The purpose of this study was to investigate differences between natural tooth color and that selected for artificial teeth in partial dentures at our department with a view to establishing criteria for obtaining greater harmonization between colors. The participants in this study comprised partial denture wearers visiting the Department of Prosthodontics, Tokyo Dental College Chiba Hospital, in whom both artificial teeth and natural teeth were present in the maxillary anterior tooth area. Natural tooth color was measured according to VITA classical shade guide number using a dental color measurement apparatus. Artificial tooth color in partial dentures produced at our department was investigated by referring to medical records. Color of 28 participants' natural teeth and 345 participants' artificial teeth was investigated. Differences in color distribution between the natural and artificial tooth were analyzed using the Fisher exact test. The most frequent color of natural tooth was C-type, accounting for 39%, followed by D- at 32%, A-at 22% and B-type at 7%. In terms of artificial tooth color, A-type was the most common (97%). The color distribution of natural teeth differed significantly from that of artificial teeth in partial dentures. These results suggest that artificial tooth color did not harmonize with the color of the natural teeth in partial denture wearers.

Activation of TFEB protects against diabetic vascular calcification by improving autophagic flux and activating Nrf2 antioxidant system.

Autophagic flux blockade and excessive oxidative stress play important roles in the pathogenesis of diabetic vascular calcification (VC). Transcription factor EB (TFEB) is an important regulator of many autophagy-lysosomal related components, which is mainly involved in promoting autophagy process in cells. Nuclear factor erythroid-2 related factor 2 (Nrf2) antioxidant system is considered as one of the key pathways in response to intracellular oxidative stress.

Under-occlusion ('infraocclusion' as defined in the natural teeth) after implant restoration in the posterior area is commonly encountered in clinical practice; however, it has rarely been reported. Most importantly, the under-occlusion change mechanism remains unknown. The purpose of this case report was to analyze how the dentition of both arches changed in a patient, including teeth tilting, elongation and occlusal plane change with under-occlusion of the posterior implant restoration after long-term function.

The field of periodontal regeneration focuses on restoring the form and function of periodontal tissues compromised due to diseases affecting the supporting structures of teeth. Biomaterials have emerged as a vital component in periodontal regenerative therapy, offering a variety of properties that enhance cellular interactions, promote healing, and support tissue reconstruction. This review explores current advances in biomaterials for periodontal regeneration, including ceramics, polymers, and composite scaffolds, and their integration with biological agents like growth factors and stem cells.

The prevalence of oromaxillofacial fracture in pediatric patients is comparatively less than in adults, which could be due to several inconclusive factors, such as infrequent exposure to high-contact sports games, rash driving of vehicles and motorbikes, alcohol consumption, and fist fights for personal reasons under the influence of alcohol. More importantly, most of the time, children are under the care of their parents till they reach an age of maturity. One more thing that everyone believes even today is the elasticity nature of their bones as well as their body weight during their growing stage.

Unlabelled: A new lower tooth plate of from the Turonian (Upper Cretaceous) of the Dalmatian region (southern Croatia) is documented here for the first time. The specimen represents the first articulated dentition of a ptychodontid shark that has been discovered from the Balkan Peninsula and the most complete ever found for the un-cuspidate species up to now. The reconstruction of the entire lower dentition of based on this exceptionally well-preserved dentition shows a wider crushing plate than previously hypothesised with bulgy teeth limited to the central area.
