Comparative Microleakage Evaluation through the Interfaces between the Tooth and Cement after Stainless Steel Crown Cementation in Primary Molars: An In Vitro Study (original) (raw)
International Journal of Clinical Pediatric Dentistry
plentiful for an alpha of 0.05, power of 80%, 0.5 as effect size (estimated from an analogous study). Forty five extracted deciduous molars were selected with root resorption less than two-thirds according to the inclusion criteria. The extracted teeth were immersed in 10% formalin solution for 2 weeks for sterilization. Then the teeth were preserved in distilled water at 37°C. Firstly, a columnar acrylic block was formulated of height 1.5 cm and 1.5 cm width. Following which a rubber IntroductIon Caries is one of the leading oral issues affecting children. The consequences of untreated lesions cause pain and infection. 1 Full coronal restorations may be indicated where multiple surfaces are affected and when pulpal therapy is indicated. 2 Stainless Steel Crowns (SSC) are fitted onto respective teeth and affixed with a biologically adaptable cementing agent, 3 primarily filling voids at restoration-tooth interface. Recently, newer agents have been introduced claiming superior performance than predecessors. 4 Since scanty literature exists regarding microleakage relating to newer luting agents, the current research was attempted to compare and assessability of new adhesive luting agents to halt microleakage under SSCs on primary teeth. MaterIals a n d Methods The present study was performed in the Department of Pedodontics and Preventive Dentistry. In the current study, the ability of new adhesive cement, that is, Conventional Glass Ionomer Cement, Resin Modified Glass Ionomer luting agents, as well as Resin-based luting agents, were compared and evaluated to avert microleakage beneath stainless steel crowns on primary teeth. Sample size evaluation was done using G Power software (version 3.0). The sample size was assessed for the F test and "ANOVA: fixed effects, one way" was chosen. The lowest aggregate sample size of 45 (15 per cement group
