For the comparison of these three algorithms, 11 authentic teeth, ranging from premolars to molars, were used. With regard to the detection results and classification accuracies, the proposed superpixel DRLSE method received lower error metric scores than the other methods....
By evaluating pulp in 202 images of six teeth the lower and upper mean values were equivalent with 0 to 1807 Hounsfield units. Reconstructions of three-dimensional models of the pulp system utilised greyscale thresholding based on previous greyscale analyses. Models of the pulp system were viewed ...
Besides smiling, laughing, and communicating, the mouth and teeth serve important functions in the body. Teeth and saliva break down food, making it easier for the stomach to process it further for absorption by the intestines. The teeth provide structural support for the face. The mouth and t...
1) – 3) Initial images. 4) The wire used for the teeth splint is placed next to a periodontal probe. The wire splint is doubled to prevent the tooth from rotating around it after placement. 5) Then the splint is bonded to the lingual surfaces of teeth #’s 25 and 27. 6) Initial...

Flexible Tongue Housed in a Static Model of the Vocal Tract With Jaws, Lips and Teeth Because the thin, acrylic plates on the outside are transparent, the interior of the oral and pharyngeal cavities are visible. When we feed a glottal sound through a hole in the laryngeal region on the ...
Cone-beam computed tomography (CBCT) is a commonly used diagnostic tool in dentistry. CBCT images can illustrate the internal structures of teeth three-dimensionally and accurately at a high resolution while simultaneously eliminating the problem of superimposing anatomical structures by combining sagittal,...
matter, too. Some people do all the oral hygiene stuff right and still get cavities because of the bacteria living in their mouths. Which presents a question: If the types of bacteria in your mouth can make you more prone to cavities, could you fix your teeth by getting different bacteria...
On their own, neutrophils can't damage teeth but the problems arise after acids from bacteria demineralize them. Once weakened, enzymes released by the neutrophils could wreak havoc on other tooth substances. Damage was found to appear in a matter of hours, and worse still, it also seems to...
Salivary mucins, key components of mucus, actively protect the teeth from the cariogenic bacterium, Streptococcus mutans, according to research published ahead of print in Applied and Environmental Microbiology. The research suggests that bolstering nati
