The COVID-19 pandemic literally stopped most human movement and activities as it initially spread, which included dental practices education. This defined the need for significative changes in teaching learning with use of “e-learning” methods, also traineeships. study was designed to determine undergraduate student perception these new methods part their involved 353 students attending Dental School G. D’Annunzio University Chieti–Pescara, from first sixth years. A questionnaire Italian...

Enterococcus faecalis is a microorganism that can be found in the oral cavity, especially secondary endodontic infections, with prevalence ranging from 24–70%. The increase ability to form biofilms presence of subinhibitory antibiotic concentrations phenomenon observed for wide variety bacterial pathogens and associated increased resistance. In this study, therefore, six E. isolates an environment two control strains were exposed Penicillin G, Amoxicillin, Doxycycline, Fosfomycin,...

The study of the maxillary sinus anatomy should consider presence two features clinical importance. arterial supply course and so-called Underwood septa are important factors to when planning surgical treatment reduce risk complications such as excessive bleeding Schneiderian membrane perforations. This aimed investigate above-mentioned anatomical structures improve management eventual vascular in this area. included a total 200 cone-beam computed topographies (CBCTs) divided into groups 100...

Along with the emerging needs of dental patients, numerous techniques for oral tissue stimulation and regeneration were developed to be employed in modern implant rehabilitation therapies.The Concentrated Growth Factors (CGF) are a relatively new therapeutic presidium that can used this purpose, enhancing regenerative potential property blood cells.Although literature presents studies evaluating CGF their clinical uses efficacy, data regarding biological characteristics very few.The present...

The disciplines of biosciences included in the curricula a nursing degree represent daunting but crucial type knowledge that well-prepared nurse should acquire. Given importance and objective difficulties these courses, students experience anxiety, especially for anatomy course. This anxiety related rate exam failures lead professors to analyze their teaching approach, by diversifying lecturing methods. aim our study was test use virtual dissection table (DT) during lectures course,...

The aim of this study was to evaluate the reliability 6-mm-long implants compared with normal-length placed in a vertical augmented atrophic posterior mandible, supporting cemented single crowns. Thirty-six patients bilateral edentulous mandible and presenting bone availability height less than 9 mm from mandibular canal were enrolled study. Patient hemiarches randomized receive both (10 mm). technique used for augmentation "sandwich" technique, using substitute block as graft. data outcomes...

Abstract Background Oral malodor is a very discomforting condition deriving from the presence of volatile sulfur compounds in expired air. In halitosis intraoral etiology, are metabolic products oral microorganisms within biofilm coating tongue dorsum as well other tissues cavity. The aim this study was to characterize and compare microbial composition volunteers suffering healthy by means both culture method culture‐independent cloning technique. Results A high bacterial variety (more than...

The field of regeneration interventions in oral and maxillofacial surgeries still represents a challenge for researchers clinicians. Understanding the biological morphological behaviour human cells towards materials used is key to successfully choosing applying appropriate biomaterials specific clinical situations. aim study was evaluation autologous platelet concentrate obtained with different protocols, culture periodontal ligament fibroblasts (HPLF). design included...

Several types of deproteinised bovine bone mineral (DBBM) are available on the market, and each one is obtained with a thermic chemical process that can differ, achieving different results. Currently, several protocols using low temperature suggested to reduce possible particle crystallisation during production process. This study aimed evaluate biomorphological reaction periodontal fibroblast cultures in contact DBBM particles treated low-temperature protocol (Thermagen®) without exposure...

Over the past decade regenerative branches of dentistry have taken on more and importance, resulting in development performing scaffold materials. These should induce cell adhesion, support, guide tissues’ growth. Among developed materials, we can include resorbable or non-membranes. The purpose this study was to investigate proliferation abilities attachment human periodontal ligament fibroblasts (HPLIFs) over two bovine pericardium membranes with different thicknesses, 0.2 mm 0.4 mm,...

Background. This article aims to report the case of a seven-year-old girl affected by numerical dental anomaly. Supernumerary teeth can lead secondary eruption disturbance crowding and bone cysts formation. Even though clinical instrumental documentation was adequate make correct diagnosis surgicalorthodontic treatment plan, technical error during surgical phase extraction permanent bud instead supernumerary tooth. The presented highlights 2-year follow-up immediate reimplantation avulsed...

Background: Cocaine is a recreational drug known for its negative impact on health and social economic life. One of the complications cocaine abusers cocaine-induced midline destructive lesion (CIMDL) syndrome, which includes extensive destruction osteocartilaginous structures nose, sinus, palate. Methods: Here, we describe three cases surgical management CIMDL using temporalis muscle flap combined with Le Fort I osteotomy, allows sufficient space to settle. Results: The addition osteotomy...

Background: Peri-implantitis, the most prevalent cause of implant failure, is a multifaceted issue that influenced by various factors promote biofilm formation around implant. Although innovative methods for microbiological decontamination dental implants exist, universally accepted standard protocol has not yet been established. However, potential device generates an electric current (Ximplant®) in reducing survival microorganisms within promising development. Methods: In this vitro study,...

The attainment of a good primary stability is necessary condition to ensure the success osseointegration in implantology. In type IV cancellous bone, however, it possible that reduced can lead an increased rate failure. aim this study was therefore determine, with help resonance frequency (Osstell mentor), which technique implant site preparation (piezo surgery, conventional, under-preparation, bone compaction, osteodistraction) and macro-geometry able improve bone.10 pig ribs were prepared...

Purpose The aim of the present in vitro study was to evaluate leakage observed for 2 different microbial species at level implant–abutment (I-A) interface, and marginal fit size microgap I-A interface implant connections. Methods Ten specimens each group were tested. inner parts 5 implants per inoculated with 0.1 μL a viable Enterococcus faecalis suspension Aggregatibacter actinomycetemcomitans. All vials containing control incubated 37°C under aerobic condition E. presence 5% CO A. They...

Mancozeb, an ethylene bis-dithiocarbamate, is widely used as a fungicide and exerts reproductive toxicity in vivo vitro mouse oocytes by altering spindle morphology impairing the ability to fertilize. Mancozeb also induces premalignant status granulosa cells (GCs) cultured vitro, indicated decreased p53 expression tenuous oxidative stress. However, presence extent of ultrastructural alterations induced mancozeb on GCs have not yet been reported. Using model toxicity, comprising parietal from...
