en Background and Aim: This study investigated the effect of applying cyanoacrylate adhesive on clinical indices involved in the healing process of the palatal wound following free gingival graft (FGG) harvesting. Materials and Methods: In this randomized controlled clinical trial, 15 patients who required bilateral FGG harvesting were randomly assigned to two groups. In the suture group, the wound was closed by Vicryl 4-0 sutures; whereas in the control group, the wound closure and hemostasis were attained by applying a concentrated mixture of n-butyl and 2-octyl cyanoacrylate. The primary outcomes included pain according to a visual analog scale (VAS), discomfort, healing rate, early and late bleeding, ease of feeding, wound epithelization rate, and sensory disturbances within one week and three months following the surgery. Statistical analysis was performed with the Chi-square and Mann-Whitney U tests (alpha=0.05).  Results: Cyanoacrylate application on the wound was significantly faster than suturing (2.12±1.23 minutes vs. 8.42±2.24 minutes, P<0.0001). The mean postoperative pain score (P=0.015), patient discomfort (P=0.017), and healing rate (P=0.024) were significantly more favorable in the cyanoacrylate group compared to the control group during the first week after surgery. Rate of wound epithelialization showed no significant difference between the two groups (P>0.05). Conclusion: Application of cyanoacrylate adhesive to enhance the healing of palatal donor site wound decreased pain and discomfort and enhanced healing during the first postoperative week. In general, cyanoacrylate application is comparable to suturing in palatal wound healing and may be used for faster (by 6 minutes) closure of FGG wounds.   Tissue adhesives, Wound healing, Cyanoacrylates, Transplantation, Gingiva, Pain, Postoperative 71 79 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-579-2&slc_lang=en&sid=1 2022/12/13 1401/9/22 2023/08/2 1402/5/11 Mohammad Reza Karimi Department of Periodontics, Faculty of Dentistry, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran.

en Background and Aim: Keratinized mucosa width (KMW) has an essential role in peri-implant health. This study aimed to evaluate the impact of KMW on marginal bone loss (MBL) around overdenture-supported dental implants. Materials and Methods: In this cohort study, completely edentulous patients received an overdenture with implants in the maxilla and mandible. Two implants were placed in the maxilla and mandible. Ball attachments were used. KMW was measured, and gingival biotype was determined. MBL was evaluated on digital parallel radiographs taken at 12 and 24 months after loading. KMW was the predictive factor, and MBL was the outcome of the study. Data were analyzed using SPSS 21 via Pearson’s correlation test, independent t-test, and Chi-square test (alpha=0.05).  Results: Eighty implants in 20 patients were studied. The mean KMW was 2.05±0.88 mm. The mean MBL was 1.32±0.46 mm at 12 months after loading, and 1.71±0.49 mm at 24 months after loading. Analysis of the data demonstrated a correlation between MBL at 12 and 24 months after loading with KMW and dental implant diameter (P<0.001). Conclusion: It appears that narrow KMW may be associated with an increase in MBL in two-implant-supported overdentures. Gingival biotype may play a role in the detrimental effect of narrow keratinized mucosa on MBL.   Alveolar Bone Loss, Dental Implants, Gingiva, Mouth Mucosa 80 85 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-598-6&slc_lang=en&sid=1 2022/12/132023/09/24 1402/7/2 2023/08/22023/12/13 1402/9/22 Reza Tabrizi Oral and Maxillofacial Surgery Department, School of Dentistry, Shahid Beheshti University of Medical Sciences, Tehran, Iran. tabmed@gmail.com 00319475328460012270 0000000172047746 No Mahsa Safavi Private Dentistry Practice, Tehran, Iran. mahsaasafavi@yahoo.com 00319475328460012271 0000000251233141 No Mohsen MalekiGorji Oral and Maxillofacial Surgery Department, School of Dentistry, Shahid Beheshti University of Medical Sciences, Tehran, Iran. mohsen_malekigorji@yahoo.com 00319475328460012272 0000000187341833 Yes Majid Torabzadeh Department of Periodontics, School of Dentistry, Shahid Beheshti University of Medical Sciences, Tehran, Iran. torabzadeh.majid@gmail.com 00319475328460012273 0000000202124344 No

