What does the term 'materia alba' refer to in dental hygiene?

• A. Food debris and bacterial colonies
• B. Soft, non-mineralized deposits on teeth
• C. A type of calculus
• D. A form of periodontal tissue

Answer: (B)

The term 'materia alba' refers specifically to soft, non-mineralized deposits that can accumulate on the surfaces of teeth. It is a whitish or pale yellow, gelatinous mass that consists of bacteria, desquamated epithelial cells, food particles, and other debris. Materia alba can contribute to oral hygiene issues as it can serve as a reservoir for bacteria, which, if not removed, can lead to plaque formation and subsequently dental caries or periodontal diseases. In the context of dental hygiene, understanding materia alba is crucial because it highlights the importance of regular oral hygiene practices, such as brushing and flossing, to minimize its accumulation and maintain overall oral health. It is distinct from other components related to oral health, such as calculus, which refers to mineralized plaque that has hardened on the teeth.
