Pulpal Response to Nano Hydroxyapatite, Mineral Trioxide Aggregate and Calcium Hydroxide when Used as a Direct Pulp Capping Agent: An in Vivo study

Nano hydroxyapatite (Nano-HA) and Mineral Trioxide Aggregate (MTA) because of its better qualities can be used as an alternative to calcium hydroxide in direct pulp capping procedures. The aim of the study was to compare the response of exposed human pulp to Nano-HA, Mineral Trioxide Aggregate and calcium hydroxide. Study design: The study was done on 30 premolars, ranging from patients between 11-15 years. Intentional pulp capping was done using one of the experimental materials. The extracted teeth were then subjected to staining procedure and evaluated for dentin bridge and pulpal response after 15 and 30 days. Intragroup comparisons of the observed values were analyzed using Chi-square test. Results: Nano-HA and MTA produced continuous dentin bridges. Dentin bridge that was formed in MTA group had regular pattern of dentinal tubules but no tubules were seen in the nano-HA group. Dentin bridge was not observed in Dycal group for the 15 days period in majority of the sample and by 30 days dentin bridge was observed that were both continuous and interrupted in equal number of samples. The initial inflammatory response and necrosis was more with Nano-HA and calcium hydroxide which reduced with time. Conclusion: MTA showed no inflammatory changes in majority of the samples in both the study periods. Necrosis was least observed in MTA group followed by Nano-HA. Vascularity increased in Nano-HA group in the initial periods which reduced with increasing time. Based on the ability of nano-HA to produce complete dentinal bridges, favorable cellular and vascular response, the material could be considered as an substitute and could be tried used as a direct pulp capping agent.

The aim was mainly to determine the correlation between the type of pulp capping method and the material of choice in this study. Pulp capping in the carious teeth has been considered as unpredictable and they mainly have a lesser success rate. The pulp capping can be mainly done in two methods; they are direct and indirect pulp capping which can be mainly done with the help of different materials of choice like calcium hydroxide,MTA etc. The study was conducted in Saveetha Dental College . The data collection has been done from the department of Conservative dentistry and Endodontics for patients undergoing pulp capping treatment. A total sample data of 140 patients were obtained for a period of nine months ( June 2019 – April 2020.). Statistical analysis was done by using chi-square test with SPSS software version 23. The results were obtained and tabulated, the type of pulp capping method were 67% of indirect pulp capping and 33% of direct pulp capping method in which 81% of calcium hydroxide, 8% of MTA and 11% of RMGIC was used as the materials of choice. Among which indirect pulp capping method was most commonly used than the direct pulp capping method with calcium hydroxide as the material of choice for the treatment (p < 0.05 which is statistically significant). The pulpal exposure was mainly due to the dental caries and mechanical preparation of the tooth. Within the limits of the present study, the most common type of the pulp exposure was due to the dental caries and mechanical exposure during the cavity preparation of the tooth and the most common method of pulp capping was the indirect method with calcium hydroxide (CaOH) as the most common material of choice.

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.

Aim: To evaluate the clinical success of Calcium Hydroxide (CH), Mineral trioxide aggregate (MTA) and Biodentine as pulp capping materials for Direct pulp capping in carious molars. Materials and Methods: Thirty-six molars of thirty-six patients with deep caries lesions, diagnosed with reversible pulpitis were subjected to direct pulp capping treatment. They were randomly divided into three groups, Biodentine (12 teeth) or MTA group (12 teeth) or CH group (12teeth). Simple randomization of three was employed to allocate the treatment materials. Patients were recalled at one, three and six months to evaluate the clinical success of the treatment outcome. Results: In clinical trial/study, the pulp capping materials gave different success rate, 91.67% success in the Biodentine group, 75% success in the MTA group and 41.67% success in Calcium Hydroxide group. Conclusion: In our study the materials tested at 1 month, 3 month and 6-month follow-up, Calcium Silicate materials are better than calcium hydroxide and comparably Biodentine is better than MTA for Direct pulp capping. Clinical Significance: The findings of this clinical trial could promote the reliability of pulp capping materials for treatment of deep carious lesions by conservative approach rather than opting endodontic management.

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.
