This review article examines the need to seal the root canal orifice with glass ionomer cement beneath composite resin following endodontic treatment. The article summarizes various studies that have evaluated different materials for use as intracoronal seals, including glass ionomer cement, composite resin, mineral trioxide aggregate, and others. The results of these studies are conflicting, with some finding glass ionomer cement to be effective and others supporting alternative materials. Overall, the review was unable to definitively conclude whether an intracoronal seal is always needed or which material is best, finding that further high-quality research is still required to answer this question.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Critical Review on Glass Ionomer Seal under Composite Resin of
Obturated Root Canals
Ranya F. Elemam1,2
, Ziad S. Abdul Majid3
ORIGINAL RESEARCH
ABSTRACT
Introduction: The root canal treated teeth need an adhesive
seal for coronal leakage prevention. Glass ionomer sealant is
the usual interface used between the coronal restoration and
dental hard tissue however when composite resin material is
used as a coronal restoration, some dental clinician prefer not
to use it. The aim of this review is to determine the need to seal
the orifice of an obturated root canal with glass ionomer under
composite resin to prevent microleakage.
Material and methods: Electronic searches were performed
in the Pubmed and Scopus databases using relevant keywords.
Textbook searching was also applied. Following selection,
articles were fully reviewed to ensure that they met inclusion/
exclusion criteria.
Results: The intracoronal sealing abilities of a wide variety
of restorative materials have been investigated, assessed and
compared within the dental literature.
Conclusion: No definitive guidelines were found regarding
the use of orifice sealing materials following endodontic
treatment. This review was not able to answer the research
question, and further investigation is required to achieve this
goal.
Keywords: Intra-orifice barriers, Composite resin, Glass
ionomer, Micro leakage.
INTRODUCTION
Microbial infection via an inadequate coronal seal is one of
the major factors associated with endodontic failure,1
and
the literature suggests that coronal leakage is more likely to
determine clinical success or failure than apical leakage.2
Placement of a material over the coronal gutta-percha to act as
a barrier to coronal microleakage would be advantageous in
reducing leakage and increasing the possibility of treatment
success.3
The sealant material is placed into the canal orifice
following removal of the coronal portion of gutta-percha and
sealer. Many materials have been investigated for use as an
intra-coronal seal to prevent microleakage, including Cavit,
amalgam, intermediate restorative material (IRM), Super-
EBA, composite resin, glass-ionomer cement (GIC), and
mineral trioxide aggregate (MTA).1
Glass ionomer cement has been advocated for use as an
intracanal barrier when microleakage or recurrent caries are
likely because of its cariostatic and adhesive properties.4
Resin-modified glass ionomer material is one of the barrier
materials used routinely to close the canal orifice after root
canal obturation.5
It consists of glass ionomer and composite
resin, having properties of both materials. Composite resin
has excellent adhesive properties and is used commonly as a
core in endodontically treated teeth.6
The aim of this review is to determine if there is a need,
following endodontic treatment, to seal the root canal orifice
with glass ionomer beneath composite resin to prevent
microleakage.
MATERIALAND METHODS
Electronic searches were performed in the Pubmed and
Scopus databases using the keywords: intraorifice barriers,
composite resin, glass-ionomer, microleakage. Textbook
searching was also applied for relevant information. Articles
were first selected according to titles and abstracts, and
they were then fully reviewed to ensure that they met the
inclusion/exclusion criteria.
Inclusion criteria
Studies with all designs that used different materials and or
techniques included. The study should refer to intracoronal
orifice and micro leakage significance. Searches were limited
to papers written in English and published between 2002 and
2014.
The exclusion criteria
All studies that failed to meet the inclusion criteria. If a study
did not refer to the intraorifice barrier or explain its relation
with microleakage, it was discarded. Studies that discussed a
coronal barrier were also rejected.
