Management of Demented Patients in Emergency Department
Full text linkThe hospitalization of the elderly with acute illness is one of the most discussed in the organization of health services, it is not yet clear whether the hospital is really the best response to the needs of the elderly, especially those with cognitive impairment. Despite evidence of possible adverse effects of hospitalization (immobilization, acute confusional state resulting in sedation, risk of falls, intestinal sub-ileus), there has been an increasing use of the hospital, particularly to specialist services. Regardless of the benefits from the shelter (instrumental diagnosis and prompt treatment of acute somatic disease), in people with dementia it needs to identify the characteristics of the person (cognitive impairment, functional status, somatic comorbidity, social and familial status), the personal needs and, therefore, diagnostic and therapeutic targets which must be assumed for that sick person during hospitalization. To this end, it is fundamental the role of assessment and diagnostic orientation that takes place in the Department of Emergency and Acceptance (DEA), which mainly receives patients at the hospital. Even before the hospital recovery it is therefore essential to check how many elderly patients with cognitive impairment that belong to the DEA, and what are their needs.</jats:p

No full textIn-vitro comparison of toothbrush bristles penetration into the peri-implant sulcus
No full textBackground: Implant-prosthetic reconstructions present anatomical and structural characteristics different from the dento-periodontal condition. These differences can lead to a problematic hygienic access by toothbrush bristles and a consequently reduced biofilm removal.
Aim/Hypothesis: The aim of this preclinical study was to compare the ability of the conical and cylindrical bristles to penetrate the peri-implant sulcus.
Material and Methods: A mandibular dentition was reproduced using a plaster model: the gingival component was recreated in silicone and a glass cylinder was positioned simulating a 4 mm diameter implant. The penetration of the bristles during brushing was recorded by using an optical fiber placed inside the cylinder. The Bass Technique was performed in a humid environment from the vestibular side. This brushing motion is described as a vibratory movement of the bristles oriented at 45° respect to the long axis of the tooth into the sulcus. The protocol included 5 toothbrushes per group and 10 tests per toothbrush, for a total of 50 assessments for each of the two groups. Each test lasted 1 minute with controlled pressure of approximately 350gr and a stroke length of 25 mm. Five degrees of penetration were identified: grade 0 (<2 mm), grade 1 (2–3 mm), grade 2 (3–4 mm), grade 3 (4–5 mm) and grade 4 (5–8 mm). The highest value was collected for each test.
Results: The conical bristles showed 8 times greater efficacy (P = 0.001) than the cylindrical bristles (multilevel analysis). The percentage of tests reaching depths ≥3 mm was 86% for conical group and 28% for the cylindrical group.
Conclusion and Clinical implications: This preclinical study shows a clear and superior penetration capacity of the conical bristles compared to traditional cylindrical ones. Further studies are required to investigate the correlation between penetrative capacity and cleaning efficacy in implant conditions. If a greater penetrative capacity is correlated with a greater cleaning efficacy, then these newly designed bristles would be preferable
In vitro comparison of two types of toothbrush bristles in penetration capacity into the peri- implant sulcus.
No full textAim: The aim of this preclinical study was to compare the ability of the conical and cylindrical bristles to penetrate the peri-implant sulcus.
Methods: A mandibular dentition was reproduced using a plaster model. The gingival component was recreated in silicone and a glass cylinder simulating a 4mm diameter implant was positioned by replacing element # 3.6. Using an 1mm diameter optical fiber placed from the lingual side inside the cylinder, the penetration of the bristles was recorded during the brushing. The Bass Technique was performed in a humid environment from the vestibular side. This brushing motion is described as a vibratory movement of the bristles arranged at 45° respect to the long axis of the tooth into the sulcus. The protocol included 5 toothbrushes per group and 10 tests per toothbrush for a total of 50 assessments per group. Each test lasted 1 minute with controlled pressure of approximately 500gr and a stroke length of 15 mm. From the video clips acquired, 4 degrees of penetration were identified: grade 0 (<2mm), grade 1 (2-3mm), grade 2 (3-4mm), grade 3 (4-5mm) and grade 4 (5-8mm). The highest value was collected for each test. At an α level of 0.05 for a one-tailed test with a power of 80% and a margin of superiority of 40%, a sample of 10 toothbrushes was needed. Intraoperative variability was assessed with the Cohen's kappa coefficient. A generalized mixed-effect linear model (multilevel analysis) was used considering the level of bristle penetration as the primary outcome and the type of bristle as fixed effects. The level of significance α was a priori set at 0.05. The null hypothesis affirms that no difference of efficacy (level of penetration) exists between the two types of bristles.
