Background: Currently, one of the most discouraging aspects for many patients undergoing dental procedures is the administration of local anaesthesia. Therefore, there is a constant search for new techniques to avoid the invasive and painful nature of the injection. This study aimed to compare the clinical efficacy of local anaesthetics with articaine 4% or mepivacaine 2% (both with epinephrine 1:100.000), using different anaesthetic techniques to perform germectomy of lower third molars and to assess patients' feelings and pain during surgery. Methods: Totally 50 patients (ranged 11-16 years) who required germectomy of mandibular third molars were recruited. Each patient received local anaesthesia on one side with articaine inoculated with plexus technique while on the other side with mepivacaine using inferior alveolar nerve block technique. The patients' evaluation was performed on pre and intraoperative tactile-pressure feelings and intraoperative pain with four levels on the Visual Analogue Scale (VAS). Results: Surgical operations lasted less with more efficient analgesia when articaine was used. The additional intraosseous injection was required mainly in the mepivacaine group intraoperatively. A few patients had tactile-pressure feelings while intraoperative pain sensation was absent in 90% of cases with articaine. Significant differences were found in the cases who reported "absent" and "moderate" VAS values, favoring the use of articaine. Conclusions: Articaine injected with a plexus anaesthetic technique seems to be more clinically manageable than mepivacaine for the mandibular third molar germectomy. The discomfort of tactile-pressure feelings and pain experienced was lower using articaine anaesthetic technique used.

The aim of this work was to describe a case of unicystic ameloblastoma located in the left posterior mandibular body and angle of a 14-year-old Caucasian male. The tumour was described at clinical and histological level; moreover, its histopathological phenotype was depicted. Finally, the problems of differential diagnosis with odontogenic or congenital cyst and the most appropriate therapeutic procedures are discussed.

Oral soft tissue lesions are commonly seen in the daily dental practice. The quick diagnosis of oral potentially malignant disorders and oral precancer disease is of highest clinical importance given the mortality rate of late stage disease. Since the oral cavity is more accessible to complete examination, it could be used in early detection of precancerous and cancerous lesions. But either due to ignorance or inaccessibility of medical care, the disease gets detected in the later stages. Thus, there is a need for improvement in early detection of oral disease, because in the initial stages, treatment is more effective and the morbidity is minimal. Aim of this report is to highlight how collagen membrane graft application seems to offer a perfect healing of the soft tissue after the lesion removal. Some reports and the microstructure of the collagen used have been recorded. The healing of the soft tissue, the bleeding control and the management of postoperative discomfort seem to be more favorable by avoiding a intraoral soft tissue graft and applying a collagen membrane.

The occurrence of lymphoepithelial carcinoma in the oral cavity is extremely rare and a case with involvement of minor salivary glands is very uncommon. We describe a case of LELC of the oral cavity with involvement of the upper lip and of minor salivary glands. The tumour was described at the clinical and instrumental level; moreover, its histopathological phenotype was defined. Finally, the problems of differential diagnosis and the most appropriate therapeutic approaches are discussed.
