What is Root Canal Treatment (Endodontics)?<\/strong><\/span><\/h4>
Contrary to common belief, root canal treatment is not for \u201ckilling\u201d a tooth, but for \u201csaving\u201d it. When decay passes through the enamel and dentin and reaches the pulp (the soft tissue containing nerves and blood vessels), the tooth develops severe inflammation and infection. At this stage, root canal treatment is the only way to preserve the tooth root in the mouth and prevent its extraction. Root canal treatment or endodontic therapy is one of the specialized treatments in dentistry that is performed to save a tooth whose pulp (the soft tissue inside the tooth) has become inflamed or infected. This treatment helps preserve the natural tooth and prevents its extraction.<\/span><\/h5>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Precise Steps of Root Canal Treatment<\/strong><\/span><\/h4>
In order for the root canal treatment (Endodontics) section on Dr. Hessam Nazari<\/strong><\/span>\u2019s website to be completely professional and trustworthy, the steps should be explained in a way that carries scientific value while also reducing the patient\u2019s fear of this procedure (which is usually associated with anxiety).<\/span><\/h5>
Here are the precise and specialized steps of root canal treatment presented step by step:<\/span><\/h5>
1.Specialist Examination and Radiographic Imaging (Radiographic Exam)<\/strong><\/span><\/h5>
The first step is the precise evaluation of the roots. Using digital radiographs (RVG), the dentist examines the number of canals, the degree of root curvature, and the extent of infection in the apex area (the end of the root) in order to design the most accurate treatment plan.<\/span><\/h5>
2.Complete Anesthesia and Pain Elimination (Deep Anesthesia)<\/strong><\/span><\/h5>
Contrary to common belief, root canal treatment should not be painful. In our clinic, using modern local anesthesia techniques, the tooth and surrounding tissues are completely numbed so that the patient remains fully comfortable during the treatment.<\/span><\/h5>
3.Isolation with Rubber Dam (Isolation)<\/strong><\/span><\/h5>
This stage reflects the quality of the procedure. The tooth is isolated from the oral environment using a rubber sheet (Rubber Dam).<\/span><\/h5>
Goal:<\/strong> Prevent saliva (which contains bacteria) from entering the canals and protect the patient\u2019s throat from irrigating solutions.<\/span><\/h5>
4.Creating the Access Path (Access Cavity)<\/strong><\/span><\/h5>
The dentist removes superficial decay and creates an access path toward the center of the tooth (pulp) in order to reach the openings of the root canals.<\/span><\/h5>
5.Cleaning and Shaping the Canals (Cleaning & Shaping)<\/strong><\/span><\/h5>
At this stage, infected tissues, damaged blood vessels, and inflamed nerves are removed from inside the canals.<\/span><\/h5>
Rotary Technology<\/strong>: We use rotary files, which are very flexible and precise, to smooth and shape the canal walls so they are ready for filling.<\/span><\/h5>
6.Digital Working Length Determination (Working Length)<\/strong><\/span><\/h5>
Using an Apex Locator device, the exact length of each canal up to the end of the root is measured with tenth\u2011of\u2011a\u2011millimeter precision to ensure that no infected area remains.<\/span><\/h5>
7.Chemical Irrigation and Disinfection (Disinfection)<\/strong><\/span><\/h5>
Physical cleaning alone is not sufficient. The canals are irrigated with special solutions (such as sodium hypochlorite) to eliminate bacteria hidden in the microscopic pores of the root walls.<\/span><\/h5>
8.Filling the Canals (Obturation)<\/strong><\/span><\/h5>
After the canals are completely dry and sterile, they are sealed three\u2011dimensionally with a material called gutta\u2011percha (a plant\u2011based resin compatible with the body) and special sealers to permanently block any pathway for bacterial re\u2011entry.<\/span><\/h5>
9.Temporary Dressing or Final Restoration<\/strong><\/span><\/h5>
Since the tooth becomes weaker and more fragile after root canal treatment, the dentist depending on the situation either places a temporary dressing or prepares the tooth directly for final restoration (post, composite, or crown).<\/span><\/h5>
Golden Tip for Patients<\/strong>: Root canal treatment is only half the journey; a tooth that has undergone root canal treatment no longer has blood supply and becomes fragile like a dry branch. After completing the treatment, be sure to consult your dentist about placing a crown or a strong composite restoration to prevent sudden tooth fracture.<\/span><\/h5>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
