Title: Stopping of root canals in the temporal and second teeth at children with accounting the state of root. Types of the roots stopping. Testimony. Technique of stopping of root

Stopping of root canals in the temporal and
second teeth at children with accounting the
state of root. Types of the roots stopping.
Testimony. Technique of stopping of root
After a sciagraphy picture distinguish 5 stages
of development of root of tooth and per?odont
  • ?- the stage of growth of root in length
  • II- the stage of the unformed apex
  • III- the stage of the unclosed apex
  • IV- the stage of unformed per?odont
  • V- the stage of the fully formed root and

Distinguish 3 types of rezorbation of roots of
temporal teeth (T. F. Vinogradova, 1967).
  • The first type is characterized by even
    rezorbation of all roots of, which begins in the
    area of apexes and spreads in vertical direction
    the signs of rezorbation in the area of
    bifurcation are minimum, rezorbation of roots
  • For a 2 type the characteristic is that next to
    partial rezorbation of roots and rezorbation of
    one root prevails in the area of bifurcation,
    that reverse to the rudiment of the second teeth
    at overhead large cheek-teeth this above all
    things disto - buccal root, in lower is distal.
  • For a 3th type characteristic predominance of
    rezorbation in the area of bifurcation the
    maintainance of morphological safety of apex part
    of root is possible. In the area of ??????????
    often there is connection with crown pulp.

Delivery of Irrigants Syringe Commercial
endodontic syringes have a fine bore to allow
delivery of irrigant into the apical part of the
root canal system. Gauge 27 needles are
manufactured with a cut away tip to allow
irrigant to pass out sideways and reduce the risk
of apical extrusion.
A Monoject syringe, which has a safe-ended tip
Placing a rubber stop on the needle will prevent
extrusion of irrigant beyond the apex of the
Prebending the needle against a ruler

Intracanal medicaments are advocated to
Eliminate bacteria after chemomechanical
instrumentation Reduce inflammation of the
periapical tissues Dissolve remaining organic
material Counteract coronal microleakage.
Properties of resorcin - formalin liquid
  • The act of this liquid (mixtures) is based on
    destroying microorganisms the pair of
    formaldehyde and near apical property of
    resorcin. A liquid easily fills root-canals,
    deeply penetrate in dentinal tubulis and after
    polymerization locks them, insulates a root-canal
    from periodontitis. Getting to periodont, a
    liquid destroys ephithelial mews and granulation
    fabric. Reactive inflammation which arises up
    ends with scarring and formation of bone fabric.
    It is negative property of resorcin - formalin
    liquid colouring tooth in a rose color. To
    prevent colouring, insulate the crowns of the
    tooth to treatment a crown is oiled by Vaseline
    or is inundated by a beeswax, gypsum, dentine,
    abandoning opening for penetration in a
    root-canal before the isolation of crown of the
    tooth in a root-canal enter and abandon a root
    needle with a roller, which is then drawn out.
    After treatment of root-canals by a impregnation
    method they are stopped by paste, to cements.

Technique of preparation of resorcin - formalin
  • A liquid is prepared immediately in front of
    application consistently mix up two parts of
    formalin, two parts of resorcin, one part I will
    rub caustic the warm liquid (mixture) of
    darkly-cherry blossom appears. In a few hours
    this liquid acquires oily consistency viscid,
    then hardens and is done glassy.

  • Stopping of root-canal at patients with
    per?odontitis is the important stage of
    endodontical therapy. Two basic tasks decide in
    the case of high-quality his implementation.
    Foremost, stopping of channel has for an object
    to create a barrier between the external and
    internal environments of organism. The features
    of morphology of cavity of tooth do not allow
    fully to delete the organic matters which
    disintegrated, and also attain the state of
    sterility of channel. That is why air-tight
    stopping of channels is the unique mean of
    blockade and rendering harmless of toxic products
    of disintegration and microorganisms in a
    channel, apical delta and dentinal tubulis.
  • Secondly, a mean which fills a channel
    unavoidable contacts with per?odont, that is why
    he must be the neutral matter biologically, to
    correct not the irritating operating on fabrics.
    The channel stopping must guard per?odont from
    external irritants. In addition, as there is an
    inflammatory process in periapical fabrics,
    stopping must act part of original medical
    bandage, which corrects the medicinal operating
    on inflammation and thus stimulates the processes
    of regeneration. This role of the channel
    stopping can be realized, foremost, on condition
    of its introduction to the root-canal and dense
    filling him to per?odont. Only in such case terms
    are created for biological influence on a
    pathological hearth in periapical fabrics.

