Question
How does vitamin A deficiency affect dental enamel and the periodontal tissues?
Answer
Vitamin A deficiency affects dental enamel by causing poor mineralization and can lead to leukoplakic states in the periodontal tissues. It impacts epithelial derivatives, including the enamel and oral mucosa.
Question
Which vitamin maintains the calcium-phosphorus balance in the body?
Answer
Vitamin D maintains the calcium-phosphorus balance. The calcium-phosphorus ratio is crucial for a healthy organism, and Vitamin D helps maintain this equilibrium.
Question
What is the phospho-calcic ratio and why is it important for oral health?
Answer
The phospho-calcic ratio refers to the balance between calcium and phosphorus, crucial for healthy bone and tooth mineralization. This ratio, maintained by Vitamin D, is vital for preventing periodontal destruction and maintaining tooth structure, contributing to overall oral health.
Question
What are the periodontal consequences of protein deficiency?
Answer
Protein deficiency can lead to osteoporotic bone tissue, less dense collagen, a thinned and possibly ulcerated epithelium, and depressed immune mechanisms, increasing susceptibility to infection.
Question
What are the three main dietary recommendations for adults to maintain good oral health?
Answer
Avoid snacking, consume calcium-rich foods, and eat fruits/vegetables rich in Vitamin C. Drink plenty of water and eat fiber-rich foods.
Question
What is the role of fluorine in preventing dental caries?
Answer
Fluorine increases tooth resistance to decay. It plays a crucial role in mineralizing enamel, making teeth less susceptible to caries.
Question
Why is sugar the primary cause of dental caries, and how does frequency of consumption matter?
Answer
Sugar is the primary cause of dental caries because it feeds oral bacteria, which produce acids that erode tooth enamel. The frequency of consumption matters; more frequent sugar intake leads to prolonged acid exposure, increasing decay risk. Limiting sugar and frequent snacking is crucial for dental health.
Question
What are the oral manifestations of vitamin C deficiency (scurvy)?
Answer
Vitamin C deficiency (scurvy) causes stomatitis scorbutica, vivid red gingivitis, spontaneous hemorrhages, ulcerations, and affects the supporting structures of teeth, potentially leading to tooth loss.
Question
What are the periodontal consequences of calcium deficiency?
Answer
Calcium deficiency can lead to the destruction of the alveolar-dental ligament and affect the periodontal bone.
Question
How does a high-saccharose diet affect the development of periodontal problems?
Answer
A diet high in saccharose facilitates microbial development by providing the inter-microbial matrix, leading to significant periodontal problems.
Question
What is the etymology of the word 'nutrition' and what does it mean?
Answer
The word nutrition comes from the Latin word nutrire, meaning "to nourish." It refers to the processes by which a living organism transforms food to sustain its functions. It encompasses both the physiological transformation of food and the behavioral aspects of eating.
Question
What does vitamin D deficiency cause in dental development?
Answer
Vitamin D deficiency can cause delayed dental development, malformation of the maxillaries, and potentially contribute to a hollow enamel due to its role in calcium and phosphorus metabolism.
Question
Define oral health and list its primary functions.
Answer
Oral health encompasses the condition and function of the mouth, particularly teeth and gums. Its functions include eating, speaking, laughing, and fighting infections like tooth decay and gum inflammation, which can lead to tooth loss and bad breath.
Question
What percentage of daily energy intake should lipids constitute, and how do excess fats affect subgingival circulation?
Answer
Lipids should constitute 25% to 30% of daily energy intake. Excess fats can cause cell agglutination, disrupting subgingival capillary circulation and impacting tissue metabolism.
Question
Explain the two main axes of nutrition as a scientific discipline.
Answer
Nutrition is a science with two main axes: Physiology of nutrition, concerning food transformation by the organism, and Psychology of nutrition, analyzing eating behaviors.
Question
What is the recommended daily protein intake for a 12-year-old child?
Answer
A daily intake of 100g of protein is recommended for individuals aged 12 and older.
Question
How do balanced and unbalanced diets affect periodontal health?
Answer
A balanced diet supports healthy teeth and gums, aids recovery, and strengthens the immune system. An unbalanced diet, especially high in sugars and low in fiber, can lead to gum problems, increased caries, and a weakened immune response, amplifying local irritants and disease progression.
Question
What is the direct relationship between nutrition and dental health?
Answer
Nutrition directly impacts dental health; vitamins and minerals strengthen or weaken teeth and gums. A healthy immune system, crucial for combating infections, relies on good nutrition. Deficiencies can lead to issues like cavities, gum inflammation, and slower healing.
Question
What percentage of daily energy intake should come from carbohydrates, and what is their primary source?
Answer
Carbohydrates should provide 55% of daily energy intake. Their primary source for dental health recommendations is whole grains, although sugary foods increase cavity risk.
Question
Name two roles that diet plays in the etiology of dental caries.
Answer
Diet affects tooth tissue development and conservation. It also influences dental plaque and saliva production based on food properties, composition, and eating habits, especially with frequent sugary snacks.
