Fingerprints hold evidential value for individual identification; a sensitive, efficient, and convenient method for visualizing latent fingermarks (LFMs) is of great importance in the field of crime scene investigation. In this study, we proposed an aggregation-induced emission atomization technique (AIE-AT) to obtain high-quality fingermark images. Six volunteers made over 1566 fingerprint samples on 17 different objects. The quality of fingermark development was evaluated using grayscale analysis for quantitative assessment, combining the fluency of fingermark ridges and the degree of level 2 and level 3 features...

UNLABELLED: Bone augmentation prior to dental implant placement is a common scenario in the dental implantology field. Among the important intraoral harvesting sites to obtain bone blocks is the ramus/retromolar region that has a high success rate and long-lasting alveolar ridge augmentation. Preserving the bone volume and quality at the donor site is crucial for preventing further complications or to serve as a site for re-harvesting. Healing of the intraoral donor sites has been described in the maxillofacial field...

BACKGROUND: After tooth extraction, a physiological shrinkage of the alveolar ridge occurs. Applying a buccal overbuilding some months before tooth extraction may create a stiffer hard tissue that might protect the alveolar crest from resorption. Hence, the aim of this experiment was to evaluate the dimensional changes in the alveolar crest after buccal overbuilding performed before tooth extraction. MATERIALS AND METHODS: At the test sites, an alveolar crest overbuilding was performed on the buccal aspect of the distal root of the third premolar using xenograft covered with a collagen membrane...

The anatomy of North American tortoises is poorly understood, despite a rich fossil record from the Eocene and younger strata. Stylemys nebrascensis is a particularly noteworthy turtle in this regard, as hundreds of specimens are known from Oligocene deposits, and as this species is one of the earliest fossil turtles to have been described in the scientific literature. Since its initial description based on a shell, many specimens with more complete material have been referred to Stylemys nebrascensis . Here, we review and confirm the referral of an important historic specimen to Stylemys nebrascensis , which includes shell, non-shell postcranial, and skull material...

All ecosystems face ecological challenges in this century. Therefore, it is becoming increasingly important to understand the ecology and degree of local adaptation of functionally important Arctic-alpine biomes by looking at the most diverse taxon of metazoans: the Arthropoda. This is the first study to utilize metabarcoding in the Alpine tundra, providing insights into the effects of micro-environmental parameters on alpha- and beta-diversity of arthropods in such unique environments. To characterize arthropod diversity, pitfall traps were set at three middle-alpine sampling sites in the Scandinavian mountain range in Norway during the snow-free season in 2015...

Guided bone regeneration (GBR) requires a stable graft-membrane complex. This article presents a novel technique that uses membrane fixation screws to serve as anchors for membrane stabilization sutures without the need for periosteal dissection and biting of the buccoapical periosteum. This technique may be a viable alternative when there is a preference to avoid the complexities of periosteal suturing and direct membrane fixation using tacks or screws. The technique, which utilizes anchoring screws as mooring lines, can be used at the time of tooth extraction as well as for ridge augmentation of an edentulous site in preparation for future dental implant placement...

In recent years, clinicians have paid more attention to the biological and esthetic effects of the 2 mm keratinized mucosa width (KMW) around dental implant. How to increase the keratinized mucosa is the focus of clinicians. While the free gingival graft (FGG) is still the gold standard of keratinized mucosa augmentation, alveolar ridge preservation (ARP), connective tissue graft (CTG) and apically positioned flap (APF) can also be used to obtain more than 2 mm keratinized mucosa width when they are used before implantation, with implantation, within the implant-healing phase, with second stage of implantation or after rehabilitation according to different indications...
