Objectives:
The present study was set up to explore (1) a potential association between a person's caries risk profile and the presence or absence of root-filled teeth, and (2) the caries risk in endodontically treated teeth.
Study Design:
Two hundred Saudi adults were divided into an Endodontic Group (EG; n = 100), with a minimum of 2 root-filled teeth, and a Non-Endodontic Group (NEG; n = 100), without any root filling. Various caries risk factors were evaluated using a computer-based program (Cariogram). Clinical and radiographic examinations were also carried out.
Results:
Cariogram findings showed that "the chance of avoiding caries" was low in both groups (35% in EG and 37% in NEG), and there was no statistically significant difference between the 2 groups. However, DMFS, recurrent caries, and mutans streptococcus count in saliva were significantly higher in the EG compared to the NEG (P < .05). When teeth in the EG were evaluated independently, the proportion of recurrent caries to the total fillings associated with endodontically treated teeth was 31.6% versus 19.2% in the non-endodontically treated teeth.
Conclusions:
Data were not in favor of an association between caries risk profile and presence of root-filled teeth, but supported the notion that root-filling procedures might make the tooth more susceptible to caries.

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...

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.
