Abstract

Introduction Injuries to the neurovascular structures leading to various complications are a common .n clinical practice. Such injuries can lead to abolition of different types of sensations. In dental practice, the administration of local anaesthetics can cause damage to the nearby nerve leading to neuropathy or loss of particular sensation carried by that nerve. Consciousness of sensations can be achieved only when the impulses reach the higher centres in the cerebral cortex. Therefore, the knowledge of the sensation pathways from the receptors to the higher centres is of utmost importance for the interpretation of the level of injury. Unfortunately, simple areas like sensory pathways of oral structures and taste remain to be debatable for the learners.Conclusion Different text books of Anatomy and Physiology describe the 2 nd order neurons of these sensation pathways differently. Considering this, we have discussed the different contradicting views expressed by different authors. These contradictions may create confusion and difficulties for the learners and more so for the dental practitioners.
