This study was conducted to compare the performance of Phosphor Storage Plate (PSP) and Cone Beam Computed Tomography (CBCT) scan in detecting artificial buccal recurrent caries. Materials and Methods: Class V cavities were prepared on the buccal surface of 42 extracted human premolars and molars selected by simple sampling method. The inclusion criterion was the intact crown, and the exclusion criteria were previous restorations and significant caries. Twenty-one teeth were filled with amalgam, and the other 21 teeth were filled with composite resin. Artificial buccal recurrent caries was simulated on eleven amalgams and ten composite restored teeth. The teeth were randomly mounted on acrylic resin arches. CBCT and intraoral parallel periapical radiographs (with PSP) were taken to detect recurrent caries under restorations. Kappa coefficients were computed to evaluate the inter-observer agreement of the images taken by CBCT and PSP systems, and the sensitivity and specificity of CBCT and PSP were calculated Results: The sensitivity of amalgam and composite resin restorations in the tangential and cross-sectional plane were 18.2, 81.8, and 50, 100, respectively. The sensitivity of amalgam and composite resin restorations evaluated by PSP were 63.64 and 100, respectively. The specificity of amalgam and composite resin restorations in the tangential and cross-sectional plane were 90, 100 and 100, 100, respectively. The specificity of amalgam and composite resin restorations evaluated by PSP were 100 and 90.91, respectively. Conclusion: Considering the limitations of the study, the sensitivity of CBCT in different planes was higher than that of PSP, and the cross-sectional plane had more sensitivity than a tangential plane in the detection of recurrent caries. It is suggested that the teeth with true caries be used instead of artificial buccal caries to compare PSP and CBCT.}, Keywords = {Cone-Beam Computed Tomography, Dental caries, Radiography}, volume = {7}, Number = {3}, pages = {95-102}, publisher = {}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.32598/3dj.7.3.95}, url = {http://3dj.gums.ac.ir/article-1-318-en.html}, eprint = {http://3dj.gums.ac.ir/article-1-318-en.pdf}, journal = {Journal of Dentomaxillofacial}, issn = {}, eissn = {}, year = {2018} } @article{ author = {Ashraf, Hengameh and MojtahedBidabadi, Maryam and Noghlachi, Tannaz and Darmiani, Soheil}, title = {Controlling Postendodontic Pain in Comparison to Placebo: A Randomized Double-blind Clinical Trial}, abstract ={Introduction: After Root Canal Treatment (RCT), pain control is a concern in dentistry. This double-blind study aimed to compare the efficacy of Celebrex (celecoxib) with placebo in controlling endodontic pain. We, therefore, investigated whether or not Celebrex for pain prevention following endodontic pain therapy is better than placebo.  Materials and Methods: This randomized, double-blind study included 43 patients with symptomatic teeth. The patients consented to a prophylactic oral administration of 400mg of celecoxib, 400mg of Celebrex, or a placebo before RCT. The patients recorded their degree of pain intensity on a 170 mm Visual Analog Scale, immediately postoperative, and at time intervals of 4, 8, 12, 24, and 48h after treatment. The SPSS V. 16 (SPSS Inc. Chicago, USA) was used for statistical analysis. The data were analyzed by the Mann-Whitney and Freidman tests and Significance level was set at 0.05. Results: There was no significant difference between celecoxib and placebo group (P>0.05), whereas the mean pain score was always lower for the celecoxib versus placebo group. The prophylactic Celebrex administration significantly reduced post-endodontic pain after initiation of RCT comparing with celecoxib and placebo group.  Conclusion: The results of the study demonstrate that the Celebrex may be more effective than celecoxib for the management of postoperative endodontic pain.}, Keywords = {Anti-Inflammatory Agents, Non-Steroidal, Placebo, Pain management}, volume = {7}, Number = {3}, pages = {103-108}, publisher = {}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.32598/3dj.7.3.103}, url = {http://3dj.gums.ac.ir/article-1-320-en.html}, eprint = {http://3dj.gums.ac.ir/article-1-320-en.pdf}, journal = {Journal of Dentomaxillofacial}, issn = {}, eissn = {}, year = {2018} } @article{ author = {Karbasikheir, Mitra and Fathollahzadeh, Hossei}, title = {Assessment of Accessory Mental Foramen by Cone-beam Computerized Tomography}, abstract ={Introduction: Any additional foramen except mental foramen in the mandibular body that transfers mental nerve and vessels is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using Cone-Beam Computerized Tomography (CBCT). Materials and Methods: This descriptive study was performed on 180 CBCT images selected by simple sampling method. We checked AMF presence in tangential and cross-sectional slices. Each of them had a connection with the inferior alveolar canal in the cross-sectional slices and had an opening in the buccal surface of the mandibular body. The position of AMF was assessed on reconstructed 3D CBCT images or tangential images in eight regions of postero-superior, postero-inferior, postero-anterior, antero-superior, posterior, superior, inferior, and anterior regions. We used descriptive analysis to examine the presence of AMF based on sex and age on each side. Results: The prevalence rates of AMF were 3.3% and 5.6% in the right and left sides, respectively. There were 2 (1.1%) image samples with AMF on both sides. There were no significant difference between the presence of AMF and gender (right side P=0.42, left side P=0.73) and age (right side P=0.30, left side P=0.32).  Conclusion: There are variations in the incidence and location of the AMF; therefore, CBCT is an effective tool for 3D preoperative assessment of AMF.