Which of the following is a subcategory of dental biofilm-induced gingivitis in the 2017 classification?

The correct answer is drug-influenced gingival enlargement, which is recognized as a distinct subcategory in the classification of gingival diseases. The 2017 classification system highlights this condition as it specifically occurs due to an adverse reaction to certain medications, such as anticonvulsants, calcium channel blockers, and immunosuppressants. This condition can lead to an increase in gingival tissue volume, which is important for clinicians to differentiate from other forms of gingival disease.

In contrast, plaque-induced gingival disease is a broader category that encompasses various forms of gingivitis primarily triggered by the accumulation of dental biofilm, without the specific association with medications. Hormonal gingivitis refers to gingival changes related to hormonal fluctuations, often seen during puberty or pregnancy, but it does not fall under the subcategory of drug-induced conditions. Viral-induced gingivitis is not a recognized subcategory in the current classification, as most classifications focus on plaque-induced processes and their modifications rather than viral infections. Thus, the acknowledgment of drug-influenced gingival enlargement in the classification emphasizes the importance of recognizing and managing medication-related gingival conditions effectively.
