A novel formula for estimating the vertical dimension of occlusion using panoramic radiography.

Background: This study aimed to develop a new formula to easily estimate the vertical dimension of occlusion (VDO) by using the distance between the mental foramen on a panoramic radiograph.

Subjects And Methods: A total of 508 dentulous subjects were selected from outpatient dental clinics at the College of Dental Medicine, Al-Azhar University. The vertical dimension of the occlusion was measured using a single calibrated calliper.

Comparison of perceived masticatory ability in completely edentulous patients treated with thermoplastic complete denture versus single implant-retained mandibular overdenture: a single-center prospective observational study.

Background: This study aimed to compare the perceived masticatory ability (PrMA) in completely edentulous patients (EDPs) with thermoplastic conventional complete dentures (CDs) versus single implant-retained mandibular overdentures.

Methods: The current study was conducted in the outpatient Prosthodontic Clinic, Faculty of Dental Medicine, Al-Azhar University, Cairo, Egypt. PrMA was evaluated in 45 completely edentulous patients (46% males, mean age 50.

Clinical and Radiographic Evaluation of Locally Delivered Plant Stem Cells for Treatment of Periodontitis: Randomized Clinical Trial.

Background: Periodontitis causes the destruction of soft and hard tissues. Stem cells have immense potential in regenerative cellular therapy. This clinical trial aimed to evaluate clinically and radiographically the effectiveness of the local application of Edelweiss stem cells as a nonsurgical treatment for stage III periodontitis.

Clinical and radiographic study of the use of cross-linked gelfoam matrix in the treatment of dehiscence-like defects in Stage III periodontitis.

Background: This clinical study aimed to overcome the difficulty of graft fixation and limited blood supply for dehiscence defects regeneration by using a cross-linked gelfoam matrix jointly with collagen membrane and xenograft.

Materials And Methods: The study included twenty dehiscence-like defects in maxillary anterior teeth with ≥4 mm facial bone loss and ≥5 mm clinical attachment loss (CAL) in patients suffering from Stage III periodontitis. Sites were treated with regenerative surgery using a cross-linked gelfoam matrix with glutaraldehyde, xenograft, and collagen membrane.

Morphometric Analysis of the Midline Mandibular Lingual Canal and Mandibular Lingual Foramina: A Cone Beam Computed Tomography (CBCT) Evaluation.

Background: This study aimed to evaluate the midline mandibular lingual canals and foramina and their anatomic variations using CBCT scans.

Methods: This study used retrospective analysis. A total of 320 CBCT scans were used to evaluate the study parameters, which comprised the presence or absence of the mandibular lingual foramen (MLF)/mandibular lingual canal (MLC) and its category, the distance between the buccal cortex and the start of the MLC, the distance between the inferior border of the mandible and the superior border of the foramen at its lingual and buccal terminals.

Stevens-Johnson syndrome post second dose of Pfizer COVID-19 vaccine: a case report.

Coronavirus disease 2019 (COVID-19) began in December 2019 and has affected millions of people all over the world. Respiratory illness in the form of severe pneumonia, in addition to multiorgan failure and death, is the clinical spectrum of COVID-19. Although there are no specific therapeutic agents for COVID-19 infection, the COVID-19 vaccine reduces morbidity and mortality associated with COVID-19 infection and is generally well tolerated.
