Can 4% Articaine Buccal Infiltration Replace Inferior Alveolar Nerve Block (IANB) with 2% Xylocaine for Pulp Therapy in Primary Mandibular Molars? A Systematic Review.

AIM AND OBJECTIVE

This systematic review aims to compare the efficacy of 4% articaine buccal supraperiosteal/infiltration to that of inferior alveolar nerve block (IANB) with 2% xylocaine in providing pulpal anesthesia for carrying out pulp therapy of deciduous mandibular molars in children.

MATERIALS AND METHODS

PubMed, Cochrane Registry, and Ovid SP were searched in the timeframe between years 1991 and 2020 with appropriate MeSH terms. Full texts were selected only after a preliminary screening of relevant titles and abstracts.

RESULTS

Five studies were involved for the final qualitative analysis. The parameter sought for was "Pain during pulp therapy after injection with buccal supraperiosteal/infiltration (4% articaine) or IANB (2% lignocaine) in primary mandibular molars. Three studies evaluated objective pain (operator reported) during pulp therapy, reported significantly lower pain scores with articaine buccal infiltration (BI). Among the two studies that evaluated subjective pain, one study reported a significantly lower pain score with the articaine BI group. The other study reported no difference statistically between both groups.

CONCLUSION

Under the bounds of this systematic review, BI with 4% articaine might be equivalent to IANB with 2% lignocaine for providing pulpal anesthesia required for pulp therapy procedures in primary mandibular molars; however, the quality of evidence is low, more number of well-controlled studies with adequate sized sample should be conducted out to verify the same.