}, Keywords = {Mandibular nerve, Prevalence, Cone-beam computed tomography, sex}, volume = {7}, Number = {3}, pages = {109-114}, publisher = {}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.32598/3dj.7.3.109}, url = {http://3dj.gums.ac.ir/article-1-322-en.html}, eprint = {http://3dj.gums.ac.ir/article-1-322-en.pdf}, journal = {Journal of Dentomaxillofacial}, issn = {}, eissn = {}, year = {2018} } @article{ author = {Ghamari, Maryam and EbrahimiKhaneghah, Anita and Sefidi, Fateme and Ghasemi, Sharareh}, title = {Prescription of Antibiotics and Corticosteroids Following Endodontic Procedures: Study of General Dentists in Qazvin, Iran}, abstract ={Introduction: Antibiotic resistance is an alarming development. One of the major causes of antibiotic resistance is the improper prescription of antibiotics. This study sought to assess prescription of antibiotics and corticosteroids following endodontic procedures by general dentists practicing in Qazvin City, Iran.  Materials and Methods: This descriptive cross-sectional study was conducted on all 108 general dentists practicing in Qazvin City, Iran in 2016. The relevant data were collected using a questionnaire. Then, the obtained data were analyzed via Chi-square test, ANOVA, Independent t-test, and Pearson correlation test using SPSS version 20. Results: The first and second choice antibiotics prescribed by general dentists for patients not allergic to penicillin were penicillin V (35.1%) and amoxicillin (20.8%). For allergic patients, clindamycin (29.9%) and metronidazole (20.8%) were the first and second choice. Most dentists (44.2%) prescribed antibiotics for cellulitis. In case of persistence of systemic signs/symptoms of infection for more than 2-3 days, 24.7% of dentists prescribed penicillin injection and 23.4% prescribed metronidazole. For life-threatening infections, 44.2% prescribed amoxicillin plus metronidazole and 16.1% prescribed amoxicillin plus clavulanic acid. None of the responses for antibiotic prophylaxis were complete. Regarding the administration of corticosteroids, 40.3% preferred extra-oral intramuscular injection and 13% preferred tablets. Regarding contraindications for corticosteroid therapy, 9.1% of dentists gave a correct response. There was no significant correlation between gender and information (P=0.48), but the correlation between age and information was inverse and statistically significant (P=0.04). Conclusion: The majority of contributed dentists in this study had insufficient information and needed further educational courses in this respect. }, Keywords = {Anti-bacterial agents, Adrenal cortex hormones, Endodontics, Therapeutics}, volume = {7}, Number = {3}, pages = {115-122}, publisher = {}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.32598/3dj.7.3.115}, url = {http://3dj.gums.ac.ir/article-1-286-en.html}, eprint = {http://3dj.gums.ac.ir/article-1-286-en.pdf}, journal = {Journal of Dentomaxillofacial}, issn = {}, eissn = {}, year = {2018} } @article{ author = {Malekzadeh, Meisam and Nosrati, Mahsa and Maleki, Di}, title = {Assessment of Dental Student\' Knowledge of Tooth Wear: Diagnosis, Prevalence and Treatment: A Randomized Questionnaire-based Cross-sectional Study}, abstract ={Introduction: A sizable increase in the outbreak of tooth attrition and especially dental erosion has been observed. Detection of tooth wear procedure, adequate prevention, and effective interference in the early stage will avoid the adverse effect on teeth performance and elegance. Thus, the current study aimed to determine the level of awareness of senior dental students (general dentists) on the prevalence, prevention, and treatment of tooth wear.  Materials and Methods: Materials and Methods: In this cross-sectional descriptive study, 122 senior students of dental school in Rasht, Bandar-e Anzali, Pardis, Iran, were examined through census method in 2016. The data collection tools were construction questionnaire consists of 25 questions which their validity and reliability have been approved. The obtained data were entered into SPSS V. 21 and descriptive statistics, mean, standard deviation and inferential statistics, independent t-test at the significant level of P<0.05 was used to analyze the data. Results: The results of the present study showed that the majority of students had moderate awareness level. Test results showed that the students had authentic awareness only in three areas of the facet occlusion (P=0.001), in the early signs of tooth wear (P<0.001), and in occlusal loading (P=0.014).  Conclusion: The results of this study showed that students had average information about prevalence, prevention, and treatment of various tooth wear stages.

Since the DMF index cannot identify early carious lesions, the new International Caries Diagnosis and Assessment System (ICDAS) was developed. Since the ICDAS index is not included in the dental education courses in Iran, the present study aimed to assess the reliability and reproducibility of the this index after adequate training. Materials and Methods: In this cross-sectional study, 30 employees in one of the hospitals in Shiraz, Iran, were selected using the convenience sampling method as research subjects, and were examined by two examiners calibrated for DMF index and two examiners calibrated for ICDAS. The agreement between two examiners in each system was investigated using the Kappa coefficient of agreement. One of the DMF examiners and one of the ICDAS examiners examined the sample two weeks later again. The internal agreement of these examiners with their primary examinations was evaluated using the Kappa coefficient.  Results: the ICDAS index, the intra-examiner and the inter-examiner Kappa coefficients were 0.915 and 0.874, and for the DMF index, these indices were 0.903 and 0.833, respectively. These findings indicate almost a complete agreement between the examiners.  Conclusion: Both indices had good reliability and reproducibility. The ICDAS index was useful and applicable for dentists and dental students for diagnosing non-cavitated caries lesions, Therefore, integrating this index in the dental educational courses of Iranian students following further studies seems to be useful in moving toward minimal intervention dentistry.}, Keywords = {Dental Caries, Reproducibility of results, Students, Dental Cross- Sectional Studies, Education, Dental}, volume = {7}, Number = {3}, pages = {129-136}, publisher = {}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.32598/3dj.7.3.129}, url = {http://3dj.gums.ac.ir/article-1-325-en.html}, eprint = {http://3dj.gums.ac.ir/article-1-325-en.pdf}, journal = {Journal of Dentomaxillofacial}, issn = {}, eissn = {}, year = {2018} }
