AS THE SOLUTION TO ROOT PROBLEMS
When caries attacks in-depth the dental pulp, called nerve in common parlance, it is necessary to perform an endodontic or root canal treatment (devitalization) that removes tissue from both the crown and the roots.
Endodontic therapies are therefore fundamental because they allow the rehabilitation of teeth that would otherwise be extracted.
After local anaesthesia, the removal of tissue is performed along with the careful shaping of root canals, which are attentively cleaned with special irrigants performing a powerful antibacterial action.
Indeed, only a clean and well disinfected root canal can receive a filling with good long-term success rates.
The tissue removed the from root canals is then replaced with thermoplastic filling (i.e. heat-mouldable) materials and cements which serve as an adhesive between the tooth and the material used for the filling.
The joint use of thermoplastic material and cement completely and tridimensionally fills in the root canals so as to seal all residual spaces and eliminating the presence of hollows that might later be colonised by bacteria. To verify the completeness of the filling, which should reach the root apex, radiological check is also carried out.
Finally, the final restoration of the tooth is either performed with a direct reconstruction, which is similar to a normal filling, or with an indirect reconstruction if the tooth needs a prosthetic cover (inlay, metal-ceramic crown, integral ceramic crown and the like).
It is important to stress that, thanks to local anaesthesia, the patient will not feel the slightest pain throughout the therapy. A slight soreness, which will however be of short duration, may be experienced at a later stage.
