Abstract
1. There are numerous resorption lacunae surrounding the main root canal surface of deciduous teeth. Several odontoblastic processes are different in length, which are found in the periphery of the main root canal. The walls of the main root canal are formed by cementocytes granular in appearance, which are arranged in a spiral fashion.
2. On the surface of the dentin, resorption lacunae are different in size and shape, which overlap each other to form an imbricate pattern. Openings of the dentinal tubles are found within these resorption lacunae. Ovoid or tubular shaped dentinal tubles are arranged regularly with even distance in the floor of the resorption lacunae. Edges of these lacunae are very clearly defined, which protrude as ridges to form circular arcs.
3. On the surfaces of the cementum, resorption lacunae are more or less smaller than those of the dentin. There are some protrusions of cementocyte which are connected to each other to form a granular appearance in the undamaged surface of the cementum.
