まとめ
アルファカロチン (ビタミンAの前駆体) の濃度が高いと,米国の成人の根カリースのリスクが低くなります. この栄養素は,歯の根の表面の虫歯を防ぐ役割を果たすかもしれません.
科学分野:
- 口腔 衛生
- 栄養学
- 公衆衛生
背景:
- 虫歯は歯の根の表面に 影響を及ぼし 歯周病や口の乾燥 粘膜の健康に悪影響を及ぼします
- 特定のビタミンが口腔の健康,特に根カリアスに与える影響は まだ十分に研究されていない.
- アルファカロチン (α-カロチン) は強力な抗酸化物質であり,ビタミンAの代理であり,健康に潜在的な影響を及ぼします.
研究 の 目的:
- 血清アルファカロテンのレベルとアメリカ成人における根カリースの有病率との関連を調べる.
- アルファカロテンの潜在的保護作用を研究する.
- 口腔衛生戦略における栄養素の重要性を強調する.
主な方法:
- 2017~2018年の国家健康栄養調査 (NHANES) のデータを横断分析した.
- 関連性を評価するために重み付けされた複数のロジスティック回帰モデルを使用した.
- 年齢,性別,教育,人種,収入,歯周病などの 混同因子に調整されました.
主要な成果:
- 血清アルファカロチン濃度の上昇は,根カリースと逆に関連していた.
- 血清アルファカロテンの単位増加は,根カリースの確率は9%減少した (OR = 0. 91; 95% CI: 0. 86- 0. 97; p = 0. 004).
- 血清アルファカロテンの低下は,全国的に代表的な米国の成人のサンプルで,より高い根カリースの有病率に関連していた.
結論:
- 低血清アルファカロテンのレベルは,根の虫歯の有病率の増加と関連しています.
- アルファカロテンの栄養学的評価は 口腔の健康管理において有益である.
- アルファカロテンの口腔健康への影響を確認し解明するために,さらなる縦断的およびメカニズム的研究が必要である.

02:59Cancer Prevention
6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:21Tooth Anatomy
1.0K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

11.7K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

01:15Carbohydrates: Dietary Sources and Requirements
666
Carbohydrates are predominantly obtained from plant sources. With the exception of lactose found in milk and insignificant glycogen amounts in meat, most consumed carbohydrates have plant origins. Monosaccharides and disaccharides, or sugars, can be sourced from fruits, honey, milk, sugar cane, and sugar beets. Grains and vegetables are rich in the polysaccharide starch. Two types of polysaccharides provide fiber: cellulose, which is abundant in many vegetables, forms undigestible roughage or...

01:25Role of Vitamins in Maintaining Bone Health
3.6K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
