“…The ultrasound procedures (equipment setup, scanning protocol, etc.) are outlined in previous reports (Barootchi, Chan, et al 2020;Chan and Kripfgans 2020;Tavelli et al 2021) and detailed in the Appendix, with complete descriptions on 3 imaging modalities (Fig. 2).…”

“…Since the power is derived from the integrated phase shift, CP scales with the amount of blood flowing within the ultrasound beam point-spread function, and it is particularly useful for detecting flow in small vessels or low-velocity flow. For higher tissue perfusion, more blood vessels might be active, and the vasculature might show vasodilation; thus, more blood might be flowing (Chan and Kripfgans 2020;Tavelli et al 2021). The images were acquired in "still images" (a single image of the field of view) and "cine loops" (videos generated as a series of consecutive still images at a frame rate of 20 Hz).…”

Color flow ultrasonography has played a crucial role in medicine for its ability to assess dynamic tissue perfusion and blood flow variations as an indicator of a pathologic condition. While this feature of ultrasound is routinely employed in various medical fields, its intraoral application for the assessment of tissue perfusion at diseased versus healthy dental implants has never been explored. We tested the hypothesis that quantified tissue perfusion of power Doppler ultrasonography correlates with the clinically assessed inflammation of dental implants. Specifically, we designed a discordant-matched case-control study in which patients with nonadjacent dental implants with different clinical diagnoses (healthy, peri-implant mucositis, or peri-implantitis) were scanned and analyzed with real-time ultrasonography. Forty-two posterior implants in 21 patients were included. Ultrasound scans were obtained at the implant regions of midbuccal, mesial/distal (averaged as interproximal), and transverse to compute the velocity- and power-weighted color pixel density from color velocity (CV) and color power (CP), respectively. Linear mixed effect models were then used to assess the relationship between the clinical diagnoses and ultrasound CV and CP. Overall, the results strongly suggested that ultrasound’s quantified CV and CP directly correlate with the clinical diagnosis of dental implants at health, peri-implant mucositis, and peri-implantitis. This study showed for the first time that ultrasound color flow can be applicable in the diagnosis of peri-implant disease and can act as a valuable tool for evaluating the degree of clinical inflammation at implant sites.

“…Nonetheless, most of the indices that have been proposed for assessing the aesthetic outcomes of dental implants are based on professional evaluation and not on patients' perspectives (Belser et al, 2009;Juodzbalys & Wang, 2010;Stefanini et al 2018). Among the techniques that have been performed for improving the aesthetic conditions at implant sites, soft tissue augmentation with autogenous grafts or substitutes have shown great outcomes and predictability (Bianchi & Sanfilippo, 2004;Cairo et al, 2017;Tavelli et al, 2021;Zucchelli et al, 2013Zucchelli et al, , 2020. In particular, Hosseini and co-workers evaluated the 5-year tissue changes in the anterior maxilla around implants that were placed with or without a connective tissue graft (CTG) (Hosseini et al, 2020).…”

Objectives To review the available literature on patient‐reported outcome measures (PROMs) following soft tissue augmentation at implant sites. Materials and Methods A comprehensive electronic and manual search was performed to identify clinical studies that involved soft tissue augmentation around dental implants and reported PROMs, including post‐operative morbidity, painkillers intake, quality of life, aesthetics and satisfactions. Results Nineteen articles were included in the qualitative analysis. Autogenous grafts (free gingival graft and connective tissue graft), acellular dermal matrix and xenogeneic collagen matrix were utilized, either with a bilaminar‐ or an apically positioned flap approach. PROMs reported in the literature included perceived hardship of the procedure and pain during the surgery, post‐operative morbidity, painkillers intake, number of days with discomfort, satisfaction, aesthetic evaluation, quality of life and willingness to undergo the treatment again. Most of the included studies showed similar PROMs between autogenous grafts and substitutes, in terms of post‐operative morbidity, painkillers intake, quality of life, aesthetic assessment and satisfaction. Nevertheless, a trend towards lower post‐operative discomfort was observed for graft substitutes. High scores for patient satisfaction and aesthetic evaluation were observed in all the interventions compared to non‐grafted sites. Conclusions PROMs represent a crucial endpoint of clinical studies evaluating the outcomes of soft tissue grafts at implant sites. Most of the studies did not find significant differences in terms of patient morbidity and painkillers between autogenous grafts and substitutes. Soft tissue grafting can enhance patient satisfaction and aesthetic evaluation compared to non‐grafted sites.

“…Imaging technology has recently seen an increase in center frequency and also an increase in point of care solutions, i.e., smaller and more portable systems [27]. This sets the stage for an attempt on the initiation of facilitating ultrasonic imaging with proper spatial resolution, practical scan head size and meaningful clinical applications [28]. These technological advancements could be especially helpful to monitor oral wound healing and evaluate periodontal (gum) and peri-implant tissues longitudinally.…”

The vast majority of clinicians associate diagnostic ultrasound with a tool that is designed for the living patient. However, it is of course possible to apply this imaging technology to evaluate the recently deceased patient for postmortem diagnosis, or even just examine postmortem tissue. We describe several cases in which ultrasound-enabled providers obtain answers in postmortem examinations and discuss potential future strategies and applications. In addition, we will also illustrate the use of sonography in minimally invasive post-mortem tissue sampling (MITS), an approach that can be used in post-mortem minimally invasive autopsies as well as for establishing ultrasound diagnostic parameters in new medical fields such as periodontal and dental implant specialties.
