The Micrograph image of early experimental dental caries in permanent teeth

(Hanoi Medical University, Vietnam, 2016)

 Abstrak

Study on the structure and the mechanism of the formation of early caries is an important premise for evaluating
the caries-preventive methods. Objective: To describe micrograph images of experimental carious lesions
at early stage in permanent teeth in Vietnamese. Methods: There were 60 permanent extracted premolars from
patients aged 18-25 used in this study. After cleaning and removing the remaining soft tissue, each tooth was
painted with acid-resistant coating leaving an enamel window of approximately 1 × 1mm2
on the buccal surface.
The artificial carious lesion was performed by soaking the teeth for 96 hours in the demineralization solution and
evaluated using the ICDAS criteria. The tooth specimen was observed under a scanning electronic microscope
(SEM). Results: The experiment resulted 66.7% of ICDAS 1 and 33.3% ICDAS 2 carious lesions. The mean
depth and area of the lesions were 107.6µm and 1.14 µm2
, respectively. The difference in depth and area of lesions
between group ICDAS 1 and ICDAS 2 was significantly statistical with p=0.0001. The micrographs showed that
after being soaked in demineralization solution, enamel surface became rough, enamel rods lost the minerals in
the body more than in the sheath, cross-sectional images showed widened gaps between the rods due to demineralization.
There was a difference in demineralization degree between group ICDAS 1 and 2. Conclusion: The
image of carious lesions was gained after the teeth were soaked in demineralization solution. It showed different
characteristics of the resulted lesions based on ICDAS criteria for early carious lesions using scanning electron
microscope.
