XP-endo Finisher optimal cleaning while preserving dentine

The problem The complexity of the root canal The root canal system is highly complex: it can be oval or C-shaped; the canals sometimes divide; or an isthmus may connect the canals (Dye and Micro CT 3D studies). In the face of such complexity, standard NiTi files are not always up to the task. Despite their flexibility, the files make round shapes only and thus cannot reach certain parts of the canal during treatment. Several studies involving micro CT technologies have shown that, on the whole, when standard NiTi files are used to prepare the root canal, only 45-55 per cent of canal walls...

The solution XP-endo Finisher Original canal anatomy Dentine The canal (area to be cleaned) Area cleaned Root canal preparation with standard NiTi files Canal partially cleaned. Microbes and dental debris accumulate in the untouched areas. Root canal preparation with standard NiTi files + XP-endo Finisher XP-endo Finisher idealy used following any root canal preparation to achieve an improved cleaning of the root canal while preserving dentine. XP-endo Finisher is incredibly flexible and can expand its reach 6mm in diameter or 100-fold of an equivalent sized file. This is why XP-endo...

Expansion capacity Its capacity to expand improves its reach 100-fold compared to a standard instrument. Standard Instrument XP-endo Finisher XP-endo Finisher is able to treat root canals with highly complex morphologies, from the narrowest to the largest, and from the straightest to the most severely curved canals. Because of its small core size – ISO 25 in diameter – and its zero taper, the file benefits from incredible flexibility and shows unparalleled resistance to cyclic fatigue. In addition the file will contact and clean the dentine but NOT change the original shape of the canal !...

Shape-memory effect The creation and production of XP-endo Finisherfiles are based on the shape-memory principles of the NiTi alloy. The file is straight in its M- phase which is achieved when it is cooled. When the file is exposed to the body temperature (the canal) it will change its shape due to its molecular memory to the A- phase. The A - phase shape in the rotation mode allows the file to access and clean areas that are otherwise impossible to reach with standard instruments. Soft shape Memorized shape Martensitic phase Austenitic phase The file can be returned to its original...

A universal NiTi-based instrument measuring ISO 25 in diameter and with zero taper (25/.00). Unique characteristics Mechanical cleaning of the canal in areas previously impossible to reach thanks to its incredible flexibility and capacity to expand its reach 6mm in diameter or 100-fold of an equivalent sized file. Unprecedented resistance to instrument fatigue thanks to its zero taper and the ability of the file to work in mixed M and A phases (exclusive FKG MaxWire alloy). Adaptation to canal morphology and preservation of the dentine. Thorough removal of debris. Removal of medication from...

Case 2 Internal resorption case demonstrating the expansive potential of the XP-endo Finisher. *Courtesy of Dr. Gilberto Debelian (Norway) Golden rules XP-endo Finisher should be used only after canal preparation to at least #25. In multirooted teeth, start with the largest canal. Work along the entire length of the canal for approximately one (1) minute. The access cavity should be filled with irrigant only after the XP-endo Finisher is in the canal.

Use XP-endo Finisher only after canal preparation to at least #25. For multirooted teeth, start with the largest canal. The canal should always contain irrigant. However, avoid filling the access cavity with irrigant before insertion of the file. Remove the XP-endo Finisher from the sterile blister pack and place it in a contra-angle handpiece (use of gloves imperative). Fix the canal working length by using the plastic tube (a) to adjust the rubber stop (b) (Figure 1). Cool the XP-endo Finisher down inside the tube using a cold spray. Put the XP-endo Finisher in rotation mode and remove it...

6b If the file is straightened outside the tube use an alcohol soaked gauze for this purpose to avoid contamination and warming of the file. 7 Insert the XP-endo Finisher into the first canal of the tooth while straight (Figure 3). Once the tip is inside, turn on the rotation and insert file (Figure 4). Add irrigant to the access cavity. 7a In case of any difficulty inserting the file inside the canal of multirooted teeth, make sure to direct the tip of the file towards the mesial aspect of the canal entrance for MB, ML and DB canals, towards the palatal aspect for palatal canals and toward...
