A width of the longitudinal cavity is greater at the open base of the plug and narrower towards the closed tip of the plug, the longitudinal cavity being configured to accept an injection tube connected to the injection device for filling the plug towards a root of a tooth. The longitudinal cavity comprises at least one lateral longitudinal opening in the wall of the plug, the at least one lateral opening being configured to, in use, enable a tooth filling material to pass through the at least one longitudinal opening and into a tooth. ## Claims ### Claim 1 An endodontic apical plug comprising: a side wall extending between an open base and a closed tip, wherein the wall defines a longitudinal cavity extending from the open base of the plug to the closed tip of the plug, wherein a width of the longitudinal cavity is greater at the open base of the plug and narrower towards the closed tip of the plug, the open base being configured for insertion therein an injection tube for inserting the plug towards a root of a tooth, and the longitudinal cavity being configured for injection therein, through the injection tube, tooth filling material; and wherein the side wall includes at least one lateral opening, wherein each lateral opening longitudinally extends along said side wall from said open base to said closed tip and being configured to distribute the tooth filling material from the longitudinal cavity into the root of the tooth said opening being configured such that the pressure of the tooth filling material is distributed from down upward. ### Claim 2 (depends on 1) The endodontic apical plug according to claim 1, wherein at least two lateral longitudinal openings are provided in the wall of the plug. ### Claim 3 (depends on 1) The endodontic apical plug according to claim 1, wherein at least three lateral longitudinal openings are provided in the wall of the plug. ### Claim 4 (depends on 1) The endodontic apical plug according to claim 1, wherein the lateral longitudinal openings have an elliptical shape. ### Claim 5 (depends on 1) The endodontic apical plug according to claim 1, wherein the closed tip of the plug is provided with an elliptical cross sectional shape. ### Claim 6 (depends on 1) The endodontic apical plug according to claim 1, wherein the closed tip of the plug is made of a material which is the same as a material in which the walls and open base are made of. ### Claim 7 (depends on 1) The endodontic apical plug according to claim 1, wherein the wall close to the closed tip of the plug is provided with a leak resistant cap portion comprising a first flange and a second flange. ### Claim 8 (depends on 1) The endodontic apical plug according to claim 1, wherein the open base is provided with double edge configured to prevent leakage and to aid connection of the injection tube to the open base. ### Claim 9 (depends on 1) The endodontic apical plug according to claim 1, wherein the injection tube is a needle. ### Claim 10 (depends on 1) The endodontic apical plug according to claim 1, wherein an outer surface of the wall is provided with at least one guiding wing configured for guiding the plug into the root of the tooth. ### Claim 11 (depends on 1) The endodontic apical plug according to claim 1, wherein the wall is provided with at least two guiding wings. ### Claim 12 (depends on 11) The endodontic apical plug according to claim 11, wherein the guiding wings are discontinuous guiding wings with spaces between each discontinuous portion of the guiding wing, and wherein the guiding wings do not cover any of the longitudinal openings. ### Claim 13 (depends on 11) The endodontic apical plug according to claim 11, wherein the cross-sectional profile of the guiding wing comprises a rounded shape. ### Claim 14 A kit of parts comprising: an endodontic plug having a side wall extending between an open base and a closed tip, wherein the wall defines a longitudinal cavity extending from the open base of the plug to the closed tip of the plug, and an injection tube configured to be inserted inside said open base and for injection tooth filling material inside said longitudinal cavity; wherein a width of the longitudinal cavity is greater at the open base of the plug and narrower towards the closed tip of the plug, the open base being configured for insertion therein an injection tube for inserting the plug towards a root of a tooth, and the longitudinal cavity being configured for injection therein, through the injection tube, tooth filling material; and wherein the side wall includes at least one lateral opening, wherein each lateral opening longitudinally extends along said side wall from said open base to said closed tip and being configured to distribute the tooth filling material from the longitudinal cavity into the root of the tooth said opening being configured such that the pressure of the tooth filling material is distributed from down upward.
