Summary
This study identified reasons for permanent tooth extraction in Taiwan. Dental caries and periodontal disease were the primary causes, with third molars most frequently extracted.
Area of Science:
- Dentistry
- Oral Health
- Public Health
Background:
- No prior studies in Taiwan have investigated the reasons for permanent tooth extraction.
- Understanding extraction reasons is crucial for public dental health strategies.
Purpose of the Study:
- To determine the primary reasons for permanent tooth extraction in Taiwan.
- To analyze extraction patterns across different age groups and tooth types.
Main Methods:
- Secondary data analysis of the 2009 National Health Insurance Research Database.
- Inclusion of 4,958 dental visits coded for extraction from 4,811 patients.
- Analysis of extraction reasons, age distribution, and tooth types.
Main Results:
- Dental caries was the leading cause of extraction (55.3%), followed by periodontal disease (22.1%).
- Caries-related extractions occurred across all age groups; periodontal disease extractions increased after age 35.
- Maxillary and mandibular third molars were the most frequently extracted teeth, due to caries and impaction, respectively.
Conclusions:
- Dental caries and periodontal disease are the predominant reasons for permanent tooth extraction in Taiwan.
- Age influences the prevalence of extraction reasons, with periodontal disease becoming more significant in older adults.
- Third molar prevalence in extractions highlights the need for targeted preventive and surgical interventions.

01:15Teeth
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...

01:21Tooth 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.
