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.

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..

Periodontitis is characterized by low-grade inflammation of the periodontal tissues, the structures that support and connect the teeth to the maxilla and mandible. This inflammation is caused by the accumulation of subgingival bacterial biofilm and gradually leads to the extensive damage of these tissues and the consequent loss of teeth. Hepatitis B is a major global health concern; infection with the hepatitis B virus causes significant inflammation of the liver and the possibility of its gradual evolution to cirrhosis. Hepatitis D, caused by infection with the delta hepatitis virus, is manifest only in patients already infected with the type B virus in a simultaneous (co-infected) or superimposed (superinfected) manner. The dental and periodontal status of patients with hepatitis B/D could exhibit significant changes, increasing the risk of periodontitis onset. Moreover, the progression of liver changes in these patients could be linked to periodontitis; therefore, motivating good oral and periodontal health could result in the prevention and limitation of pathological effects. Given that both types of diseases have a significant inflammatory component, common pro-inflammatory mediators could drive and augment the local inflammation at both a periodontal and hepatic level. This suggests that integrated management of these patients should be proposed, as therapeutical means could deliver an improvement to both periodontal and hepatic statuses. The aim of this review is to gather existing information on the proposed subject and to organize significant data in order to improve scientific accuracy and comprehension on this topic while generating future perspectives for research.

Background: Squamous cell carcinoma (SCC) is one of the most common cancers involving skin and oral mucosa. Although this condition’s gold-standard treatment is the surgical removal of the lesions, the physician must propose alternative treatments in some cases due to the patient’s ineligibility for surgery. Among the available alternative therapies, local chemotherapy may represent an initial treatment in combination with radiotherapy or systemic chemotherapy due to the low frequency of side-effects and the lack of necessity for expensive devices. Methods: In this paper, we review all available literature in various databases (PubMed, Scopus-Embase, Web of Science), proposing local chemotherapy as a treatment for cutaneous and oral SCC. Exclusion criteria included ocular lesions (where topical treatments are common), non-English language, and non-human studies. Results: We included 14 studies in this review. The majority were case reports and case series describing the treatment of non-resectable localized SCC with either imiquimod or 5-fluorouracil. We also analyzed small studies proposing combination treatments. Almost all studies reported an excellent clinical outcome, with a low risk of relapses in time. Conclusions: Resection of the lesion remains the gold-standard treatment for SCC. When this approach is not feasible, local chemotherapy may represent a treatment alternative, and it may also be associated with radiotherapy or systemic chemotherapy.

Poor oral hygiene leads to the accumulation of dental plaque, thus contributing to the initiation of periodontal disease (PD). Local infections can lead to systemic inflammatory responses, which are essential mediators for the evolution of systemic conditions or cancer tumorigenesis. Often, patients hospitalized with life-threatening and incapacitating disorders such as gastric cancer (GC) might lose interest in keeping their mouth healthy. This study evaluates oral hygiene, periodontal status, and the need for oral care and medical personnel to assist in achieving it in patients hospitalized with GC. This study was carried out on 25 patients with a diagnosis of GC, divided into two groups (GP—14 patients from the Gastroenterology Department, and SP—11 patients from the 1st Department of Surgery). Patients were examined on the day of admission (T0), the day of the medical procedure of endoscopy or surgery (T1), and the day of discharge (T2), recording the number of absent teeth, dental plaque (PI), bleeding on probing (BOP), probing depths (PPD), frequency of toothbrushing, and if the oral hygiene had been self-performed or assisted. Data were subjected to statistical analysis. Our results showed that, in both the GP and the SP group, there were strong and statistically significant correlations between PI and BOP measured on the last day of hospitalization and the period of hospitalization after the medical procedure. Longer hospital stays and the presence of surgery were risk factors for changing toothbrushing frequency. Results also highlight the need for a dentist to diagnose and eventually treat periodontal disease before and after hospitalization, and for a trained nurse who should help take care of the patient’s oral hygiene during hospitalization.

