Accuracy of the estimation of dental age in comparison with chronological age in a Spanish sample of 2641 living subjects using the Demirjian and Nolla methods.
Age estimation is an important procedure in forensic medicine and is carried out for a number of reasons. For living persons, age estimation is performed in order to assess whether a child has attained the age of criminal responsibility, in scenarios involving rape, kidnapping or marriage, in premature births, adoption procedures, illegal immigration, pediatric endocrine diseases and orthodontic malocclusion, as well as in circumstances in which the birth certificate is not available or the records are suspect. According to data from the UNHCR (United Nations High Commissioner for Refugees), the number of people seeking refugee status continued to increase in the last years, driven by the w…
Interleukins IL-6, IL-8, IL-10, IL-12 and periimplant disease. An update
Introduction: A study is made of the usefulness of cytokines (such as interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and interleukin-12 (IL-12)) as markers of periimplant disease (mucositis and periimplantitis). An increase in the levels of these cytokines in dental implant crevicular fluid may give rise to a lack of osteointegration, bbone loss or implant failure. Obbjective: To review the literature relating IL-6, IL-8, IL-10 and IL-12 levels to dental implant surgery and periimplantitis. Material and Method: A PubbMed literature search was made of articles in English and Spanish, using the key words "cytokine and dental implants", cytokine and periimplantitis", "IL-6,…

Eagle syndrome compared with stylohyoid syndrome: complete ossification of the stylohyoid ligament and joint
A 65-year-old man presented with a history of type 2 diabetes, chronic obstructive pulmonary disease, and non-alcoholic fatty liver. He had had no injuries to, or operations on his neck, but had had right submandibular and retroauricular pain for years. Computed tomography with 3-dimensional reconstruction (Figs. 1 and 2) showed elongation of both styloid processes associated with pseudoarticulation of the hyoid bone on the right side. This confirmed the complete ossification of the stylohyoid ligament, but the patient did not want an operation to resolve it.

A Classification Proposal for Peri-Implant Mucositis and Peri-Implantitis: A Critical Update
Definitions of peri-implant mucositis and peri-implantitis vary in the literature, and no clear criteria have been established for the diagnosis and treatment of such disorders. This study proposes a classification for peri-implant mucositis and peri-implantitis based on the severity of the disease, using a combination of peri-implant clinical and radiological parameters to classify severity into several stages (Stage 0A and 0B = peri-implant mucositis, and Stage I to IV = periimplantitis). Following a review of the literature on the subject and justification of the proposed peri-implant disease classification, the latter aims to facilitate professional communication and data collection for…
