| Summary: | Exploration in endodontic material and procedure had been made to maximise
the elimination of the microorganisms in the root canal system to improve the
treatment success rate. Physicochemical and antibacterial properties are important in
producing a novel endodontic sealer. Antibiotic resistance can cause a global health
crisis if we use them inappropriately hence alternative is needed. Piper betle (PB) is
one possible medicinal herb to be used for its effective antibacterial properties against
Enterococcus faecalis (E. faecalis). Therefore, this study aims to investigate
physicochemical properties (pH and solubility), cytotoxicity, and antibacterial effects
of ethanolic extract of PB in combination with AH Plus (AH) and BioRoot RCS (BR)
and sealers alone. Four tested materials were used; AH; PB and AH plus (PBAH); BR;
and PB and BioRoot RCS (PBBR). pH testing was conducted for fresh and set sample
for a period from immediate up to 4 weeks. Solubility test was in alignment with the
International Standards Organization (ISO) method. At 24, 48, and 72 hours, MTT
assay on HPdLF was performed to measure the cytotoxicity. Antibacterial effect was
evaluated with modified direct contact test (MDCT) against E. faecalis at fresh, day-
1-set and day-7-set state of the tested materials. Data were analysed with SPSS version
25 with Tukey’s post-test at the level of significance of P = 0.05. In fresh state, PB
increase the alkalinity of AH at significant level (P = 0.000) after 2 hours. BR and
PBBR demonstrated significantly high (P = 0.000) alkaline value at all time points,
without significant difference with presence of PB. For set sample, PB decrease the
pH value of BR while increase the pH value of AH. PBBR showed significant reduction in solubility as compared to BR, AH and PBAH showed no significant
difference. Besides, PBAH showed significant decrease in cytotoxicity at 48 hours as
compared to AH (45.20%, 18.85%). PB reduce the antibacterial effect of BR at all
times at significant level (P = 0.000, 0.014, 0.032). Conclusion, PBAH has higher pH
value than AH at fresh state, while PBBR has lower pH value than BR when set. PBBR
has significant lower solubility than BR. PBAH has significant reduced cytotoxicity
as compared to AH on HPdLF at 48 hours. PBBR was cytotoxic to HPdLF at 24 and
48 hours. Both AH and PBAH exhibited antibacterial property against E. faecalis,
followed by BR and PBBR. In conclusion, PBAH is a potential enhanced root canal
sealer and may be further studied to fully elicit its profound properties. |
