ABSTRACT
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

In restorative dentistry, selecting the proper material is an important factor for clinical success. The objective of this study was clinical evaluation of survival time of three tooth color materials in primary anterior teeth. In this interventional clinical trial study, 94 deciduous anterior teeth [36 teeth in boys, 58 teeth in girls] belonging to 3-5 year old children in Pediatric Department of Mashhad Faculty of Dentistry, Iran were selected. Selective dental materials included compoglass, glass-ionomer Fuji II LC, and composite resin. The data were analyzed with Kaplan-Meyer and Log rank test. compoglass had the highest survival time in comparison with composite and glass-ionomer. Nine months retention rate for teeth restored with compoglass, composite resin and glass-ionomer were estimated: 95%, 21%, and 12.5%, respectively. Compoglass can be a suitable material for anterior primary teeth restoration
ABSTRACT
Gloves protect the dental healthcare worker from direct contact with microorganisms in the patient's mouth and on dental setting surfaces; they also protect the patient from potential pathogens on the hands of the clinicians. This study was performed to evaluate the permeability of three types of examination latex gloves after treatment of patients in pediatric department of Mashhad school of dentistry. A total of 60 pairs of three types of gloves [Supa,, Medic-Dent and super Max] and five gloves of each type as control were randomly selected. The effective barrier properties were investigated following one hour treatment including fluoride therapy, amalgam and tooth colored restoration and pulp therapy. The effect of sex and the difference between working and non working hands were assigned too. The permeability of the case and control groups was determined by an electrical test. The voltage of each glove was registered at a current of 0.6 mA, using salt electrolyte solution. The data were analyzed using SPSS statistical software [t-test and ANOVA]. Comparison of mean voltage of used glove with control in each type showed no significant difference except in Super Max [P=0]. Unlike supa and Medi-Dent gloves, greater permeability was detected in super max glove after treatment. The mean voltage of working and non working hand between gloves was not significant [P=0.19]. According to this study there was not any difference in permeability of Iranian glove [supa] before and after use
