The MTA will provide structure and strength to the tooth by replacing the resorbed tooth structure. In external resorption, after root canal therapy is performed, the flap is raised over the tooth and the defect removed from the root surface with a round bur. Retrograde application of MTA to the root surface is then completed.
A systematic review concluded that for decayed baby (primary) teeth, putting an off‐the‐shelf metal crown over the tooth (Hall technique) or only partially removing decay (also referred to as "selective removal" [5]) before placing a filling may be better than the conventional treatment of removing all decay before filling.

Oral hygiene practices involve the mechanical removal of plaque from hard tissue surfaces [24] Cariogenic bacteria levels in the plaque determine whether caries will occur or not, therefore, effective removal of plaque is paramount. [25] The removal of plaque inhibits demineralisation of teeth, and increases opportunities for remineralization.
The M102 engine family is a inline-four gasoline automobile engine family built by Mercedes-Benz in the 1980s and early 1990s. It is a relatively oversquare engine with a large bore and short stroke compared to the M115 engine which was used during the same timeframe.
Although the structure proposed by Ziegler was not confirmed, he was able to develop an alternative synthesis of tartrazine based on the idea that a hydrazone is the tautomeric form of an azo compound (azo-hydrazo tautomerism). This production process was patented in 1893 (British Patent 5693). [7] [8]
Dental impressions are negative imprints of teeth and oral soft tissues from which a positive representation can be cast. They are used in prosthodontics (to make dentures), orthodontics, restorative dentistry, dental implantology and oral and maxillofacial surgery.

A dental dam or rubber dam is a thin, 6-inch (150 mm) square sheet, usually latex or nitrile, used in dentistry to isolate the operative site (one or more teeth) from the rest of the mouth. Sometimes termed " Kofferdam " (from German ), it was designed in the United States in 1864 by Sanford Christie Barnum [ de ] . [ 1 ]
