4%) and dark was B2 (9, 2.7%). Age range of 10 to 35 years had tooth shade with higher value (159, 47.04%).
 Conclusions: Hence, teeth shade with high value (lighter shade) was prevalent in skin tone of all types in current study. Skin tone was not related to teeth shade selection, teeth became darker with age and females had lighter teeth shade (high value).

Modeling the Relationship Between Tooth Color and Skin Color in Equations to Predict Tooth Color

“…Some previous studies that investigated the relationship between tooth color and skin color used conventional shade matching with a makeup skin color chart/shades [ 1 , 7 , 17 ], or Fitzpatrick skin type test [ 18 ], and a conventional tooth color selection using tooth shade tabs. These studies concentrated on and described color according to the relationship between the lightness (value) of the tooth with the lightness (value) of the skin.…”

“…Achieving an aesthetically pleasing smile is among the difficulties dentists must overcome. Harmonizing the surrounding facial structures, such as hair, complexion, and eyes, as well as age, with the color of the teeth was seen as a difficult problem [ 1 , 2 ]. Choosing tooth color is subjective with no set processes or protocols to follow.…”

Does age determine the lightness and darkness of tooth shades? A retrospective study

“…However, other factors such as gender and skin complexion should also be associated with tooth shade to provide a more lifelike prosthesis for the replacement of anterior and posterior teeth. [ 20 21 ] Furthermore, the various other shade guides affect the determination of tooth shade. [ 22 23 24 ]…”

Tooth Shade Relationship with Age, Gender, and Skin Color in a Saudi Population: A Cross-Sectional Study

“…Jahangiri et al concluded that 50% of persons with low-value teeth had fair skin, whereas 17% had dark skin [6]. However, a study in Nepal [13], and another in India [14], exhibited no difference between all skin colors and tooth shades. Another study conducted in Korea reported that lighter and less chromatic central incisors were characteristics of female subjects in all age groups [15].…”
