In a dental practice there is sometimes too much to do for one assistant, even two assistant. Well if you have not checked this out you should: www.isolitesystems.com . It is like an extra set of hands, retracts the cheek, keeps the tongue out of the way, allows the patient the comfort of a bite block to rest on, lights you field of vision( light adjusts to prevent curing of materials permaturely) and has great suction in it. I have one practice I work with that lost a chairside assistant , got the Isolite and still have not hired back the second assistant. Just a thought for those of you who may need a little more help chairside. It works great in hygiene also if you are doing the sealants in your office.
