Answer: 2. Leukaemic
Explanation:
Conditional gingival enlargement (also known as inflammatory gingival enlargement) is caused by local irritants (like dental plaque) and is modified by systemic conditions. It is associated with hormonal changes (e.g., during pregnancy or puberty), certain medications (drug-induced), and is the underlying cause of lesions like granuloma pyogenicum.
Leukaemic gingival enlargement, however, is a non-inflammatory enlargement caused by the infiltration of leukaemic cells into the gingival tissues, which is a direct manifestation of systemic disease rather than a condition modifying a pre-existing inflammatory response.
