Objective: Due to their consistent and individualistic patterns, palatal rugae (PR) are used in forensic dentistry as an ancillary method for personal identification. This study aimed to compare the impression of the PR obtained with the classic alginate impression and casting of the plaster model with the impression of the palate made with an intraoral scanner. Both impressions were compared with each other and with the photograph of the palatal rugae.

Article Synopsis
  • Paraneoplastic pemphigus (PNP) is a rare autoimmune disorder linked mainly to Non-Hodgkin Lymphomas, typically seen in adults aged 45 to 70.
  • A review of 87 articles focused on PNP's oral symptoms, highlighting important histological (microscopic tissue structure) and serological (blood test) findings.
  • Key insights indicate that PNP is frequently diagnosed before any associated cancers, with the follicular variant of Non-Hodgkin Lymphoma being the most common connection, necessitating better diagnostic criteria and serological testing methods.

Article Synopsis
  • This study investigated the oral signs and symptoms associated with paraneoplastic syndromes by analyzing data from various medical databases.
  • A systematic review found that common oral issues included conditions like paraneoplastic pemphigus, mucous membrane pemphigoid, and acanthosis nigricans, with the palate being the most affected area.
  • The findings indicate a high prevalence of mortality (50.9%) and a notable remission rate (63.4%) after treatment, highlighting the need for further research to improve diagnosis and patient care.

Nikolsky's sign, originally described for skin lesions, presents challenges when applied to the oral mucosa. To address this, a modified Nikolsky's sign has been proposed specifically for the oral mucosa. In this variant, a gentle breath of air from the air syringe embedded in the dental unit is used to inflate a pre-existing collapsed blister (non-induced technique).

Hepatitis C virus (HCV) infection is a global health concern with significant systemic implications, including a range of oral manifestations. This review aims to provide a comprehensive overview of the oral and dental pathologies related to HCV, the etiopathogenetic mechanisms linking such conditions to HCV and the impact of direct-acting antiviral (DAA) therapy. Common oral manifestations of HCV include oral lichen planus (OLP), periodontal disease, and xerostomia.
