AIMS
This study aims to assess the synergistic effect of utilizing a bioceramic sealer, NeoPutty, with photobiomodulation (PBM) on dental pulp stem cells (DPSCs) for odontogenesis.
MATERIALS AND METHODS
Dental pulp stem cells were collected from 10 premolars extracted from healthy individuals. Dental pulp stem cells were characterized using an inverted-phase microscope to detect cell shape and flow cytometry to detect stem cell-specific surface antigens. Three experimental groups were examined: the NP group, the PBM group, and the combined NP and PBM group. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) experiment was conducted to assess the viability of DPSCs. The odontogenic differentiation potential was analyzed using Alizarin red staining, RT-qPCR analysis of odontogenic genes DMP-1, DSPP, and alkaline phosphatase (ALP), and western blot analysis for detecting BMP-2 and RUNX-2 protein expression. An analysis of variance (ANOVA) followed by a -test was employed to examine and compare the mean values of the results.
RESULTS
The study showed a notable rise in cell viability when NP and PBM were used together. Odontogenic gene expression and the protein expression of BMP-2 and RUNX-2 were notably increased in the combined group. The combined effect of NeoPutty and PBM was significant in enhancing the odontogenic differentiation capability of DPSCs.
CONCLUSION
The synergistic effect of NeoPutty and PBM produced the most positive effect on the cytocompatibility and odontogenic differentiation potential of DPSCs.

目的
本研究旨在评估利用生物陶瓷密封剂 NeoPutty 与光生物调节(PBM)联合作用于牙髓干细胞(DPSCs)对牙发生的协同效应。
材料与方法
从 10 颗来自健康个体的前磨牙中提取牙髓干细胞。使用倒置相差显微镜检测细胞形态,流式细胞术检测干细胞特异性表面抗原对牙髓干细胞进行鉴定。研究了三组实验:NP 组、PBM 组和 NP 和 PBM 联合组。通过 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴盐(MTT)实验评估 DPSCs 的活力。通过茜素红染色、牙源性基因 DMP-1、DSPP 和碱性磷酸酶(ALP)的 RT-qPCR 分析以及 BMP-2 和 RUNX-2 蛋白表达的 Western blot 分析来分析牙向分化潜能。采用方差分析(ANOVA)和 t 检验对结果的均值进行检验和比较。
结果
研究表明,NP 和 PBM 联合使用时细胞活力显著升高。联合组牙源性基因表达和 BMP-2、RUNX-2 蛋白表达明显增加。NeoPutty 和 PBM 的协同作用显著增强了 DPSCs 的牙向分化能力。
结论
NeoPutty 和 PBM 的协同作用对 DPSCs 的细胞相容性和牙向分化潜能产生了最积极的影响。
临床意义
创造创新的再生治疗方法,以高效和持久地修复受损的牙齿组织。
