Dental Age Assessment Using Nollaa？？s Method and Skeletal Age Assessment by Hand Wrist Radiograph Among Kashmiri Children- A Comparative Study

Aims and objectives: The Main Purpose of the study was to assess the skeletal age using skeletal maturity indicator and dental age using Nolla’s method and their correlation with each other. Materials and Methods: The study was conducted on 120 healthy children in the age group of 8–13 years, comprising equal number of males and females. The children were radio graphed for hand-wrist of the right & left hand and intraoral periapical X-ray for right permanent maxillary and mandibular canine. Results: A high correlation was observed between skeletal age and dental age by Nolla’s calcification stages for both male and female children of growing age (p value >0.790, 0.64). But Chronological age showed inconsistent correlation with dental and skeletal ages. It was concluded that canine calcification stages given by Nolla’s can also be used for assessing skeletal maturity. Statistical analysis: The quantitative data was analyzed by using one way analysis of variance technique. For comparison of three methods least significant difference post hoc test was used. Conclusion: Nolla’s method of age estimation can be used as a substitute method for skeletal age determination in age group of 8-13 years
