Abstract
BACKGROUND Bisphosphonates (BPs) contrast the bone fragility and improve bone density in some metastatic cancers and bone diseases, such as Osteogenesis Imperfecta (OI). BPs use has been associated with osteonecrosis of the jaws (BRONJs) in adults needing for invasive dental procedures. AIM To conduct a systematic review on BRONJ occurrence after dental surgery in paediatric population under BPs therapy for OI, so as to identify the pre-surgical protocols adopted. DESIGN According to PRISMA guidelines, Pubmed, Web of Science (WoS) and Cochrane were investigated on September 2018, and re-checked on July 2019. Inclusion criteria were English-language papers on children/young adults (until 24 years old) reporting dental/oral surgery procedures. RESULTS Totally, 60 articles were found. After title/abstract reviews and duplicates exclusion, 22 eligible titles underwent full-text evaluation. Finally, 10 studies were included. CONCLUSIONS The lack of BRONJ occurrence in paediatric population suffering OI and treated with BPs, was confirmed, but the reasons are still debated, being the BPs therapies and the surgical strategies various and not standardized. Longitudinal studies should evaluate what happens to those former children once adult, to evaluate the delayed BRONJs onset associated with the occurrence of comorbidities during the adulthood.

Abstract
In vivo Reflectance Confocal Microscopy (RCM) allows to optically biopsy vital tissues, non-invasively and in real time. It results in horizontal virtual slices at a microscopic resolution and correlating with conventional histopathology. The aim of the present work is to describe RCM cellular and architectural findings in oral mucosae affected by erosive-ulcerative diseases, thus highlighting in vivo the wellknown histological peculiarities. A series of conventionally diagnosed Recurrent Aphthous stomatitis (RAS) and Pemphigus Vulgaris (PV) erosive and/or ulcerative oral lesions underwent RCM imaging to establish the application of RCM imaging to this kind of inflammatory non-tumoral lesions. A total of 12 RAS-related lesions and 8 PV-related lesions were considered. RCM imaging was capable to visualize their microscopic peculiarities, mainly inflammatory infiltrate, vessel dilation (RAS) and acantholytic cells, intraepithelial clefts and inflammatory cell carpets (PV). Despite RCM may result unnecessary to diagnose oral lesions referred to RAS and PV, its capability to highlight their main microscopic features could be advantageously used to monitor the healing or worsening of the clinical situation as well as the responsiveness/refractoriness to therapy.

Abstract
Candida species are commensal yeasts of the oral cavity, which, under predisposing systemic and/or local circumstances, are responsible for a wide variety of clinical manifestations, globally known as oral candidiasis. Candida-associated denture stomatitis is an oral candidiasis particularly affecting the oral mucosa covered by a dental prosthesis, with several degree of severity. Diabetics suffer oral candidiasis more frequently than healthy individuals do and if they are denture wearers, the risk increases. Since various controversies still remain regarding the interrelationship among diabetes, oral Candida spp. strains involved in denture stomatitis and the presence of dentures, the present review aims to investigate the differences in Candida species frequencies and degree of denture stomatitis severity existing among diabetic and non- diabetic individuals, with and without dentures.

Abstract
Oral mucosa pigmentations belong to a heterogeneous variety of lesions, which are usually divided into two groups: exogenous or endogenous pigmentations. The pigmented lesions most frequently found in the oral mucosa are the amalgam tattoo, the melanotic macula and the nevus. All these lesions may affect every part of the oral mucosa, and they may represent a hard diagnostic challenge for the clinician; the clinical objective examination is not sufficient to make a correct diagnosis. Reflectance Confocal Microscopy provides a real-time microscopic evaluation of tissue layers, and is widely considered a useful auxiliary tool in monitoring skin and mucosa lesions. In this context, Reflectance Confocal Microscopy imaging is a valid aid in the management of oral mucosa pigmented lesions, to corroborate and support the diagnostic process.

Abstract
Photodynamic Therapy (PDT) is a minimally invasive approach that has shown promising results in management of oral, head and neck lesions. PDT can be used alone or in combination with other conventional treatments (surgery, chemotherapy, radiotherapy). Oral Lichen Planus (OLP) is a mucosal and cutaneous chronic disease characterized by an autoimmune insult of basal keratinocytes. We aim to evaluate the feasibility of topical toluidine blue-mediated PDT for the treatment of oral cavity multifocal homogeneous white lesions by oral lichen planus without dysplastic features.