Background: Medication-related osteonecrosis of the jaw (MRONJ) may be a severe side effect of bone-modifying agents. Objective: Pathologic fractures treatment in patients with MRONJ remains challenging. The authors reported a unique case of successful non-surgical management of a mandible fracture secondary to MRONJ. Methods: A 78-year-old osteoporotic woman with a 4-year history of oral bisphosphonate therapy and a compromised dental condition developed an MRONJ-related right mandibular body fracture. Treatment consisted of systemic antibiotic administration (amoxiclav and metronidazole) and chlorhexidine mouthwash. Results: Follow-up visits revealed progressive healing of the mandibular fracture with bone callus formation and complete recovery of the ipsilateral lip and chin sensitivity after one year. Conclusion: Non-surgical management of pathological fractures related to MRONJ might be of interest in patients that refuse any type of surgery, but preventive measures, such as careful dental examination, should be taken before start antiresorptive therapy and during the treatment. The authors reported the first case in the literature of successful management of a mandibular fracture secondary to MRONJ with only antibiotics and mouthwashes.

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. 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). 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. L-PRF and A-PRF represent a valid alternative to the traditional hemostatics, reducing post-surgical bleeding and promoting wound healing. 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.

This study aimed to retrospectively evaluate the incidence of oral non-Hodgkin lymphoma (NHL) in patients referred to the Academic Hospital of the Magna Graecia University of Catanzaro from 2002 to 2020. A retrospective single-center study was performed. Patients with a histologically confirmed diagnosis of oral NHL were included. Demographic data and clinical parameters were digitally recorded, focusing on the NHL-specific localization and symptomatology. The study sample was evaluated by analyzing descriptive statistics with absolute and relative frequencies. A total of 26 patients with intraoral NHL were identified with a progressive increase in NHL occurrence during the observation period. Clinical manifestations included swelling/mass (80.7%), eventually associated with pain and ulcerations. The most common localizations were in soft tissues: buccal mucosa (38.4%), tongue (19.2%), gingiva (11.5%), cheek (11.5%). Oral NHL is rare. Clinical manifestations were unspecific, so a misdiagnosis could occur. The extranodal B-cell form of oral NHL, particularly diffuse large B-cell lymphoma, was the most common frequent oral NHL in this southern Italian population, with a progressively increased occurrence in almost 20 years.

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.

The goal of this research is to assess the desensitizing effect of a diode laser on non-carious cervical lesions (NCCLs) responsible for dentin hypersensitivity (DH) in two separate output forces implemented both independently and in sequential combination modalities. A randomized controlled trial for this study was applied. Sixty-nine NCCLs responsible for DH pain with severity between 6 and 9 on the VAS scale were considered. Three study groups were developed using just one lesion from three different quadrants of the oral cavity of each patient. All treatment procedures were conducted using a laser diode (810 nm, 5 W) with varying power outputs used separately or in combination. The pain by DH was evaluated at baseline, at treatment completion, and at 15 days and 3 months after each laser procedure. Data analysis was performed using a Wilcoxon test for paired samples, a one-way ANOVA test, and an unpaired t-test. The significant reduction of the mean VAS score was estimated in each study group immediately and at 15 days and 3 months after the end of treatment and compared with the baseline mean VAS score (p-value &lt, 0.0001). The best result concerning the improvement of DH symptomatology was assessed when a combined protocol of two different output powers of the diode laser was used. The authors conclude that the diode laser (810 nm) therapy procedure combining two separate output forces (low and high power) can improve the painful symptoms of DH from NCCLs.

