There has been disagreement for more than 100 years concerning the presence or absence of deciduous and successional third premolars in dentition Australian dasyurid marsupial Dasyurus viverrinus as well other species genus Dasyurus. Most authors during 19th 20th centuries have considered missing premolar to be family both jaws, part because reduction size many genera dasyurids. While authors, ...

Dilacerations generally involve central incisors; most often maxillary incisors rather than their mandibular counterparts. The clinical features of dilaceration include non-eruption the responsible tooth or prolonged retention deciduous predecessor tooth. In Case 1, showed a at boundary between crown and root, more laterally labiolingually. 2, dilacerated with relatively normal orientation dent...

An ideal primary dentition is the indicator of future ideal permanent dentition. Absence of primate or secondary spaces in the primary dentition is expression of disproportion between jaw/tooth sizes. Little information is known on the relationship of spacing and closed dentition with malocclusion in relation to primary and permanent dentition. Hence, the present study was conducted to find the...

Transposition of teeth is a severe problem, which usually affects the cuspid-first premolar area. It is frequently associated with other dental anomalies such as tooth agenesis, peg-shaped maxillary lateral incisors, retained deciduous teeth, malpositions of the adjacent teeth and other teeth malformations. This paper describes the orthodontic management with fixed appliances of a case of bilat...

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...

Anti-dentin autoantibodies are associated with inflammatory root resorption in permanent teeth and are modulated by dental trauma and orthodontic force. However, it is not known whether deciduous tooth trauma can stimulate the development of a humoral immune response against dentin. The aim of this study was to evaluate the levels of salivary SIgA reactivity against human dentin extract in youn...

Brook A. Niemiec DVM Southern California Veterinary Dental Specialties A deciduous malocclusion is one that is not standard for the breed which occurs during the deciduous phase of dentition. Any class of malocclusion can present in the deciduous phase, however jaw length discrepancies are more commonly seen at this time. Moreover, these malocclusions may be temporary or develop into a permanen...

Dental caries is the most common chronic childhood disease. Deep caries and dental trauma are the two main etiologic factors responsible for pulp involvement. Better knowledge of the morphology of the root canals of deciduous teeth can improve the outcome of pulp treatment. In this study, 90 deciduous molar teeth (27 first mandibular molars, 27 first maxillary molars, 22 second mandibular molar...

To isolate high-quality human postnatal stem cells from accessible resources is an important goal for stem-cell research. In this study we found that exfoliated human deciduous tooth contains multipotent stem cells [stem cells from human exfoliated deciduous teeth (SHED)]. SHED were identified to be a population of highly proliferative, clonogenic cells capable of differentiating into a variety...

Trauma to primary teeth can lead to devastating sequels in development of permanent successors. The disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. Crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. This report presents a mandibular central incisor with dil...
