“…In this study 850°C sintering temperature was used. In a recent study, Pongkao et al prepared HA with calcinating method from cattle bone at 700°C in air for three hours [12]. Guizzardi et al used ashing method at 400°C and also deproteinized the samples at sodium hypochloride.…”

Different types of bone-graft substitutes have been developed and are in the market worldwide to eliminate the drawbacks of autogenous grafting. They vary in composition, strength, osteoinductive and osteoconductive properties, mechanism and rates by which they are resorbed and remodelled. Tooth derived hydroxyapatite (THA) is a novel biomaterial. This study was performed to determine the histological properties of THA on animals. A commercial coralline HA (CHA, Proosteon 200, Interpore Cross, USA) was used as control material. 20 sheeps were used and divided into 2 groups. Human THA (Group A) and CHA (Group B) materials were implanted to the tibiae of 10 sheeps for each group. The histological examinations of surrounding bone response were done 12 weeks after implantation. There was no significant difference histologically between group A and B. All materials were found to be surrounded by new bone tissue. THA was found to be as efficient as the standard CHA on histological basis. In addition, economical production of THA should be taken into consideration. Therefore, THA may be a viable alternative on bone grafting provided that clinical trials will be completed.

“…In a recent study, Pongkao et al prepared HA with calcinating method from cattle bone at 700?C in air for 3 hours. They had reported that the Ca: P ratio was 1.66 (heavy metals such as; As ?0.5 ppm, Cd ?0.5 ppm, Pb ?5 ppm, Hg ?1 ppm) [18]. Guizzardi et al used ashing method at 400?C and also deproteinized the samples at sodium hypochloride.…”

Abstract-Different types of bone-graft substitutes have been developed, and are on the market worldwide to eliminate the drawbacks of autogenous grafting. They vary in composition, strength, osteoinductive and osteoconductive properties, mechanism and rates at which they are resorbed and remodelled. Of these, THA is a novel material produced by one of us (FNO). This study was performed to determine the histological properties of THA on animals, and to achieve this a standard on the market coralline HA (CHA) was used as control. 20 sheep were used in this study and divided into 2 groups. Human THA (Group-A) and CHA (Group-B) materials were implanted to the tibiae of 10 sheep in each group. The histological examinations of surrounding bone response of the implant materials were done 12 weeks after implantation. There was no significant difference histologically between groups A and B. All materials were found to be surrounded by new bone tissue. THA was found to be as efficient as standard CHA on histological basis. In addition, economical production of THA should be taken into consideration. In future, THA may be a viable alternative on bone grafting when clinical trials were completed.
