RESUMEN DE ARTÍCULO CITADO:

ABSTRACT:

This study was conducted to evaluate the effects of dimercapto succinic acid (DMSA), and sodium hypochlorite when used alone or in combination, as an irrigant in root canals. Thirty five freshly extracted maxillary central incisors were divided in five groups with five teeth each in group A, D and E, while 10 teeth in group B and C. Group A was the control group in which only distilled water was used as an irrigant. Group B was irrigated with 1ml of 10% DMSA solution. In group C, 5% NaOCl was used as irrigant. Group D was first irrigated by 0.5ml of DMSA followed by 0.5ml of 5% NaOCl. In the last group i.e. group E, first 0.5ml 5% NaOCl was followed by 0.5ml 10% DMSA. The specimens were examined under scanning electron microscope. The thickness of smear layer and the diameter of open dentinal tubules were measured and statistical analysis was done. Results indicated that the control group had no open tubules and the whole canal surface was packed with debris and smear layer. In group C, the superficial loose debris was cleaned and few open dentinal tubules were noticed but amorphous layer was still present. In case of group B and E the inorganic component of smear layer was removed but an organic layer persisted. The thickness of the remaining smear layer and tubule opening was comparable in both these groups, but was statistically significant when compared with group C. Group D showed almost no smear layer and maximum opening of tubules (3.0 – 13.0m in diameter) when compared to other groups. This study obtained promising results when combination of DMSA and NaOCl was used as an endodontic irrigant.
