Abstract

Background:  Many advanced techniques in local anaesthesia have been introduced for the      painless intra oral injections. To date, palatal injections are known to be the most painful          injections due to firm adherence of mucoperiosteum and abundant nerve supply. The aim of the present study is to assess the requirement of palatal injection with 2% lidocaine for the extraction of maxillary premolars and third molars. Materials and Methods: This prospective randomized single blinded split mouth case control study was done on 150 patients which were allocated in to four groups. Group 1 included patients indicated for extraction of maxillary premolars with buccal infiltration and without palatal infiltration. Group 2 included patients indicated for extraction of maxillary premolars with buccal infiltration and palatal infiltration / greater palatine block. Group 3 included patients indicated for extraction of maxillary third molars with buccal infiltration and without palatal infiltration / greater palatine nerve block. Group 4 included patients indicated for extraction of maxillary third molars with buccal infiltration and palatal infiltration / greater palatine nerve block. Pain during injection and extraction was assessed through Visual Analog Scale (VAS). Results were subjected to statistical   analysis and unpaired t test was done. Results: VAS score during injection in control groups (2 and 4) were high when compared to test groups (1 and 3) and the values were statistically significant (p=0.0001, p=0.0001). VAS values after extraction in both test (1 and 2) and control groups (3 and 4) were found to be statistically insignificant (p = 0.15, p = 0.92)  Conclusion: The routine use of painful palatal injection for the removal of maxillary premolars and third molars can be avoided in most of the cases.
