Background and Objective
Traditional and planimetric plaque indices rely on plaque-disclosing agents and cannot quantify three-dimensional (3D) structures of dental biofilms. We introduce a novel computer-assisted method for evaluating and visualising plaque volume using intraoral scans (IOSs).
Materials and Methods
This was a 4-day, non-brushing, plaque-regrowth study (n = 15). All plaque was removed at baseline (T0). IOSs at T0 and after 4 days (T4) were used for volumetric plaque assessment in six steps: model acquisition, model superimposition, computer-aided determination of tooth-surface margins, tooth-surface superimposition, visualisation and volumetric evaluation of biofilms. Plaque formation at T4 was additionally assessed with the Turesky Modification of the Quigley–Hein Plaque Index (TMQHPlI). We used Pearson's correlation coefficients and multilevel models to investigate the relationships between TMQHPlI, volumetric plaque index (VPI) and the adjusted volumetric plaque index (AVPI, plaque volume/area).
Results
VPI and AVPI positively correlated with the TMQHPlI, showing higher variability at lower TMQHPlI scores. VPI had a lower threshold for plaque detection and higher sensitivity than the TMQHPlI. VPI and TMQHPlI were highest on vestibular, maxillary and molar surfaces.
Conclusion
VPI quantifies biofilm deposits, is a more precise measure for plaque detection than the TMQHPlI and can be visualised using colour-coded maps displaying areas of equal plaque thickness.

Aim
To investigate the functional significance of mitophagy in age-related osteogenic decline and the underlying mechanisms using in vivo and in vitro models.
Materials and Methods
An alveolar bone defect model in aged mice and a serial passaging–induced ageing model of human periodontal ligament stem cells (PDLSCs) were established. Osteogenic potential in mice was assessed by micro-CT, immunofluorescence, immunohistochemical analyses and histological staining. Osteogenic differentiation, mitochondrial function and mitophagy in PDLSCs were assessed using molecular techniques, cytochemical assays and imaging approaches. HDAC2–Parkin interactions and Parkin acetylation status were examined by mass spectrometry and immunoprecipitation to uncover key mechanisms.
Results
Senescent PDLSCs exhibited impaired mitophagy and osteogenic capacity. Enhancing mitophagy restored osteogenesis of senescent PDLSCs and bone regeneration in aged mice. Mechanistically, HDAC2-mediated deacetylation of Parkin suppressed mitophagy and osteogenesis during ageing.
Conclusion
Activation of mitophagy reverses age-associated declines in osteogenic function, highlighting mitophagy as a therapeutic target for enhancing bone repair in the ageing population.

Aim
To characterise periodontal and faecal microbiomes of individuals with periodontal health (PH) and diseases, and evaluate associations with periodontal, sociodemographic, anthropometric, nutritional and lifestyle factors.
Materials and Methods
Dental biofilm and faecal samples from individuals (n = 24/group) with PH, gingivitis (GG) and periodontitis (PE) were sequenced (16S rRNA). Anthropometric data and questionnaires on demographics, lifestyle, diet and intestinal habits were collected. Data were statistically analysed (p < 0.05).
Results
GG and PE groups showed higher age, BMI, waist/abdominal circumferences and trans-fat intake and lower selenium and vitamin E intake compared to PH. Individuals with PE had higher hip circumference and lower income, education and intake of iron as well as vitamins A and B9. PE microbiomes (oral and faecal) showed distinct compositions, with the highest number of unique oral species. Faecal richness was lower in PE and GG compared to PH. Specific microbial taxa correlated with periodontal status and host factors.
Conclusion
Periodontal and faecal microbiomes vary across periodontal conditions. Discriminant analysis classified 77% of individuals by periodontal status, with key markers for PE including older age, poor dietary quality and distinct microbial oral and faecal signatures. These findings highlight the role of clinical, dietary and microbial factors in periodontal disease profiling.

