Microleakage of Two Cementing Agents Using Different Application Techniques
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2017, Vol 21, Issue 2
Abstract
The coronal leakage of bacteria and other irritants to the radicular canal system is one of the main factors that may result in clinical failure and affect the long term success of adhesive cementation and endodontic treatment. Thus the aim this study was demonstrated in vitro the degree of marginal microleakage of two cementing agents. 60 bovine incisors endodontically treated. The specimens were randomly divided into two groups: Group 1 – dual-cured resin cement and group 2 - resin-modified glass ionomer cement. Booth groups were divided into three subgroups with 10 teeth each, according to the placement technique to be used: A - applying it with a spatula over the pin; B - lentulo bur; C - Centrix syringe. The teeth were thermocycled for 1000 cycles between 5 and 55°C and a dwelling time of 30 seconds. All groups were immersed in a solution of Rodhamine B at 2% at room temperature for 24 hours. The dye microleakage analysis was performed by three calibrated examiners. After 24 hours, the teeth were longitudinally sectioned and the microleakage scores were given by a blind operator. Data were submitted to Kruskal-Wallis test (p≤0.05). No difference was observed in microleakage values between the insertion techniques for both cements analyzed. The two cements used, as well as the three techniques of insertion techniques generated similar values of coronal microleakage.
