#1
Irineu Gregnanin Pedron, Alessandro Mangano
The pursuit of esthetic excellence has become a major goal in the dental treatment and orthodontic treatment. The beauty of the smile is not only constituted by the shape, position, and size of the teeth, but also based on the characteristics of the gingival tissue and conformation of the lips, which should be as harmonious as teeth. Gummy smile is one of the complaints of the patients, since such a situation can influence self-esteem and social relationships. The development of new more conservative techniques may provide a better therapeutic option than surgical procedures, such as the application of botulinum toxin, in the treatment of gummy smile...

Dens Invaginatus is a developmental disturbance resulting from abnormal morpho differentiation. It is characterized by an invagination of the enamel and dentin, creating a lumen inside the affected tooth, which may extend as deep as the apical foramen. In the present scenario, calcified Oehler's type IIIb dens invaginatus in left maxillary lateral incisor in 23-year-old male patient was seen. As the two-dimensional imaging lacks accuracy in such complicated cases, cone beam computed tomography was used to assess the calcification three dimensionally...

Solitary myofibroma is an uncommon benign soft tissue neoplasm of myofibroblastic origin exhibiting head and neck region predilection but its presence in the jaws is rare. Myofibroma presents as painless mass and may demonstrate rapid enlargement and growth that clinically mimic malignancies. This report presents a 4-year-old male patient with a rapidly growing mandibular gingival mass with some evidence of underlying alveolar bone destruction. Incisional biopsy was performed and the specimen was stained with hematoxylin and eosin and immunohistochemical antibodies for αSMA, CD34, S100 and desmin...

Immune thrombocytopenic purpura (ITP) is an immune-mediated acquired disease found in both adults and children. It is characterized by transient or persistent decreases in the platelet count. We report a case of ITP detected based on oral hemorrhagic symptoms. The patient was a 79-year-old female with no significant past medical history. She presented with sudden onset of gingival bleeding and hemorrhagic bullae on the buccal mucosa. Gingival bleeding was difficult to control. Laboratory tests revealed severe thrombocytopenia with a platelet count as low as 2000/μL...

Many studies reported them as the regulators of the growth, dissemination, and clinical behavior of various lesions. There are relatively scarce data regarding the role of macrophages in oral lesions, particularly odontogenic lesions. Purpose: This study investigated the macrophage density in odontogenic lesions of diverse biologic performance. Materials and Method: In this comparative analytical study, 60 cases of odontogenic lesions including ameloblastoma, keratocystic odontogenic tumor, dentigerous cyst, and radicular cyst were immunohistochemically stained with anti-CD68 antibody...
