Duration of Growth Spurt based on Cervical Vertebrae Maturation In Indonesia Population

Abstract

Context: Human development consists of periods of accelerated growth where there is an acceleration of
growth followed by a period of slower growth. The timing of pubertal growth spurt and maximal growth
rate during this developmental phase is different in boys and girls. The increase in growth rate in girls
usually occurs at the onset of puberty while boys experience a relatively slow increase in growth rate at
puberty.Aims:to compare the differences in the duration of growth spurtbetween girl andboy in Indonesian
populations in terms of the Cervical Vertebrae Maturation (CVM) seen in the lateral cephalogram. This
information is important to determine the right time and orthodontic treatment plan in order to get maximum
treatment results.
Methods and Material: The research variables were divided into 3 types, namely dependent variables
(chronological age), independent variables (Cervical Vertebrae Maturation stage, gender). Every sample that
met the criteria was performed skeletal maturity analysis using Cervical Vertebrae Maturation (CVM) on
each cephalometric photo Skeletal analysis with Cervical Vertebrae Maturation (CVM) by looking at bone
maturation
Results: There were differences in the mean / mean age of skeletal maturity in terms of changes in CS 3
to CS 4 between male and female samples (p <0.05). The male sample required a duration of age to reach
maturity, namely 15.879 months. Meanwhile, the female sample only required the duration of age to reach
maturity, namely 5,184 months
Conclusions:Girls in this study population had a faster growth spurt duration than boys. This is marked by a
change in the age of skeletal maturity between the two, which is approximately 10 months apart.
