Moringa oleifera Leaves and Their Effects on Hypersensitivity and Biomimetic Cementum Tissue Formation

A new study published in the Scientific Reports suggests that Moringa oleifera leaves are effective for hypersensitivity and the formation of biomimetic cementum tissue.

Study Overview

A study was conducted to evaluate the biomimetic remineralization capabilities of Moringa oleifera leaves (MOL) extract on coronal dentin and acellular cementum. Two different concentrations (50 and 200 mg/ml) of MOL extract loaded in plain varnish (M1 and M2 groups respectively) were compared to fluoride varnish (FL group) and native surface (C group).

• Eighty sound premolar teeth were collected.
• Forty teeth (10 teeth in each group) were used for coronal dentin testing.
• The other forty (10 teeth in each group) were used for acellular cementum testing.
• Teeth in M1, M2, and FL groups were etched for 30 seconds and then received the specific varnish treatment.

Methodology

All samples were immersed in artificial saliva for 14 days and then collected, dried, and examined by scanning electron microscopy and energy dispersive X-ray spectroscopy (EDX).

Results

Histologically, the FL group showed mineral deposition as discrete vesicular granules of various sizes on the surface of both coronal dentin and acellular cementum. Mineral deposition only occurred on some DTs openings while opened tubules remained. The surface of the acellular cementum revealed regular grooves, micro-fissures, and cracks.

In the M1 and M2 groups, mineral deposition appeared as a homogenous continuous layer on coronal dentin and acellular cementum. Only a few DTs and cementum fissures were not filled completely. In L.S. sections of the coronal one-third, the DTs appeared almost sealed with varying lengths of mineral deposition. EDX results statistical analysis showed that the M2 group had the highest phosphate ions (P−) and calcium ions (Ca+2) at%.

Conclusion

MOL has an extraordinary effect on the remineralization of coronal dentin and acellular cementum. It would have a promising ability to control dentinal hypersensitivity and formation of biomimetic cementum tissue.
