RESUMO

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).

RESUMO

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.

RESUMO

AIM: In this study we present the new postoperative oro-myofunctional protocol following frenectomy by atmospheric plasma associated with a systemic postural approach, which determines functional recovery through body symmetry restoration based on the concepts of the French "Mezieres Method" and postural bench. METHODS: A total of 130 patients (76 female, 54 male) affected by ankyloglossia of class III/IV, according to Kotlow's Tongue Tie Classification have been treated with atmospheric plasma followed by oro-myofunctional therapy associated with a systemic postural approach. The overall change, improved/worsened speech, feeding, or sleep has been evaluated through the 10 points Parents Speech Satisfaction (PSS) Score after one week and two months. CONCLUSION: Based on the findings of the current investigation, myofunctional therapy in tongue-tie results in a consistent significant functional ameliorating of feeding capability, speech and sleeping of subject treated as reported with traditional oro-myofunctional therapy.

RESUMO

OBJECTIVE: The purpose of the present clinical study is to assess the effectiveness of a lipolytic solution containing sodium salt of ascorbic acid at 0.24% and a surfactant agent at 0.020% ascorbyl-palmitate (SAP) for the treatment of double chin. PATIENTS AND METHODS: A total of 10 healthy adult subjects affected by double chin (8 female and 2 male) were evaluated in the present investigation. The patients were admitted to a total of 4 sessions, with biweekly procedures, without no other active agents addiction. RESULTS: In all the subjects a reduction of the convexity of the chin after the treatment with SAP was observed. Improvement in submental appearance was achieved in 90% (9/10) of the patients. One patient did not see any improvement in submental appearance after two section treatments and withdrew from the treatment. CONCLUSIONS: In conclusion, in the present study, a new adipocytolytic solution consisting of sodium ascorbate mixed with ascorbyl-palmitate was used with success as a surfactant agent for the treatment of double chin.

RESUMO

OBJECTIVE: New methods for biofilm removal are being investigated. A recent new one involves the use of the electric field for biofilm removal. In particular, electrolytic cleaning works on the adhesion forces of the biofilm on the surfaces, with few studies showing promising results in decontamination and implant re-integration in the bone. This study aims at assessing the effect of a new decontamination device that implies the electric field for implant-biofilm removal. MATERIALS AND METHODS: Three implants affected by peri-implantitis were selected for the study. After the treatment, the implants were observed by the Scanning Electron Microscopy. RESULTS: All three samples showed no microbial biofilm in the application area, while the rest of the surface observed was covered with microbial biofilm, with an intensely thickened bacterial population. CONCLUSIONS: Peri-mucositis and peri-implantitis prevention and early treatments are essential for implant maintenance, thus saving the surrounding hard and soft tissues. The technological innovation is providing electrolytic devices which act not only on the microbial population but on the biofilm adhesion to the implant surface, with promising results for a new and valid therapeutic option.

RESUMO

OBJECTIVE: The aim of the present investigation was to evaluate, by an in vitro simulation, the mechanical behavior of the conical vs. internal hexagon under cyclic load and the microleakage of the prosthetic connection of the fixture. MATERIALS AND METHODS: A standardized cyclic loading was performed considering the implant with conical connection (diameter 4 mm - length 10 mm) (CS) and internal hexagon connection (diameter 4 mm - length 10 mm) (IH). The toluidine blue infiltration has been evaluated with the paper cone test. RESULTS: After a total of 5x104 loads, the screw has been removed and the abutment appears solid and stable to the implant fixture for CS, while the IH was unstable. There was no infiltration of the toluidine marker in the connection interfaces of CS implants, while the IH was positive to the paper cone test. CONCLUSIONS: The study data showed that the conical connection showed higher stability compared to the internal hexagon connection under the loading and it is able to prevent bacterial microleakage. This effectiveness should be considered for the long-term maintenance of the peri-implant soft and hard tissues around the fixture.

