Roentgenographic observations in 19 cases of tooth roots displacement to the maxillary sinus using 4 technics of periapical, topographic, Waters and panoramic projection. It was indicated that, 1). Left maxillary first molar root was forced into the antrum more frequently than the roots of other teeth. 2). Roots were displaced into sinus more frequently in males than females. 3). To identify the root, panoramic and topographic were helpful projection. Waters projection was of little or no value, for the root fragment. However it is useful in that it may provide indirect confirmatory evidence of an antral perforation and reveals the presence of sinus infection.
The project was designed to study the efficiency of the Manual Processing Solution produced by Department of Radiological Technology, Tropical Medicine, Mahidol University. (Product Solution). It was divided into 2 parts. 1) to determine the numbers of satisfactory radiographs that could be produced before degradation of the solution occurred. 2) to compare the diagnostic quality of 150 radiographs processed by the Product Solution and Kodak Solution. It was indicated that in view of 50 radiographs processed during the experiment, the 120 ml. Product solution seem to be capable of processing radiographs of satisfactory quality for five days. Clinical comparison between 150 radiographs developed by the two solutions using difference developing time was indicated equal radiographic quality of both solutions during the developing time between 2-4 minutes.
