dentin的基础释义为：牙本质。发音为[?dentin]。英语范文如下：
Dentin is the main substance of teeth, which makes up about 80% of the mass of a tooth. It is a highly mineralized tissue and provides teeth with their hardness and strength. Dentin is composed of dead cells and inorganic material such as hydroxyapatite, which helps to give teeth their unique structure and function.
音标为：[d??t?n?n]
基础释义为：dentine teeth本质，牙本质，是构成牙齿的主要物质，占牙总重量的80%左右，是牙体组织的主要部分，是硬组织中较软的一种。它是一种高度矿化的组织，赋予牙齿其硬度和强度。牙本质由死细胞和无机物组成，如羟基磷灰石，这有助于牙齿具有其独特的结构和功能。
Dentin: The Secret Ingredient of Teeth
Dentin is a crucial component of teeth, playing a vital role in chewing and grinding food. It is a highly specialized tissue that is highly vascular, tough, and strong.
When we think of teeth, we often focus on the visible crown, but the root of the tooth is just as important. Dentin forms the foundation of the tooth, providing stability and support. It also acts as a shock absorber, absorbing impact and reducing the wear and tear on the rest of the tooth.
Dentin is unique in that it contains a high concentration of dentin matrix protein, which plays a role in tissue repair and regeneration. When teeth are damaged, this protein helps to heal the damage and restore the structure and function of the tooth.
However, dentin is not only essential for the structural support of teeth, but also plays a role in taste perception. Dentin contains sensory nerve endings that are sensitive to taste, allowing us to taste different flavors more keenly.
In conclusion, dentin is an essential component of teeth that plays a crucial role in chewing, grinding, structural support, and taste perception. Understanding its importance will help us to better care for our teeth and maintain their health and function.
Dentin (n.) is a tough, elastic tissue found in the roots of teeth and in the bones of some animals. It is a highly specialized tissue that provides support and protection for the teeth and bones.
Tooth decay is often caused by bacteria that feed on the soft tissue of the teeth, but dentin is protected by a hard outer layer called enamel. When this layer is damaged, bacteria can enter and cause infection and pain.
Dentin is also important for the growth and development of teeth. It provides nutrients and structure for the teeth to grow properly. Without dentin, teeth may not develop properly and may become weak and prone to decay.
In some cases, dentin can be damaged or lost due to disease or injury. This can result in pain, infection, and loss of function for the teeth. If this occurs, treatment may include restorative procedures such as filling or crowns to restore the lost structure and protect the remaining tissue.
In summary, dentin is a crucial tissue that provides support, protection, and nutrition for teeth and bones. Understanding its role in oral health is essential for maintaining good oral health and preventing disease.