At the end of the XIX item such requirements
belonged to the channel stopping
  • Stopping not must disintegrate.
  • It must be antiseptic characteristics.
  • Not must correct the irritating operating on
    per?odont and periapical fabrics.
  • Not must have pore and suck in secrets which are
    selected from a periapical area and is
  • Material of stopping must be easily brought into
    a root-canal.
  • Material of stopping not must decolorize tooth.
  • Material of stopping must be readily-removable
    from a channel.

Gofung (1943) added the followings requirements
to stopping
  • 1 Stopping must achieve apex, densely filling a
    channel and dentinal tubulis.
  • 2 To be X ray contrast.
  • 3 To render harmless maintenance of root-canal,
    forming the compound with him.
  • 4 To be not washed by a tissue liquid which goes
    out from a periapical area.
  • 5 Must fill not only a basic channel but also
    lateral channels of root.

In our time for the best choice of the endocanal
stopping main its properties are incorporated in
3 groups.
  • I. Biological properties
  • Endocanal stopping not must damage periapical
  • Must correct the protracted antibacterial action.
  • Must stimulate reparetion processes in per?odont.
  • Not must sensibilisate organism and to have
    antigens internalss.
  • II. Physical and chemical
  • 1. Endocanal stopping must have high adhesion, to
    provide its tripping with the walls of channel
    even in the conditions of humidity, densely to
    close the apical opening and dentinal tubulis.
  • Not must change physically, that to have not pore
    and contraction.
  • Not must change chemically, that to dissolve not
    in a tissue liquid.
  • To be X ray contrast.
  • To paint not a tooth.
  • III. Technological (practical)
  • Endocanal stopping is guilty it is easily to
    prepare and be added to treatment.
  • To be plastic and it is easily to fill a channel.
  • 3. To be added to deleting from a channel in the
    case of necessity.

To pasture on the basis of hydrooxide of calcium
  • Due to the reaction (?? about 12) hydrooxide of
    calcium at filling to them of root-canal operates
    bactericidal, destroys necrotizing fabrics,
    stimulates osteo-,dentine- and cementogenesis.
    Application of incongealable paste on the basis
    of hydroxide of calcium is rotined for the
    temporal stopping of channel in treatment of
    destructive forms of per?odontit, cyst -
    granulation and root cysts.
  • Carefully treated instrumental and medicinal a
    channel is filled by paste by canalfiller. At
    destructive forms the leadingout is recommended
    to pasture for an apex. A tooth is closed by an
    air-tight bandage. In 34 weeks hydroxide of
    calcium in a channel is replaced by fresh
    portion, and then one time in two months. After
    achieving a positive result a channel is cleared
    and is stopped by permanent solidifiable
  • For the temporal stopping of root-canals such
    preparations are produced on the basis of
    hydroxide of calcium "Kalasept" (Skania Dental),
    "Multi-Cal", "Tempkanal" (Pulpdent), "Sealapex"
  • Some of them contain iodoform "Endocal"
    (Septodont), "Vitapex" (Japan), "Metapex"
    (Korea), hydroxiapatit "Cal Ultra" (Ultradent)
    kortizon "Biocalex" (Slump).

Classification of materials for the permanent
stopping of root-canals 1. Pastes-encapsulants
which harden. Simple (on zincoxideevgenol basis,
zincoxideevgenol paste and polymeric (synthetic
"?? 26", "Plus AH", Dentsply "Diaket",
ESPE). With the therapeutic action (on
zincoxideevgenol basis "Endospad", Dentsply
"Pulpispad" "Endometasone", Septodont and on
polymeric basis "Sealapex", Kerr).

