Face and Neck Dermatitis from a Stainless Steel Orthodontic Appliance
Nickel allergy Orthodontics
2010/3/9
Although nickel is the most common cause of contact allergy, nickel-containing orthodontic appliances seldom cause adverse reactions that result in discontinuation of treatment. We report on an erupti...
Objective: To explore whether patients' pain experiences and orthodontists' assessments of their patients' pain levels are consistent and whether orthodontists are aware of their patients' use of pain...
