Answer 1

a

Health behaviour: Tooth brushing among pre - schoolers

Research question: Effectiveness of manual versus electric toothbrush on incidence of dental carries in preschool children (3-6 years of age)

Research variable manual versus electric toothbrushing

Outcome variable: incidence of dental carries

Hypothesis:

Research hypothesis: There will be significant difference in incidence of dental carries in pre-schoolers using electric tooth brush as compared to pre-schoolers using manual tooth brush

Alternate hypothesis: There will be no significant difference in incidence of dental carries in pre-schoolers using electric tooth brush as compared to pre-schoolers using manual tooth brush

Research design: Non experimental research design

Method of data collection: Dental examinations by licensed dentists before recruiting participants for study

Obtaining data about regularity of brushing from mothers by asking them to fill a tally sheet and collecting information on monthly basis

Distributing hourglass calibrated to 2 minutes for ensuring time taken for brushing by the preschooler

Dental examinations by licensed dentists after 6,12 and 24 months

Analysis of data:

Descriptive statistics for presenting characteristics of participants

Inferential statistics for testing hypothesis

· Continuous variables using Student's t test

· Categorical variables using chi‐square test
