Name |
Details |
Intervention |
1% Chlorhexidine and 5% sodium fluoride varnish application |
Two-step application procedure
Child will be comfortably seated on the portable dental chair in upright position. Plaque will be
removed from the surfaces of the teeth by wiping with cotton gauze. In the first step, 0.25 mL of
the allocated formulation will be dispensed in the dispensing wells. The teeth will be dried using
cotton gauze and isolated. The formulation will be applied and allowed to dry up while maintaining
complete isolation using suction tips. In the second step, 0.25 mL of 5% NaF varnish will be
dispensed in the dispensing wells and will be applied on all the teeth using an applicator tip by
using paint on technique. Adequate isolation will be ensured by the use of suction tips throughout
the application procedure. After varnish application, the patient will be made to sit with the mouth
open for 4 minutes with adequate suction. Thereafter, children will be advised not to rinse or drink
anything for half an hour. Parents will be informed to give liquid and semisolid food items on the
day of varnish application and avoid tooth brushing at the night. |

Brief Summary
|
Background: Dental caries is a major public health problem worldwide and there exists a relationship with nutritional status, overall growth and development of the child. Recent advancements in preventive dentistry advocate use of an antibacterial agent with topical fluoride to prevent caries incidence effectively. Novelty: Paucity of good quality randomized trials evaluating the added benefit of chlorhexidine or povidone iodine over topical fluoride use alone limits our ability to frame effective caries preventive guidelines for children. The results of this randomized trial will thus help us formulate an effective caries preventive regimen for children. Objectives: To assess and compare the caries preventive effectiveness of antibacterial agent (povidone iodine or chlorhexidine) plus fluoride varnish over fluoride varnish alone among 4–6-year-old children. To correlate the tooth morbidity and nutritional status of the children. Methods: Children will be randomly allocated to one of the three groups (Group 1: 1% chlorhexidine solution followed by 5% fluoride varnish, Group 2: 10% povidone iodine solution followed by 5% fluoride varnish, Group 3: placebo solution followed by 5% fluoride varnish). The three formulations (10% povidone iodine, 1% chlorhexidine and placebo) will be masked indigenously to ensure triple blinding. ICDAS II scores, DIAGNOdent/QLF scores, gingival bleeding index, BMI, and oral microflora including Mutans streptococci will be evaluated at baseline and at follow-ups up to 2 years. Appropriate descriptive and inferential statistics will be applied. Statistical significance is set at p<0.05. Expected outcome: This trial will help evaluate whether semi-annual application of antibacterial agent (povidone iodine or chlorhexidine) along with fluoride varnish is more effective in preventing caries than fluoride varnish application alone among 4–6-year-old children. Caries preventive potential will be assessed through change in dental caries increment and oral microflora in saliva over a two year follow up period. Correlating the BMI and dental caries incidence in children could be useful to determine the effect of tooth morbidity on overall growth of the children and indicate the need for intersectoral coordination for health promotion.
