Results of the study showed a significant difference in hard tissue bridge formation with ProRoot MTA, while RetroMTA performed better in terms of continuity, morphology, and inflammatory reaction. Although RetroMTA healed pulpal tissue faster, it seemed to be more of a reparative process compared to ProRoot MTA.
Traumatic human dental injuries involving the pulp might necessitate direct capping procedures. This clinical study aimed to analyse the histological outcomes using two different direct capping materials. Twenty patients with bilateral premolars, scheduled for orthodontic extraction, were selected. The teeth were treated either using ProRoot MTA or RetroMTA. All patients were recalled after 30 and 60 days for teeth extraction. The histopathologically stained specimens were blindly evaluated using hard tissue bridge formation, inflammatory reaction and pulpal findings criteria. Data were evaluated statistically. Results: After 60 days, only the parameter for hard tissue bridge formation showed significant difference in the ProRoot MTA group (p = 0.010), while both direct capping materials performed similarly regarding inflammatory pulp reaction and pulpal findings. Although, during the first 30 days, RetroMTA presented better results in terms of continuity, morphology, hard tissue bridge localisation, and extension/general state of the inflammatory reaction, the continuity was better at 60 days when ProRoot MTA was applied. Treatment with RetroMTA healed the pulpal tissue faster compared with ProRoot MTA but it seemed to be rather a reparative process.
