Effects of mineral trioxide aggregate and platelet-rich fibrin on histological results of direct pulp capping in dogs
Aim: This study aimed to compare the effects of mineral trioxide aggregate (MTA) and platelet-rich fibrin (PRF) on histological results of direct pulp capping (DPC) in dogs.
Methodology: In this animal study, 36 class V cavities were prepared in the incisors of adult healthy mixed-breed dogs. The teeth were then randomly divided into three groups. No material was placed in the control teeth. MTA and PRF were placed on the exposure site in groups 2 and 3, respectively. After 2 months, the teeth were extracted under general anesthesia and were histological analyzed regarding inflammation, calcified bridge formation and necrosis. Data were analyzed using non-parametric Kruskal-Wallis test. Pairwise comparisons were made using the Mann-Whitney U test.
Results: There are no statistically significant differences in terms of pulp inflammation, dentinal bridge formation and necrosis among the treatment groups capping with MTA and PRF. (P Value >0.05), however, PRF and MTA were the same in all parameters, these groups were both significantly superior to the control group.
Conclusion: Within the limitations of this study, PRF can be used for DPC as an alternative to MTA.
