Dental anomalies in human dentition consist of a considerable variation in size, number, position, shape and structure of the tooth. Microdontia is defined as a condition in which teeth are abnormally smaller in size. Hypodontia is defined as developmental absence of 1–5 teeth excluding third molars. Simultaneous occurrence of multiple dental anomalies is most commonly seen in patients with some abnormality or syndrome; it can also occur in nonsyndromic patients. This case report describes about an unusual simultaneous occurrence of dental anomalies such as localized microdontia of primary teeth and hypodontia in a nonsyndromic 10-year-old male patient. Simultaneous occurrence of multiple dental anomalies in a nonsyndromic patient is rare. As the treatment of such cases involves multiple phases, identification and proper timely management is important to help the patient lead a better quality life.

The objective of this review article is to assess root resorption of conventional rapid maxillary expansion (RME) and mini screw assisted rapid palatal expansion (MARPE) with 2D and 3D radiographic imaging method. For this review article, the current literature was searched on the studies conducted on the effects of such expansion appliances on root resorption. Orthodontic patients with transverse maxillary defieiceny undergo maxillary expansion therapy for the correction of posterior crossbite. The evalution of root resorption in such patients can be done with either 2D radiographs such as perioapical radiograph, panoramic radiograph or 3D radiographs such as cone beam computed tomography. This review article will discuss the studies showing that conventional RME appliances can result in root resorption of molar teeth after the expansion procedure. In contrast, MARPE appliances have not shown significant root resorption after expansion procedures.