RESUMO

OBJECTIVE: The purpose of this study was to investigate possible differences in the filling of the various recesses of the maxillary sinus after the procedure of sinus floor elevation in relation with the initial volume of the same and if the sinus volume can influence long-term graft dimensions, by using cone beam computed tomography (CBCT) as diagnostic analysis device. PATIENTS AND METHODS: This study included 32 sinuses corresponding to 16 patients referred for bilateral maxillary sinus augmentation procedures needing to increase the volume of the surgical site with the porcine cortical bone for dental implant placement in the posterior maxilla. The sinuses were analyzed by preoperative and postoperative (15 days and 6 months after sinus surgery) cone beam computed tomography. RESULTS: No statistically significant relations were observed between initial sinus dimensions and the entity of the contraction of the graft between T1 (15 days after surgery) and T2 (180 days after surgery). The behavior was the same either for the large sinus (> 15.65 cm3) and for the small one (< 15.65 cm3). Instead, about the filling of the various sinus recesses, a linear regression model was used to explain the difference between the mean preoperative and postoperative surgical spaces; in most of the samples, the filling of the anterior recess was ~15% of the total volume of the graft, i.e., the minor one among the main recesses. CONCLUSIONS: Our findings suggest that: (1) in the procedure of sinus floor augmentation by a lateral approach with deproteinized porcine bone there are no relations between the initial dimensions of the sinus and the long-term dimensional changes of the graft, and (2) that, among the main recesses of the sinus, the anterior one is generally the less filled.

RESUMO

BACKGROUND: Horizontal atrophic ridges need a regenerative procedure for implant positioning and fixed rehabilitation. Cone Morse taper implants are characterized by the intimate fitting of the prosthetic interface with the absence of microgaps and micromovements of the interfaces. The aim of this case report was to evaluate the clinical outcome of Cone Morse implant design in split crest augmentation treatment. CASE REPORT: A female patient with partial edentulism of atrophic posterior maxilla was treated for split crest procedure and implant-supported rehabilitation. A full-thickness flap was elevated, and horizontal and vertical osteotomic lines were produced with piezoelectric device. A total of 4 Cone Morse Taper implants (Universal III, Implacil de Bortoli, Brasil) were positioned and the site was grafted with bone substitute and covered by a heterologous membrane. CONCLUSIONS: A complete healing of the surgical site was evident at the follow-up with no evidence of bone resorption. No radiolucency or inflammatory aspects of the treated site were evident in the radiographic control. Simultaneous Cone Morse implants positioning with split crest technique seems to be a promising treatment for posterior maxillary rehabilitation of atrophic edentulous ridges.

RESUMO

Sufficient hemostasis during oral surgical procedures is crucial for successful outcomes and to reduce healthcare resource utilization. The purpose of this narrative review is to give a rational insight into the management of bleeding in oral and dental practice through modern drugs. A narrative literature review has been performed on the present topic identifying all articles on Pubmed/Medline and Google Scholars. Acceptable hemostasis during oral surgery is also required to improve visibility and provide a dry operational area. Many oral surgeons, in their daily practice, encounter problems in controlling postoperative bleeding and use a topical hemostatic agent to promote platelet activation or aggregation to form a stable clot.

RESUMO

BACKGROUND: In parallel with the increase in requests for filler injections, reported complications (immediate or delayed and transient or permanent) increased too. CASE REPORT: In the presented case report, a patient reported a delayed complication of filler injection. The complaints of the patient and the objective evaluation revealed the presence of multiple lip nodules, that were painful both spontaneously and at the touch, after 10 years from a lip filler injection. The surgical excision of the neoformations permitted the complete healing of the lesions. The histological analysis showed a not specific pattern, showing a material encapsulated by a tissue reaction, confirming that the possible cause of the multiple injuries could be attributable to the injection received years earlier. CONCLUSIONS: The professional who intends to perform filler injections needs a complete training process, both from a theoretical and practical point of view. Also, the patients must be informed of the possible risks associated with each product.

RESUMO

OBJECTIVE: In Europe, a great number of investigations and studies followed up to develop safer techniques performed by physicians only. Successful dedicated medical protocols included the implant of single fibers with extractable root. The aim of our study was to evaluate the efficacy of biocompatible artificial hair implants in patients with androgenetic alopecia. PATIENTS AND METHODS: 682 patients (488 males and 184 females) aged between 25 and 70 years old, with diagnosed AGA, requiring no invasive nor surgical hair restoration, with problems of baldness and refusing surgical options appealed to the Second Opinion Medical Consulting (Modena, Italy), and were included in the present protocol. Before the treatment, all patients underwent a test implant to rule out hypersensitivity by implanting 100 fibers on a selected skin spot. If no reaction was detected, five weeks later 500-1,200 fibers were further implanted per session at a minimum interval of 5 weeks until the required aesthetic result was achieved. RESULTS: The average number of sessions for each patient was 5. The average number of implanted fibers was 2,100 (ranging from 800 to 12,000). The treated scalp area returned to normal appearance and tenderness in 3 days. CONCLUSIONS: The socio-phycological benefit and the life quality improvement of our patients have been the focus of the study. On our side, the accurate selection, small hair units for each implant session, customized dermatological consultation and the use of highly biocompatible fibers have been the proper strategy to achieve the goal.

