Abstract
The purpose of this study was to systematically review the randomized and non-randomized clinical trials (RCT; nRCT) concerning the different available osteotomies for surgically assisted rapid maxillary expansion (SARME): pterygomaxillary disjunction (SARME + PD vs SARME-PD) and segmental Le Fort I osteotomy (2-piece vs 3-piece). Outcomes focused on skeletal, dental, upper airway changes, complications, and relapse. Two authors investigated five databases (PubMed, Cochrane Library, Google Scholar, Scopus, Web of Science) until August 2023. The Cochrane Collaboration Tool and the Newcastle-Ottawa scale were used for the quality assessment of the included RCTs and nRCTs, respectively. A total of 554 articles were retrieved and after duplicates removing and full-text reading, 40 studies were included. Two RCTs showed a low risk of bias, one an unclear risk and one a high risk. Among the non-RCTs, 15 studies showed a good quality, while 21 exhibited a fair quality score. SARME + PD resulted in more homogeneous posterior bone expansion, with minimal dental effects. No difference between 2-piece and 3-piece in asymmetric expansion was observed, although 3SO showed 1-2 mm of more transverse increase. The oropharynx minimum cross-sectional area, the nasopharynx and the oropharynx volume were greater in SARME + PD. Both dental and bone relapse can occur but no differences between the groups were observed. All osteotomies guaranteed a correction of transverse maxillary deficiency. Lower side effects were described in SARME + PD. Two-piece and 3-piece segmental Le Fort I osteotomies did not show any differences in the symmetry and amount of expansion.

Abstract
INTRODUCTION Skeletal stability after bimaxillary surgical correction of Class III malocclusion was investigated through a qualitative and quantitative analysis of the maxilla and the distal and proximal mandibular segments using a 3-dimensional voxel-based superimposition among virtual surgical predictions performed by the orthodontist in close communication with the maxillofacial surgeon and 12-18 months postoperative outcomes. METHODS A comprehensive secondary data analysis was conducted on deidentified preoperative (1 month before surgery [T1]) and 12-18 months postoperative (midterm [T2]) cone-beam computed tomography scans, along with virtual surgical planning (VSP) data obtained by Dolphin Imaging software. The sample for the study consisted of 17 patients (mean age, 24.8 ± 3.5 years). Using 3D Slicer software, automated tools based on deep-learning approaches were used for cone-beam computed tomography orientation, registration, bone segmentation, and landmark identification. Colormaps were generated for qualitative analysis, whereas linear and angular differences between the planned (T1-VSP) and observed (T1-T2) outcomes were calculated for quantitative assessments. Statistical analysis was conducted with a significance level of α = 0.05. RESULTS The midterm surgical outcomes revealed a slight but significantly less maxillary advancement compared with the planned position (mean difference, 1.84 ± 1.50 mm; P = 0.004). The repositioning of the mandibular distal segment was stable, with insignificant differences in linear (T1-VSP, 1.01 ± 3.66 mm; T1-T2, 0.32 ± 4.17 mm) and angular (T1-VSP, 1.53° ± 1.60°; T1-T2, 1.54° ± 1.50°) displacements (P >0.05). The proximal segments exhibited lateral displacement within 1.5° for both the mandibular right and left ramus at T1-VSP and T1-T2 (P >0.05). CONCLUSIONS The analysis of fully digital planned and surgically repositioned maxilla and mandible revealed excellent precision. In the midterm surgical outcomes of maxillary advancement, a minor deviation from the planned anterior movement was observed.

Abstract
Background The standard treatment for a dentigerous cyst of maxilla is a surgical enucleation, the extraction of the tooth. In the case of cysts involving the maxillary sinus, a Caldwell-Luc approach is used. In case of large cysts, its marsupialization is carried out in order to reduce the bone defect, followed by enucleation and extraction of the tooth. Methods This is a case of a large follicular dentigerous cyst of upper jaw with 18 ectopic tooth within the maxillary sinus, treated in our Unit. Results We decided to perform a multi-portal access, the intraoral endoscopic-assisted technique; an intraoral approach has been performed, but less demolishing than the routine intraoral approach, through the anterior wall of the maxillary sinus, already eroded by the lesion. The lesion was very large, occupying the entire maxillary cavity. For this reason, by means of the intraoral approach alone, it was extremely difficult to remove the lesion in its entirety. The endoscopic-assisted technique was combined with intraoral approach. The lesion extended to the maxillary ostium. This did not allow to reach the ostium through the classic endoscopic approach. Endonasal endoscopic access was used both to enucleate the cyst, that was adherent to the orbital floor and soft tissues of the OMC (osteomeatal complex), and to restore the physiological drainage of the maxillary sinus. Conclusions We decided to perform a combined intraoral and endoscopic approach to allow a complete excision of the cystic lesion, without being very demolishing and taking advantage of the bone erosion already caused by the large cyst.

Abstract
OBJECTIVES Among the existing techniques for the correction of mandibular posterior vertical insufficiency (PVI), the intra-oral ramus vertical lengthening osteotomy (IORVLO) can be proposed as it allows simultaneous correction of mandibular height and retrusion. This study assessed the 3D morpho-anatomical changes of the ramus-condyle unit and occlusal stability after IORVLO. MATERIALS AND METHODS This retrospective analysis compared immediate and 1-year post-operative 3D CBCT reconstructions. The analysis focused on the condylar height (primary endpoint) and on the changes in condylar (condylar diameter, condylar axis angle) and mandibular (ramus height, Frankfort-mandibular plane angle, gonion position, intergonial distance, angular remodeling) parameters. Additionally, this analysis investigated the maxillary markers and occlusal stability. RESULTS On the 38 condyles studied in 21 included patients (mean age 23.7 ± 3.9 years), a condylar height (CH) loss of 0.66 mm (p < 0,03) was observed, with no correlation with the degree of ramus lengthening (mean 13.3 ± 0.76 mm). Only one patient presented an occlusal relapse of Class II, but a 3.4 mm (28%) condylar diameter loss and a 33% condylar volume reduction with loss of 1 mm and 3.4 mm in CH and condyle diameter, respectively. A mean 3.56 mm (p < 0.001) decrease in ramus height was noted, mainly due to bone resorption in the mandibular angles. CONCLUSION This study confirms the overall stability obtained with IORVLO for the correction of PVI. CLINICAL RELEVANCE This study aims to precise indication of IORVLO, and to validate the clinical and anatomical stability of results.

