A Framework to Establish Diet and Nutrition Competencies for Oral Health Care Education

Journal of Dental Education, EarlyView.
ABSTRACT Objective: To prevent and manage oral disease, oral health care practitioners (OHCPs) must provide dietary counseling based on nutrition science. OHCPs are often ill‐equipped to provide such counseling due to fragmented and inadequate dietary education, which is typically attributed to limited curricular time or appropriately qualified faculty.

Macroscopic, Histological and Ultrastructural Features of the Tongue of the Anatolian Wild Boar (Sus scrofa libycus)

Microscopy Research and Technique, EarlyView.
Integrated macroscopic, histological, and ultrastructural analyses revealed five distinct lingual papillae types (filiform, fungiform, conical, foliate, and vallate) in the Anatolian wild boar (Sus scrofa libycus). Mechanical papillae showed marked structural specialization, while gustatory papillae exhibited region‐specific distribution of taste buds.

Independent Prognostic Value of Natural Tooth Count Versus Posterior Teeth Occlusion in Resected Pancreatic Cancer

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background/Purpose Prognostic significance of preoperative patient‐related factors, including oral health status, in pancreatic ductal adenocarcinoma (PDAC) remains unclear. We evaluated the association between preoperative factors—particularly oral health parameters—and long‐term survival after curative PDAC resection.
