Abstract

Aim:

The objective was to evaluate the bone mineral density (BMD) and bone mineral content (BMC) in children affected with molar incisor hypomineralization (MIH) using dual-energy X-ray absorptiometry (DEXA) scan.

Materials and Methods:

The study comprised a total of 30 children aged 6-10 years. Fifteen children were affected with MIH (moderate and severe variety) diagnosed using the European Academy of Paediatric Dentistry 2003 criteria, and remaining 15 children not affected with MIH serve as a control group. DEXA scan was done in all the selected children under standard conditions.

Results:

A positive association was seen between childhood illness and MIH. The mean subtotal BMC (grams) in MIH and control group was 633 ± 80.05 and 670.33 ± 166.41, respectively, whereas mean subtotal BMD (g/m2) was 1.00 and 0.87 ± 0.35, respectively, with no statistically significant difference between two groups. BMD and BMC at the lumbar spine and thoracic spine locations were also did not vary significantly between MIH-affected children and controls.

Conclusion:

Childhood illnesses were more common in MIH-affected children compared to controls. Bone maturation parameters (BMD, BMC) do not differ between MIH affected and control children.
