Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
Mate Choice01:20

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
Socioemotional Experience and Gender Development01:30

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
The Representativeness Heuristic02:13

The Representativeness Heuristic

The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.
Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Area of Science:

  • Dental materials science
  • Human perception and cognition

Background:

  • Accurate shade matching is crucial for esthetic dental restorations.
  • Factors influencing shade matching accuracy, such as gender and experience, require further investigation.

Purpose of the Study:

  • To investigate the effect of gender on dental shade matching quality.
  • To determine if the level of professional experience influences shade matching accuracy.

Main Methods:

  • A cross-cultural study involving 614 color-normal participants (305 female, 309 male) from 15 universities in 9 countries.
  • Participants underwent training using specialized software (Toothguide Trainer and Toothguide Training Box).
  • Shade matching ability was assessed by comparing participants' selections to 15 shade guide tabs, with scores calculated as the sum of color differences (SigmaDeltaE(ab)(*) score).

Main Results:

  • The overall mean shade matching score was 41 (±21).
  • Female participants achieved significantly better scores (38 ±20) compared to male participants (44 ±21) (p<0.001).
  • No statistically significant difference in shade matching scores was found between dental students (42 ±20) and dental professionals (39 ±21).

Conclusions:

  • Gender is a significant factor influencing dental shade matching performance, with females demonstrating superior accuracy.
  • The level of experience in dentistry does not appear to be a determining factor in shade matching ability.
