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

Understanding the available methods to study blood flow in oral cavity can enhance knowledge of research methodology on periodontal circulation related disease initiation and progression as well wound healing. This aims systematically review non-invasive techniques that allow for assessment tissue perfusion clinical pre-clinical studies. A complete electronic literature search 5 databases (NLM PubMed, Embase, EBSCOhost CINAHL, Dentistry Oral Sciences Source, Wiley Cochrane Central Register Controlled Trials) was conducted by two reviewers. The terms included gingival flow, perfusion, imaging soft diagnostic, vascularization, tissue, microvascularization. focused question is: What are quantitative used evaluate perfusion? total 79 articles were qualitative analysis. Various identified, including Laser Doppler Flowmetry (LDF), Speckle Contrast Imaging (LSCI), Spectral Methods (such Diffuse Reflectance Spectroscopy), Ultrasound (US), Intravital Video Microscopy, Videocapillaroscopy. LDF is most applied estimate a small focal area diseases healing, among other indications. LSCI, providing surrogate superficial values 2-dimensional, larger field-of-view, has been similar reasons. use cross-sectional ultrasound rise record velocity volume using color power modes, respectively. Comparisons technologies revealed their strengths limitations spatial resolution, sensitivity, reliability, accuracy, invasiveness, dependence (image) data field view relative probe positioning angulation, safety. ideal features such device pertinent geometry, acquisition, recording, infection control needs also discussed. few have identified cavity. These could potentially augment our ability diagnose monitor healing objectively timely. In combination, these treatment outcomes significantly.
