Summary
Iranian adults are willing to pay more to preserve natural anterior teeth than posterior teeth. Sociodemographic factors significantly influenced their willingness to pay for dental preservation over extraction.
Area of Science:
- Oral Health Economics
- Dental Public Health
Background:
- Willingness to pay (WTP) for health benefits reflects perceived value.
- Understanding WTP for natural tooth preservation is crucial for public oral health policy.
Purpose of the Study:
- To determine the WTP of healthy Iranian adults for preserving natural teeth versus extraction.
- To analyze WTP for anterior and posterior teeth separately.
Main Methods:
- Cross-sectional study with 795 participants in 2021.
- Four treatment scenarios presented; WTP assessed for anterior/posterior teeth, painful/painless conditions.
- Two-stage hurdle model used to identify influencing factors on WTP.
Main Results:
- Over 65% preferred tooth preservation; mean WTP was highest for preservation (up to $94) and lowest for extraction without replacement ($19).
- WTP was consistently higher for anterior teeth treatment compared to posterior teeth.
- Higher education, employment, income, older age, private practice preference, and female gender (mostly) positively influenced WTP.
Conclusions:
- The average WTP for treating compromised teeth was below typical dental fees, yet most preferred preservation.
- Anterior teeth preservation commands a higher WTP than posterior teeth, irrespective of pain or treatment type.
- Sociodemographic factors are primary drivers of WTP decisions, with implications for policymakers and insurers.

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...

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...
