RESUMEN
The occlusal trauma has been defined as an injury to the periodontium resulting from occlusal forces that exceeds the reparative capacity of the attachment apparatus. Currently, the effects of occlusal trauma on tooth support tissues, the onset and the progression of periodontal disease are still debated. In fact, researchers started evaluating the possible effects of occlusal discrepancies on incidence, progression, and treatment outcomes of periodontitis, but all the results underlined the more significant role played by microbiological flora. The results of this study show that after 60 days of treating the occlusal trauma, a significant reduction was achieved in the periodontal bacterial flora.

White spot lesions (WSL) are demineralizations of the enamel found on the tooth surfaces. WSL are considered incipient non-cavitated caries caused by bacterial plaque activity. Subjects with malocclusion such as dental crowding and fixed orthodontic appliances have a greater number of retention sites and consequently difficulty in cleaning and greater predisposition to caries. In fact, WSL are a frequent side effect of orthodontic fixed treatments. The prevention and resolution of this problem is the goal of any orthodontist because untreated WSL can lead to the formation of deeper dental caries and restorative treatment with consequent compromise of patient satisfaction with the aesthetic result obtained at the end of the orthodontic treatment. This review is intended not only for orthodontists but also for general and pediatric dentists who want to learn how to correctly prevent, and treat this unsightly problem. On the market there are many products sold to achieve this goal, some of them can be managed independently by the patient at home, others require the intervention of the dentist. The purpose of this literature review is to understand how these substances work, to identify with which of the currently most widespread the best results have been obtained and then to provide useful information to guide the clinician in choosing the most suitable one for the patient.

The research is aiming to obtain at room temperature a new ceramic material containing partially stabilized zirconia with different oxides after sintering used for dental and other technological purposes. Our research proposes a new method based on the use of stabilized zirconia with other oxides to obtain optimized dental material with a lower cost price and / or improved properties to allow wider use of these products to an increased number of patients in dental offices. X-ray diffraction, SEM analysis. FTIR spectroscopy, UVVis and density measurements were accomplished for the three ceramic systems. The correlation between the microstructure and the spectroscopic properties of zirconium stabilized by FTIR spectroscopy, UV-Vis helps understanding the mechanisms associated with the formation of high (tetragonal and / or cubic) temperature zirconia. Along with the simple, less costly preparation method and high purity of the ceramic products our study offers a highly desirable product for technological applications.

The diabetes and osteoporotic metabolic diseases are characterized by a wide prevalence of the population worldwide and correlated to alteration of the bone tissues. Several cofactors could influence the clinical course and the biochemistry of the pathologies such as human microbiome, nutrition characteristics, gut microbiota activity and interactions with vitamin K and D across IGF/GH and TP53 signaling pathways and the glucose/energy as mechanism for bone tissue health. Moreover, also the calories and sugar consumption seem to be correlated to an increased inflammatory state with several consequences for hematopoiesis and host tissues response. The aim of the present literature review was to highlight the role of osteoporotic diseases and diabetes type 2 link for the bone metabolism. The literature cases showed that a correlation between bone-gut-kidney-heart-CNS-Immunity crosstalk seems to be linked with bone metabolism and health regulation. Moreover, also the aging process could represent a valuable co-factor for the sustaining of the metabolic disorders upon a multi-systemic level.

Anterior open bite is one of the most complex malocclusions to manage. The interaction of skeletal, dental, and soft tissue effects can contribute to develop an anterior open bite. The skeletal open bite requires a more complex approach of treatment to reach function, aesthetics, and stability. The approaches vary depending on the causative factors and the age of patients. Treatment approaches for open bite patients differ when dealing with adults and growing patients. The aim of this descriptive review was to summarize the main existing treatment strategies for anterior open bite, from the noninvasive behavioural shaping to the orthodontic intrusion with skeletal anchorage.