Results: Excellent agreement was obtained between the measurement performed by the examiner (K-statistics =1). The conical bristles showed 8 times greater efficacy (p = 0.001) than the cylindrical bristles; moreover, with respect to the latter, the degree of penetration of the conical bristles proved to be 2 times (p = 0.015), 20 times (p = 0.001) and 76 times (p = 0.001) higher than degrees 1, 2 and 3 respectively. The null hypothesis was therefore rejected.
Conclusion: This preclinical study shows a clear and superior penetration capacity of the conical bristles compared to traditional cylindrical ones. This result suggests a greater hygienic efficacy at the peri- implant level for the newly designed bristles
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
In-vitro comparison of two different toothbrush bristles about peri-implant sulcus penetration
Full text linkObjective: The aim of this preclinical study was to compare the ability of tapered and cylindrical bristles to penetrate the peri-implant sulcus. Methods: A full mandibular dental arch was reproduced in plaster cast. In site #3.6 a hollow glass cylinder was positioned simulating a 4 mm diameter implant and the gingival component was recreated by using dedicated silicone. A Bass brushing technique was performed from the vestibular side in humid environment. During it, the penetration of the bristles between the gum and the implant was recorded by mean of an optic fibre fixed inside the cylinder. The protocol included 5 toothbrushes per group and 10 tests per toothbrush, for a total of 50 assessments for each of the two groups. A scale of 5 grades for bristle penetration was defined: grade 0 (× < 2 mm), grade 1 (2 ≤ × < 3 mm), grade 2 (3 ≤ × < 4 mm), grade 3 (4 ≤ × < 5 mm) and grade 4 (5 ≤ × < 8 mm). From the video recordings the highest value of penetration was identified for each test. Results: The tapered bristles showed an 8 times greater penetration capacity (p = 0.001) in respect to the cylindrical bristles (multilevel analysis). The percentage of tests reaching depths ≥3 mm was 86% for tapered group and 28% for the cylindrical group. Conclusion: This preclinical study shows a clear and superior penetration capacity of the tapered bristles in respect to traditional cylindrical ones. For tapered bristles, a potentially greater hygienic efficacy around dental implants is suggested

No full textThe Role of Anxiety on Gingival Recession Occurrence: An Observational Study
No full textAim: The gingival recession is recognized as a clinical manifestation of periodontitis; however, many evidences suggest that an incorrect brushing could be responsible of its occurrence too. Assuming that improper hygiene actions could be responsible of tissues damage and knowing that psychological factors can influence the oral hygiene habit, it could be possible that anxiety relates to gingival recession. This study investigated this potential correlation.Material and Methods: Forty-three consecutive subjects showing at least one buccal recession were selected. Patients were interviewed using special forms to record oral hygiene habits and to define the anxiety level. A complete clinical and radiographic examination was also performed. By using the collected data, the study sample was divided into 2 groups: group A with intact periodontal support except for buccal recessions, and group B with not only buccal signs of attachment loss. Number of recessions and their depth were correlated with hygienic parameters.Results: A positive correlation has been detected between anxiety and plaque index in both groups, a negative one was observed between anxiety and frequency of brushing in group A. A negative correlation between anxiety and gingival recession dimension has been detected only for group A.Conclusions: Adult subjects with high value of anxiety display a worse oral hygiene habit, though this emotional aspect seems to have a protective effect on buccal recession development
PERI-IMPLANT CONDITION AND PROSTHETIC RESIDUAL CEMENT: AN ENDOSCOPICAL EVALUATION
No full textAim. The main objective of this study is to evaluate under endoscopic vision the eventual presence of submucosal residual prosthetic cement (CE) in peri-implant disease cases. The correlation between the pathological condition and the apical position of CE has been also investigated.
Methods. Forty-six patients with clinical and/or radiographic signs of peri- implant disease (mucositis or peri-implantitis) were included. All patients had a definitive cemented prosthesis loaded for at least 3 months. Patients with mucositis were treated with gentle debridement and re-evaluated at one month; if mucositis was resolved the patient was not included in the study. All enrolled patients underwent to endoscopic analysis (DV2 Perioscope) at the implant site, to identify eventual submucosal CE. The proximity of CE to implant platform was measured by means of a periodontal probe (PCP UNC-15) under endoscopic vision.
Results. CE was detected in 37 out of 46 implants (80.4%) and were mainly located at vestibular and lingual or palatal areas. The most apical portion of the CE was located at 1.80mm from the edge of the implant platform. This distance was lower for implants with a diagnosis of peri-implantitis (1.11mm) than in sites with mucositis (2.21mm) (p=0.001).
Conclusion. The presence of CE was strongly associated with peri-implant disease. The proximity of CE to implant platform was correlated to the severity of peri-implant disease
