Actinic cheilitis (AC) is derived from the Greek word “cheilos,” meaning lips. AC
is a chronic, premalignant condition resulting from frequent and prolonged exposure
to sunlight, wherein the lower lip is most affected due to direct sunlight exposure.
The AC incidence is higher among Caucasian men than other ethnicities. It is estimated
that 17% of all AC cases can progress to carcinomas, and 95% of cancerous lips are
attributed to this lesion. Therefore, AC is significant in Brazil, a tropical country
that sustains its economy through activities where workers are continuously exposed
to solar radiation. Our literature review identified a need for training dentists
for AC diagnosis and prevention, mainly of professionals working in the basic public
health services in Brazil, through investments in continued education. AC can be simply
avoided; however, dentists must have adequate knowledge to prevent its occurrence
and progression. This study verified the importance of AC diagnosis — clinically or
by biopsy (obtained from hardened leukoplakic or ulcerated areas). Investing in continued
education of professionals and information for patients (to use lip balms) is of fundamental
importance for AC prevention and early diagnosis.
