Aspectos clínicos y morfológicos de los dientes supernumerarios

The hyperdontia teeth is an anomaly of unknown cause, characterized by increased numbers of teeth. It occurs more frequently in the maxilla, preferably in males, and is more common in permanent dentition. The presence of supernumerary teeth can be responsible for alterations in the permanent dentition, such as the delay in the eruption and dislocations. In addition, the patient may have abnormal occlusion, resorption of adjacent teeth and cyst formation. This article describes in a male patient, 9 years old, the presence of two upper right lateral incisor and one upper left lateral incisor, permanent, partially erupted. Radiological examination revealed a second left upper lateral incisor, unerupted. It should be noted that both, in the region of the 1.2 as in 2.2, the teeth showed normal anatomy and not the conoid appearance commonly observed in supernumerary teeth. In our case, in order to perform orthodontic treatment surgical removal of the teeth noted above was indicated.

Case report: Cornelia de Lange Syndrome (CDLS)

The Cornélia of Lange´s syndrome is a genetic anomaly, described and published by Cornelia Catharina of Lange in 1933, however, their aspects were described previously by Winfried Robert Clemens Brechmann in 1916, that’s why it is also known as Brachmann of Lange’s syndrome. The most frequent clinical characteristics include typical face dismorfia, variable degree of mental delay, anomalies of the hands and feet, multiple malformations, retardation of the pre and postnatal physical development and microcephaly variable intellectual compromising. Some facial characteristics are peculiar and they are mixed with the inherited lines of their own family, the united brows, the long lashes, the small nose, the round face, the fine lips and lightly inverted. As oral manifestations they present micrognathia, dental crowding, periodontal disease, delayed dental eruption, enamel hypoplasia, erosion of the enamel and dentine caused by stomach acids of the gastroesophageal reflux and atresia of the dental arches. The purpose of this paper is to present a clinical report of a boy bearer of this syndrome assisted at CAOE - FOA - UNESP, emphasizing the importance of multiprofessional team for the diagnosis and treatment of this syndrome.

Ectopic third molar as a cause of sinusitis

Ectopic third molar teeth are those that are impacted in unusual positions, or that have been displaced and are at a distance from their normal anatomic location. Ectopic eruption of a tooth within the oral cavity is common, but rare in other sites. Ectopic eruption can be associated with developmental disturbances, pathologic processes or iatrogenic activity. Male, 19- years old, with an upper left ectopic third molar located in the maxillary sinus-infraorbital region. The patient reported a bad taste and recurrent sinusitis that had been resistant to treatment. Surgical excision was carried out of the third molar tooth using the Caldwell-Luc approach.