Abstract
The purpose of this study was to evaluate short- and long-term changes in growing patients with Class II malocclusion and open bite after rapid maxillary expansion (RME). A retrospective cohort study was conducted with 16 growing patients with open-bite malocclusion enrolled in a group treated with a rapid maxillary expander (RME) with a crib (TG), and 16 untreated patients with similar malocclusion in the control group (CG). Cephalograms were recorded before starting the treatment (T0), at the end of the latency phase (T1), and before the fixed therapy (T2) in order to analyze skeletal and dental changes in vertical, transversal, and sagittal relationships. Statistical analysis was performed with α = 0.05 as level of significance. At the end of the active expansion (T1), all subjects in the TG showed a corrected overbite with a statistically significant difference compared to the CG (p > 0.05). A significant decrease in jaw divergence was found in the TG compared to the CG (p < 0.05). At T2, all treated patients maintained a correct overbite. Statistical analysis revealed a significant decrease in maxillary, mandibular, and intermaxillary divergence in the TG compared to the CG (p < 0.05). This protocol could be effective in growing open-bite patients, showing a long-term decrease in facial divergence. The fixed crib allowed to normalize myofunctional activity.

Abstract
Emerging evidence shows that oral squamous cell carcinoma (OSCC) invasiveness can be attributed to a small subpopulation of cancer stem cells (CSCs) in the bulk of the tumor. However, the presence of CSCs in the OSCC close resection margins is still poorly unexplored. Here, we found that BMI1, CD44, SOX2, OCT4, UBE2C, CXCR4 CSCs marker genes are significantly upregulated, while IGF1-R, KLF4, ALDH1A1, CD133, FAM3C are downregulated in the tumor core vs healthy mucosa of 24 patients with OSCC. Among these, SOX2 appears also upregulated in the tumor close margin vs healthy mucosa and this significantly correlates with tumor size and lymph node compromise. In vitro analyses in CAL27 and SCC15 tongue squamous cell carcinoma cell lines, show that SOX2 transient knockdown i) promotes the mesenchymal-to-epithelial transition, ii) smooths the invasiveness, iii) attenuates the 3D tumor sphere-forming capacity, and iv) partially increases the sensitivity to cisplatin treatment. Overall, our study highlights that the OSCC close margins can retain CSC-specific markers. Notably, SOX2 may represent a useful CSCs marker to predict a more aggressive phenotype and a suitable target to prevent local invasiveness.

Abstract
PURPOSE Mandibular second molar (M2M) impaction is a serious eruption disorder. The purpose of this systematic review was to analyze the therapeutic approaches for M2M impaction. The objective of the meta-analysis was to summarize the success of the surgical, surgical-orthodontic, and orthodontic treatment. METHODS A PRISMA-guided search strategy was conducted by 2 authors in 5 databases up to January 2023. Randomized and nonrandomized clinical trials were considered. Case reports, case series with<5 patients, and reviews were excluded. Methodological quality was assessed using Newcastle-Ottawa scale and Cochrane Collaboration tool for nonrandomized and randomized clinical trials, respectively. Outcomes were as follows: 1) treatment success rate defined by the repositioning of impacted M2M in the dental arch with normal functional occlusal relationship and periodontal health; 2) time-to-repositioning as time-to-event analysis; and 3) complications. Meta-analysis examined treatment success differences with 3 approaches: orthodontic (uprighting maneuvers/traction), surgical (surgical procedures/strategic extractions), and surgical-orthodontic (combined surgical and orthodontic procedures) as the exposure variable. The quantitative analysis also compared the success rate using third molar removal as the secondary predictor variable. The χ2 test determined the statistical heterogeneity (I2); a cut-off of 70% was used to select the common or random effects model. Odds ratio (OR) and 95% confidence interval (CI) were recorded. RESULTS A total of 1,102 articles were retrieved. After full-text reading, 16 articles were included and 1008 M2Ms were analyzed. Nine studies had fair quality, 6 studies had good quality, and 1 had unclear risk of bias. Managing impacted M2Ms showed a moderate to high success rate (66.7 to 100%). Significant differences favoring surgical treatment over orthodontic treatment were observed for M2M uprighting (OR = 4.97; CI: 1.49 to 16.51; P = .01).No differences were detected comparing surgical and surgical-orthodontic treatment (OR = 1.00; CI: 0.03 to 37.44; P = .99), or orthodontic and surgical-orthodontic treatment(OR = 4.14; CI: 0.43 to 40.14; P = .22).Third molar removal showed no significant correlation with M2M uprighting (OR = 1.98; CI: 0.24 to 16.03; P = .5). CONCLUSION Despite study limitations, both orthodontic and surgical management of impacted M2M can be effective suggesting that clinicians are able to choose best treatment for most cases.

Abstract
BACKGROUND Macro-geometry and surgical implant site preparation are two of the main factors influencing implant stability and potentially determining loading protocol. The purpose of this study was to assess the initial stability of various implant macro-designs using both magnetodynamic and traditional osteotomy techniques in low-density bone. The parameters examined included peak insertion torque (PIT), implant stability quotient (ISQ), and peak removal torque (PRT). METHODS Four groups of 34 implants each were identified in accordance with the surgery and implant shape: T5 group (Five implant and osteotomy using drills); M5 group (Five implant and magnetodynamic osteotomy using Magnetic Mallet); TT group (TiSmart implant and osteotomy with drills); and MT group (TiSmart implant and magnetodynamic osteotomy). Every implant was placed into a low-density bone animal model and scanned using CBCT. The PIT and PRT were digitally measured in Newton-centimeters (Ncm) using a torque gauge device. The ISQ was analyzed by conducting resonance frequency analysis. RESULTS The PIT values were 25.04 ± 4.4 Ncm for T5, 30.62 ± 3.81 Ncm for M5, 30 ± 3.74 Ncm for TT, and 32.05 ± 3.55 Ncm for MT. The average ISQ values were 68.11 ± 3.86 for T5, 71.41 ± 3.69 for M5, 70.88 ± 3.08 for TT, and 73 ± 3.5 for MT. The PRT values were 16.47 ± 4.56 Ncm for T5, 26.02 ± 4.03 Ncm for M5, 23.91 ± 3.28 Ncm for TT, and 26.93 ± 3.96 Ncm for MT. Based on our data analysis using a t-test with α = 0.05, significant differences in PIT were observed between TT and T5 (p < 0.0001), M5 and T5 (p < 0.0001), and MT and TT (p = 0.02). Significant differences in the ISQ were found between TT and T5 (p = 0.001), M5 and T5 (p < 0.001), and MT and TT (p = 0.01). The PRT also exhibited significant differences between TT and T5, M5 and T5, and MT and TT (p < 0.0001). CONCLUSION Our data showed favorable primary implant stability (PS) values for both implant macro-geometries. Furthermore, the magnetodynamic preparation technique appears to be more effective in achieving higher PS values in low-density bone.

