“…The beam produced by the circular collimators are larger than the size of 2 intraoral film, whereas that by a rectangular collimator is slightly larger than the size of two intraoral film. [8] Majority of the participants of this study, both PG students and interns are not aware of the best type of collimators. This may be because of their poor clinical experience.…”

Background: Recognition of the harmful effects of radiation and the risks involved has led to the development of radiation protection protocols and guidelines. Aims and Objectives: To assess the knowledge and perception of postgraduate students and interns toward radiation protection protocols in dental colleges. Materials and Method: This study was conducted among 200 individuals (Equal number of interns and PG students). Each participant was given a structured questionnaire (with 20 questions). Answers to the questions were in the form of multiple choices. Correct responses to the questions were allocated one mark while wrong responses received no mark. First 10 questions were to evaluate the knowledge of dental students in radiation biology and remaining ten questions were to assess how well the participants were correlating their knowledge to practice dental radiography. Results: The knowledge and perception level in regard to radiation biology and radiation protection protocols were noted to be higher with postgraduate students than in the interns. Conclusion:The majority of interns and minority of postgraduate students had limited knowledge about various aspects of radiation biology and radiation protection protocols, and they should implement recent and appropriate radiation protection practices and guidelines. This helps in protection of both the patients and operator from the harmful effects of radiation.

“…[1][2][3][4][5][6][7][8][9][10][11][12] Dentists and orthodontists have been concerned about the radiation exposure from radiographs. [13][14][15][16][17][18][19][20] In addition, there have been questions about orthodontists' level of responsibility in discovering incidental abnormalities on radiographs. [21][22][23][24][25][26][27][28] Thus, the frequency of pathologies on lateral cephalograms that have been discovered by practicing orthodontists could be a factor in the decision to obtain those images.…”

Objective: To determine the frequency of significant pathologies on lateral cephalograms discovered by orthodontists during their careers. Materials and Methods: A five-statement survey was sent to the 417 active and affiliate members of the Edward H. Angle Society of Orthodontists. The survey asked orthodontists to identify any significant radiographic pathology that they had discovered on lateral cephalograms during their careers to date. The data were analyzed statistically. Results: Of the 417 surveys, 201 were returned for a 48% response rate. Ninety-nine respondents or 49.3% of the sample had discovered at least one significant pathology. Of the 1.3 million patients observed by the orthodontists in the sample, 268 patients (0.02%) with significant pathologies had been identified. Younger orthodontists had a statistically greater potential to discover pathologies than older orthodontists. The general types of pathologies discovered were musculoskeletal (38%), glandular (28%), and dental groups (12%). Conclusions: About 50% of orthodontists will likely discover a significant, potentially life-affecting pathology on a lateral cephalogram. (Angle Orthod. 2011;81:58-63.)

“…2, indicating considerable scope for further collimation [67]. As rectangular collimator decreases the radiation dose by up to fivefold as compared with a short circular one [68][69][70], so radiographic equipment should equipped with rectangular collimation for periapical and bitewing radiographs [61]. As an X-ray beam is divergent, increasing this distance reduces the divergence within the patient and therefore reduces the volume irradiated.…”

“…The thyroid gland, one of the most radiosensitive organs in the head and neck region, is frequently exposed to scattered radiation and occasionally to primary beam during dental radiography [69]. Thyroid skin exposure can be reduced by 33-84% in adults and 63-92% in children by using thyroid shield [70].…”
