Root resorption pattern and root length of mandibular primary molars in children: a cross-sectional radiographic study.

ABSTRACT:

Purpose

To determine the root resorption pattern and calculate the root resorption length of mandibular primary molars in children.

Methods

A cross-sectional and descriptive study was conducted of 367 panoramic radiographs of healthy nonorthodontic children, 169 girls with a mean age of 9.39 years and 198 boys with a mean age of 9.02 years. The length of the mesial and distal roots of the primary molar was calculated using a computer program (PixelStick®) that measures the pixels indicated in the image. Student's t test, the Mann‒Whitney U test and the Kruskal‒Wallis test were used for comparisons, and p < 0.05 indicated statistical significance.

Results

A 0.84 mm delay in root resorption of the first mandibular primary molar (74) in boys was described. There was also
