Abstract:- Introduction: Twins are of two types, monozygotic and dizygotic and the status of development of a child is usually assessed in relation to events that take place during progress of growth. Thus chronological age, dental development, height and weight measurements, sexual maturation characteristics and skeletal age are some biological indicators that have been used to identify time of growth. The objective of the study was to assess the correlation between the chronological age, dental age and skeletal age among twins of different types. Materials & methods: Panoramic and hand wrist radiographs of 30 twins between 8-16 years of age were evaluated and compared for correlation of dental, skeletal and chronological ages. Results: The result indicated that correlation exists between all three above characteristics among twin pairs of the same zygosity and sex, but no correlation exits between different zygotic twins and twins of different sex. Conclusion: There is Correlation between chronological age; dental age and skeletal age among monozygotic and dizygotic twins of the same sex whereas, no correlation exists between mixed sex pair twins. Keywords:- Monozygotic, dizygotic, panoramic, hand wrist radiographs.
