Patient Background
A 28-year-old software engineer arrived at ORC with severe, throbbing pain in the lower right molar. The pain had been worsening for 3 days and was disrupting sleep and work. The patient was extremely anxious about dental treatment.
Initial Assessment
- Condition: Irreversible pulpitis with periapical involvement
- Tooth: #46 (lower right first molar)
- Symptoms: Spontaneous pain, sensitivity to hot/cold, pain on biting
- Radiograph: Deep caries approaching pulp, periapical radiolucency
- Patient Anxiety: High — first root canal experience
Treatment Planning
Given the acute symptoms and patient’s anxiety, we planned a single-sitting root canal treatment using:
- Computer-controlled local anesthesia for painless numbing
- Rotary endodontics (ProTaper Next) for efficient cleaning
- Apex locator for precise working length determination
- Warm vertical gutta-percha for 3D obturation
Treatment Process
Step 1: Anesthesia (10 minutes)
- Applied topical anesthetic gel before injection
- Administered inferior alveolar nerve block with buffered lidocaine
- Achieved complete numbness — patient reported zero pain during procedure
Step 2: Access & Cleaning (45 minutes)
- Created conservative access cavity preserving tooth structure
- Located all 3 canals (mesiobuccal, mesiolingual, distal)
- Shaped canals using ProTaper Next rotary files to size 25/0.08
- Irrigated with sodium hypochlorite (2.5%) and EDTA
- Dried canals with paper points
Step 3: Obturation (20 minutes)
- Filled canals using warm vertical gutta-percha technique
- Achieved dense 3D seal at all working lengths
- Verified with post-operative radiograph — perfect fill
Step 4: Restoration (15 minutes)
- Placed composite resin base for coronal seal
- Advised crown placement within 2 weeks for fracture prevention
Outcome
The patient experienced immediate pain relief and was amazed at how comfortable the procedure was:
- ✅ Zero pain during the entire 90-minute procedure
- ✅ Immediate relief from the acute toothache
- ✅ Same-day treatment — no multiple visits needed
- ✅ Anxiety eliminated — patient now comfortable with dental care
“I was terrified of root canals, but I didn’t feel a thing! The pain I had was gone immediately after the procedure. I can’t believe I waited so long.” — Patient testimonial
Key Takeaways
- Modern root canal treatment is completely painless with proper anesthesia
- Single-sitting RCT is safe and effective for most cases
- Rotary endodontics reduces treatment time significantly
- Early treatment saves the natural tooth and prevents extraction
