Guided biofilm therapy (GBT): The future of dental hygiene?
For those who may not know, guided biofilm therapy is (GBT) is a less invasive way of doing dental hygiene. GBT reduces the amount of instrumentation used, and it focuses more on biofilm management.
Maryam Shamuel came across an office that practices GBT when she moved to Las Vegas a few years ago. During her search for an office that aligned with her priorities, she noticed some that stressed GBT. She was hired in one, and has been a fan of GBT ever since.
She and Annie Walters agree that GBT is the direction of today's dentistry. It's less invasive, it brings back disclosing, it makes oral hygiene instruction more interactive, and it encourages patients to be more proactive in their home care.
All of these reasons make GBT more comfortable for patients and places less strain on clinicians. It gives clinicians more time during each appointment to perform other necessary protocols, such as oral cancer screening and taking the patient's blood pressure, raising the level of care provided.
Maryam explains that GBT removes the root cause of inflammation, and she believes it makes hygiene more enjoyable all around.
Tune into Maryam's and Annie's discussion to learn whether GBT is right for your practice.
