Summary
Methamphetamine use is linked to poor oral health in nonelderly adults, including higher rates of dental caries and periodontitis. These findings suggest dental exams can help identify methamphetamine abuse.
Area of Science:
- Forensic Odontology
- Public Health
- Substance Abuse Research
Background:
- Oral health conditions in nonelderly methamphetamine users are largely unknown.
- Dental caries and periodontitis are common oral health issues.
- This study investigates oral health differences between methamphetamine users and non-users.
Purpose of the Study:
- To compare oral conditions in nonelderly methamphetamine users versus non-users.
- To stratify comparisons by age groups (young and middle-aged adults).
- To identify potential oral indicators for methamphetamine abuse screening.
Main Methods:
- Cross-sectional study using computed tomography images from 3,338 Japanese decedents.
- Participants aged >20 to ≤64 years, categorized as methamphetamine-detected (MA) or control groups.
- Matched pairs (1:4 MA:control ratio) analyzed for DMFT index, periodontitis, and occlusal status.
Main Results:
- Young adult methamphetamine users showed significantly higher DMFT index (14.2 vs 11.0) and periodontitis (39.0% vs 6.8%).
- Methamphetamine users had fewer filled teeth and lower occlusal support compared to controls.
- Similar trends observed in middle-aged adults, with additional missing maxillary incisors in users.
Conclusions:
- Nonelderly methamphetamine users exhibit distinct oral health characteristics.
- These oral conditions may serve as markers for screening methamphetamine abuse during dental examinations.

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...
