Keynes' project for an International Clearing Union does not respond only to the economic and political needs of the particular historical moment in which it was conceived, i.e. the establishment of ...an international money really complementary to national currencies. With that project, in fact, Keynes conceives a new kind money, whose positive character is to be un-hoardable. The non-hoardability of the bancor raises the issue of the nature of what is commonly known as 'liquidity', and allows not only to distinguish the liquidity that is proper to money from liquidity in general, but also to refine the concept of liquidity in itself. And finally, it allows to think about the very possibility of other forms of monetary complementarity, notably at different local levels.
Background
The present study aimed to investigate the patients’ perception of the dental practice during the COVID-19 outbreak, and whether the pandemic will affect the attendance of orthodontic ...patients at the dental practice. An online questionnaire, including the Patient Health Questionnaire-4 (PHQ-4), was submitted to Italian dental patients with items about their perceived risks when going to the dentist, concerns about continuing orthodontic treatment, and the onset of temporomandibular disorders (TMD). Data were analyzed with a chi-square test and logistic regression analysis. The level of significance was set at
P
< 0.05.
Results
A total of 1566 subjects completed the survey, including 486 who were under orthodontic treatment or who had a child in orthodontic treatment. A total of 866 participants (55.3%) thought the risk of contracting the COVID-19 infection was higher in a dental practice; this perception was associated with gender (women more than man), age (over 60 years old) and high levels of distress (
P
<0.001). However, 894 patients (57.1%) felt comfortable going back to the dentist. Most of the orthodontic patients (84%) would continue their treatment. After the lockdown, there was a slight increase in the frequency of TMD pain (356 versus 334).
Conclusions
Most of the participants believed that the dental practice is a place at greater risk of contracting COVID-19, even if they continue to go to the dentist. Gender, age, and the level of distress were associated with the increase in the fear of going to the dentist due to COVID-19. Because of the pandemic, 16% of patients undergoing orthodontic treatment would not return to the dental practice to continue their orthodontic treatment after the lockdown. The prevalence of TMD pain in the population increased due to the pandemic.
Objectives
To evaluate the oral health‐related quality of life (OHRQoL) of patients with burning mouth syndrome (BMS) by comparing the Oral Health Impact Profile‐14 (OHIP‐14) and Geriatric Oral ...Health Assessment Index (GOHAI) tests, assessing their dependence with pain, anxiety and depression and, secondly, to analyse the changes in time after treatment with psychotropic drugs.
Methods
Twenty‐six patients and 26 controls were included. The GOHAI, OHIP‐14, visual analogue scale (VAS) and the Hamilton Rating Scales for Depression and Anxiety (HAM‐D and HAM‐A) were performed at baseline (time 0) and after 6 months of treatment (time 1). Descriptive statistics, the Mann‐Whitney non‐parametric test for two independent samples and the Wilcoxon non‐parametric test for two paired samples were used.
Results
The scores from all outcome measurements were statistically significantly different between the cases and controls (P < .001) with a strong correlation between the GOHAI and the OHIP‐14 (P < .001). The BMS patients showed a statistically significant improvement in the VAS, HAM‐D and HAM‐A scores from time 0 to time 1 (P < 0.001), and in the OHIP‐14 scores (P < .004**) after the treatment, but no statistically significant difference in the GOHAI score (.464).
Conclusions
Burning mouth syndrome patients showed poorer scores on all scales compared to the healthy subjects with a lower OHRQoL. OHIP‐14 gives a greater weight to psychological and behavioural outcomes in evaluating oral health than GOHAI, and therefore, it is a more effective questionnaire in terms of the evaluation of the treatment response. The management of BMS can improve pain, anxiety and depression and the OHRQoL.
Prosthetic precision can be affected by several variables, such as restorative materials, manufacturing procedures, framework design, cementation techniques and aging. Marginal adaptation is critical ...for long-term longevity and clinical success of dental restorations. Marginal misfit may lead to cement exposure to oral fluids, resulting in microleakage and cement dissolution. As a consequence, marginal discrepancies enhance percolation of bacteria, food and oral debris, potentially causing secondary caries, endodontic inflammation and periodontal disease.
