摘要： A set of files (140A, 140B, 140C, 140D, 140E) have tip diameters which increase from 0.075 mm for file 140A to 0.175mm for file 140E in increments of 0.025mm. Each file has a flute length of 16mm. The maximum flute diameter increases proportionally from 0.235mm for file 140A to 0.975mm for file 140E. Tapers increase in 0.01 mm/mm increments from file 140A with a taper of 0.01 mm/mm to file 140E with a taper of 0.05 mm/mm. This assortment of increasing tip diameters and tapers with increasing file size allows a 0.15mm file maximal stiffness which is needed when attempting to find and enter an occluded calcified canal prior to shifting to a 0.075mm file which provides the maximum tactile response when negotiating the often tortuous terminal aspect of a canal after coronal enlargement with the larger file.

摘要： A dental instrument adapted to be used as a file or reamer for removing dead or damaged tissue from the root canal of a tooth. The instrument comprises a body part, of which solely the proximal part is shown, an intermediate part and a shank, these three parts preferably being integral with each other. The shank is adapted to be inserted releasably in a chuck, so that it may be driven to rotation when the instrument is used for treating the root canal of a tooth (not shown). A fracture groove between the intermediate part and the shank ensures that fracture occurs at this location, if the body part gets stuck in a tooth, thus avoiding the risk of small distal parts of the instrument being left in the root canal in a manner making it impossible to remove them.

摘要： La longueur de la partie active de chaque foret du jeu est inversément proportionnelle au diamètre de la tête coupante (1 1 b , 1 2 b , 1 3 b , 1 4 b , 1 5 b , 1 6 b ) de chaque foret, ce qui évite que les forets du jeu ne soient engagés dans le canal coronaire trop profondément, dès lors que la profondeur de travail dépend précisément du numéro de foret utilisé.

摘要： La conicité de la partie postérieure des instruments (1 a à 1 e ) d'un jeu d'instruments, située au-delà du diamètre D 9 de ces instruments, augmente plus pour les premiers instruments du jeu que pour les derniers. Au contraire, la conicité de la partie antérieure des instruments (1 a à 1 e ) du jeu n'augmente pratiquement pas pour les premiers instruments du jeu mais pour les derniers seulement. Il résulte de cette disposition qu'en utilisant successivement les instruments (1 a à 1 e ) du jeu, le praticien alèse tout d'abord la partie coronaire de la dent, puis sa partie médiane, et enfin la partie apicale. La partie terminale des instruments, entre la pointe de ceux-ci et leur diamètre D 3 situé à 3 mm de la pointe, présente une ou plusieurs gorges d'évacuation des déchets dentinaires mais qui sont dépourvues de lèvres coupantes de sorte que cette partie des instruments ne sert qu'à leur guidage.

摘要： A dental treatment instrument for the retrograde treatment of root canals (2) has at least one elongated shaft (12) ending at a point (7) and linked to a handle. The point (7) is bent by about 90° with respect to an axis defined by the longitudinal extension of the shaft (12) or handle. A head (14), in particular a rotationally symmetrical head (14), is provided at the free end of the point (7) for preparing a cavity (9) in the area of the root apex, in particular a cavity having an undercut (8), or for introducing filling material into said cavity (9), the diameter of the cavity (9) being lower than the root apex (3). For that purpose, in the cross-sectional view, the diameter of the head (14) in a direction perpendicular to the longitudinal extension of the point (7) is larger than the diameter of the head (14) in the direction of the longitudinal extension of the point (7).

摘要： A method of obturating an extirpated root canal (22) and an associated filler material (50 and 62) utilizes two classes of gutta-percha, one class (50) of which becomes plasticized at a predetermined temperature and the other class (62) of which becomes plasticized at a temperature which is less than the predetermined temperature. In one embodiment of the method, the second class of gutta-percha is coated about the first class when in a plasticized condition, and in another embodiment of the method, the second class is pre-coated about the first class and the second class is heated to plasticize condition without plasticizing the first class. In either case, the first class of gutta-percha supports the plasticized second class when subsequently introduced into a root canal for filling the canal. To increase the rigidity of the first class of gutta-percha, the first class may be coated with a cured (58) layer of methyl methacrylate before the second class of gutta-percha is coated about the first class. Following introduction of the two classes of gutta-percha into the canal, the classes may be condensed within the root canal system.
摘要翻译：填充拔除根管和相关填充材料的方法利用两类gutta-percha，其中一类在预定温度下变形，另一类在小于预定温度的温度下变形。在该方法的一个实施方案中，当处于增塑状态时，第二类gutta-percha围绕第一类涂覆，并且在该方法的另一个实施方案中，第二类是关于第一类预涂，而第二类是加热至塑化条件，不会使头等塑化。在任何一种情况下，第一类gutta-percha在随后被引入根管以填充运河时支持塑化的第二类。为了提高第一类牙釉质的刚性，第一类可以在第一类包衣之前涂覆甲基丙烯酸甲酯的固化层。在将两种类型的牙龈穿入运河后，这些类可以在根管系统内浓缩。

摘要： A composition for endodontically treating a root canal is provided. The composition uses a thermoset resin based material adapted for insertion into the root canal of a dental patient and an adhesive material suitable for maintaining the polymer based material in the root canal. Either one or both of the thermoset resin based material and the adhesive material is conductive. As a result, the dental practitioner is able to determine where the apex of the root canal is located by means of measuring the conductance between the thermoset resin based material and the oral mucosa and periodontal ligament. This facilitates the filling of the root canal with the polymer based material.
