Question

Berber, Gomes et al (2006) studied the efficacy of various concentrations of NaOCL and instrumentation techniques in reducing E. faecalis within root canals and dentinal tubules. What did they find regarding the effectiveness of different concentrations of NaOCL?

a) Higher concentrations of NaOCL were more effective in reducing E. faecalis
b) Lower concentrations of NaOCL were more effective in reducing E. faecalis
c) Concentration of NaOCL did not significantly affect reduction of E. faecalis
d) E. faecalis was completely resistant to NaOCL treatment

Answer 1

Berber, Gomes et al. (2006) discovered that higher concentrations of NaOCL were more effective at reducing E. faecalis within root canals and dentinal tubules.

Step-by-step explanation:

Berber, Gomes et al. (2006) researched the impact of various concentrations of sodium hypochlorite (NaOCL) on reducing Enterococcus faecalis in root canals and dentinal tubules. According to their findings, higher concentrations of NaOCL were more effective in mitigating the bacteria than lower concentrations. This means that while NaOCL, in general, is a potent antimicrobial agent used in endodontic therapy, its efficacy in eliminating E. faecalis increases with the concentration used. This result aligns with the understanding that different chemical agents have varied levels of disinfectant effectiveness, with some being stronger or more effective than others.

The study conducted by Berber, Gomes et al (2006) examined the effectiveness of different concentrations of NaOCL in reducing E. faecalis within root canals and dentinal tubules. The researchers found that higher concentrations of NaOCL were more effective in reducing E. faecalis, suggesting that higher concentrations of NaOCL have stronger antimicrobial properties.
