Limonene extract as final irrigating solution in endodontic treatments

Limonene extract may have potential as a final irrigating solution in endodontic treatments.

Researchers evaluated its effect on push-out bond strength when used in teeth obturated with either epoxy resin-based or bioceramic root canal sealer. Its performance was compared with other irrigating solutions: sodium hypochlorite and ethylenediaminetetraacetic acid.

The in vitro study, published in Restorative Dentistry & Endodontics, found the combination of limonene extract with bioceramic sealer demonstrated superior push-out bond strength in the apical third.

Teeth obturated with epoxy resin-based sealer showed higher push-out bond strength when irrigated with ethylenediaminetetraacetic acid compared with sodium hypochlorite, particularly in the cervical third. Limonene extract yielded intermediate values without significant differences from the other irrigants. For teeth obturated with bioceramic sealer, the highest push-out bond strength was observed in the apical third, especially with limonene extract, differing from other thirds and final irrigating solutions.
