The objective of this study was to measure the absorbed dose in target organs using conventional and digital panoramic radiography. In this experimental cross-over study, the Rando phantom of the Atomic Energy organization of Iran(AEOI) was exposed 54 times using conventional (Cranex Tome -Sordex), and digital panoramic (Cranex D-Sordex). radiography The absorbed doses were measured by a dosimeter (TLD’s) in the following areas: Thyroid gland, left and right Parotid and Submandibular glands, Sublingual gland, bone marrow of left and right maxilla and mandible. TLD’s were coded and the absorbed doses for each organ was determined under standard conditions in AEOI. Data was analyzed by using t-test and MANN-U-WHITNEY. In this study, the total absorbed dose in conventional radiography was 0.82±0.06 (mSiv) compared to 0.42±0.04 (mSiv) in digital radiography. The difference was statistically significant (P< 1%)and the highest absorbed dose was reported to be in Submandibular glands The lowest absorbed dose was seen in the Thyroid gland. The difference was found to be statistically significant (P< 0.01). Digital radiography can reduce the absorbed dose to critical organs.

Background and The use of intraoral direct digital radiography has been possible only the past two decades. Controlled laboratory and clinical studies are needed to determine whether the new digital system changes the diagnosis، treatment and prognosis than the conventional methods. Purpose of this study is compare the diagnostic accuracy for the detection of approximal caries of three CCD-based digital systems. seventy eight surfaces in thirty nine extract unrestored posterior teeth were radiographed under standard condition using three CCD systems، Planmecadixi 2 image receptor with Dimaxis 2. 4. 1 (Helsinki، Finland) software، Progeny dental image receptor with Cygnus media 3. 0 (USA) software and RVGai Trophy image receptor with Trophy windows access (Eastman Kodak، France). The images were assessed by three observers. True caries existence and depth determined by histological examination. Diagnostic accuracy of the systems was validated by using Kappa agreement coefficient. for approximal carries، no significant differences were found in diagnostic accuracy between three CCD systems the diagnostic accuracy of digital CCD systems is comparable with each other. The existence and depth of the lesion had no significant effect on the performance of the imaging modality. Planmeca performed consistently better than others and Progeny performed consistently better than Trophy، but the differences were not significant.

Great advantages of digital radiographic techniques have resulted in ever-increasing use of these techniques by dental practitioners. Contrast, density and other factors influecing the diagnostic quality of digital systems can be manipulated. The aim of this study was to compare diagnostic accuracy of two digital radiographic systems of Schick and Sordex in standard and high-resolution modes in the detection of interproximal caries. In this in vitro study twenty-four extracted human premolars with interproximal caries were selected and divided into four groups. Each group was radiographed using the two Schick and Sordex systems. The sensors in the two systems were fixed at 10-mm and 100-mm distances from the teeth and the tubes, respectively. All the radiograms were coded by an oral radiologist at standard and high-resolution modes in a blind manner. The teeth were sectioned in a mesiodistal direction in order to confirm caries diagnostic accuracy and determine its depth as a gold standard and coded by an oral pathologist under a stereomicroscope. Data were analyzed using Spearman’s correlation coefficient and gamma test at 95% confidence interval. There was significant relationship between the results of different digital radiographic techniques and pathologic evaluations (p value < 0.001). The highest correlation with pathologic results were observed in radiograms taken in the standard resolution mode of Schick radiographic system. Under the limitations of the present study, it can be concluded that the diagnostic accuracy of Schick radiographic system in the standard mode is highly appropriate for detection of interproximal caries.

Statement of Problems: Several methods have been presented for the prediction of mesiodistal width of the unerupted canines and premolars. Nowadays, application of digital methods is suggested in dental analysis in orthodontics.

The aim of this study was to design a software for space analysis and comparison of the accuracy of tooth measurements by digital and manual methods in an Iranian population.

By using Delphi and C++ programming languages, a software was designed. After insertion of 2 dimensional scanned images of dental casts, the software can predict mesiodistal width of the unerupted canines and premolars by using 12-variable regression equations based on the incisors and first molars. After providing 2 dimensional images of 125 dental casts in permanent dentition (75 females and 50 males), the prediction accuracy of regression equations was investigated. By providing 2-dimensional images of dental casts in 50 patients with mixed dentition, the accuracy of dental measurements was evaluated through the designed software. Moreover, the time duration of manual and digital measurements was evaluated. Data was analyzed in SPSS, version 17, using paired sample t-test for comparing the manual and digital measurements and evaluation of interobserver and intraobserver errors.

Prediction of the width of the canines and premolars by the designed software was not significantly different from manual measurement of those teeth on dental casts with digital Caliper (p >0.05). There were no significant differences between manual and digital measurement of mesiodistal width of the teeth (p >0.05). Also, there were no significant differences between intra-observer and inter-observer measurements and the speed of measurements in digital and manual methods. However, the time duration and speed of space analysis with these two methods were significantly different.

The designed software has a good accuracy in prediction of unerupted canines and premolars with equations and it is an efficient tool for predicting the mesiodistal width of the teeth as to the time duration or speed.

Diagnosis of periapical pathology is of paramount importance in enabling the clinician to provide immediate and appropriate dental treatment. Both intraoral digital radiography and film radiography are used to detect periapical pathology. The purpose of this study was to compare the accuracy of digital radiographic imaging with conventional radiography in detecting chemically created lesions. For conducting this experimental study one cow cadaver mandibular Jaw was used. After building four 1×1cm2 pools at first molar areas, 35% Hydrochloric acid solution used to create chemically lesions. The designed time for chemically lesions was 4, 12, 24 and 36 hrs following acid exposure. Then, 1 digital and 1 conventional image with E-Speed film was taken from each half-jaw and images evaluated by five examiners. Wilcoxon signed Ranks test used for statistical analysis. The results of this study showed that diagnosis were more precise in detecting lesions with RVG than conventional radiography. This difference was statistically significant (p<0.05). Regarding the acceptable quality of digital radiographs comparing to conventional radiographs we suggest using this method for detecting bone lesions.
