“…When the perforations were restored from the orthograde direction, IRM and MTA showed similar leakage. Blaney et al (1981) and Lee et al (1993) reported that MTA shows better sealing than IRM. These authors treated the perforated teeth from an orthograde approach; they reported that the mineral oxides in MTA reacted with the water from the surrounding tissues and activated a chemical reaction.…”

Quality and leakage of perforation repair-materials: A comparison of intracoronal and retrograde techniquesBackground: The objective of this in vitro study was to evaluate the quality and leakage of repair materials when perforation sites were challenged from an orthograde or retrograde direction. Methods:Intentional perforations were created on the mesial and distal root surfaces of the extracted human molar teeth (below the CEJ) using a diamond bur at a 45 degree angle to the long axis. Mesial perforations were repaired intracoronally using the following materials (n=15): IRM (Dentsply), amalgam (Dentsply), Dyract (Dentsply), SuperBond C&B (Sun Medical) and MTA (Dentsply). After filling the access cavities with cement, distal perforations were repaired retrogradely using the same materials. The teeth were kept at humid conditions (100%, 24hrs), the perforation sites were stained with 2%methylene blue (24hrs), sectioned and examined under a stereomicroscope at 20x and 40x magnifications and scored as extruded, insufficient or adequate in combination with the dye penetration. Results:The data was statistically analyzed (Kruskal-Wallis and Mann-Whitney U-tests). A significant difference was found among the restoration techniques (p<0.05). All the materials showed less leakage when used retrogradely (p<0.05). Repair of the perforation through the access cavity resulted in 86% extruded or insufficient restorations with leakage. IRM restoration showed 80% and MTA showed 60% adequate restoration without leakage when applied retrogradely. Conclusion:Repair of the perforations using the retrograde technique has significantly increased the number of the adequate restorations regardless the effect of the material factor. IRM showed the best sealing followed by MTA when applied retrogradely. KEY WORDSLeakage, MTA, perforation.Root perforation is a procedural error that can occur during endodontic or restorative treatments (Thesis and Fuss 2006). Apical, furcal and lateral root perforations can cause a chronic inflammatory reaction of the periodontium and may result in irreversible attachment loss (Seltzer et al 1970, Jew et al 1982. The prognosis of treatment involving a root perforation is questionable and depends on the accessibility of the perforation, the elapsed time after the perforation and the degree of contamination (Seltzer et al 1970, Sinai et al 1989, Fuss and Trope 1996. The success rate for treatment after a lateral root perforation is lower than treatment for other type of perforations because lateral root perforations occur close to the gingival attachment site and they can be repaired by an internal or external approach (Jew et al 1982, Martin et al 1982. Another important factor is the characteristics of the materials that are used for treatment (Lee et al 1993 2006, Fuss andTrope 1996). Several studies investigating these materials have reported that MTA has the optimal properties to manage perforations. 93The main component of MTA is calcium oxide and silicon dioxide (70% to 95% of the cement) .

“…These latter two materials are frequently used as temporary restorations either alone or in combination such as when a so-called "double seal" 50 is used -in such cases, Cavit is placed as an underlying material within the pulp chamber and then IRM is placed as the "external" material. [51][52][53] Some operators may use Cavit in conjunction with a GIC material in a similar manner with the GIC being used as the overlying interim restoration.…”

“…Most of these studies have not had any other form of restoration in the tooth and the ability of comprehensive interim restoration(s) to resist bacterial penetration has not been considered. 53,[63][64][65][66][67][68] Dye penetration studies are inexpensive and simple to conduct but no correlation has been established between the penetration of dye through restorations and that of bacteria. In addition there are no studies that compare the validity of dye studies to bacterial tracers.…”

One of the main aims of endodontic treatment is to eliminate micro-organisms from within the root canal system. A further aim is to prevent the ingress of any further bacteria during and after treatment. These aims are usually achieved by various means and stages throughout the treatment process. Endodontic treatment is usually performed on teeth that have lost the integrity of the external coronal tooth structure which has allowed bacteria to enter the tooth and ultimately reach the pulp space. Further opening of the tooth occurs when an endodontic access cavity is made to allow treatment to be performed. Hence, there will always be a need for interim and temporary restoration of teeth undergoing endodontic treatment. Many different materials and techniques have been proposed, and these proposals have been based on many research reports. The purposes of this article are to review the literature regarding the use of interim and temporary restorations, and to provide recommendations regarding such restorations for clinicians to follow when providing endodontic treatment.