Medication-related osteonecrosis of the jaw (MRONJ) is a well-recognized complication of drug therapies for bone metabolic disorders or cancer related to administration of antiresorptive (bisphosphonates and denosumab) and antiangiogenic drugs. This report describes an advanced and unusual case of stage III peri-implantitis-induced MRONJ involving the right upper jaw which was attempting to self-exfoliate. A 61-year-old male patient, rehabilitated with the placement of two implants when he was still healthy, was suffering from metastatic renal cancer previously treated with bevacizumab, interleukin-2, zoledronic acid, denosumab, cabozantinib and nivolumab. He had been under treatment of nonsurgical therapy over a year, based on antibiotic and antiseptic mouth rinse, without improvement of oral conditions. Surgical treatment consisted of massive sequestrectomy and complete surgical debridement of necrotic bone tissues. The specimen was sent for histopathologic analysis, which confirmed bone tissue necrosis with no evidence of metastatic disease. Two-month follow-up revealed a considerable life quality improvement. Although this complication is well known, the uniqueness of this case is given by its severity, related to the administration of multiple antiresorptive and antiangiogenic drugs, by the natural response of the oral cavity with the almost complete self-exfoliation of the massive necrotic zone. This case is emblematic in highlighting the controversies in the management of MRONJ, which certainly require effective collaboration of the multidisciplinary health care team that could improve patient safety and reduce the risk of developing MRONJ.

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.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.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.Current treatment options for OLP are limited. The study proved benefits of PRF injections in management of painful lesions of OLP comparable with TA.

The COVID‐19, which appeared to originate in China in December 2019, has spread worldwide pandemically. In this commentary, authors described this new challenge for dental education using the recent literature and experience gained in the Italian University of Catanzaro.

Interleukin-6 (IL-6) is a potent inflammatory cytokine that appears to play a key role in cancer growth and metastasis. In the present study, the effects of IL-6 receptor (IL-6R) on breast cancer aggressiveness and bone metastases were investigated.MDA-MB-231 (MDA-231) cells were treated in the presence or absence of anti-human IL-6 receptor (IL-6R) monoclonal antibody and examined with respect to cell survival. The expressions of signal transducer and activator of transcription 3 (Stat3), vascular endothelial growth factor (VEGF), and receptor activator of NF-κB (RANK) were analyzed by SDS-PAGE and immunoblotting. MDA-231 cells were injected into the left ventricle of mice, and then anti-human IL-6R monoclonal antibody or saline was administered intraperitoneally for 28 days. After 28 days, the incidence of bone metastases was evaluated in the hind limbs by radiography and histology.Anti-human IL-6R monoclonal antibody reduced bone metastases in an animal model injected with MDA-231 cells on radiological and histomorphometric analyses. The mechanism of bone metastasis inhibition involved inhibited cell proliferation and decreased expressions of phospho-Stat3, VEGF, and RANK in MDA-231 cells.The results of the present study suggest that inhibition of IL-6 signaling may become a preventive therapeutic option for breast cancer and bone metastases.

Background: This study aims to analyze bone compaction and osseodensification techniques and to investigate how cancellous bone compaction could influence primary implant stability (PS). Methods: Two different surgical protocols (bone compactors&mdash, BC, osseodensification drills&mdash, OD) were compared by placing 20 implants into 20 fresh pig ribs for each procedure. Peak insertion torque (PIT) and peak removal torque (PRT) were investigated using an MGT-12 digital torque gauge, and implant stability quotient (ISQ) was analyzed using an Osstell&reg, Beacon device. Results: Analysis of our data (T-test p &lt, 0.05) evidenced no statistically significant difference between BC and OD in terms of PIT (p = 0.33) or ISQ (p = 0.97). The comparison of PRT values showed a statistically significant difference between BC and OD protocols (p = 0.009). Conclusions: Cancellous bone compaction seems to improve PS, preserving a significant amount of bone and evenly spreading trabeculae on the entire implant site. Although the PIT and ISQ values obtained are similar, the PRT values suggest a better biological response from the surrounding bone tissue. Nevertheless, a larger sample and further in vivo studies are necessary to validate the usefulness of this protocol in several clinical settings.

