RESUMO
Zirconia and polyetheretherketone (PEEK) are two biomaterials widely investigated as substitute for metals in oral prosthetic rehabilitation. To achieve a proper biomechanical behavior, the prosthetic biomaterials must ensure a good resistance to loads, as this is a crucial characteristic enabling their use in dental applications. The aim of this study was to investigate differences in the fracture resistance of different biomaterials in an experimental environment: fixed partial dentures (FPDs) screwed in a prototype of biomimetic mandible. 10 Samples of FPDs were allocated in 2 groups (A and B): Group A (n=5) involved FPDs in zirconia-ceramic, and Group B (n=5) involved FPDs in PEEK-composite. The samples were loaded by means of a three-point bending mechanical test, and the load to fracture has been evaluated generating a point-by-point graphics (speed/load and time/deformation). The samples were further analyzed by micro-computed tomography (micro-CT) and described under experimental loading conditions. Zirconia-ceramic FDPs were the samples reporting the worst results, showing a lower value of vertical displacement with respect to PEEK-based samples. The micro-CT results have further confirmed the preliminary results previously described. This in vitro study aims to give analytic data on the reliability of PEEK as a reliable and strong biomaterial for prosthetic treatments.

Bone Tissue Engineering (BTE) is a field of regenerative medicine continuously improving, thanks to the development of new biomaterials used as grafts or scaffolds for repairing bone defects. In recent years, chitosan, a natural biopolymer extracted mainly from crustacean shells, has demonstrated unique and desirable characteristics for BTE applications, such as: biocompatibility, biodegradability, and osteoconductive behavior. Additionally, the presence of numerous active amine groups in its chemical structure allows it to be easily modified. Data suggest that chitosan scaffolds are highly biomimetic, and show an interesting bioactivity, and antibacterial behavior. We have demonstrated, in a critical overview, how chitosan-based scaffolds may hold great interest for BTE applications in medical and dental applications. Future research should be focused on the use of chitosan-scaffolds combined with other biomaterials or bioactive molecules, to increase their overall regenerative potential, also in critical-sized defects. In conclusion, chitosan can be considered a promising biomaterial in BTE and clinical dentistry.

OBJECTIVES: The aim of the present study was to evaluate the influence of crestal and subcrestal implant position on development of peri-implant diseases. MATERIALS AND METHODS: The study was designed as a retrospective clinical and radiographic analysis. Implant-supported fixed dental prostheses were allocated in two groups: with the shoulder (i) placed in sub-crestal level and (ii) placed at bone level. For each patient, the following clinical variables were assessed: FMPS, FMBS, PlI, BOP, and PD. After prothesis delivery, an intraoral radiograph was obtained; this exam was performed also at 5 years of observation period. RESULTS: No statistically significant difference was found in terms of FMPS and FMBS at baseline and after 5 years follow-up (P < 0.05). A statistically significant difference was assessed between PD of control group and test group (P = 0.042). Patient-based analysis showed a 25.6% of peri-implant mucositis and 32.6% of peri-implantitis for implants placed with the shoulder in crestal position, while for implants inserted in sub-crestal position the percentage of peri-implant-mucositis and peri-implantitis were 19%; no statistically significant difference was found between groups after 5 years (P < 0.05). CONCLUSIONS: Within the limitation of the present study, the clinical and radiographic outcomes showed that the percentage of peri-implant mucositis and peri-implantitis was not statistically significant for both groups after 5 years follow-up. CLINICAL RELEVANCE: The outcomes of present study clinically demonstrated that a deep position of implant shoulder did not provide any benefits. On the contrary, it may be considered a possible risk indicator for implant diseases.

BACKGROUND: The symptomatology in Burning Mouth Syndrome (BMS) is complex and it should be considered in accordance with a biopsychosocial model. OBJECTIVES: To evaluate the multidimensional aspects of pain with a complete battery of tests and to analyse its relationship with potential predictors such as mood disorders, sleep and quality of life. METHODS: Forty patients with BMS versus an equal number of age and sex-matched healthy controls were enrolled. The VAS, SF-MPQ, BPI, PD-Q, BDI-II, STAI, PSQI, ESS, SF-36 and OHIP-14 were administered. RESULTS: The scores of the VAS, SF-MPQ, BPI, PD-Q, BDI-II, STAI, PSQI, SF-36 and OHIP-14 were statistically significantly higher in the BMS patients than the controls (p < .001**). A strongly linear correlation between pain (VAS, SF-MPQ, BPI and PD-Q) and disease onset (STAI, BDI-II, PSQI and sub-items of SF-36 and OHIP-14) was found. In the multiple regression analysis, the contributions of the BDI-II and OHIP-14 were found to be statistically significant with the SF-MPQ, PD-Q and BPI in terms of severity and interference, while the contributions of the STAI and sleep were found to be statistically significant with the SF-MPQ and BPI in terms of severity and interference, respectively. CONCLUSIONS: Pain tests are differently correlated with mood and quality of life. Therefore, a complete analysis of the patient requires several tools to better understand the multidimensional aspects of pain in BMS.

