Inhibitory effect of sPDMA@ICG NPs with laser irradiation on the alveolar bone resorption in periodontitis rats. a Cross-sectional and b three-dimensional micro-CT images of the alveolar bones in the control rats (negative and positive) and the rats receiving the treatments of sPDMA, free ICG, sPDMA@ICG NPs with and without laser irradiation. c CEJ-ABC distance on the buccal and palatal sides and d BV/TV calculated from micro-CT results. * and **indicate P < 0.05 and P < 0.01 compared separately to the control ( +); ^##indicates p < 0.01 for comparison between two groups
