The paper "Oral Health Education In Schools: Promoting Health Agents by Garbin, Garbin, and Lima" is a brilliant example of an article on medical science. The methodology of the experiment is explicitly detailed. It will be possible to replicate the study on other subjects. The population considered for this study involved pre-school children and their parents. Since the experiment was aimed at studying the influence of oral health education of children on their family, the population chosen for this study is appropriate. Since the participants required for this experiment were just pre-school students and their parents, there was no need for specifying any sampling strategies to enlist participants. However, the study failed to describe why only pre-school children were selected. The study had intended to analyze 119 preschool children and their parents. However, since only 63 parents agreed to be a part of the study, the sample size available for analysis reduced from 119 to 63. This sample size is fairly small and inappropriate for deriving significant inferences. The study involved human subjects who were preschool students and their parents. The students were oriented by way of oral health education but were unaware that they were a part of an experiment. This is assumed and is not specified by the authors. The parents who enrolled in the study consented via an informed consent form. The measurement variables are not specifically defined. The influence of child education on the habits of their family is being measured. The children’s cognitive, emotive and psychomotor abilities in maintaining dental hygiene were manipulated with the help of an oral health education program. The effect of the manipulation was measured by studying the parents’ perceptions of the education program via a questionnaire. While it is stated that frequency and percentages analysis is being used for statistical analysis, the actual method used is not specified. However, the use of the EPI INFO ver.3.2 software is specified. The confidence intervals are specified wherever required.It can thus be concluded that the experiment is well laid out and replicable. However, it is lacking in appropriate details on the type of statistical analysis used and the reason for choosing only preschool children. The sample size is small and the measurement variables are not specifically defined.