Dental anxiety is a crucial problem for dentistry because it may represent a significant risk to oral health. Different factors, whether non-cognitive (e.g., traumatic dental events) or cognitive (e.g., the patient's subjective perceptions), may cause dental anxiety. However, previous studies have assessed these factors as independent predictors of dental anxiety, without providing any exploration of potential mediational pathways. The current study assessed the role of certain cognitive dimensions (i.e., the dentist's perceived professionalism and communicational attitudes, and the patient's perceived lack of control) as mediators between traumatic dental events and dental anxiety. The sample comprised 253 patients who had accessed a public university hospital dental surgery. The mediation analysis used a structural equation modeling. Traumatic dental events were positively associated with dental anxiety but, among the cognitive factors, only lack of control was. Furthermore, lack of control mediated the relationship between traumatic dental events and dental anxiety, although this mediation was only partial. This study sheds light on the mechanisms through which non-cognitive and cognitive factors may affect dental anxiety. The clinical implications for dental practice, in terms of improving the psychological well-being of patients, are discussed.

PURPOSE: Localized amyloidosis of the tongue is a benign condition in which surgical management may be considered. The aim of the study was to review the current literature and report a case. MATERIALS AND METHODS: We searched the PubMed database for all relevant articles reporting cases of localized tongue amyloidosis published between 1980 and February 2020. In addition, we updated 1 case diagnosed and treated in our department. RESULTS: A 49-year-old male patient presented with an asymptomatic tongue nodule of the dorsum mimicking median rhomboid glossitis. The results of an incisional biopsy showed an amyloid on Congo red staining and positive findings for the κ light chain by immunohistochemical analysis. The findings of the systemic workup were negative. Therefore, a diagnosis of localized κ light-chain amyloidosis was made. The patient underwent a resection of the lesion, and no recurrence or progression was observed during a period of 18 months. The literature review showed 12 reports describing 21 patients (11 men, 52.3%) with localized tongue amyloidosis. The most common clinical presentation was nodular with a single lesion of the tongue dorsum (15 patients, 71.4%). All cases showed positive findings on Congo red staining. Immunohistochemical analysis findings were available for only 9 patients (42.8%) and showed light-chain amyloidosis. No case showed any systemic involvement or the development of systemic disease. Surgical excision was performed in 9 cases, with recurrence at the site of operation in 2 cases. CONCLUSIONS: Localized amyloidosis of the tongue is a rare disease in which surgical excision may be therapeutic when a multidisciplinary evaluation does not show any systemic disease. We recommend an excision when the lesion is persistent or shows an enlargement or when discomfort is reported. In the case of any further local recurrence, resection may be repeated.

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.

PURPOSE: To compare the clinical and patient-reported outcomes of ≤6-mm implants with those of ≥10-mm implants placed after both lateral and transcrestal sinus floor elevation. MATERIALS AND METHODS: Using PubMed (MEDLINE), EMBASE, and Cochrane, a literature search for randomized controlled trials was performed. All the outcome variables were evaluated through a quantitative meta-analysis, and the influence of other clinical covariates were determined with a metaregression. For the survival outcomes, trial sequential analysis (TSA) was performed to adjust results for type I and II errors and to analyze the power of the available evidence. RESULTS: After full-text reading, 12 studies were included in the analyses. No statistically significant difference was found after 3 years between the 2 study groups (P = 0.36). Short implants displayed fewer biological complications (P = 0.05), less marginal bone loss (MBL) from implant placement (P < 0.01), and reduced surgical time and treatment cost. However, long implants showed a statistically significant smaller number of prosthetic complications (P = 0.03). TSA confirmed the results of the meta-analysis, revealing that additional studies are needed due to low statistical power of the available evidence. CONCLUSION: The placement of short implants is a predictable option in treating patients with maxillary atrophy up to a 3-year follow-up. Studies with a longer observational period are needed to study the long-term performance of these implants.

