Success of mineral trioxide aggregate in pulpotomized primary molars

Abstract

The aim of the present study was to compare, clinically and radiographically, the mineral trioxide aggregate (MTA) to formocresol (FC) when used as medicaments in pulpotomized vital human primary molars. METHODS: The sample consisted of 120 primary molars, all teeth were treated with the same conventional pulpotomy technique. Sixty molars received FC and 60 received MTA throughout a random selection technique. RESULTS: At the end of 24-month evaluation period, 74 molars (36 FC, 38 MTA) were available for clinical and radiographic evaluation. None of the MTA treated teeth showed any clinical or radiographic pathology, while the FC group showed a success rate of 86.8% radiographically and 98.6% clinically. The difference between the two groups i n the radiographic outcomes was statistically significant. It was concluded that MTA treated molars demonstrated significantly greater success. MTA seems to be a suitable replacement for formocresol in pulpotomized primary teeth.

Comparison of mineral trioxide aggregate and formocresol as pulp medicaments for pulpotomies in primary molars

“…Farsi et al 21 reported a signifi cant dif ference between the two groups (MTA and FC pulpotomies in primary molars) after 24 months of radiographic evalu ation, but the results of this study were study, MTA showed a higher (though not statistically significant) long-term clini cal and radiographic success rate than formocresol. 22 In spite of the similarity of success rates of FC and MTA in this study, one clinical disadvantage of MTA compared to FC is the fact that the tooth has to be restored after 24 hours to allow time for the MTA to set.…”

“…MTA has been proposed as a poten tial medicament for various pulpal pro cedures in permanent teeth, eg pulp capping, apexification, repair of root perforations etc, and has had successful results. [20][21][22][23][24] With due attention to the bio compatibility and biological seal of MTA, several studies have been performed to evaluate its efficacy as a pulpotomy medicament in primary molars. [8][9][10]13,21 Eidelman et al 8 showed MTA pulpoto mies in primary molars that were followed up for 6-30 months were clinically and radiographically successful.…”

In the studies of Naik 9 and Maroto et al, 13 the clinical and radiographic evaluations were done at six months after pulpotomy in pri mary molars.…”

“…19,20 Lately, MTA has been used as a pulpotomy medica ment in primary molars and it was found to be a successful material. 13,21,22 The objective of this study was to clinically and radiographically evalu ate the effects of tooth-coloured (white) MTA as a pulp dressing agent in pulpot omised lower second primary molars for 24 months and compare them to those of FC.…”

Pulpotomy of human primary molars with MTA and Portland cement: a randomised controlled trial

“…[3][4][5][6][7] Medicaments applied to radicular pulp tissue after pulpotomy have included formocresol, 1,3,4 ferric sulphate, 3,4 calcium hydroxide 4 and mineral trioxide aggregate (MTA). 1,[8][9][10][11][12][13][14] Objective This study compared the clinical and radiographic effectiveness of mineral trioxide aggregate (MTA) and Portland cement (PC) as pulp dressing agents in carious primary teeth. Methodology Thirty carious primary mandibular molars of children aged 5-9 years old were randomly assigned to MTA or PC groups, and treated by a conventional pulpotomy technique.…”
