The use of beta-tricalcium phosphate, white MTA, white Portland cement and calcium hydroxide for direct pulp capping of primary pig teeth

Background : Perforation in normal pulp could be happened anytime. In sterile condition, direct pulp capping was the right therapy to maintain the vitality and pulp function. Direct pulp capping agent must contact with the pulp tissue. Generally, body had an immunologic respond with foreign body that contact with tissue. The respond could be inflammatory reaction. The used direct pulp capping agents were calcium hydroxide, and Mineral Trioxide Aggregate (MTA) which known as better agent but relatively expensive and difficult to obtain. So that, the alternative of MTA, Portland cement which was the same essential of MTA, was being developed. The aim of this study, to analized inflammatory reaction of the pulp tissue with direct pulpcapping agents calcium hydroxide, MTA, and Portland cement.Methods: Free caries M. Nemestrina’s posterior teeth were prepared to formpin point perforations on buccal surface of the crowns. The teeth were appliedwith one of the three capping agents. Teeth were filled and extracted. Theextracted teeth were proceed into histopatological preparation slides to evaluatethe inflammatic reaction.Results: The result showed no statistically significant differences of pulp inflammatory reaction between calcium hydroxide, MTA and Portland cement in7, 14, 42, and 90 days.Conclusion: The inflammatory reaction of pulp tissue of the three pulp cappingagent (calcium hydroxide, MTA, and PC) were insignificant different.

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.

Reparative Dentin Formation

This study was performed to examine whether calcium silicate could induce reparative dentin formation without eliciting any adverse effect in direct pulp capping of premolar teeth. Twenty participants who need extraction of their 4 healthy permanent premolar teeth for orthodontic reasons were included in this study. Following the surgical procedure, the exposed pulp tissue was treated either with calcium silicate or covered with calcium hydroxide paste. On day 3, 7, 14 and 28, the experimental teeth was extracted and examined using light microscopy and histometric analysis to observe the inflammatory changes and the amount of reparative dentin formation. The results showed that in the calcium silicate treated teeth, substantial amounts of dentine-like tissue was formed on day 14 and mostly located on the exposure site. It was also observed in the calcium hydroxide treated teeth but dentin-like tissue located at a distance from the exposure site. The total amount of reparative dentine formed in the calcium silicate-treated teeth was significantly higher (p<0.005) than in the calcium hydroxide-treated specimens. In conclusion that the calcium silicate indices pulpal wound healing and reparative formation in the exposed teeth without affecting the normal function of the remaining pulp.
