[Clinical effect of Nd:YAG laser combined with total glucosides of paeony for the treatment of erosive oral lichen planus].

Purpose: To investigate the clinical effect of Nd:YAG laser combined with total glucosides of paeony (TGP) taken orally for the treatment of erosive oral lichen planus (OLP).

Methods: Sixty patients who were diagnosed as erosive OLP with clinical symptoms were divided into experimental group (n=28) and control group (n=32) using a random number table. All patients received TGP while the patients in the experimental group were given Nd:YAG laser irradiation.

[Coculture of stem cells from the apical papilla and human umbilical vein endothelial cells enhances the angiogenic potential of dental pulp tissues].

Purpose: To observe the effect of coculture of stem cells from the apical papilla (SCAPs) and human umbilical vein endothelial cells (HUVECs) on the angiogenic potential of dental pulp tissues.

Methods: SCAPs were incubated in osteo/odontogenic, adipogenic, neurogenic induction medium and α-MEM medium, whose multilineage differentiation capacities were confirmed using alizarin red staining, oil red O staining and βIII-tubulin immunofluorescent staining. The tubular length, branching points number and junctional areas were detected after 3, 6, 9 h since cells were seeded onto matrigel, and the data was analyzed using SPSS 16.
