Prosthodontic Dichotomy Video
Prosthodontics - Occlusion \u0026 Articulators - NBDE Part II Prosthodontic DichotomySupernumerary Prosthodontic Dichotomy occur in excess of the usual number of teeth. Multiple supernumerary teeth are associated with some syndromes like cleidocranial dyplasia and Gardner syndrome. This report describes the occurrence of supernumerary premolar teeth at the same location in two sisters as a non-syndromal trait. General dental practitioners GDP and dental specialists should have the knowledge and skills to diagnose, manage and treat patients with this condition safely and effectively. It will also discuss the prevalence, unique distribution, associated conditions, aetiology and treatment options of this condition.
This paper describes the considerations a dental practitioners should take when they encounter a case of supernumerary teeth. Introduction The development Prosthodontic Dichotomy an increased number of teeth is known as hyperdontia and the additional teeth are thus called as supernumerary teeth. Many authors have also reported familial occurrence of supernumerary teeth. The prevalence of supernumerary premolars ranges from 0.
Introduction
Unlike other supernumerary teeth, supernumerary premolars are highly likely to develope in the mandible than in the upper maxilla. Clinical examination showed a class I molar relation and a rotated lingually displaced second premolar with a supernumerary premolar on the buccal side in upper left region of mouth [ Figure 1 ]. OPG revealed increased radiopacity in relation to coronal portion of 24, 25 due to superimposition of image of supernumerary premolar [ Figure 2 ]. Therefore, on the basis of clinical and radiographic examination extraction of the supernumerary tooth was planned. Figure 1 Supernumerary premolar on buccal side rotating and displacing second premolar palatally on upper left side of dental arch Figure 2 OPG revealing increased radiopacity in coronal portion of 24, 25 due to superimposition Prosthodontic Dichotomy image of supernumerary tooth. Her 20 year old sister who also came for routine clinical examination revealed clinically absent left canine and the presence of a bucally Prosthodontic Dichotomy supernumerary premolar in the same region upper left dental arch as her sister [Fig.

Patient was advised for routine follow up for radiographic examination of the impacted transmigrating Figure 3 http://pinsoftek.com/wp-content/custom/stamps/what-is-abigails-motivation-in-the-crucible.php sister showing supernumerary premolar in Prosthodontic Dichotomy same region upper left dental arch Figure 4 IOPA showing fully erupted supernumerary premolar with transmigrating upper left canine Figure 5 Showing classification of supernumerary teeth Their mother also Prosthodontic Dichotomy a similar history of a palatally erupted extra tooth in the same location which she got extracted few years back due to food lodgment and caries.
Discussion Supernumerary teeth are defined as the teeth which are present in excess of the usual twenty deciduous and thirty-two permanent teeth.
Case Report
Various theories have been postulated to comprehend their process of development and existence with the normal Prosthodontic Dichotomy. Atavism theory suggested read article occurrence of these teeth is rPosthodontic to the phylogenetic reversion to the extinct ancestral human dentition.
Dichotomy theory says that sometimes developing tooth bud can divide into two teeth, giving rise to one ST and Prosthodontic Dichotomy normal tooth. Although a genetic component may exist, environmental factors cannot be neglected in their developement. There are plenty of reports to support the theory of familial tendency of ST with an increased number of ST evident in the relatives of those affected.
Niswander and Sujaku 8 hypothesized that an AR autosomal recessive gene with less penetrance in females may lead to the formation of a ST.]
Very good piece
This business of your hands!
It is a pity, that now I can not express - I hurry up on job. I will be released - I will necessarily express the opinion on this question.
Excuse, not in that section.....
Absolutely with you it agree. In it something is also idea good, I support.
