The aim of this study was to investigate the amount of damage to the lingual nerve by mandibular block anaesthesia alone. For this purpose the records of 12,104 patients in whom mandibular block anaesthesia was administered without any type of surgery were reviewed. The reason for treatment in those patients was, in 72.4% fillings and crown preparations, in 27.13% periodontal procedures and in 0.30% other treatment. The records showed a lingual sensory disturbance in 18 out of 12,104 patients (0.15%). In 17 out of these 18 patients the tongue sensation recovered after a period of 6 months. Only in one patient (0.008%) was there a slight sensory diminution of the tongue, even after one year.