Abstract
Cleft lip and/or palate (CLP) is the most common congenital craniofacial anomaly and requires bone grafting of the alveolar cleft. This study aimed to develop a novel classification algorithm to assess the severity of alveolar bone defects in patients with CLP using three-dimensional (3D) surface models and to demonstrate through an interpretable artificial intelligence (AI)-based algorithm the decisions provided by the classifier. Cone-beam computed tomography scans of 194 patients with CLP were used to train and test the performance of an automatic classification of the severity of alveolar bone defect. The shape, height, and width of the alveolar bone defect were assessed in automatically segmented maxillary 3D surface models to determine the ground truth classification index of its severity. The novel classifier algorithm renders the 3D surface models from different viewpoints and captures 2D image snapshots fed into a 2D Convolutional Neural Network. An interpretable AI algorithm was developed that uses features from each view and aggregated via Attention Layers to explain the classification. The precision, recall and F-1 score were 0.823, 0.816, and 0.817, respectively, with agreement ranging from 97.4 to 100% on the severity index within 1 group difference. The new classifier and interpretable AI algorithm presented satisfactory accuracy to classify the severity of alveolar bone defect morphology using 3D surface models of patients with CLP and graphically displaying the features that were considered during the deep learning model's classification decision.

Abstract
BACKGROUND Facial swelling, pain, and trismus are the most common postoperative sequelae after mandibular third molar (M3M) surgery. Corticosteroids are the most used drugs to reduce the severity of inflammatory symptoms after M3M surgery. This study aimed to evaluate the effect of a single pre-operative dose of prednisone on pain, trismus, and swelling after M3M surgery. METHODS This study was designed as a split-mouth randomized, controlled, triple-blind trial with two treatment groups, prednisone (PG) and control (CG). All the parameters were assessed before the extraction (T0), two days (T1), and seven days after surgery (T2). Three-dimensional evaluation of facial swelling was performed with Bellus 3D Face App. A visual analogue scale (VAS) was used to assess pain. The maximum incisal distance was recorded with a calibrated rule to evaluate the trismus. The Shapiro-Wilk test was used to evaluate the normal distribution of each variable. To compare the two study groups, the analysis of variance was performed using a two-tailed Student t-test for normal distributions. The level of significance was set at a = 0.05. Statistical analysis was conducted using the software STATA (STATA 11, StataCorp, College Station, TX). RESULTS Thirty-two patients were recruited with a mean age of 23.6 ± 3.7 years, with a male-to-female ratio of 1:3. A total of 64 M3Ms (32 right and 32 left) were randomly assigned to PG or CG. Surgery time recorded a mean value of 15.6 ± 3.7 min, without statistically significant difference between the groups. At T1, PG showed a significantly lower facial swelling compared to CG (PG: 3.3 ± 2.1 mm; CG: 4.2 ± 1.7 mm; p = 0.02). Similar results were recorded comparing the groups one week after surgery (PG: 1.2 ± 1.2; CG: 2.1 ± 1.3; p = 0.0005). All patients reported a decrease in facial swelling from T1 to T2 without differences between the two groups. At T1, the maximum buccal opening was significantly reduced than T0, and no difference between PG (35.6 ± 8.2 mm) and CG (33.7 ± 7.3 mm) (p > 0.05) was shown. Similar results were reported one week after surgery (PG: 33.2 ± 14.4 mm; CG: 33.7 ± 13.1 mm; p > 0.05). PG showed significantly lower pain values compared to CG, both at T1 (PG: 3.1 ± 1.5; CG: 4.6 ± 1.8; p = 0.0006) and T2 (PG: 1.0 ± 0.8; CG: 1.9 ± 1.4; p = 0.0063). CONCLUSION Our results showed that pre-operative low-dose prednisone administration could reduce postoperative sequelae by improving patient comfort after M3M surgery and reducing facial swelling two days and one week after surgical procedures.

Abstract
In the present case-control study, the impact of medication-related osteonecrosis of the jaws (MRONJ) on patients' oral health-related quality of life (OHRQoL), overall quality of life (QoL), and psychological status was evaluated using a set of questionnaires. These questionnaires included the Oral Health Impact Profile-14 (OHIP-14), the Short Form 36 Health Survey Questionnaire (SF-36), and the hospital anxiety and depression scale (HADS). A total of 25 MRONJ patients and 25 controls were included in the study. The results showed that MRONJ patients had a significantly poorer OHRQoL (OHIP-14 score p-value: 0.003) and lower general QoL, particularly in the domains of "physical functioning", "physical role", "body pain", "general health", and "vitality" in the SF-36 questionnaire (p-values: 0.001, 0.001, 0.013, 0.001, and 0.020). Although there were no significant differences between the groups in the SF-36 domains of "social functioning", "emotional role", and "mental health", the mean sub-scores of the HADS, specifically the depression and anxiety scores (HADS-D and HADS-A), were significantly higher in MRONJ patients (p-values: 0.002 and 0.009). However, the "mental health" domain of the SF-36 questionnaire showed a correlation with both HADS-A and HADS-D scores (p-values: 0.003 and 0.031). Therefore, a comprehensive clinical examination of MRONJ patients should include the assessment of OHRQoL, overall QoL, and psychological profile using different questionnaires. This approach aims to gather detailed information about patients' physical and psychological well-being, enabling the development of tailored treatments.

