EFFECT OF AMBIENT TEMPERATURE ON THE SHEAR BOND STRENGTH OF GLASS IONOMER LUTING AGENT- AN IN VITRO STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 28
Abstract
BACKGROUND Ambient temperature is one of the important factors affecting the setting of GICs when used as a luting agent for cementation. This in vitro study was planned to evaluate the effect of ambient room temperature on shear bond strength of GI luting agent. MATERIALS AND METHODS The occlusal surface of the extracted caries free 1st mandibular right molar teeth was ground flat, which was embedded in the body of auto-polymerising resins. The impression of the tooth was made with the copper tube technique and cast was poured. A casting of dental alloy was fabricated with an attachment of 13 mm long and 3 mm thick on the occlusal surface. The glass ionomer was mixed according to manufacturer’s instruction and applied on the tooth and casting under the static load of 2 kg and allowed to set for 10 minutes. The specimen was tested on the Instron universal testing machine to determine the bond strength. Each test was performed for 10 times under three ambient temperature conditions, viz. 16°2°C (Group I), 242°C (Group II) and 34°2°C (Group III). Data was analysed using SPSS 20.0 software. Kruskal-Wallis test followed by Mann-Whitney U test was used to analyse the data. RESULTS Mean shear bond strength of Groups I, II and III was 6.410.28, 6.110.19 and 5.850.16 MPa respectively. Inter and between group differences were significant statistically (p < 0.05). CONCLUSION With increasing ambient temperature, shear bond strength of GI luting agent showed a significant decrease. Further studies to recognise optimal temperature conditions are recommended.
