BACKGROUND:Previous studies have demonstrated that nano-hydroxyapatite/polyamide 66 (nHA/PA66) composites as a root canal filing material possess the basic physical and chemical properties, have antibacterial properties against the infection of medulary cavity, and have no cytotoxicity. However, it is rarely reported as a direct pulp capping agent.
OBJECTIVE: To observe the histological reaction of nHA/PA66 composites as the pulp capping agent.
METHODS:The first and second molars from 12 Wistar rats were selected to prepare class I cavities by exposing the dental pulp. Then, these rats were randomized into three groups and subjected to dental pulp capping using nHA/PA66 composite, nHA and calcium hydroxide, respectively, folowed by filing with glass ionomer cement. At 7 and 30 days after filing, histological changes of odontoblasts and microvessels in the dental pulp were observed using ink perfusion method.
RESULTS AND CONCLUSION: At 7 days after filing, significant changes in dental pulp fibroblast proliferation, predentin thickening, dilation of blood vessels were observed in the nHA/PA66 group; only dental pulp fibroblast proliferation with no predentin thickening and dilation of blood vessels was found in the nHA group; in the calcium hydroxide group, the pulp tissues in the pulp chamber were mostly damaged, and obvious hyperplasia in dental pulp fibroblasts and certain inflammatory cel infiltration with vascular necrosis were observed. At 30 days after filing, predentin thickness was increased further, dental pulp fibroblasts proliferated, the number of odontoblasts increased, and dilation of blood vessels was observed in the nHA/PA66 group; predentin thickening and dilation of blood vessels were obviously visible in the nHA group; pulp necrosis was found on the pulp surface below the pitting pore, odontoblasts grew actively at the pulp junction, with no obvious thickening of the predentin, and there were dense vessels below the necrotic area. These findings indicate that the nHA/PA66 composite can induce the regeneration of dental pulp cels.

BACKGROUND:The mechanical properties of SonicFil ultrasonic resin are better than those of the traditional light-cured composite resin, but its effect on odontoblasts and dental pulp vessels is unclear.
OBJECTIVE:To study the effect of SonicFil ultrasonic resin on odontoblasts and dental pulp vessels of rats using histological methods.
METHODS:Twenty-five Wistar rats are selected for experiment. Ninety-six teeth from the first and second molars were selected and randomly divided into SonicFil ultrasound resin group and Filtek Z350 nano resin group with 48 teeth in each group. Experimental teeth in each group were equaly subdivided into 7 days group and 30 days group. Besides, randomly selected five teeth with no intervention served as normal control group. After anesthesia and disinfection, class I cavities on the occlusal surface of the maxilary first and second molars were prepared and filed with SonicFil ultrasound resin and Filtek Z350 nano resin group, respectively. The rats were sacrificed by ink perfusion method, and tooth specimens were taken to observe the changes of odontoblasts and pulp microvessels.
RESULTS AND CONCLUSION: At 7 days after filing, two groups had similar changes in the pulp presenting with mild inflammation. Besides, there were scattered inflammatory cels distributing in the cave pulp tissue, and in most of the specimens, odontoblasts arranged disorderly with little vacuoles and microvascular dilatation in the pulp. At 30 days after filing, in the SonicFil ultrasonic resin group, odontoblasts arranged orderly, inflammatory reaction and microvascular dilatation disappeared basicaly. In contrast, in the Filtek Z350 nano resin group, disordered odontoblasts decreased, inflammatory reaction weakened, as wel as microvascular dilatation became less. These results show that under the experimental condition, both of the SonicFil ultrasonic resin and Filtek SonicFil Z350 nano resin play certain roles in the formation of odontoblasts and dental pulp vessels, but over time al of these effects can automaticaly disappear.
