Aim:The aim of the study is to evaluate radiographically the development of mandibular 1st molar development based on nollas stage of tooth development in 3-6 year old female children.
Materials And Methods: The study includes 8 female children of age 3-6 years. The data was collected from patients records and the data was analysed betweenjune 2019 and march 2020, Saveetha Dental College And Hospital,Chennai. Data was recorded by evaluating IOPA and OPG of 36 and 46. After the evaluation based on nollas stages the values were tabulated and documented. The data was then transferred to SPSS software and chi square test was performed to evaluate the significance.
Results: In this study molar development in 3-6 years female children was maximum at the age of 6 years. Lower left molar showed a faster rate of development. When dental age is compared to the nollas stage maximum maturation was present at stage 9 of nollas stage of tooth development.
Conclusion: From the study we can conclude that Nollas method can be used to assess the dental maturity. It can be used as an adjunct to the radiological examination for calcification of teeth.
