Summary
Tooth shade selection is crucial for patient satisfaction. This study found lighter tooth shades are common across all skin tones, but teeth darken with age, and females tend to have lighter shades.
Area of Science:
- Dentistry
- Aesthetic Dentistry
- Dental Materials
Background:
- Tooth shade selection significantly impacts patient perception and prosthesis acceptance.
- Dental literature suggests using patient demographics like age, sex, skin, hair, and eye color for shade matching when records are unavailable.
Purpose of the Study:
- To determine the prevalence of common tooth shades in relation to skin color.
- To investigate the relationship between tooth shade, age, and sex.
Main Methods:
- A descriptive cross-sectional study was conducted with 338 participants.
- Tooth shades were assessed using the Vitapan Classical Shade guide.
- Skin color was determined using the Revlon Foundation Makeup Shade guide under natural daylight.
Main Results:
- Lighter tooth shades (high value) were prevalent across fair, medium, and dark skin tones.
- The most common tooth shade in fair and medium skin tones was B1, while B2 was most common in dark skin tones.
- Individuals aged 10 to 35 years exhibited lighter tooth shades.
Conclusions:
- Lighter tooth shades are common regardless of skin tone.
- Tooth shade does not correlate with skin tone but darkens with age.
- Females tend to have lighter tooth shades compared to males.

Changes in Skin Color: Clinical Perspectives
3.2K
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...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Pigmentation
4.0K
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...

Cross-Sectional Research
12.2K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Teeth
1.5K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Assessment of the Mouth
879
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
