Abstract EN
ecently a mixture of a tetracycline isomer, an acid, and a detergent, combined in a product called MTAD has been suggested as a final rinse to remove the smear layer from the surface of instrumented root canals.
The purpose of this study was to investigate the influence of MTAD and alternate use of EDTA and MTAD with NaOCl on the apical microleakage of obturated root canals.
In this study 60 maxillary central incisors were decoronated at cemento-enamel junction.
The roots were divided into six groups of ten teeth each according to irrigation regimens used during preparation of root canals as follows: Saline, NaOCl, MTAD, NaOCl / EDTA, NaOCl / MTAD, and NaOCl / EDTA / NaOCl.
After cleaning and shaping, roots were obturated with gutta percha and Endofill root canal sealer using lateral condensation technique and incubated at 370C for 48 hours.
The roots were coated by nail varnish and immersed in india ink then rendered clear by using 10% nitric acid and methyl salcilate.
Dye-penetration extent was measured using stereomicroscope.
The results of this study showed that roots irrigated with NaOCl / MTAD had a significantly least mean extent of dye-penetration values compared with all irrigating regimen except NaOCl / EDTA.
In conclusion the final rinse with either MTAD or EDTA following 2.5% NaOCl irrigation could reduce the root apical microleakage.
