Abstract
Preservation of the vital pulp tissue is mandatory for completion of the root maturation. Management of infected pulp has a great dilemma in the modern dentistry, so the choice of the proper capping material is one of the main factors for success of the treatment.
This study was performed to evaluate the effect of pulpine mineral on root maturation for immature dog teeth with infected pulp after partial pulpotomy and compare the results with Mineral Trioxide Aggregate (MTA).
Materials and Methods
Forty- eight teeth were selected from four mongrel dogs and class V cavities were prepared and the pulp were exposed and left uncovered for one week to get infected. Samples were divided into 2 experimental groups according to the observation period (one month and three months), then each group had 4 subgroups according to the treatment done Gr.1 was pulpine mineral, Gr2. MTA, Gr.3 positive control, Gr4. Negative control.
Following the follow up period dogs were sacrificed, and the maxilla and the mandible were surgically removed and placed in 10% formalin.
Blocks containing a single tooth with its surrounding bone were obtained by sectioning the jaws with a sharp saw.
Samples were evaluated radiographically to detect the increase in the root length, root thickness and the reduction in the apical diameter. And after scarification they were evaluated histologically to detect the number of inflammatory cells as well as the score. And the dentine bridge thickness and continuity.
Results
Pulpine mineral had a very good result compared to MTA in terms of the increase in the root length, thickness, and the reduction of the apical foramen. Histologically, pulpine mineral showed better results than MTA regarding the dentin bridge formation with less inflammatory reaction.
This study concluded that pulpine mineral can be a suitable alternative to MTA in managing the infected pulp.
