Afibrillar dental cementum in the rat and hamster
Journal of Periodontal Research, 1975Afibrillar cementum “spurs” have been observed as a direct coronal extension of fibrillar root cementum near the cemento‐enamel junction of rat molars. It was also present as a localized deposit over the dentin surface of a hamster mandibular molar near the bifurcation.

Fluoride concentration of dental calculus, surface enamel and cementum
Archives of Oral Biology, 1963Abstract Fluoride concentrations were determined in samples of cementum, surface enamel, supra- and sub-gingival calculus of ninety-one permanent human teeth. The cementum and surface enamel were removed by grinding from the root surfaces and peripheral enamel. The supra- and sub-gingival calculus were scaled off. Significant differences between the

PIXE analysis of human dental cementum
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1984Abstract The elemental composition of dental cementum, from teeth of children with ages between 11 and 14 years, has been determined using the well-established PIXE technique. This was carried out in situ, that is, without having to remove the cementum from the dental roots, and thus avoiding any contamination.

A microradiographic comparison of sound and carious human dental cementum
Archives of Oral Biology, 1968Abstract The mineral distribution in sound and carious human acellular and cellular cementum was studied by microradiography of thin sections. Observations on the sound tissue confirmed the occurrence of alternating bands of high and low mineral content and also the formation of a densely mineralized layer at the external surface of cementum exposed ...

Formation of Acellular Root Cementum in to Dental and Non-dental Hard Tissues in the Rat
Journal of Dental Research, 1990After the periodontium of the rat was wounded, the formation of acellular extrinsic fiber cementum (AEFC) did not appear to be restricted to the hard dental tissues (pre-existing cementum, dentin, and enamel). Layers resembling AEFC were also deposited along the inner wall of the alveolar bone. At the time of observation (six weeks after being wounded)

Ti:sapphire femtosecond laser ablation of dental enamel, dentine, and cementum
Lasers in Medical Science, 2011This paper reports an investigation into the characteristics of femtosecond laser (800-nm central wavelength) in the ablation of human dental enamel, dentine, and cementum at various laser fluences from 0.2 to 3.68 J/cm(2) with single and multiple pulses. The femtosecond laser interaction with cementum is reported for the first time.

Distribution of fluoride across human dental enamel, dentine and cementum
Archives of Oral Biology, 1987This was determined across the entire width of sections from 20 mandibular premolars, containing enamel, coronal dentine, root dentine and cementum. An abrasive technique was used to sample all three dental tissues in a single experiment. In the profiles of fluoride distribution, fluoride concentration was thus precisely related to the position of the ...

Observations of the Periodontal Ligament and Cementum in Cats with Dental Resorptive Lesions
Journal of Veterinary Dentistry, 2005The etiology of feline dental resorptive lesions is unknown, but some evidence suggests that interactions between components of the periodontium may be initiating factors in the development of these lesions. In the present study, 22 clinically normal teeth were harvested from 7 cats.
