Evaluation of post-bleaching hypersensitivity using desensitizing agent before and /or after in-office bleaching: A randomized clinical trial.

About this activity

In-office bleaching permits close professional control, prevents material ingestion, reduces the total treatment time, and has the potential for quick results, improving patient satisfaction. For this reason, a desensitizing agent is used to decrease the tooth sensitivity that patients experience. The mechanism of action of potassium nitrate remains unknown. This acts by diminishing the excitability of the intra-dental nerve endings and blocking the dentinal tubulesn
