Background: Proper education in oral and dental health behaviors and preventive orthodontics is vital for preventing dental diseases and orthodontic abnormalities. Since children spend much time in schools and in contact with their teachers, the current study aimed to assess the level of awareness about preventive orthodontics among school hygiene instructors in Sari, Iran.
Methods: Seventy-one hygiene instructors were included in this semi-experimental study with a pre-test and post-test design. The participants completed a questionnaire before any intervention. A one-day workshop about preventive orthodontics was held for the instructors, and an educational CD and pamphlet were provided for them. The participants were asked to answer the same questions after a month. Data were compared and analyzed with SPSS 22, using paired t-test and chi-squared test.
Results: The findings revealed that the training could significantly increase the level of orthodontic awareness among hygiene instructors (P<0.001). However, the participant’s level of education and years of experience was not significantly associated with their level of awareness (P>0.05).
Conclusion: Considering the importance of health education, efficient training should be provided for school hygiene instructors to increase their awareness in the field of preventive orthodontics.

Background and aim: The aim of present study was to predict post treatment space available of mandibular arch and compare this method of measurement with the previous methods. Materials and methods: Pretreatment lower dental arch models of 33 patients attending to the department of orthodontics of Tehran University of medical sciences were randomly selected. Two conventional methods of brass wire and sectional way were done for estimating space available in traditional method. In predictive method two mathematical arch forms, β-function and the sixth degree polynomial function were selected as the based arches. Post treatment arch perimeter predicted according to these arch forms separately and finally the results were compared with traditional method of brass wire.Results: According to this study, two traditional methods are so closed to each other and also two predictive methods, but differences between traditional method and predictive methods measurements were considerable. Conclusions: Using of post treatment arch parameters would be useful to predict post treatment space available in arches, and also detecting arch form, the position of the teeth, the retention requirements and so on.
