Evaluation on the Growth of Trabecular Pattern Using Bite-wing Dental X-ray Films

Abstract

The growth of the trabecular pattern was evaluated using bite-wing dental x-ray films which were taken during a regular dental check up.
The results were as follows:
1. It was revealed that the correlation value of the trabecular pattern decreased to about 60 per cent by 9 years of age, after 10 to 14 years of age, the trabecular pattern increased to about 90 per cent.
2. The modulation transfer function was confirmed in the area of low frequency in 6 to 9 year olds, but it moved to the area of high frequency with aging. These suggested the matrix area of the trabecular pattern increased and another vacant area decreased with aging.
