| Summary: | Resin based dental composites is one of the promising dental materials that serves as an alternative to metal and
amalgam restorations, as they resemble natural tooth and widely used in restorative dental treatments such as tooth
decay and oral lesions. Despite several ongoing researches and innovations, the primary challenges associated with
composite restorations are their limited durability, sensitivity, shrinkage and leakage. This research aimed to address
these challenges and develop an innovative dental composite resulting in a minimal discomfort to the patient and
improve long term therapeutic effi cacy. To overcome these challenges silica Nano- particles, with antibacterial agent
was incorporated. Nano- particles of silica acted as filler, which was extracted from a bio-waste (rice husk). The
addition of anti-microbial agents helped to minimize leakage due to shrinkage as these materials have small particle
size, off ering a wide range of biological, chemical and mechanical properties. This was followed by characterization
techniques which includes; SEM, XRD, FTIR and particle characterization that were evaluated and compared. The
peaks of Silicon dioxide in XRD was recorded at 21.67, 38.38 and 44.68. Extracted silica particle size 47. 66 μm was
further reduced to Nano size with an average size of 200 nm. FTIR spectrum showed the relative transmittance at
1000- 1090 cm-1. The results met the standard measures and was much cheaper than currently used in dental industry.
In future, comparative analysis testing including compressive or tensile strength and anti- bacterial testing can be
performed that may further prove its potential and can be followed by clinical trials also. |
