If a patient presents with red, swollen gingiva, moderate plaque biofilm, and probing depths of 2 to 3 mm, how should her disease status be classified?

The classification of the patient's disease status as dental biofilm-induced gingivitis is appropriate due to the presence of red, swollen gingiva, which indicates inflammation typically associated with gingivitis. The moderate plaque biofilm observed corroborates this diagnosis, as gingivitis is primarily triggered by the accumulation of dental biofilm on the teeth and gingiva.

Probing depths of 2 to 3 mm fall within the normal range for healthy gingival tissue, suggesting that there hasn't been significant attachment loss, which is a hallmark of periodontitis. In contrast, chronic periodontitis would typically present with deeper probing depths, clinical attachment loss, and possibly more advanced tissue damage.

The options related to gingival recession and necrotizing gingival disease do not apply here as there is no evidence of tissue destruction or recession mentioned in the patient's condition. Necrotizing gingival disease would be characterized by more severe clinical features and a distinct clinical presentation, such as ulceration or tissue necrosis, which is absent in this scenario.

Overall, based on the clinical signs presented, dental biofilm-induced gingivitis aptly describes the patient's condition.
