Dilaceration is a comparatively uncommon dental deformity generally characterized by an angulation between crown and root, and consequently causing non-eruption of the tooth. Dilaceration generally occurs following trauma to the apices of deciduous dentition, which lies close to the permanent tooth buds. As a result, surgical extraction used to be the first choice when making the treatment plan...

Dilaceration of the permanent tooth usually is a consequence of traumatic injuries to the primary teeth. Although it may appear anywhere in the long axis of the tooth, i.e., crown, cementoenamel junction, or root, most often the root is involved. However, crown dilaceration is a rare condition representing 3% of the total injuries. Maxillary incisors are more susceptible to such injury and affe...

The unique morphology of dilacerated and S-shaped root canals often poses utmost challenges in their endodontic management. Dilaceration is defined as developmental anomaly which there has been an abrupt change the axial inclination between crown a tooth. Periapical radiographs CBCT are most appropriate way to diagnose presence dilacerations. Also, clinician required have insight tooth related ...

When a primary tooth sustains a traumatic injury, development of the permanent tooth can be disturbed, leading to various malformations. This case report details the 7-year follow-up of a developmental anomaly of a central mandibular incisor in a 10-year-old Japanese girl with a history of dental trauma that had occurred at age 4. The trauma had resulted in unusual crown dilaceration in the per...

Taurodontism and root dilaceration are developmental anomalies. Both taurodontism might be related with cleft lip palate (CLP). This study aimed to investigate the prevalence of dilaceration, in children CLP. Cone beam computed tomography images 200 (100 100 healthy) CLP were evaluated retrospectively. level was divided into three subtypes as hypertaurodont, mesotaurodont hypotaurodont. Root re...

PURPOSE To describe the features of impacted upper canines and their relationship with adjacent structures through three-dimensional cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS Using the CBCT scans of 79 upper impacted canines, we evaluated the following parameters: gender, unilateral/bilateral occurrence, location, presence and degree of root resorption of adjacent tee...

The upper second premolars are often known to be interfered with the normal development of their roots by the periapical disturbance of the precursor and its adjacent teeth and, in some cases, by the position of floor of the maxillary sinus. This phenomenon called dilaceration is usually characterized by a crease or bend at the junction of the crown and root [1]. In our 10-year consecutive surv...

An apparently healthy 12-year-old boy was referred to the Department of Oral and Maxillofacial Pathology whose chief complaint was the presence of an additional tooth in the upper front teeth region. His medical, dental and family history was not relevant. Intraoral examination revealed an erupted, supernumerary tooth palatal to permanent maxillary right central incisor and radiograph revealed ...

OBJECTIVES To determine the prevalence of developmental dental anomalies in patients attending the Dental Faculty of Medical University of Yazd, Iran and the gender differences of these anomalies. DESIGN A retrospective study based on the panoramic radiographs of 480 patients. Patients referred for panoramic radiographs were clinically examined, a detailed family history of any dental anomali...

Successful root canal therapy requires a thorough knowledge of root anatomy and root canal morphology which may be quiet variable. The significance of internal root canal morphology has been emphasized by studies demonstrating that variations in canal morphology may affect the endodontic outcome. Consequently, in treating each tooth the clinician must assume that complex anatomy occurs often en...
