Dens invaginatus is a developmental dental anomaly characterized by the infolding of the enamel organ into the dental papilla during early odontogenesis. This process leads to a broad spectrum of anatomical variations, ranging from minor enamel-lined pits confined to the crown to deep invaginations extending through the root, occasionally communicating with periodontal or periapical tissues. The internal complexity of affected teeth presents diagnostic and therapeutic challenges, particularly in severe forms that mimic root canal systems or are associated with pulpal or periapical pathology. Maxillary lateral incisors are most frequently affected, likely due to their unique developmental timeline and morphological susceptibility. Although various classification systems have been proposed, Oehlers’ classification remains the most clinically relevant due to its simplicity and correlation with treatment complexity. Recent advances in diagnostic imaging, especially cone beam computed tomography (CBCT), have revolutionized the identification and classification of these anomalies. CBCT-based adaptations of Oehlers’ classification allow for the precise assessment of invagination extent and pulpal involvement, facilitating improved treatment planning. Contemporary therapeutic strategies now include calcium-silicate-based cement sealing materials, endodontic microsurgery for inaccessible anatomy, and regenerative endodontic procedures for immature teeth with necrotic pulps. Emerging developments in artificial intelligence, genetic research, and tissue engineering promise to further refine diagnostic capabilities and treatment options. Early detection remains critical to prevent complications such as pulpal necrosis or apical disease. A multidisciplinary, image-guided, and patient-centered approach is essential for optimizing clinical outcomes in cases of dens invaginatus.

O contrato de concessão e a permissão possuem caracterísitas próprias, muitas delas constitucionais, a exemplo, da regra da licitação. Desse modo, importante realizar um estudo jurídico da Lei Ordinária nº 3015, de 17 de maio de 2002, do Município de Aracaju. Trata-se, em verdade, de uma pesquisa, quanto à abordagem, qualitativa, como também, bibliográfica-documental, pois, vale-se de fontes primárias e secundárias. Dessa maneira, constata-se que a transferência onerosa ou gratuita da concessão e permissão, aceita pela lei em análise, desrespeita a natureza personalíssima do instituto contratual, além de afrontar o que regra a Constituição Federal.

A complex pneumothorax is a loculated pneumothorax due to adhesions. Chest roentgenograms are usually inadequate to assess a complex pneumothorax. A computed tomography (CT) scan can be used to accurately assess the extent of the pneumothorax, and to determine its exact location in order to make placement of a tube thoracostomy easier and safer. In addition, if there is a persistent or recurrent pneumothorax after tube thoracostomy, a CT scan can be used to determine the relationship of the chest tube to the pneumothorax. Three cases are discussed to illustrate the use of the CT scan in evaluating patients who have a complex pneumothorax.
