“…Armitage et al (1983) observed a change in the cementum of teeth with heavily infected root canals. This change was very much like changes in the cementum of periodontally compromised teeth found in earlier studies, both considering their form and location (Bass 1951, Benson 1963, Armitage & Christie 1973, Armitage 1977, Bigarre & Yardin 1977). Although studies questioned the importance of “diseased” cementum for the results of periodontal therapy (Nyman et al 1988, Corbet et al 1993), the role of this feature in the pathogenesis of periodontitis was never denied nor confirmed in subsequent research.…”

“…8,9 Clinicians have shown interest in alterations of cementum associ ated with periodontal disease such as pathologic gran ules. 10 root roughness, 11 softness, 12 and ultrastructural changes. 13 Probably because of sampling difficulties, little infor mation is available on the chemical composition of cementum.…”

A study was conducted to determine the values of several chemical components of dental cementum. Extracted teeth from continuous residents of low, optimal, and high natural fluoride areas were selected to determine the effects of fluoride exposure and age on the fluoride, citrate and carbonate content of cervical and apical areas of sound and periodontally diseased human cementum. 1. For normal cementum the mean fluoride content of all 18 groups was 0.443 plus or minus 0.04%on an ash basis and 0.253 plus or minus 0.02% on a dry weight basis; the mean citrate content was 1.52 plus or minus 0.10% on an ash basis and 0.86 plus or minus 0.06% on a dry weight basis; the mean carbonate content was 4.95 plus or minus 0.39% on an ash basis and 2.79 plus or minus 0.22% on a dry weight basis. 2. For diseased cementum the mean fluoride content of all 12 groups was 0.575 plus or minus 0.03% on an ash basis and 0.342 plus or minus 0.02% on a dry weight basis; the mean citrate content was 1.19 plus or minus 0.07% on an ash basis and 0.71 plus or minus 0.05% on a dry weight basis; the mean carbonate content was 5.95 plus or minus 0.47% on an ash basis and 3.50 plus or minus 0.28% on a dry weight basis. 3. There is a general increment in fluoride content of normal cervical and apical cementum, both with age and fluoride exposure. For diseased cementum this held true for fluoride exposure but not age. 4. The mean fluoride content of cervical cementum is greater than that of apical cementum for both normal and diseased groups. For citrate and carbonate no definite statistical differences were noted between cervical and apical areas. 5. The diseased cementum has a significantly higher mean fluoride content, a significantly lower citrate content, and a slightly, but not statistically significant, higher carbonate content than normal cementum. 6. Unlike bone, no inverse fluoride/citrate or fluoride/carbonate relationship was observed. 7. For both normal and diseased groups the carbonate content of cementum of individuals over age 40 tended to be lower than for individuals 20-40 years of age.

“…The most common changes in exposed cementum have been depicted as (a) increased mineralization, probably a reflection of surface mineralization from salivary compo nents, (b) demineralization, possibly in relation with root caries, and (c) the presence of refractile granules which may represent areas of collagen degeneration. 17,18,[20][21][22] At the ultrastructural level, increased as well as de creased surface mineralization has been seen. 19,23,24 In addition, bacterial penetration has also been observed.…”
