TO COMPARE THE EFFECTIVENESS OF INTRALIGAMENTARY INJECTION ANAESTHESIA VERSUS INFERIOR ALVEOLAR NERVE BLOCK TECHNIQUE IN EXTRACTION OF MANDIBULAR POSTERIOR TEETH - A RANDOMIZED CLINICAL STUDY.

Abstract

BACKGROUND: Profound pulpal anaesthesia using the inferior alveolar nerve block (IANB) technique for extraction of mandibular posterior teeth is difcult to achieve. Several authors emphasised the effects of intraligamentary injection anaesthesia (ILA), also known as periodontal injection; as a primary or supplementary technique. The aim of this study was to compare the efcacy of ILA over IANB technique in providing adequate and superior anaesthesia for extraction of mandibular premolars and molars. MATERIALS AND METHODS: 30 patients requiring bilateral extractions of mandibular posterior teeth were selected. The parameters evaluated were subjective (numbness) and objective (pain on gingival probing) signs of anaesthesia, difference in pain perception during the procedure; and duration of anaesthesia for ILA (Group A) and IANB technique (Group B). RESULTS: The results showed that no difference was found in terms of subjective and objective evaluation of anaesthesia between the groups. A statistically signicant difference was seen in Group A, where intraligamentary injection anaesthesia showed less pain perception than the IANB technique. However, longer duration of anaesthesia was noted in Group B. CONCLUSION: With fewer failures and complications, the intraligamentary injection can be effectively used as a primary technique to alleviate pain and profoundly anaesthetize the mandibular posterior teeth during dento-alveolar extraction procedure.
