AN EVALUATION OF THE PHYSICAL PROPERTIES OF A NEW ATRAUMATIC RESTORATIVE TREATMENT MATERIAL CONTAINING AZADIRACHTA INDICA (NEEM)
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 38
Abstract
BACKGROUND This in vitro experimental study investigated and compared the physical properties of three newly developed atraumatic restorative treatment materials. MATERIALS AND METHODS Atraumatic Restorative Treatment materials (ART) with three different compositions were prepared by varying the percentage of Azadirachta indica (Neem) extract within the materials. Micro-hardness, compressive strength, marginal adaptation to tooth structure of the atraumatic restorative treatment materials were assessed. Statistical Analysis Used- Data was analysed using SPSS version 20 statistical software. One-Way ANOVA, Tukey’s Highly Significant Difference (HSD), Scheffe’s tests were conducted to assess the level of significance of differences between mean values in post-hoc testings. P < 0.05 was considered statistically significant. Settings and Design- Samples were prepared in the Department of Oral Biology and Genomic Studies, AB Shetty Dental College and experiments were conducted in NITK, Surathkal. RESULTS The micro-hardness of ART-I was found to be 21.1 - 25.8 VHN, whilst ART-II showed values between 13.2 - 16.3 VHN. The compressive strengths of ART-I and II were 38.2 - 56 and 43.3 - 61 MPa respectively. The micro-hardness of the ART-III was from 35.3 - 36.4 VHN. However, the compressive strength of ART-III was 31.2 - 38 MPa. Micro-hardness was recorded as significantly high when compared between the groups (P < 0.0001). Although, there were no significant differences in compressive strengths between the ART-I and ART-II materials (P > 0.05), the compressive strength of ART-III was significantly greater than those of the ART-I and II (P < 0.05). No marginal gap was observed between the walls of the cavities in extracted teeth and restorative ART-II, whereas these were found when employing the ART-I and III products. CONCLUSION The ART-II product evaluated physical properties consistent with promising Atraumatic Restorative Treatment materials, unlike the ART-I and III.
