STUDY ON INFILTRATION LOCAL ANAESTHESIA FOR EXTRACTIONS IN THE POSTERIOR MANDIBLE
Objectives: To record the data from extractions in the posterior mandibular arches over 14 years.
Methods: Data was collected for each tooth that was extracted over fourteen years. Teeth extracted were mandibular molars and second premolars. Tooth extraction was performed in one dental practice by the same operator. Badly broken down teeth were extracted surgically. This involved flapless, bone sparing surgery with guttering with a tapered diamond bur and elevation using luxators. An intraligamentary local anaesthetic technique was used and achieved sufficient anaesthesia for extraction including surgicals. An intraligamentary syringe with a short needle was used at two points buccal and two points lingual. Demographic and qualitative and quantitative data were collected at the extractions and during the subsequent review appointment.
Results: 272 mandibular posterior teeth were extracted in subjects aged 59-61years. As part of a larger study all teeth were extracted using the intraligamentary technique and included 13% (n=119) second molars, 9% (n=79) first molars, 5% (n=46) second premolars and 3% (n=28) third molars. The average extractions performed per tooth using the intraligamentary technique was a median 27%, inter quartile range 18%-50%. The proportion of overall teeth extracted surgically over 6 years was 16% (n=43). All surgical extractions were performed using the intraligamentary local anaesthetic. The remainder of cases with intraligamentary anaesthesia were mostly for periodontitis (34%,n=92) and periapical infection.(29%, n=80).There was no increase in adverse events or post-operative symptoms reported by patients compared with conventional techniques.
Conclusions: Intraligamentary anaesthesia has been shown to be important to obtain sufficient anaesthesia for surgical extractions and extraction of teeth with irreversible pulpitis in particular the molar teeth. The length of anaesthesia was less than conventential anaesthetic techniques, due probably to the more ready dispersion of the local anaesthesia and there was no increase in post operative symptoms compared with convententional techniques.
