A study of student awareness of radiation protection skills at jazan university
Nouf H Abuhadi

DOI:10.4103/1658-743X.292033  
Objectives: To evaluate radiology students’ awareness of ionising radiation exposure and its related risks during common diagnostic imaging procedures, to evaluate students’ radiation protection knowledge for assessment of educational processes and clinical training. Materials & Methods: A total of 200 senior students at the Diagnostic Radiology Department were requested to complete a questionnaire consisting of 26 questions. The data were analysed using the statistical package for social sciences software (SPSS). Results: The response rate was 90.5% (181 students). Awareness level depended on student grade point average (GPA), age, and relevant courses attended in radiation. Gender and marital status did not predict awareness of radiation protection standards. Conclusion: Our results showed a general lack of knowledge regarding radiation protection for fourth level students, which slightly improved in the subsequent levels. Including specific courses of radiation protection for medical and dental students is highly recommended. Such courses will improve skills specific to professional handling of radioactivity as well as radiation awareness.

LIP repositioning surgery and its sequelae in the treatment of a gummy smile: A case report
Saad M Alqahtani
January-June 2019, 4(1):21-24
DOI:10.4103/1658-743X.292031  
Excessive gingival display, also known as “gummy smile” has several etiologies. A gummy smile is a drawback for the esthetics and social behavior of various patients. Lip repositioning surgery confers predictable results. However, lip repositioning surgery is indicated in patients with a hyperactive upper lip, while gummy smile owing to altered passive tooth eruption and vertical maxillary excess need to be addressed with crown lengthening and orthognathic surgeries, respectively. Lip repositioning surgery is an uncomplicated procedure, which reduces the muscular pull on the upper lip to achieve minimal display of dento-gingival unit while smiling. Nonetheless, few authors question the relapse of the lip position. This report describes a case showing satisfactory results with lip repositioning surgery and after 1 year follow-up shows a nonsignificant relapse in the position of the upper lip. Hence, lip repositioning surgery is a safe and predictable approach for gummy smiles with negligible relapse.

Unconventional single - visit interim prosthesis – A case report

Replacement of missing anterior teeth is of utmost importance for esthetics and function. Fixed partial dentures (FPDs) are the most commonly used prostheses but are usually associated with failure either due to faulty fabrication, inadequate retention, or negligence in maintenance by the patient. During fabrication of new FPDs, transitional prostheses have an important role in providing esthetics and function to the patient. The aim of the current work was to provide adequate esthetics to a patient during the treatment period. During the transition phase of fabrication, a new fixed partial denture, patients should be provided with an interim prosthesis. In this case report, interim prosthesis was fabricated using acrylic resin. The contours of existing fixed prosthesis were duplicated, and an unconventional interim prosthesis was fabricated in single-visit for a young adult female patient with failed anterior fixed partial dentures. Step by step treatment was carried out to fabricate the interim prosthesis for the patient. The interim prosthesis fabricated was clinically acceptable. After insertion of the prosthesis, the patient and her family were satisfied with the esthetics. During follow-up as well, the patient was satisfied with the prosthesis and did not show any discomfort. The unconventional approach for the fabrication of an interim prosthesis used herein for a young adult female patient fulfilled the requirements of the patient and successfully protected the tissues during the fabrication of the final prosthesis.

Root resorption after orthodontic treatment: A literature review
Abdulaziz Alshahrani
January-June 2019, 4(1):1-5
DOI:10.4103/1658-743X.292029  
One of the most feared complications after orthodontic treatment is the external root resorption. Root resorption leads to shortening of root and thus, the integrity of teeth arch is broken down. Both the cervical and apex zones of the roots can be affected by it due to orthodontic forces involved in the tooth movement. The future of the teeth involved may also be compromised due to orthodontic treatment. It is necessary that the patient is pre-informed about the root resorption’s risks as a result of orthodontic treatment. It is possible to detect the orthodontic-induced root resorption both during the active phase of treatment and after the orthodontic treatment. The degree and severity of orthodontic-induced root resorption are dependent on a number of factors involving environmental factors and the host himself. The paper talks about the root resorption, its degree of severity, mechanism, detection methods, and significant correlation with individual susceptibility, tooth structure, fixed appliance treatment, orthodontic tooth movement, orthodontic force, and treatment duration.

Severity of periodontal diseases and gingival crevicular fluid (gcf) volume of saudi patients in pubertal stage being treated with some restorative dental materials

DOI:10.4103/1658-743X.292030  
Objective: The restorative materials on tooth surfaces are predisposing factors for periodontal diseases due to an increase in plaque formation and inflammation of the adjacent gingiva. The attachment of dental plaque to dental restorations is more than that to the tooth surface as a result of specific characteristics of restorative materials like surface free energy inherent and surface roughness. The present study designed to assess the severity of periodontal diseases and gingival crevicular fluid (GCF) volume of the Saudi patients in pubertal stage who treated by some restorative dental materials. Subjects and Methods: This clinical study conducted on 120 patients aged between 15-21 years old. The study included three equal groups (40 patients each), 50% males and 50% females. The examined restoration types were: composite resin, amalgam and glass ionomer fillings. After six weeks of dental restorations, the following periodontal parameters: plaque index (PLI), gingival index (GI) and clinical attachment loss (CAL) in mm recorded for each restored tooth, then the gingival crevicular fluid (GCF) collected . Finally, the data analyzed by SPSS to evaluate the periodontal status. Results: The results of the present study revealed that there were differences in all periodontal parameters in the comparison between group I, II and III but without statistical significance differences except CAL (p < 0.5), moreover, there were significant differences in GCF volume between group I, II and III.(p<0.05). Conclusion: After six weeks we concluded that there was a significant impact of composite resin, amalgam and glass ionomer fillings on the clinical parameters and GCF volume where we observed that the clinical parameters and GCF volume of amalgam restorations more higher than composite resin and glass ionomer fillings restorations.