Lack of standardization of clinically compliant culture protocols of mesenchymal stem cells for re-implantation in humans have hindered clinical progress in the field of tissue regeneration to repair maxillofacial and orthopedic defects. The goal of this study was to establish a clinically relevant osteogenic protocol for collection and expansion of autologous stem cells to be used at Marshall University for re-implantation and repair of maxillofacial and orthopedic conditions. Human bone marrow (hBM) samples were collected from patients undergoing intramedullary nail fixation for closed femoral fractures. hBM mesenchymal cells were expanded by growing them first in Petri dishes for two weeks, followed by a week of culture using Perfecta 3D Hanging Drop Plates®. Various scaffold materials were tested and analyzed for cellular integration, vitality, and differentiation capacity of harvested hBM-MSCs including: 60/40 blend of hydroxyapatite biomatrix; Acellular bone composite discs; Allowash®, cancellous bone cubes; PLGA (poly lactic-co-glycolic acid); and Woven chitin derived fiber. We found that the 3D spheroid culture allowed production of hBM mesenchymal cells that retained osteoblast differentiation capacity over a monolayer culture of hBM-MSCs without the need to use chemical or hormonal modulation. We also observed that hydroxyapatite and Allowash cancellous bone scaffolds allowed better cell integration and viability properties as compared to other materials tested in this study. In conclusion, the multimodal culture methodology we developed creates actively differentiating stem-cell spheroids that can then be readily utilized in clinical practices to improve the regeneration of tissues of the head and the body.

The authors reported their surgical experience about structural fat grafting in the management of facial volumetric deficit. The purpose of this study was to assess the real indications, cosmetic results, complications, and global patient satisfaction of the Coleman technique in redefining facial contours in congenital and postoperative deformities. A retrospective analysis of 32 patients grafted according to Coleman's technique was performed, and the long-term outcomes and patient satisfaction were evaluated. The mean postoperative clinical follow-up was 14 months. The morphological changes were analyzed by comparing the photographic presurgical facial contour and the postoperative correction of soft tissue defects. All consecutive cases reported showed a progressive fat resorption for 3 months after surgery and its stable integration only after this period. Best results were performed in the treatment of genetically determined syndromes, such as the Franceschetti and Romberg syndromes. The authors suggest this surgical technique also for the treatment of unaesthetic cutaneous abscess cavity after incision and drainage. Unsatisfactory outcomes were obtained in the treatment of the posttraumatic facial scar, which needed more surgical procedures.

Maxillary sinus augmentation is one of the most predictable procedures for the rehabilitation of the posterior maxilla. The current overview aimed to summarize the findings provided by systematic reviews (SRs) and meta-analyses on the effectiveness of autologous platelet concentrates (APCs) in sinus lift and to assess the methodological quality of the included SRs. Three electronic databases have been explored. SRs and meta-analyses addressing the effectiveness of APCs in sinus lift technique were included. Clinical, radiographic and histomorphometric findings were considered for APCs as solely grafting materials and APCs in combination with biomaterials. Outcomes were implant survival rate (ISR), implant stability (IS), implant failure (IF), postoperative complications, histomorphometric findings, radiographic bone gain, bone volume and bone density. The methodological quality of the included SRs was assessed using the updated version of "A Measurement Tool to Assess Systematic Review" (AMSTAR-2). Thirty SRs were included. The methodological quality of the included reviews ranged from critically low (3 studies) to high (9 studies). The included SRs showed favorable clinical outcomes, short-term new bone formation and no biological complications when APCs were used both as solely graft material or in combination with other biomaterials. However, no significant additional effects in the long-term period were observed. APCs did not add any further positive effects compared to the physiological healing derived by the natural blood clot. The current overview of SRs highlighted the need for high-quality SRs evaluating the role of APCs in sinus lift though network meta-analyses, in order to identify the most powerful material for sinus lift augmentation. The use of APCs improves the healing of soft tissues and the postoperative quality of life in the short-term period. Thus, its application can be recommended.
RESUMO
OBJECTIVES: This in vitro study aimed to investigate the impact of bicarbonate air-abrasive powders and ultrasonic scaling with stainless steel tips on the micro- and nanotopography and roughness of three different implant-abutment junction titanium surfaces. MATERIALS AND METHODS: Three types of sterile and decontaminated titanium surfaces (RS, UTM, XA) were used for analysis. Nine disks per surface type were subjected to micro- and nanotopography analysis, scanning electron microscopy (SEM), roughness analysis, and fibroblast cultivation. Ultrasonic debridement and air polishing were performed on the surfaces. Human dermal fibroblasts were cultured on the surfaces for 5 days. STATISTICAL ANALYSIS: Data analysis adhered to ISO 25178 standards for surface texture assessment. SEM micrographs were used to reconstruct areas for extracting roughness parameters. Excel and Mex 6.0 software were utilized for quantitative and stereoscopic analysis. RESULTS: The study found varying effects on surface roughness posttreatment. RS Disco samples exhibited higher surface roughness compared with UTM and XA samples, both in average and nanoscale roughness. Decontamination led to increased surface roughness for all samples, particularly RS Disco. Fibroblast growth tests revealed enhanced cell network formation on decontaminated discs, possibly due to increased nanoscale roughness or the presence of bicarbonate salts. CONCLUSION: The study underscores the complex interplay between surface topography, microbial biofilm, and treatment efficacy in peri-implant disease management. While smoother surfaces may resist biofilm accumulation, increased nanoscale roughness postdecontamination can enhance fibroblast attachment and soft tissue integration. This dichotomy highlights the need for tailored treatment protocols that consider material-specific factors, emphasizing that successful implant therapy should balance microbial control with conducive surface characteristics for long-term osseointegration and soft tissue stability.
RESUMO
In the industrialized part of the world, an increasing number of people live the old age without too many restrictions due to illness or physiological impairment. This group is known as the young elderly. On the contrary, a consistent part of seniors develops a greater number of medical conditions and become more and more dependent, these are the old elderly. The first cause of tooth lost in industrialized word is periodontitis that generally strikes people older than 40 years and determines serious detriment of the stomatognatic organ. Smoking and stress are risk factors for periodontitis that are common and shared between young, adult, and older age. Diabetes mellitus, obesity, and osteoporosis are very frequent pathological situations in older age. They have been identified as cofactors in the progression of periodontitis. Many dental associations recognize the importance of continued research on oral fluids diagnostics and welcome the development of rapid point-of-care tests providing accurate measurements of clinically validated biomarkers. At present, well-studied molecules associated with host response factors and with derived tissue destruction mediators have been proposed as diagnostic biomarkers for periodontitis detected in the oral fluids.

