[Periodontal ligament anaesthesia in tooth extraction].

The article deals with the application of periodontal ligament anesthesia (PA) in mandibular tooth extraction. The aim of the study was to examine the efficiency of PA; to assess the pain during the application of PA and tooth extraction; and to compare PA with mandibular anaesthesia using the same criteria for assessment. The frequency of PA was 66%. No significant differences were observed between the assessment of pain during PA and mandibular anaesthesia. However, about 96% of patients agreed with PA in next tooth extraction. There was no complication of PA during the study. Therefore, there is no substantial contraindication for PA in oral surgery.
