Precaine® (8% Lidocaine +0.8 Dibucaine) and Precaine®B(20% benzocaine) in children before local anesthetic injections. Study design- This is double blind clinical study included forty children divided equally under two techniques- palatal injections, inferior alveolar nerve block. Both the product were used alternatively with split mouth design in two visits and child’s pain response was assessed after local anesthetic injection using Wong baker scale and Taddoi’s modified behavioural pain scale. The scores obtained were subjected to statistical analysis. Result- Precaine® has shown lower mean score compare to Precaine® B for both the technique and pain scale. Gender wise comparison was not significant between Precaine® and Precaine® B.