Background and Objective
Periodontitis is a chronic inflammatory disease driven by immune dysfunction and microbial imbalance. This study aims to identify circulating druggable proteins causally linked to the disease.
Materials and Methods
We integrated proteomics data from deCODE genetics with periodontitis genome-wide association studies (GWAS) from the Million Veteran Program to identify proteins associated with periodontitis. Findings were replicated using GWAS data from the Gene-Lifestyle Interactions in Dental Endpoints consortium. Causal associations were validated using genetic and statistical methods, and the identified proteins were assessed for biological relevance and druggability.
Results
Among the 2088 evaluated proteins, three showed robust evidence of causal association with periodontitis: FGF2 (fibroblast growth factor 2) (odds ratio [OR]: 1.06, 95% confidence interval [CI] 1.032–1.082), AZGP1 (zinc-alpha-2-glycoprotein) (OR: 1.12, 95% CI 1.058–1.189) and BTC (betacellulin) (OR: 0.86, 95% CI 0.789–0.942). Replication analysis confirmed associations for 18 proteins, with 16 showing high colocalisation. Further evaluation of drug target databases revealed indirect links between the identified proteins and approved therapies for inflammatory conditions, suggesting potential therapeutic relevance.
Conclusion
This study identifies three circulating proteins—FGF2, AZGP1 and BTC—as causally associated with periodontitis, highlighting their potential as therapeutic targets. These results provide a foundation for future research into targeted therapies for periodontitis.

Aim
To describe the oral characteristics and evaluate the oral health status of patients with PTEN hamartoma tumour syndrome (PHTS).
Materials and Methods
This descriptive cross-sectional study enrolled participants diagnosed with PHTS at Haukeland University Hospital, Bergen, Norway. A comprehensive oral investigation was performed, including clinical dental and periodontal examination, assessments of gingival overgrowth and palate architecture, intraoral radiographs, orthopantomogram and intraoral optical scanning.
Results
Twenty PHTS patients (13 females), with a median age of 45 years, participated in the study. A median of 25.5 teeth were present, and a DMFT score of 17 and DMFS score of 58 were recorded. Eleven patients (55%) were diagnosed with periodontitis, with seven classified as stage II, grade B, and four as stage IV, grade C. Nineteen patients (95%) had gingival overgrowth; the median clinical and photographic gingival overgrowth score was 2.0 and 40%, respectively, with 45% of the patients requiring treatment for the condition. Mucosal lesions were a universal finding. Palate height index was 52.0. Eight patients had 13 cancer diagnoses in total.
Conclusion
PHTS patients face significant oral health challenges, including compromised dental and periodontal health, prevalent gingival overgrowth, mucosal lesions and a high-arched palate. The findings highlight oral features that may facilitate early recognition of PHTS and reinforce the importance of integrating oral health care into patient management.

<div> <section> <h3> Aim</h3> <p>This study investigates the association between periodontitis and anxiety, focusing on the role of the chemokine CCL2 in mediating this relationship.</p> </section> <section> <h3> Materials and Methods</h3> <p>This study comprises an analytical cross-sectional study and a preclinical in vivo study. In the analytical cross-sectional study, anxiety levels were assessed in individuals with periodontitis and healthy controls using the Hamilton Anxiety Rating Scale (HAMA). Blood and periodontal tissue samples were analysed for CCL2 levels via ELISA and monocyte counts via flow cytometry. In the preclinical in vivo study, a mouse model of ligature-induced periodontitis was established. Anxiety-like behaviours were evaluated using the Open Field Test and Elevated Plus Maze. Blood as well as periodontal and brain tissues were collected to measure CCL2 levels and monocyte/macrophage infiltration through ELISA and flow cytometry. Tight junction proteins in periodontal tissues and brain microvessels were analysed via Western blotting and immunofluorescence. Blood–brain barrier (BBB) permeability was assessed using Evans Blue extravasation. A CCL2-neutralising antibody was administered to assess its effects on anxiety and periodontal pathology.</p> </section> <section> <h3> Results</h3> <p>In the analytical cross-sectional study (50 individuals with periodontitis and 50 healthy controls), individuals with periodontitis showed higher anxiety levels, correlating with elevated CCL2 levels in blood (56.84 [15.87] pg/mL vs. 19.28 [7.47] pg/mL in controls, <i>p</i> < 0.0001) and periodontal tissues (67.37 [23.10] pg/mL vs. 22.77 [10.21] pg/mL in controls, <i>p</i> < 0.0001), as well as increased monocyte counts (CD14 <sup>+</sup> monocytes in blood: 8.08 [3.01]% vs. 5.28 [1.84]% in controls, <i>p</i> < 0.01). In the preclinical in vivo study (total <i>n</i> = 80 mice, with <i>n</i> = 8 per group in analyses), periodontal inflammation increased CCL2 expression in periodontal tissues (125.80 [55.10] pg/mL vs. 25.13 [4.89] pg/mL in controls, <i>p</i> < 0.001) and blood (111.10 [47.80] pg/mL vs. 22.21 [5.39] pg/mL in controls, <i>p</i> < 0.001), enhanced monocyte/macrophage infiltration into periodontal tissues (7.75 [1.96]% vs. 4.82 [0.82]% in controls, <i>p</i> < 0.01) and brain (2.78 [0.91]% vs. 1.38 [0.47]% in controls, <i>p</i> < 0.01), disrupted the integrity of periodontal tight junction and blood–brain barrier and increased anxiety-like behaviours.

