In vitro, it blocks 92% of dentinal tubules in as little as six rinses, according to Listerine’s research by Johnson & Johnson. The formula includes potassium oxalate crystal technology. Crystals are deposited on the dentine and deep inside exposed open tubules. The crystals build with each rinse to provide a deep stable comprehensive tubule occlusion.
Susie Sanderson OBE spoke at the launch. She is a wet-fingered health service dentist in Sheffield. She talked about the different types of patients who present and described typical sensitivity pain. She explained how she diagnoses by exclusion.
Hygienist Sally Simpson talked about treating patients with sensitive teeth and treating patients with periodontal disease which is frequently teased out of the patient during ultrasonic debridement and mechanical debridement. She said: ‘For me, treatment of periodontal disease comes hand in hand with handling sensitivity.’
Dr Roberto Labella from Johnson & Johnson launched this new product for the management of dentinal sensitivity. He explained that the potassium oxalate at 1.42% is the active ingredient in the mouthwash. Research shows the product is four times more effective at blocking tubules than leading other mouthwashes and 30% more effective than toothpaste after just six rinses.
Research by J&J showed the product can withstand the typical daily challenges of mechanical and acid exposure. This was tested by measuring dentinal tubule occlusion. Research in clinical trials in vivo showed it to be 91% more effective at reducing sensitivity pain at two weeks than another leading potassium nitrate toothpaste. It is recommended for use twice daily for 60 seconds a time after brushing, fitting into the recommended typical daily oral hygiene routine.