Resorption of alveolar ridge after tooth extraction often compromises dental implant placement and esthetic. Alveolar ridge preservation is a common procedure performed in order to preserve the pontic site for a prosthetically ideal position. This procedure has already become an indisputable need. Tooth matrix as bone substituted material poses osteoconduction and osteoinduction properties and as autologous graft, this material is free of antigenic reaction. This biomaterial allows the threedimensional reconstruction of the bone, is easy to prepare and has a low cost. The aim of this review is to summarize and put in evidence the properties of tooth as bone substitute and its use in alveolar ridge preservation. Keyword: autologous tooth, autologous graft, bone regeneration, bone substitute, alveolar ridge preservation, alveolar ridge augmentation, socket preservation.

Treatments with removable appliances are widely used in Europe to correct dento-skeletal dysgnatia in the growth phase that is a period of poor cooperation of the patients. Adherence to the wear-time prescription is often not achieved and it represent the main argument against the use of removable devices. Suspected non-compliant behavior with the wear time prescription is often the subject of medico-legal disputes, which can deteriorate doctor-patient relationship. The use of microchips allows to document objectively and clarify the patient's behavior. To conduct a systematic review of the orthodontic literature to identify the factors associated with compliance in orthodontic treatment. We conduct a systematic review that aimed to identity the factors associate with compliance in orthodontic treatment. The main purpose was to assess the objective levels of time of use of the removable appliances and the self-reported levels. A literature search was conducted by the electronic databases PubMed and Cochrane Library. The following search terms were used: compliance functional removable orthodontic appliance. Randomized and nonrandomized controlled trials, prospective cohort studies, case series, qualitative and mixed-methods studies objectively assessing compliance levels were included in the study. A total of 94 articles were identified by PubMed and 14 articles by Cochrane. The papers selected were included for the qualitative analysis and categorized according to the subjects age, the clinical appliance, compliance factors, wear time and monitoring. Removable appliances are an important part of orthodontic treatment, used in growth phase of the patient. Collaboration with removable functional devices determines success / failure in treatment.

Skin cancer basal cell carcinoma (BCC) is a quite common lesion with a worldwide annual incidence between 3% and 8%. Tissue reconstruction should be biologically driven: nowadays, the naso-genial flap is one of the safest and usable flaps for the reconstruction of the labial and nasal region after invasive surgery aimed at a full BCC excision. In fact, the proximity of this flap to the area to be treated, the similar colour of the skin and the technical possibility to perform a single surgery to both harvest the flap and remove the lesion in the area to be then reconstructed, make it highly preferred by surgeons. In order to prevent the most severe swelling, the Authors started to use a novel method consisting in the use of the small-diameter cannula for lipoaspiration technique (SDCL). The correct use of SDCL allows to aspirate the adipose tissue, thus obtaining an available adipose-based scaffold, highly compatible with the area in which the flap is to be placed.

Osseo-degeneration is a disorder related to several factors, that may lead to the disruption of several skeletal regions providing support, such as the femur head, the vertebrae and the alveolar bone. The functional condition can be restored by means of grafting procedures, using different materials: calcium powder, xenografts, ceramics and metals. Such procedures aim at reforming an adequate bone volume and strength, that is necessary to support loading forces. Bone regeneration requires that the basic biological principles of osteogenesis, osteoinduction, osteoconduction and biocompatibility are followed. The success of regenerative procedures may depend on the inner structural, mechanical and metabolic condition of the host's bone on which implants should be inserted, on the surgical technique, and on the biomaterial used. Among these, the aging process of the patient appears to be relevant. It can be associated with metabolic disease leading to systemic functional decay, which involves a gradual steady decline of hormonal, immune function and osteo-metabolic activity. The latter can affect the positive outcomes of bone reconstruction and implant therapy. This review will analyze the biological and physiological factors involved in the bone tissue break-down, such as the influences from gut microbiome unbalance and the consequent metabolic, endocrine, immune dysfunctions, the surgery procedures and the quality of the grafting material used. The decline of bone architecture and strength should be corrected by using an appropriate clinical regenerative approach, based on a bio-endocrine, metabolic and immunologic know-how. The final characteristics of the regenerated bone must be able to support the loading forces transmitted by the implants, independent of the body location, and should be individualized according to the different condition of each patient.

