Delayed tooth replantation: MTA as root canal filling

Abstract

MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH) 2 . The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and bench-dried for 60 minutes. After root canal preparation, the teeth were assigned to two groups according to root canal filling material: I, calcium hydroxide; and II, MTA. The same treatment sequence was followed for both groups: coronal seal, periodontal ligament removal, immersion of the tooth in 2% acidulated-phosphate sodium fluoride, irrigation of the socket with saline and replantation. Both groups exhibited replacement resorption, areas of ankylosis and absence of inflammatory root resorption. Statistically similar results (p > 0.05) were observed for both groups regarding replacement root resorption, but the groups differed significantly (p < 0.05) regarding the occurrence of ankylosis. MTA may be a viable clinical option for filling teeth submitted to delayed replantation, and is an acceptable option for treating replanted permanent teeth in order to prevent tooth resorption, particularly when dressing changes are not possible.

Mineral trioxide aggregate and other bioactive endodontic cements: an updated overview – part II: other clinical applications and complications

“…, Panzarini et al . , Esteves et al . ), a number of case reports reported the successful treatment of inflammatory root resorption by placing either MTA or CEM cement as root filling materials following unsuccessful treatment with calcium hydroxide as a medicament an attempt to arrest inflammatory resorption (Aggarwal & Singla , Güzeler et al .…”

“…Several animal studies on primates and rats evaluated the effect of root filling or the placement of an apical plug of MTA Angelus, MTA Fillapex, white MTA Angelus and calcium hydroxide in teeth with immediate and delayed replantation (Panzarini et al . , , Marão et al . , Esteves et al .…”

“…In contrast, others reported that MTA Angelus and white MTA Angelus was associated with a significantly better outcome following delayed replantation (60 min) in terms of preventing both ankylosis (Panzarini et al . ) and inflammatory resorption (Marão et al . , Esteves et al .…”

Effectiveness of a Novel Calcium-enriched Mixture Root Cement to Decelerate Replacement Resorption in Replanted Teeth: A Case Report

“…23 They have excellent sealing property and biocompatibility. 24 Panzarini et al 25 demonstrated smaller areas of ankylosis when MTA was used as root filling material in comparison with CH, in a study involving delayed replantation of teeth in monkeys.…”

Influência do meio de conservação e efeito do tratamento de superfície na anquilose e na reabsorção de tecidos mineralizados após o reimplante de dentes avulsionados

“…Assim, a pasta à base de hidróxido de cálcio foi utilizada, no presente estudo, como medicação intra-canal em todos os grupos, por simularem um reimplante tardio, tendo em vista que a medicação poderia ser somente introduzida no canal radicular de maneira retrógrada. No entanto, em um estudo mais recente que avaliou o processo de reparo, após reimplante tardio em dentes de macaco obturados com hidróxido de cálcio e MTA, foi demostrada uma maior ocorrência de anquilose nos dentes obturados com hidróxido de cálcio (Panzarini et al, 2014b).…”
