Objectives: To evaluate the effect of 2% lignocaine containing 1:80,000 adrenaline on the microleakage and ultrastructure of resin tooth interface using an acetone based total etch adhesive (Prime and Bond NT) and an ethanol water based self etch adhesive system (Xeno III). Materials and method: Class V cavities were prepared on buccal surfaces of 72 maxillary first premolars scheduled for orthodontic extraction. In 36 premolars procedure was performed under local anaesthesia (LA) and in other 36 teeth without LA. Restorations were done with hybrid composite Spectrum TPH using either Prime and Bond NT or Xeno III bonding agents. Results: Administration of 2% lignocaine with 1:80,000 adrenaline significantly reduced microleakage and improved quality of hybrid layer and tubular penetration in Prime and Bond NT specimens; but no significant effect was observed in Xeno III specimens. Conclusion: Under clinical conditions, administration of LA reduced microleakage and improved quality of hybrid layer and tubular penetration in total etch adhesive systems.