Abstract
The possibility of the non-parenteral Hepatitis C Virus (HCV) transmission is supported by the demonstration that the actual virus is present in several body fluids, including saliva. From a review of the literature many investigators have found the presence of HCV-RNA in saliva, however, widely contrasting results emerge, with detection rates ranging from 0–100%. To further examine HCV salivary shedding, saliva samples were collected from 46 chronically HCV-infected patients and tested for HCV-RNA and occult blood. Quantification and genotyping of serum HCV-RNA were also carried out for each patient. HCV-RNA was detected in 39.13% of the saliva samples. The viral salivary shedding was significantly related to viraemia levels, serum viral genotype and the presence of salivary occult blood. Our findings indicate that the HCV salivary shedding occurs in about one third of HCV-infected patients, but seem to suggest that it is unlikely when the serum viral genotype is 3a. Moreover, blood leakage into the oral cavity is possibly the main source of the salivary HCV-RNA. Although the occurrence of the viral salivary shedding does not necessarily mean that HCV trasmission occurs by saliva, our results suggest the need for further investigations into the biological factors possibly involved in HCV mucosal transmission related to both the source and the exposed subjects.

Abstract
YouTube is increasingly being used by patients to obtain health-related information. No studies have evaluated the content of YouTube videos on children oral thrush. The aim of this work is to examine the quality of information offered by this platform about oral thrush in children. Searching term oral thrush in children (OTC) displayed a total of 2.790 results. Of the top 60 videos analyzed, 27 were excluded. The main source of upload was from generalist information YouTube® channels (GC) followed by healthcare professionals (HP), individual users (IU), and healthcare information channels (HC); usefulness of videos is successfully correlated with the number of visualization, number of likes and viewing rate and was interdependent with the number of visualizations, number of likes and VR. However, videos on the oral thrush do not have satisfactory quality information. HP themselves, along with HC, do not seem to provide more appropriate information on COT, than GC or IU.

Abstract
The aim of this study was to evaluate the prevalence of psychiatric symptoms in patients with oral lichen planus (OLP) compared to a control group. Eleven patients (mean age 65.2 years-old), with diagnosis of OLP and 13 controls (mean age 64.8 years-old) underwent a psychiatric evaluation with five psychometric scales: Visual Analogue Scale (VAS), Hamilton Rating Scale for Depression (HAM-D), State-Trait Anxiety Inventory (STAI 1-2), Distress Thermometer (DT) and Brief Fatigue Inventory (BFI). Seventy-three % of OLP group presented a VAS score of mild type; 9% had depressive symptoms; 100% of the sample had a score above the cut-off for state and trait anxiety; 45% presented Distress (36% moderate type). However, no statistical difference was found in comparison with the control group. In this study, there was no difference in these parameters between the OLP group and the control group. Perhaps, a larger cohort of patients could give different results.

Abstract
Photodynamic Therapy (PDT) is a minimally invasive treatment that has shown promising results in treating preneoplasticlesions. PDT reckons on the administration of a drug (photosensitizer), which can be used in a topical or systemic form. Photodynamic therapy has been successfully used in the management of a variety of pathologies from different anatomical sites, including the head, neck, brain and lungs, hepatobiliary tree and other gastrointestinal and urological pathologies, skin, gynaecological conditions and in vascular anomalies. Starting from these same considerations, PDT has also been adopted for oral malignant and premalignant lesions treatment, and should be kept under investigation as a promising therapeutic management of leukoplakia and preneoplastic lesions of the oral cavity.

Abstract
Patients affected by Prader-Willi Syndrome (PWS) usually show orofacial dysfunction, poor oral hygiene, severe tooth wear, generalized caries and thick sticky saliva. The aim of this study was to evaluate molecular/ionic changings in PWS patients compared to controls, as well as unstimulated salivary flow rate (SFR); 7 patients with a mean age of 20.0±5.45 years were enrolled in the study group (PWS group) and 5 patients with a mean age of 22.6±3.05 years, in the control group. Results showed a greater Na+ (p=0.003), Cl+ (p=0.004) and P (p=0.001) concentration in saliva of PWS group as well as a greater concentration of secretory IgA (p=0.003) with a reduction of SFR (p=0.004) compared to controls. A Spearmans analysis (based on the SFR of both groups) revealed an inverse correlation with Na (rho=-0.747), Cl (rho=-0.723), P (rho=-0.637) and sIgA (rho=-0.707) concentration and SFR, when linear regression model was performed only P and SFR were interdependent (ß=-0.748; p=0.005).

