ABSTRACT

Objective:

To assess the effect of application of Biodentine (BD), Photobiomodulation (PBM) using 810 nm diode laser and both on the proliferation and odontogenic differentiation of human dental pulp stem cells (HDPSCs). Material and

Methods:

HDPSCs were collected, isolated, and characterized and then divided into six groups groups 1, control; groups 2, biodentine (BD); group 3, irradiation at 1 J/cm 2 of 810-nm diode laser; group 4, irradiation at 1 J/cm 2 and culture with BD; group 5, irradiation at 2 J/cm 2, and group 6, irradiation at 2 J/cm 2 and culture with BD. Viability assay was measured through MTT assay and Alkaline phosphatase (ALP) enzyme activity and mRNA levels of RUNX2, collagen 1 (Col-1) and BMP2 were also assessed.

Results:

Photobiomodulation at 1 and 2 J/cm 2 combined with biodentine significantly promoted HDPSCs proliferation (in MTT assay results) and odontogenic differentiation (through the gene expression of RUNX2, Col-1 and BMP2 levels (p < 0.05).

Conclusion:

Photobiomodulation at 2 J/cm 2 combined with biodentine enhanced proliferation and odontogenic differentiation of cultured HDPSCs and thus could further be beneficial for dentin regeneration (AU)
RESUMO

Objetivo:

Avaliar o efeito da aplicação de Biodentina (BD), Fotobiomodulação (PBM) usando diodo de laser de 810 nm e ambos na proliferação e diferenciação odontogênica de células tronco cultivadas da polpa dental (HDPSCs). Material e

Métodos:

HDPSCs foram coletadas, isoladas, caracterizadas e então divididas em seis grupos grupo 1, controle; grupo 2, biodentina (BD); grupo 3, irradiação com diodo de laser a 1 J/cm2 de 810- nm; grupo 4, irradiação a 1 J/cm 2 e cultivo com BD; grupo 5, irradiação a 2 J/cm2, e grupo 6, irradiação a 2 J/cm2 e cultivo com BD. A viabilidade foi mensurada através do teste MTT e a atividade da enzima Fosfatase alcalina (ALP), e níveis de RNAm de RUNX2, de colágeno 1 (Col-1) e de BMP2 foram também mensurados.

Resultados:

Fotobiomodulação a 1 e 2 J/cm 2 combinada com biodentina promoveu significativa proliferação de HDPSCs (nos resultados do teste MTT) e diferenciação odontogênica (através da expressão genética dos níveis de RUNX2, Col-1 e BMP2 (p < 0.05)).

Conclusão:

Fotobiomodulação a 2 J/cm2 combinada com biodentina aumentou a proliferação e diferenciação odontogênica de HDPSCs cultivadas e dessa forma poderia ser benéfica para a regeneração dentinária. (AU)
