    In: Journal of Clinical Periodontology, Wiley, Vol. 47, No. 5 ( 2020-05), p. 640-648
    Abstract: To evaluate the effects of (a) transcrestal sinus‐floor elevation (TSFE) and (b) residual bone height on long‐term implant survival. Materials and Methods Chi‐squared and t tests were used for descriptive comparison of the groups. Kaplan–Meier survival curves and corresponding log‐rank tests were used to investigate implant survival over time. Multivariable Cox regressions were performed for the total population and experimental group. Results A total of 634 patients received 648 implants with TSFE, while 674 implants without TSFE served as controls. Thirty implant failures occurred in the experimental group and 28 in the control group. Ten‐year Kaplan–Meier survival curves for the 157 implants (24.3%) still under observation showed a probability of survival of 93.7% for the implants with TSFE and 92.9% for the 72 implants without TSFE ( p  = .678). The probability of 10‐year survival of all implants in the experimental group decreased to 77.4% for implants placed in residual bone heights of 1–3 mm, compared with 95.7% for implant sites with bone heights of 4–6 mm and 97.6% for bone heights of 〉 6 mm. Conclusions Transcrestal sinus‐floor elevation has no negative effect on the long‐term implant survival. Membrane perforation or negligible bone height, however, reduces the probability of 10‐year survival.

    Intra‐ and Interobserver Reliability of Shear Wave Elastography in Breast Cancer Diagnosis
    Wiley ; 2023
    In:  Journal of Ultrasound in Medicine
    Details
    In: Journal of Ultrasound in Medicine, Wiley
    Abstract: Shear wave elastography (SWE) is increasingly used in breast cancer diagnostics. However, large, prospective, multicenter data evaluating the reliability of SWE is missing. We evaluated the intra‐ and interobserver reliability of SWE in patients with breast lesions categorized as BIRADS 3 or 4. Methods We used data of 1288 women at 12 institutions in 7 countries with breast lesions categorized as BIRADS 3 to 4 who underwent conventional B‐mode ultrasound and SWE. 1243 (96.5%) women had three repetitive conventional B‐mode ultrasounds as well as SWE measurements performed by a board‐certified senior physician. 375 of 1288 (29.1%) women received an additional ultrasound examination with B‐mode and SWE by a second physician. Intraclass correlation coefficients (ICC) were calculated to examine intra‐ and interobserver reliability. Results ICC for intraobserver reliability showed an excellent correlation with ICC  〉 0.9, while interobserver reliability was moderate with ICC of 0.7. There were no clinically significant differences in intraobserver reliability when SWE was performed in lesions categorized as BI‐RADS 3 or 4 as well as in histopathologically benign or malignant lesions. Conclusion Reliability of additional SWE was evaluated on a study cohort consisting of 1288 breast lesions categorized as BI‐RADS 3 and 4. SWE shows an excellent intraobserver reliability and a moderate interobserver reliability in the evaluation of solid breast masses.

    Full block or split block?—Comparison of two different autogenous block grafting techniques for alveolar ridge reconstruction
    Wiley ; 2023
    In:  Clinical Implant Dentistry and Related Research
    Details
    In: Clinical Implant Dentistry and Related Research, Wiley
    Abstract: To evaluate radiographic bone gain after alveolar ridge augmentation with two different designs of autogenous block graft harvested from the mandible. Materials and Methods Alveolar ridge defects were evaluated by preoperative cone beam computed tomography (CBCT) and grafted in a staged approach using intraoral block grafts. The ridge augmentation was either performed using the full‐block technique (group 1) or the split‐block technique (cortical plate with autogenous bone chips) (group 2). After 4 months of bone healing, a further CBCT scan was performed before implant placement. Horizontal and vertical bone gain were measured. Results In this retrospective study, 91 patients were grafted with block grafts (36 patients with full‐block grafts; 55 patients with split‐block grafts) resulting in 171 block grafts in total. The mean horizontal bone gain was 3.37 ± 0.71 mm in group 1 and 5.79 ± 2.20 mm in group 2. A linear mixed‐effect model also showed a statistically significant group difference ( p   〈  0.001, estimate: 3.455, 95% CI: [2.082–4.829]). The mean vertical bone gain was 2.85 ± 0.73 mm in group 1 and 7.60 ± 1.87 mm in group 2. A linear mixed‐effect model also showed a statistically significant group difference ( p : 0.029, estimate: 3.126, 95% CI: [0.718–5.557]). Mean marginal bone level was 0.33 ± 0.37 mm (group 1) and 0.17 ± 0.29 mm (group 2). Conclusion The split‐block technique resulted in a greater bone gain than the full‐block technique. This effect was observed in both the vertical and the horizontal dimensions.