PURPOSE: To assess soft and hard tissues healing at immediate transmucosal implants placed into maxillary molar region with collagen membranes uncovered. MATERIALS AND METHODS: Twenty subjects received 20 immediate transmucosal implants placed in maxillary molar extraction sockets. Periimplant marginal defects were treated according to the principles of guided bone regeneration by means of deproteinized bovine bone mineral particles in conjunction with collagen membrane. Flaps were repositioned and sutured, allowing nonsubmerged, transmucosal soft tissues healing. The collagen membranes adapted around implant neck were uncovered. RESULTS: No implants were lost during the 1-year observation period yielding a survival rate of 100%. No postsurgical wound healing complications were observed. No degranulation of grafting material was reported. CONCLUSIONS: The results of this 12-month prospective study showed that the exposure of collagen membrane at time of the flap suturing does not represent a limitation for the soft and hard tissues healing at immediate transmucosal implants placed into maxillary molar extraction sites.

RESUMO
Oral malignant melanoma (OMM) has a prevalence less than 1% of all melanomas and it commonly develops on the oral mucosa following a slow and unspecific transformation of unstable melanocytic lesions, often resulting in a diagnostic delay. The marker PReferentially Expressed Antigen in MElanoma (PRAME) seems to be a valid tool to investigate the biological and histological nature of cutaneous melanocytic lesions, but to date its use to characterize pigmented lesions in the oral cavity is largely unexplored. The aim of this study was to create preliminary knowledge on the PRAME expression in OMM, and to compare its expression respect to other dysplastic pigmented lesions of the oral cavity. Interestingly, PRAME has been demonstrated to be reliable in the clinical conditions investigated in our pilot study; in fact, it has clearly differentiated the cases of Melanoma, which showed diffuse and intense positivity (score 6+/7+) to PRAME, from the other melanocytic nevi, which resulted to be mainly negative to PRAME. This means a better differential diagnosis, a reliable early diagnosis and a proper clinical/surgical management of the oncological lesions. In conclusion, PRAME can be a valid qualitative marker for differential diagnosis, not only in cutaneous melanomas, but also in malignant melanoma of the entire head and neck area.
RESUMO
In oral surgery, the management of patients on anticoagulant therapy is still challenging because of the risks of uncontrolled bleeding and, if the therapy is discontinued, the possibility of undesired thromboembolic complications. The use of local hemostatic agents may be a viable alternative to overcome these issues. Along these lines, the aim of this work was to evaluate the use of newly developed swelling matrices loaded with tranexanic acid in preventing postextractive bleeding in patients with no modification of oral anticoagulant therapy. The matrices are made up of cellulose and are able to fit the tridimensional postextractive alveolar cavity, thus assuring also a mechanical contribution to homeostasis. The potential of this new therapeutic approach in reducing hospitalization, removing the risk of infections, and lowering the number of hemorrhagic complications was demonstrated.