Abstract
The aim of the study was to evaluate the accuracy of zygomatic implant placement using customized bone-supported laser-sintered titanium templates. Pre-surgical computed tomography (CT) scans allowed to develop the ideal virtual planning for each patient. Direct metal laser-sintering was used to create the surgical guides for the implant placement. Post-operative CT scans were taken 6 months after surgery to assess any differences between the planned and placed zygomatic implants. Qualitative and quantitative three-dimensional analyses were performed with the software Slicer3D, recording linear and angular displacements after the surface registration of the planned and placed models of each implant. A total of 59 zygomatic implants were analyzed. Apical displacement showed a mean movement of 0.57 ± 0.49 mm on the X-axis, 1.1 ± 0.6 mm on the Y-axis, and 1.15 ± 0.69 mm on the Z-axis for the anterior implant, with a linear displacement of 0.51 ± 0.51 mm on the X-axis, 1.48 ± 0.9 mm on the Y-axis, and 1.34 ± 0.9 mm on the Z-axis for the posterior implant. The basal displacement showed a mean movement of 0.33 ± 0.25 mm on the X-axis, 0.66 ± 0.47 mm on the Y-axis, and 0.58 ± 0.4 mm on the Z-axis for the anterior implant, with a linear displacement of 0.39 ± 0.43 mm on the X-axis, 0.42 ± 0.35 mm on the Y-axis, and 0.66 ± 0.4 mm on the Z-axis for the posterior implant. The angular displacements recorded significative differences between the anterior implants (yaw: 0.56 ± 0.46°; pitch: 0.52 ± 0.45°; roll: 0.57 ± 0.44°) and posterior implants (yaw: 1.3 ± 0.8°; pitch: 1.3 ± 0.78°; roll: 1.28 ± 1.1°) (p < 0.05). Fully guided surgery showed good accuracy for zygomatic implant placement and it should be considered in the decision-making process.

Abstract
Background The use of dental implants in the prosthetic rehabilitation of the posterior atrophic maxilla might be a challenge procedure because of low bone quantity and quality. This study aimed to report cases of implant displacement or migration into the maxillary sinus treated from 2008 to 2021. Materials and methods All patients with unintentional insertion and/or displacement of dental implants into the maxillary sinus cavity that underwent surgical removal were included. Variables assessed included the patients’ characteristics, past medical history, clinical and radiological findings at presentation, surgical approach (transoral, transnasal, combined), and outcome. Results A total of forty patients (23 male, 17 female) underwent surgical removal of dental implant displaced in the maxillary sinus. The mean age was 52,3 + 11,3 years. Seven patients presented with oro-antral fistula (OAF). In 15 cases, an ostium obstruction was diagnosed. Twenty-five patients underwent transoral surgery under local anesthesia. Eleven patients were treated solely via transnasal endoscopic approach, and four patients who had an associated OAF underwent surgery through a combined transnasal and transoral approach. All patients healed uneventfully without complications. Conclusion These results and recent literature validate that transoral and transnasal approach, or a combination of these procedures, can be used safely to treat complications following displacement/migration of dental implants in the maxillary sinus. Early surgical removal minimizes sinus inflammation and prevents more invasive procedures. Each procedure presents specific indications that must be carefully evaluated prior to treatment choice to optimize intervention outcomes.

Abstract
PURPOSE This study aimed to evaluate the morphometric changes in the position of the mandibular condyles before and after orthognathic surgery. METHODS A retrospective single-center cohort study was conducted and included patients with a presurgical (T1) and postsurgical (T2) Cone Beam computed tomography (CBCT). The primary predictor variable was the orthognathic surgical treatment. Pre-operative and post-operative CBCT scans were superimposed using voxel-based registration. Semitransparent overlays of the models of condylar regions at T1 and T2 were created for the qualitative analysis. The primary outcome variable was the quantitative displacement of condyles (CoR; CoL) analyzed in X, Y, Z axis and the 3D distances. Descriptive and bivariate statistical analysis was performed, setting α=0.05. RESULTS The study sample included 33 patients (mean age: 25.33±2.49 years) affected by skeletal class III malocclusion with or without skeletal asymmetry. The X-axis showed a mean movement of 0.25 ± 0.17 mm for CoR, and 0.52 ± 0.51 mm for CoL. The Y-axis showed a mean movement of 0.29 ± 0.2 mm for CoR, and 0.51 ± 0.8 mm for CoL. The Z-axis was 0.33 ± 0.2 mm for CoR, and 0.5 ± 0.49 mm for CoL. No statistically significant difference was calculated comparing the movement of condylar surface between asymmetric and not asymmetric patients (p = 0.26 for CoR; p = 0.13 for CoL). No statistically significant difference was found in intercondylar distance between T1 and T2 (p = 0.39). CONCLUSION No statistically nor clinically significant condylar displacement are recorded in orthognathic surgery patients at 12 to 18 months of follow-up.

Abstract
Objective Condylar resorption (CR) is one of the major post-surgical complications of orthognathic surgery. This systematic review (SR) aimed to evaluate epidemiological data, risk factors, and therapeutical management of CR. Methods Six databases were screened by two investigators until September 2020 to obtain all SRs. After reading the titles and abstracts, eligible SRs were determined and data extraction was performed. Using the latest version of A Measurement Tool to Assess Systematic Reviews, the methodological quality of the included SRs was determined. Results Ten SRs with low or critically-low methodological quality were included in this review. Mandibular hypoplasia on the sagittal plane and hyperdivergent growth pattern on the vertical plane were the most common skeletal alterations in which CR could occur after orthognathic surgery. Post-operative condylar changes were analyzed both on two-dimensional and three-dimensional (3D) radiographic examinations. The incidence of CR was not related to the fixation method. Based on the severity of the pathological conditions, management of CR can include conservative or surgical therapy. Conclusions Despite the limited evidence in literature, CR is considered a consequence of orthognathic surgery. However, an accurate diagnosis of CR and a better orthognathic surgical planning must include 3D radiographic examinations to improve pre- and post-surgical comparison. Well-designed studies with long-term follow-up and 3D data are needed to clarify the findings of this analysis..

Abstract
This systematic review aimed to answer the question: “Is the use of magnetic mallet effective in oral and implant surgery procedures in terms of tissue healing, surgery outcome, and complication rate compared to traditional instruments?” A literature search of PubMed, Scopus, and Web of Science databases (articles published until 1 October 2021) was conducted, in accordance with the PRISMA statement, using the keywords “magnetic mallet”, “electric mallet”, “oral surgery”, “implantology”, and “dental implant”. Of 252 articles, 14 were included in the review (3 for teeth extraction, and 11 for implant dentistry). Out of a total of 619 dental extractions (256 patients) performed with the magnetic mallet (MM), no complications were reported. Implants inserted totaled 880 (525 patients): 640 in the MM groups (382), and 240 in control groups (133). The survival rate of implants was 98.9% in the MM groups, and 95.42% in the control groups. Seven patients experienced benign paroxysmal positional vertigo after implant surgery, all in control groups. Results are not sufficient to establish the effectiveness of MM in oral and implant surgery procedures. Randomized controlled trials with a large sample size are needed.

