Witt's appraisal and ANB angle are cephalometric analysis indicators, which play essential roles in diagnosing class III malocclusion. In the current study, the correlations among Witt's and ANB cephalometric indices and the upper pharyngeal airway width has been investigated in individuals with class III malocclusion.<br /><strong>Materials and methods:</strong> This cross-sectional study was performed on 110 lateral cephalometric radiographs of 11-14-year-old patients during 2017-2020. The upper pharyngeal airway width was determined by p index (the shortest distance between the soft palate and the posterior pharyngeal wall) and the t index (the shortest distance between the tongue base and the posterior pharyngeal wall) through lateral cephalometric radiography. The data were designated by central tendency indicators and measures of dispersion. The Shapiro-Wilk test evaluated data normality. Also, the Spearman correlation coefficient was used to determine the correlation rate.<br /><strong>Results:</strong> Investigating the correlations among indicators showed a direct but dramatically low relationship in ANB and p values and Witt's and p values. However, these relationships were not statistically significant. There was also an inverse linear relationship between ANB and t values and Witt's and t values. Nevertheless, the results showed the mean values of p, t, ANB, and Witt's indices were higher in females than males, yet, the differences in p and ANB values were not statistically significant.<br /><strong>Conclusion:</strong> Results showed the correlation coefficients among the upper pharyngeal airway width, and ANB and Witt's analyses were not significant. These results can reinforce the probability of class III malocclusion inheritance.http://www.ijsrdms.com/article_113433_6de002b8e5309f35d0069768eaa384f8.pdfTehran: International Journal of Scientific Research in Dental and Medical SciencesInternational Journal of Scientific Research in Dental and Medical Sciences2676-54972320200901Is Low-Level Laser Therapy Effective for Complications of Mandibular Third Molar Surgery?

They are considered a benign condition that can occur anywhere in the body; in the microscopic examination, this cyst reveals a cavity lined by stratified squamous epithelium resembling an epidermis, a lumen filled with degenerating orthokeratin. It is sporadic in the oral cavity, representing only 1.6% of all cysts. Its appearance in the buccal mucosa has been poorly reported. The purpose of this article is to describe a case of a 22-year-old male with an epidermoid cyst in this unusual location. This entity should not be ruled out of lesions that may occur in the oral cavity, even when its incidence is extremely low.http://www.ijsrdms.com/article_110273_071ef1b1375315bbc760927251e2956a.pdfTehran: International Journal of Scientific Research in Dental and Medical SciencesInternational Journal of Scientific Research in Dental and Medical Sciences2676-54972320200901Severe Scabies after COVID-19: A Case Report9710011366510.30485/ijsrdms.2020.237728.1069ENAbdul Razaq HirmanDepartment of Dermatology, Faculty of Medicine, Kandahar University, Kandahar, Afghanistan0000-0003-3564-1433Ferooz Ahmad MuradDepartment of Dermatology, Faculty of Medicine, Kandahar University, Kandahar, Afghanistan0000-0003-1580-8929Abdul Aziz NikzadDepartment of Urology, Faculty of Medicine, Zhengzhou University, Zhengzhou, China0000-0003-1036-3350Journal Article20200701Scabies is defined as a pruritic skin condition caused by an infestation of itch mite Sarcoptes scabiei that is exceptionally contagious; however, there is no exact figure on its prevalence. A six-year-old girl was presented to the Dermatology department of Zahid Maiwand clinic in Kandahar City, Afghanistan. The chief complaint of patient was severe itch at night and rashes on the skin. The skin lesions were "face and body papules, papulovesicles, pustules, nodules, and seborrhea for 15 days" in May of 2020. Ten days ago, the girl was diagnosed as COVID-19 after a PCR test; the patient's fever and body aches were slowly subsiding while the rash started to appear; it was extremely itchy at night; after taking a complete history. It was found that other family members were also showing scabies symptoms such as itching at night and small burrow type skin lesions.

Its etiology is not entirely clear, but an association with a mutation in the TMC01 gene has been reported. On the other hand, the dentigerous cyst is the odontogenic cyst of the most common development in the jaws. It results from the accumulation of fluid between the reduced epithelium of the enamel and the crown. They are generally solitary lesions, rare to find them bilaterally and multiple, and not reported in the literature about this syndrome. This article presents a bilateral dentigerous cyst description in the mandible of a patient with Pascual-Castroviejo syndrome. A 14-year-old male patient with a diagnosis of cerebro-fascio-thoracic dysplasia (Pascual-Castroviejo syndrome), presenting a bilateral lesion in the posterior mandible, with a year of evolution. An incisional biopsy was performed in the larger lesion, and the diagnosis was a dentigerous cyst. Subsequently, under general anesthesia, enucleation and curettage of the lesions associated with the second and third molars of the first, second, and third quadrant were performed, along with the involved teeth' extraction. Periodic postoperative controls were carried out, and after six months, there were no signs of recurrence. The appearance of cystic lesions of the jaws associated with the Pascual-Castroviejo syndrome is rare. Further genetic studies are crucial to determine the association between both entities.http://www.ijsrdms.com/article_114623_0f52fc971c8e21db3d9218d05ac5c58f.pdfTehran: International Journal of Scientific Research in Dental and Medical SciencesInternational Journal of Scientific Research in Dental and Medical Sciences2676-54972320200901Virchow’s Node in a Different Presentation10510611162710.30485/ijsrdms.2020.232606.1059ENAmir Keyvan SazgarSchool of Medicine, Tehran university of Medical sciences, Tehran, Iran0000-0002-7502-0183Sahar KarimpourDepartment of Internal Medicine, School of Medicine, Tehran university of medical sciences,Tehran, Iran0000-0003-2669-6942Mahsa AbbaszadehDepartment of Internal Medicine, School of Medicine, Tehran university of medical sciences,Tehran, Iran0000-0003-2748-6111Samaneh ParsaDepartment of Internal Medicine, School of Medicine, Tehran university of medical sciences,Tehran, Iran0000-0002-6851-488XJournal Article20200524Gastroesophageal(GI) malignancies are among the common malignancies in the world.
