The ultimate goal of any periodontal plastic surgery aimed to treat gingival recession is predictable recession coverage and esthetic outcome. Due to the post-operative morbidity and discomfort related to subepithelial connective tissue graft, various other methods have been introduced including the use of fetal membranes. The fetal membranes have shown promising results in medicine and recently in the field of regenerative dentistry and could possibly become a viable alternative to autogenous grafts. This article reports a series of cases of Miller's class I gingival recession that were treated by chorion membrane combined with coronally advanced flap and evaluated using objective variables for post-operative healing and esthetics. Nine systemically healthy subjects with ten Miller's class I buccal gingival recession were included in the study. Clinical parameters were recorded at baseline, 3 months and 6 months post-surgery; wound healing index (WHI) was recorded one week post-surgery. At the end of 6 months, the percentage of root coverage and the root coverage esthetic score (RES) were calculated. The results showed statistically significant (p < 0.05) improvement in most of the parameters. The mean percentage of root coverage obtained was 62.20 ± 21.99% ranging from 33.3 to 100%. The WHI showed excellent healing score and RES assessed at the end of six months showed superior esthetic results. The chorion membrane along with coronally advanced flap is a predictable procedure for root coverage with better post surgical healing and superior esthetics.

Background: Newer generation platelet concentrates, such as advanced platelet-rich fibrin plus (A-PRF+) obtained following low-speed centrifugation concept and horizontal platelet-rich fibrin (H-PRF) obtained from swing out and bucket system, showed increased platelet entrapment and growth factor release in the in-vitro studies. This prospective study aimed to evaluate and compare the clinical outcomes of A-PRF+ and H-PRF membranes in the treatment of gingival recession defects. The objectives of this study were to compare the changes in the recession height (RH) and the mean root coverage percentage (MRC%) between and within the research groups.

Background: Total-body (TB) Positron Emission Tomography (PET) is one of the most promising medical diagnostics modalities, opening new perspectives for personalized medicine, low-dose imaging, multi-organ dynamic imaging or kinetic modeling. The high sensitivity provided by total-body technology can be advantageous for novel tomography methods like positronium imaging, demanding the registration of triple coincidences. Currently, state-of-the-art PET scanners use inorganic scintillators.

Soil fungi are essential to ecosystem processes, yet their elevational distribution patterns and the ecological mechanisms shaping their communities remain poorly understood and actively debated, particularly in arid regions. Here, we investigated the diversity patterns and underlying mechanisms shaping soil fungal communities along an elevational gradient (1,707-3,548 m) on the northern slope of the Central Kunlun Mountains in northwest China. Results indicated that the dominant phyla identified across the seven elevational gradients were and , displaying a unimodal pattern and a U-shaped pattern in relative abundance, respectively.

Multiple imputation (MI) models can be improved with auxiliary covariates (AC), but their performance in high-dimensional data remains unclear. We aimed to develop and compare high-dimensional MI (HDMI) methods using structured and natural language processing (NLP)-derived AC in studies with partially observed confounders. We conducted a plasmode simulation with acute kidney injury as outcome and simulated 100 cohorts with a null treatment effect, incorporating creatinine labs, atrial fibrillation (AFib), and other investigator-derived confounders in the outcome generation.

There is a rise in using biologics in root coverage procedures. As it has been shown that hyaluronic acid (HA) promotes wound healing, this review aimed to assess its efficacy in the treatment of gingival recessions.