Abstract
Abstract
Background
Chronic kidney disease (CKD) is a serious debilitating condition affecting 10% of the world's population, yet it remains largely under recognised even among patients with pre-existing comorbidities. Approximately 5% of patients with CKD have a history of heart failure (HF), however factors associated with undiagnosed CKD in patients with multimorbidity remain unclear.
Purpose
REVEAL-CKD is a multinational initiative to assess undiagnosed CKD. This analysis aims to assess prevalence and factors associated with undiagnosed stage 3 CKD in patients with heart failure.
Methods
From the US, we utilised TriNetX, a federated research network providing statistics on electronic health records. Adult patients, with two consecutive estimated glomerular filtration rate (eGFR) measurements ≥30 and <60 mL/min/1.732 at least 90 days apart were identified between 2015–2020. HF status was ascertained by ICD codes prior to the index date (date of the second eGFR measurement). Patients with no ICD code for CKD at any time before or up to 6 months after the index date were considered to have undiagnosed CKD.
Results
The study cohort included 31,263 patients with eGFR values indicating stage 3 CKD and pre-existing HF with mean age of 72 years (standard deviation: 11 years). The overall prevalence of undiagnosed CKD was 48.5% (n=15,159, 95% Confidence Interval: 47.9–49.0). Prevalence of undiagnosed CKD increased with age, was greater than 50% in female patients and was between 38% and 46% in patients with other pre-existing comorbidities (Table 1). Compared to patients with diagnosed CKD, the undiagnosed group had more females (41% versus 60%) and a had higher proportion of patients in the older age group (≥75 years: 43% versus 52%). Fewer undiagnosed CKD patients had pre-existing comorbidities than those with diagnosed CKD.
Conclusion
This study suggests that a large proportion of either older or female patients with baseline HF comorbidity have undiagnosed CKD. These results suggest that an opportunity exists for more proactive CKD diagnosis and monitoring of patients with comorbidities

Abstract
Lower third molars (M3M) are the most frequent impacted teeth. The aim of this study was to evaluate the correlation between M3M position and gonial angle. A retrospective cross-sectional study was conducted. The study population included patients with unilateral or bilateral M3M and underwent Cone Beam Computed Tomography. A morphometric analysis of the mandible was performed after three-dimensional reconstruction, recording gonial angle (GA), ramus high, ramus width, ramus divergency, and retromolar space. GA was the primary predictor variable. The primary outcome variable was the position of M3M analyzed in sagittal, axial, and coronal planes. Descriptive, bivariate, and multiple regression statistics were performed (p < 0.05). Study sample included 172 patients (mean age: 26.3 ± 4.6 years); 266 M3Ms were analyzed. The average GA was 122.6° ± 4.8°. A reduced GA value was significantly associated with a deeply impacted M3M in the ramus. With a progressive decrease of GA, M3M assumed a more horizontal position closer to the mandibular canal (p < 0.05). A lower GA showed a reduced retromolar space with more complex impacted M3M (p < 0.05). The results confirm a statistically significant correlation between GA and the position of M3M. Higher incidence of impacted M3M was related to a reduction of the GA value.

Abstract
STUDY QUESTION Is the microRNA (miRNA) expression pattern of cumulus oophorus cells (COCs) in women undergoing medically assisted reproduction (MAR) procedures differentially modulated according to patient age and gonadotropin treatment strategy? SUMMARY ANSWER Maternal age is an independent factor impacting miRNA expression in COCs while gonadotropin treatment may affect follicular miRNA expression and IVF efficacy. WHAT IS KNOWN ALREADY Epigenetic mechanisms in female infertility are complex and poorly studied. DNA methylation, histone modifications, miRNAs and nucleosome positioning influence cellular machinery through positive and negative feedback mechanisms either alone or interactively. miRNAs are important regulators during oogenesis, spermatogenesis and early embryogenesis, and are reported to play a role in regulating crosstalk between the oocyte and COCs. Although miRNome analysis has been performed in female human reproductive tissues (endometrium, myometrium, cervix and ovaries), epigenetic modifications in women with infertility have not been explored in detail. In addition, the impact of gonadotropin treatments during MAR on miRNA expression in COCs has not been fully investigated. STUDY DESIGN, SIZE, DURATION This study was carried out in 53 COC samples obtained from mature metaphase II (MII) oocytes in 53 women undergoing MAR treatment. A total of 38 samples for assay development were pooled by maternal age and gonadotropin treatment into four predetermined subgroups: ≥36 years and recombinant human FSH (r-hFSH), n = 10; ≥36 years and r-hFSH+ recombinant human-luteinizing hormone (r-hLH), n = 10; ≤35 years and r-hFSH, n = 9; ≤35 years and r-hFSH+r-hLH, n = 9. miRNome profiles were determined and compared between subgroups. Expression of defined miRNAs was validated in the remaining fifteen samples, representative of each subgroup, by quantitative polymerase chain reaction (PCR). PARTICIPANTS/MATERIALS, SETTING, METHODS COCs were processed for miRNA-enriched total RNA extraction and pooled in homogeneous subgroups to obtain a sufficient amount and quality of starting material to perform the analysis. Each pooled sample underwent miRNA profiling using PCR assay system to examine expression of 752 human miRNAs without pre-amplification. Data were analyzed using the delta-delta Ct method for relative quantitation and prediction of target genes (with at least four algorithms predicting the same miRNA-gene interaction pair (HIT)>4). The miRSystem database provided functional annotation enrichment (raw P-value <0.05) of co-expressed miRNAs. MAIN RESULTS AND THE ROLE OF CHANCE We found distinctive miRNA expression profiles in each subgroup correlating with age and MAR stimulation. In addition, a number of selective and co-expressed miRNAs were revealed by comparative analysis. A cluster of 37 miRNAs were commonly but differentially expressed in all four pools. Significant differences were observed in expression regulation of 37 miRNAs between age groups (≤35 or ≥36) in women receiving r-hFSH+r-hLH compared to those receiving r-hFSH alone. Higher concentrations and increased numbers of miRNAs were recorded in younger than in older patients, regardless of treatment. Functional and expression studies performed to retrieve common miRNome profiles revealed an enrichment of biological functions in oocyte growth and maturation, embryo development, steroidogenesis, ovarian hyperstimulation, apoptosis and cell survival, glucagon and lipid metabolism, and cell trafficking. The highest scored pathways of target genes of the 37 common miRNAs were associated with mitogen-activated protein kinase (MAPK) signaling pathways, G alpha signaling, transcription regulation, tight junctions, RNA polymerase I and III, and mitochondrial transcription. We identified a potential age- and MAR stimulation-dependent signature in the miRNA landscape of COCs. LIMITATIONS, REASONS FOR CAUTION We cannot rule out the possibility that other unknown individual genetic or clinical factors may have interfered with the reported results. Since miRNA profiling was conducted with a predefined array of target probes, other miRNA molecules, potentially modulated by age and hormonal stimulation, may have been missed in this study. WIDER IMPLICATIONS OF THE FINDINGS miRNA expression in COCs is modulated by gonadotropin treatment and correlates strongly with age. A better understanding of the expression patterns and functions of miRNAs may lead to the development of novel therapeutics to treat ovarian dysfunction and improve fertility in older women.

