Clinical practice guideline of the Spanish society of oral surgery for dental care in patients with oral cancer.

Background: Oral cancer is the sixteenth most common malignant neoplasm worldwide, with a high mortality rate, greater than 50% at five years, and high morbidity. The effect of oncological treatment in the oral cavity is broad and has multiple levels, therefore knowing these effects and preventing them is essential for avoiding an increase in the oral pathology related with oncological therapy, maintaining the quality of life of the patient, and improving the efficacy of the treatment itself.

Material And Methods: A group of experts belonging to the fields of Dentistry, Maxillofacial Surgery and Oncology of the University of Seville and the Virgen del Rocío University Hospital of Seville in collaboration with the University of Valencia, University of Barcelona, and University of the Basque Country, developed this Clinical Practice Guideline for the proper clinical management of patients diagnosed with oral cancer.

Evaluation of the inflammatory and osteogenic response induced by titanium particles released during implantoplasty of dental implants.

Implantoplasty is a mechanical decontamination technique that consists of removing the threads and polishing and smoothing the dental implant surface. During implantoplasty there is a large release of titanium metal particles that might provoke a proinflammatory response and reduce the viability of osteogenic cells. We analyze the inflammatory and osteogenic response induced by Ti6Al4V particles released during implantoplasty and by as-received commercially pure Ti particles.

Mechanical Properties and Corrosion Behavior of Ti6Al4V Particles Obtained by Implantoplasty: An In Vitro Study. Part II.

In the field of implant dentistry there are several mechanisms by which metal particles can be released into the peri-implant tissues, such as implant insertion, corrosion, wear, or surface decontamination techniques. The aim of this study was to evaluate the corrosion behavior of Ti6Al4V particles released during implantoplasty of dental implants treated due to periimplantitis. A standardized protocol was used to obtain metal particles produced during polishing the surface of Ti6Al4V dental implants.