RESUMO

OBJECTIVE: The physical and physical chemistry is able to influence the interaction of the scaffolds and bone substitutes with the body fluid and blood. The aim of the present investigation was to evaluate the wettability properties of an Mg-HA Chitosan-based Gel with blood vs. autologous platelet gel. MATERIALS AND METHODS: A total of 6 study groups were evaluated according to the Mg-HA Chitosan-based Gel thickness (1, 2 and 3 mm) and the fluids (blood vs. autologous platelet gel). The biomaterial wettability was conducted through the sessile drop technique. RESULTS: The study findings showed a significant difference in contact angle between the APL and blood groups (p<0.05). The MG-Ha Chitosan-based membrane thicknesses seem to produce no significant effects on contact angles measurement for all groups (p>0.05). CONCLUSIONS: In the present investigation, a similar MG/Ha gel membranes wettability was reported between APL and blood groups. In addition, a high hydrophilicity of MG/Ha gel membranes was reported with a potential advantage in terms of a more effective osteogenic capability in the clinical practice.

RESUMO

Cellulite is a common topographic condition of the skin manifested as lumpy, dimpled flesh resembling an orange peel on some zones such as the thighs, hips, buttocks and abdomen. The aetiology of this cosmetic issue is multifactorial, with hormonal, anatomical, environmental and genetic factors influencing its origin, although the exact mechanisms which cause this condition are still unknown. In the present work, a bibliographic analysis of the cellulite etiology has been updated and exposed, as well as the multiple classification grade scales established over the decades. In addition, a new method to classify cellulite severity, in which the clinical manifestations are correlated to the histological aspects more frequently found in the patients, has been presented. Several theories regarding its appearance, structure and clinical aspects have arisen with the aim of developing and establishing a valuable therapeutic approach. However, the lack of a consensus regarding the classification of cellulite severity has complicated the developments within this field.

RESUMO

OBJECTIVE: Hyaluronic acid has been used for a long time as a biorevitalizer to treat skin aging both in single formulation and in association with other compounds such as amino acids or vitamins. The purpose of this study was to evaluate the efficacy and safety of class III medical devices SKIN B, SKIN R, SKIN OX, SKIN COLIN, for the treatment of wrinkles on the face, neck, décolleté and hands. These medical devices are all based on hyaluronic acid and supplemented with amino acids (SKIN B and SKIN R) and glutathione (SKIN OX) or colin (SKIN COLIN). This gives broader possibilities to the aesthetic surgeon for personalization and pharmacological diversification based on the patient's deficits to treat. PATIENTS AND METHODS: A total of 60 subjects affected by skin damage such as rhytidids, dehydration, reduced sebum production and skin hypoxia were enrolled. The patients were treated with a session of mesotherapy every 7 days for 30 days, followed by other 2 sessions every 15 days for 30 days and the follow-up on day 90. The primary efficacy endpoint was evaluated by means of a 0-10 visual analog scale at day 60; the secondary efficacy endpoint was evaluated by means of a 0-10 visual analog scale at day 90. RESULTS: All patients completed the 3-month follow-up. Treatment with SKIN B, SKIN OX, SKIN COLIN and SKIN R medical devices for the prevention and treatment of wrinkles on the face, neck, décolleté and hands were associated with favorable and positive results. A clear reduction of wrinkles has been clinically observed with improvement in the texture, brightness, and turgor of the skin. No adverse events were reported. CONCLUSIONS: The medical devices SKIN B, SKIN SKIN OX, SKIN COLIN produce an aesthetic improvement in patients affected by skin defects, when administered by mesotherapy technique. This study confirms the safety and efficacy of the medical devices based on hyaluronic acid supplemented with amino acids and glutathione or colin.