Abstract
The LABEC laboratory, the INFN ion beam laboratory of nuclear techniques for environment and cultural heritage, located in the Scientific and Technological Campus of the University of Florence in Sesto Fiorentino, started its operational activities in 2004, after INFN decided in 2001 to provide our applied nuclear physics group with a large laboratory dedicated to applications of accelerator-related analytical techniques, based on a new 3 MV Tandetron accelerator. The new accelerator greatly improved the performance of existing Ion Beam Analysis (IBA) applications (for which we were using since the 1980s an old single-ended Van de Graaff accelerator) and in addition allowed to start a novel activity of Accelerator Mass Spectrometry (AMS), in particular for 14C dating. Switching between IBA and AMS operation became very easy and fast, which allowed us high flexibility in programming the activities, mainly focused on studies of cultural heritage and atmospheric aerosol composition, but including also applications to biology, geology, material science and forensics, ion implantation, tests of radiation damage to components, detector performance tests and low-energy nuclear physics. This paper describes the facilities presently available in the LABEC laboratory, their technical features and some success stories of recent applications.

Abstract
OBJECTIVES Oral lichen planus (OLP) is a chronic immune-mediated disease that affects the oral cavity. Topical steroids are considered the treatment of choice for painful lesions of OLP. The aim of this split-mouth study was to compare the efficacy of platelet-rich fibrin (PRF) and triamcinolone acetonide (TA) injective therapies in patients with symptomatic OLP. MATERIALS AND METHODS Participants with symptomatic OLP were recruited in the Academic Hospital of Magna Graecia University of Catanzaro, Italy. Once a week for a month, patients randomly received a 0.5-mL TA injection in one buccal mucosa and 1-mL PRF injection in the opposite side. The measured outcomes were reduction of the lesions area and symptomatology modifications using visual analogue scale (VAS) score RESULTS: Four weeks after the last injections, an average reduction of 59.8% in the lesion extension and an average reduction of 47.6% in the VAS score for PRF-treated sites were observed; the same variation for TA-treated sites was respectively of 59.2% and 40%. There were no statistically significant differences between the two groups. CONCLUSIONS PRF was effective in reducing OLP lesions extension and symptomatology, and it seems to be as effective as TA. Additional data should be collected with a larger sample size, at a longer follow-up and on the PRF lowest effective dose. CLINICAL RELEVANCE Current treatment options for OLP are limited. The study proved benefits of PRF injections in management of painful lesions of OLP comparable with TA.

Abstract
Surgery-first approach (SFA) has been introduced as an alternative for conventional orthognathic approach (COA) in the treatment of patients with dentoskeletal deformities. This review aimed to evaluate skeletal stability, treatment time, surgical complications, and quality of life in SFA and COA. Six databases were accessed up to May 2020 to obtain all systematic reviews (SRs). After title and abstract reading, data extraction was performed from eligible SRs. The methodological quality was calculated for the included SRs using the last version of A Measurement Tool to Assess Systematic Review (AMSTAR-2). Ten SRs were included in this review. A good stability of the jaws was assessed both with SFA and COA by most of low- or critically low-quality SRs. Less treatment time was reported for SFA than COA with a moderate quality level. Slightly higher complications rate was recorded with SFA than COA by SRs with low or moderate quality. A better quality of life with SFA than COA was reported by moderate- or low-quality SRs. SFA may represent a reasonable alternative to COA. However, for the heterogeneity of the included SRs, well-designed studies with a long term follow-up are needed to clarify the findings of this analysis.

Abstract
OBJECTIVES The purpose of this study was to evaluate clinical efficacy of four different local hemostatics in patients taking oral antiplatelet therapy, after multiple dental extractions without discontinuing drugs. MATERIALS AND METHODS Study sample included 102 patients (mean age 64.1 ± 17.4 years) in treatment with oral antiplatelet agents needing multiple dental extractions. After surgery, the sockets were randomly sealing with suture alone (control group), hemostatic plug (HEM), advanced platelet-rich fibrin (A-PRF+), and leukocyte-platelet-rich fibrin (L-PRF). Primary outcomes were post-operative bleeding, wound healing index, and possible complications. Secondary outcomes were correlation between primary outcomes and patient's comorbidities and voluptuous habits. Descriptive statistics, bivariate comparisons, and logistic regression analysis were performed (p < 0.05). RESULTS Both A-PRF+ and L-PRF showed a reduced bleeding risk when compared with suture alone (OR = 0.09, p = 0.001 for A-PRF+; OR = 0.09, p = 0.005 for L-PRF). Only L-PRF showed a reduced risk for incomplete wound healing when compared with the control site (OR = 0.43, p = 0.019). Patients affected by hypertension (OR 3.91, p = 0.015) and diabetes (OR 3.24, p = 0.026) had the highest bleeding risk. Smoking (OR 4.30, p = 0.016) and diabetes (OR 3.79, p = 0.007) interfered with healing process. CONCLUSION L-PRF and A-PRF represent a valid alternative to the traditional hemostatics, reducing post-surgical bleeding and promoting wound healing. CLINICAL RELEVANCE In patients taking antiplatelet drugs, different local hemostatics are useful to control potential post-operative bleeding and to favor wound healing. However, comorbidities and voluptuous habits may increase bleeding risk, interfering with healing process.

