This study reports abrasion, biocompatibility and degradation behavior of Polypropylene (PP)/Sugarcane Ba gasse Ash Particulate (SBAP) composites for possible application as dental implant materials. PP composites were prepared with varying weight per cent of SBAP ranging from 10 – 50 wt% at regular interval of 10. Hard ness test and wear analysis were conducted. Degradation test was performed using different media, namely artifi cial human saliva (AHS), artificial human saliva with sodium floride (ASSF) and Hank’s balanced salt solution (HBSS). Biocompatibility test was conducted using different sex of rats by varying dose injected into their mouth. Results reveal an increase in hardness values and wear resistance with the filler loading. Additionally, the degradation rate of the composites decreases averagely with the filler addition. It was deduced from the results that the composites are biocompatible and non-toxic. Therefore, PP/SBAP composites would be compatible to human body. Hence, the composites could be recommended to be used as dental restorative materials.
