Aim: Ultrasonography (US) has shown accuracy in imaging healthy periodontium. This study aims to evaluate the feasibility and accuracy of US for estimating dimensions of inflamed periodontium induced by ligature and bacteria.
Methods: Periodontal tissues of maxillary as well as mandibular premolars and molars in six female mini pigs were treated with ligature and three strains of bacteria for 4-10 weeks.
Article Synopsis
- The hypothalamic-pituitary-adrenal (HPA) axis is key in stress responses, with Crh from the hypothalamus triggering cortisol release from the adrenal gland, influencing anxiety behaviors in mice.
- A study showed that deleting Crh in the hypothalamus reduced anxiety in mice, but this effect was not observed in cases of primary adrenal insufficiency or after treatment with dexamethasone.
- Despite different genetic backgrounds and DEX treatments, all mouse groups demonstrated similar anxiety levels, suggesting that changes in Crh expression might not significantly impact anxiety in conditions like adrenal insufficiency or glucocorticoid therapy.
Current flap-releasing designs for guided bone regeneration (GBR) emphasize preserving subperiosteal microvasculature by adapting a deep-slit approach, separating the periosteum from the flap. Although biologically sound, a biomechanical disadvantage may be encountered. This study aimed to describe a modified design, the Secured Anatomy-driven Flap Extension (SAFE) technique, for effective facial flap release and to preliminarily evaluate the clinical outcomes of this technique retrospectively.

Their dimensions change during pathological conditions and may correlate with wound-healing status. Non-invasive, high-frequency ultrasound (US) may be able to capture these changes and aid in early detection of histopathological changes.

The goal of this retrospective, multicenter clinical study is to clinically evaluate the relationship between the interradicular conformation and regenerative therapy success with the use of a novel measurement method.
Methods: One hundred thirty-eight radiographs of mandibular molars with furcation defects that had been treated with regenerative therapy were collected from six clinical centers.