COVID-19, which appeared to originate in China in December 2019, has spread worldwide in a pandemic way. The aim of this work is to present a protocol to standardize the outpatient oral surgery activities through remote triage, diagnostic tests, protections, and precautions that allow to provide care while minimizing risk for both patients and surgeons. This article summarizes the clinical and surgical experience of the Oral Surgery Unit of the “Mater Domini” Hospital (Magna Graecia University of Catanzaro, Italy) during the COVID-19 pandemic. The application of a scrupulous triage protocol, the use of remote consultations to limit patients’ access to the clinic, and the correct use of PPE prevented transmission of the virus between patients and staff members.

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.

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.

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 &lt, 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 &lt, 0.05). A lower GA showed a reduced retromolar space with more complex impacted M3M (p &lt, 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.

COVID‐19, which appeared to originate in China in December 2019, has spread worldwide pandemically. Recently, a letter regarding COVID‐19 impact on dentistry has been published in this Journal (Prati et al. 2020). In Europe, Italy is the second most affected nation by COVID‐19 infection and the first for number of deaths (WHO SR). In March 2020, the Italian Ministry of Health ordered the suspension of all non‐urgent outpatient activities (including dentistry) in hospitals and clinics of the public health system, until the end of the lockdown (Press releases Italian Ministry of Health, 1).

Medication-related osteonecrosis of the jaws (MRONJ) is an infectious complication of antiresorptive or antiangiogenic drug therapies. In severe stages of this disease cutaneous sinus tracts may be observed. Platelet-rich fibrin (PRF) is a second-generation platelet concentrate used in medicine and dentistry for to promote tissue healing. This report describes the management of facial cutaneous sinus tracts secondary to MRONJ with autologous PRF injections. Eight patients with the diagnosis MRONJ and facial sinus tracts were enrolled in this study and received treatment. MRONJ lesions underwent pharmacological and surgical treatment. Sinus tracts received 1-mL injections of PRF around the fistula using an insulin syringe once a week for four times starting from the day of the surgical treatment. After 4 weeks, six patients showed healing of the fistula and bone lesions, only one patient showed healing of the fistula, and no remission was reported in another one. All patients reported an improvement of the symptoms in the first 2 days after the treatment session. Patients were also satisfied from an aesthetic point of view. Further studies will be needed to determine if PRF is a valid therapeutic option in dermatology.

The aim of this systematic review was to answer the question: Is the application of autologous platelet concentrates (APCs) effective in the prevention and treatment of medication-related osteonecrosis of the jaw (MRONJ)? A literature search of PubMed, Scopus, and Web of Science databases (articles published until June 30, 2019) was conducted, in accordance with the PRISMA statement, using search terms related to “platelet concentrate” and “osteonecrosis”. The Jadad scale was used to assess the quality of the articles. Fisher's exact test was used to evaluate eventual differences between groups. Of 594 articles, 43 were included in the review (8 for MRONJ prevention and 35 for MRONJ treatment). Out of a total of 1219 dental extractions recorded (786 with APCs), only 12 cases of MRONJ have been reported (1%), all in patients with a history of high-dose antiresorptive treatment, and regardless of the use of APCs (p = 0.7634). Regarding MRONJ treatment, there were no statistically significant differences in terms of improvement between APC application and surgical treatment alone (p = 0.0788). Results are not sufficient to establish the effectiveness of APCs in the prevention and treatment of MRONJ. Randomized controlled trials with large sample size are needed.

