Change in dental caries status on provision of high fluoridated tooth paste; A triple blind randomized clinical trial.

Abstract

Objective: To investigate the change in dental caries status on provision of high fluoridated tooth paste after 24 months. Study Design: Triple Blind Randomized Clinical and Controlled. Setting: Private School of Gulshan Town, Karachi. Period: January 2018 to January 2020. Material & Methods: A cohort of regular school children aged 12-15 years studying in classes 6-9 were included. Through simple random sampling, 412 subjects were purposively allocated to Group A (n=202, intervention group) and Group B (n=210, control group). A pre-trial market survey was conducted to identify the fluoridated toothpastes available followed by the laboratory testing of fluoride concentration through Atomic Absorption Spectrometry. Dental examination was performed by a single examiner on mobile dental units under sunlight in the school ground using sterilized dental mirror, probe and tweezers at baseline and then after 8, 16 and 24 months employing the World Health Organization recommended Decayed Missing Filled Teeth index. Results: The mean age of the recruited participants was 12.91±0.82 having 209 males and 203 females. The mean DMFT scores observed over 24 months were 1.25 in group A and 1.42 in group B. At baseline it was 1.10 ±1.50 and 1.11±1.43 which gradually increased to 1.32±1.57 and 1.59±1.96 in group A and B respectively at last follow-up examination. Conclusion: This trial has identified no significant change in the overall dental caries status; however, the mean decayed score in both the interventional groups decreased on provision of high fluoridated tooth paste.