Our group recently developed an innovative maxillary sinus augmentation technique without the need of sinus membrane elevation, termed as "IPG" DET protocol. This technique utilizes autologous platelet concentrates (including platelet rich plasma (PRP), platelet rich fibrin (PRF), growth factors (GFs) and CD34+ stem cells), together with bone grafting materials positioned through intentionally perforated Schneider's membrane for flapless implant placement. This study aimed at evaluating the performance of "IPG" DET protocol in terms of new bone formation and implant stability at 8 months post-op. This prospective study consisted of forty-eight patients with a mean age of 52.8 years. A total of eighty-five implants were placed with "IPG" DET protocol in combination with autologous platelet concentrates. CBCT (cone beam computed tomography) was performed at two different time points: pre-operatively and at 8 months post-op. CBCT images were then compared by an intensity-based image algorithm to assess the newly formed bone in terms of gray scale values. Additionally, implant stability quotient (ISQ) was used to estimate implant osseointegration and success rate. The average new bone formation was 5.9 ± 0.9 mm2 per implant. All implants successfully osseointegrated, and ISQ ranged 62.3-71.7. According to the results of this study, "IPG" DET protocol in combination with autologous platelet concentrates is a successful technique for implant-supported rehabilitation of the edentulous posterior maxilla without the need of sinus floor elevation.

OBJECTIVE: Nutrition plays a significant role in preserving the balance of the human body. Considering each person's particular characteristics, diet can directly and indirectly alter the body's immune response. The purpose of this study is to draw attention to the connection between a vegetarian diet and its impact on oral health. MATERIALS AND METHODS: To determine the connection between a vegetarian diet and dental health, a search of the literature was conducted on the PubMed, Scopus, and Web of Science databases. English language and a publication year between January 1, 2013, and March 1, 2023, were the inclusion criteria for the search. RESULTS: There were 167 articles in total that addressed the subject of interest, and 18 of them were chosen for qualitative analysis. CONCLUSIONS: This study suggests that a vegetarian diet may alter oral health, namely periodontal health, tooth erosion, and oral microbiome. Even if the data collected prevents the effect of a vegetarian diet on oral health from being confirmed, this study acts as a starting point for future, more focused research.

OBJECTIVE: A biomaterial is any non-pharmaceutical substance or a mixture of synthetic or natural substances used independently or as part of a system for any amount of time with the aim of mending, supporting the growth, or replacing tissues, organs, or functions of the body. It is a non-renewable material that interacts with biological systems. The purpose of this study was to assess the advances in ceramic biomaterials and perform a bibliometric mapping of the literature on the subject. MATERIALS AND METHODS: The Scopus database was used for manuscript screening (Elsevier, Amsterdam, The Netherlands). The effect of the scientific production has been assessed using scientometric citational metrics. RESULTS: A total of 2,554 pieces of literature, including 2,234 papers, 170 conference proceedings, 109 reviews, 35 book chapters, 3 editorial letters, and 3 short surveys, were retrieved. Based on the research conducted, it is noted that ceramic materials are high-performing by being porous or glassy and can, therefore, serve as fillers, covering materials, and scaffolds in medicine and biotechnology. They are frequently employed not only in orthopedic and maxillofacial surgery but also in dentistry for dental prostheses. CONCLUSIONS: Materials monitoring methods enable us to track the three-dimensional evolution of ceramics' volume, as well as flaws or micro-cracks.

OBJECTIVE: The COVID-19 pandemic had a major impact on our lives all over the world. Changes have occurred in daily life as well as in all medical services. The aim of the present study was to evaluate the emergency accesses in four universities' emergency services during the lockdown period from March to June 2020 during the COVID-19 pandemic. SUBJECTS AND METHODS: A cross-sectional study was carried out on 44,787 patients to evaluate the emergency services of university centers. The medical data of Medical Emergency Service Data (MESD) were assessed by five independent operators considering the epidemiological findings for statistics methods. RESULTS: A lower level of emergency access was reported in March-July compared to the pre-COVID period. The epidemiological data confirmed that female pathologies were more frequent compared to male patients. A fluctuation for almost all urgent healthcare centers was detected, showing one/two peaks per year during the years 2017-2019. The COVID-19 pandemic period did not influence the variety of pathology detected. CONCLUSIONS: After the lockdown period, the emergency services slowly increased in cases. The pre-COVID period showed an overlapping of the most frequent pathologies compared to the post-COVID period: periodontitis (Bari and Tirana), dental fractures (Bari and Bucharest), odontogenic abscess (Bari, Cluj and Tirana).

