Title: Perceptions of shared decision-making among patients and dental professionals Authors: Jung, Ji-Young; Ko, Kyung-A; Park, Yu An; Chi, Christina; Naenni, Nadja; Lee, Jung-Seok Abstract: Objectives: To compare perceptions of shared decision-making (SDM) among patients, dentists, and dental hygienists participating in the same dental treatment-planning encounter and to examine differences in perceived involvement across SDM components. Methods: A cross-sectional questionnaire study was conducted at a university dental hospital and included 60 dentists, 30 dental hygienists, and 180 patients. Perceived SDM involvement was assessed using the validated Korean versions of the 9-item Shared Decision Making Questionnaire (SDM-Q-9) for patients and the Shared Decision Making Questionnaire-Physician Version (SDM-Q-Doc) for dental professionals. Responses were recorded on a 6-point Likert scale and transformed to a 0-100 scale, with higher scores indicating greater perceived involvement. Group differences and factors associated with SDM scores were analyzed using one-way analysis of variance and linear regression models, respectively. Results: A total of 270 participants completed the survey. SDM scores were high across groups, ranging from 72 to 84 of 100. Patients reported significantly higher total SDM scores than dentists and dental hygienists. Across all respondent groups, recognition that a decision needed to be made and agreement on how to proceed received the highest ratings. In contrast, weighing treatment options was consistently rated lowest. Conclusions: The need for a decision and agreement on the final decision were rated most positively across all groups. However, variation across specific components, particularly the weighing of treatment options, indicates the need for a more structured approach to enhance patient understanding and integrate patient preferences in routine dental care. Clinical significance: Differences in shared decision-making perceptions between patients and dental professionals highlight the importance of reflecting on clinical communication. Strengthening structured decision-making processes may enhance patient-centered care in dentistry.

Title: Patient regret in tooth extraction for periodontitis: Highlighting the role of patient involvement in decision-making Authors: Ko, Kyung-A; Jung, Ji-Young; Ko, Youngkyung; Muller, Nicolas P. A.; Kim, Junhewk; Lee, Jung-Seok Abstract: Background Tooth extraction is one of the most common irreversible treatment options in dentistry, and it may lead to complex emotional responses such as patient regret. This study aimed to assess the extent of decisional regret among patients who underwent tooth extraction due to periodontal disease and to identify associated influencing factors.Methods A total of 104 patients diagnosed with periodontitis and who had experienced tooth extraction participated in this self-administered survey. The questionnaire included the validated Decision Regret Scale (DRS), along with items on demographics, treatment characteristics, and decision-making processes. Linear regression analyses were conducted to identify significant associations.Results The mean DRS score in this study was 26.3 +/- 16.7, which exceeds the commonly used clinical cut-off of 25 and indicates a moderate to high level of regret. Greater regret was significantly associated with dissatisfaction regarding outcomes, perceived inappropriateness of the decision, and a lack of consideration of alternatives. Conversely, greater patient involvement in decision-making was linked with lower regret compared with when decisions were primarily made by the dentist.Conclusion These findings suggest that decisional regret after tooth extraction for periodontitis is more common than previously reported in other medical fields and is influenced by how treatment decisions are made. Patient-centered decision-making may help to reduce regret and to improve patient-reported outcomes in periodontal care.Plain Language Summary When patients have experienced tooth extraction due to gum disease, some may later feel regret about their decision. This study examined 104 adults who underwent tooth extraction because of periodontitis and found a moderate level of decisional regret. Higher regret scores were associated with situations in which the outcome did not match expectations or when patients perceived that they had little role in making the treatment choice. In contrast, lower regret scores were associated with greater patient involvement in decision-making. About 89% of patients were unaware of alternative treatment options when making their extraction decision, revealing a significant gap in how thoroughly options are discussed. The degree of regret observed was similar to that in serious medical decisions such as cancer or heart disease care, suggesting that tooth loss carries meaningful emotional weight for patients. When patients shared the decision-making process equally with their dentist, or made the decision themselves, they experienced significantly less regret. These findings highlight the importance of involving patients as active partners in treatment decisions. Aligning care with patients' values and ensuring that patients understand available options may help to support lower decisional regret and improved patient experiences.