In cases of reconstruction of a discontinuity defect of the mandible, the surgeon has a major responsibility to maximize function as well as cosmetics and to preserve quality of life, restoring mastication, speech, and appearance. Treatment of mandibular discontinuity defects is a complex process and, among other methods, includes the use of free vascularized flaps. A variety of donor sites have been used for this purpose, including the iliac crest, radius, scapula, and fibula.At this time, the iliac crest free flap represents a versatile reconstruction method after mandibular ablation. This article reports a clinical case using the iliac crest free flap for comprehensive reconstruction of discontinuity defects in the mandible after resections of an aggressive odontogenic tumor. The immediate implant positioning reduced the number of surgical procedures and the rehabilitation time.

OBJECTIVE: The aim of this study was to assess the impact of lockdown due to the coronavirus COVID-19 pandemic on the periodontal status of patients with periodontitis in supportive periodontal therapy. METHOD AND MATERIALS: A retrospective analysis of patients affected by periodontitis stage III-IV-grade A, B, and C, who had their supportive periodontal therapy to September 2020, after a period of 6 months from the planned maintenance recall (March 2020) was performed. Clinical parameters full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), and probing depth (PD) were evaluated. Patients were assigned to three groups: A (nonsmokers); B (< 10 cigarettes/day); and C (> 10 cigarettes/day). Statistical analysis was used to compare intra-group and inter-group differences. RESULTS: In total, 55 subjects with the mean age of 47.7 ± 7.0 years were enrolled. The number of participants in group A and group B decreased, respectively, from 25 (45.5%) to 20 (36.4%) and from 17 (30.9%) to 13 (23.6%). The C group increased from 13 (23.6%) to 22 (40.0%). A statistically significant increase in mean FMPS was recorded in group A (from 22.5 ± 3.5 to 30.0 ± 28.3; P < .0001); group B (from 22.5 ± 12.7 to 42.5 ± 3.5; P < .0001); and group C (from 22.5 ± 25.5 to 42.5 ± 10.6; P < .0001). A statistically significant increase in mean FMBS was recorded in group A (from 15.0 ± 7.1 to 25.0 ± 21.2; P < .0001); group B (from 15.0 ± 0.0 to 37.5 ± 3.5; P < .001); and group C (from 12.5 ± 3.5 to 30.0 ± 7.1; P < .0001). A statistically significant increase in mean PD was recorded in group A (from 4.48 ± 0.5 to 5.25 ± 1.2; P < .001); in group B (from 4.71 ± 0.7 to 5.38 ± 1.31; P < .0001); and group C (from 6.00 ± 0.0 to 7.09 ± 1.1; P < .0001). CONCLUSIONS: Within the limitations of this study the results showed that the pandemic period resulted in an increase in probing depth for the patients in regular SPT, possibly due to increased tobacco consumption.

Background: An adequate blood supply plays a leading role in the healing process of the post-extractive socket; its coagulation leads to fibrin clot formation, which acts as a physical barrier able to prevent postoperative bleeding and microbial infection. The purpose of this study was to evaluate the effectiveness of antiaggregant drugs in healing post-extraction sockets compared to natural wound healing. Methods: This was a single-center prospective clinical trial. Extraction sockets allocated in healthy patients and in patients assuming antiplatelet drugs were considered. Thirty consecutive patients under (treated with/in treatment with) oral antiplatelet treatment were enrolled in the test group. In order to provide a control group, 30 consecutive patients meeting all the exclusion and inclusion criteria were enrolled. The extraction of the mono-radicular tooth was atraumatically performed without gingivoplasty or osteotomy procedures that could influence the healing process. Photographs were obtained before and immediately after surgery and at 3-, 7-, 14- and 28-days follow-up. Results: All patients assumed the prescribed therapy and their post-operative recovery was uneventful without any kind of post-extractive complications. The results of inter-group comparison show that on the third and seventh days of follow-up, the antiplatelet group expressed a statistically significant higher level of healing compared to the control group (p < 0.05), while no statistically significant differences were recorded at 14- and 28-days follow-up. Conclusions: Patients treated with antiplatelet agents seemed to show that this therapy can positively affect the healing process after tooth extractions.
