![]() ![]() With the warm vertical compaction technique, which involves three to four warming and compaction cycles, the application of heat during down-packing is interrupted three to four times. Gutta-percha sealers: eucalyptol or chloroform used to dissolve the gutta-percha.The continuous wave of compaction technique was developed by Dr Stephen Buchanan in 1987 to simplify the warmed gutta-percha down-packing technique. Medicated gutta-percha: Gutta-percha points impregnated with chlorhexidine Calcium hydroxide or iodoform. Syringe system: Low viscosity gutta-percha is used, e g Successfil.īars/pellets gutta-percha: Used in thermoplasticized heating devices as small pellets and bars. Gutta flow: Here powdered gutta percha is incorporated in resin based sealer Carriers can be plastic materials, titanium or stainless steel. Precoated gutta-percha: Metallic carriers coated with gutta percha. Variable taper Gutta-percha: They have points suiting the taper of variable taper shaping instruments like Protaper F1, F2 and F3.Īuxiliary points: They are non-standardized gutta cones They behold the shape of root canal. They are available in 4%, 6%, 8% and 10% sizes.( Figure 1) Greater taper Gutta-percha: They have taper other than 2%. Gutta-percha points: They have size and shape similar to ISO standardization (2% taper from sizes No. Minimal supporting clinical data Questions raised over ease of removal for retreatmentĬore MaterialsA plethora of core materials are available to be used along with a sealer or cement ( Table 3) Hydrophilic No shrinking on setting Biocompatible Antimicrobial properties Triturated Long working time Fills canal irregularities with consistency BiocompatibleĮxpand slightly on setting Setting time is inconsistent Setting time gets delayed by use of sodium hypochlorite Some release formaldehyde when set Bond strenght compromised with use of chlorhexidine Bonding comparable to conventional sealers Good adhesion to the wall and core Do not contain eugenol Slow set Hard to remove in retreatment Minimal antimicrobial effectĪH-26 AH Plus Diaket EndoREZ Epiphany RealSeal Shrinkage on setting Soluble Can stain tooth structure May negatively affect bonding of core materials ![]() Long history of use will absorb if extruded Slow setting time Antimicrobial effect Radio-opaque Pulp Canal Sealer EWT Roth’s Sealer Tubli-seal Wach’s Sealer Hence, the objectives of this review paper are:Īdvantages and disadvantages of different commercially available sealers: ![]() Proper post-endodontic restoration pertaining to the coronal anatomy of the tooth being treated also plays an important role as studies provide reasonable evidence of coronal leakage and failure because of improper or fractured restorations or inadequate periodontal support present. Other factors that shall determine the clinical success of an obturation would include how and what are the materials used for obturation. ![]() 4 Achieving this goal shall primarily depend upon efficient bio mechanical preparation being carried out by a skilled clinician. 1, 2, 3 Clinician should choose a path of treatment that will result in best possible cleaning & shaping of the root canal system, coupled with an obturation technique providing a three dimensional complete seal of the entire root canal space. The clinical goal of a root canal obturation is to fill the empty spaces, achieve hermetic sealing and preventing any bacterial activity to infiltrate into the periapical tissues. ![]()
