Dentin tubules occlusion

"Dentin tubules occlusion" refers to the blockage of open dentinal tubules in teeth to reduce dentin hypersensitivity, a common dental problem. The approach relies on the application of agents that precipitate minerals (such as calcium, phosphate, fluoride, strontium, or related compounds) or resins inside the tubules, physically blocking them to reduce fluid movement and thereby decrease stimulation of intradental nerves. Occluding dentin tubules can provide effective pain relief. It is a clinical strategy, not a specific molecular or receptor target, and various over-the-counter and in-office dental treatments are based on these occlusion mechanisms[1][2][3][5].
