Introduction
Root extraction generally refers to the removal of residual tooth roots remaining in the jawbone after the crown has been destroyed. The most common causes include dental caries and complete crown destruction, or fractured roots left behind during previous extractions. Larger roots or those retained for prolonged periods may lead to chronic inflammation in the surrounding tissues, necessitating prompt removal.
Root extraction generally refers to the removal of residual dental roots remaining in the jawbone after the crown has been destroyed. The most common causes include dental caries, complete crown destruction due to corrosion, or fractured root fragments inadvertently left behind during prior tooth extractions. The procedure proceeds as follows:
1. Anesthesia: The patient lies supine on the dental chair. After routine disinfection and draping, local anesthesia is administered using lidocaine.
2. Extraction: Once anesthesia has taken effect, an elevator is used to loosen the root(s). If multiple roots are present, each may be individually loosened before extraction using root forceps.
3. Debridement: After all roots have been removed, the alveolar socket is curetted to eliminate inflamed granulation tissue.
4. Hemostasis: Finally, a sterile cotton pellet is placed into the extraction site to achieve hemostasis.
Typically, the hemostatic cotton pellet may be removed after 30 minutes. Following root extraction, patients should maintain a bland diet, avoid smoking and alcohol, and practice good oral hygiene. Generally, roots smaller than 3 mm in size and asymptomatic may be left untreated.
