Objectives: Lichen sclerosus is a rare chronic inflammatory disorder, affecting mainly the skin and the anogenital mucosa, while oral lesions can be the primary or the only manifestation of the disease. A rare case of oral lichen sclerosus, assessed histopathologically and histochemically, is presented, along with a thorough review of the English language literature. Material and Methods: A 32-year-old female presented an asymptomatic white patch affecting the skin and the mucosa of the upper lip, without other mucocutaneous involvement...

Objectives: Oral squamous cell carcinoma is associated with alterations in basement membrane. Laminin-332 is present in basal lamina and performs multiple biologic effects by γ2 chain. Matrix metalloproteinase acts disrupting extracellular components and was related to poor prognosis in cancer. Here, molecular profile of laminin-332 γ2 chain and matrix metalloproteinase-9 was assessed in oral lesions. Material and Methods: The expression of laminin-332 γ2 chain and matrix metalloproteinase-9 (MMP-9) was examined by immunohistochemistry in 10 patients with high risk of malignant transformation oral lesions and 26 cases of oral squamous cell carcinoma (OSCC)...

Objectives: The aim of this study was to assess the interaction of a bioactive glass scaffold with cells derived from dental pulp, dental follicle and periodontal ligament. Material and Methods: Impacted third molars were surgically removed from three young donors. Cells from the dental pulp, follicle and periodontal ligament tissues were isolated and expanded. Different cell populations were characterised using specific CD markers. Expanded pulp, follicle and periodontal cells were then seeded onto bioactive glass scaffolds and cultured in osteogenic medium or basic medium...

Objectives: The purpose of the present study is to systematically review the accuracy of implant placement with mucosa-supported stereolithographic surgical guide and to find out what factors can influence the accuracy. Material and Methods: An electronic literature search was performed through the MEDLINE (PubMed) and EMBASE databases. The articles are including human studies published in English from October 2008 to October, 2017. From the examination of selected articles, deviations between virtual planning and actual implant placement were analysed regarding the global apical, global coronal, and angulation position...

Background: Avulsion of the permanent teeth is one of the most serious oral health problems among active children and adolescents. Traumatized patients require immediate and correct treatment in order to restore damaged structures and function that have major impact on daily patient's life. As a result, proper guidelines and fast treatment methods are necessary. This case report discusses treatment of maxillary right central incisor with an open apex that had been avulsed and replanted...

Objectives: The present paper reports data of a randomized study aimed to analyse and compare the histologic and histomorphometric aspects of bone healing in extraction sites covered with collagen membrane alone or associated with porcine-derived bone graft. Material and Methods: Thirty patients, with single extraction sockets without severe bone wall defects in the premolar/molar region, were included. Ten extraction sockets were grafted with porcine-derived bone and covered with collagen membrane (group 1), 10 sites were covered with collagen membrane alone (group 2), and 10 sites healed spontaneously (group 3)...

Objectives: Sialorrhea is a common health and psychosocial problem for children with neuromuscular dysfunction secondary to a variety of disorders such as cerebral palsy. Current accepted treatments include the injection of botulinum toxin into the submandibular glands for temporary symptom relief. The purpose of this study is to demonstrate the feasibility of percutaneous ethanol injection for longer lasting salivary gland ablation in an animal model. Material and Methods: Twenty rats were used in this study...

Objectives: There aren't any objective methods that may help in standard evaluation of oral surgery patient's psycho-emotional status. Without any standardized evaluation, two main problems appear: heterogeneity between studies and ineffective patient's evaluation. Therefore, Universal Scale in Oral Surgery (USOS) for patient's psycho-emotional status rating has previously been proposed by authors. The aim of present study is to assess the clinical effectivity and validate the Universal Scale in Oral Surgery in case of outpatient tooth extraction for adult healthy patients...
