Root Canal Procedure
There are five steps in the root canal procedure.
Step 1: Before the root canal procedure, the dentist takes x-rays of the patient to understand the location of the pulp chamber and the number and shape of root canals.
Step 2: The dentist uses an electric drill device to drill open the tooth and remove the pulp and decay from the pulp chamber.
Step 3: The dentist uses a root canal length measurement device to determine the length of the root canal based on the x-ray data.
Step 4: The dentist fills the pulp cavity with a root canal filling. The root canal filling will replace the pulp and fill the space left after the pulp has been removed.
Step 5: The dentist uses a filling material to fill the tooth. After a few weeks, the dentist designs a crown for the patient and places the crown on the tooth.
Why root canal filling steps are important
A root canal filling is the last and most important step in root canal therapy. The dentist seals the root canal system tightly in three dimensions so that bacteria cannot re-enter the pulp cavity. The tooth is no longer attacked by bacteria so that it can be better preserved.
Difficulties with Root Canal Fillings
The root canal varies widely
Most root canal systems are not a simple straight root canal, but are as complex as the roots of a thousand-year-old tree. Root canals come in various shapes and degrees of bending. Complex apical branches and lateral collateral root canals. The above is a major problem for dentists.
The root canal must be moist.
The walls of the root canal must be clean and dry for the sealant to adapt well to them. The interior of the root canal is a moist place. Inflammation of the patient’s teeth increases the secretion of secretions, leaving the inside of the root canal in a non-dry state.
The filling material is not perfect
For more than 100 years, people have been searching for materials that tightly seal the root canal system. Currently, root canal filling materials are mainly glues, supplemented by sealants. However, neither of these materials can be perfectly adapted to the tooth. Therefore, the medical community continues to search.
