Evaluation of randomised controlled trials published in Indian specialty dental journals for statistical testing of baseline differences: A meta-epidemiological study.

Background: In randomised controlled trials (RCTs), the application of a test of significance to compare the baseline differences between the intervention groups is a common practice, though it has been condemned by many researchers.

Objective: This study aimed to assess the proportion of RCTs on human participants comparing the baseline differences between intervention groups using the test of significance in nine dental specialty journals published in India and to estimate the proportion of studies reporting baseline demographic and clinical characteristics in a table.

Materials And Methods: RCTs published in nine dental journals published by dental specialty associations of India were screened.

Effect of Kangen and reverse osmosis water on dental plaque, salivary pH and salivary Streptococcus mutans counts: a randomized-controlled trial (A preliminary study).

Purpose: The present randomized-controlled trial was conducted to assess the effect of Kangen water and reverse osmosis (RO) water on dental plaque, salivary pH and salivary Streptococcus mutans count.

Materials And Methods: This randomized control trial was conducted for 14 days on 24 randomly selected participants from the pool of undergraduate dental students. Participants were randomly divided into two groups of 12 each: the Kangen water (pH 9) group and the RO water group.
