Effect of two herbal mouthwashes on gingival health of school children.

This study aimed at determining the effect of indigenously prepared neem and mango chewing stick mouthwashes on plaque and gingival indices. A sample of 105 children aged 12-15 years was randomized into three groups, namely neem, mango, and chlorhexidine mouthwash groups. All the children were examined at baseline and gingival and plaque indices were recorded. Baseline scores for plaque and gingivitis were fair and moderate, respectively, in all the three groups and there existed no statistically significant difference among them. Ten millilitres each of herbal and chlorhexidine mouthwashes (0.2%) were administered according to the group allocation twice daily for 21 days. Indices were reassessed at 21 days (immediately after intervention) and at 1 month, 2 months, and 3 months after discontinuing the mouthwashes. Statistically significant reduction (P < 0.001) in plaque index was found in all the three mouthwash groups at 21 days and at 1 month from discontinuing the mouthwash. Chlorhexidine additionally showed statistically significant reduction in plaque index at 2 months from discontinuing the mouthwash. Statistically significant reduction (P < 0.001) in gingival index was found in all the three mouthwash groups at 21 days (immediately after discontinuing the mouthwash) and at 1 and 2 months from discontinuing the mouthwash. To conclude, all the three mouthwashes were effective antiplaque and antigingivitis agents. Chlorhexidine and neem possess equivalent efficacy in reducing plaque, while chlorhexidine has superior antigingivitis properties.

Relationship between serum lithium, salivary lithium, and urinary lithium in patients on lithium therapy.

Lithium carbonate is used in the treatment of both psychiatric and nonpsychiatric disorders. The aim of this study was to explore the relationship between serum lithium, salivary lithium, and urinary lithium. Blood, saliva, and urine samples were collected from 50 patients, and estimation of serum, salivary, and urine lithium was done using an atomic absorption spectrophotometer. Mean serum lithium was 0.75 ± 0.25 mEq/L, mean salivary lithium was 1.91 ± 0.80 mEq/L, and mean urine lithium was 7.16 ± 4.84 mEq/L. A significant direct correlation was found between serum lithium and salivary lithium (r = 0.695, p < 0.001). This correlation was higher in females (r = 0.770, p < 0.001) when compared to males (r = 0.665, p < 0.001). Even though a significant correlation was found between serum and salivary lithium levels, more studies are needed in this domain to establish salivary therapeutic monitoring as a feasible option for patients on lithium carbonate therapy.