Aim
To assess buccal vertical bone resorption following implant placement in healed sites with varying buccal bone wall thicknesses.
Materials and Methods
In 11 miniature pigs, three tapered hybrid titanium implants were placed per hemi-maxilla in healed bone. Sites were randomised into three groups based on buccal bone wall thickness: G1 (< 1.0 mm), G2 (1.0–1.5 mm) and G3 (> 1.5 mm). Animals were euthanised at 24 h and 2, 4 or 8 weeks. Histological and histometric analyses were performed. The primary outcome was the vertical distance from the transition point (TP) between the machined and moderately rough implant surfaces to the first bone-to-implant contact (fBIC).
Results
Healing was uneventful. At 2 weeks, all groups showed buccal resorption, although G3 exhibited earlier bone apposition and fewer resorptive signs. By 8 weeks, all G1 implants displayed exposure of the moderately rough surface, while only one implant in G3 showed exposure. TP-fBIC values at 8 weeks were 0.92 ± 0.63 mm (G1), 0.27 ± 0.54 mm (G2, p = 0.041) and −0.16 ± 0.17 mm (G3, p = 0.0002). Bone-to-implant contact increased over time across all groups.
Conclusion
Thin buccal bone walls (< 1 mm) were associated with greater vertical bone loss and implant surface exposure, whereas thick walls (> 1.5 mm) preserved the buccal bone better and protected the implant surface.
目的探讨不同颊骨壁厚度愈合部位种植体植入后的颊垂直骨吸收情况。材料与方法在11头小型猪的半颌愈合骨中植入3个锥形杂交钛种植体。根据颊骨壁厚度随机分为三组：G1 （1.0 mm）、G2 （1.0 - 1.5 mm）和G3 （1.5 mm）。动物分别于24小时、2周、4周和8周实施安乐死。进行组织学和组织计量学分析。主要结果是从加工过的和中等粗糙的种植体表面之间的过渡点（TP）到第一个骨-种植体接触（fBIC）的垂直距离。结果愈合过程平稳。2周时，所有组均出现口腔吸收，但G3组表现出更早的骨附着和更少的吸收征象。8周时，G1组所有种植体表面均出现中等粗糙暴露，G3组只有1个种植体表面出现暴露。8周时TP‐fBIC值分别为0.92±0.63 mm （G1）、0.27±0.54 mm （G2, p = 0.041）和- 0.16±0.17 mm （G3, p = 0.0002）。骨与种植体的接触随着时间的推移而增加。结论较薄的颊骨壁（1 mm）有较大的垂直骨丢失和种植体表面暴露，而厚的颊骨壁（1.5 mm）能较好地保留颊骨并保护种植体表面。

To evaluate the clinical outcomes of collagen sponges (CSs) on wound healing following palatal graft harvesting and compare their efficacy with gelatine sponges (GSs).
Materials and Methods
Thirty-two participants who had undergone free gingival grafts or de-epithelialised gingival grafts were randomised into the CS group or the GS group. Wound healing rate was calculated as the percentage of the healed wound area divided by the initial wound area. Wound healing rate and complete epithelialisation were evaluated at 1, 2, 3 and 4 weeks. Postoperative pain was assessed on days 1, 3 and 7. Willingness to repeat graft harvesting, delayed bleeding and aesthetic outcomes were also recorded.
Results
CS group had higher wound healing rates than GS group at 1 and 2 weeks (24.44% ± 6.28% vs. 5.56% ± 2.19%, p < 0.01; 91.54% ± 3.20% vs. 75.56% ± 4.77%, p < 0.05). Complete epithelialisation was achieved within 2–3 weeks in CS group and within 2–4 weeks in GS group, but no significant difference was found. Postoperative pain in VAS was lower in the CS group on Day 1 compared with the GS group (1.6 ± 0.4 vs. 3.1 ± 0.5, p < 0.05). No significant difference could be detected in willingness to repeat graft harvesting, delayed bleeding and aesthetic outcomes.
Conclusions
Compared with GS, CS seemed to offer improved early healing and reduced postoperative pain following palatal graft harvesting.

