Repair of Furcal Iatrogenic Perforation with Mineral Trioxide Aggregate: Two Years Follow-up of Two Cases

Abstract

Furcal perforation is usually an undesired complication that can occur during preparation of endodontic access cavities or exploring canal orifice of multirooted teeth. Inadequacy of the repair materials has been a contributing factor to the poor outcome of repair procedures. On the basis of the recent physical and biologic property studies of the relatively new introduced mineral trioxide aggregate, this material may be suitable for closing the communication between the pulp chamber and the underlying periodontal tissues. There are few reports on repair of furcal perforation with MTA in molar teeth. The purpose of this case report was to describe the treatment of two furcal perforation using MTA in molar teeth. The perforations were cleaned with NaOCl and saline solution and sealed with MTA without internal matrix. Finally, the teeth were endodontically treated and coronally restored with composite resin and ceramic veneer crown and bridge. After 2 years, the absence of periradicular radiolucent lesions, pain, and swelling along with functional tooth stability indicated a successful outcome of sealing perforations in two cases.

Washout resistance of fast-setting pozzolan cement under various root canal irrigants

“…Among various materials, MTA has been recommended for the treatment of furcal perforations 7-9. Despite its many favorable properties, MTA has some drawbacks such as a long setting time, which is still problematic for clinical applications.…”

The effects of sodium hypochlorite and ethylenediaminetetraacetic acid on the microhardness of Mineral Trioxide Aggregate and TotalFill Bioceramic Putty

“…The literature suggests that waiting for a minimum of 4 h under a moist cotton pellet (with the other surface exposed to moisture from dentinal tubules) will allow MTA to set adequately to achieve optimum flexural strength via two‐sided hydration . However, the recall period following perforation repair material placement has not been standardised by clinicians and has been reported to range from a few days to a week .…”

Osteogenic cell response to calcium aluminate‐based cement

“…A material based on calcium aluminate cement (CAC+) has been developed (Patent number PI0704502-6, Pandolfelli et al 2007) as an alternative cement to mineral trioxide aggregate (MTA), which is the gold standard material for many challenging endodontic procedures such as root perforations, root resorption, pulpotomies and treatment of teeth with incomplete apices (Simon et al 2007, Jacobovitz & de Lima 2008, Unal et al 2010, Shahravan et al 2011. The physical and chemical properties of CAC+, its sealing ability, antibacterial property and bioactivity have already been demonstrated in previous studies (Pandolfelli et al 2007, Jacobovitz et al 2009, Oliveira et al 2010 Correspondence: Paulo Tambasco de Oliveira, School of Dentistry of Ribeirão Preto, University of São Paulo, Av.…”