Abstract
Recurrent aphthous stomatitis (RAS) is one of the most common causes of mouth sores in children so the management of this condition is a matter of great importance. YouTube is increasingly being used by patients to obtain health-related information. The aim of this work is to examine the quality of information offered by YouTube about mouth sores in children (MSC). Searching the term mouth sores in children, (MSC) displayed 12.300 results. Of the top 60 videos analyzed, 31 were excluded following exclusion criteria. The major source of upload was from healthcare information channels (HC-41,38%), followed by individual users (HP-25.59%), healthcare professionals (IU-17.24%) and generalist information channels (HC-13.78%); 20.69% of them deal with predisposing factors, and related pathologies, the majority of these propose home remedies (60.72%) rather than topical analgesic drugs (21.43%), antimicrobials (7.14%) and topical steroids (3.57). Most of the videos analyzed were slightly useful (68.97%). Information about mouth sores in children on YouTube was poor regardless of the upload source. Analyzing health content on social platforms is a starting point for providing greater quality of health-related information.

Abstract
Orofaciodigital syndrome (OFD) is a group of hereditary disorders identified by malformations of the mouth (oris), face (facies), hands and feet (digitus=finger and toe). Although there are several different types reported in the literature, there is a great overlap in their clinical presentation. The full spectrum of all disorders due to OFD is not yet fully understood, since each patient shows variations in the expression of the syndrome. In the oral cavity, teeth are often affected by various alterations, such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis. Treatment of a syndromic patient with a complex picture showing conditions such as palatine fissures and a severe hypodontia involves a multidisciplinary approach and a careful periodical follow-up.

Abstract
Orofaciodigital syndromes (OFD) are rare genetical disorders characterized by malformations of the mouth (oris), face (facies), hands and feet (digitus = finger, toe). It is still impossible to fully understand the whole spectrum of all dysfunctions due to OFD, since the expressions of the syndrome vary in each patient. There are various alterations, thoroughly described in literature that can affect the oral cavity such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis. A syndromic patient with a complex picture showing conditions such as palatine fissures and a severe hypodontia has to be treated using a multidisciplinary approach, and in particular, needs a prosthetic rehabilitation for the restoration of missing dental elements in the arch.

Abstract
Stem cells play a role in many mucosal disorders characterised by abnormal proliferation and differentiation of keratinocytes, such as oral lichen planus (OLP). In OLP there were changes in stem cell markers as component of integrin complexes α6 and β1 integrin increased along with increase of melanoma-associated chondroitin sulphate proteoglycan (MCSP) and decreased of notch1 (N1) and keratin 15 (K15). Stem cell marker expression may be altered by pathological signalling in these lesions. Cadherins are transmembrane receptors that provide cell-cell contact and communication function through calcium-dependent homophilic and heterophilic interactions. In actively diseased areas of OLP lesions, basal keratinocytes downregulate CD40 and were focally E-cadherin-negative, in contrast to non-diseased areas and normal oral mucosa. This loss of E-cadherin expression may contribute to epithelial basal cell destruction and T-cell migration into the epithelial compartment in OLP. In addition, Growth factor pathways as a role in OLP and has been analyzed in this review.

Abstract
To compare the results of psychometric tests in patients with BMS and controls, participants were tested for depression, anxiety, fatigue and distress. Patients with BMS had noticeably higher scores for depression, fatigue and distress, compared to controls. Depression and distress were significantly correlated with the burning symptom. Moreover, distress and burning symptoms proved to be interdependent. Depression seems to play a specific role in BMS. Burning symptoms affect quality of life of patients and they could be a predictor of distress.

Abstract
Oral mucosa is constantly under the influence of various internal and external stimuli, therefore it is interested by a range of developmental disorders, irritation, inflammation, and neoplastic conditions. Traumatic fibroma is one of these lesions. The aim of this work is to obtain an ultrasound characterization of a lip fibroma with a high frequency probe (8-18 MHz) as feasibility and experimental model of this non-invasive technique in the oral mucosa compared with its histo-pathological section. Ultrasound characterization of a fibroma in a 50-year-old patient in the right retro commissural area of mucosa was performed. The ultrasound images were compared with its histological image. Fibroma is a traumatic lesion clinically recognizable and with a complex and well-defined histopathology structure. Although further investigations are necessary to determine the potential of ultrasonographic images as an aid in the diagnosis of oral lesions, this case report might be a model for ultrasound imaging compared with its histological section.

