3. Which of the following diseases is a non -dental biofilm-induced gingival disease? a) Streptococcal gingivitis b) Drug-influenced gingival enlargement c) Puberty-associated gingivitis d) Pregnancy-associated gingivitis c) Menopause-associated gingivitis

The correct answer is a) Streptococcal gingivitis.<br /><br />Streptococcal gingivitis is a non-dental biofilm-induced gingival disease. It is caused by the accumulation of biofilm on the teeth and gums, which can lead to inflammation and infection of the gums. This condition is characterized by redness, swelling, and bleeding of the gums, and can be treated with good oral hygiene practices and, in some cases, antibiotics.
