Association Between Weight and Height of Children and Eruption of Permanent Teeth in Mosul City Center-Iraq


Aims: To evaluate the effect of length and weight of 5–13 years old children on eruption of permanent teeth in Mosul City. Materials and Methods: The sample consisted of 894 children and teenagers; 412 males and 482 females ranging in age from 5–13 years. A tooth was defined as erupted when any part of its crown pierced its gingiva. The sample was divided into 4 age groups: Group 1: 250 child and teenager aged 5–<7 years; group 2: 248 child and teenager aged 7–<9 years; group 3: 257 child and teenager aged 9–<11 years; and group 4: 139 child and teenager aged 11–13 years. Other information were also recorded including length of child (in meters) and weight of child (in kilograms). Results: The number of erupted teeth according to individual tooth, gender and age groups was recorded. There was a strong correlation (p = 0.001) between length and weight of children on one hand and number of erupted teeth on the other hand. Conclusion: Children who had higher weight and length accelerated dental development.
