Teeth grinding: clenching or grinding your teeth puts an excessive force on the periodontium (teeth-supporting tissues), leading to the destruction of these tissues and the formation of periodontal pockets.

Apical Meristem Definition. The apical meristem is the growth region in plants found within the root tips and the tips of the new shoots and leaves. Apical meristem is one of three types of meristem, or tissue which can differentiate into different cell types. Meristem is the tissue in which growth occurs in plants. Apical is a description of growth occurring at the tips …

The apical pulse rate will never be lower than the peripheral pulse rate. The resulting number is the pulse deficit. Normally, the two numbers would be the same, resulting in a difference of zero.

The tip is cutting and pyramidal Helical angle: 45˚ Noncutting tips, also called Batt tips, are created by grinding and smoothing the apical end of the instrument 19. NiTi K-files are extremely flexible and are especially useful for apical enlargement in severe apical curves.

Grinding apical root segments of extracted teeth has been proposed to provide a more representative sample for a selective and more accurate analysis of the apical endodontic microbiota 14, 17, 18. For this analysis to be performed, extracted teeth or apical root fragments obtained by root-end resection have to be used.

Finally, the clinical crown was restored by a resin nanoceramic veneer made by a chairside system made up of an intraoral scanning unit and a grinding unit. Last, the authors carried through the endodontic surgery to extract the apical fractured fragment.

A clip for engaging tissue includes a generally annular-shaped body defining a plane and disposed about a central axis extending normal to the plane. The body includes alternating inner and outer curved regions, defining a zigzag pattern about a periphery of the clip. The body is biased towards a planar configuration lying in the plane and deflectable towards a transverse …

Extracted teeth with attached apical periodontitis lesions were sectioned so as to obtain two root fragments representing the apical third and the coronal two thirds. Root fragments were subjected to a cryogenic grinding approach.

order to get a fine powder using a grinding machine. Then the powdered sample (2g) was pressed into pellets by a 4 tons of hydraulic press. These pellets were used in EDX-700 spectrometer as specimens. ... These characters are the same in apical regions, central regions and basal regions but different in sizes.

Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which completely depends on their mining source. They are known as hydrous phyllosilicate having silica, alumina and water with variable amount of inorganic ions like …

Dry mouth: having a dry mouth can increase your risk of gum disease and dental caries. Dry mouth often occurs as a side effect of some ...

The blood-testis barrier (BTB) is one of the tightest blood-tissue barriers in the mammalian body. It divides the seminiferous epithelium of the seminiferous tubule, the functional unit of the testis, where spermatogenesis takes place, into the basal …

The periodontal ligament also allows the tooth to adapt to forces from tooth grinding (also known as bruxism) or other jaw clenching habits. The ligament can enlarge and allow the tooth to become loose. Once the excessive forces on the tooth are reduced, the PDL will heal, and tooth mobility will decrease.

Apical pulse is auscultated with a stethoscope over the chest where the heart's mitral valve is best heard. In infants and young children, the apical pulse is located at the fourth intercostal space at the left midclavicular line. In adults, the apical pulse is located at the fifth intercostal space at the left midclavicular line (OER #1).

Several prophylactic treatment methods are recommended for DE, such as selective grinding of the tubercles and application of resin to reinforce the tubercles. However, in the clinic, the fractured tubercle is frequently observed prior to complete root formation and leads to dental complications such as pulpal necrosis and apical periodontitis.

Thus, by grinding the yellow corollas as per the first step of traditional 'beni' manufacturing, PC converts to carthamin in the presence of CarS and aerial O 2, and the resulting carthamin is likely immediately absorbed by the cellulose matrices from the disrupted corolla cell walls. In this way, carthamin is retained in the matrices as a ...

Enamel — Enamel is the hard outer shell that covers the visible part (crown) of the tooth. It is able to withstand the stress of biting, chewing and grinding.

On the opposite (apical) surface, a Na + /glucose symport protein channel assists both Na + and glucose into the cell as Na + moves down the concentration gradient created by the basilar Na + ATPase pumps. The glucose molecule then diffuses across the basal membrane by facilitated diffusion into the interstitial space and from there into ...
