The purpose of this study was to evaluate the efficiencies of different irrigation protocols in the removal of triple antibiotic paste (TAP) from root canals. ⋯ The use of irrigation systems improved the removal of TAP from the simulated immature root canals. Also, as an irrigation solution EDTA gives more promising results than PAA and HEBP solutions.

Age estimation plays a significant role in forensic science, archeology, pediatric endocrinology and clinical dentistry. Tooth development is a reliable pathway for age estimation, especially in children. The aim of this study was to evaluate the accuracy of the Demirjian method (DM), Willems method (WM) and Cameriere method (CM). ⋯ In conclusion, this study indicated that WM determines DA satisfactorily in a Turkish subpopulation.

Fractures in porcelain laminate veneers (PLVs) are a significant clinical problem. Preparation designs can affect stress distribution, which leads to fractures in PLVs. Therefore, identification of the most favorable preparation design in terms of stress distribution is required. ⋯ Both the preparation design and load angle affected the stress distribution on the PLVs. The incisal bevel preparation design provided a more appropriate geometry for stress distribution compared with the other techniques. Lateral forces produced more stress on the tooth and laminate material than vertical forces.

The aim of the present study was to evaluate the effects of self-etch and self-adhesive resin cements on the shear bond strength of ceramic core materials bonded to dentin. ⋯ The self-etch adhesive resin cements exhibited better shear bond strength than the self-adhesive resin cements, except for Panavia cement in the IPS e.max Press group. However, shear bond strengths of the self-adhesive resin cements were dependent on the nature of the ceramic core materials.
