“…Regenerative endodontic therapy (RET) has become a viable alternative in the treatment of immature teeth with pulpal necrosis as long as an adequate disinfection of the root canal system is guaranteed 2) . Most of RET clinical reports have used either triple antibiotic paste (TAP) [3][4][5][6][7] or pure calcium hydroxide (Ca(OH)2) paste [8][9][10][11] , as intracanal medicaments for this purpose.…”

TAP consisting of metronidazole, ciprofloxacin and minocycline, has been successfully used to disinfect the canals in RET, achieving closure of the apex and thickening of the dentinal walls [3][4][5][6][7] .

The antibacterial efficacy of intracanal medicaments for 2 and 7 days, in open apex root canals contaminated with Enterococcus faecalis biofilms was compared. One hundred and thirty-eight standardized uniradicular human roots were inoculated with E. faecalis. Colony forming units (CFU) were recorded before and after medication. Samples were divided in two (2/7 days), and subdivided (n=8/group): triple antibiotic paste (TAP); double antibiotic paste (DAP); dental base paste (DBP), consisting of calcium hydroxide, propylene glycol and calcium carbonate; DBP+0.2% chlorhexidine (CHX); DBP+0.2% cetrimide (CTR); DBP+0.2% CHX+0.2% CTR; 2.5% sodium hypochlorite (NaOCl); and distilled water. At both periods TAP, DAP, DBP+0.2% CHX, DBP+0.2% CTR and DBP+0.2% CHX+0.2% CTR exhibited no growth (NG) of E. faecalis. Distilled water and 2.5% NaOCl obtained the lowest CFU reduction. No growth with DBP was reached only at 7 days. CHX and/or CTR pastes were as effective as DAP and TAP. A 2-day period provided an effective disinfection.

“…Nosrat et al (2011) utilizaram uma mistura enriquecida de cálcio (CEM), uma substância que tem características de selamento e biocompatibilidade semelhantes ao MTA, é capaz de promover a formação de hidroxiapatita, induzir diferenciação de células-tronco e induzir a formação de tecido mineralizado (Asgary et al, 2009 (Lovelace et al, 2011). Esta descoberta foi muito importante, pois os protocolos de tratamento previamente usados na terapia endodôntica regenerativa tinham como objetivo a máxima desinfecção sem considerar o impacto delas sobre as células tronco .…”

Oliveira AP. Influence of intracanal medications used in regenerative endodontic procedures on survival of apical papilla cells in vitro [thesis]. São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2014. Versão Corrigida.Regenerative Endodontic procedures have provided changes in treatment of patients with immature teeth and apical periodontitis enabling full root development and lower incidence of dental fracture. Intracanal dressings are used for disinfection; however, their effect on apical papilla cells is poorly elucidated. Additionally, the effect of these substances on cells previously subjected to proinflammatory condition is still unknown. The aim of this study was to evaluate the cytotoxicity of intracanal dressings used in Endodontics regenerative procedures on cultured human apical papilla cells at physiologic and activated condition. Cell culture was established from the apical papilla removed from an extracted immature third molar. The substances studied were triple antibiotic modified paste: ciprofloxacin, metronidazole and cephalosporin (1:1:1); CFC: ciprofloxacin, metronidazole and calcium hydroxide (1:1:2) and modified CFC: ciprofloxacin , metronidazole and calcium hydroxide (2:2:1). Part of the cells was stimulated previously with lipotheichoic acid (LTA) of Enterococcus faecalis por 7 days. Once plated, cells were exposed to increasing concentration of the medications for 1, 3, 5 and 7 days. Cell viability was evaluated by means of 3-bromide (4.5-dimetiliazol-2-yl) -2.5-difeniltetraze (MTT) and Nitric Oxide (NO) release was assessed by the Griess method. The statistical analysis was done through analysis of variance with 1 criteria (ANOVA) followed by Tukey test with 5% of significance level. Modified CFC was the medication that demonstrated the less cytotoxic effect on cell viabilityat the experimental periods studied while CFC promoted significant decrease on cell viability specially after 7 days of contact. The modified triple antibiotic paste resulted in important alteration of cell viability being considered the most citotoxic. Cellular activation by LTA resulted in increased levels of mitochondrial activity for all medications being more evident at the longer experimental periods. Cellular activation also contributed to higher levels of nitric oxide release. In conclusion, the cytotoxic effect of the tested medications is dependent on concentration, time of contact and cellular condition, being the triple antibiotic modified paste the most cytotoxic in high concentrations leading clinically in the decreased of the cells viability of the apical papilla, decreasing the success of regenerative procedures.
