A clinical evaluation of mineral trioxide aggregate for root‐end closure of non‐vital immature permanent incisors in children‐a pilot study

Abstract

The aim of this pilot study was to evaluate the clinical efficacy of mineral trioxide aggregate (MTA) as an apexification material when used in non-vital immature permanent incisors in children. Fifteen children with a mean age of 11.7 years and 17 non-vital permanent incisors were ajudged suitable for inclusion. Standard endodontic procedures were followed and an apical plug of 3-4 mm was created by using MTA after a calcium hydroxide intracanal dressing had been applied for at least 1 week. Final obturation was completed by using thermoplastisized Gutta-Percha (Obtura II) at least 1 week following MTA placement. Subjects were reviewed clinically and radiographically at 3-month intervals. Mean follow-up time for MTA was 12.53 months (+/-2.94 SD). Of the total of 17 teeth treated, MTA placement was considered to be adequate in 13 teeth. The procedure showed clinical success in 94.1% of the cases, radiographic success was found to be 76.5% and in further three cases (17.6%) the outcome was considered to be uncertain. This is one of the very few studies that have reported the out coming of MTA as an apexification material in children with non-vital teeth and incomplete root development. However, larger clinical studies are required to evaluate the long-term success of this procedure.

Intracannal pain remission in child with amelogenesis imperfecta. Case report

“…The use of calcium hydroxide in the short term does not negatively affect tooth resistance 30 . In our case, X-rays after six months of treatment has shown significant decrease in periapical lesions, being in agreement with studies of Annamalai & Mungara 28 and Sarris et al 31 . However, the latter suggest broader clinical trials to evaluate long term success.…”

Cimentos biocerâmicos em endodontia: revisão de literatura

“…A maioria dos estudos buscou comparar as propriedades de cimentos endodônticos biocerâmicos com cimentos endodônticos convencionais e com o MTA, encontrando evidências consideráveis que apoiam esse material como padrão-ouro para vários procedimentos clínicos [35][36][37][38] . Um material ideal utilizado para reparo endodôntico deve ser biocompatível, radiopaco, antibacteriano, dimensionalmente estável, fácil de manipular, além disso, não deve ser afetado pela contaminação sanguínea 10 .…”

Evaluation of Portland cement insertion techniques for apical plug confection in teeth with open apex

“…In addition, a dark-colored gelatin was used to avoid direct visualization of the apex. Sarris et al 19 used wax to cover the apex in an in vitro study; however, they noted that the manufactured model was not similar to actual clinical conditions, as the wax represented a hard physical barrier to which MTA could certainly be condensed. Importantly, this barrier does not clinically exist and the material needs to be lightly pressed in place so as to prevent the overflow to periapical tissues.…”

“…21 Different techniques can be employed to manufacture an apical plug, with manual tools being properly used to insert and condense the material. MTA applicator is commonly used to this end; 13,19 but its thickness makes it difficult to insert the material into the apical portion, requiring the use of other thinner tools 19 to complement condensation. Despite its widespread use, the technique using this tool (Group II) achieved a 30% success rate.…”

“…The condensation of each increment of material may be performed by condensers, 15,23 gutta-percha cone, 17 paper cone 16,19,23 and file involved in cotton. 14 Ultrasound can be used as a complementary measure to condensation carried out with condensers.…”
