Microscopic and virtual approaches to oral pathology: a case study from El Mirador Cave (Sierra de Atapuerca, Spain)
(Annals of Anatomy - Anatomischer Anzeiger, 2022-01)Background: The analysis and diagnosis of ancient oral pathologies have been improved with the application of new techniques such as microscopy and scanning methods over the past few decades. However, ... -
Multidisciplinary management of an external cervical resorption and cemental tear
(Giornale Italiano Di Endodonzia, 2021)A 53-year-old man was referred to the University Dental Clinic complaining of a pink spot that he noticed on his right maxillary central incisor. After thorough clinical and radiographic examination, ... -
Multimodal analgesia in orthognathic surgery
(Journal of Oral and Maxillofacial Anesthesia, 2022)Orthognathic surgery, as part of maxillofacial surgery, involves the correction of dentofacial deformities for both functional (occlusion, speech and sleep disturbances) and aesthetic reasons. Deformities ... -
