Comparative investigation of clinical/radiographical signs of mineral trioxide aggregate and formocresol on pulpotomized primary molars

Abstract

The objectives of this study were (1) to evaluate clinically and radiographically the effects of mineral trioxide aggregate (MTA) as a pulp dressing after coronal pulp amputation (pulpotomy) in primary molars, (2) to compare the effects of MTA and formocresol in pulpotomized primary teeth. Sixty primary mandibular molars of thirty healthy children aged between 5-8 years were treated by conventional pulpotomy technique. The teeth on the right side are assigned to MTA (Group A) and the left side for the Formocresol (Group B). The children were examined clinically and radiographically every 6 months over a period of 36 months. Results of present study revealed that both MTA and Formocresol has the same effect on the first as well as second primary molars, with chi-square value being 1.1483 (P ≥ 0.05). None of the teeth in either group showed any clinical pathology, showing 100% success rate but radiographically formocresol group showed one case of internal resorption that was regarded as failure in the present study. MTA seems to be more promising predictable with positive response in vital pulp therapy in future than formocresol pulpotomy except for the cost factor.

Asymmetrical root resorption in primary mandibular molars: Prevalence and determinants factors

“…MTA appears to be superior to formocresol and could serve as a suitable replacement, but generally costs more than formocresol. [17][18][19] Although the use of formocresol has been questioned, a recent study showed that the clinical and radiographic success rates for the formocresol at 12 months were 97% and 87%, respectively. These rates were higher than alternatives methods for pulpotomy (diode laser and ferric sulfate).…”

Odontogenic effects of a fast-setting calcium-silicate cement containing zirconium oxide

“…The procedure preserves the vitality of the remaining pulp and helps retain the tooth in a desirable state until normal exfoliation occurs. For these purpose, mineral trioxide aggregate (MTA) has been successfully used as an alternative to formocresol [2][3][4][5][6][7][8][9][10][11] and calcium hydroxide 12,13) due to its favorable physical and biological properties. It is composed mainly of Portland cement, with bismuth oxide included as a radiopacifier.…”

Efeitos do Laser de Baixa Intensidade em pulpotomias de dentes decíduos humanos

“…A manutenção da dentição decídua, sem perdas prematuras, preserva a integridade dos arcos e as funções do sistema estomatognático, previne hábitos deletérios e assegura o desenvolvimento do crescimento facial normal (CAICEDO et al, 2006;FUKS, 2008;SUBRAMANIAM et al, 2009;BLANCHARD;HUGAR;DESHPANDE, 2010;COLL, 2010;GODHI;SOOD;SHARMA, 2011;HUTH et al, 2012).…”

“…Como no presente estudo, este tipo de monitoramento a partir de exames clínicos e radiográficos longitudinais é consolidado e aceito na literatura (AGAMY et al, 2004;NEAMATOLLAHI;TAJIK, 2006;CASTRO;PINTO, 2006;AEINEHCHI et al, 2007;MORETTI et al, 2008;ALAÇAM et al, 2009;FORNETTI et al, 2009;SAKAI et al, 2009;HUGAR;DESHPANDE, 2010;ERDEM et al, 2011;MALEKAFZALI;SHEKARCHI;ASGARY, 2011;JAYANTHI, 2011;ODABAS et al, 2011;HUTH et al, 2012;RUBY et al, 2013;FERNÁNDEZ et al, in press).…”

“…Outras técnicas incluem a aplicação do algodão estéril embebido em soro fisiológico, água oxigenada, hipoclorito de sódio, soluções anestésicas, clorexidina, epinefrina ou sulfato férrico (TUNÇ et al, 2006;YAMAN et al, 2012). Se a hemorragia pulpar não cessa ou há formação de um coágulo, entre o material e o remanescente pulpar, ocorre uma resposta inflamatória crônica que prejudica o processo de reparo (ODABAS et al, 2011;YAMAN et al, 2012 FUKS, 2002;AGAMY et al, 2004;FARSI et al, 2005;FUKS, 2005;HUTH et al, 2005;LIU, 2006;PENG et al, 2006;TUNÇ et al, 2006;FUKS, 2008;MORETTI et al, 2008, TOOMARIAN et al, 2008, ODABAS et al, 2009COLL, 2010;HUGAR;DESHPANDE, 2010;BLANCHARD; GOLPAYEGANI; ANSARI; SIMANCAS-PALLARES; DÍAZ-CABALLERO; LUNA- RICARDO, 2010;TADAYON, 2010;ZEALAND et al, 2010;GISOURE, 2011;VOSTATEK et al, 2011;HUTH et al, 2012;RUBY et al, 2013). Em nosso estudo optamos pelo emprego do formocresol diluído a 1/5, pois vários estudos comprovaram que a solução de FC diluída a 1/5 é tão efetiva quanto a concentrada original, possuindo as mesmas propriedades bactericidas e de fixação tecidual, com o diferencial de ser menos tóxica e agressiva aos tecidos pulpares e periapicais (MORAWA et al, 1975;ABDO et al, 1979;FUKS, 2002;PAPAGIAMOULIS, 2006;HANEY, 2007;FUKS, 2008;HAGHGOO;…”
