ROOT CANAL SEALERS
INTRODUCTION
SEALERS :These are Cements / Resins / Semiliquid / Plastic-which are
used as binding agents to fill up the gap between root canal and
obturating material.
- It also fills up the irregularities, discrepancies, lateral canals and
accessor canals.
- It helps to achie!e a proper apical seal.
IDEAL REQUIREMENTS
- The requirements of a suitable sealers used for filling the dr
canal in con"unction with gutta-percha / sil!er cone are as
follows#
$% It should be T&C'(, when mi)ed to pro!ide good adhesion
between the filling material and canal wall when set.
*% It should pro!ide a +RTIC S& an e)cellent seal apicall
and laterall%.
0% Should be R&1I2-2P&34, so that it can be !isuali5ed in a
radiograph.
6% Should not shrin7 upon setting 1I8SI28&( ST&9%.

Da7et A:
- Chemicall this sealer is similar to dia7et but it also contains the
disinfectant +&C+2R2P+8.
- It is one of the few medicated cements which does not contain
paraformaldehde.
TISSUE CULTURE STUDIES#
- 1ia7et is moderatel to)ic to cells.
- It has a strong ctoto)ic effect upto 6= hours after insertion.
HUMAN STUDIES#
- aterial is well tolerated b the Pa tissues o!erfillings with
1ia7et-& causes no inflammator reaction and are encapsulated
b fibrous connecti!e tissue%.

- The corticosteroids are now added to the cement separatel as
hdrocortisone powder / terra-cortil.
- The ob"ect of introducing formaldehde within the root-filling is
to obtain a continued release of formaldehde gas H which brings
prolonged fi)ation and antiseptic action.
TOICIT
- 9ecause of irritation is se!ere if forced into ma)illar sinus
mandibular canal-caused persisting, paresthesia.
- &PIC& S& H is better when compared to procosol, nongenol
and tubliseal and dia7et.

- & pin7 antiseptic powder is mi)ed with eugenol.
- Sometimes endomehasone RC sealers gi!es rise to pain /
discomfort after ; to = wee7s of insertion.
- This occurs because the corticosteroid mas7s an inflammator
reaction until it is remo!ed from the area.
- Paraformaldehde is not resorbed equall, quic7l and the
smptom of the inflammator reaction becomes apparent.
