fluoridation is to prevent tooth decay by adjusting the concentration of fluoride in public water supplies. Tooth decay (dental caries) is one of the most Water fluoridation is the controlled addition of fluoride to public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. In the mouth, fluoride slows tooth enamel demineralization and enhances remineralization in early-stage cavities. Defluoridation is necessary when natural fluoride exceed The views on the most effective method for community prevention of tooth decay are mixed. The Australian government review states that water fluoridation is the most effective means of achieving fluoride exposure that is community-wide. The European Commission review states "No obvious advantage appears in favour of water fluoridation compared with topical prevention". Other fluoride therapies are also effective in preventing tooth decay; they include fluoride toothpaste, mouthwash, gel, and varnish, and fluoridation of salt and milk. Dental sealants are effective as well, with estimates of prevented cavities ranging from 33% to 86%, depending on age of sealant and type of study. Fluoride toothpaste is the most widely used and rigorously evaluated fluoride treatment. Its introduction is considered the main reason for the decline in tooth decay in industrialized countries, and toothpaste appears to be the single common factor in countries where tooth decay has declined. Toothpaste is the only realistic fluoride strategy in many low-income countries, where lack of infrastructure renders water or salt fluoridation infeasible. It relies on individual and family behavior, and its use is less likely among lower economic classes; in low-income countries it is unaffordable for the poor. Fluoride toothpaste prevents about 25% of cavities in young permanent teeth, and its effectiveness is improved if higher concentrations of fluoride are used, or if the toothbrushing is supervised. Fluoride mouthwash and gel are about as effective as fluoride toothpaste; fluoride varnish prevents about 45% of cavities. By comparison, brushing with a nonfluoride toothpaste has little effect on cavities. The effectiveness of salt fluoridation is about the same as that of water fluoridation, if most salt for human consumption is fluoridated. Fluoridated salt reaches the consumer in salt at home, in meals at school and at large kitchens, and in bread. For example, Jamaica has just one salt producer, but a complex public water supply; it started fluoridating all salt in 1987, achieving a decline in cavities. Universal salt fluoridation is also practiced in Colombia and the Swiss Canton of…

Background: Dental plaque and gingival inflammation are key etiological factors in the progression of periodontal diseases. While fluoride-based toothpastes are widely used for their anti-caries benefits, their role in controlling gingivitis is limited. Herbal formulations containing neem and clove have shown promising antiplaque and anti-inflammatory effects, but robust clinical comparisons with fluoride toothpastes remain scarce. Objective: To compare the efficacy of a neem–clove herbal toothpaste with a conventional fluoride toothpaste in reducing plaque index (PI) and gingival bleeding index (GBI) over an 8-week period in adults with mild to moderate gingivitis. Methods: A randomized, examiner-blinded, parallel-arm comparative clinical study was conducted involving 70 systemically healthy adults aged 18–65. Participants were randomly assigned to use either a herbal toothpaste containing standardized neem and clove extracts (n = 35) or a conventional fluoride toothpaste (1,450 ppm sodium fluoride, n = 35). Clinical parameters, including PI and GBI, were recorded at baseline, Week 4, and Week 8 by a calibrated examiner using standard indices. Compliance and safety were monitored throughout the study. Results: Both groups demonstrated significant reductions in PI and GBI from baseline to Week 8 (p < 0.001). However, the herbal group showed statistically greater reductions in mean PI at Week 4 (1.48 ± 0.34 vs. 1.57 ± 0.36; p = 0.042) and Week 8 (0.92 ± 0.30 vs. 1.03 ± 0.33; p

Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivi Fluo…