To compare the outcome of tooth extractions in patients taking oral antithrombotic without reducing their dose. Four different interventions were compared within the same patient: suturing alone (control group), suturing plus a haemostatic plug, suturing plus advanced-platelet-rich fibrin (A-PRF+) plug, and suturing plus leukocyte- and platelet-rich fibrin (L-PRF) plug into the socket.Forty patients, taking oral antiplatelet agents, requiring the extraction of at least four non-adjacent teeth were selected for the study. After extractions the sockets were randomly allocated to suturing alone (control group), suturing plus haemostatic plug (HAEM), suturing plus advanced-platelet-rich fibrin (A-PRF+) plug, and suturing plus leukocyte- and platelet-rich fibrin (L-PRF) plug into the socket without reducing the dose of oral antiplatelets according to a split-mouth design. Outcome measures were complications, time to complete each procedure, postoperative bleeding, costs of the materials, patient preference and a wound healing index recorded 1 and 2 weeks postextraction by blinded assessors.Two weeks after extraction no patient dropped out and no complication was reported. The average time to complete suturing after tooth extractions was: 1.0 ± 0.00 minutes at control sites, 1.5 ± 0.41 at HAEM sites, 2.8 ± 0.61 at A-PRF+ sites, and 2.8 ± 0.56 at L-PRF sites, the difference being statistically significant between each pairwise comparison except A-PRF+ vs L-PRF. Postoperative bleeding 30 minutes after extractions was present at 8, 5, 1 and 2 sites for control, HAEM, A-PRF+ and L-PRF sites, respectively. A-PRF showed statistically significantly less bleeding compared to the control group (odds ratio = 0.1 (95% CI [0.01;0.86]; P0.0361). In all cases bleeding was moderate in nature and not severe. One week after extractions the mean wound healing index was 1.05 ± 0.60 for control, 1.18 ± 0.59 for HAEM, 1.00 ± 0.68 for A-PRF+ and 0.95 ± 0.50 for L-PRF sites. No statistically significant difference was detected across groups (P = 0.633). Two weeks after extractions the mean wound healing index was 0.33 ± 0.53 for control, 0.43 ± 0.50 for HAEM, 0.25 ± 0.49 for A-PRF+ and 0.15 ± 0.36 for L-PRF sites. No statistically significant difference across groups was detected (P = 0.255). One week after extractions, nine patients preferred control sites, eight HAEM, ten A-PRF+, four L-PRF and nine had no preference. No statistically significant differences were detected for control sites (P = 0.6779), HAEM (P = 1.0000), A-PRF+ (P = 0.4055) and L-PRF (P = 0.1472). Two weeks after extractions five patients preferred control sites, three HAEM, eight A-PRF+, eight L-PRF and 16 had no preference. No statistically significant differences were detected for control sites (P = 0.8147), HAEM (P = 0.2363), A-PRF+ (P = 0.3488) and L-PRF (P = 0.3488). Costs without counting sutures and blood centrifuges were 0.00, 14.49, 2.44 and 2.44 Euro for control, HAEM, A-PRF+ and L-PRF sites, respectively.It may not be necessary to discontinue the use of oral antiplatelets in patients undergoing dental extractions and, when present, the minor statistically significant differences between procedures were not clinically relevant; therefore clinicians can use any of the tested interventions according to their preference, keeping in mind that simple suturing is sufficient and is faster and cheaper, and that A-PRF+ was associated with less postoperative bleeding when compared to suturing alone.

Angioleiomyoma (AL) is an uncommon benign soft tissue neoplasia arising from the tunica media of the smooth muscle cells. AL appears as a solitary and slow-growing mass and seldom is observed in oral tissues. We reported a rare case of AL involving the cheek of a 17-year-old young woman. A review of the English-language literature was performed entering the keywords “angioleiomyoma” and “oral” in the search fields of PubMed. 70 results were identified. Excluded were cases that were not in the oral cavity or not compatible with the AL diagnosis or report lacking immunohistochemical analysis. According to the exclusion criteria, we selected 30 studies that included 63 cases of AL. The results of the review showed an average age of 42.97 years with a prevalence between the fourth and fifth decade of life with a male-to-female ratio of 1.95 : 1. The most affected sites were palate, buccal mucosa of the cheek, lip, tongue, and gingiva. Surgical excision was the treatment of choice, and diagnosis was possible through histopathological and immunohistochemical analysis. SMA, vimentin, CD34, desmin, and S-100 were the most common markers to guide the histopathological diagnosis of oral AL. In conclusion, oral AL is a rare entity, especially in adolescence as in the reported case of AL of the cheek in a 17-year-old woman. The clinical aspects of AL did not allow clinicians to make a correct presumptive diagnosis. A scrupulous histopathological analysis and immunohistochemical examinations are fundamental to differentiate AL from other lesions.
