1/4. Multidisciplinary evaluation and clinical management of mesiodens.Supernumerary teeth are a disorder of odontogenesis relatively common in the oral cavity and characterized by an excess number of teeth. The term mesiodens is used to refer to an unerupted supernumerary tooth in the central region of the premaxilla between the two central incisors. The complications associated with mesiodens include: lack of eruption of permanent teeth, the deviation of the eruption path, rotations, retention, root re-absorption and pulp necrosis with loss of vitality, and diastema. Early detection of mesiodens is most important if such complications are to be avoided. This report describes the treatment of a maxillary central incisor impacted by a mesiodens. The case initially required only surgical treatment, to remove the supernumerary tooth. Successively, orthodontic therapy was done to bring into position the left permanent central incisor, which erupted physiologically, but rotated 90 degrees around along its long axis.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/4. Compound odontoma erupting in the mouth: 4-year follow-up of a clinical case.A case of a compound odontoma erupting in the oral cavity is presented: a follow-up study of 4 yr has been performed evaluating the possible relationship with a previous dental trauma. A discussion is presented concerning the etiologic aspects, clinical signs, diagnostic aids and therapeutic approaches to this type of lesion.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
3/4. Aberrant root formation: review of root genesis and three case reports.The mechanism of root formation and tooth eruption is a complex process which is not fully understood. Prior to a tooth emerging into the oral cavity, root genesis is initiated by derivatives of the enamel organ. The dental follicle mediates an eruption pathway allowing for movement of the developing tooth in a coronal direction. As the tooth moves towards the oral cavity, root formation occurs passively in the resulting space. Failure of the enamel organ and dental follicle to properly coordinate may result in complications in the eruption process. This clinical report presents 3 cases of isolated, unerupted teeth with dysmorphology of the roots. The process of root development and tooth eruption is also briefly reviewed.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
4/4. osteomyelitis with proliferative periostitis: an unusual case.Chronic osteomyelitis with subperiosteal new bone formation results from periosteal reaction to chronic inflammatory/infectious stimulation. In the maxillofacial region, it has traditionally been termed Garre's osteomyelitis with proliferative periostitis and more recently periostitis ossificans. The term Garre's osteomyelitis has been regarded as a misnomer by many authors in the recent literature. The term chronic osteomyelitis with proliferative periostitis, although cumbersome, is considered to be the most accurate description of the pathology. It usually affects the mandible of young patients secondary to dental infection. Management involves removal of the source of infection and antibiotic treatment. We present an unusual case of chronic osteomyelitis with proliferative periostitis affecting the mandible of a 12-year-old patient. The source of infection was related to the developing lower left third molar, which had apparently no communication with the oral cavity.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