Title: Soft Tissue Volume Augmentation at Single Implant Sites Applying Collagen Matrices or Connective Tissue Grafts: 10-Year Follow-Up of a Randomized Controlled Trial Authors: Strauss, Franz J.; Liguori, Margherita G.; Gasser, Thomas J. W.; Naenni, Nadja; Jung, Ronald E.; Thoma, Daniel S. Abstract: Aim To compare up to 10 years clinical, profilometric and patient-reported outcomes of implant sites previously augmented using a volume-stable collagen matrix (VCMX) or connective tissue graft (SCTG) in the aesthetic zone.Methods The original non-inferiority randomized controlled trial (RCT) enrolled 20 patients who received soft tissue volume augmentation with VCMX or SCTG at single implant sites. Clinical assessments and standardized measurements were performed at baseline after crown insertion and at 6 months, 1, 3, 5, 7.5, and 10 years. The primary outcome was mucosal thickness. Secondary outcomes included marginal bone levels (MBL), probing depth (PD), bleeding on probing (BOP), plaque control record, Pink Aesthetic Score (PES), OHIP-14 and buccal profilometric changes. Group comparisons were performed using mixed-effects and generalized estimating equation (GEE) models, which account for within-patient correlations due to repeated measurements and allow inclusion of all available data without requiring imputation for missing observations.Results Of the 20 originally enrolled patients, 10 (5 in the SCTG group and 5 in the VCMX group) were available for re-examination at 10 years. The adjusted between-group difference in mucosal thickness was -0.02 mm (95% CI -0.99 to 0.96). As the lower bound of the confidence interval remained above the prespecified non-inferiority margin of -1 mm, non-inferiority of VCMX was shown. Buccal contour changes were comparable during the early follow-up, while a trend toward a greater long-term contour decrease was observed in group VCMX (-0.31 mm [95% CI, -0.65 to 0.03]; p = 0.07). Mean PES values were 10.6 in the SCTG group and 9.6 in the VCMX group, with no significant between-group differences (p = 0.45). Both groups revealed high levels of oral health-related quality of life, with low median OHIP-14 scores (SCTG, 0.0; VCMX, 1.0; p = 0.26).Conclusion These preliminary long-term findings showed no clinically relevant differences between SCTG and VCMX in terms of clinical, profilometric and patient-reported outcomes. While SCTG remains the reference standard, VCMX represents a less invasive alternative but with a slight tendency toward greater long-term contour reduction.Clinical Significance Volume-stable collagen matrices serve as a viable alternative to autogenous connective tissue grafts for peri-implant soft tissue volume augmentation, particularly in patients seeking a reduced morbidity, without compromising long-term clinical or aesthetic outcomes.

Title: Advancing the diagnosis of peri-implant diseases: From histological foundations to next-generation ultrasonographic diagnostic markers Authors: Galarraga-Vinueza, Maria Elisa; Cha, Jae-Kook; Tavelli, Lorenzo; Feres, Magda Abstract: Background This critical review provides a comprehensive analysis of the histological foundations, current clinical diagnostic standards, and emerging ultrasonographic methods for diagnosing peri-implant diseases.Methods An electronic search in Medline (PubMed) database was conducted to identify original and review articles focused on the histological foundation and diagnostic approaches of peri-implant diseases. This review provides an integrated perspective on the evolution of peri-implant diseases diagnostics, focusing on the clinical and radiographic criteria established by the latest consensus guidelines. It outlines the histological features of peri-implant diseases and discusses recent advancements in ultrasonographic imaging approaches for their characterization and diagnosis. This review further explores elements such as peri-implant anatomical landmarks, echo intensity, tissue perfusion, and strain elastography.Results Histological studies have defined the peri-implant mucosal architecture and inflammatory patterns characteristic of disease progression. While conventional diagnostics have relied on clinical examination and radiographic imaging, high-frequency ultrasound (HFUS) has recently emerged as a promising noninvasive imaging tool enabling detailed assessment of peri-implant tissue dimensions, echo intensity, vascular perfusion, and the extent of inflammatory involvement. Echo intensity mapping aids in the visualization and quantification of peri-implant lesions and the identification of associated bone defects. These imaging advancements not only complement current diagnostic methods but also deepen our understanding of peri-implant disease dynamics. Observed correlations between histological findings and ultrasonographic features can support the development of a new diagnostic framework incorporating HFUS-derived markers for detecting peri-implant lesions and evaluating the severity of inflammation.Conclusions Integrating HFUS and power Doppler imaging into peri-implant diagnostics allows real-time, noninvasive visualization of key structures such as the supracrestal adherent connective tissue, buccal bone levels, and tissue perfusion. These modalities can complement existing standards and enhance diagnostic precision by identifying the extent of peri-implant lesions and quantifying the severity of inflammation.Plain Language Summary Peri-implant diseases can affect the tissues around dental implants and can lead to inflammation and bone loss. Understanding how these diseases develop and how best to diagnose them is essential for improving patient care. The present narrative review looked at scientific studies that examined the tissues around implants and the methods used to diagnose peri-implant diseases. It explains what researchers have learned from tissue (histological) studies and summarizes the current clinical and X-ray based diagnostic standards. It also highlights new advances in high-frequency ultrasound (HFUS), a technology that can provide detailed, real-time images of the soft tissues and bone around implants without radiation. Recent studies show that HFUS can measure tissue thickness, detect inflammation, visualize blood flow, and help identify early bone defects. These ultrasound features match what is known from histology, suggesting that HFUS could become an important tool for detecting peri-implant disease earlier and more accurately. Overall, adding HFUS and power Doppler imaging to current diagnostic methods can improve the evaluation of peri-implant tissues. These noninvasive techniques can help clinicians see key structures more clearly, assess inflammation, and better understand the severity of the disease.
