Coronal seal
Studies have shown that the quality of the coronal seal has a
significant effect on the outcome of endodontic treatment with 
coronal leakage being associated with a less favourable result
15,16
. A
number of studies have shown that coronal leakage is reduced if 
the smear layer is removed
17
. Leakage will also be prevented if an
adhesive restoration is placed in the coronal aspect of the tooth, hence
the justification for placement of a resin-modified glass-ionomer
material over the gutta-percha followed by provision of a well-sealed
temporary or permanent filling.
