Comparison of Salivary pH After Consuming Milk of Origin Vegetable vs Cow's Milk in Children

The study was carried out in 21 first grade primary school children, 100% aged 6 years, 52.4% were female. They were given 5 types of milk, each one was measured on different days (Monday cow's milk, Tuesday coconut milk, Wednesday almond milk, Thursday soy milk, Friday rice milk)

About this study

  • The study was carried out in 21 first grade primary school children, 100% aged 6 years, 52.4% were female.
  • The group was given a brushing technique using a model and 2 videos were shown to reinforce the brushing technique and explanation of what was going to be done in the study.
  • Supervised tooth brushing was performed in a group of 5 people.
  • They were given 5 types of milk, each one was measured on different days (Monday cow's milk, Tuesday coconut milk, Wednesday almond milk, Thursday soy milk, Friday rice milk).
  • Each child was given 7 plastic cups each day and asked to pour their saliva into the cup when instructed.
  • The samples were taken with pH indicator strips and the result was recorded in personalized tables.

Primary outcomes

  1. Sociodemographic results

    Time frame: 1 hour the sociodemographic data of all the children were taken.

    The study was carried out in 21 first grade primary school children, 100% aged 6 years, 52.4% were female.

  2. pH results

    Time frame: The average time of pH evaluation for each milk per child was an hour and a half.

    30 minutes after tooth brushing, each child was asked for the first saliva sample (basal pH measurement).

    After taking the basal pH, each child was given a glass with 50 ml of the milk to be measured.

    Saliva samples were measured with pH indicator strips and the result was recorded on custom charts.

    The pH was taken at 5, 10, 20, 30, 40 and 50 minutes.

    The normality distribution test (Shapiro-Wilk) was applied to the quantitative variables, with p = 0.0001, so that the data present a non-parametric or free distribution.

    To assess whether there were differences between the pH of the groups, the Kuskal-Wallis test was applied. For basal pH, p = 0.0001, therefore the null hypothesis is rejected and we conclude that the basal pH level is different in the five milks. Average basal pH:

    Rice milk 7 Cow milk 6.9 Almond milk 6.6 Soy milk 6.4 Coconut milk 6