Abstract
This preliminary study aims to establish the Virtual Chromoendoscopic Magnification (VCM) feasibility to visualize and distinguish the Intraepithelial Papillary Capillary Loops (IPCL) patterns of benign oral pathologies from malignant ones. Thirty-one consecutive subjects affected by oral lesions/pathologies underwent white light examination and VCM imaging by the Narrow Band Imaging System (Olympus Medical Systems Corp., Tokyo, Japan). A class system of four IPCL types corresponding to progressive vessel disarray was adopted. IPCL type IV were considered criterion of malignancy. A histopathological exam completed the diagnosis: sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated. IPCL patterns of benign oral entities ranged from types I to III. IPCL type IV was associated with malignancy in 4 out of 6 cases. Sensitivity, specificity, PPV, and NPV were 100%, 93%, 67% and 100%, respectively. This study preliminarily describes IPCL patterns of different oral mucosal diseases and confirms the association between IPCL IV and oral cancer.

Abstract
PURPOSE To identify potential antigenic targets for Porphyromonas gingivalis vaccine development. MATERIALS AND METHODS In the present study, we analyzed the Porphyromonas gingivalis, fimA type II primary amino acid sequence and characterized the similarity to the human proteome at the pentapeptide level. RESULTS We found that exact peptide-peptide profiling of the fimbrial antigen versus the human proteome shows that only 19 out of 344 fimA type II pentapeptides are uniquely owned by the bacterial protein. CONCLUSIONS The concept that protein immunogenicity is allocated in rare peptide sequences and the search the Porphyromonas gingivalis fimA type II sequence for peptides unique to the bacterial protein and absent in the human host, might be used in new therapeutical approaches as a significant adjunct to current periodontal therapies.

Abstract
PURPOSE Oral Lichen Planus (OLP) is a chronic inflammatory disease of skin and mucous membranes. Approximately 20% of women with oral lichen planus develops lesions in the genital mucosa. In 1982, Pelisse described a special form of lichen planus (LP), which consists of a triad of symptoms: vulval, vaginal and gingival (VVG)-LP lesions. Aim of the present report is to report two new cases and review the international literature. MATERIAL AND METHODS Two cases of VVG-LP are reported and a review of recent literature is performed. RESULTS The onset of erosive or ulcerative mouth lesions may precede or follow by months or even years the onset of vulvovaginal lesions. Vaginal agglutination is associated with the postmenopausal state in conjunction with a dermatologic condition. Intra-lesional corticosteroids have a role in localized chronic ulceration, while systemic therapies such as corticosteroids, azathioprine, mycophenolate mofetil, hydroxychloroquine, ciclosporin, methotrexate, retinoids, thalidomide and photo chemotherapy have been used in more severe cases with varying success. CONCLUSIONS VVG-LP is rather a rare condition and has been documented in the literature mainly in the form of case reports. Lack of a precise diagnostic criteria of VVG-LP depends on the specialists.

Abstract
Discoid Lupus Erythematosus (DLE) is a chronic disease with a typical cutaneous involvement. This pathology rarely involves mucosa: oral cavity is interested in 20% of DLE patients. We describe a case of oral DLE in a 50-year-old woman with an anamnesis for autoimmune disorders. This study shows the helpful role of immunofluorescence in the diagnosis of autoimmune diseases. The first diagnostic step was the clinical observation of the oral mucosa: the lesion area was erythematous, athrophic and hyperkeratotic. The patient then underwent laboratory examination. We utilized human epithelial cells (Hep-2010) for Indirect Immuno-Fluorescence (IIF). Moreover, the biopsy site for Direct Immuno-Fluorescence (DIF) and histopathological analysis was the untreated oral lesion. IIF detected an increase of Anti-Nuclear Antibody (ANA) and positivity for SSA-RO. By DIF, we observed IgG/IgA/fibrinogen along basal layer. Multiple biopsies reported signs of chronic basal damage. Steroid systemic therapy induced a considerable lesion regression. We suggest the use of immunofluorescence with the integration of further data to improve diagnosis of rare diseases and to establish a suitable therapy.

Abstract
OSCC is the most frequent malignant tumour of the oral cavity, accounting for more than 90% of malignant tumours of this anatomic region and it often arises from precursor lesions. Aside from tobacco and alcohol consumption, further determinants have been considered to increase the risk of OSCC development, such as micronutrient deficiencies, chronic traumatism, poor oral hygiene and viruses. Recurrence, survival and conversely, mortality depends on numerous and different biological, histological, macroscopic and microscopic factors that have been investigated in order to define causes, to help diagnosis and to refine appropriate treatments that perfectly fit with the different features of OSCCs. For this purpose, during the last decades, the improvement of scientific technologies and molecular analyses have allowed to investigate markers and genetic and epigenetic factors, in order to clarify their responsibilities related to early diagnosis and OSCC progression and prognosis in order to address them as targets in future selective and individually-shaped therapies. This review will focus on the etiology, advances in diagnostic markers and prognostic indicators for oral cancers.

