Abstract
Zika virus is a flavivirus (arthropod-borne virus) transmitted primarily by the bite of an infected Aedes mosquito [1]. During the Zika virus pandemic, more than one million confirmed infected patients were reported in Brazil, which predominated in the north and northeast regions (Pernambuco state and others), declaring a national and international emergency [1] (Zousa EP, 2018). Colombia ranked second among Latin American countries, with more than 47,000 cases [2]..... ReadMore
Highlights
With the outgrowing emphasis on the importance of minimally invasive dentistry and preservation of as much as possible of the sound tooth structure, more focus has been put on the estimation of the remaining dentin thickness below the carious lesion
The protective barrier of healthy dentine extending between the pulp chamber and pulpal floor serves the function of protection against mechanical injury and inflammation and is referred to as remaining dentine thickness [3], throughout centuries there have been many arguments about the proper amount of Remaining Dentine Thickness (RDT) to do its function in pulp protection, A 0.5 mm of remaining dentin in deep carious cavities were seen to induce pulpal reactions similar to pulpal exposure [4], while other authors have suggested the necessity of 2mm or 1 mm of remaining dentine thickness for pulpal protection [5,6] but a minimum thickness of 0.5mm and above should always be preserved to maintain the pulpal health [7]
This study is aimed towards determining a viable and reliable method for estimation of remaining dentine thickness before starting caries excavation reducing the incidents of post-operative sensitivities and direct pulpal exposure through finding a logistic and accurate relationship between the amounts of actual remaining dentine thickness and the radiographic remaining dentine thickness
Summary
With the outgrowing emphasis on the importance of minimally invasive dentistry and preservation of as much as possible of the sound tooth structure, more focus has been put on the estimation of the remaining dentin thickness below the carious lesion. As far as today the excavation of caries has been mainly through the experience of the dentists in judging the cavity depths by observing the color changes in the prepared cavity with or without the aid of radiographs, Many parameters have been used to assist the determination of Copyright © All rights are reserved by Rozhyna Peshraw Kamal.
