“…Vandana et al reported that there is a strong association of occurrence of periodontal disease and dental fluorosis [ 48 ]. The more serious dental fluorosis is, the rougher the tooth surface is, which makes periodontal bacteria easier to colonize on the tooth surface and difficult for scaling and root planning and may promote the occurrence of periodontal disease [ 49 ]. Treponema lecithinolyticum is a dominant specie related to the incidence of periodontitis [ 50 ]; our study also showed a relative high abundance of Treponema lecithinolyticum in the DF group compared with the HC group, suggesting that there may be a potentially high risk of periodontitis in the dental fluorosis population.…”

Background We aimed to explore saliva microbiome alterations in dental fluorosis population. Methods The prevalence of dental fluorosis was examined in 957 college students. Dean’s fluorosis index was used to evaluate the dental fluorosis status. Changes in the composition of the salivary microbiome were assessed in a subset of these patients (100 healthy controls, 100 dental fluorosis patients). Results Dental fluorosis affected 47% of the student sample, and incidence was unrelated to gender. Compared with healthy controls, the microbiota of patients with dental fluorosis exhibited increased diversity, with increased abundance of Treponema lecithinolyticum, Vibrio metschnikovii , Cupriavidus pauculus , Pseudomonas , Pseudomonadaceae , Pseudomonadales , and decreased abundance of Streptococcus mutans , Streptococcus sanguinis , Gemella , and Staphylococcales . Function analyses showed increases in arginine biosynthesis in patients affected by dental fluorosis, together with reductions in amino sugar and nucleotide sugar metabolism, fructose and mannose metabolism, and starch and sucrose metabolism. Conclusions These results suggest that there are striking differences in salivary microbiome between healthy controls and dental fluorosis patients. Dental fluorosis may contribute to periodontitis and systemic lung diseases. There is a need for cohort studies to determine whether altering the salivary microbiota in dental fluorosis patients can alter the development of oral or systemic diseases.

“…The role of some of the etiological factors of periodontal disease such as age, gender, ethnicity, socio-economic status, lifestyle, smoking and oral hygiene has been studied in some populations in India 24 , 25 but the effect of fluoride on periodontal tissue remains controversial, even though its association with tooth decay is well established. 26 The epidemiological data regarding the periodontal status of individuals living in areas with highly fluoridated water are inconsistent. As regards malocclusion, few recent investigations have analyzed and classified dental occlusion in school populations in northern Tanzania.…”

Introduction: Dental fluorosis is endemic in the Rift Valley in Africa, especially around volcanic areas, due to the high fluoride content in daily drinking water. Objective: This study evaluates the oral health status and types of occlusion in a school population, and to assess the possible association between dental fluorosis and other pathologies such as decay, gingivitis and periodontitis. Material and methods: An observational study of 581 individuals recruited from a public secondary school in Arusha, North- ern Tanzania was undertaken. The indices used were: the Silness & Löe Plaque Index, the Community Periodontal Index and the Decayed/Missing/Filled index. Descriptive statistical analyses were performed and a chi-square test was used to assess the associations between independent variables. Results: Almost all the school children evaluated (96.73%) presented Angle class I dental occlusion, and 75.22% presented some degree of dental fluorosis. Most of the population (511, 87.95%) showed bleeding on probing. A moderate/high degree of some dental pathology (DMF score) was recorded in 14.46%. The association between dental fluorosis, gingival bleeding and tooth decay indicated a higher concentration of pathology in groups with more severe fluorosis (p<0.05). Conclusion: In this large population sample, both tooth decay and gingivitis were significantly associated with moderate or severe dental fluorosis. Keywords: Dental fluorosis; caries; periodontal disease; occlusion; community water fluoridation; socio-economic status.

“…[27][28][29] Authors have reported no association between periodontal parameters and fluorosis, 30,31 increased periodontal scores, 5,7 and reduced periodontal scores. 24,32,33 Recently, a review 34,35 has discussed about various detrimental effects of fluoride on periodontal structures. Going by molecular aspect as well, the excess of fluoride in water can not only influence the microbial flora but the influence of this (possibly) altered microbial flora on the already altered/modified oral tissues remains to be studied.…”

Aim Determination of the effect of varying fenestration technique, and simulated patch graft on outflow facility for Baerveldt tube. Materials and methods Silicone tubing similar to Baerveldt implant (AMO, Santa Ana, CA) with different fenestrations techniques was connected to a digital manometer in a closed system with a fluid-filled syringe on a stand to adjust pressure. The venting slits included: (A) 4 piercings with 7–0 TG140-8 needle; (B) a 2-mm slit with a 15° blade; (C) 4 piercings with a 15° blade; (D) 9–0 Nylon on CS140-6 needle with suture stenting the fenestration. Results For pressures of 10, 20, 30, 40 mm Hg in groups A to D, the average outflow facility (mL/min/mm Hg) were group A: 0.11, 0.20, 0.28, 0.40; group B: 0.30, 0.69, 0.98, 0.93; group C: 0.73, 0.80, 0.81, 0.88; group D: 0.58, 0.65, 0.80, 0.87. For external compression with 10 gram weights at pressures of 10, 20, 30, 40 mm Hg, outflow were group A: 0.0, 0.18, 0.20, 0.53; group B: 0.75, 0.70, 0.97, 1.21. Group C: 0.18, 0.03, 0.57, 0.04. Group D: 0.73, 0.90, 1.13, 0.91. Conclusion Effectivity of venting slits in maintaining adequate IOP in the early postoperative period for non-valved glaucoma implant is variable, multifactorial and largely intraocular pressure (IOP) dependent. Clinical significance This study explores methods of producing fenestration and the effects on outflow at different pressures in an attempt to determine which fenestration technique has more reproducible results that can be made applicable in clinical practice. This is also the first study to evaluate the effect of external pressures similar to scleral patch graft on the tube fenestrations.
