A review of the effects of stannous fluoride on Gingivitis.
Journal of clinical periodontology, 2006Co-Authors: S.p. Paraskevas, G.a. Van Der WeijdenAbstract:Aim: To review the literature on the effects of stannous fluoride on Gingivitis. Material and Methods: The Medline and cochrane central register of controlled trials were searched up to August 2005 to identify appropriate studies. The primary outcome measure was Gingivitis. Results: Independent screening of titles and abstracts of 542 papers resulted in 36 publications (inter-reviewer e score of 0.76), out of which 15 papers finally fulfilled the criteria of eligibility. For SnF 2 dentifrices, a statistically significant reduction in Gingivitis was noted in comparison with control (weighted mean difference (WMD) of 0.15 (gingival index) and 0.21 (Gingivitis severity index) (test for heterogeneity p

With regard to plaque reduction inconsistent results existed. On using the plaque index no differences were found, whereas meta-analysis of the Turesky index provided a WMD of 0.31 (p = 0.01, test for heterogeneity p<0.0001, I 2 = 91.7%). Because of insufficient data, a meta-analysis for SnF 2 mouth rinse and dentifrice/mouthrinse formulations was not performed. Conclusions: The use of SnF 2 dentifrices results in Gingivitis and plaque reduction when compared with a conventional dentifrice. The precise magnitude of this effect was difficult to assess because of a high level of heterogeneity in study outcomes.

the impacts of Gingivitis and calculus on thai children s quality of life
Journal of Clinical Periodontology, 2012Co-Authors: Sudaduang Krisdapong, Piyada Prasertsom, Khanit Rattanarangsima, Aubrey Sheiham, Georgios TsakosAbstract:Aim To assess associations of socio-demographic, behavioural and the extent of Gingivitis and calculus with oral health-related quality of life (OHRQoL) in nationally representative samples of 12- and 15-year-old Thai children. Material and Methods In the Thailand National Oral Health Survey, 1,063 twelve-year olds and 811 fifteen-year olds were clinically examined and interviewed for OHRQoL using the Child-OIDP and OIDP indices, respectively, and completed a behavioural questionnaire. We assessed associations of condition-specific impacts (CS-impacts) with Gingivitis and calculus, adjusted for socio-demographic and behavioural factors. Results Gingivitis and calculus were highly prevalent: 79.3% in 12-year and 81.5% in 15-year olds. CS-impacts relating to calculus and/or Gingivitis were reported by 26.0% of 12-year and 29.6% of 15-year olds. Except for calculus without Gingivitis, calculus and/or Gingivitis in any form was significantly related to any level of CS-impacts. At a moderate or higher level of CS-impacts, there were significant relationships with extensive calculus and/or Gingivitis in 12-year olds and for extensive Gingivitis and Gingivitis without calculus in 15-year olds. Conclusions Gingivitis was generally associated with any level of CS-impacts attributed to calculus and/or Gingivitis. CS-impacts were related more to Gingivitis than to calculus.

