Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Alveolar Socket Sealing Using Mucosal Grafts for Alveolar Ridge Preservation

Cakradonya Dental Journal
The fresh extraction socket in the alveolar ridge poses a significant challenge in clinical practice, requiring the preservation of both the hard and soft tissue envelope to maintain stable ridge volume.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Dimensional changes of hard and soft tissues in post-extraction sites: evaluation of two biomaterials

Revista Facultad de Odontología Universidad de Antioquia, 2016
Introduction: the techniques for alveolar ridge preservation with different biomaterials show better healing processes than those treatments which do not carry out procedures nor modify the patterns of alveolar bone resorption. The goal of this study was

Changes in PGE2 signaling after submandibulectomy alter post–tooth extraction socket healing [PDF]

, 2018
Saliva is very important to oral health, and a salivary deficit has been shown to bring serious problems to oral health. There is scant information about the mechanisms through which salivary glands participate in post–tooth extraction socket healing ...

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

The Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Fabrication and anti-microbial evaluation of drug loaded polylactide space filler intended for ridge preservation following tooth extraction

Journal of Indian Society of Periodontology, 2011
Background: The preservation or reduction of alveolar ridge resorption following tooth extraction is important in patients especially for those intended for implants at a later stage.

Beyond wound sealing: A dual‐functional adhesive nanofiber membrane promoting coagulation and osteogenesis in extraction sites

BMEMat, EarlyView.
Inspired by the suction mechanics of octopus suckers, a dual‐layer nanofiber membrane integrates antibacterial protection, strong wet adhesion, and osteogenic support, offering a bioinspired strategy for effective hemostasis and alveolar bone preservation.

The effect of platelet-rich fibrin (PRF) versus freeze-dried bone allograft (FDBA) used in alveolar ridge preservation on the peri-implant soft and hard tissues: a randomized clinical trial

BMC Oral Health
Background The effectiveness of alveolar ridge preservation on bone regeneration and tissue healing has been thoroughly documented in the literature.

Evaluation of the Effectiveness of the Socket Preservation Technique Using Allogeneic and Xenogeneic Materials—A Preliminary Study

Journal of Functional Biomaterials
Background: The socket preservation technique involves filling the bone defect created after tooth extraction with a bone substitute material. This helps to reduce bone resorption of the post-extraction alveolar ridge.