RESULTS
Definition of an intraorifice sealing material and their
importance
The intra-orifice barrier is an effective treatment used in
endodontically treated teeth by introducing an additional
material into the canal orifice immediately after removal of
the coronal portion of gutta-percha and sealer.7
Coronal leakage is a primary cause of endodontic failure.8
Sealing of the coronal part of the root canal is therefore
indicated to reduce the chance of treatment deterioration.1
Sealing is of particular importance when the coronal
restoration is lost or inadequately placed,9
or when there is
delay in placing the final restoration.10

both anterior and posterior teeth.11
Cavit®
, amalgam, intermediate restorative material (IRM®
),
super-EBA, composite resin, glass ionomer cement and
mineral trioxide aggregate (MTA) are commonly used
materials.12,13
The use of colored materials is recommended
so they can be easily identified in cases of retreatment or
post restoration.11
Examples include the flowable composite
resins PermaFlo®
Pink or Purple (Ultradent), Flow-It®
dark
red (Pentron) or dark blue (DenMat).
The use of a resin-modified glass-ionomer material over
the gutta-percha followed by provision of a well-sealed
temporary or permanent filling is suggested.11
The sealing abilities of a variety of intraorifice restorative
materials and their capacity to prevent coronal micro leakage
have been investigated, assessed and compared.
MTA had the lowest rate of microleakage compared with
composite resin or light-cured glass ionomer1
following
completionofrootcanaltreatmentwithoutcoronalrestoration.
Sealing with Cavit®
gave better results than Vitremer®
(glass-
ionomer cement), and the flowable composite Flow-It®
.14
Composite resin used alone or combined with Coltosol®
showed a significant reduction in microleakage, whereas
glass ionomer combined with Coltosol®
resulted in less
microleakage than the glass ionomer used alone.15
In an evaluation of the necessity to use an intraorifice seal
in teeth with post space, a glass ionomer barrier over the
gutta-percha coulSd reduce the risk of recontamination of
the apical gutta-percha compared to those without glass
ionomer but sealed with Vitrabond®
.16
IRM®
and Coltosol®
were significantly better in preventing microleakage than
chemically cured glass ionomer and dentinal adhesive.17
In a
recent study the adhesive system CoroSeal®
reduced coronal
leakages more effectively than a flowable composite resin,
fissure sealant or polycarboxylate cement18
Figure 1.
DISCUSSION
Conventional root filling materials such as gutta-percha
and sealer do not provide adequate resistance to bacterial
microleakage.21,22
Therefore, the coronal part of the
root canal should be sealed to minimize the endodontic
treatment failure rate.3
Previous research support the use
of intra-orifice sealants, but there is little agreement on a
standardized protocol or material to be used as a coronal
barrier.23,24
Different studies have shown highly conflicting
results regarding the sealing ability of different materials.1
The following criteria have been proposed by Wolcott et al.
for an intracoronal barrier: (a) Easily placed by the specialist,
(b) Bonds to tooth structure (retentiveness),
(c) Effectively seals against microleakage,
(d) Easily distinguishable from natural tooth structure and
(e) Does not interfere with the final restoration of the access
preparation.
GIC is used commonly as an intraorifice barrier, and
according to Mavec et al.,25
the literature supports the use of
an intraorifice glass ionomer barrier to protect the root canal
filling as a second line of defense for the temporary coronal
seal.
In their study, Parekh et al.3
found that microleakage was less
beneath a seal of GIC plus composite resin as opposed to
composite resin alone, and concluded that “LCGIC + Tetric
N-Flow was found to be superior over other experimental
materials as intraorifice barriers.” They suggested that the
enhanced sealing ability of LCGIC may be attributed to:
1. Adhesion of LCGIC by development of an ion-exchange
layer adjacent to dentin and
2. Shear bond strength of LCGIC which is higher than
conventional GIC.
Divya et al.26
also concluded that a GIC and composite
combination can be recommended as coronal sealants, as did
Deepali et al.27
who stated they had the “highest probability
for achieving a maximal coronal seal.”
Other studies have recommended other sealing agents:
Slutzky- Goldberg et al.6
found GIC or MTA to be equivalent
in their sealing abilities, and the results of Jiang et al.28
suggest that flowable composites can serve as ideal intra-
orifice seals.
Mineral trioxide aggregate and flowable composite was
found to be preferred over glass ionomer as a coronal barrier
by Sagar et al.,5
while El-Kady29
concluded that the use of
a silorane based composite without the traditional glass
ionomer base was best to decrease leakage to the root canal
system.
CONCLUSION
The literature does not state clearly whether to use intra orifice
sealant materials beneath final and temporary restorations.
Although the routine is to place them under final restorations,
no study has supported a single protocol. Consequently this
review didn’t answer the research question, and a well-
designed investigation is required to achieve this goal.
