Many different osteotomy procedures has been proposed in the literature for dental implant site preparation. The osseodensification is a drilling technique that has been proposed to improve the local ...bone quality and implant stability in poor density alveolar ridges. This technique determines an expansion of the implant site by increasing the density of the adjacent bone. The aim of the present investigation was to evaluate the effectiveness of the osseodensification technique for implant site preparation through a literature review and meta-analysis. The database electronic research was performed on PubMed (Medline) database for the screening of the scientific papers. A total of 16 articles have been identified suitable for the review and qualitative analysis-11 clinical studies (eight on animals, three on human subjects), four literature reviews, and one case report. The meta-analysis was performed to compare the bone-to-implant contact % (BIC), bone area fraction occupied % (BAFO), and insertion torque of clockwise and counter-clockwise osseodensification procedure in animal studies. The included articles reported a significant increase in the insertion torque of the implants positioned through the osseodensification protocol compared to the conventional drilling technique. Advantages of this new technique are important above all when the patient has a strong missing and/or low quantity of bone tissue. The data collected until the drafting of this paper detect an improvement when the osseodensification has been adopted if compared to the conventional technique. A significant difference in BIC and insertion torque between the clockwise and counter-clockwise osseodensification procedure was reported, with no difference in BAFO measurements between the two approaches. The effectiveness of the present study demonstrated that the osseodensification drilling protocol is a useful technique to obtain increased implant insertion torque and bone to implant contact (BIC) in vivo. Further randomized clinical studies are required to confirm these pieces of evidence in human studies.
Rising antibiotic use is a serious threat to the success of therapy in dentistry for bacterial resistance and side effects to the patients. The dentist community in Albania prescribing too many ...antibiotics. This survey assesses the mode of antibiotic use among Albanian dentists, with appropriate dosage and regimen, and antibiotic stewardship and their knowledge of relevant guidelines. Material and Methods: This survey study was conducted among 180 Albanian dentists. The questionnaire was distributed through e-mail addresses found in the database of the Faculty of Dental Medicine, University of Medicine of Tirana. We assessed 180 dentists out of which 154 (85.56%) completed the entire questionnaire. Results: There were 24,870 prescriptions in adult patients from 154 dentists for a period of six months with an average of 1,243 prescriptions per week. The most used antibiotics were fixed combinations of amoxicillin-clavulanic acid (67.43%) and azithromycin (39.3%) for allergic patients to beta-lactams. The results for antibiotic stewardship were incorrect in 37.01% of total providers, and gastrointestinal disorders were reported as side effects. Conclusion: This survey conducted among Albanian dentists shows a different trend of using antibiotics than in other countries. To tackle the current antibiotic resistance, dentists must be an important part of the antimicrobial stewardship program of the Public Health Institution in Albania to change individual behavior.
Adhesive restorations have been shown to guarantee excellent performance and longevity, although this comes with some disadvantages. Among these, the vulnerability of dentine to different agents has ...been widely evaluated. The aim of this study was to evaluate the possible penetration of impression materials into freshly cut dentine. Dentine from 27 teeth was impressed with polyether (Impregum Penta L) (nine teeth) and with polyvinyl siloxane (Aquasil Ultra LV) (nine teeth). The surface of nine teeth after the impressions were used as the control. Specifically, the extroflections caused by the imprinting of the dentinal tubules on the impression material, the so-called impression tags, were measured. Furthermore, the presence of the material inside the tubules was examined. Scanning electron microscopy analysis showed material tags for all of the experimental groups. The mean lengths (±SD) were 22.6 (±11.0) µm for polyether, 21.8 (±12.8) µm for polyvinyl siloxane and 11.3 (±7.0) µm for the tooth control, with mean diameters (±SD) of 2.8 (±0.5), 2.4 (±0.7) and 3.1 (±0.7) µm, respectively. Fractal analysis showed fractal dimensions of 1.78 (±0.03), 1.77 (±0.03) and 1.71 (±0.03), respectively. These data demonstrated that the impression materials can remain inside the dentinal tubules, which can adversely affect the adhesive procedures.
In the context of the SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) pandemic, the medical system has been subjected to many changes. Face-to-face treatments have been suspended for a ...period of time. After the lockdown, dentists have to be aware of the modalities to protect themselves and their patients in order not to get infected. Dental practitioners are potentially exposed to a high degree of contamination with SARS-CoV-2 while performing dental procedures that produce aerosols. It should also be noted that the airways, namely the oral cavity and nostrils, are the access pathways for SARS-CoV-2. In order to protect themselves and their patients, they have to use full personal protective equipment. Relevant data regarding this pandemic are under evaluation and are still under test. In this article, we made a synthesis about the way in which SARS-CoV-2 spreads, how to diagnose a novel corona virus infection, what the possible treatments are, and which protective personal equipment we can use to stop its spreading.