    Abstract: OBJECTIVES Surgery of the aortic root in acute aortic dissection type A (AADA) remains a topic of vague evidence since the extend of dissection and surgeons’ capability and interpretation of the disease vary remarkably. We aimed to interpret root operation strategies in the German Registry for Acute Aortic Dissection cohort. METHODS German Registry for Acute Aortic Dissection collected the data of 56 centres between July 2006 and June 2015. A total of 3382 patients undergoing operations for AADA were included and divided into 3 groups according to aortic root procedure types: supracommissural replacement (SCR), conduit replacement (CR) and valve sparing root replacement (VSRR). RESULTS Patients in SCR (2425, 71.7%) were significantly older than CR (681, 20.1%) and VSRR (276, 8.2%) (63.4 vs 57.5 vs 54.2 years; P  & lt; 0.001), more female (38.9% vs 32.0% vs 26.1%; P  & lt; 0.001) and presented with less aortic regurgitation (26.3% vs 57.1% vs 56.5%; P  & lt; 0.001). VSRR presented with slightly less multiple organ malperfusion (11.6% vs 12.0% vs 10.9%; P = 0.045) and were more often diagnosed for Marfan syndrome (2.4% vs 5.1% vs 9.1%; P  & lt; 0.001). Thirty-day mortality was lower for VSRR (11.6%) compared to SCR (16.1%) and CR (19.8%; P = 0.010). Despite longer procedural times, multivariable regression showed no influence of total arch replacement for VSRR on mortality compared to CR (odds ratio 0.264; 95% confidence interval, 0.033–2.117; P = 0.21). CONCLUSIONS SCR remains the procedure of choice in elderly and compromised patients. Extended root preservation techniques may be applied even in combination with extended aortic arch surgery for selected patients for AADA with promising early outcomes.

    Abstract: Fundo: Avaliar as alterações na altura óssea apical / ganho ósseo por até 8 anos após a colocação do implante combinada com elevação simultânea do seio interno do assoalho do seio (ISFE) sem o uso de enxerto. Métodos: 217 implantes foram colocados em combinação com ISFE sem enxerto e integrados com sucesso na maxila posterior de 138 pacientes. As radiografias após a cirurgia ao longo de um período de avaliação de até 8 anos foram analisadas. Alterações na altura óssea apical e marginal relacionadas aos implantes foram medidas. As diferenças na altura óssea ao longo do período do estudo foram avaliadas pelo teste de Wilcoxon. Para identificar possíveis fatores de influência no ganho ósseo apical e perda óssea marginal, foram realizadas seleções de regressão linear regressiva e modelos de regressão linear mista. Resultados: Nos aspectos apicais dos implantes, observou-se ganho ósseo vertical médio significativo de 2,4 mm (mesial) e 2,6 mm (distal) após 6 meses ( p   〈  0,05). A análise radiográfica produziu ganho ósseo adicional de até aproximadamente 3,5 mm durante o período do estudo. A altura óssea inicial pequena foi cruzada com ganho ósseo apical mais pronunciado ( p   〈  0,05). Conclusões: Se os implantes forem colocados combinados com o ISFE sem enxerto, pode-se esperar um ganho ósseo vertical significativo, especialmente no primeiro ano pós-operatório. Menor altura óssea inicial está associada a uma maior probabilidade de maior ganho ósseo.

