A tooth displaced down into alveolar bone is an intrusive luxation. This injury usually is accompanied by comminution of alveolar fracture. The dislocation is frequently axial and radiographic examination reveals absence of periodontal space. The primary site for luxation injuries is the maxillary anterior region in the primary and permanent dentition with frequency higher in the primary dentit...

Dens evaginatus (DE) is a rare developmental anomaly characterized by presence of an extra cusp arising from occlusal or lingual surfaces. Isolated occurrence or concomitant presence of DE with other dental anomalies has been reported. DE commonly affects permanent teeth and is rarely seen in primary dentition. Treatment may be conservative or radical. This article presents two unusual cases of...

Traumatic injuries to primary dentition may interfere with the development of permanent dentition. Among the many malformations, dilaceration is particularly important to the clinician. Management of dilacerated maxillary central incisor requires a multidisciplinary approach. The main purpose of this review is to present the etiological factors, the mechanism, clinical features, radiographic fe...

This article reports the case of a Brazilian child diagnosed with Kabuki make-up syndrome (KMS), addressing the clinical features observed, with emphasis on the disease-specific oral and craniofacial manifestations. The patient had the distinctive KMS craniofacial appearance, mild delayed mental development, fingers with prominent fingertip pads and visual deficit. The dental findings included ...

A talon cusp is a dental anomaly commonly occurring in the permanent dentition compared to the primary dentition. It commonly affects the maxillary anterior teeth. In primary dentition, the most commonly affected tooth is the maxillary central incisors. This is a rare case report of a 5-year-old male patient with a talon cusp affecting the mandibular primary lateral incisor. Recognition and tre...

A method of recording incisor inclination is described using the Tooth inclination Protractor (TIP). This instrument was used to record incisor inclination on dental casts. The scores were related to traditionally determined inclinations for the upper incisor to maxillary plane and the lower incisor to mandibular plane from the lateral cephalometric radiograph. The TIP scores were closely relat...

SETTING School dental clinic, New Territories, Hong Kong. PATIENTS The dental records of children with a history of dental luxation and/or avulsion injury between November 2005 and October 2012 were reviewed. ...
