Comparing and evaluating the obturation techniques by 3 type of delivery system: An invitro method

Abstract

: The purpose of this study was to compare in vitro three methods of root canal obturation technique in deciduous dentition using conventional radiographic technique.: 45 root canals of primary molars were prepared by regular manual technique and obturated using zinc oxide eugenol and calcium hydroxide-based syringe form. Obturation methods compared were lentulo spiral, plugger and Iodontin syringe form. Conventional radiographic technique was used to evaluate the Root canal length, Obturation and the presence of voids. The obtained data were analyzed using Chi-square test.The results showed significant differences between the three groups for the radioopacity of obturation (P < 0.05). The results showed Iodontin syringe form has fewer voids compared to lentulo spiral ZOE paste and Plugger for obturation quality. Statistically significant difference was found between Iodontin syringe form and Plugger technique (p= <0.05).: Iodontin syringe form showed the best results in the length of obturation and as well as controlling paste extrusion through the apical foramen. The lentulo spiral and plugger can also be used as an alternative method.