en Background and Aim: Sliding genioplasty is employed to correct a broad spectrum of chin abnormalities, encompassing horizontal and vertical augmentation and horizontal and vertical reduction. Injectable soft tissue fillers offer a less invasive alternative to genioplasty. This study aimed to compare the esthetic outcomes of chin augmentation using the abovementioned two methods. Materials and Methods: This comparative interventional study enrolled 36 patients with mild to moderate microgenia presenting to the Department of Oral Surgery, Faculty of Dentistry, Islamic Azad University of Medical Sciences. They were candidates for chin contour correction through sliding genioplasty or hyaluronic acid filler injection (n=18 in each group). Photographs were obtained before and 3 months after genioplasty surgery and 1 month after filler injection. Subsequently, the images were evaluated by 10 oral and maxillofacial surgeons, 10 orthodontists, and 20 laypersons, using a visual analog scale (VAS) to appraise facial attractiveness after treatment. Comparisons were made by independent t-test (alpha=0.05).  Results: Orthodontists and oral and maxillofacial surgeons found no significant difference between the two methods in terms of facial aesthetics post-procedure (P>0.05). However, laypersons gave higher esthetic scores to genioplasty (P=0.02). Conclusion: Based on the present results, orthodontists and oral and maxillofacial surgeons did not identify any significant difference in facial attractiveness between sliding genioplasty and hyaluronic acid filler injection. However, laypersons tended to rate genioplasty more favorably.     Genioplasty, Dermal Fillers, Chin, Cosmetic Techniques, Hyaluronic Acid 86 93 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1314-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/9 1402/6/18 2023/08/22023/12/132023/10/31 1402/8/9 Behnaz poorian Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran.

en Background and Aim: Lichen planus (LP) is a chronic inflammatory mucocutaneous disease usually diagnosed based on clinical and histopathological findings. Prognostic evaluation of malignant transformation in LP is clinically and histologically complex. Due to the inconsistent results of previous studies regarding the prevalence of dysplastic changes in LP, this study aimed to evaluate the prevalence of dysplasia in oral lichen planus (OLP) patients. Materials and Methods: This cross-sectional study was conducted on biopsy samples of OLP patients referred to Tabriz Dental Faculty from 2012 to 2020. The diagnosis of OLP was based on the World Health Organization criteria, which was confirmed by reassessment of the microscopic slides by a pathologist. The clinical subtype of OLP samples was specified based on the information present in patient files. Data were analyzed by the Chi-square test using SPSS 17 (alpha=0.05).  Results: The buccal mucosa was the most commonly involved area (27 out of 36 cases). The tongue ranked next (10 out of 36 cases). The most common clinical subtype was reticular form with 23 cases (63.9%). In 8 cases (21.9%), epithelial dysplasia was observed; of which, 7 cases were grade I and 1 was grade II. Among the observed dysplastic features, nuclear hyperchromatosis and enlarged nucleus had the highest incidence (11.1%). Conclusion: The percentage of dysplasia in OLP specimens was not high in the study population. However, considering the risk of transformation to squamous cell carcinoma (SCC), accurate diagnosis of SCC based on history, and clinical and histopathological findings is critical. In case of histopathological detection of dysplasia, long-term follow-up of patients is necessary.     Lichen Planus, Oral, Prevalence, Squamous Cell Carcinoma 94 99 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1299-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/92023/08/8 1402/5/17 2023/08/22023/12/132023/10/312023/12/20 1402/9/29 Kamal Mirmohammadi Department of Orthodontics, Faculty of Dentistry, Tehran Azad University of Medical Sciences, Tehran, Iran.

en Background and Aim: This study aimed to assess the influential factors on selection of implant treatment by patients and their correlation with outcome satisfaction. Materials and Methods: This cross-sectional study was conducted on 135 patients requiring dental implant treatment. Information regarding the influential factors on selection of implant treatment by patients was collected using a valid and reliable questionnaire, and the correlation of influential factors with outcome satisfaction was analyzed by the Pearson and Spearman correlation tests. Data were analyzed by independent t-test, Kruskal-Wallis test, Mann-Whitney test, Chi-square test, and one-way ANOVA (alpha=0.05).  Results: Advice from dentists was the most common reason (50.4%) for selection of implant treatment. Knowledge of patients about implant treatment had a significant correlation with their outcome satisfaction (P=0.003) but had no correlation with dental clinician’s satisfaction with the treatment outcome (P=0.054). Knowledge of patients about implant treatment had a significant correlation with the time interval between the date of advice from their dentist and time of seeking dental implant treatment (P=0.024), and their level of education (P<0.001). Conclusion: Patients had optimal knowledge level about implant treatment, and dentists had the most important role in knowledge enhancement of patients and convincing them to seek dental implant treatment. Knowledge level of patients had a significant correlation with their satisfaction with the outcome.   Dental Implants, Patient Satisfaction, Knowledge 100 109 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1303-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/92023/08/82023/08/10 1402/5/19 2023/08/22023/12/132023/10/312023/12/202024/06/21 1403/4/1 Kiarash Asadollahi Private Dental Practice, Isfahan, Iran. kiarash.a1993i@gmail.com 00319475328460012313 00319475328460012313 No Arash Golestaneh Department of Oral and Maxillofacial Surgery, Dental School, Islamic Azad University, Isfahan (Khorasgan) Branch, Isfahan, Iran. drgolestaneh@gmail.com 00319475328460012314 0000000344557049 Yes Mohsen MalekiGorji Department of Oral and Maxillofacial Surgery, School of Dentistry, Shahid Beheshti University of Medical Sciences, Tehran, Iran. mohsen_malekigorji@yahoo.com 00319475328460012315 0000000187341833 No Aida Kheiri Department of Periodontics, School of Dentistry, Shahid Beheshti University of Medical Sciences, Tehran, Iran. kheiri9574@gmail.com 00319475328460012316 0000000253111260 No

