The underside of the carrier (10) is arranged a positioning portion so that the carrier (10) having mechanically conducting structure can be positioned on the cortical bone of the jawbone of the human body.陳烈堂陳貞竹
The tooth roots are protected by gums. But if the enamel is worn down or if the gum line has receded, then the dentin becomes exposed. "Cavities, cracked teeth, gum recession, the enamel, and root erosion all cause dentin to be exposed," Culotta-Norton said. 1 Share Anika Nicole, W...
Cavities may then form through weakened enamel and exposed dentine, and your teeth may even chip or crack. Cavities can also occur if the root of your tooth has been exposed due to receding gums, or if you have dry mouth, a condition in which you have less acid-neutralising saliva ...
whereby on the root is cementum and on the crown is enamel. Dentine is a part of your teeth that consists of many microscopic tubules of nerve endings. Therefore, if the dentin layer is not covered by an outer layer, the nerves are exposed to cold, hot, sweet,...
Receded gums are very common and up to four fifths of people have gum recession by the time they are 65. When the root of a tooth becomes exposed it does not have a layer of enamel like the crowns of your teeth. Instead the roots have a very soft covering called cementum, which ...

a neck covered by gum, and a crown, the exposed portion. In the center, pulp cavity is filled with a connective tissue reticulum containing a jellylike substance (dental pulp) and blood vessels and nerves that enter through one or more apertures at the apex of the root. The 20 deciduous...
(or shape). Specially curved probes are used to seek out, and by gentle probing, examine the contours of furcations exposed by bone loss. The clinician has to probe vertically beneath detached gum (like rappelling down the outside of a cave) and then feel for a furcation invasion by ...
exposed on the worn toothsurface. A further adaptation that occurs in horses and cattle involves elongation of the crowns until they extend nearly the full height of the jaws, with root formation delayed until maturity. These long-crowned (hypsodont) teeth continue to erupt until all the ...
Static magnetic field (SMF) promoting bone tissue remodeling is a potential non-invasive therapy technique to accelerate orthodontic tooth movement (OTM). The periodontal ligament stem cells (PDLSCs), which are mechanosensitive cells, are essential for f
