Relationships between mandibular canine calcification stages and skeletal maturity

Diagnostic reliability of mandibular second molar maturation in the identification of the mandibular growth peak: A longitudinal study

“…The longitudinal study design has been previously used to evaluate diagnostic reliability of other growth indicators, 5,18 but it has never been used to study their relationship to dental maturity. Moreover, while previous studies correlated dental maturation stages with other growth indicators such as CVM 8,14,16,[23][24][25][26][27] or HWM, 12,24,28 the present study focused, for the first time, on the mandibular growth peak itself. The present results showed that none of the maturational stages of the mandibular second molar reach satisfactory diagnostic reliability to consistently identify the mandibular growth peak, irrespective of the sample of origin.…”

“…29 One of the reasons underlying this noteworthy lack of relevant data on diagnostic reliability may be the difficulty of performing such analysis from longitudinal data in a subset of selected subjects, all with a predetermined condition (mandibular growth peak) or a diagnostic outcome (a given dental stage). 5,18 Previous studies 8,12,14,16,[23][24][25][26][27][28] investigating the predictive reliability of dental maturation did not evaluate mandibular growth directly but instead used other growth indicators, thus reporting only indirect evidence of any correlation between dental maturation and the mandibular growth peak. This is of particular relevance considering that growth indicators such as CVM 18 and others 3,5 are not suitable for the correct identification of the mandibular growth peak in all subjects.…”

Skeletal maturity assessment using mandibular canine calcification stages

“…Among all the tested teeth, mandibular canines showed a significant association with the stages of development (17)(18)(19)(20)(21). In addition, hypodontia of permanent canine is extremely rare, and the prevalence ranges from 0.18 to 0.29% (22).…”

“…Some studies report high correlations between calcification stages of teeth (dental maturity) and skeletal maturity indicators (13)(14)(15)(16). Some authors investigated correlations between calcification stages of some teeth (canines, second and third molars), and they found that the calcification stage of mandibular canine showed a significant correlation with skeletal maturity (17,18,21). In this study, the correlation coefficients between calcification stages of mandibular canine and skeletal maturity were 0.895 for male and 0.701 for female subjects, and all correlation coefficients were statistically significant, at p<0.001.…”

“…Stages of teeth development are associated with growth and development, which means that dental maturity may be used as a parameter for assessment of skeletal maturity, as has been shown by numerous studies (13)(14)(15)(16). Some authors noted that the developmental stages of certain teeth, for example canines (17,18) and second molars (19), show a high correlation with skeletal maturity.…”
