[Evaluation of oral health knowledge, attitude and behaviour of employees in Mashhad Health Centers No 1, 2 and 3 in 2006]

Health is the base for Development and also health level is affected by the development. Through Culture Promotion attracting Public cooperation, we can change their knowledge, attitude and behaviour about oral and dental health. This study aimed at determining the level of knowledge, attitude and behaviour among staff of health and treatment centers No1, 2 and 3 of Mashhad city about oral and dental health.

After completing of the questionnaires by the staff, the data were collected and then analyzed by Kruskal Wallis statistical test. This study showed that among the 186 cases studied, 23.1% had good knowledge and 19.9% had poor knowledge about oral and dental health, while only 2.2% had good attitude and 9.2% of the cases had good behaviour. This study showed that the level of knowledge about oral and dental health had a statistically significant relationship with educational level [P=0.004], so that the dentists had the highest level of knowledge and the technicians had the lowest level. This study revealed that among these three health centers in Mashhad, health center No 2 staff had the lowest knowledge level. According to the low knowledge, attitude and behavior of the staff of the health centers No 1, 2 and 3, establishment of strategies for continuous education courses seems necessary

[Comparsion of primary enamel discoloration caused by the use of three different iron drops [An in vitro study]]

Iron deficiency anemia is the most common health problem in childhood. One way to meet this important need in the body is to add iron supplement in our diet. This supplement is known as Ferrous sulfate in Iran. Teeth blackness in children especially after taking Iron drops and the parent`s dissatisfaction is one of the most important reasons for visiting a dentist. Generally, parents have an idea that taking iron drops by the children is the cause of tooth decay, therefore they limit this vital supplement in their children`s diet. The aim of this study was to compare of primary enamel discoloration caused by the use of three different iron drops. Quantitative stage: In this first stage of the study, 60 anterior primary teeth were selected and the necessary preparation were made. The level of iron absorption in etch group and the intact one were determined by Atomic absorbtion in 248.3 nonometers long wave and resolution of 0.062ppm. Qualitative stage: In this stage, 7 teeth were put under scan electron microscope [SEM] after the primary preparation. There was no significant difference in the iron absorption on the healthy teeth, between foreign iron drop and the one produced by Mashhad school of pharmacy. But the level of absorption in Iranian Iron drop was significantly higher [P=0.01]. The absorption in etched teeth increased which might have been due to increased surface- [P=0.0001]. There was no significant difference between experimental drops in the etched teeth. Iron drops that produced by Mashhad school of pharmacy had less discoloration on the primary enamel teeth. The more increased surface because of etching, the more change in color was observed and this was most prominent in Iranian iron drop. Color discoloration increased with frequency of iron drop intake