RESUMO

Xanthelasma palpebrarum is a subcutaneous lesion of the lid and cause a cosmetical issue. The aim of the present study was to evaluate the atmospheric plasma treatment for the treatment of xanthelasma with an 11-year follow up. Seventy-two patients with bilateral xanthelasma and 26 patients with unilateral xanthelasma by atmospheric plasma technique known also as voltaic arc dermabrasion (VAD, Europe Medical s.r.l. Montesilvano (PE), Italy). Photographs were obtained at the baseline and after the procedure and analyzed by an independent observer. The evaluation of the results was made 2 months after this single treatment with 11 years of follow up. The subjects average age was 48.5 years (range 41-63 years). All subjects were elected for a single session for the lesion removal. The erosion is epithelialized from the lesion margins and the dermal basal cells. After 2 months from the treatment, the result was scored as 4 (clearing of lesions > 75%, complete resolution) in 66 patients for a total of 104 lesions treated; scored as 3 in 24 patients for a total of 48 lesions, and as 2 in nine patients for a total of 18 lesions. No subjects scored 0 or 1. A total of 8 lesions showed mild erythema in the treated areas for 1 month. Numerous approaches were proposed for xanthelasma exeresis such as a surgical treatment especially in case of excessively large lesions or lesions involving the medial canthus that could produce a more limited skin laxity rapidly induces a risk of ectropion. In conclusion, the effectiveness of the present investigation suggest that the atmospheric plasma is a useful therapeutic option for the treatment of xanthelasma palpebrarum.

RESUMO

The aging process causes skin modification and wrinkle formation with an alteration of the face harmony and imperfections. The aim of the present investigation was to evaluate a cross-linked hyaluronic acid enriched with glycine and proline for zygomatic malar region infiltrations. A total of twenty healthy female patients were treated for zygomatic hypotonia. The level of patients and surgeon satisfaction was evaluated by global aesthetic improvement scale (GAIS) at baseline, immediately after the procedure and at 6 months from the treatment. The healing phase was uneventful, and no complications were reported in the perioperative and follow-up periods. No significant differences were reported between patients and surgeon GAIS score (p<0.05). A significant difference of GAIS score was reported immediately after the procedure and at 6 months if compared to the baseline (p<0.05). The cross-linked hyaluronic acid enriched with glycine and proline is a useful biomaterial for zygomatic- malar augmentation with no significant local complications and a high stability and satisfaction level of the procedure.

RESUMO

After oral surgery, bacterial adhesion to suture can cause surgical site infections and delay wound healing. Microbial adherence to the suture is influenced by its physical configuration and chemical structure. The aim of this study was to compare in vivo the bacterial adhesion to two suture materials used in oral surgery: silk and monofilament expanded polytetrafluoethilene (e-PTFE). After sinus lift surgery, 15 flaps were sutured with silk (nonabsorbable, organic, braided, 4.0) and 15 were sutured with e-PTFE (nonabsorbable, synthetic, monofilament, 4.0). Seven days after surgery, bacterial adherence, in terms of percentage of the surface covered, was evaluated for each suture material by scanning electron microscope (SEM). Onto silk suture, plaque consisted of a few cocci and a higher proportion of rods and filamentous-shaped bacteria, with some mineralized plaque. Onto e-PTFE speciments, only small colonies of a few cocci or no bacteria were observed, with empty spaces between the colonies and no plaque mineralization. The surface covered by bacteria on e-PTFE specimens was significantly lower than that of silk sutures. (22.1% ±4.96% vs 54.3% ± 7.9%; P =0.0001). The results of the present study suggest that multifilament structure of silk favours a greater bacterial adherence, proliferation, and persistence, so monofilament and e- PTFE suture should be preferred in oral surgery.

RESUMO

Graphene-doping procedure represents a useful procedure to improve the mechanical, physical and biological response of several PMMA-derived polymers and biomaterials for dental applications. The aim of the study was to evaluate measure water sorption, water solubility and tolerance trough the rabbit pyrogen testing pyrogen detection of Graphene doped Poly (methyl methacrylate) (PMMA) compared with PMMA as potential materials for dental implant device. A total of 8 aged and unaged samples Graphene doped PMMA and PMMA were tested for water sorption and water solubility of the specimens. The experimental condition was evaluated according to the ISO 20795-1:2013 protocol. The biopolymer tolerance was evaluated in vivo on animals through the pyrogen detection test, acute intracutaneous and systemic irritation test. After wet conditioning both of Graphene doped PMMA and PMMA reported an increase of the weight. All the experimental samples showed a drastic low level of water sorption and solubility. Graphene doped PMMA unaged specimens showed a stability of physical and optical feature after the treatment. The Graphene doped PMMA has not shown pyrogens, an intradermal and systemic irritant effect on animals. The Graphene-doped PMMA satisfy the standard requirements and provide a physical and optical stability of the compound after the treatment. Further in vivo findings are required for future clinical application of the compound.