en Background and Aim: Third molar teeth usually erupt during the late adolescence or early adulthood and may cause various dental problems, such as impaction or overcrowding, if they do not erupt properly. This study aimed to explore the relationship between third molar impaction, and extraction, and to evaluate the impact of awareness about the associated potential risks and benefits on post-extraction complications. Materials and Methods: A cross-sectional study was conducted at Baghdad College of Dentistry, targeting undergraduate dental students. A questionnaire was sent to 333 dental students. The collected data were then analyzed using SPSS version 27. The Spearman and Kendall's tau rank correlation coefficients were used to measure the strength and direction of the relationship among the variables.    Results: Third molar impaction was more common in individuals aged 19 to 21 years. A significant correlation was found between the age of onset of symptoms related to third molars and the occurrence of impaction (P=0.006, correlation coefficient=0.144). Also, a significant correlation existed between age and extraction of impacted third molars (P=0.01, correlation coefficient= 0.268). The linear regression R2 value indicated that 14.1% of the reduction in complications was attributed to the level of awareness regarding the associated potential risks and benefits. Conclusion: This study highlighted the high prevalence of third molar impaction in young adults and the importance of its early detection and intervention. The findings underscored the significance of age and awareness in predicting and managing complications associated with impacted third molars.   Tooth, Impacted, Tooth Extraction, Molar, Third 110 116 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1315-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/92023/08/82023/08/102023/09/11 1402/6/20 2023/08/22023/12/132023/10/312023/12/202024/06/212023/10/28 1402/8/6 Maryam Hameed Alwan Department of Oral Diagnosis, College of Dentistry, Baghdad University, Iraq. maryam.h@codental.uobaghdad.edu.iq 00319475328460012311 0000000215949126 Yes Salim M Zaki Faculty of Computer Science and Information System, N28 Building, Department of Computer Systems and Communications, University Technology Malaysia, Johor, Malaysia. 00319475328460012312 00319475328460012312 No

en Background and Aim: The Graded Chronic Pain Scale version 2.0 (GCPS 2.0) has no Persian version for use on the Iranian population. Thus, this study aimed to validate the Persian version of this scale. Materials and Methods: The cross-sectional study was conducted on 160 patients with chronic pain who filled out the GCPS 2.0. The 8-item self-report GCPS 2.0 was first translated to Persian. The validity of its Persian version was examined by a group of 7 expert specialists and calculation of the content validity index. The test-retest method was used to measure the reliability of the Persian version of GCPS 2.0. The Bartlett's test, KMO index, and exploratory factor analysis were used to confirm its construct validity. The internal consistency of the questions was analyzed by calculation of Cronbach's alpha coefficient and item-scale correlation coefficient, and retesting. The relationship between the questionnaire score and demographic information of the participants was analyzed (alpha=0.05).    Results: The content validity coefficient was 0.98. The test-retest coefficient was 0.98, indicating high reliability of the questionnaire. The mean age of the participants was 38 years, and 81 (50.6%) were males. Education was found to have a significant correlation with the total questionnaire score (P<0.05) but age had no such correlation (P>0.05). Conclusion: The Persian version of the GCPS 2.0 with the omission of questions 1 and 5 may be used for assessment of chronic pain in the temporomandibular joint (TMJ) area in the Iranian population.   Chronic pain, Facial pain, Pain measurement, Temporomandibular joint disorders, Reproducibility of results 117 123 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-255-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/92023/08/82023/08/102023/09/112023/09/19 1402/6/28 2023/08/22023/12/132023/10/312023/12/202024/06/212023/10/282023/12/24 1402/10/3 Sahar Mafi Oral Medicine Department, Islamic Azad University, Dental Branch, Tehran Iran.