Abstract
To compare the performance, by scanning electron microscopic analysis, of the interface between tooth and four commercial restorative composite resins in Class I cavities following exposure to acidified artificial solution, pH 4.5, with a background electrolyte composition similar to saliva, 600 teeth were divided into 4 groups. The first group was treated with microfilled light-cured Heliomolar; the second group with Durafill; the third group with the microfilled self-cured Isomolar; and the fourth group was treated using the hybrid self-cured Miradapt. All teeth of each group were randomly divided into two sub-groups: A) a control group that was immersed in artificial saliva (pH 7); B) a study group that was immersed in artificial saliva acidified with phosphoric acid (pH 4.5) in order to obtain artificial caries. The samples were examined by scanning electron microscopy. Data were analyzed using Pearsons Chi-squared test (χ2) with R statistical software. The statistical analyses demonstrated significant differences in the two sub-groups A and B when considered for the light-cured composites whereas no difference was monitored for self-cured composites. Statistical analysis (p minore di 0.001) also demonstrated that the type of composite strongly influenced the infiltration grade. Our results demonstrate that incremental layering techniques might improve the marginal adaptation for light-cured composites, while self-cured show a marked polymerization contraction which can cause marginal breakdown.

Abstract
Pemphigus vulgaris (PV) is an autoimmune disease that manifests as intraepithelial blisters in skin and mucous membranes. We report the case of a 62-year-old female patient with clinical picture of desquamative gingivitis and a histological and serological diagnosis of pemphigus vulgaris. The aim of this study is to analyse bollous oral diseases in order to evaluate the feasibility to image epithelial architecture of oral mucosae using in vivo optical coherence tomography. Optical coherence tomography seems to be a valid non-invasive auxiliary diagnostic device able to show in vivo the epithelial layers and basal membrane.

Abstract
BACKGROUND The prognosis of the oral squamous cell carcinoma (OSCC) patients remains very poor, mainly due to their high propensity to invade and metastasize. E-cadherin reduced expression occurs in the primary step of oral tumour progression and gene methylation is a mode by which the expression of this protein is regulated in cancers. In this perspective, we investigated E-cadherin gene (CDH1) promoter methylation status in OSCC and its correlation with Ecadherin protein expression, clinicopathological characteristics and patient outcome. METHODS Histologically proven OSCC and paired normal mucosa were analyzed for CDH1 promoter methylation status and E-cadherin protein expression by methylation-specific polymerase chain reaction and immunohistochemistry. Colocalization of E-cadherin with epidermal growth factor (EGF) receptor (EGFR) was evidenced by confocal microscopy and by immunoprecipitation analyses. RESULTS This study indicated E-cadherin protein down-regulation in OSCC associated with protein delocalization from membrane to cytoplasm. Low E-cadherin expression correlated to aggressive, poorly differentiated, high grade carcinomas and low patient survival. Moreover, protein down-regulation appeared to be due to E-cadherin mRNA downregulation and CDH1 promoter hypermethylation. In an in vitro model of OSCC the treatment with EGF caused internalization and co-localization of E-cadherin with EGFR and the addition of demethylating agents increased E-cadherin expression. CONCLUSION Low E-Cadherin expression is a negative prognostic factor of OSCC and is likely due to the hypermethylation of CDH1 promoter. The delocalization of E-cadherin from membrane to cytoplasm could be also due to the increased expression of EGFR in OSCC and the consequent increase of E-cadherin co-internalization with EGFR.

Abstract
Some species of Candida are opportunistic pathogens that can cause disease in a host immunocompromised by underlying local or systemic pathological processes. C. albicans is the species most often associated with oral lesions, but other species of Candida, including C. glabrata, C. tropicalis and C. parapsilosis, have also been isolated in the saliva of subjects with and without candidiasis. In the present study we evaluated the host defence mechanisms induced by Candida albicans and other Candida species in monocytes and oral epithelial cells in order to establish the existence of a species-specific cellular response. Our results indicated that, during Candida species infection, the epithelial cells actively participate in the host defence by producing antimicrobial peptides and proinflammatory cytokines. Moreover, in infections caused by Candida tropicalis and Candida glabrata, the host defence may be strengthened by the release of perforin and granzyme by polymorphonuclear leukocytes recruited at the site of infection.