Abstract
AIM The aim of the study was to investigate hyoid bone anomalies in patients with Pierre Robin sequence (PRS) compared to the control group, using computed tomography (CT) examination and three-dimensional reconstruction of the hyoid bone and mandible. METHODS A retrospective study was performed of patients between birth and 12 months old with isolated PRS (i-PRS) and syndromic PRS (ni-PRS), who had undergone CT examination, and whose results were compared to the control group of the same age. DICOM data was processed to highlight bone tissue. The mandible and hyoid bones were the main targets of the three-dimensional reconstruction. The study outcomes were the analysis of hyoid bone ossification, volume, and position (distance between hyoid and mandibular symphysis). Univariate and multivariate statistical analyses were performed with α=0.05 as level of significance. RESULTS The study sample included 29 i-PRS and 21 ni-PRS patients, while 43 infants in the control group. Hyoid ossification was present in 26/50 (52%) PRS patients (14 i-PRS; 12 ni-PRS) but in 31/43 controls (72%). Statistical analysis showed that absence of hyoid ossification was significantly associated with the diagnosis of PRS (P<0.05). Only ni-PRS patients showed a significant reduction of the distance between hyoid and mandible compared to the control group (P<0.001). Hyoid volume was significantly lower only in the ni-PRS group than in controls (P<0.001). CONCLUSION I-PRS and ni-PRS patients differ both etiologically and clinically. Ni-PRS patients confirmed their worst clinical condition than i-PRS with severe anomalies of hyoid development, helping for their ontogeny classification.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy of platelet-rich fibrin (PRF) after bone surgery compared to surgery alone in the treatment of medication-related osteonecrosis of the jaw (MRONJ). STUDY DESIGN A total of 47 patients with diagnosis of stage II or III of MRONJ were recruited at the Academic Hospital of Magna Graecia University of Catanzaro and allocated to 2 groups: In the first, patients were treated with PRF in addition to surgery (PRF group), in the other, only bone surgery was performed (non-PRF group). Fisher's exact and Student t tests were used to evaluate differences between the 2 surgical protocols in terms of mucosal integrity, absence of infection, and pain evaluation at scheduled follow-ups of 1 month (T1), 6 months (T2), and 1 year (T3). RESULTS Analysis of mucosal integrity, absence of infection, and pain evaluation showed a significant difference between the 2 groups in favor of PRF only at T1 (P < .05), whereas no differences were determined at T2 and T3 (P > .05). CONCLUSIONS Our results suggested that local application of PRF after bone surgery may improve the quality of life limited to the short-term follow-up and reduce pain and postoperative infections.

Abstract
This report describes a case of local pyoderma gangrenosum that was treated with short-term immunosuppressive therapy and the topical application of platelet-rich fibrin (PRF). Medical treatment included oral corticosteroid therapy and topical treatment with PRF in solid and liquid form. This therapy initially led to the reduction of the ulcer's size and an improvement in symptoms, until the ulcer was completely healed after a few weeks. A relapse was treated with only the application of PRF to the affected tissue with excellent recovery. The efficacy of PRF as a guide for wound healing is a result of the continuous release of growth factors involved in tissue repair mechanisms. PRF has proved to be suitable for the management of facial pyoderma gangrenosum while allowing a reduction in systemic corticosteroid therapy. The ease of preparation, low cost, and outpatient use make PRF an optimal scaffold for tissue healing processes.

Abstract
PURPOSE The main limitation of surgical treatment of medication-related osteonecrosis of the jaw (MRONJ) is difficulty in defining resection margins. The aim of this study was to compare the efficacy of the surgeon's experience and autofluorescence-guided bone surgery to delimit resection margins for necrotic bone. MATERIALS AND METHODS MRONJ requiring surgical treatment was classified according to American Association of Oral and Maxillofacial Surgeons staging. To detect vital bone and resection margins, patients of each stage were randomly assigned to 1 of 2 surgical groups: an autofluorescence-guided surgery (AF) group and a conventional surgery (non-AF) group based on the surgeon's experience. Bone samples from the 2 groups were analyzed histopathologically. The main outcomes were defined as the absence of bone exposure or infection at the time of evaluation. Infection was defined as the presence of swelling, pain, or numbness in the area. Measurements were collected preoperatively and 1 week, 1 month, 6 months, and 1 year after surgery. Statistical analysis included descriptive statistics and the Fisher exact test to evaluate eventual differences between the 2 surgical protocols. RESULTS The 36 patients (21 women and 15 men) included in this study were equally divided into 2 groups according to the surgical protocol: 18 patients in the non-AF group and 18 in the AF group. Thirty-nine lesions were included in this analysis: 20 lesions in the non-AF group and 19 in the AF group. Histopathologic examination confirmed the necrotic nature of all bone samples. Statistical analysis showed no differences in necrotic bone exposure or signs of infections between the 2 surgical protocols at different times (P > .05). CONCLUSIONS Although the VELscope appears to be useful in guiding bone resection margins in patients with MRONJ, autofluorescence does not appear to be superior to conventional surgical techniques in mucosal healing and quality of life.

Abstract
Transparent and removable aligners represent an effective solution to correct various orthodontic malocclusions through minimally invasive procedures. An aligner-based treatment requires patients to sequentially wear dentition-mating shells obtained by thermoforming polymeric disks on reference dental models. An aligner is shaped introducing a geometrical mismatch with respect to the actual tooth positions to induce a loading system, which moves the target teeth toward the correct positions. The common practice is based on selecting the aligner features (material, thickness, and auxiliary elements) by only considering clinician's subjective assessments. In this article, a computational design and engineering methodology has been developed to reconstruct anatomical tissues, to model parametric aligner shapes, to simulate orthodontic movements, and to enhance the aligner design. The proposed approach integrates computer-aided technologies, from tomographic imaging to optical scanning, from parametric modeling to finite element analyses, within a 3-dimensional digital framework. The anatomical modeling provides anatomies, including teeth (roots and crowns), jaw bones, and periodontal ligaments, which are the references for the down streaming parametric aligner shaping. The biomechanical interactions between anatomical models and aligner geometries are virtually reproduced using a finite element analysis software. The methodology allows numerical simulations of patient-specific conditions and the comparative analyses of different aligner configurations. In this article, the digital framework has been used to study the influence of various auxiliary elements on the loading system delivered to a maxillary and a mandibular central incisor during an orthodontic tipping movement. Numerical simulations have shown a high dependency of the orthodontic tooth movement on the auxiliary element configuration, which should then be accurately selected to maximize the aligner's effectiveness.

