Skin problems in dentists and dental technicians

Author: Brian Wu PhD. MD Candidate, Keck School of Medicine, Los Angeles, USA; Chief Editor: Dr Amanda Oakley, Dermatologist, Hamilton, New Zealand, January 2016.


Dentists and dental technicians are considered to be in a high-risk profession for occupational dermatoses. In one study out of Norway, for example, it was found that 40% of dentists suffer from job-related skin disorders, while a Belgian study found that 23% suffer from allergic contact dermatitis and 9% from chronic skin infections. An Australian study found that between 9% and 22% of those employed in dentistry suffer specifically from latex allergy.

Why are dentists and dental technicians at risk for skin problems?

Dentists and dental technicians are uniquely vulnerable to job-related skin problems.

Understanding the nature of occupational skin disorders

According to the United States Bureau of Labor Statistics, skin diseases are the most common form of occupation-related illness and represent around 16.5% of all work-related illnesses and injuries. These problems occur when various occupational hazards compromise the protective barrier of the skin and lead to irritation/inflammation, itch and pain.

Dentists and dental technicians are particularly prone to latex allergy and contact dermatitis.

Irritant contact dermatitis

Irritant contact dermatitis is often associated with “wet work”, or the constant or frequent submerging of hands in water. It can lead to acute dermatitis, ie redness, weeping or swelling, and on to chronic dermatitis, ie dry, cracked or scaling skin.

Latex allergy

Latex allergy is Type 1 hypersensitivity reaction to latex proteins (contact urticaria) and in extreme cases can rarely be fatal. Diagnosis based on medical history of immediate redness and swelling on exposure to the gloves. Latex reactions can be severe, but generally resolve within an hour or so.

Allergic contact dermatitis

Allergic contact dermatitis can arise from dental materials, solids, lubricating oils and X-ray chemicals. Specific allergens include:

Mechanical injury

Needle sticks and cuts/abrasians from sharps account for 50% of mechanical injuries in dentists and dental technicians. These are due to the small operating field, patient movement and the variety of sharps used. These injuries risk transmitting infection, including human immunodeficiency virus (HIV), hepatitis B and various bacteria.

Workplace risk assessment

Dental clinics and practices are highly regulated entities and this includes regulations for workplace risk. Agencies like the National Institute for Occupational Safety and Health (NIOSH) and similar regulatory bodies in other countries mandate employee education on infection control and prevention, sharps storage, use and disposal, safe handling of chemicals and cleaners used in dentistry and other aspects of workplace health.

Personal protective equipment

The use of gloves in mandated in the dental profession, mostly due to risk for transmission of viral illness, and to protect workers from exposure to potential irritants or allergens. However, many workers develop a sensitivity to latex or to other compounds in rubber gloves.

Increased use of non-latex gloves has led to a reduction in incidence of rubber allergy in dentists and dental technicians.
