Content analysis of Islamic Republic of Iran television food advertising related to oral health: appeals and performance methods

Today, electronic mass media such as television [TV], influence behavioral patterns of their audiences. This study aimed to evaluate what messages on food advertisements related to oral health were transmitted [appeals] and how they were transferred [performance methods and artistic techniques] in Islamic Republic of Iran Broadcasting [IRIB]. In this cross sectional study, broadcasted advertisements on 4 important channels of Iran TV were recorded for a week from 8 am to 12 pm in 2012. The content and volume of food advertisements were investigated using a researcher-made check list. Advertisement group [food, non-food], food group [non-cariogenic, cariogenic], advertisement appeals [rational, emotional, and humor content], advertisement performance methods [hard-sell, soft-sell, presenting confirmation of Ministry of Health and Medical Education], and artistic technique were assessed. For variable comparison in groups a chi squared test and t-tests were used via SPSS software. Frequency of food advertisements [14.9%] were less than non-food advertising. Non-cariogenic food advertisements had higher frequency [12.09%] compared to cariogenic food [2.8%]. Rational appeal in advertising of non-cariogenic food had the most frequency [64.9%]. In contrast emotional appeal for cariogenic food was used more frequently [85.5%]. For cariogenic foods, a soft-sell approach was used more frequently [95.5%]. The most common artistic technique used in food advertising was music. Chemical and mechanical dental plaque control materials had a very low frequency [0.2%]. Advertising of cariogenic foods in Iran TV has low frequency

Assessment of protective effect of amorphous calcium phosphate-caseine phosphopeptide and silicone oil against the erosive property of iron drop: an in-vitro investigation in primary teeth

One of the complications of Iron drop recommended for 6-24 months children is the potential reduction in microhardness of primary tooth enamel because of low pH. The objective of this study is to assess the protective effect of amorphous calcium phosphate caseine phosphopeptide [ACP-CPP] and silicone oil in primary teeth. Thirty extracted primary anterior teeth were divided into three equal groups. The initial micro hardness was measured by Vicker's microhardness tester. The first group without a protective layer and the second and third group after application of ACP-CPP and silicone oil respectively, were immersed in iron drop. Microhardness was remeasured. One tooth in each group along with a tooth not exposed to iron drop were randomly chosen for SEM qualitative analysis. Analysis was performed with Repeated measures ANOVA with SPSS-18. All groups exhibited significant decrease of micro hardness [p=0.001], however, no contrasting pattern was found between various groups. Neither ACP-CPP nor silicone oil could not provide a significant protection against micro hardness reduction after exposure to iron drop
