A 5-year-old Caucasian male presented with early loss of multiple deciduous teeth. All the characteristics were consistent with the diagnosis of regional odontodysplasia (ROD). Significant initial findings included premature loss of multiple primary mandibular teeth and some malformed permanent teeth. The affected teeth showed hypoplastic enamel and dentin, short roots, and wide pulp chambers, ...

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...

Schwartz ('74) proposed revised homologies of the deciduous and permanent anterior teeth in living lemuriform primates of the family Indriidae. Gingerich ('77) described a juvenile specimen of Avahi and emphasized the importance of functional integrity in controlling the pattern of dental reduction in primates, neither of which supports Schwartz's interpretation. Schwartz ('78) recently reitera...

Avulsion and luxation account for up to 16% of all traumatic injuries in the permanent dentition and 7.2% of injuries in the primary dentition. A range of treatment options are available that can help conserve the tooth after a traumatic episode. There are, however, occasions where loss of the traumatized tooth is inevitable with special regard to avulsion injuries. replantation of teeth having...

Corresponding Author : Dr. Rekha Sharma Department of Orthodontics PDM Dental College & Research Institute Bahadurgarh-124507, Haryana (India) Apical root resorption is a common idiopathic problem associated with orthodontic treatment that results in permanent loss of tooth structure from the root apex. It has recently received considerable attention because of medico-legal exposure. Root resor...

OBJECTIVE To compare the actual sum of canine and premolars and that predicted from three mixed dentition prediction methods in orthodontic patients at the Aga Khan University Hospital (AKUH), Karachi. STUDY DESIGN Cross-sectional comparative study. PLACE AND DURATION OF STUDY Orthodontic clinic at the Aga Khan University Hospital from June 2002 to December 2007. METHODOLOGY Data were col...

The purpose of the present study was to investigate persistent primary second molars in a group of young people in their late twenties with agenesis of one or two second premolars. In 1982-83 it was decided, in connection with the orthodontic evaluation of 25 patients, to allow 35 primary molars (one or two in each patient) to remain in situ. All patients had mixed dentitions and agenesis of on...

Background: The eruption of the first permanent molar (FPM) marks beginning mixed dentition, which is one most dynamic periods in development and growth stomatognathic system. Aim: purpose study was to investigate pathology during transition stage between primary dentition. Materials Methods: A literature search performed Clarivate Web Science, Google Scholar, PubMed databases. Cohort cross-sec...

Dentofacial injuries that occur prior to the eruption of primary teeth can result in developmental disturbances not only in the primary but also in permanent dentition. Here we report a rare case of long term sequelae of trauma in a female child of 4 to 5 months of age which resulted in dilaceration and impaction of maxillary primary central incisors and subsequent enamel hypoplasia of the perm...
