Direct Capping

This study evaluated the biocompatibility of mineral trioxide aggregate (MTA) after direct capping of exposed pulp tissue in dog's teeth. Class I cavities were prepared in 26 teeth from 3 adult dogs. MTA was applied over the exposed pulp in 13 teeth and paste of calcium hydroxide plus distilled water (control) was applied in the remaining 13 teeth. After 90 days, the animals were killed; the maxilla and mandible were dissected and sectioned to obtain individual roots. The samples were processed histologically. The pulp and periapical response observed with the use of MTA was similar to that of calcium hydroxide paste. In all specimens, there was a dentin bridge obliterating the exposure, an intact odontoblastic layer, no inflammatory cells, normal connective pulp tissue, normal apical and periapical regions and no bone tissue changes. Similar to calcium hydroxide, MTA presented excellent response when used for direct pulp capping.

Pulp Capping

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.

Background: Cellular response of dental pulp to existing lesions, caused by infiltration of inflammatory cells that migrate from blood vessels to the site of injury. Macrophages are the cells that most appear when inflammation occurs. Treatment for maintaining pulp tissue vitality is called pulp capping. Calcium hydroxide as a pulp capping material has the ability to trigger the growth of dentin bridges or remineralization, but calcium hydroxide can induce migration and proliferation of inflammatory cells. Currently the field of dentistry is developing propolis as an alternative pulp capping material. That is because propolis has anti-inflammatory properties. Objective: To analyze the effect of the combination of calcium hydroxide-propolis on the number of macrophage cells in the teeth of wistar rats with pulp perforation. Method: This study used 30 samples of Wistar rats which were preparated until perforation and then divided into 3 groups. The first group continued with filling with cention, the second group continued with application of calcium hydroxide and filled with cention, and the third group continued with the application of combination of calcium hydroxide and propolis and then being filledwithcention. Macrophage cell is calculated histopathologically by using compound light microscope on the 3rd day with 400x magnification. Results: The Kruskal-Wallis test results showed significant differences in macrophages after the combination of calcium hydroxide and propolis (p = 0,000). The combined application of calcium hydroxide and propolis showed higher macrophages than the application of calcium hydroxide and the control group. Conclusion: Application of calcium hydroxide - propolis combination was proven increase the number of macrophage cells in Wistar Rats (Rattus Norvegicus) with pulp perforation

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.

OBJECTIVE: To investigate the pulpal response to direct pulp capping in healthy human teeth with Portland cement (PC) as against mineral trioxide aggregate (MTA) as control.METHODS: Forty healthy human third molars indicated for extraction were randomly divided into two groups: PC and MTA. The teeth had iatrogenic pulp exposed and direct pulp capping with PC or MTA. After 1, 7, 14 and 21 days, the teeth were extracted and prepared for histological examination and bacterial detection. The Mann-Whitney test was applied for statistical analysis (p < 0.05).RESULTS: The MTA presented higher capacity to form of dentin bridges at 14- and 21-day intervals (p < 0.05). However, no significant statistical difference was found between the groups at all evaluated intervals (p > 0.05) for the response variables of inflammatory cells, soft tissue organization and bacterial staining.CONCLUSION: The PC has a biocompatibility equivalent to the MTA but with a lower capacity to form of dentin bridges. Therefore, MTA should be the material of choice for direct pulp capping.
