Aim: To determine the morphology and mineralization of Sharpey's fibers in bundle bone of humans with reference to interdental area­ Method: Human interdental alveolar bone between mandibular 1st and 2nd molar teeth was taken and observed under scanning electron microscope (SEM) and the constituent elements were analyzed using energy dispersive X- ray spectroscopy (EDS). Result: Under scanning electron microscope, the Sharpey's fibers were fully mineralized and appeared as dome shaped projections in the crestal region where as in the apical region, they remained unmineralized at the centre and appeared as depressions- The results of the energy dispersive spectroscopy supported the above findings­ Conclusion: The degree of mineralization decreases from crestal to apical region, indicating that, the periodontal ligament which supports the teeth matures from apical to crestal and It is fully developed in the crestal region­
