Dipotassium oxalate and diode laser for dentinal hypersensitivity

Dentin hypersensitivity (DH) is a widespread dental issue characterized by sharp pain due to exposed dentinal tubules (DT) responding to stimuli. Effective management involves occluding these tubules to reduce fluid movement, which triggers pain. This study helps to analyze the efficiency of an 810 nm diode laser in conjunction with a mouthwash containing 1.4% dipotassium oxalate in the occlusion of DT.

Methods

Samples: 40 dentin samples from extracted human third molars were used.
Groups:
	Group 1: Control (no treatment).
	Group 2: Dipotassium oxalate mouthwash applied for 5 days.
	Group 3: Mouthwash + 810 nm diode laser.
	Group 4: Diode laser alone.
Assessment: Tubule occlusion was analyzed using scanning electron microscopy (SEM).

Results

Control Group:
Limited DT occlusion (2.76% mean occlusion).

Mouthwash Group: Significant DT occlusion (97.06%).
Green circle represents the occluded tubule whereas, open tubules (represented with red circle) are more in number

Laser Group: High occlusion (99.58%).
SEM micrograph of dentin surface after treatment with an 810 nm diode laser. Red circle represents the partially open tubule whereas, occluded tubules (represented with green circle) are more in number

Combination Group: Highest occlusion (99.91%), with no open tubules observed.
SEM micrograph of dentin surface after application of a combination of a mouthwash with a 1.4% dipotassium oxalate and an 810 nm diode laser. No open tubules can be observed.

Conclusion
	Mouthwash with dipotassium oxalate and diode lasers effectively occlude dentinal tubules.
	Dipotassium oxalate mouthwash forms calcium oxalate crystals, occluding DT.
	Diode lasers assist by modifying dentin surfaces through thermal effects.
