What is the disadvantage of finger spreaders as compared to standard long handled spreaders explain?
However, finger spreaders will not retain heat sufficiently for this procedure, and specially designed heat carriers should be used. The instruments have a sharp tip for lateral compaction, and a blunt plugger tip for limited vertical compaction of the softened gutta-percha.

What are finger spreaders used for?
Finger Spreaders are used to laterally condense gutta-percha points during root canal therapy.
Are finger spreaders single use?
A finger spreader – a typical single-use instrument. The plastic handle is designed for ease-of-use, not for ease of contamination.Apr 9, 2019
What is spreader in endodontics?
Endodontic spreaders are metal instruments used for packing root canal fill material to the sides of a canal in order to make room for additional material. These instruments can be handheld or machine driven, but they should always be tapered to fit the canal and properly sterilized for use.
What is a finger spreader used for?
Finger Spreaders are used to laterally condense gutta-percha points during root canal therapy.
What is finger spreader in dentistry?
A finely tapered, smooth-surfaced, flexible hand instrument used to laterally condense gutta-percha points during root canal therapy. The finger spreader is inserted between the canal wall and the gutta-percha point; after removal, a standardized accessory point coated with sealer is inserted into the residual space.
How do you select the spreader during obturation?
❖A spreader is selected that matches the taper of the canal and When placed in the canal it should be within 2 mm from the working length. ❖Selection of master cone: ❖Following canal preparation a master cone is selected that has a diameter consistent with the Master Apical File (MAF).
How do I choose a Endo spreader?
The size of the spreader is determined by the width of the prepared canal and the lateral fit of the primary cone. The greater the space between the canal wall and the butt-end of gutta-percha, the larger (wider) the spreader used.Oct 3, 2020
How do I choose an accessory cone?
Accessory cones are chosen based on the size of the spreader used, the size of the canal, and the position of space created in the canal (Table 7-3). For example, to the depth of the first spreader penetration, an accessory cone in the range of extra-fine to fine-fine is used.Feb 14, 2020
How do you choose a master cone for a root canal?
The principle: Creating a customized master cone may be considered a process of taking an impression of the apical part of the canal on the surface of a master cone. A gutta-percha cone is selected, which stops with a “tug-back” sensation at 3-5 mm short of the working length.
