Comparing the Clinical, Radiographical and Histological Effects of Pulpotomy with Different Materials in Dogs’ Deciduous Teeth

Background and Aim: The aim of this study was to compare the effects ofdifferent pulpotomy materials in dogs’ deciduous teeth.Methods: In this experimental study, 56 premolar teeth in 5 mixed-breedIranian dogs of 6-8 weeks, were randomly divided into 10 groups. In thetreatment groups, formocresol, Gutta-percha, mineral trioxide aggregate(MTA), collagen, SHED, BMP2 and SHED + BMP2 were placed on thecanal orifice and restored by a zinc oxide eugenol (ZOE) and restorativeglass ionomer. After observing mobility in most teeth, periapicalradiography of the teeth was conducted under general anesthesia andall the teeth were extracted. The histologic samples were studied blindlyby the pathologist in terms of their inflammatory reaction and hard tissue formation. Finally, the data were analyzed by one-way ANOVA, Kruskal-Wallis, chi-square and least significant differences analysis with SPSS Ver.20 (α = 0.05).Results: The clinical symptoms and the radiographic symptoms showedno significant difference between the groups (P chi-square > 0.05). Therewas a significant difference between the mean of total inflammationindex (P one-way ANOVA=0.019), and the types of hard tissue formed(P-value = 0.001) between the studied groups.Conclusion: SHED+BMP2+Collagen showed the highest hard tissueformation and the least inflammation.
