8 mins read Opinions Aesthetic dentistry
Lasers have great potential to improve treatment and are being increasingly used in dentistry. Patients, practice staff and visitors need to be protected from their potentially harmful effects on the skin and eyes, so dental staff need to understand and apply safety principles