Abstract
Dedicated imaging methods are among the most important tools of modern computer-aided medical applications. In the last few years, cone beam computed tomography (CBCT) has gained popularity in digital dentistry for 3D imaging of jawbones and teeth. However, the anatomy of a maxillofacial region complicates the assessment of tooth geometry and anatomical location when using standard orthogonal views of the CT data set. In particular, a tooth is defined by a sub-region, which cannot be easily separated from surrounding tissues by only considering pixel grey-intensity values. For this reason, an image enhancement is usually necessary in order to properly segment tooth geometries. In this paper, an anatomy-driven methodology to reconstruct individual 3D tooth anatomies by processing CBCT data is presented. The main concept is to generate a small set of multi-planar reformation images along significant views for each target tooth, driven by the individual anatomical geometry of a specific patient. The reformation images greatly enhance the clearness of the target tooth contours. A set of meaningful 2D tooth contours is extracted and used to automatically model the overall 3D tooth shape through a B-spline representation. The effectiveness of the methodology has been verified by comparing some anatomy-driven reconstructions of anterior and premolar teeth with those obtained by using standard tooth segmentation tools.

Abstract
Chronic wounds represent a particular debilitating health care problem, mainly affecting elderly people. A full and correct diagnosis of tissue damage should be carried out considering both dimensional, chromatic, and thermal parameters. A great variety of methods have been proposed with the aim of producing objective assessment of skin lesions, but none of the existing technologies seem to be robust enough to work for all ulcer typologies. This paper describes an innovative and non-invasive system that allows the automatic measurement of non-healing chronic wounds. The methodology involves the integration of a three-dimensional (3D) optical scanner, based on a structured light approach, with a thermal imager. The system enables the acquisition of geometrical data, which are directly related to chromatic and temperature patterns through a mapping procedure. Damaged skin areas are detected by combining visible and thermal imaging. This approach allows for the automatic measurement of extension and depth of ulcers, even in the absence of significant and well-defined chromatic patterns. The proposed technology has been tested in the measurement of ulcers on human legs. Clinical tests have demonstrated the effectiveness of this methodology in supporting medical experts for the assessment of chronic wounds.

Abstract
Dimethyltin (DMT) is one of several organotins that are detected in domestic water supplies due to their use as plastic stabilizers for polyvinyl chloride (PVC) and chlorinated PVC (CPVC) products. A limited number of in vitro and in vivo studies suggest that DMT may produce developmental neurotoxicity; therefore, we initiated studies to evaluate long-term neurobehavioral changes in offspring following perinatal exposure. In the first study, female Sprague-Dawley rats were exposed via drinking water to DMT (0, 3, 15, 74 ppm) before mating and throughout gestation and lactation. Male offspring were tested for changes in: 1) preweaning learning in an associative runway task, 2) motor activity ontogeny, 3) spatial learning and retention in the Morris water maze as adults, 4) brain weight, 5) biochemical evidence of apoptosis, and 6) neuropathology. DMT toxicity was expressed as depressed maternal weight gain (74 ppm), and in the offspring, decreased brain weight (3, 74 ppm), decreased apoptosis (all concentrations), mild vacuolation in adult offspring (all concentrations), and slower learning in the water maze (15 ppm) due to altered spatial search patterns. In a second study, DMT exposure (same concentrations) occurred from gestational day 6 to weaning. Male and female offspring were tested. The high concentration again depressed maternal weight gain, decreased offspring birth weight and preweaning growth, and decreased brain weight. Increased and decreased apoptotic markers were measured, depending on age. Learning deficits were observed in the runway at postnatal day 11 (15, 74 ppm) and again in the adult offspring in the water maze (15 ppm). The results of both studies demonstrate a reproducible effect of 15 ppm perinatal DMT exposure on spatial learning. Changes in expression of apoptosis, brain weight, and the occurrence of neuropathological lesions also indicate potential neurotoxicity of DMT. These results were in contrast to earlier findings with monomethyl tin, for which only similar neuropathological lesions were observed. Thus, developmental neurotoxicity may be produced in offspring following gestational exposure to DMT in drinking water.

Abstract
In vivo exposure levels for neurotoxicants are often reported in parts per million (ppm) concentration in tissue, whereas exposure levels in experiments utilizing in vitro models are most commonly reported in micromolar (muM) concentration in the exposure solution. The present experiments sought to determine whether or not in vitro solution concentration was an appropriate dose-metric for comparison to in vivo tissue levels for lipophilic compounds. To do so, the accumulation of the polychlorinated biphenyl (PCB) mixture Aroclor 1254 (A1254) or methylmercury (MeHg) was examined in three commonly utilized in vitro neuronal tissue models: nerve growth factor differentiated pheochromocytoma (PC12) cells, primary cultures of rat neocortical cells, and adult rat hippocampal slices. Tissues were exposed to A1254 (0.65 ppm) or to MeHg (0.0033-0.33 ppm) in serum-free media for 1 or 24 h. Total PCB or mercury accumulation was measured by dual column gas chromatography with electron capture detection or by cold vapor atomic absorption, respectively. PC12 cells accumulated 66.7 and 103.8 ppm PCBs after 1 and 24 h exposure to A1254. Neocortical neurons also accumulated significant concentrations of PCBs, but less so than PC12 cells. After 1 h exposure to 0.65 ppm A1254, slices contained 3.46 and 0.81 ppm PCBs when exposed in a static and perfused system, respectively. After 1 h exposure to 0.0033, 0.033, and 0.33 ppm MeHg, PC12 cells contained 0.3, 2.2, and 17.7 ppm mercury, respectively; after 24 h, PC12 cells contained 0.4, 2.8, and 21.9 ppm. Hippocampal slices accumulated 1.7 and 4.8 ppm mercury after 1 and 3 h exposure to 0.33 ppm MeHg. For comparison, mercury accumulation in rat fetal and pup brain tissue after maternal exposure [0, 0.1, 1.0, or 2.0 mg/kg/day MeHg from gestational day (GD) 6-15] ranged from 0.05 to 7.89 ppm in 0.1 mg/kg dose animals on postnatal day 10 and 2.0 mg/kg dose animals on GD16, respectively. These results demonstrate that accumulation of PCBs and MeHg in vitro is tissue-, time-, and concentration-dependent and indicates that tissue levels rather than exposure concentrations are a more appropriate metric for comparison of in vitro to in vivo effects.
