“…According to them, the peak CS3 represented the ideal stage to begin functional jaw orthopedics, as the peak in mandibular growth would occur within the year after this observation. Study by Jamal et al 15 also concluded that skeletal maturation can be reliably assessed with dental calcification stages of permanent mandibular second molar for Nepalese orthodontic patients and the timing of peak skeletal maturation coincides with dental calcification stages F and G for females and stage G for males.…”

Management of skeletal class II relation in growing patient require careful evaluation of growth status, proper diagnosis and treatment plan to address the patient’s need. Twin block is the appliance of choice among functional appliance to correct the skeletal class II malocclusion due to it’s acceptability by the patient and simplified design. Maxillary canine impaction is the second most prevalent impaction after the third molars. Treatment of maxillary canine impaction is usually a challenge to orthodontic approach as the defect lies in the esthetic region of the jaw. This case report describes the orthodontic management of a 9 years male patient having skeletal Class II malocclusion with horizontally impacted maxillary canine. Some modifications in the treatment mechanics are deemed essential to address the patient’s need for achieving the optimal esthetic and to improve the occlusion. Twin block is beneficial for the treatment of skeletal malocclusion in a growing patient to achieve the maximum benefit. The orientation of impacted teeth may change from horizontal to favorable one, hence it should be considered a viable treatment alternative. In such case, early diagnosis and interception at the right time along with radiographic follow-ups are necessary to achieve successful results.

“…Many authors 10 , 13 , 14 , 15 , 17 have also found that calcification stages of the mandibular second molar showed greater correlation with skeletal development than other teeth, as it tends to take longer to develop to a more advanced age, normally presenting apex closure at the age of 16 years. 12 , 17 …”

“…Considering the ethnic variations that influence skeletal development, environmental conditions and regional/climatic variations, 3 , 15 the methods used to evaluate skeletal development and tooth calcification must be tested on different populations. 16 No prior studies have investigated the applicability of the methods in children and adolescents from the northeastern region of Brazil.…”

Objective: This study aimed to establish a correlation between the stages of tooth calcification of mandibular canines and second molars with the phases of skeletal development. Methods: In a consecutive series of panoramic, cephalometric and hand-wrist radiographs of 113 individuals (60 females and 53 males) with an average age of 12.24 ± 1.81 years, the stages of mandibular canine and second molar calcification, cervical vertebrae maturation indicators (CVMI) and skeletal maturity indicators (SMI) were classified. The variables were correlated by means of the Spearman’s Rank test: chronological age, SMI, CVMI and tooth calcification stages. In order to assess whether the CVMI and tooth calcification stages were significant predictors of the SMI, an ordinal regression analysis was carried out. Results: The stages of CVMI (OR = 16.92; CI 95% = 6.45-44.39; p< 0.001) and calcification of the second molars (OR = 3.22; CI 95% = 1.50-6.92; p= 0.003) were significant predictors of SMI, however similar result was not observed for canines (OR = 0.52, CI 95% = 0.18-1.54; p= 0.239). Calcification stage E for boys, and E and F for girls corresponded to the pre-peak phase of pubertal growth. Stages G and H for boys, and F and G for girls coincided with peak of growth. In the final growth phase, the majority of second molars presented with root apex closure (stage H). Conclusion: The stages of calcification of the second molar may be considered predictors of the stage of skeletal development in the population studied.

The assessment of skeletal age is of utmost importance not only in the field of anthropology, forensic medicine, pediatrics, endocrinology but also in orthodontics and jaw orthopedics. Bone age refers to the individual’s biological development which can differ within a relatively wide range for the same chronological age. Therefore, accurate assessment of skeletal maturity and pubertal growth plays an important role in establishing a diagnosis for certain diseases. In addition, it is essential for proper timing and success of treatments in many cases. Currently, there are many methods available to determine skeletal age and pubertal growth spurt. During growth, bones undergo significant changes, the sequence of which is strongly determined. These changes can be measured by various methods including radiological examinations. More specifically, these classical methods are often based on the radiological evaluation of morphological changes in the hand bones and cervical vertebrae. Methods based on dental development also exist to assess the biologic maturity of an individual. However, thanks to three-dimensional imaging techniques and molecular diagnostic methods, even more accurate tests can be performed to determine biological maturity. These modern methods rely on the information obtained from the cone-beam computer tomograph records and on the measurements of biomarkers present in different circulatory or other body fluids. The purpose of this summary is to provide an overview of the various classical and modern methods for the assessment of skeletal age that could aid us in many fields of science.
