Standard Operating Procedure: Routine Dental Extraction

This Standard Operating Procedure (SOP) outlines the clinical protocol for a routine dental extraction. The objective is to ensure patient safety, minimize post-operative complications, and maintain strict adherence to aseptic techniques. This document is intended for use by licensed dental professionals and clinical support staff. All procedures must be performed in accordance with the clinic’s infection control policies and the patient’s current medical history.

Phase 1: Pre-Operative Preparation

• Medical History Review: Confirm no contraindications (e.g., current anticoagulation therapy, bisphosphonate use, or uncontrolled systemic conditions).
• Radiographic Evaluation: Review high-quality periapical or panoramic radiographs to assess root morphology, proximity to the mandibular canal/sinus, and surrounding bone density.
• Informed Consent: Ensure the patient understands the risks (dry socket, nerve paresthesia, root fracture, sinus involvement) and the procedure has been signed off.
• Time-Out Procedure: Verify patient identity, the specific tooth number, and the correct side before administering anesthetic.
• Equipment Setup: Prepare extraction kit (periosteal elevator, elevators, forceps) and sterile gauze.

Phase 2: Anesthesia and Preparation

• Local Anesthesia: Administer appropriate block or infiltration. Wait for objective signs of anesthesia (numbness, loss of proprioception) before proceeding.
• Sulcular Incision: Use a sterile blade to sever the epithelial attachment around the tooth to prevent mucosal tearing during luxation.
• Syndesmotic Separation: Utilize a periosteal elevator to reflect the gingival tissue slightly and sever the periodontal ligament (PDL) fibers.

Phase 3: Extraction Procedure

• Luxation: Employ elevators (e.g., straight elevator, Luxators) to expand the alveolar bone and sever PDL fibers. Apply controlled force to loosen the tooth from the socket.
• Forceps Application: Seat the forceps blades as apically as possible on the root surface. Apply firm, controlled pressure.
• Extraction Force: Utilize the path of least resistance (usually buccal for maxillary teeth; distal/lingual for mandibular teeth). Use a slow, rhythmic movement to expand the socket.
• Delivery: Remove the tooth from the socket using a controlled rotational or rocking motion.

Phase 4: Post-Extraction Care

• Debridement: Use a surgical curette to remove any granulomatous tissue, debris, or bone fragments from the socket.
• Hemostasis: Apply firm pressure with sterile gauze for 5–10 minutes. If a clot does not form, utilize a collagen plug or suture if necessary.
• Post-Op Instructions: Provide written instructions emphasizing avoidance of straws, smoking, and vigorous rinsing for 24–48 hours.
• Documentation: Record the extraction outcome, any fractured root tips remaining, and the patient's immediate response in the clinical notes.

Pro Tips & Pitfalls

• Pro Tip: If the tooth is not moving after initial luxation, do not increase force. Re-evaluate the tooth position and perform deeper PDL separation. Excess force leads to bone fracture.
• Pro Tip: Always palpate the buccal plate after extraction to ensure no sharp bone spicules remain, which could cause post-op pain or interfere with healing.
• Pitfall: Ignoring the "forceps-first" trap. Never use forceps as an elevator. If you do not have good purchase or the tooth is not luxated, stop and use an elevator again.
• Pitfall: Failure to account for curved or dilacerated roots visible on the radiograph. Always plan for potential root tip fracture in these cases.

FAQ

Q: How long should a patient keep the gauze in place? A: Firm, constant pressure should be maintained for 30–60 minutes. If bleeding persists, replace the gauze with a fresh piece and apply pressure for another 30 minutes.

Q: What should the patient do if they experience a "dry socket"? A: If the patient experiences increasing pain 3–5 days post-extraction (often accompanied by an exposed bone or foul taste), they should contact the office immediately for a socket dressing placement (e.g., Alvogyl).

Q: Is it normal to have swelling after the procedure? A: Yes, mild swelling is a normal inflammatory response. Advise the patient to use an ice pack for the first 24 hours (20 minutes on, 20 minutes off) to minimize edema.
