Processing Techniques

The application of certain digital processing techniques offers the possibility of extra accuracy in the interpretation of paraclinical examinations of this type, with profound implications in the diagnosis as well as in the hierarchy of the treatment plan. The purpose of this study is to identify the type of imaging processing for the identification of pathological elements from orthopantomographies and articular tomographies. A number of 20 orthopantomographies and 15 temporo-mandibular joint tomography have undergone through various image enhancement techniques. Various methods of image enhancement (enhancement) have been used for those procedures whereby it becomes more useful in the following aspects: specific details are highlighted; noise is eliminated; the image becomes more visually attractive. The workings were done in Corel PhotoPaint 7.0, using the automatic procedures available.The choice of a particular type of image enhancement technique has been selected for each type of pathology found in orthopantomographies or articular tomography, providing the best accuracy for an optimal imaging interpretation that underpins a precision diagnosis.Of the most useful imaging processing in the optimization of the orthopantomographic image accuracy the point-to-point transformations are to be noted. The image processing proposed in this article focused primarily on improving the radiological image attributes to highlight specific anatomical structures, and secondly, the contour detection, where it was necessary for the diagnostic purposes as well.

Irreversible Pulpitis

Introduction. Apexogenesis is the process of shaping the root for 3 years after the appearance of the crown in the oral cavity. The condition for continuing this process is to preserve the vitality of the tooth. Injury, caries or disorders of the anatomical structure may cause necrosis or irreversible pulpitis. The assumption of endodontic treatment of immature permanent teeth is to create a mineralized barrier closing the lumen of the canal (apexification) or continuing the development of the root (revascularization). Regeneration of the pulpo-dentinal complex allows for the increase of root length, thickening of its walls and narrowing of the apical hole. This can be achieved by a new treatment method – revascularization. The advantage of this therapeutic method is to avoid all the defects arising after endodontic treatment with the use of apexification, i.e. tooth brittleness, susceptibility to root fracture, discoloration of the tooth tissue. Aim. The aim of the study was to evaluate the modern method of treatment of necrosis or irreversible pulpitis in immature permanent teeth by revascularization in the aspect of tissue healing, regeneration of the pulp-dentinal complex, thickness growth and the length of the root walls. Material and methods. The study was conducted among 7 children aged 7-12, including 3 girls and 2 boys. Revascularization was performed in 7 teeth. The study involved 6 central incisors and 1 premolars. During the treatment, polyurethane paste and MTA were used. The control group consisted of patients who were tested using MTA due to the inability to perform revascularization. 23 patients aged 7-13 were qualified to the control group. Control tests were carried out after 3, 6, 12 months after treatment. The clinical condition of the tooth and the radiological image were evaluated. Results. Radiological examination was crucial in assessing the effectiveness of the revascularization procedure. It confirmed the decrease of periapical lesions, increase in root length, root wall thickness and closing of the apical hole. During the clinical examination, the subjective feelings of the patient, discoloration of the tooth's tissues, reaction to tapping, tooth mobility, depth of the gingival pocket, tenderness of the appendage and tightness of the final filling were controlled. The obtained results were compared with the control group. Conclusions. Revascularization is a promising treatment for immature permanent teeth due to the increase in the length of the root and the thickness of its walls. As a result, the teeth after treatment are more durable and are better for long-term maintenance in the mouth. The procedure of revascularization has some limitations at the stage of patient’s qualification for the procedure. If it is not possible to perform this procedure, the alternative is to apexify using MTA.

Pleomorphic adenoma (PA) is a salivary gland tumor that may rarely occur in the nasal cavity. It can be a clinical diagnostic dilemma in many instances due to many possible differential diagnoses. We report the case of a 26-year-old female who presented with a 3-year history of a right nasal growth associated with ipsilateral nasal blockage, nasal pain, and rhinorrhea. Radiological image showed a mild enhancing lesion in the right nasal cavity. The patient underwent a lateral rhinotomy with wide excision of the mass. Histopathological exam was consistent with PA. Nasal PA is a rare entity and should be suspected as a diagnosis for intranasal tumors.

Background Because of an increasing number of boards and conferences, the number of second opinion readings of externally acquired image data is growing dramatically. In this review article we intend to give medical and legal recommendations for the documentation and interpretation of externally acquired radiological data for second opinions and board presentations based on German jurisdiction. Method Using the FAQ format as a dialog between radiologists and medical legal experts, we answer the most crucial questions regarding correct documentation and interpretation for externally acquired radiological image data based on an up-to-date literature search. Results Based on the unity of radiological image data and the corresponding written report according to the radiation protection law, the primary report should be present when composing a second opinion. If the primary external report is not present, this should be mentioned as a limitation. All radiological second opinions should be documented in written form. This is especially important in cases of discrepant findings. Legally, the attending physician is responsible for selecting the radiological opinion. The radiologist should not rely on the written primary report without personal reevaluation. Legally, it would be considered radiological malpractice if the external image data and previous image data are not evaluated personally. Conclusion From a legal point of view, there are explicit recommendations regarding thorough documentation of a second opinion as an independent medical service in all cases.
