Indian J Med Res. 2015 Dec;142(6):742-6. doi: 10.4103/0971-5916.174567.


Background & objectives: Infantile diaper dermatitis is a common, acute inflammatory reaction of the skin around diaper among infants. This study was undertaken to compare the effect of topical application of Bentonite and Calendula creams on the improvement of infantile diaper dermatitis.

Methods: This double blind randomized controlled trial was undertaken on 100 patients of infantile diaper dermatitis. The 100 participants were randomly assigned into two groups of 50 each, and were prescribed the coded medicine. The mothers were trained to apply the cream and level of improvement was judged by observing the affected area on the first visit and then after three days of receiving treatment.

Results: The mean age of infants was 6.45±5.53 months in Calendula group and 7.35±6.28 months in Bentonite group. Overall, 88 per cent of lesions in the Bentonite group started improving in the first six hours while this rate was 54 per cent in Calendula group (P<0.001). The risk ratio for the improvement in the first six hours was 2.99 folds in the Bentonite group. Also, lesions in 86 per cent infants in the Bentonite group and 52 per cent in the Calendula group were completely improved in the first three days after treatment (P<0.001).

Interpretation & conclusions: Our results showed that in comparison with Calendula, Bentonite had faster healing effect and was more effective on the improvement of infantile diaper dermatitis (IRCT ID: IRCT 2012112811593N1).
