Word of mouth (WOM) communication has become a thoughtful information-sharing medium which can affect consumers' buying decisions and attitudes in the direction of product categorizations and brands. Conventional word of mouth (WOM) is an outdated method for sharing thoughts and has existed as far back as individuals traded data which now evolved to the new form of word of mouth which is the electronic word of mouth (eWOM). This study attempts to analyse the dimensions of eWOM credibility on online purchasing activities among consumers through social media. This study employs a quantitative method as the paradigm of methodology in gathering the data for this research. The questionnaires were distributed to 260 respondents. The result of this study has been analysed well as aligned with the research questions as well as the research objectives. The analysis revealed that all three major dimensions which are quality, rating and recommendation consistency had significantly underpinned the eWOM credibility on the online purchasing activities among consumers through social media and a new measurement model also had been developed. The relationship between the dimensions and the differences in the dimensions between consumers of different age and gender were also being analysed in this study where each condition showed dissimilar but accurate results. All the research questions had been thoroughly answered and the research objectives of this research had achieved as well. It is hoped that this study may contribute to the related field in the future.

Objectives: To determine the different occlusal characteristics in primary dentition of 3 to 6 year old Malay children and to create a preliminary database for future Malaysian studies as currently none of the studies has been conducted in Malaysian population regarding the occlusal features in primary dentition. Materials and method: The subjects were within the age ranging from 3 – 6 years old attending nurseries and kindergartens located within Sungai Buloh, Selangor. Sixty subjects were screened but only 47 fulfilled the criteria to be included in this study. Intra-oral examination was done to determine the terminal plane, canine relationship, overjet, overbite and primate space in the subjects. Results: Almost two thirds of the subjects (72.34%) presented with straight terminal plane. All but one subject were observed with Class I canine relationship. 61.7% subjects were with an ideal overjet and 53.19% of subjects had an ideal overbite. The mean value for primate space in the maxilla was 2.92mm and 1.60mm in the mandible. There was no significant difference between gender in all the parameters assessed. Conclusion: The results from the study shown that only few of the subjects had a tendency of malocclusion in their permanent dentition. However, a longitudinal study should be done to follow up their occlusal feature in the permanent dentition.