The aim of the present
study was to evaluate the marginal and internal adaptation of zirconia and lithium disilicate single crowns, produced with different manufacturing procedures.
Forty-five intact human maxillary premolars were prepared for single crowns by means of standardized preparations. All-ceramic crowns were fabricated with either CAD-CAM or heat-pressing procedures (CAD-CAM zirconia, CAD-CAM lithium disilicate, heat-pressed lithium disilicate) and cemented onto the teeth with a universal resin cement. Non-destructive micro-CT scanning was used to achieve the marginal and internal gaps in the coronal and sagittal planes; then, precision of fit measurements were calculated in a dedicated software and the results were statistically analyzed.
The heat-pressed lithium disilicate crowns were significantly less accurate at the prosthetic margins (p<0.05) while they performed better at the occlusal surface (
<0.05). No significant differences were noticed between CAD-CAM zirconia and lithium disilicate crowns (
>0.05); nevertheless CAD-CAM zirconia copings presented the best marginal fit among the experimental groups. As to the thickness of the cement layer, reduced amounts of luting agent were noticed at the finishing line, whereas a thicker layer was reported at the occlusal level.
Within the limitations of the present
investigation, the following conclusions can be drawn: the recorded marginal gaps were within the clinical acceptability irrespective of both the restorative material and the manufacturing procedures; the CAD-CAM processing techniques for both zirconia and lithium disilicate produced more consistent marginal gaps than the heat-pressing procedures; the tested universal resin cement can be safely used with both restorative materials.
The present systematic review aimed to assess the prevalence of oral HPV-related lesions, categorized as benign (verruca vulgaris "VV", squamous cell papilloma "SP", condyloma acuminata "CA", and ...focal epithelial hyperplasia "FEH") and malignant (oral squamous cell carcinoma "OSCC"), in descending order of occurrence in pediatric subjects (≤18 years of age). The secondary objectives were to evaluate the frequency and types of oral lesions described in relation to HPV genotypes and the HPV vaccine type (if any). The study protocol, compliant with the PRISMA statement, was registered at PROSPERO (CRD42022352268). Data from 60 studies, of which quality was assessed using the ROBINS-I tool, were independently extracted and synthesized. Along with seven poorly described benign HPV-related oral lesions that could not be categorized, a total of 146 HPV-related oral lesions, namely 47.26% (
= 69) VV, SP, and CA, 51.37% (
= 75) FEH, and 1.37% (
= 2) OSSC, were diagnosed in 153 pediatric subjects (M:F ratio = 1:1.4) with a mean age of lesion onset of 8.46 years. The viral genotypes detected were HPV-13 (30.61%), -6 (20.41%), -11 (16.33%), HPV-2 (12.24%), -32 (10.20%), -57 (6.12%), and -16 (4.08%). No HPV vaccination was reported in any case. Further studies should be conducted to evaluate the prevalence of HPV-related benign and malignant lesions and the potential role of HPV and associated vaccination in oral carcinogenesis in pediatric subjects.
This review summarizes recent investigations on dental manifestations in celiac disease. Particular attention is paid to delayed dental eruption and maturity, dental enamel defects, molar incisor ...hypomineralization, dental caries, dental plaque, and periodontitis. Most studies confirmed a higher frequency of delayed dental eruption and maturation in children and dental enamel defects in children and adults with celiac disease compared to healthy individuals. The malabsorption of various micronutrients, especially calcium and vitamin D, as well as immunity, is considered the main cause of these conditions. An early diagnosis of celiac disease and introducing a gluten-free diet might prevent the development of these conditions. Otherwise, the damage has already been established, and it is irreversible. Dentists can play an important role in identifying people who may have unrecognized celiac disease and may help prevent its progress and long-term complications. Investigations on dental caries, plaque, and periodontitis in celiac disease are rare and inconsistent; these complaints need further examination.
