Intracanal dressing and root canal filling materials in tooth replantation: a literature review

Abstract

The prognosis of tooth replantation is usually related to the need of endodontic treatment, which has a direct relationship with the occurrence of root resorptions. Several studies have been undertaken in an attempt to prevent, delay, or treat these complications, which are the main causes of loss of replanted teeth. This literature review examines research evidence on intracanal dressings and root canal filling materials used in cases of tooth replantation. A comprehensive search was performed in the Medline/Pubmed, Bireme and Scielo full-text electronic journal databases to retrieve English-language articles referring to these topics that had been published between 1964 and 2010. Calcium hydroxide (CH) remains the usually recommended choice as an intracanal medicament in replanted teeth; however, there is evidence to support the initial use of a corticosteroid-antibiotic combination such as Ledermix paste to control potential early resorption, prior to the introduction of CH where the beneficial effect in the treatment of progressive root resorption has been well proven. Regarding root filling materials, CH-containing sealers are a good option because of their biological properties. Accurate diagnosis and adequate treatment plan may constitute very complex tasks, particularly in tooth avulsion because several variables are involved. In addition to the technical knowledge and clinical experience directed toward the quality of treatment, patient education may favorably influence the survival of replanted teeth.

Effects of Alendronate on Osteoclast Formation and Activity In Vitro

“…Despite great effort, the antiresorptive agents tested to date fail to avoid inflammatory resorption followed by ankylosis in dental avulsion cases (35). Furthermore, the therapeutic inhibition of bone resorption by BPs seems to decrease after dosing is stopped, indicating that the bound drug is not totally biologically active (5,6).…”

Revascularization Technique for the Treatment of External Inflammatory Root Resorption: A Report of 3 Cases

“…EIRR treatment protocol includes disinfection by irrigation and the use of calcium hydroxide as intracanal medication of choice for RCS disinfection (2)(3)(4). To arrest the resorption, the replacement of the calcium hydroxide paste is necessary, requiring several appointments for maintenance of calcium hydroxide in the RCS for long-term (2).…”

Curcumin in Combination with Piperine Suppresses Osteoclastogenesis In Vitro

“…The antiresorptive agents tested to date fail to avoid inflammatory resorption that is followed by ankylosis in dental avulsion cases (6). In a previous study we tested the anti-osteoclastogenesis effects of alendronate, a potent bisphosphonate used for osteoporosis treatment.…”

“…The majority of the replanted teeth have to be extracted within a period of 4-6 years (5). Many antiresorptive agents have been evaluated in vitro and in vivo and have been demonstrated to be either only partially effective or associated with unacceptable side effects (6). Hence, there is a great need for new substances that are effective and biocompatible.…”
