MATERIAL AND METHODS: Twenty-nine patients diagnosed with Stage III or IV periodontitis were enrolled in this single-blind, split-mouth, randomized controlled trial (RCT). Quadrants were randomly assigned to receive either ultrasonic subgingival debridement alone (SD group) or ultrasonic subgingival debridement followed by manual root planing (SRP group). Clinical parameters, including Probing Pocket Depth (PPD), Clinical Attachment Level (CAL), and Bleeding Index (BI), were recorded at baseline, 3, and 6 months. RESULTS: Twenty-nine patients completed the study. Both treatment modalities yielded statistically significant improvements in all clinical parameters compared with baseline (p < 0.05). The SRP group resulted in superior outcomes compared with ultrasonic subgingival debridement alone. Analysis revealed a significantly greater PPD reduction in the SRP group at 3 months (adjusted MD: 0.20 mm; 95% CI [0.13, 0.27]; p < 0.01), and this advantage was sustained at 6 months (adjusted MD: 0.11 mm; 95% CI [0.05, 0.18]; p < 0.01). SRP achieved superior CAL gain at 3 months (adjusted MD: 0.10 mm; 95% CI [0.01, 0.19]; p < 0.05). Crucially, regarding clinical endpoints, the SRP group exhibited a significantly lower prevalence of residual deep pockets (PPD ≥ 5 mm) at 3 months and 6 months compared with the SD group (p < 0.05), indicating a higher rate of pocket closure. Both treatment modalities achieved significant reductions in Bleeding Index (BI) scores compared to baseline (p < 0.05), with no statistically significant inter-group differences observed at any time point. CONCLUSIONS: While ultrasonic debridement alone is effective, the adjunctive use of manual root planing yields statistically significant, though modest, additional benefit in PPD reduction and CAL gain in generalized severe periodontitis. While it effectively reduces the burden of residual pockets in the short term, its long-term advantage is attenuated, highlighting the necessity of strict supportive periodontal therapy. </p>","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13248239/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147769942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has a positive psychological effect on patients and makes it easier to adapt them later to a complete denture. PURPOSE: Aim of the present study was to investigate the survival rate and need for maintenance of cover-denture prostheses. METHODS: Data were collected from patient records. Statistical analysis was performed using Kaplan-Meier survival analyses, log-rank tests (P < 0.05), Cox regressions (P < 0.05), and Non-Parametric Mean Cumulative Function. RESULTS: Two hundred twenty-seven cover-dentures in 204 patients were examined. Mean age was 67 years, mean follow-up time was 3.4 years. 27.75% of prostheses were borne on one abutment tooth, 40.97% on two and 31.28% on three abutment teeth. In 60.4% percent of cases, copings were cast from a precious alloy. The 5-year survival rate for cover-dentures was 64.5%. The most common complication (36.6%) was decementation of a coping. In 30.9% of cases, one or more abutment teeth fractured and in 28.7% of cases one or more abutment teeth were lost. Most common need for maintenance was the removal of pressure points in the prosthesis. In 29.5% of cases, a relining of the cover-dentures was necessary. CONCLUSION: A cover-denture prosthesis is a suitable therapeutical option for patients with few remaining teeth. The survival rate is comparable to that of other double crown retained removable partial dentures and occurring complications are manageable. Cover-denture prostheses represent an adequate alternative to complete extraction and can be recommended in clinical practice. </p>","PeriodicalId":12994,"journal":{"name":"Head & Face Medicine","volume":"22 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13104299/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147769884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS: This retrospective study included 191 OSA patients who underwent UPPP. Postoperative outcomes were assessed at a three-month follow-up, and a multivariate logistic regression model combining body mass index (BMI), apnea–hypopnea index (AHI), peripheral blood oxygen saturation (SpO₂), Epworth Sleepiness Scale (ESS) score, visual analogue scale (VAS) score, and Friedman staging was constructed to predict surgical efficacy.

RESULTS: WT is by far the most common benign tumor of the parotid gland, followed by PA and the age of diagnosis shows an increasing tendency. The hospitalization time showed a significant reduction after a period of ten years. Patients treated with ED are being hospitalized for a shorter period of time. Regular smokers tend to present more WT and are being diagnosed at younger age. Patients with WT have a higher body mass index (BMI) than other patients.
