Summary
Dental calculus and caries can form simultaneously on dentin surfaces. This in situ study demonstrates concurrent formation, impacting the understanding of dental plaque interactions with hard tissues.
Area of Science:
- Oral biology
- Dental research
- Biomineralization
Background:
- Dental caries and calculus are common oral conditions.
- Understanding their simultaneous formation is crucial for effective prevention and treatment strategies.
Purpose of the Study:
- To investigate the concurrent formation of dental calculus and dentin caries.
- To assess this phenomenon using an in situ model over short time periods.
Main Methods:
- An in situ dentin caries model was used with human volunteers.
- Specimens were exposed to sucrose solution and fluoride mouthwash for up to 14 days.
- Analysis included stereomicroscopy, SEM, energy dispersive spectroscopy, and fluorescence spectroscopy.
Main Results:
- Dental calculus formed concomitantly with caries on both carious and non-carious dentin specimens.
- Calculus was detected across all time intervals (2, 5, 9, and 14 days).
- Calculus Ca/P ratios ranged from 1.1 to 1.7, with fluorescence confirming deposits on carious surfaces.
Conclusions:
- Concomitant formation of dental caries and calculus is possible in dentin.
- This finding has significant implications for studying surface phenomena at the interface of dental tissues and plaque.

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...

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...
