Objectives:
The study aimed to determine the relationship between the eruption timing of permanent teeth and anthropological assessments (height and weight) in children from Chennai, India.
Materials And Methods:
A cross-sectional study was designed, and 12650 children were selected using a multistage random sampling method. The clinical eruption status of all permanent teeth was evaluated using a novel grading system, and correlational analysis determined the relationship between height/weight and tooth eruption age.
Results:
The study found statistically significant associations between tooth eruption ages and both height and weight. While the correlation for height was weak and non-significant (r = -0.023 to 0.151, including zero), the correlation for weight was more pronounced (r = 0.044 to 0.519).
Conclusion:
The study suggests that both height and weight are significantly associated with tooth eruption ages, but weight has a stronger and more consistent influence. Individuals with obesity tend to experience delayed tooth eruption.

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...
01:09Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
