Background
Growth incidents usually progress in a fairly expected sequence; however, their timing and pattern vary across individual subjects. Biochemical biomarkers have an association with bone metabolism and produce signals which stimulate the growth and development of various craniofacial structures. Steroid dehydroepiandrosterone sulfate (DHEA-S) plays a major role in the initiation of growth hormone actions which has a significant role in promoting and accelerating skeletal maturation during puberty. The
Conclusion
Salivary DHEA-S can be used as a non-invasive indicator for detecting the pubertal growth spurt.
Methods
One hundred forty-one participants (70 males and 71 females), between 7 and 23years of age, were categorized into six cervical stages (CS) based on lateral cephalograms. Using a passive drooling technique, unstimulated whole saliva samples were collected from all enrolled subjects. DHEA-S levels were analyzed using the enzyme-linked immunosorbent assay (ELISA) and correlated with the six CVM stages.
Results
One-way analysis of variance ANOVA showed that the mean salivary DHEA-S levels at CS 3 and CS 4 were significantly different from the values recorded at other stages, and the two stages were statistically significant from each other. Pearson linear correlation of mean salivary DHEA-S levels from CS 1 to CS 6 showed a significant positive correlation.
