To evaluate the efficacy of recombinant human platelet-derived growth factor (rhPDGF)-BB combined with a cross-linked collagen matrix (CCM) for treatment multiple adjacent gingival recession type 1 defects (MAGRs) in combination coronally advanced flap (CAF).Thirty patients were enrolled this triple-blind, randomized, placebo-controlled trial and treated either CAF + CCM rhPDGF, or saline. The primary outcome was mean root coverage (mRC) at 6 months. Complete coverage, gain thickness (GT), keratinized tissue width, volumetric ultrasonographic changes, patient-reported measures also assessed. Mixed-modelling regression analyses used statistical comparisons.At months, mRC rhPDGF alone groups 88.25% 77.72%, respectively (p = .02). A significant GT consistently observed both arms, more so receiving containing through time (0.51 vs. 0.80 mm, on average, p .01). presented greater volume gain, higher soft thickness, superior aesthetic score.rhPDGF enhances clinical, volumetric, outcomes MAGRs above results achieved (ClinicalTrials.gov NCT04462237).

Abstract Aim To apply high‐frequency ultrasound (HFUS) echo intensity for characterizing peri‐implant tissues at healthy and diseased sites to investigate the possible ultrasonographic markers of health versus disease. Materials Methods Sixty patients presenting 60 implants diagnosed as ( N = 30) peri‐implantitis were assessed with HFUS. HFUS scans imported into a software where first‐order greyscale outcomes [i.e., mean (EI)] second‐order assessed. Other interest involved vertical extension hypoechoic supracrestal area (HSA), soft‐tissue (STA) buccal bone dehiscence (BBD), among others. Results EI values obtained from soft tissue 122.9 ± 19.7 107.9 24.7 grey levels (GL); p .02, respectively. All showed appearance an HSA that was not present in (area under curve 1). The proportion HSA/STA 37.9% 14.8%. Regression analysis significantly different between (odds ratio 0.97 [95% confidence interval: 0.94–0.99], .019). Conclusions characterization shows significant difference sites. presence/absence may be valid diagnostic discriminate status.

Radiographic examination has been an essential part of the diagnostic workflow in periodontology and implant dentistry. However, radiographic unavoidably involves ionizing radiation its associated risks. Clinicians researchers have invested considerable efforts assessing feasibility capability utilizing nonionizing imaging modalities to replace traditional imaging. Two such extensively evaluated clinical settings, namely, ultrasonography (USG) magnetic resonance (MRI). Another modality, optical coherence tomography (OCT), under investigation more recently. This review aims provide overview literature summarize usage USG, MRI, OCT evaluating health pathology periodontal peri-implant tissues. Clinical studies shown that USG could accurately measure gingival height crestal bone level, classify furcation involvement. Due physical constraints, may be applicable buccal surfaces dentition even with intra-oral probe. also MRI visualize degree soft-tissue inflammation osseous edema, extent loss at involvement sites, level. there was a lack on evaluation tissues by MRI. Moreover, machine is very expensive, occupies much space, requires time than cone-beam computed (CBCT) or intraoral radiographs complete scan. The evaluate remains elucidated, as are only preclinical moment. A major shortcoming it not reach bottom pocket, particularly for inflammatory conditions, due absorption near-infrared light hemoglobin. Until future technological breakthroughs finally overcome limitations OCT, practical routine diagnostics remain plain CBCTs.

Challenging implant esthetic complications are often characterized by malpositioning and interproximal attachment loss of the adjacent teeth. However, limited evidence is available on treatment these conditions. The aim this study was to evaluate clinical, volumetric, patient-reported outcome following peri-implant soft tissue dehiscences (PSTDs) exhibiting teeth, performed through vertical augmentation with submersion.Ten subjects isolated PSTD in anterior maxilla dentition were consecutively enrolled treated horizontal augmentation, involving crown abutment removal, two connective grafts, submerge healing. Clinical outcomes interest included mean coverage, reduction, clinical level (CAL) gain at sites phenotype modifications 1 year. Optical scanning used for assessing volumetric changes. Professional assessment using Implant Dehiscence coverage Esthetic Score (IDES), while involved a 0-10 visual analogue scale.The depth reduction year 2.25 mm, 85.14%, respectively. A keratinized width (KTW) 1.15 mm observed, mucosal thickness (MT) 1.58 mm. CAL 1.45 obtained aspect Greater linear dimensional (LD) changes observed midfacial compared sites. final IDES 6.90 points, evaluation 8.83 points.The present demonstrated that submerged healing an effective approach challenging PSTDs loss. This technique can be resolution most cases, providing substantial levels dentition.