en Background and Aim: Anterior crossbite is the most commonly observed developing malocclusion during the mixed dentition period. Dental crossbite occurs due to over-retained deciduous teeth or their delayed exfoliation, impacted or supernumerary teeth, pathologies present around the affected teeth, or dental trauma during the primary dentition period. Various removable and fixed appliances have been used in the literature for correction of crossbite depending on the patient's age, and space availability in dental arch. Case Presentation: This paper presents a case series of anterior crossbite cases corrected using a simple posterior bite plane appliance. This appliance is simple, easy to fabricate, and takes less time to correct the crossbite. Conclusion: A posterior bite plane with a palatal plate could be an efficient solution for correction of anterior dental crossbite in the mixed dentition period. This chair-side fabricated appliance achieves correction quickly without harming the periodontal tissue. Developing malocclusions should be immediately identified by dentists to prevent complex treatment options in the future.   Malocclusion, Incisor, Orthodontics, Interceptive, Dentition, Mixed 124 128 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1328-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/92023/08/82023/08/102023/09/112023/09/192023/10/17 1402/7/25 2023/08/22023/12/132023/10/312023/12/202024/06/212023/10/282023/12/242024/02/19 1402/11/30 Neeraj Kumar Department of Paediatric Dentistry, Post Graduate Institute of Child Health, Noida, Uttar Pradesh, India. dr.neeraj001@gmail.com 00319475328460012291 0000000205171744 Yes Richa Kumari Department of Paediatric Dentistry, PGIDS, Rohtak, Haryana, India. dr.richamamc2006@gmail.com 00319475328460012292 00319475328460012292 No

en Background and Aim: Sialolithiasis is the second most frequent salivary gland disorder. However, giant submandibular sialoliths are uncommon. Herein, a case of an almond-shaped giant sialolith in the left submandibular duct measuring 3 cm x 2 cm is reported. Case Presentation: A patient was presented complaining of pain, difficult chewing, and swelling of the floor of the mouth with purulent intraoral discharge. The ipsilateral submandibular gland was tender and enlarged, resulting in acute neck swelling. Submandibular sialolithiasis of the left Wharton’s duct was primarily diagnosed. After blood testing and imaging, the sialolith was surgically removed in toto via an intraoral approach under local anesthesia. The symptoms receded postoperatively. Conclusion: Sialoliths must be suspected in patients complaining of submandibular and facial pain. A careful history must be taken and imaging should be performed to confirm the diagnosis and precisely locate the calcifications.   Submandibular Gland, Salivary Gland Calculi, Salivary Ducts 129 131 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1298-1&slc_lang=en&sid=1 2022/12/132023/09/242023/09/92023/08/82023/08/102023/09/112023/09/192023/10/172023/07/30 1402/5/8 2023/08/22023/12/132023/10/312023/12/202024/06/212023/10/282023/12/242024/02/192024/02/19 1402/11/30 Aditi Rapriya Faculty of Dental Sciences, SGT University, Gurugram 122505, Haryana, India. rapriyaaditi3006@gmail.com 00319475328460012289 0000000272926748 Yes Jitender Kumar Faculty of Dental Sciences, SGT University, Gurugram 122505, Haryana, India.

en Background and Aim: This study reviewed the prevalence of C-shaped root canal morphology in different provinces of Iran. Materials and Methods: This systematic review was conducted according to the PRISMA guidelines. Embase, Medline, PubMed, Scopus, Web of Knowledge, Google Scholar, Cochrane Library, Ovid, SID, CIVILICA, Magiran, IranMedex, and ISC electronic databases were searched for articles published from 2000 to 2021. The searched keywords included “C-shaped root canal system” and “prevalence”, “molar teeth”, “premolar teeth”, and “Iranian population”. Full-text assessment of the articles and critical appraisal were performed using the CONSORT and STROBE checklists. Gender, tooth type (first/second molar, first/second premolar), upper/lower jaw, and type of C-shaped classification were extracted from the eligible articles, pooled, and analyzed using forest plots with proportions and odds ratio with 95% confidence interval (CI). Meta-regression was performed to evaluate possible sources of heterogeneity.    Results: The prevalence of C-shaped canals was 0.06% (95% CI: 0.04-0.08). The prevalence of C-shaped canals was 0.08% (95% CI: 0.05-0.11) based on cone-beam computed tomography (CBCT) scans. The pooled prevalence of C-shaped root canal system was higher in Mazandaran (Sari and Babol) and East Azarbaijan (Tabriz) (0.10%) than other provinces.
