This study evaluated the load-bearing capacity of fiber-reinforced composite (FRC) direct inlay-retained resin-bonded fixed dental prosthesis (RBFDP) made bulk-fill or conventional hybrid resin – composites after cyclic loading. Sound human teeth (N = 50) were embedded in acrylic until cemento-enamel junction (CEJ) and randomly divided into five experimental groups to receive RBFDPs: (a) Sonic ...

AIM To evaluate the remineralization potential of enamel surface lesion using chicken eggshell powder (CESP) solution. MATERIALS AND METHODS Ten freshly extracted un-erupted third molars decoronated at cement-enamel junction (CEJ) used in this study. Each decoronated tooth was sectioned to get 4 samples of enamel blocks such that 40 blocks were obtained which were then subjected to deminerali...

INTRODUCTION This study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. MATERIALS AND METHODS This study was performed on total of 30 first and second extracted molar teeth (15 each). The mesiobuccal roots of each tooth were separated at the cement-enamel junction (CEJ) level and embedded in acrylic resin. The embedded roots were cut ...

background and aims. despite the increasing demand for adhesive restorations in pediatric dentistry, polymerization shrinkage and subsequent marginal microleakage remains a problem. the aim of this study was to evaluate of the sealing ability of novel low-shrinkage composite silorane in class v cavity of primary canines in comparison with three types of composite resin. materials and methods. n...

AIM The aim of this in vitro study was to investigate the cervical microleakage and internal voids of nanocomposites comparing them with a hybrid composite in Class II restorations with the margins located coronal and apical to the cementoenamel junction (CEJ). METHODS AND MATERIALS Standardized MOD cavities (one cervical margin located in dentin, one in enamel) were prepared in 40 extracted ...

OBJECTIVE This study was conducted to evaluate the microshear bond strength (μSBS) and ultramorphological characterization of glass ionomer (GI) cements; conventional GI cement (Fuji IX, CGI), resin modified GI (Fuji II LC, RMGI) and nano-ionomer (Ketac N100, NI) to enamel, dentin and cementum substrates. MATERIALS AND METHODS Forty-five lower molars were sectioned above the cemento-enamel ju...

The gingiva surrounds each tooth and comprises the free gingival(gingival margin), attached gingiva and gingival sulcus. The attached gingiva is firmly attached to the underlying periosteum of the alveolar bone. It is continuous with the alveolar (or oral) mucosa and is demarcated from it by the muco-gingival junction. The free (or marginal) gingiva is that found coronal (ie towards the crown) ...

Background and Objectives: The current study aimed to compare the amount of interdental bone loss between early immediate implant placements. Materials Methods: A total 16 implants radiographs were included in research. level was assessed at two different stages: extraction appointment (T1) after three six months placement (T2). line drawn from cemento-enamel junction connecting adjacent teeth ...

Recently a visually pleasing smile has become major concern for the patients; therefore, dental bleaching gained importance due to its safety and great aesthetic results. A female patient presented with intrinsic discolorated maxillary central incisors after endodontic therapy. Maxillary were isolated rubber dam 2mm of gutta-percha was removed in an apical direction beyond cemento-enamel juncti...
