A COMPARITIVE EVALUATION OF VIVASENS AND SYSTEMP DESENSITIZERS ON SHEAR BOND STRENGHT OF COMPOSITE RESIN TO HUMAN DENTIN: AN IN VITRO STUDY.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 4
Abstract
Background Post-restorative dentinal hypersensitivity is a common occurrence and happens due to the movement of the dentinal fluid in the exposed tubules, which excites the pulpal nerves resulting in perceived sensation. The use of dentin desensitizers has been one of the most common approaches for management of post- restorative dentin hypersensitivity. Material & Methods 36 human premolars extracted for orthodontic purpose were collected after taking patient’s consent in Sri Siddhartha Dental college, Tumkur. Shear bond strength test was done using Instron universal testing machine at RV-TIFAC composite design center, Composite technology park, Bangalore. The teeth were carefully cleaned using a hand scaler and water-pumice slurry in prophylaxis rubber cups and stored in 0.1% thymol solution until subjected to use. The sample teeth were assigned to the following product (Table 1) groups: Groups: Per group (n = 12), Group 1: Prime and Bond NT, Germany, Group 2: Vivasens desensitizer, Ivoclar Vivadent Schaan, Liechtenstein, Switzerland, Group 3: SystemP, Ivoclar Vivadent Schaan, Results The mean shear bond strength between all the groups was statistically significant. So further pairwise comparisons between the groups was carried out using Mann-Whitney test. The test result shows that Group 1 values statistically significant difference between Group II and Group III (P<0.05). Conclusion Within the limitation of the present in vitro study SystemP desensitizer is considered to be a promising option for the treatment of dentin hypersensitivity and to enhance bond strength during composite resin restorations. It can be stated that use of desensitizers showed increased shear bond strength values as compared to application of the adhesive alone. The SystemP desensitizer have better bond strengths than Vivasens.
