Nutrition et santé bucco-dentaire

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.

Nutrition is a science with two main axes: Physiology of nutrition, concerning food transformation by the organism, and Psychology of nutrition, analyzing eating behaviors.

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.

A diet high in saccharose facilitates microbial development by providing the inter-microbial matrix, leading to significant periodontal problems.

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.

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.

Calcium deficiency can lead to the destruction of the alveolar-dental ligament and affect the periodontal bone.

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.

Carbohydrates should provide 55% of daily energy intake. Their primary source for dental health recommendations is whole grains, although sugary foods increase cavity risk.

Lipids should constitute 25% to 30% of daily energy intake. Excess fats can cause cell agglutination, disrupting subgingival capillary circulation and impacting tissue metabolism.

Fluorine increases tooth resistance to decay. It plays a crucial role in mineralizing enamel, making teeth less susceptible to caries.

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.

Avoid snacking, consume calcium-rich foods, and eat fruits/vegetables rich in Vitamin C. Drink plenty of water and eat fiber-rich foods.

Vitamin D maintains the calcium-phosphorus balance. The calcium-phosphorus ratio is crucial for a healthy organism, and Vitamin D helps maintain this equilibrium.

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.

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.

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.

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.

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.