This study investigated the effect of ultrasonic activation of intracanal‐heated sodium hypochlorite (NaOCl) on its dentinal tubular penetration and root canal cleanliness in vitro. In experiment 1, ...mandibular premolars were randomly allocated to three groups (n = 8): group A, ultrasonic activation; group B, ultrasonic activation of intracanal‐heated NaOCl and group C, syringe‐and‐needle irrigation. Penetration of the fluorescent‐labelled NaOCl was investigated using light microscopy. In experiment 2, mandibular premolars were randomly allocated to group B or C (n = 10), for histological analysis of the remaining pulp tissue and debris. Data were statistically analysed using Kruskal–Wallis and Mann–Whitney tests (P = 0.05). The highest penetration of NaOCl was observed in group B, followed by group A (P < 0.05). Group B showed significantly less amount of debris than group C (P < 0.05). Dentinal tubule penetration of NaOCl and root canal cleanliness were significantly improved by ultrasonic activation of intracanal‐heated NaOCl.
The present umbrella review aimed to characterize the type and regimen of antibiotics administered locally and/or systemically, alone or in combination with surgical and nonsurgical treatments, for ...peri-implantitis and to evaluate and compare the associated clinical, radiographic, and crevicular peri-implant outcomes. The secondary objective was to determine the most effective antibiotic type, route of administration, regimen, and protocols (antibiotics alone or in combination with other approaches) for treating peri-implantitis. The study protocol, which was developed in advance under the PRISMA statement, was registered at PROSPERO (CRD42022373957). BioMed Central, Scopus, MEDLINE/PubMed, the Cochrane Library databases, and the PROSPERO registry were searched for systematic reviews through 15 November 2022. Of the 708 records found, seven reviews were included; three were judged of a critically low and four of low quality through the AMSTAR 2 tool. Locally administered antibiotics alone or as an adjunct to surgical or nonsurgical treatments for peri-implantitis showed favorable outcomes, albeit with limited evidence. The administration of systemically-delivered antibiotics in combination with nonsurgical or surgical treatments remained questionable. Local plus systemic antibiotics have not been shown to have durable efficacy. Due to the heterogeneity of reported antibiotic types, routes, regimens, and protocols, no definitive conclusions could be drawn regarding the most effective antibiotic use in treating peri-implantitis.
The present umbrella review aimed to assess the prevalence of cases diagnosed with lesions potentially due to Titanium (alloy) and other metal nanoparticles released from dental implants and ...implant-supported restorations, characterizing lesions’ macroscopic, imaging, and microscopic features. Secondary aims were to categorize the reported lesions as resembling or ascribable to peri-implant mucositis and peri-implantitis, reactive lesions of the peri-implant mucosa, or hypersensitivity reactions, and to evaluate their relationship with cases’, dental implants, and implant-supported restorations’ characteristics, and with the evidence of Titanium allergy. The study protocol, developed in advance and compliant with the PRISMA statement, was registered on PROSPERO (CRD42022354676). Systematic reviews were searched through the Web of Science, Scopus, MEDLINE/PubMed, Cochrane library databases, and the PROSPERO register until 19 August 2022; reference lists were also screened. Data from four systematic reviews of critically low/low quality (AMSTAR 2), one including a meta-analysis, were analyzed qualitatively. An overall prevalence of 16.9% of cases was estimated. Reported lesions resembled or were ascribable to peri-implant mucositis and peri-implantitis (55.17%), reactive lesions (17.22%), and hypersensitivity reactions (24.12%); no oral contact lichenoid lesions were described. Titanium allergy was hardly and heterogeneously investigated. Due to the severely incomplete data, no definitive conclusions could be drawn on the potential role of cases’ and implant characteristics and Titanium allergy on lesions onset, development, and treatment responsiveness.
Patients hospitalized with COVID-19 pneumonia are at risk for thrombotic complications. At the same time, they need respiratory support, and they frequently require nursing in a prone position. From ...March to May 2020, 57 patients with acute respiratory distress syndrome were admitted to our departments. Our therapeutic protocol included anticoagulant treatment and prone positioning. We have treated three obese women affected by severe pneumonia and pectoral hematoma with post-hemorrhagic anemia. We have already described two of these cases in our previous publication; in this new article, we describe a third similar case and review clinical reports from 2020 to 2022 about hemorrhagic complications during COVID-19. Reports confirm that pectoral hematomas and bleeding in unusual sites are a complication of COVID-19. Pectoral hematomas are likely to be related to COVID-19 severity, heparin dosage, and traumatism due to cough and pronosupination.
