Abstract
AIM: The aim of this study was to evaluate and compare the apical microleakage of zinc oxide (ZOE) eugenol and Endoflas as obturating materials using different root canal irrigants in primary teeth. MATERIALS AND METHODS: A total of 80 extracted primary anterior teeth were divided randomly into four groups with different irrigants and obturating materials used. Group I [ZOE + sodium hypochlorite (NaOCl)], group II [ZOE + NaOCI + ethylenediaminetetraacetic acid (EDTA)], group III (Endoflas FS + NaOCI), group IV (Endoflas FS + NaOCI + EDTA). Cleaning and shaping of the root canals were done using specified irrigants, followed by obturation with ZOE eugenol and Endoflas as per the respective groups. Specimens were then immersed in 2% methylene blue dye solution and stored for 24 hours. The specimens were split longitudinally into two halves and observed under a stereomicroscope. Apical microleakage was measured from the apex to the most coronal extent of dye penetration. RESULTS: The highest dye penetration was recorded for teeth filled with ZOE, group I (ZOE + NaOCl), with mean values of 1.924 ± 0.925. Endoflas group IV (Endoflas + NaOCI + EDTA) showed the lowest dye penetration with mean values of 0.901 ± 0.255. There was a statistically significant difference between the ZOE and Endoflas groups (p < 0.001). The result showed a statistically nonsignificant difference between the two Endoflas groups (p = 1.000). Minimum microleakage was found in group IV (Endoflas + NaOCI + EDTA). CONCLUSION: Endoflas FS exhibits less apical microleakage than ZOE eugenol as an obturating material in primary teeth. Hence, Endoflas could be a potential alternative to ZOE eugenol with better sealing ability as an obturating material in primary teeth. Also, the addition of EDTA to irrigation protocol has shown a statistically nonsignificant improvement in microleakage reduction with both obturating materials.
