Forgot Password? Introduction The portion of tooth visible within the human mouth, known as the crown, has two main layers of mineralized tissue: enamel and dentin. Reviewed by: Victor E. The instructions suggest that, in general, numeric data between 5 and 25 indicate initial lesions in the enamel and that values greater than this range indicate early dentinal caries. Advanced dentin caries is said to yield values greater than Surprisingly, the device showed higher diagnostic accuracy in the detection of dentinal caries than enamel caries.

The authors suggested that the DIAGNOdent values were dependent on the volume of the caries rather than on the depth of the lesion. With a cut-off of 18 to 22, the sensitivity for diagnosis of dentinal caries in wet teeth was 0. The investigators concluded that overall correlation between DIAGNOdent and microradiography results was moderate but that the device appeared superior to conventional radiography. They reported that the instrument was very sensitive to the presence of stains, deposits and calculus, all of which led to erroneous readings.

Similarly, any changes in the physical structure of the enamel, including disturbed tooth development or mineralization, produced erroneous readings. Second repeated sets of DIAGNOdent measurements showed better cor relation with the microradiography standard, which was construed as revealing operator learning and skill development. Reproducibility for the DIAGNOdent device was high in this study, but there was also evidence of different degrees of learning for individual dentists, and for 2 of the clinicians reproducibility was poor.

The investigators used low cut-off values 10 to 18 for diagnosis and recommended caution in extrapolating their results to the clinical situation. In the end, Lussi and others 4 concluded that, because of its rapidity and very high specificity, visual diagnosis remains the method of first choice and they suggested that this type of examination be carried out before any other technique.

The DIAGNOdent device could then be used for sites of clinical uncertainty, as a second opinion or diagnostic adjunct. The results of Shi and others 6 and Lussi and others, 4 who evaluated the DIAGNOdent device in vitro for the detection of occlusal decay, cannot be directly generalized to clinical practice.

The prevalence of caries in those studies was higher than in the typical clinical situation. Air-dried occlusal surfaces of molars and premolars were examined visually along with bite-wing radiographs if available and with the DIAGNOdent device. The extent of decay was determined by means of an explorer during operative intervention. A high sensitivity 0.

However, the calculated sensitivity was based on a population of teeth with a very high prevalence of caries, since only teeth that appeared clinically to require operative intervention were assessed for the presence of decay. There was a wide range of readings for enamel caries approximately 7 tosuperficial dentinal caries approximately 7 to and deep dentinal caries approximately 12 toand the ranges for each overlapped considerably.

The DIAGNOdent device was not able to distinguish clearly between deep dentinal caries and more superficial dentinal caries. However, the available documentation for its use is limited and involves primarily in vitro studies. Whereas the basic research behind the typical QLF technique, which uses lower wavelength light, is relatively plentiful, little documentation exists for the measurement of enamel fluorescence with the red nm diode laser light source used in the DIAGNOdent system.

For example, there is no basic research to show the correlation between DIAGNOdent measurements and the degree of tooth demineralization. The typical QLF methods use a nm high-pass filter to receive the nm autofluorescent light from enamel and to exclude the lower-wavelength light scattered by the teeth.

In contrast, the DIAGNOdent system uses a nm filter and detects caries by measuring changes in fluorescence intensity rather than by analyzing spectral differences. It is of considerable concern that scientific evidence showing a direct correlation between the numeric DIAGNOdent reading and the severity of disease is lacking. Les bactéries impliquées dans le phénomène sont présentes dans le biofilm à l'état sain. Elles participent à son équilibre et ne sont pas des agents pathogènes à détruire préventivement, d'où l'abandon de l'idée d'un vaccin.

L'évidence du sucre comme cause de la carie a commencé à être remise en question dans les années Les premiers signes peuvent apparaître une fois que la carie a atteint la dentine.

Mais parfois la douleur ne survient que très tardivement, ou même jamais. C'est pourquoi il est vivement conseillé de ne pas attendre d'avoir mal pour consulter un dentiste. Il en ressort que généralement, ce sont les enfants qui sont les plus touchés huile de ricin raidit les cheveux 2014 la carie, surtout les enfants aux bas âges.

On parlera dans ce cas de la carie de la petite enfance [ 25 ]. Un changement majeur dans l'environnement local de la dent peut favoriser le développement de bactéries présentes à l'état sain de la dent. Quand la population de ces bactéries atteint un seuil critique, la carie peut apparaître. Plusieurs espèces de bactéries participent ensuite dans l'évolution de la carie [ 26 ]. Le fluor par voie topique appliqué directement peut ralentir ou stopper la progression de la carie.

Mais une carie non superficielle ne pourra jamais guérir seule, il faut la faire traiter par un dentiste. En l'absence de soins ou de traitements adaptés, la maladie carieuse évolue vers la pulpite puis la nécrose de la pulpe le nerfà la suite de la colonisation de la pulpe par les micro-organismes pathogènes. Cette nécrose est généralement très douloureuse, et peut diffuser par voie endodontique et se compliquer par une infection s'étendant à l'os.

L'infection évolue alors souvent à bas bruit pendant plusieurs mois voire plusieurs années, et n'est parfois détectée que par un contrôle radiographique de routine.

Si un traitement n'est toujours pas entrepris, l'infection continue à se propager. Les dentistes utilisent désormais un détecteur de densité pour mesurer l'ampleur d'une déminéralisation de la dent, cela permet d'éviter une irradiation pour effectuer une radiographie. La dentine est attaquée. La dent commence à être sensible.

Il comble ensuite la cavité créée par l'exérèse des tissus avec un matériau d'obturation biocompatible, généralement un composite dentaireun amalgame dentaire ou par un inlayet un adhésif de dernière génération parfois associé à un agent antibactérien.

Lorsque la carie a atteint un stade avancé dès que les bactéries ont pénétré dans la pulpele dentiste doit dévitaliser la dent pulpectomiepuis obturer les canaux dans lesquels se trouvait la pulpe afin de prévenir une infection bactérienne obturation canalaire. Si la carie a détruit une grande partie de la dent, celle-ci doit être reconstituée avec une couronne.

Lorsque la dent doit être retirée, les nouvelles techniques permettent de placer à la place de la dent retirée une dent de sagesse [réf.
