Background and aim: The mental-incisive nerve block can be used where lower premolars and anterior teeth require treatment. The aim of this study is to compare tow methods ofmental-incisive nerve block for extraction of the lower premolars and anterior teeth.
Methods and materials: This randomized double blind split-mouth clinical trial study was performed on patients requiring extraction of lower premolars and anterior teeth bilaterally. Patients were divided into two groups (case and controls). On one side injection was administered distal to the second premolar while on the other side the injection was done between premolars. The teeth were matched in terms of clinical and radiographic features.
Result: 40 patients (80 samples) with a mean age of 50.6 ± 12.7 were studied. According to the results, we had a 95% success rate with injection distal to the second premolar, but the success rate was 72.5% when the injection was done between premolars.
Conclusion: The mental-incisive nerve block with injection done distal to the second premolar was more successful than between premolars.
