Objective   To evaluate the voids in root canal treatment of deciduous molar canals using three obturating materials and two obturation systems using micro-CT.  Study Design . Thirty freshly extracted deciduous molars were used in this study. The specimens were instrumented using a ProTaper Universal rotary instrument and randomly assigned into six groups ( n  = 5). Mesiobuccal root canals were obturated using Ca(OH) 2  and iodoform-Ca(OH) 2  and ZOE cement. The materials were applied straight from the syringe up to the 2 mm coronal level of the apex. Subsequently, the Lentulo spiral and ultrasonic activation with endoactivator were used for obturation. All samples were scanned by micro-CT with 9.1  μ m isotropic voxel resolution. The voids in cross-sectional images and 3D volumes of voids were measured. Differences among materials were statically evaluated ( p  < 0.05).Results   All study groups showed voids. Ca(OH) 2  and iodoform-Ca(OH) 2  with ultrasonic activation produced fewer voids whereas the ZOE groups showed higher voids with statistical significance ( p  < 0.05).Conclusions   Ca(OH) 2  and iodoform-Ca(OH) 2  with ultrasonic activation decrease void formation. Further studies should be done with other obturation techniques and materials for deciduous tooth root canal management.
