Teeth

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 and...

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

This study found significant color differences between natural and artificial teeth in partial denture wearers. Artificial teeth often do not match natural tooth color, impacting aesthetic harmonization.

Area of Science:

  • Dentistry
  • Prosthodontics
  • Dental Materials

Background:

  • Achieving natural aesthetics in partial dentures requires careful tooth color selection.
  • Discrepancies between natural and artificial tooth shades can lead to patient dissatisfaction.

Purpose of the Study:

  • To investigate the differences between natural tooth color and the color of artificial teeth used in partial dentures.
  • To establish criteria for improved color harmonization in prosthodontic treatments.

Main Methods:

  • Natural tooth color was measured using a dental color measurement apparatus and the VITA classical shade guide.
  • Artificial tooth color data was collected from medical records of partial denture patients.
  • Color distribution analysis was performed using the Fisher exact test.

Main Results:

  • Natural tooth colors were most frequently C-type (39%), followed by D-type (32%), A-type (22%), and B-type (7%).
  • Artificial teeth were predominantly A-type (97%).
  • A significant difference was observed in color distribution between natural and artificial teeth.

Conclusions:

  • The color of artificial teeth in partial dentures did not harmonize with the natural teeth of the wearers.
  • Current practices may not adequately address the aesthetic needs for natural tooth color matching in partial denture fabrication.
