Context:
The assessment of dental age is useful in the planning of orthodontic treatment, in pediatric dentistry, pediatric endocrinology, and forensic medicine. It is essential for a pediatric dentist to formulate treatment plan and it is a source of complementary information for pediatrician. Changes in the body proportion and composition are the essential elements of growth, especially maturation.
Aims:
The present study was aimed to correlate the chronological age, dental age, and body height in children from Pune region of Maharashtra, India.
Subjects And Methods:
: Four hundred and thirty-one panoramic radiographs of 177 boys and 254 girls in the age group of 4-14 years were obtained. Chronological age was assessed by recording date of birth. Dental age assessment was done using orthopantamogram following the method described by Demirjian. Body height was recorded using a measuring tape.
Results:
Chronological age and dental age showed significant positive correlation between male and female sample, i.e., r = 0.905 for males and r = 0.901 for females. Statistically significant correlation was observed between calculated dental age and body height.
Conclusions:
In the present study, it can be concluded that the Demirjian method of dental age assessment showed high accuracy when applied to pediatric population in Pune.

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...

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...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
