Age Related Prevalence of Pre-Eruptive Intracoronal Radiolucent Defects in the Permanent Dentition
Objective:
The present study aimed to determine if the prevalence of pre-eruptive intracoronal radiolucent defects is higher for young age groups, in which there are more unerupted teeth.
Study Design:
A retrospective study of panoramic and bitewing radiographs was conducted. An inclusion criterion was the presence of un-erupted permanent teeth with a formed and clearly visible crown. Age groups were: young (6-8 years), intermediate (9-12 years) and adults (13-53 years). Significance level was set at p≤0.05.
Results:
Thirteen (3.9%) pre-eruptive lesions were detected in 335 records. No lesions were found in the young group (7.4%), in the intermediate and adult age groups six and seven lesions were found, respectively. In most cases the pre-eruptive lesion was found in a third molar.
Conclusion:
The prevalence of pre-eruptive intracoronal lesions was not higher for young age groups. The prevalence of pre-eruptive intra coronal radiolucent lesions is 3.9%, irrespective of age.

Teeth
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...
