Abstract:
This work aimed to further evaluate the association of MMP20 rs1784418 C>T and dental caries experience with the hypothesis that MMP20 rs1784418 C>T is a risk factor for dental caries. 184 children 4-7 years of age had their caries experience determined and buccal cheek swabs collected for DNA extraction to test for association with the MMP20 rs1784418 C>T using standard statistical approaches. A meta-analytic approach was also implemented to compile previous discrepant reports of the same association. We found an association between MMP20 rs1784418 C>T and dental caries experience in primary dentition (p = 0.01). The meta-analysis showed that this association appears to favor individuals born in Brazil and not Turkey. MMP20 rs1784418 C>T appears to protect against dental caries, but its effects are likely to be more marked in certain populations.

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 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...
