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...

Tooth Anatomy

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...

Area of Science:

Audiology
Dental Medicine
Public Health

Background:

Existing research suggests a link between hearing loss and tooth count.
The impact of tooth loss treatment on hearing remains unclear.

Purpose of the Study:

To investigate the association between hearing loss and natural tooth count.
To examine the relationship between hearing improvement and dental implants.

Main Methods:

Analysis of data from the 8th Korea National Health and Nutrition Examination Survey (2020-2021).
Inclusion of participants with audiological results, natural tooth count, and dental implant data.
Categorization into normal hearing, mild hearing loss, and moderate hearing loss groups.

Main Results:

A higher number of natural teeth and dental implants correlated with normal hearing.
A significant linear decrease in hearing level was observed with fewer natural teeth and dental implants.
Statistical significance was maintained after adjusting for confounding factors (P < .001).

Conclusions:

Hearing loss is significantly associated with tooth loss.
Dental implants show a positive relationship with improved hearing thresholds.
Monitoring tooth loss may aid in managing hearing loss, especially sensorineural types.
