Supernumerary teeth are more common in the permanent than the primary dentition. In the latter, the majority occur in the maxillary lateral incisor region or as a mesiodens. Indeed, in one study conducted in the USA, all 26 cases of primary supernumerary teeth examined were found to be lateral incisors. ...

In some periodontal cases, biomechanical, esthetic, medical, or economic concerns make it difficult for clinicians to employ either traditional therapy or restoration with an implant-supported prosthesis. To avoid any compromise and ensure a good result in such cases, we chose a removable telescopic prosthesis on natural teeth. In this paper ...

Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. ...

Impactions with severely dilacerated root is seldom reported, especially the maxillary incisor. It is probably because of the high clinical difficulty of bringing the dilacerated tooth into position: most patients probably would choose extraction with replacement by prosthesis instead. However, the philosophy seems to have changed recently. We report two ...

Root resorption often occurs after tooth trauma and may also occur during orthodontic tooth movement. This has been attributed to bacteria and inflammation or a combination of both aetiologies. The literature suggests that root canal treatment performed on a traumatized tooth that will concurrently or subsequently undergo orthodontic tooth movement ...
