The objective of this study was to determine the relationship between the amount of dentifrice used, salivary flow and rinsing after brushing to the retention of residual fluoride from dentifrice use in 40 children aged (5-11) years in Bangalore City. The children were asked to brush their teeth under supervision with the given paste and brush and subsequently rinse thrice with measured amounts of the provided water. All expectorations were collected and analysed for fluorides using a fluoride ion-specific electrode. The salivary flow/min was measured separately. The amount of dentifrice used noted. These three factors were then correlated with ingestion of fluoride. The striking features of this study were: (a) Increasing ingestion with usage of a dentifrice amount greater than 6 gms. (b) There is no significant variation in ingestion to the amount of saliva secreted. (c) There is a strong correation between rinsing and ingestion. Rinsing thrice reduced ingestion by 25%. Results show that fluoride dentifrice user must be properly educated to rinse as many times as possible, after brushing, to reduce excess fluoride ingestion. |
