Assessment of pain after injection inside the tooth with different size needles during root canal treatment

Phase 3

Recruiting

• Conditions: patients requiring root canal treatment in lower molars with symptomatic irreversible pulpitis

• Registration Number: CTRI/2018/08/015227
• Lead Sponsor: Dr N Velmurugan

Brief Summary

The intrapulpal injection technique is commonly preferred in situations where patients encounter pain or discomfort during pulp extirpation. The main drawback with this technique is that the intrapulpal injection by itself can be highly painful . Various techniques have been tried to reduce the pain during intrapulpal anesthesia with the use of topical anesthesia prior to injection . However, the effect of needle gauge in reducing pain during intrapulpal injection remains unclear.

**Null Hypothesis** **–** states that the needle gauge does not influence the pain on injection and anesthetic efficacy of intrapulpal anesthesia. **AIM**- To evaluate pain on injection and anesthetic efficacy of intrapulpal anesthesia administered using different needle gauges (27 or 31gauge) with or without topical anesthesia
