During normal use, what is the most likely hazard for a dentist using a curing light?

1. Electric Shock

2. Heat Burns

3. Eye exposure to the light

4. Inhalation of fumes

The correct answer is: Eye exposure to the light

It is important for dentists to protect their eyes when using a curing light as the intense light can cause damage to the retina. This is the most likely hazard during normal use as dentists typically use protective gear to prevent electric shock and heat burns, and fumes are not typically produced during the process. While electric shock, heat burns, and inhalation of fumes can still be potential hazards, they are less likely to occur compared to eye exposure to the light. Therefore, the most likely hazard for a dentist using a curing light is eye exposure to the light.
