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: Survival rate and prosthetic complications of short dental implants supporting implant overdentures: A systematic review and meta-analysis Authors: Pachiou, Aspasia; Naka, Olga; Sykara, Maria; Sykaras, Nikitas; Tsirogiannis, Panagiotis; Thoma, Daniel S.; Naenni, Nadja Abstract: Objectives: To evaluate the survival, marginal bone level changes (MBL), prosthetic complications, and patient-reported outcome measures (PROMs) of short dental implants (<8 mm) supporting implant overdentures. Data: Eight studies (3 RCTs, 5 prospective cohorts; 181 patients; 189 short implants) were synthesized. Primary quantitative findings at 1 year: Implant survival: 97.2% (95% CI, 93.1-98.9%; I-2 = 0%). MBL: pooled mean 0.53 mm (95% CI, -0.20 to 1.27; I-2 = 95.8%). Prosthetic complications: predominantly minor; 45.7% of patients experienced >= 1 maintenance event-most commonly matrix/insert replacement (24.7%) and relining (14.0%); overdenture fractures were uncommon (3.1%). PROMs: consistently high satisfaction, but reporting was heterogeneous. Certainty (GRADE): moderate for survival; low to very low for MBL, complications, and PROMs due to heterogeneity and imprecision. Sources: Systematic review and meta-analysis conducted per PRISMA 2020 (PROSPERO CRD420251042692). Databases searched to May 2025: MEDLINE, Embase, and Scopus. Risk of bias assessed with RoB 2 (RCTs) and ROBINS-I V2 (cohorts). Quantitative synthesis used logit transformation with a Hartung-Knapp random-effects model for survival; inverse-variance random-effects model for MBL; and random-effects generalized linear mixed models (RE-GLMM) for complications. PROMs were narratively synthesized. Study selection: Eligibility included randomized controlled trials and prospective clinical studies evaluating short dental implants (<8 mm) supporting overdentures and reporting >= 1 target outcome (survival, MBL, prosthetic complications, PROMs). After screening and full-text assessment, 8 studies met the inclusion criteria and were included in the quantitative and/or qualitative synthesis. Conclusions: Short implants supporting overdentures show high short-term survival, limited bone remodeling, and manageable maintenance demands, supporting their use where vertical bone height is limited. Long-term, adequately powered trials with standardized outcome reporting are needed to establish predictability over time.

Title: Microbial Profiling of Saliva, Oral Rinse, Subgingival Plaque and GCF Reveals Site-Specific Dysbiosis in Periodontitis: A Within-Subject Comparison of 150 Participants Authors: Lee, Ran; Park, Jin-Young; Park, Yuan; Kim, Kyu; Ha, Jong-Won; Lee, Jung-Seok; 김규 Abstract: Aim This study aimed to compare the microbial communities across four oral sample types-saliva, oral rinse, subgingival plaque and gingival crevicular fluid (GCF)-and to identify disease-associated microbiota in periodontitis.Methods Oral samples were collected from 150 adults, each providing four types of samples in the same visit. Saliva (5 mL) and oral rinse (10 mL, 30-s swish) were collected prior to clinical examination. Subgingival plaque was sampled using a curette from the two deepest pockets, followed by GCF collection via 20-s insertion of gingival retraction cords at the same sites. All samples underwent 16S rRNA (V3-V4) sequencing. Site-specific microbial profiles were evaluated across all participants. For disease comparisons, only individuals with clear periodontal status (periodontally healthy, n = 41; stage III/IV periodontitis, n = 43) were included, excluding stage I/II cases (n = 66).Results Saliva and oral rinse formed one microbial cluster; plaque and GCF formed another. Alpha diversity was found increased in disease, except in GCF. Beta diversity showed the most distinct disease-related shift in GCF. Red complex pathogens and GCF-specific differentially abundant taxa were markedly enriched in periodontitis.Conclusions GCF yielded the clearest microbial differentiation between health and periodontitis, supporting its diagnostic utility.

Implantoplasty vs. Rotating Titanium Brushes in the Surgical Treatment of Peri-Implantitis: A 1-Year Randomised Controlled Clinical Trial

Title: Implantoplasty vs. Rotating Titanium Brushes in the Surgical Treatment of Peri-Implantitis: A 1-Year Randomised Controlled Clinical Trial Authors: Park, Seung-Hyun; Kim, Dong-Beom; Kim, Da-Mi; Sanz-Martin, Ignacio; Sanz-Sanchez, Ignacio; Derks, Jan; Cha, Jae-Kook Abstract: Aim To evaluate treatment outcomes following implantoplasty or the use of rotating titanium brushes in the surgical therapy of peri-implantitis. Materials and Methods Thirty patients with peri-implantitis in need of surgical treatment were enrolled in a 12-month randomised clinical trial with a non-inferiority set-up. Surface decontamination was performed using either titanium brushes (test group) or implantoplasty (control group). Clinical and radiographic parameters as well as patient-reported outcomes (Oral Health Impact Profile-14; OHIP-14) were evaluated. Results At 12 months, the composite outcome was achieved in 6/15 implants in the test group and in 4/15 in the control group. Probing pocket depth (PPD) values decreased by 3.6 +/- 1.5 mm (test) and 3.3 +/- 1.2 mm (control), demonstrating non-inferiority of the test procedure. Additional bone loss was observed in the control group (0.7 +/- 1.2 mm), while bone levels remained unchanged in the test group (0.0 +/- 0.6 mm). Baseline PPD (p = 0.044) and the presence of an adjacent implant affected by peri-implantitis (p = 0.033) were relevant factors for pocket closure (PPD <= 5 mm at 12 months). Time for surface decontamination was significantly less in the test (3 min 1 s) when compared to the control group (5 min 27 s) (p = 0.006). OHIP-14 scores were statistically indifferent. Conclusion Both groups showed favourable outcomes, demonstrating non-inferiority of titanium brushes to implantoplasty.
