Preliminary Evaluation of BMP-2 Expression and Histological Characteristics During Apexification with Calcium Hydroxide and Mineral Trioxide Aggregate

Early carious lesions induce odontoblast stimulation in tertiary dentine formation even before the lesion reaches the dentine. The most used material for these procedures was calcium hydroxide, which was recently replaced by Mineral Trioxide Aggregate (MTA).The purpose of our study was to assess the histological characteristics of tertiary dentine induced by these materials in permanent molar teeth.We used 23 molars scheduled for extraction due to orthodontic reasons, in patients of 17-24 years of age. In a time interval of 4-8 weeks prior to extraction, occlusal cavities were prepared and filled with MTA or calcium hydroxide and glass ionomer cement.In teeth filled with MTA we noticed an early development of tertiary dentin layer, with a tubular structure, similar to secondary dentine. In the case of calcium hydroxide, the process of new dentine deposition was delayed and diffuse calcification, with formation of pulp stones was noticed.MTA proved to be superior to calcium hydroxide in inducing tertiary dentine formation, which appeared early after treatment. In time the differences in the amount of tertiary dentine between these materials are reduced, but there is a tendency of diffuse mineralization induced by calcium hydroxide.

Methods Of Treatment

The article presents the results of using a material based on the mineral trioxide unit “Bio-Dent”for the indirect coating of the pulp. It was found that there were no complaints from the use of domestic Portland cement both in the near term (98.8%) and inthe long term after treatment in comparison with materials based on calcium hydroxide (72.5%). Stabilization of the pulp electroexcitability indicators at the level of 10 mkA was noted with the use of the material based on MTA “Bio-Dent”as a medical liner for indirect pulp covering.Keywords: dental pulp,indirect pulp coating, calcium hydroxide, mineral trioxide aggregate, pulp electroexcitability.

The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 ?C. Mineral trioxide aggregate, bioactive dentin substitute or calcium-hydroxide paste were used as pulp capping materials. Cavities were restored with a light-cured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calcium-hydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5?C.

Single Visit

In this study, 120 teeth having periradicular pathosis were treated with single visit root canal treatment and then obturated with either calcium hydroxide containing sealer or mineral trioxide aggregate based sealer. The healing of periradicular pathosis was examined at 3, 6, and 12 months by clinical and radiological evaluation. Collected data were analyzed with standard statistical methods by using SPSS version- 20. The results showed that at 3 and 6 months, the differences between calcium hydroxide containing sealer or mineral trioxide aggregate based sealer were not statistically significant. However, the healing capability of periapical radiolucency at 12 months between two groups was statistically significant (P=0.03). The final outcome of the clinical and radiological investigation showed successful results of 96.6% and 98.1% in calcium hydroxide and mineral trioxide aggregate group, respectively. In conclusion, both calcium hydroxide and mineral trioxide aggregate based sealers are almost equally effective in single visit root canal therapy for the management of periradicular pathosis.

Microbiological Parameters

Background: Streptococcus mutans play an important role in occurrence of dental caries objective: to compare the clinical and microbiological antibacterial outcomes of Mineral trioxide aggregate (MTA) and Calcium hydroxide cement Ca(OH)2. Methodology: 20 primary molars in 10 children with year’s 5-9 y .For each child one tooth was treated with Ca(OH)2 and the other with MTA. Finally, all the cavities were restored using compomer restorative material, and then microbiological parameters were recorded. Results: MTA treated teeth did not show any clinical sign or symptoms of failure. While three teeth treated with Ca(OH)2 were excluded because of necrosis. Changes in color and consistency of dentin were nearly the same for both groups. Microbiological evaluation showed a decrease in the count of Str. mutans with calcium hydroxide and complete killing of bacteria with MTA. Conclusion: The treatment showed satisfactory results of MTA as it was more potent inhibitor of bacterial-growth than Ca(OH)2