Aim
To evaluate the association between diabetes (types 1 and 2) and peri-implantitis through a register-based cohort study.
Methods
Four groups of individuals with dental implants were identified using multiple Swedish nationwide registers—two groups with diabetes (type 1, T1D; type 2, T2D) and two groups without diabetes (non-T1D, non-T2D). Longitudinal data from 2010 to 2020 were analysed. Peri-implantitis was defined as any registered treatment of peri-implantitis. Prevalence of peri-implantitis (n = 18,975) was evaluated using covariate-adjusted logistic regression analyses. Incidence (n = 2030) was compared using survival analyses across groups matched by age, gender, education, income and the number of implants, through propensity scores.
Results
Peri-implantitis was more frequent among those with T1D compared to non-T1D (21.1% vs. 15.2%; OR 1.46, 95% CI: 1.05–2.04), whereas the prevalence was similar in T2D and non-T2D (20.5% vs. 18.2%; OR 1.06, 95% CI: 0.98–1.16). The hazard ratios for incident peri-implantitis were 1.52 (95% CI: 0.96–2.42) and 1.36 (95% CI: 1.02–1.82) for T1D and T2D, respectively.
Conclusions
T1D and T2D were associated with a higher risk for peri-implantitis. While the elevated risk for peri-implantitis in T1D was particularly apparent in prevalence estimates, the association for T2D was evident mainly in terms of incidence.

Aim
To assess the potential benefit of using adjunct systemic antibiotics in surgical peri-implantitis treatment.
Materials and Methods
Six databases were searched (December 2024) for randomised/non-randomised clinical studies. After duplicate study selection, data extraction and risk-of-bias assessment, random-effects meta-analyses of odds ratios (ORs) or mean differences (MDs) and their 95% confidence intervals (CIs) were performed, followed by the analysis of certainty of evidence.
Results
Seven studies (three randomised and four non-randomised, comprising 595 patients and 1388 implants) were included. Systemic antibiotics were associated with greater short-term treatment success (n = 5; OR = 2.33; 95% CI: 1.29–4.21), bone gain (n = 4; MD = 0.37 mm; 95% CI: –0.68 to –0.07), increased bone level stability (n = 3; OR = 2.73; 95% CI: 1.50–4.99), reduced bleeding on probing (n = 6; OR = 0.49; 95% CI: 0.31–0.78), reduced suppuration on probing (n = 3; OR = 0.33; 95% CI: 0.18–0.61) and increased gingival recession (n = 3; MD = 0.18 mm; 95% CI: 0–0.36 mm) (p < 0.05). Systemic antibiotics seem to benefit only implants with modified surfaces (ORs: modified 4.10 vs. turned 0.79), and event that, without long-term benefits (≥ 3 years). Finally, one trial found that antibiotics probably increased diarrhoea risk.
Conclusions
Evidence from randomised/non-randomised studies seems to indicate that systemic antibiotics benefit surgical peri-implantitis treatment, in the short term (1–2 years), especially for implants with a modified surface, while data on adverse effects is scarce. No substantial long-term benefits are seen (≥ 3 years). Uncertainty still exists regarding the potential benefit of systemic antibiotics as adjunct to surgical management of peri-implantitis.

Systemic antibiotics were associated with greater short-term treatment success (<i>n</i> = 5; OR = 2.33; 95% CI: 1.29–4.21), bone gain (<i>n</i> = 4; MD = 0.37 mm; 95% CI: –0.68 to –0.07), increased bone level stability (<i>n</i> = 3; OR = 2.73; 95% CI: 1.50–4.99), reduced bleeding on probing (<i>n</i> = 6; OR = 0.49; 95% CI: 0.31–0.78), reduced suppuration on probing (<i>n</i> = 3; OR = 0.33; 95% CI: 0.18–0.61) and increased gingival recession (<i>n</i> = 3; MD = 0.18 mm; 95% CI: 0–0.36 mm) (<i>p</i> < 0.05). Systemic antibiotics seem to benefit only implants with modified surfaces (ORs: modified 4.10 vs. turned 0.79), and event that, without long-term benefits (≥ 3 years). Finally, one trial found that antibiotics probably increased diarrhoea risk.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Evidence from randomised/non-randomised studies seems to indicate that systemic antibiotics benefit surgical peri-implantitis treatment, in the short term (1–2 years), especially for implants with a modified surface, while data on adverse effects is scarce. No substantial long-term benefits are seen (≥ 3 years). Uncertainty still exists regarding the potential benefit of systemic antibiotics as adjunct to surgical management of peri-implantitis.</p>\u0000 </section>\u0000 </div>","PeriodicalId":15380,"journal":{"name":"Journal of Clinical Periodontology","volume":"52 12","pages":"1746-1759"},"PeriodicalIF":6.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jcpe.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144915364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
