We use both traditional methods of anaesthesia and a computerised anaesthetic system (QuickSleeper) which enables infiltration, intraligamentary, conduction and intra-osseous anaesthesia. A single injection in the oral vestibule area means: immediate anaesthesia of 2 to 6 teeth depending on the exact place of injection and the dose of the analgetic no anaesthesia of soft tissue (no tongue numbness effect) immediate anaesthesia of teeth with acute and chronic pulpitis no painful palate or tongue injections
