The Impact of Fruit Juices on the Dental Erosion in Human Tooth Enamel

The difference in the degree of teeth erosion between the adult permanent teeth and the baby primary teeth will also be stressed in this project. The effect of orange juice acid on the dental tubules will also be clearly demonstrated in the experimental project. This is because the two teeth have a different structure and chemical make up and hence respond differently to any form of chemical erosion on their part. Project Aim The use of Scanning Electron Microscope images (SEM) was employed to present a clearer view of the macroscopic effects of the erosive effects of the acid, present in orange juice, on the teeth’s surface. The effects of the obliteration of the dentinal tubules are also clearly evidenced in the SEM images. SEM Analysis of Tooth Enamel The images used in the experiment were taken using a Scanning Electron Microscope. The teeth were placed in a horizontal position, and care was taken to ensure that there was zero degree of tilt. After that, the SEM image pictures were taken at two different magnification levels of 10µm and 200µm for teeth in both categories of adult and primary. The electron acceleration that was used in the experiment was relatively low at 15.0kV and the working distance ranging from between 4.5mm to 7.0mm for both sets of adult and primary teeth depending on the overall size of the tooth. The Images taken by the microscope were then digitized with the help of SEM Image Slave software in order to obtain the quality images displayed1. The use of both back scattered and secondary electrons was employed to produce images. The SEM images in fig 1.4 show the surface of the adult tooth to be rough and scattered with many surface wide fissures and niches. The SEM image in fig 3.3 of the primary tooth shows the baby tooth to be covered with different size and number of particles, which are suggestive of different types of abrasive changes on the biting surface2. Discussion of the SEM Images Analysis of the Scanning Electron Microscope (SEM) Samples From the Scanning Electron Microscope image of the controlled tooth without any effect in fig 2.1, it can clearly be seen that there is an overall erosion of the entire smear layer of the tooth after its immersion in orange juice. The appearance of macroscopic lesions on the surface of the tooth after its immersion in orange juice is a clear indication of the erosive nature of the liquid. The result obtained is not much different from the one shown in the fig 1.1 of controlled tooth 1, which shows a normal human tooth viewed at 200µm; the tooth appears to be normal with a few deep lesions on its surface that can be ascribed to characteristic wear and tear due to the tooth’s normal activities while in the oral cavity. The surface appears to be smooth and not suffering from signs of any previous tooth erosion or any other tooth defect3. The figure 1.2 of controlled tooth 2 viewed at 200µm shows a normally developed adult permanent tooth. The tooth appears to be normal with a few deep lesions on its surface. The tooth also seems to have more pronounced chipping as compared to the previous tooth in figure 1.1. No dental caries or any other defect can be detected on the tooth’s surface. The figure 1.3 of controlled tooth 3 that is being viewed at a magnification level of 10µm shows a clear lesion on the tooth’ ...Show more

The Impact of Fruit Juices on the Dental Erosion in Human Tooth Enamel
The changing lifestyle pattern of human beings which incorporates consumption of acidic substances like soft drinks and fruit juices has been a major contributor for the development and progression of dental erosion. Immense research in this field has strongly indicated a definite connection between the role of fruit juices and soft drinks and the development of dental erosion.

The effect of coffee and tea on dental erosion
When either tea or coffee is consumed, the tannic acid finds its way to the grooves and pits of the enamel of the teeth as a result of which, the teeth may stain yellow and then brown in extreme cases. The hygiene of teeth is a fundamental part of the overall health of an individual.

Dental Erosion in Human Tooth When Exposed to Coffee and Tea
Current paper focuses on dental erosion as related to the consumption of drinks like coffee and tea. Dental erosion can cause severe damages to the teeth, especially if it is not treated on time. The empirical research developed in this field proved that the risks for dental erosion caused by food and drinks are not similar; for instance, soft drinks are more likely to cause dental erosion compared to tea, the erosive effect of which is quite limited – compared to soft drinks, as proved through the research developed for this paper.
