“…With regard to the bone healing, the choice of rabbits as an animal model in our study has advantages such as suitable size, cost and easy handling. In addition, some similarities are reported in the bone mineral density and Haversian remodeling which occurs faster in rabbits 3,33 The present study evaluated the biocompatibility and the bone healing efficacy following the WPC graft material in experimentally created intrabony defects in rabbit's mandible. In this study the animals were euthanized for evaluation at 1, 4 and 8 weeks after surgery, this research model was selected to be safe for the preservation and quality of animal's life until the end of the evaluation period.…”

“…PC is the most common cement used in civil engineering applications. PC was created and patented in 1824 by an English builder named Joseph Aspdin 3 . The major components of ordinary Portland cement (OPC), which are similar to those of mineral trioxide aggregate (MTA) 4 , consist of tricalcium silicate, dicalcium silicate, tricalcium aluminates, tetra-calcium aluminoferrate, and calcium sulfate dihydrate 5 .…”

Back ground: white Portland cement (WPC) is a fine powder and most common type of cement in general use around the world. This study was carried out to evaluate in vivo biocompatibility and bone healing efficacy of WPC in surgically mandibular bone defect rabbits. Material and methods: Fifteen rabbits were divided randomly into three equal groups (I, II& III). Surgical defect was made at posterior submandibular region on both right and left sides. Sterile WPC powder was applied to the left side defect, while the right side was control. The groups (I, II, III) were sacrificed after 1st, 4th and 8th week postoperatively respectively. The specimens were processed for light microscope using H&E and SEM. The newly formed bone filling the defect and cell counting were statistical evaluated.. Results: The experimental sides of all periods revealed increasing in the amount of newly formed bone trabeculae extended from original bone towards the center of the defect. While, the control sides displayed few new bone trabeculae at central area and the lateral wall of the bony defects. The amount of newly formed bone and mean cell counting confirmed the histological results. Conclusion: WPC is a biocompatible osteoconductive economically affordable graft material.

“…Calcium silicate-based materials are a potential candidate for bone tissue engineering due to their good physical properties, biocompatibility and acceptable bioactivity and osteoconductivity [38]. Portland cement stimulates the expression of bone remodeling markers and the growth of bone tissue with the formation of osteoid and new trabeculla [39,40]. The behavior of osteoblast lineage cultured on Portland cement has been previously discussed.…”

Background Portland cement has promisingly been utilized for reconstruction of root perforation and bone defects, although its key drawbacks including low mechanical properties and radiopacity as well as long setting time necessitate pragmatic modifications. Objective The main objective of this review was an overview on portland cement as a root repair material, its applications and various modifications. Methods The electronic search of the literature was done on the Pubmed and Google Scholar databases with the keywords of Portland cement, carbon nanotube, graphene oxide, MTA, pulp capping, root repair material. Results The first part of this paper presents the data published in the literature on applications of Portland cement in endodontic situations including vital pulp therapy, root perforation repair, root canal filling and root-end filling following apical endodontic surgery. This bioactive endodontic cement has shown promising success rates compared to mineral trioxide aggregate (MTA), however, considerable modifications are required in order to improve its clinical performance and expand its application scope as a root repair material. Hence, nano-reinforcements (graphene oxide, carbon nanotube, silica and hydroxyapatite) and extensive chemical modifications incorporated into Portland cement composition to produce innovative bio-dental materials with superior rheological properties have been discussed. Moreover, the current knowledge on the microstructure, mechanical properties and durability of nanomaterial-incorporated cement has been summarized. Ultimately, this article outlines the main points of animal and clinical studies on resin-modified Portland cement (TheraCal) as a pulp capping material and suggests further investigations prior to marketing authorization. Conclusion It can be concluded that Portland cement has the potential to be used as an acceptable pulp capping material with the least complaints in the long term.