Is the chemical prevention of Gingivitis necessary to prevent severe periodontitis
Periodontology 2000, 1997Co-Authors: Aubrey SheihamAbstract:Gingival inflammation seldom causes discomfort, social embarrassment or loss of function. As most sites with gingival inflammation do not progress to severe periodontal disease, Gingivitis should not be considered a public health problem. Periodontitis is always preceded by Gingivitis. But most Gingivitis remains stable for years without progressing to periodontitis. The number of Gingivitis sites that do convert is small. The levels of oral cleanliness achieved by the majority of populations in industrialized countries are below the threshold for severe destructive periodontal disease of personal and public health concern. Because methods of measuring the progression of periodontal disease are unreliable, definitive answers regarding conversion of Gingivitis to severe periodontitis are lacking. Gingival inflammation frequently remains contained; most Gingivitis remains stable for years without progressing to periodontitis. Decreasing Gingivitis does reduce shallow pocketing, but the effect on severe periodontitis is not clear. Although the underlying justification for the reduction of plaque is to reduce gingival inflammation to prevent or reduce severe periodontitis and tooth loss, the basis for the approach is equivocal. A reasonably high level of plaque appears to be compatible with acceptably low levels of periodontal disease. Reducing nonspecific plaque levels to such levels is therefore a rational goal. The conventional methods of controlling periodontal disease involve mechanical removal of plaque and calculus. A complimentary ecological approach, using chemicals, would be to alter the environment of the pocket to prevent growth of putative pathogens. Any ecological approach should be sensitive to the dangers of disrupting the natural ecology of dental plaque. Some antimicrobial and antimetabolic agents such as fluoride, chlorhexidine and triclosan and zinc citrate can selectively suppress certain organisms or inhibit bacterial proteases implicated in tissue damage. The uncertainties about factors that convert gingival inflammation into periodontitis and periodontitis into severe periodontitis coupled with insufficient data from controlled clinical trials on the effectiveness of chemical reduction of Gingivitis to prevent severe periodontitis leads one to conclude that more research is required before the need for the chemical prevention of Gingivitis to prevent severe periodontitis can be justified.

Bacterial community development in experimental Gingivitis.
PloS one, 2013Co-Authors: James O Kistler, Veronica Booth, David J. Bradshaw, William G. WadeAbstract:Current knowledge of the microbial composition of dental plaque in early Gingivitis is based largely on microscopy and cultural methods, which do not provide a comprehensive description of oral microbial communities. This study used 454-pyrosequencing of the V1–V3 region of 16S rRNA genes (approximately 500 bp), and bacterial culture, to characterize the composition of plaque during the transition from periodontal health to Gingivitis. A total of 20 healthy volunteers abstained from oral hygiene for two weeks, allowing plaque to accumulate and Gingivitis to develop. Plaque samples were analyzed at baseline, and after one and two weeks. In addition, plaque samples from 20 chronic periodontitis patients were analyzed for cross-sectional comparison to the experimental Gingivitis cohort. All of the healthy volunteers developed Gingivitis after two weeks. Pyrosequencing yielded a final total of 344 267 sequences after filtering, with a mean length of 354 bases, that were clustered into an average of 299 species-level Operational Taxonomic Units (OTUs) per sample. Principal coordinates analysis (PCoA) plots revealed significant shifts in the bacterial community structure of plaque as Gingivitis was induced, and community diversity increased significantly after two weeks. Changes in the relative abundance of OTUs during the transition from health to Gingivitis were correlated to bleeding on probing (BoP) scores and resulted in the identification of new health- and Gingivitis-associated taxa. Comparison of the healthy volunteers to the periodontitis patients also confirmed the association of a number of putative periodontal pathogens with chronic periodontitis. Taxa associated with Gingivitis included Fusobacterium nucleatum subsp. polymorphum, Lachnospiraceae [G-2] sp. HOT100, Lautropia sp. HOTA94, and Prevotella oulorum, whilst Rothia dentocariosa was associated with periodontal health. Further study of these taxa is warranted and may lead to new therapeutic approaches to prevent periodontal disease.

Does Gingivitis lead to periodontitis in young adults
Lancet (London England), 1993Co-Authors: S W Prayitno, Martin Addy, William G. WadeAbstract:It has been assumed that poor oral hygiene predisposes to Gingivitis with progression to periodontitis and tooth loss. However, a high prevalence of Gingivitis occurs in some populations in which severe periodontitis is rare. To assess whether Gingivitis is a reliable predictor of periodontitis, we compared the periodontal health of tea pickers and university students aged between 18 and 30 in Indonesia. Oral hygiene and gingival health was significantly better in students than in tea pickers. However, the prevalence and the severity of chronic periodontitis were similar in the two groups. Our findings suggest that Gingivitis is a poor predictor of periodontitis in subjects younger than 30 years. Attempts to prevent periodontitis in young adults through antiGingivitis measures such as plaque control may be unsuccessful.
