DISCUSSION

In this study, the usefulness of dental maturation assessment as a diagnostic test using panoramic radiographs as an approach to determine skeletal maturation was explored, with a reliable methodology.

A significant positive correlation between dental and cervical maturity was obtained for both genders. This is consistent with correlations found in several other publications 12,18–21,23,24. As Sukhia and Fida conclude in their 2010 study, having this correlation makes it posible to use dental maturity to assess skeletal maturation 25.

The area under a ROC curve represents accuracy of a diagnostic test and it is defined as the probability of correctly classifying a pair of healthy and sick individuals 26. In this case, areas …show more content…

That means that between dental stages A and E the individual would be in a pre growth spurt phase and during stages F through H in a post growth spurt phase. In practice, once the left mandibular second molar has developed its furcation enough to show the radicular shape and the root length is equal or grater than the crown height, the patient has already surpassed the peak in pubertal growth velocity. This means that the individual is either in the deceleration of growth in the post-peak stage of the pubertal growth spurt, or he/she actually concluded the pubertal growth spurt.

In the table that resumes the assessment of this diagnostic test, the prevalence is the probability to find an individual aged 5 to 15 years old that already has gone through his o her growth spurt, being 11% and 26% respectively. Sensitivity, which is the ability to identify a post pubertal growth spurt individual when having a dental stage F, G or H is 87% for females and 97.1% for males. Specificity, the ability to identify that has not gone through pubertal growth spurt yet when having a dental stage A to E, is 82.9% for females and 72.3% for …show more content…

PPV es defined as the probability of being healthy when the diagnostic test gave a negative result 28. In this study, it means that the chances of a patient not being in a post growth spurt yet while having a dental stage A to E es high. This is relevant because knowing accurately when the patient has not gone through his or her growth spurt, improves dentofacial orthopedic treatment planning and
