In addition, it was concluded that the results of this study are material dependent as well as being dependent of the type of dentin primer. “
“Although unusual, foreign body ingestion occurs in dentistry and may result in serious complications, such as intestinal perforation. The presence of the foreign body should be confirmed with the use of radiographs. The exam will allow the correct diagnosis and the treatment to be conducted according to the specific situation of the object in the gastrointestinal (GI) tract. The orientation Wee1 inhibitor of the patient as well as the awareness of the patient’s medical history are key factors in preventing

serious complications. Generally, instruments that enter the GI tract pass asymptomatically and atraumatically within 4 days to 2 weeks. Sometimes, a surgical approach is necessary to remove the instrument when there is bleeding, obstruction, or impaction in the GI tract. Thus, a correct diagnosis is vital to avoid unnecessary surgical interventions. The aim of this article is to report an accidental ingestion of a screwdriver by a patient who had previously undergone a hemi-mandibulectomy Ridaforolimus and its medical resolution. “
“This study analyzed the impact of cement layer thickness (CLT) and Young’s modulus of the cement on the stress distribution in a three-unit zirconia fixed dental

prosthesis (FDP) and in the bonding interfaces by means of finite element method. A 3D finite element model was created from a stylized three-unit FDP-cement-tooth/socket system. The pulp and the periodontal ligament were not modeled. Two CLTs (50 and 150 μm) and two values of Young’s modulus of the cement Tobramycin (4.9 for simulation of resin cement, 20.1 GPa for glass ionomer cement) were evaluated. A 500 N static vertical load was applied at the central fossa of the pontic to calculate maximum displacement in the framework and maximum principal stresses in both framework and bonding interfaces. The simulated results showed that the Young’s modulus affected stress occurrence only in the cement interface. Lower moduli were associated with less stress. The thickness of the cement layer influenced

the maximum principal stress in both the FDP and in the cement layer itself. Thicker cement layers led to higher stresses in the framework but lower stresses in the cement layer. Maximum displacement was less dependent of the investigated variables. During all trials, the location of the maximum principal stress did not change. Maximum stress concentrations were observed at the lower embrasures of the connector areas and in the bonding layer at the cervical margin of the preparation. Choosing cements with a preferably low Young’s modulus in combination with a CLT as small as possible might increase the clinical survival rate. “
“While the incorporation of antimicrobial agents into soft denture liners has been suggested as a reliable alternative treatment for denture stomatitis, it may affect the liner’s properties.