In oral implantology, the success and persistence of dental implants over time are guaranteed by the bone formation around the implant fixture and by the integrity of the peri-implant mucosa seal, ...which adheres to the abutment and becomes a barrier that hinders bacterial penetration and colonization close to the outer parts of the implant. Research is constantly engaged in looking for substances to coat the titanium surface that guarantees the formation and persistence of the peri-implant bone, as well as the integrity of the mucous perimeter surrounding the implant crown. The present study aimed to evaluate in vitro the effects of a titanium surface coated with polylysine homopolymers on the cell growth of dental pulp stem cells and keratinocytes to establish the potential clinical application. The results reported an increase in cell growth for both cellular types cultured with polylysine-coated titanium compared to cultures without titanium and those without coating. These preliminary data suggest the usefulness of polylysine coating not only for enhancing osteoinduction but also to speed the post-surgery mucosal healings, guarantee appropriate peri-implant epithelial seals, and protect the fixture against bacterial penetration, which is responsible for compromising the implant survival.
The SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is a high-risk viral agent involved in the recent pandemic stated worldwide by the World Health Organization. The infection is ...correlated to a severe systemic and respiratory disease in many cases, which is clinically treated with a multi-drug pharmacological approach. The purpose of this investigation was to evaluate through a literature overview the effect of adjuvant therapies and supplements for the SARS-CoV-2 infection. The research has analyzed the advantage of the EK1C4, by also assessing the studies on the resveratrol, vitamin D, and melatonin as adjuvant supplements for long hauler patients' prognosis. The evaluated substances reported important benefits for the improvement of the immune system and as a potential inhibitor molecules against SARS-CoV-2, highlighting the use of sartans as therapy. The adjuvant supplements seem to create an advantage for the healing of the long hauler patients affected by chronic symptoms of constant chest and heart pain, intestinal disorders, headache, difficulty concentrating, memory loss, and tachycardia.
(1) Background: The overdenture is a complete denture, an implant-supported prosthesis, that the patient can remove at home for the usual oral hygiene procedures, thanks to a simple and intuitive ...anchoring system. Clinically, the execution of this rehabilitation for the lower arch is often favored, but when it is necessary to limit the extension of the palate in the upper arch, it can represent the least invasive and economic solution. The aim of the study is to analyze post-loading implant loss for implant-supported prostheses in the edentulous upper jaw. (2) Methods: This retrospective study was carried out on patients who received a superior overdenture on four implants for rehabilitation. A total of 42 patients were included in this study and initially evaluated clinically and radiographically. The follow-up period for patients after delivery of the upper overdenture is between 48 and 72 months. A total of 168 implants were inserted and monitored in this period. Clinical and radiographic tests were carried out on all 168 implants, with constant re-evaluation. (3) Results: The overall implant survival rate is 92.9%, a value that corresponds to those present in the literature in previously published studies. There were few prosthetic complications, mainly the detachment of anterior prosthetic teeth. (4) Conclusions: Most of these complete prostheses, which as antagonist had another previously made overdenture on four or on two implants, achieved excellent success rates in this study at 72 months.

Gender-specific medicine studies how sexual biology and gender-related cultural and behavioral differences may influence a person’s health and considers the differences in clinical features, ...prevention, therapies, prognosis, and psycho-social aspects of diseases with different impacts on women and men. The present work summarizes the main differential impact each risk factor for oral cancer and periodontitis has according to biological sex- and gender-oriented differences. It resulted in differences in epidemiology and the weight of various healthy determinants that may influence the incidence and prognosis of oral cancer and periodontitis. It is desirable to change the methodology of scientific studies with a higher focus on the weight that sexual variables may have on the well-being or the probability of getting ill of each person, thus promoting the development and diffusion of personalized gender dentistry.
To investigate the therapeutic and prophylactic use of antibiotics in dentistry in two countries.
This study used questionnaires to examine the prescribing habits of dentists in Italy (9th country in ...Europe for systemic antibiotic administration) and Albania an Extra European Union Country. A total of 1300 questionnaires were sent to Italian and Albanian dentists.
In total, 180 Italian and 180 Albanian dentists completed the questionnaire. Penicillin use was higher in Italy (96.6 %) than Albania (82.8 %). Only 26.1 % of Italian dentists and 32 % of Albanian dentists followed the national guidelines for antibiotic administration.
Dentists tend to overprescribe antibiotics for treating existing conditions or as prophylaxis. They also highlighted a lack of adherence to established guidelines for antibiotic use. In addition, factors such as age, nationality, and sex appeared to influence the choice of antibiotics.
Recently, the growth of antibiotic-resistant bacteria has become a global concern. The authors of this article highlight how dentists often prescribe antibiotics without a real need. Limiting the use of antibiotics in this category may help mitigate antibiotic resistance.
