Filling is a conservative therapy, which aims at the reconstruction of coronal and radical tooth destruction that has been caused by cavity and external injury. As a result of developements in technology aesthetic fillings are more frequently used than the outmoded amalgam fillings.
Aesthetic filling: as its name shows with the use of it we can reach perfect cosmetic results. Aestehetic filling substances are uttered in different tinctures. The dentist can sort out the adequate colour with the help of different colour ranges.
The in-lay is a transition between filling and prosthesis. Dentists use it in case of destruction/lack which cannot be repaired safely with a filling. Its substance can be porcelain or composite affirmed with fiberglass. After the building of the cave and taking an imprint the dental technician makes the realistic reproduction of the missing part, what the dentist will fix with cementation.
On-lay will be made when chewing surface of the tooth has been destroyed. Its substance is porcelain and it is created the same way as in-lay.
Root canal treatment (RCT) is one of most frequently used interventions in odontology because the cavity is commonly located near the dental pulp. In line with spreading of cavity towards deeper layers symptoms become more characteristic. Initially mild sensitivity can be observed. This time processes in the tooth are reversible, the treatment of the tooth can be a simple filling. During the exacerbation of a cavity constant spontaneus pain can occur which indicates that the cavity has reached dental pulp, causing imflammation. In this case root canal treatment is inevitable. It involves the removal of nerves, the cleanup and filling of ducts. In some cases we can observe necrosis of dental pulp without imflammation (e.g. accident) and in its therapy root canal treatment plays an important role. If pulpitis enters through radical apex and spreads to the fixing apparatus of tooth then it can cause periodontitis and later bone substance destruction. In treating overreach radical apex both palliative and surgical interventions can become necessary.
