| description | The aim of this finite element analysis study is to evaluate the stress distributions of different types of restorative materials at Class I cavity in the primary molar. The non-cracked caries-free primary mandibular second molar that is extracted for orthodontic reasons is used to create a three-dimensional model. Two models were prepared as Model 1: the tooth model without restoration (control group) and Model 2: the tooth model with Class I restoration. Five different types of restorative materials were tested in Model 2 (resin modified glass ionomer [Fuji II LC], compomer [Dyract AP], giomer [Beautiful II], glass carbomer [GPC Glass Fill] and ionic resin material with bioactive properties [Activa Kids Bioactive]). A force of 197 N was applied in the vertical and oblique directions in the ANSYS program (Ansys Workbench 19.0, Canonsburg, PA). The maximum Von Mises stress values were compared in the models. The vertical or oblique loading created different stresses in enamel, dentin and restorative materials. The stresses in the enamel tissue were higher than that in the dentin tissue. The stresses in vertical loading were higher than in the oblique loading for restorative materials. The different restorative materials exhibited similar stress distribution patterns, except Activa Kids Bioactive (vertical and oblique loading 446.16 and 8.57, respectively). |
