SARS-CoV-2 genome variations and evolution patterns in Egypt: a multi-center study.

A serious global public health emergency emerged late November 2019 in Wuhan City, China, by a new highly pathogenic virus, SARS-CoV-2. The virus evolution spread has been tracked by three developing databases: GISAID, Nextstrain and PANGO to understand its circulating variants. In this study, 110 diagnosed positive COVID-19 patient's samples, were collected from Kasr Al-Aini Hospital and the Children Cancer Hospital Egypt 57357 between May 2020 and January 2021, with clinical severity ranging from mild to severe.

Prediction of neurosensory disorders after impacted third molar extraction based on cone beam CT Maglione's classification: A pilot study.

Background: Surgical difficulty assessment in the extraction of impacted mandibular third molars is a constant challenge for oral surgeons.

Aim: The first aim was to apply Maglione's new classification on patients that needed surgical extraction of impacted mandibular third molars, and the second aim was to study the correlation of the classification classes with the occurrence of postoperative neurosensory disorders.

Materials & Methods: The present prospective clinical trial pilot study was conducted on patients attending oral and maxillofacial surgery clinics from February 2017 until January 2018 for the surgical extraction of impacted lower third molars.

Case Report: An association of the gubernacular canal, supernumerary tooth and odontoma with an impacted canine on cone-beam computed tomography.

This report describes a clinical case of asymptomatic compound odontoma in the anterior left side of the maxilla associated with an impacted canine and supernumerary tooth with a gubernacular canal of a 47- year-old female with no relevant medical history. Cone-beam computed tomography (CBCT) was performed for precise three-dimensional localization of each structure and assessment of their spatial relationship with the associated structures before surgery. The treatment protocol involved surgical enucleation of the odontoma and open extraction of both impacted and supernumerary teeth.

Case Report: Ectopic third molar in the maxillary sinus with infected dentigerous cyst assessed by cone beam CT.

Ectopic development of teeth in nondental areas is uncommon, especially in the maxillary sinus. A panoramic radiograph is the routine diagnostic radiographic examination performed for this type of eruption, although cone beam computed tomography (CBCT) is highly recommended for further localization of the ectopic tooth and assessment of the characteristics of any associated lesion before a surgical procedure. We report a case of a 13-year-old female student who presented with purulent discharge posterior to the upper right second molar with a bad taste and foul odour.

Relationship of Mandibular Ramus Dimensions to Lower Third Molar Impaction.

Objectives: The aim of this study was to investigate the mandibular ramus features that could contribute to the etiology of mandibular third molar impaction.

Materials And Methods: Two hundred and forty subjects were divided into two groups: impacted group: 115 subjects presented with an impacted mandibular third molar, and control group: 125 subjects with the normal mandibular third molar eruption. Digital panoramic radiographs were used, and four angular and twelve linear measurements were done.

A Retrospective Analysis of Radiographic Jaw Findings in Young Women; Prevalence and Predictors.

Aims And Objectives: To determine the prevalence and types of jaw pathologic findings as detected in panoramic radiographs of a sample of young women attending a teaching hospital in Al Madinah Al Munawarah, Saudi Arabia, and to determine the most important factors that predict the occurrence of jaw pathologic findings.

Materials And Methods: The electronic clinical files of a representative sample of female patients who attended the outpatient dental clinics were retrieved. Patients were aged 18 to 25 years.

Incidental cone beam computed tomographic findings among Taibah University patients, KSA: A retrospective study.

Objectives: The aim of this study was to retrospectively evaluate the prevalence, type, and location of incidental findings by cone beam computed tomography (CBCT) scans. This study was performed to diagnose dental problems in the female population at Taibah University Dental Clinics (TUDC), KSA.

Methods: A series of 150 consecutive CBCT scans were identified between January 2014 and February 2016.

Radiographic assessment of impacted teeth and associated pathosis prevalence. Pattern of occurrence at different ages in Saudi male in Western Saudi Arabia.

Objectives: To assess the prevalence of both impaction and associated pathosis in a Saudi population in Al-Madinah, Saudi Arabia based on digital panoramic radiographs.

Methods: This study was carried out from December 2013 to February 2015. Panoramic radiographs of 359male patients attending the Oral Diagnosis Clinics, Faculty of Dentistry, Taibah University, Al-Madinah, Saudi Arabia were reviewed.