OBJECTIVE: Molnupiravir (MOV) is an oral antiviral drug that received use authorization in Vietnam for the treatment of mild COVID-19 (F0). There was a need to develop alternative approaches that allowed patients to access medication, decongest hospitals, clinics, and facilities, and protect people from infection. During the COVID-19 crisis, the Ninh Thuan Health Authorities implemented the home delivery of medication by community health workers. This study conducted in collaboration with two important Italian entities [the Aldo Moro University of Bari City and the 118 Department of Territorial Emergency System (118 SET) of Taranto City] aimed to evaluate the implementation of home delivery F0 treatment package assessing the rate of infection recovering during the coronavirus pandemic in Ninh Thuan province, Vietnam. PATIENTS AND METHODS: A convergent mixed methods research, based on a longitudinal study with quantitative research and qualitative assessments, evaluated four implementation outcomes: the feasibility, fidelity, coverage, sustainability, and effectiveness of the initiative. Data sources included routinely collected data, a telephonic survey of patients, an analysis of set-up and recurrent costs, as well as descriptive exploratory qualitative and quantitative analysis. RESULTS: After taking the MOV for 5 days, only 35 out of the initial 400 F0 patients remained positive, while 365 patients (91.2%) were negative (CT≥30). Whilst, the successful rate after using the drug during the course accounted for 99.85% and 100% after the entire treatment course, without any death. After 5 days of taking the drug, a positive test result (CT<30) was associated with age group ≥60 (OR=2.7) and comorbidities (OR=3.0) (p<0.05) compared to negative and positive results (CT≥30). Negative factors impacting F0 at home include a shortage of healthcare workers, inadequate supply of thermometers and SpO2 meters, and insufficient financial support for healthcare workers. CONCLUSIONS: MOV caused a reduction in the risk of hospitalization or death in mild COVID-19 patients, and molnupiravir was also found to be well tolerated and safe without any major adverse events during the administration period.

OBJECTIVE: Since 1967, when the osteoinduction properties of autogenous demineralized dentin matrix were discovered, autologous tooth grafts have been advocated as a viable option to autologous or heterologous bone graft. Tooth graft materials may be extracted from the patient's whole tooth using a granulating device. The aim of this study was to examine the size of granules obtained by the Tooth Transformer (TT)® device, using a laser instrument with high precision. MATERIALS AND METHODS: The TT® device can obtain bone graft material in a short period from an extracted tooth. The resulting material can act as an osteoconductive scaffold, providing a mineral substrate during resorption, including platelet growth factors and morphogenetic proteins. Different studies have investigated the dimension and behavior of various graft material particles, since the size of the grafted particles may play a role in osteogenesis and bone regeneration. RESULTS: Different dimensions of granules are available: small (< 400 µm), medium (400 µm-1,000 µm) and large (1,000 µm-2,000 µm). From 4.03 µm to 100 µm the percentage of granules was 14.52 ± 1.93%. A larger part of the granules was up to 100 µm, while 85.47 ± 1.93% of the granules were from 100 µm to 1,000 µm. CONCLUSIONS: 85% of the granules produced were in accordance with the dimensions suggested in the literature.

Data collection has suggested a complex correlation between the gut microbiota (GM) and bone homeostasis involving host-microbiota crosstalk. Although the GM is known to affect bone metabolism, the mechanisms linked with these effects remain unclear. The aim of this review is to current insight advances regarding how gut-derived hormones regulate bone homeostasis in humans, emphasizing gut-bone axis and bone regeneration. The GM may be engaged in bone metabolism and fracture risk. Additional investigations of the fundamental microbiota-related pathways in bone metabolism may uncover treatment strategies and enable the prevention of osteoporosis. A better knowledge of gut hormones' action on bone homeostasis may lead to new strategies for preventing and treating skeletal frailty related to age.
