A root canal filling system is provided that allows for better control of temperature delivery, position and/or compaction forces of filling material when sealing root canals. First, the system employs a removable delivery device that allows for a thorough and precise heating of the filler material in vivo. Secondly, the system provides information related to the position of the filler material at the time of filling. Thirdly, the system increases the 3-dimensional packing forces applied to the filler material. The system comprises a holder and a filler material delivery device (or carrier). In its various embodiments, the system can additionally include a base unit and/or a plugger. The system (1) analyzes the position of the filler material in the canal prior to applying heat and packing force to the filler material, (2) heats the filler material such that the filler material is of a substantially uniform temperature, and (3) allows for packing or molding of the filler material while the delivery device is removed. These parameters can be programmed into an automated system. A plugger can be used as part of the system or independently of the system. A disclosed plugger comprises a plugging surface which contacts the filler material. The plugging surface comprises a plurality of moveable plates which move independently of each other. The movable plates enable the plugger surface to automatically and substantially instantaneously adjust in size and/or shape in response to the cross-sectional size and/or shape of a root canal as the plugger surface passes along the root canal.La présente invention a trait à un système dobturation de canal radiculaire qui permet dobtenir un meilleur contrôle de la fourniture de température, de la position et/ou des forces de compactage du produit pour obturation lors du scellage des canaux radiculaires. Dans un premier temps, le système emploie un dispositif dadministration amovible qui permet de chauffer avec précision et de façon mi
