まとめ
オーストラリアの成人の間では 歯の脱落の社会的不平等が続いている. 低所得層は,歯の脱落や非機能歯の減少が 顕著である. 年齢,性別,歯医者への定期訪問などの要因が 歯の脱落に影響します
科学分野:
- 公衆衛生
- 流行病学
- 歯科公衆衛生
背景:
- 歯の脱落の社会的不平等は 深刻な公衆衛生問題です
- 歯の脱落の傾向を理解することは 対象を絞った介入に不可欠です
研究 の 目的:
- 時間の経過とともにオーストラリアの成人の間で歯の喪失の社会的差異を記述し,調査する.
- エデントリズムと非機能性歯の流行の変化を 収入グループで評価する.
主な方法:
- 2004~2006年と2017~2018年に実施された全国成人口腔健康調査 (NSAOH) のデータを活用した.
- 15歳以上の成人を対象に,人口ベースの横断設計を採用した.
- 家庭の収入,社会人口統計,口腔衛生に関する行動に関連して評価されたエデントリズムと非機能的な歯 (<21本の歯)
主要な成果:
- エデントル症の罹患率は6. 4%から4. 0%に減少し,非機能歯の罹患率は17. 1%から13. 8%に減少した.
- すべての所得四分位で減少が観察され,最も低い所得グループで最も顕著な減少が観察されました.
- 調整されたモデルでは,最も低い所得の四分位において,エデントリズム (PD=8. 8),非機能歯 (PD=13. 7) の有意な減少を示した.
結論:
- エデントリズムや非機能的な歯の社会的不平等はオーストラリアの成人の間で続いている.
- 年齢,性別,居住地,不定期の歯科診察,歯科保険の欠乏 など が 歯 の 失れ に 関する 重要な 要因 です.

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...

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...

01:29Bone Disorders
3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:26Assessment of the Mouth
404
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

02:20Longitudinal Research
12.5K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:19The Effect of Aging on Tissues
2.4K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
