Comparison of Debridement Efficacy of Two Irrigating Systems Endovac and Conventional Needle in Primary Tooth Root Canals: An Study.

Aim: The purpose of the study is to evaluate how well the Endovac system and conventional needle irrigation work to remove smear layers (SR) from primary teeth root canals.

Materials And Methods: Fifty extracted human primary teeth were divided into two equal sections vertically, then positioned within an acrylic model that was secured with screws. Group A (Endovac), = 25, and group B (traditional needle), = 25.

Spinal Tap Needle Technique for Creating Apical Plug with Mineral Trioxide Aggregate in Immature Permanent Teeth.

Aim: This report evaluates the apical plug formation in two cases with necrotic immature maxillary central incisors in 11 and 12 years old female patients by the use of spinal tap needle to create apical plug-in single increment without any residual mineral trioxide aggregate (MTA) attachment to the wall of the root canal.

Materials And Methods: The shape of the immature root canal resembles a truncated cone. To achieve a truncated cone with MTA on the apical 4 mm in order to plug the open apex, the volume of material that will be required can be calculated by taking spinal tap needle (BD Spinal, Spain) equal to the last file used, in a way that the MTA extruded is equal to the amount required to shape the apical plug in a single increment.