2. Primary hardening fillers.
  • Plastic (gutta-perchas pins).
  • Hard(silver pins).
  • Combined ("Thermafil", Dentsply).

Depophorez by copper-calcium hydroxide
  • This method combines medicinal treatment and
    stopping of root-canal. A method is developed and
    scientifically grounded by the known professor
    German by a scientist-chemist A. Knapvost.
  • Testimony. Depophorez is rotined at treatment of
    teeth with gangrenous content of channels, with
    devitaelising tailings of mash, fi channels, at
    granulomatous per?odontit, roots cysts, presence
    of perforations, with the wreckages of
    instruments, and also teeth, earlier treatment
    without result by a endodontical method.
  • The strong bactericidal action and deep
    penetration of the steady-state system of
    hydroxide of copper-calcium of ?u??(O)2 of lies
    in basis of method, that consists of 3 active
    components ions of hydroxiapatit, ions of
    colloid hydroxide of copper and hydroxylic ions.
  • Hydroxide of copper-calcium is effective against
    anaerobic bacteria and mushrooms aerobic his
    polyvalency bactericidal action by the ions of
    copper of Cu or Cu(OH) 42" is provided due to
  • to the proteolisis action of ??-ions
  • to destruction of hydroxicopper albumens of
    microorganisms by deleting of sulphur from amino
  • disintegration membranes of microorganisms
    and their spores forms.
  • Duration of the bactericidal influencing of
    hydroxide of copper-calcium is based on ability
    of sulfide of copper under the action of oxygen
    again to grow into the sulfate of copper of,
    which is able again to enter into the reaction
    with the sulfur-containing albumens of microbes.
    That is why disinfectant ability of ions of
    copper recommences constantly.

  • Name all types of stopping of root-canals the
    roots stopping by a gutta-percha.
  • This
  • it is stopping only by plastic stopping
  • stopping by pins is in combination with a filler
  • stopping by a gutta-percha.
  • . The same thingcones
  • method of central pin, or one cone
  • sectional method of stopping of channel.
  • method of cold lateral condensation of
  • method of hot lateral condensation of
  • method of vertical condensation of hot
  • stopping of root-canal by a
    termahplastic gutta-percha (systems of
    "Thermafil", "Quick-Fil").

Hot lateral condensation of gutta-percha
A cone is selected that corresponds to the apical
dimension and taper of the prepared root
canal. It is fitted to the working length with
A cold finger spreader is inserted alongside the
master cone and gentle lateral condensation is
applied. A heated spreader is then placed in the
space and used to adapt the gutta percha whilst
it is thermoplasticized. Spreaders should be
removed from the canal when they are cold to
avoid displacing the gutta percha. Pressure
should be applied to counteract the shrinkage
that occurs during cooling.
A light coating of sealer is placed on to the
walls of the root canal using a hand file,
endosonic file or gutta percha point.
An accessory cone is coated in sealer and
inserted into the space created by the
spreaders. The sequence for lateral condensation
is the same as before cold finger spreader first
followed by the heated spreader. Gentle lateral
forces are used to adapt the cones while cooling.
The gutta percha cones are cut off level with the
pulp floor using an electric heater tip or hot
instrument. Vertical pressure is applied with a
cold plugger for several seconds.
The process is repeated with more accessory
The down pack The cone is cut off level with the
pulp floor using the system B tip. Light
pressure is applied with a cold Machtou plugger
(Maillefer, Bellaigues, Switzerland). The
activated System B tip is plunged apically into
the gutta percha until the stop is 2-3 mm short
of the reference point. The wave of compaction
is continued without heat until the rubber stop
is at the reference point. Apical pressure is
applied for 10 seconds as the gutta percha
cools. A short burst of heat is applied and the
System B tip is removed. A cold plugger is used
to compact the apical segment of gutta percha.
