Background: Receptor activator of nuclear factor kappa B ligand (RANKL) is one of the key cytokines in the induction of osteoclastogenesis both in vitro and in vivo.Several reports indicated the presence of sRANKL in gingival crevicular fluid of patients with periodontal diseases. Objective: To determine the presence of RANKL in peri-implant crevicular fluid samples of implants with peri-implan...

objectives: this study aimed to compare the diagnostic accuracy of inverted and unprocessed digitized periapical radiographs for detection of peri-implant defects. materials and methods: a total of 30 osteotomy sites were prepared in three groups of control, study group 1 with 0.425 mm defects and study group 2 with 0.725 mm defects using the sic and astra tech drill systems with 4.25mm and 4.8...

Introdouction: Implants are considered to be a useful treatment for the replacement of lost teeth. Although the success rate and durability of implants are high, the prevalence of peri-implantitis is high as well. The purpose of this study was to analyze the knowledge of general practitioners in the city of Rasht in Northern Iran regarding peri-implantitis and its treatment. Materials and meth...
