The relationship of the periodontal status to fluoride levels of alveolar bone and tooth roots

Abstract

The periodontal status and fluoride levels of alveolar bone and tooth roots were compared for subjects from a high (2.5 ppm F) and a low (less than 0.05 ppm F) fluoride area. The plaque index, gingival index, probing depth and loss of attachment were measured to determine the periodontal status. The fluoride levels were determined by the use of the fluoride ion-selective electrode. Both communities had high plaque and gingival indices. However, the mean pocket probing depths in both communities were less than 2.5 mm. No statistically significant differences could be found in the periodontal status between the 2 areas. The fluoride levels in bone and root were higher for subjects from the high fluoride area. No statistically significant difference could be demonstrated between the fluoride levels in alveolar bone and tooth roots for each area. It was found that the fluoride levels in bone and roots increased with increasing age, but to a lesser degree for subjects from the low fluoride area.

Fluoride - an adjunctive therapeutic agent for periodontal disease? Evidence from a cross-sectional study

“…While, Reddy et al (15) observed that the prevalence and severity of periodontitis was not influenced by fluoride content. Another study (7) compared the periodontal status between two localities with fluoride level more than 1.2 ppm and 0.1 pm respectively using Russell's periodontal index.…”

“…They ascribed this result to the formation of fluoroapatite or to the effect on osteoclasts. While, another study (15) reported that the conversion of hydroxyapatite to fluoroapatite in cementum in high fluoride area renders the periodontium resistant to breakdown. Alternatively fluoride may indirectly influence the periodontal status by definite decrease in plaque accumulation from low to high fluoride areas as reported by Anuradha et al (16).…”

Carious lesions as evidence for different adaptation strategies during the middle-late Holocene in the Gansu region, northwest China

“…Additionally, fluoride fortifies tooth enamel’s resistance to acid erosion and impedes bacterial growth and reproduction (Paine et al, 1998; Ten Cate, 1999). Fluoride, however, does little to alleviate periodontal disease (Perry, 1982; Reddy and Grobler, 1988). Therefore, the lower dental caries prevalence in the GGY population was possibly a result of the geological context in which the population lived.…”
