Fourteen root perforations were performed for microscopic evaluation of the repair of interradicular tissue in dogs' teeth. These perforations were accomplished at low-speed with a STP 58 bur at the cervical third of the mesial root toward the furcation under irrigation with saline solution, followed by immediate sealing with ProRoot MTA, MTA-Angelus and white Portland cement. The dogs were killed after 90 days, revealing good results. The Kruskal-Wallis test did not demonstrate any statistically significant difference. It was concluded that the three materials showed good sealing in mineralized tissue, with complete closure, and they were free of inflammation in most teeth.

We aimed to analyze particle size of a new endodontic biomaterial [calcium enriched mixture (CEM) cement], white mineral trioxide aggregate (WMTA), and white Portland cement (WPC). The analyses were performed twice. For each analysis, 0.05 mg of test material was experimented using particle size analyzer model HELOS and disperser CUVETTE. Distribution of particles in different ranges in addition to cumulative percentage and the mean of particle size were calculated. Data were analyzed using oneway ANOVA, Tukey and Chi-square tests. No significant differences were observed between the cumulative percentages of particle size in test materials. However, means of particle size were significantly different between WPC and WMTA (P<0.001). Among different investigated ranges of particle size distribution, the range of ≤30μm showed significant difference between three tested materials (P<0.05). The largest distribution of smallest range of particles was related to CEM cement. The sealing ability and satisfying physical properties of this novel biomaterial are due to a high percentage of small partcles in CEM cement.

Background: The initial inflammatory reaction of pulp capping materials on the dental pulp has an intimate relation in promoting the future cellular differentiation and biomaterial mineralisation. So, analysis of immediate pulpal tissue reaction in vivo, is also important for evaluation of ultimate efficacy any pulp capping agent. To observe immediate inflammatory response of Human Dental Pulp capped with Mineral Trioxide Aggregate (MTA), Biodentin and Portland Cement (PC). Methods: A total of 70 permanent premolars teeth planned to be extracted for orthodontic alignment of occlusion were used as study sample. The teeth were divided into 3 experimental groups, MTA (n=20), Biodentin (n=20) Portland cement (n=20) and control group (n=10). After having an occlusal exposure of approximately 1.5 mm in diameter; in group A, pulp of teeth was capped with 2-mm-thick layer of ProRoot White MTA (Dentsply) and in group B, with sterile Biodentin (Septodont) according to the manufacturer’s recommendations. Whereas in group C, pulp of teeth was capped with sterile Portland Cement (PC). After placing the experimental material in each group, all teeth restored with glass i‹xiomer cement. After 24 hours the teeth were extracted, fixed in 10% buffered formalin solution, then decalcified by 10% nitric acid and embedded in paraffin. Finally, sectioned into 2 to 3-micron-thick serial sections in the linguo-buccal plane and stained with hematoxylin-eosin. After then the amount of pulp inflammation (type, intensity, and extension) were determined by using a predetermined evaluation criterion under an optical microscope at 40a magnification. Ten intact teeth, which received no exposure and pulp capping but extracted due to orthodontic purpose were also collected and treated as the control group (group D); undergone same histologic preparation and evaluation. Significantstatistical differences among the experimental groups were to be found (p<0.05). Results: Histologically, all the three tested materials produced immediate pulpal tissue reaction. ‘Biodentin’ found to be most immediate pulpal tissue reactive (reactive in 100% cases) and ‘Portland Cement’ showed least immediate tissue reaction (only in 30.0% cases). whereas, MTA produced immediate tissue reaction only in 50.0% cases. Immediate pulpal inflammatory reaction in response to tested material found to be statistically significant different between ‘Biodentin’ and ‘Portland cmient’ (p=0.01), also between ‘Biodentin’ and ‘MTA’ and (p=0.001); but there was no statistically significant difference between ‘MTA’ and ‘Portland cement’ (p =0.197). Conclusion: Considering the maximum immediate pulpal tissue reaction (Inflammation), Biodentin is expected to produce most favorable ultimate bioactivity (biomaterial mineralization) after pulp capping.

Antibacterial Evaluation

Mineral trioxide aggregate (MTA) is an ideal yet costly endodontic sealer material. Tricalcium silicate-white Portland cement (TS-WPC) seems to have similar characteristics to those of MTA. This work aims to characterize a modified TS-WPC and evaluate its antibacterial properties as a potential endodontic sealer material. The modified TS-WPC was synthesized from a 4:1 mixture of sterilized Indocement TS-WPC and bismuth trioxide using a simple solution method with 99.9% isopropanol. The mixture was stirred until it was homogenous, centrifuged, and dried. The material was then characterized using infrared spectroscopy, X-ray diffraction, and electron microscopy and subjected to antibacterial evaluation against Enterococcus faecalis using a Mueller–Hinton agar inhibition test. The results showed that the material was characterized by main functional groups of hydroxyls, silicate, bismuth trioxide, and tricalcium silicate, like those of a commercial MTA-based sealer, both tested after hydration. Modified TS-WPC before hydration showed similar powder morphology and size to the commercial one, indicating the ease of manipulation. Both materials exhibited antibacterial activity due to calcium dihydroxide’s ability to absorb carbon dioxide, which is essential for the anaerobic E. faecalis, with minimum inhibitory effect and bactericidal concentrations of 12,500 ppm and 25,000 ppm, respectively. The modified TS-WPC has the potential to become a cost-effective alternative endodontic sealer material.

Pulp capping has been suggested as one treatment of choice after pulp exposure. Calcium hydroxide [Ca (OH)2] recognized as gold standard of direct pulp capping matter for some decades. Throughout the time, a new cement known as mineral trioxide aggregate (MTA) has developed into a prominent alternative. A recent study found that matter as the most effective pulp capping material. Despite the fact, MTA is an expensive material. Several studies in different country show that portland cement has highly similarity chemical composition with MTA. The purpose of this study is to evaluate the chemical composition of white portland cement that fabricated in Indonesia compared to MTA. White portland cement fabricated in Indonesia was used as a sample in this study and commercial MTA as a control. Samples and control were assessed using X-ray fluorescence spectrometry (XRF) to figure out chemical composition and concentration. Investigating the wavelength of the functional group using Fourier Transform Infrared Spectroscopy (FTIR). The results show that composition, concentration, and functional group either Indonesian white portland cement and MTA has highly similar. Hence, it has a chance to use Indonesian white portland cement for dental pulp capping material as MTA substitution.
