What is used to melt gutta percha and place it as a temporary filling?

The Glick instrument is specifically designed for the purpose of melting gutta percha and placing it as a temporary filling in endodontic procedures. With its unique shape, which often features a paddle on one end, the Glick can be used to heat the gutta percha, allowing it to be manipulated and placed accurately within the tooth canal. This characteristic makes it particularly effective during various stages of endodontic treatment where temporary fillings are required.

In contrast, the other options do not serve the same function. An irrigating syringe is typically used for flushing and cleaning the canal with solutions, but it does not have the capacity to melt or place gutta percha. Cavit is a type of temporary filling material but is not an instrument; it does not melt gutta percha. Endo files are designed to clean and shape the interior of the root canal and do not possess the thermal properties required for melting gutta percha or the design needed for its placement. Thus, the Glick is the most suitable choice for this specific task.
