Objectives:
Fungiform papillae (FP) contain numerous taste buds. A genetic susceptibility between tasting via FP and caries risk has been suggested. This study aimed to investigate the relationship between FP number and dental caries and to determine whether FP number may be considered as a test for caries risk.
Materials And Methods:
The study included 157 children who attended the pediatric dentistry department at a public university. Questionnaires, including the children's medical health, oral health knowledge, fluoride exposure, and taste preferences, were filled in by their parents. The FP number on the dorsal surface of the tongue was counted according to the Denver Papilla Protocol. Caries was recorded using deft/DMFT indices. Statistical analyses were performed using SPSS.
Results:
The FP number decreased significantly according to age (r = -0.441, p = 0.001), and the mean of the girls' FP number was significantly higher than the boys' (p = 0.022). A greater number of FP was associated with increased deft score (p = 0.02, odds ratio [OR] = 1.164).
Conclusion:
The caries risk increased in children who had more FP (FP > 30); therefore, FP number could be evaluated in terms of caries risk. FP number could be evaluated as a risk factor for determining dental caries since the risk of caries increased after a FP cut-off point of 29 was achieved.
Clinical Relevance:
Clinicians can start preventive treatments for caries earlier by determining the FP number for each child.

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...

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
