Standard Operating Procedure: Routine Dental Extraction

This Standard Operating Procedure (SOP) outlines the clinical protocol for a routine dental extraction to ensure patient safety, minimize post-operative complications, and maintain aseptic standards. This document is intended for use by licensed dental professionals and clinical support staff. Adherence to these steps ensures consistency in care, optimal healing outcomes, and the mitigation of surgical risks such as nerve injury, alveolar osteitis, or fractured roots.

I. Pre-Operative Preparation

• Patient Verification: Confirm identity and reconcile the medical history (allergies, anticoagulants, bisphosphonates, cardiac conditions).
• Imaging: Review periapical or panoramic radiographs to assess root morphology, proximity to the sinus/nerve canal, and bone density.
• Informed Consent: Review the risks (dry socket, root fracture, sinus perforation, paresthesia) with the patient and obtain a signed consent form.
• Anesthesia: Administer local anesthetic appropriate for the site; confirm profound anesthesia via clinical testing before starting.
• Aseptic Field: Prepare the surgical tray with sterile instruments, ensuring the patient is draped and the clinical team is wearing appropriate Personal Protective Equipment (PPE).

II. Surgical Procedure

• Syndesmotomy: Use a periosteal elevator or a sharp blade to sever the epithelial attachment around the neck of the tooth.
• Luxation: Apply controlled force using an elevator to expand the alveolar bone and mobilize the tooth. Do not use adjacent teeth as a fulcrum.
• Extraction: Transition to forceps, ensuring a deep apical seat on the root surface. Use rotational, buccal, and lingual forces to move the tooth out of the socket.
• Debridement: Use a surgical curette to remove granulation tissue, debris, and fractured bone spicules from the extraction site.
• Hemostasis: Perform a final inspection of the socket. Place sterile gauze under firm pressure for 15–20 minutes to achieve initial clot formation.
• Suturing: If the socket is large or bleeding is persistent, place resorbable sutures to approximate the gingival margins.

III. Post-Operative Management

• Patient Education: Instruct the patient on pressure application (biting on gauze), avoiding straws, smoking, or vigorous rinsing for 24 hours.
• Medication: Review post-operative analgesia (NSAIDs/Acetaminophen) and any prescribed antibiotics.
• Documentation: Record the tooth number, anesthesia used, difficulty of extraction, post-op instructions provided, and any complications encountered.

Pro Tips & Pitfalls

• Pro Tip: If a tooth does not move, stop. Re-evaluate the radiographs or consider sectioning the tooth (if multi-rooted) rather than applying excessive force that could fracture the mandible or tuberosity.
• Pro Tip: Always palpate the buccal plate after extraction to ensure no sharp bony edges remain that could cause post-operative discomfort.
• Pitfall: Over-reliance on forceps early in the process. Forceps are for removal; elevators are for mobilization. If the tooth isn't mobile, the forcep application will likely result in crown fracture.
• Pitfall: Failure to document an "at-risk" medical history. Always ensure blood pressure is stable before beginning, especially in anxious patients.

Frequently Asked Questions (FAQ)

1. How long should the patient keep the gauze in place? The patient should maintain firm, constant pressure on the gauze for 30–60 minutes. If bleeding persists, they should replace it with fresh gauze for another 30 minutes.

2. What is the most common cause of a "dry socket"? The most common cause is the dislodgement or early dissolution of the blood clot. This is frequently linked to using straws, spitting vigorously, or smoking within the first 48 hours post-op.

3. When should a patient be advised to call the clinic? Patients should contact the clinic if they experience uncontrolled bleeding, fever, signs of infection (pus/foul taste), or if numbness persists significantly longer than the expected duration of the anesthetic.
