Abstract

  Background and Aims: According to the concerns that people are not familiar with the word surgeon - a dentist that all general dentists use this word (surgeon - a dentist) in their office boards and given to the people expectations of this word, teaching these surgeries in the dental curriculum is limited. There is a lack of information about the public awareness of this term. As a result, the aim of this study was to determine the people awareness about the meaning of the word ‘surgeon’ on the dental offices board and its related factors in Tehran, in 2010-11.

  Materials and Methods: This study was conducted on 385 individuals by the descriptive - cross sectioned method in Tehran. Their awareness was defined and the role of relevant factors like individual characteristics, age, gender, socioeconomic (education, job, visit the dentist) were studied. Data were analyzed using K2-test.

  Results: 57.4% were female and 42.6% were male. Their average age was 50 years. The minimum and maximum age was 20 and 77, respectively. 43.6% of them had academic education and 56.4% had a diploma or less. 4.9% of them had well knowledge, 30.1% had average and 65% had poor awareness. In other words, 35% had acceptable awareness and 65% had unacceptable.

  Conclusion: It seems that people unawareness of the word surgeon - a dentist is a serious concern. Because this lack of knowledge has led to referring the people to non-expert dentist for the surgery, that may causes serious problems.

Abstract

  Aesthetic and smile design is one of the most important motivations for going to dentists and one of the most of researchers’ attention. The most important aspect of the remedy is to diagnose, especially when aesthetic is concerned and dentist should interfere the patient actively in the treatment planning. It means dentist must know what is aesthetic in patient points of view. One way to achieve this goal is digital imaging, patients images taken by digital intra oral cameras transfer to the computer and some changes done on their primary images and define all possible looks and at the end, all these looks must be shown to the patient by dentist and decide for the true remedy plan. This article introduced the software, which has prepared this aim that is easy to use and has no expense.

Abstract

Background and Aims: According to concerns of technical errors in intraoral radiographs and reports of positive effects of central ray laser pointer on the students, technical errors and shortcomings of earlier research, this study was conducted at Department of Oral and Maxillofacial Radiology of Tehran Azad University to determine the role and use of laser pointer in the technical error made by students.

Materials and Methods: This clinical trials study was carried out at the Department of Radiology, Dental School of Azad Tehran University. A total of eighty students were divided into two groups of forty. In the first group the periapical technique was taught without laser guided indicator, while in the second group laser guided indicator was applied in training the students. All students took X-rays from the phantoms. Laser guided indicator is made of one low power red laser diodes.Totally 560 X-rays were taken and the technical errors and the quality of X-rays were evaluated. Data were analyzed statistically using Mann-Whitney and Chi Square tests (&alpha=0.05).

Results: The X-rays taken by students showed significant differences in cone cutting (P<0.001), and overlapping (P<0.001) between the two study groups. In the subjective review of X-ray quality, the difference was also significant (P=0.03).

Conclusion: The use of laser guided indicator as a training aid seems to be practical for easier learning of central ray adjustment and reduction of technical errors in taking X-rays by dental students.