    Abstract: To develop a German version of the Dental Environment Stress (DES) questionnaire, and to evaluate its reliability and validity. Methods The original English DES questionnaire was translated into German using a forward–backward translation process. To evaluate construct stability, a subgroup of dental students ( n  = 43) completed the DES twice (interval: 1 week). To evaluate how the DES responds to anticipated changes in stress, all dental students' ( n  = 64) DES scores and saliva cortisol levels administered from a clinical study were compared between holiday and term time. Furthermore, the Depression, Anxiety and Stress Scale (DASS) and a stress self‐assessment were used to determine the validity of the DES. Reliability analyses were calculated using Kendall's tau correlations. To estimate reliability strength, correlation coefficients and intraclass correlations (ICCs) were used. Results Regarding construct stability, 24 of 25 DES items had at least moderate correlations, and most items showed strong correlations. Correlations for the seven subdomains were good (range: 0.778–1.000). The same was true for the total DES score (ICC: 0.944). Correlations for response to term‐time stress were weaker and more varied. Validity analyses revealed fair correlations between the DES and students' self‐assessment (Pearson's r  = .592) and DASS score (Pearson's r  = .392), suggesting satisfactory validity. Stress levels were quite similar between baseline and follow‐up. Conclusion The German DES is a reliable tool for evaluating stress in dental students. Because it can be used to identify individual stressors in various categories, it might enable the detection of specific stress situations in educational situations and facilitate solutions (adjustment of curricula, tailored consulting services).

    In: Journal of Esthetic and Restorative Dentistry, Wiley, Vol. 31, No. 6 ( 2019-11), p. 572-582
    Abstract: There is a lack of comprehensive indexes, which can measure conditions or changes in dento‐facial esthetics before and after treatment. Therefore, the 12‐item Dental Esthetic Screening Index (DESI) was developed and validated. Materials and Methods Reliability was tested by five dental professionals, who evaluated 30 standardized patient photographs baseline and after 14 days. Clinical validation was done on 52 patients before and after restorative treatment. For subjective assessment, patients completed a validated questionnaire before and after treatment. Statistical analysis included inter and intrarater reliability, Wilcoxon test and linear regression analysis. Results The single item analysis identified two weak extraoral items (κ = 0.15; κ = −0.05), that were removed from the DESI. After this modification, both inter‐ (κ = 0.83‐0.86) and intrarater reliability (ICC 1‐5 = 0.75‐0.86) were in excellent to good agreement. In the clinical validation, the DESI was significantly lower after restorative treatment ( P   〈  .0001). The patients' perception questionnaires showed significant improvement after restorative therapy ( P   〈  .0001). A correlation of the DESI and the results of patients' perception questionnaires could be assumed ( P   〈  .0001; R 2 = 0.32). Conclusions The DESI was found to be a reliable and valid instrument for the quantitative assessment of dento‐facial esthetics. It correlated well with the subjective assessment of the patients. Clinical Significance This comprehensive index would allow for objective quantification of clinical situations, for reliable baseline and outcome assessment in esthetic dentistry. As patients' esthetic feelings and sensations are subjective, this objective index is also proven to be congruent to patients' individual subjective assessment of dento‐facial esthetics.

    Abstract: To assess changes in apical bone height/bone gain over up to 8 years after implant placement combined with simultaneous internal sinus-floor elevation (ISFE) without use of graft. Methods 217 implants were placed in combination with graft-free ISFE and successfully healed in the posterior maxilla of 138 patients. Radiographs after surgery across an evaluation time of up to 8 years were analyzed. Changes in apical and marginal bone height related to the implants were measured. Differences in bone height over the study period were evaluated by use of Wilcoxon tests. To identify possible influencing factors on apical bone gain and marginal bone loss, backward linear regression variable selections and linear mixed regression models were performed. Results At the apical aspects of the implants, significant mean vertical bone gain of 2.4 mm (mesial) and 2.6 mm (distal) was observed after 6 months ( p   〈  0.05). Radiographic analysis yielded additional bone gain of up to approximately 3.5 mm over the study period. Small initial bone height was crossed with more pronounced apical bone gain ( p   〈  0.05). Conclusions If implants are placed combined with graft-free ISFE, significant vertical bone gain, especially in the first year post-op, can be expected. Smaller initial bone height is associated with a higher likelihood for greater bone gain.
