Skeletal Maturity Indicator
Write a short note on the skeletal maturity indicator.
Answer. Various skeletal maturity indicators are:
- Hand wrist radiographs: For details,
- Skeletal maturation evaluation by using cervical vertebrae:
- Tooth mineralization as an indicator of skeletal maturity

Tooth Mineralization as an Indicator of Skeletal Maturity
Dental development is widely investigated as a potential predictor of skeletal maturity level.
The ability to assess skeletal maturity by developmental stage of dentition via the examination of panoramic radiograph offer various advantages over the conventional hand–wrist radiographic method
Demerjian, Goldstein, and Tanner describe tooth mineralization as an indicator of skeletal maturity.

Dental Calcification Stages Using Demerjian Index (DI)
- Stage A: Calcification of the single occlusal point without fusion of different calcifications.
- Stage B: Fusion of the mineralization points, now the contour of the occlusal surface is recognizable.
- Stage C: Formation of enamel is completed at the occlusal surface, and dentine formation is commenced. Pulp chamber is curved and no pulp horns are visible.
- Stage D: Completion of crown formation to the level of the cementoenamel junction. Commencement of root formation. Pulp horns begin to differentiate, walls of the pulp chamber remain curved.

- Stage E: The Length of the root remains shorter as compared to the height of the crown. Walls of the pulp chamber are straight and pulp horns become more differentiated than in previous stages. In molars, the root bifurcation starts to calcify.
- Stage F: Walls of the pulp chamber form an isosceles triangle, and the root length is equal to or greater than crown height. The development of bifurcation in molars is sufficient to give roots a distinct form.
- Stage G: Walls of the root canal are now parallel, apical end is partially open. In molars, only the distal root is rated.
- Stage H: Complete closure of root apex. The periodontal membrane surrounds the root and apex and is uniform in width throughout.
