National Dental Assisting Examining Board (NDAEB) Practice Exam

Which of the following is NOT a recognized risk of smokeless tobacco?

1. Predisposition to leukoplakia

2. Higher incidence of gum disease

3. Immediate oral healing benefits

4. Increased risk of cancers in the throat

The correct answer is: Immediate oral healing benefits

The correct answer indicates that "immediate oral healing benefits" are not recognized risks associated with smokeless tobacco use. In fact, smokeless tobacco is known to have a variety of harmful effects on oral health rather than beneficial ones. For instance, smokeless tobacco can lead to leukoplakia, which is a condition characterized by white patches in the mouth that can predispose individuals to oral cancers. Additionally, it contributes to gum disease through the irritation and damage of periodontal tissues, increasing the likelihood of periodontal infections and tooth loss. Furthermore, the use of smokeless tobacco is also strongly linked to an increased risk of various types of cancers, including cancers of the throat, because the chemicals found in these products are carcinogenic and can affect the tissues in those areas. Thus, the idea that smokeless tobacco could provide "immediate oral healing benefits" contradicts the well-documented negative health impacts, solidifying this answer as appropriate in the context of recognized health risks associated with smokeless tobacco use.
