Neoplasms are a subcategory of which condition in the 2017 classification?

Neoplasms, which are abnormal growths of tissue that can be benign or malignant, are classified under nondental biofilm-induced gingival diseases according to the 2017 classification system for periodontal diseases and conditions. This classification recognizes that while most gingival diseases are influenced by dental biofilm (plaque), there are specific conditions, such as neoplasms, that arise independently of biofilm activity.

By placing neoplasms in the category of nondental biofilm-induced gingival diseases, it highlights that these growths can occur due to various factors other than the presence of plaque, such as systemic diseases, genetic factors, or environmental influences. This categorization helps clinicians to differentiate between typical inflammatory conditions caused by plaque and those resulting from other pathological processes, allowing for appropriate management and treatment strategies.

The other options refer to gingival issues tied to biofilm presence or to developmental conditions that do not encompass neoplastic growths. Nondental biofilm-induced gingival diseases specifically address the unique nature of such growths, which do not fit the classic definitions of periodontal diseases that are primarily inflammatory and biofilm-related.
