28,32 Despite these potential explanations, the exact mechanism of the anti-inflammatory action of L. sidoides is still unknown, and further www.selleckchem.com/products/Y-27632.html studies are required. The BI is a generally used dichotomous index for evaluation of gingivitis10,13,14, but it does not assess the severity of gingival inflammation. Studies evaluating the reduction of gingivitis by a grading index could be interesting to complement these results, as used in other works evaluating herbal agents.12,22,33 However, color change, used as a parameter in this grading index, is not necessarily an accurate indicator of gingivitis.33 Furthermore, laboratory tests such as enzyme immunoassays of gingival crevicular fluid would be required for a better understanding of the role of L. sidoides preparations as effective agents for gingivitis control.
Home-use studies are often influenced by a number of factors which can mask the superiority of a test agent over controls. Participants of clinical trials may experience some improvement not specifically associated to the therapeutic properties of the test agent, but rather related to a behavioral change; this is known as the Hawthorne effect.14,34 Subjects enrolled in oral hygiene studies usually improve their tooth brushing irrespective of the product they receive.14,34 Although the volunteers in the present study were not aware of which gel they were using, another main factor is the so-called novelty effect, which is the motivation to improve oral hygiene practices induced by the use of a new substance. In contrast, lack of compliance with correct use of the gel can occur as well.
14,34 In order to minimize this potential, participants were asked to bring the bottle at the end of the trial, so we could perform an indirect assessment of compliance. The reduction in gingivitis observed Drug_discovery in both test groups showed that participants used the product correctly, at least to some extent. Finally, the results showed that LS was an effective herbal antigingivitis agent, with performance similar to that of chlorhexidine digluconate, and could be advantageous in cases where patients spend little time on toothbrushing. Further clinical studies are required to evaluate the action of this herbal agent in other oral diseases, such as chronic periodontitis. CONCLUSION A gel formulation containing 10% L. sidoides essential oil was an efficient antiplaque and antigingivitis agent.
The conventional glass ionomer cement (GIC) has been advocated as a restorative material because of its ability to chemically bond to tooth structures1,2 and release fluoride.
