What is Endodontics?
Endodontics is a branch of dentistry that deals with the internal structure of the tooth (pulp). The pulp is the soft tissue located in the center of the tooth and contains nerves, blood vessels, and connective tissues. Endodontics provides diagnosis, treatment, and protection, especially when the pulp is inflamed, infected, or damaged. The most common endodontic treatment is root canal treatment.
Root Canal Treatment: It is the process of cleaning, shaping, and filling the pulp tissue affected by decay and bacteria with a filling material.
What Does Endodontic Treatment Aim For?
The main purpose of endodontics is to save the tooth from extraction and keep it in the mouth, increase the patient’s comfort by eliminating symptoms such as severe pain, protect the health of periapical tissues, ensure infection control, and allow the patient to continue chewing functions.
Main Goals
- To Relieve Pain: To relieve severe toothache caused by pulp inflammation (pulpitis) or infection.
- To Clear Infection: To prevent the spread of infection by cleaning the infected tissues and bacteria inside the root canal system.
- To Preserve Tooth Function: To keep the treated tooth in the mouth functionally and aesthetically by restoring it.
- To Maintain the Health of the Tooth for a Long Time: To make the tooth long-lasting by strengthening it with appropriate restorations.
Basic Concepts Related to Endodontics
- Pulpa: The living tissue located in the center of the tooth.
- Pulpitis: Inflammation of the pulp. Classified as reversible or irreversible.
- Periapical Lesion: Lesions caused by infection at the root tip, often appearing as abscesses.
- Apex: The tip of the tooth root.
- Apexification: A method used to close the root tip in immature teeth.
- Devitalization: Loss of vitality of the pulp.
- Obturation: The permanent filling of root canals.
- Retrograde Filling: Surgical filling done from the root tip.
Endodontic Treatment Methods
- Root Canal Treatment: The infected pulp is removed, canals are cleaned and shaped, then filled with a biocompatible material and restored.
- Retreatment: Renewal of a previously failed root canal treatment.
- Apexification and Apexogenesis: Use of materials like calcium hydroxide in immature teeth to aid root development.
- Apical Resection (Apicoectomy): Surgical removal of infected tissue at the root tip.
- Pulp Capping (Direct and Indirect): Special materials are used to protect the pulp in cases of exposure or near-exposure.
- Vital Pulp Therapy: Treatments to keep the pulp alive, especially in young patients.
- Root Canal Perforation Repair: Repair of accidental holes in the root with biocompatible materials.
Use of Microscope in Endodontics
The endodontic microscope magnifies the internal structure of the tooth, allowing better visibility and precision.
Advantages of Microscope Use
- Small cracks, extra canals, and perforations are easily identified.
- Accurate diagnosis in complex cases.
- More precise shaping and filling of canals.
- Micro fractures in the tooth root can be detected.
- Minimally invasive approach for surrounding healthy tissues.
Where It Is Used
- Detection of extra or narrow canals
- Repair of accidental perforations
- Retreatment of failed root canal procedures
- Identification of root fractures
- Apical surgery and retrograde fillings
Rubber-Dam Application
Rubber-dam is a rubber sheet used to isolate teeth during dental procedures. It provides excellent isolation, especially in root canal treatments and anterior aesthetic restorations.
Usage Areas
- Endodontic treatments
- Aesthetic restorations
- Teeth whitening
Advantages
- Keeps the working area dry and clean
- Prevents contamination from saliva
- Increases patient safety
- Shortens treatment time and improves success
