Dentin tubule and tooth enamel surface

The dentin tubule is a microscopic channel within the dentin layer of a tooth, extending from the pulp chamber to the dentinoenamel junction[1][2][3]. These tubules carry fluid and nerve processes, transmitting sensory stimuli (e.g., temperature, pressure) to the dental pulp and are implicated in tooth sensitivity[8]. The tooth enamel surface is the highly mineralized, acellular layer covering the crown of the tooth, composed primarily of hydroxyapatite. It acts as the primary protective barrier against physical and chemical insults, preventing decay and wear[5]. The interface between the dentin tubules and enamel surface plays a crucial role in the structural integrity and sensory function of teeth. In summary, "Dentin tubule/Tooth enamel surface" describes anatomical features rather than a therapeutic molecular target or receptor, making this entry incorrect as a drug target.
