ABSTRACT Aim To assess tissue perfusion changes and wound healing biomarker levels after root coverage procedures with coronally advanced flap in combination the cross‐linked xenogeneic collagen matrix (CCMX), loaded either a placebo or recombinant human platelet‐derived growth factor‐BB (rhPDGF). Methods This study was designed as secondary analysis from previously published clinical trial, it assessed over 6 months around multiple gingival recession defects, treated CCMX alone (control) + rhPDGF (test). High frequency Doppler ultrasonography (HFUS) scans were obtained at sites of interest baseline, 2 weeks, 3 months, surgery. Dynamic measurements (DTPMs) performed midfacial, interproximal, transverse aspects teeth by an operator, blinded to treatment allocation, using software package. The expression different biomarkers crevicular fluid also assessed. Results regression analyses showed similar between two groups throughout majority months. DTPMs weeks test group have significantly higher relief intensity (pRI, p < 0.001), mean perfused area (pA, blood flow (FI , = 0.021), total tot 0.021) graft region (ROI) compared control sites. exhibited greater pA ( 0.033) “blue” blue meaning away transducer, 0.035) level At FI directly correlated final 0.008) complete 0.003). direct correlation volume gain 0.031 for both parameters).

ABSTRACT Introduction The aim of this study was to evaluate perfusion parameters and clinical features healthy implants affected by peri‐implant disease in patients who had undergone microvascular jaw reconstruction. Methods A total 25 with 92 placed transplants were included. Of these, 68 showed tissue, 12 mucositis, diagnosed peri‐implantitis. Peri‐implant measured mesially distally at the implant shoulder using laser Doppler flowmetry tissue spectrophotometry (LDF‐TS), followed a evaluation, including measurement probing depths, bleeding on (BOP), plaque index, biotype, type implant, restoration presence keratinized tissue. Perfusion compared between based conventional BOP–based diagnosis peri‐implantitis, associations values measurements analyzed. Optimal cut‐off for predicting peri‐implantitis calculated receiver operating characteristics. Results mean relative amount hemoglobin blood flow significantly different mucositis ( p = 0.003 0.002, respectively). However, there are interindividual differences that appear influence as well. When linear mixed regression model applied, patient random variable, difference no longer statistically significant 0.400). Still, optimal value determined be > 46.5 AU (AUC 0.788; < 0.001; CI 0.695–0.881; sensitivity 1.00, specificity 0.60). Conclusion Implants flaps particularly vulnerable disease. Risk factors lack fixed restorations, bone‐level implants, high levels. As noninvasive objective method, LDF‐TS can contribute risk assessment evaluating help detect early onset

Abstract Objective The objective of this study is to evaluate a compact ultrasound transducer image anatomical biomarkers for periodontal diagnosis teeth, including difficult-to-reach posterior teeth. Materials and methods A 9-MHz hockey-stick was used 53 premolars, 30 molars, 79 incisors canines from 13 subjects. alveolar bone crest (ABC), cementoenamel junction (CEJ), gingival margin (GM) were identified by imaging. image-based distances between these anatomic landmarks measured iABC (ABC CEJ), iGR (GM CEJ) iGH GM). measurements compared corresponding parameters obtained clinical examination. also assess health with diagnosis. Results average − 1.12 mm (i.e., above the gingivitis Stage I periodontitis, 0.56 III demonstrating significant increase in recession patients severe periodontitis (Student t-test, unpaired, two-tailed, p < 0.0001). distinguished gingivitis, group, group (unpaired, two-tailed 0.05 PPD, = iGH). Conclusion Non-invasive imaging can be stratify subjects differing disease severity. are reproducible. Clinical relevance as screening tool affected examination treatment.
