Early diagnosis of oral squamous cell carcinoma may ensure better prognosis: A case series.

Oral squamous cell carcinoma is an extremely malignant tumour: in order to reduce mortality and morbidity, early diagnosis and treatment is the clinician's best weapon.

Mucosal Melanoma of the Hard Palate: Surgical Treatment and Reconstruction.

Mucosal melanomas of the head and neck region are uncommon pathologies that can affect the oral cavity, and are characterized by a high rate of mortality. Considering the lack of knowledge regarding risk and prognostic factors, current best clinical practice is represented by a large surgical excision with disease-free margins, eventually associated with a reconstructive flap. Indeed, given the frequent necessity of postoperative radiotherapy and fast healing process, a reconstruction of the surgical gap is advisable. Even if several flaps have been most commonly used, the submental island flap represents a valid alternative thanks to local advantages and similar oncologic outcomes compared to free flaps.

Solitary Extramedullary Plasmacytoma Presenting as Asymptomatic Palatal Erythroplakia: Report of a Case.

Solitary plasmacytoma (SP) is a rare malignant tumor of plasma cells with no systemic spread; however, when it disseminates and affects multiple skeletal sites, it is called multiple myeloma (MM). The etiology of solitary plasmacytoma is unknown, with two possible subtypes: solitary extramedullary plasmacytoma (EMP) and solitary bone plasmacytoma (SBP). We present a case of EMP arising as asymptomatic erythroplakia of the palate, which is rarely described in the literature. The definitive diagnosis was obtained with immunohistochemical studies, after which the lesion was subjected to excisional biopsy. At present, after two years of close follow-up, the patient has shown no signs of relapse or conversion to MM. The uniqueness of the case highlights the possibility of an atypical EMP lesion in the head and neck, thus posing a diagnostic and therapeutic challenge for physicians.

Oral Cancer and Precancer: A Narrative Review on the Relevance of Early Diagnosis.

Oral cancer (OC) is an uncommon malignancy in Western countries, being one of the most common cancers in some high-risk areas of the world. It is a largely preventable cancer, since most of the different risk factors identified, such as tobacco use, alcohol consumption, and betel nut chewing, are behaviors that increase the likelihood of the disease. Given its high mortality, early diagnosis is of utmost importance. Prevention and the anticipation of diagnosis begin with identification of potentially malignant lesions of the oral mucosa and with local conditions promoting chronic inflammation. Therefore, every lesion must be recognized promptly and treated adequately. The clinical recognition and evaluation of oral mucosal lesions can detect up to 99% of oral cancers/premalignancies. As stated by the World Health Organization, any suspicious lesion that does not subside within two weeks from detection and removal of local causes of irritation must be biopsied. Surgical biopsy remains the gold standard for diagnosis of oral cancer. Adjunctive tools have been developed and studied to help clinicians in the diagnostic pathway, such as toluidine blue vital staining and autofluorescence imaging. In the near future other methods, i.e., identification of salivary markers of progression may help in reducing mortality due to oral cancer.

Oral mucosal complications in orthodontic treatment.

BACKGROUND: Orthodontic therapy is used to solve numerous oral problems, but the use of fixed oral devices can also impact negatively the oral cavity, if the treatment is not steadily under control. The aim of this study is to evaluate tooth, bone and soft tissues lesions due to the presence of fixed orthodontic appliances. METHODS: One hundred patients with fixed orthodontic appliances were included in the study. In particular, 20 patients with rapid palatal expander (RPE), 20 patients with Forsus appliance, 20 patients with a fixed multibracket appliance treatment, 20 patients with just the lower vestibular multibracket treatment and 20 patients with both upper and lower vestibular multibracket treatment. An accurate oral examination of the oral cavity, comprehending teeth, bone and soft tissues, was carried out thoroughly, in order to find possible lesions caused by the fixed orthodontic treatment. RESULTS: Concerning RPE, 35% patients had reversible palatal lesions, while 45% patients had the impression of the appliance on the tongue. Periodontal damages were observed in 5% of the patients, as well as tooth lesions (i.e. dental caries). 20% of the patients with Forsus appliance experienced the lesion on the cheek mucosa, while 10% individuals reported periodontal problems, and 15% of the subject suffered for WSL (white spot lesion) and dental caries. Upper vestibular multibracket appliance caused superior labial lesions (15%), cheek mucosal lesions (20%), gingivitis (55%), white spot lesions (WSL) of superior teeth (15%), while dental recessions and periodontitis due to the appliance were rarely observed (5%). Lower vestibular multibracket appliance was frequently the cause of inferior labial lesions (15%), cheek mucosal lesions (15%), gingivitis (50%), WSL of inferior teeth (20%) and also in lower arch dental recessions and periodontitis due to the appliance were rarely observed (5%). Patients with both superior and inferior multibracket appliance experienced upper and/or lower lip lesions (25%), lesions of cheek mucosa (25%), gingivitis (65%) and WSL (30%), and just in few cases periodontitis (10%). Data shows a more critical oral situation in patients with both superior and inferior appliances than people with one-arch therapy. CONCLUSIONS: Orthodontic therapy offers a considerable number of advantages, but it is important to underline what may be the adverse consequences also. This allows the orthodontist to inform the patient of all the possible effects of their therapeutic choice. In most cases, RPE can cause an impression of the device on the tongue and reversible lesions of the palate. On the other hand, the orthodontic fixed therapy can cause gingivitis, followed by mucosal lesions, labial lesions and WSL. For these reasons, an accurate assessment of the patients before the application of fixed orthodontic treatment is necessary. Oral hygiene instructions and motivation are very important, as well as periodic controls of the fixed oral device.

Inflammatory and Oxidative Responses in Pregnancies With Obesity and Periodontal Disease.

BACKGROUND: Maternal obesity is related to immunologic and inflammatory systemic modifications that may worsen the pregnancy inflammatory status. Hormonal changes during pregnancy can adversely affect oral biofilms and oral health initiating or worsening periodontal diseases, with enhanced local and systemic oxidative stress and inflammation. OBJECTIVE: The aim of this study was to examine the relationship between local salivary and systemic parameters of oxidative stress and inflammation in relation to obesity and periodontal diseases. STUDY DESIGN: Sixty-two women with singleton pregnancies were enrolled. Twenty-seven women were normal weight (NW; 18.5< body mass index [BMI] <25 kg/m2) and 35 obese (BMI ≥30 kg/m2). Seventeen of the obese had gestational diabetes mellitus (GDM). During third trimester, periodontal status was evaluated, saliva (s) was collected to assess total antioxidant capacity (s-TAC) and C-reactive protein (s-CRP) levels, and venous plasma (p) was used to measure CRP levels (p-CRP). Maternal, fetal, and placental data were registered at delivery. RESULTS: Levels of s-TAC, s-CRP, and p-CRP were significantly higher in obese, particularly in the presence of GDM, compared to NW and related to each other ( P = .000; r > 0.59), to maternal BMI ( P = .000; r > 0.52), and fasting glycemia ( P < .002; r > 0.47). Periodontal disease was more frequent in obese groups (80%) versus NW (52%; P = .04), particularly when GDM was diagnosed ( P = .009). A significant interaction effect between maternal BMI and oral condition was found for s-TAC levels. Obese with periodontitis showed significant increase in local and systemic parameters versus NW. CONCLUSION: Obesity and periodontal disease could synergistically amplify the inflammatory and oxidative status, resulting in increased local and systemic biomarkers particularly when GDM is diagnosed.
