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. We report one potential complication of the Pfizer COVID-19 vaccine; a known case of Stevens-Johnson syndrome (SJS) that occurred after the second dose of the Pfizer-COVID vaccine alone without exposure to any other drug. Despite the initial severe adverse reaction, the patient showed full recovery. Although SJS can be associated with COVID-19 vaccinations, it's rare and the benefits of receiving the vaccinations outweigh the potential harms.

Research paper thumbnail of The accuracy of age estimation from pulp chamber/crown volume ratio of canines obtained by cone beam computed tomography images: an Egyptian study

The aging process is associated with secondary dentine deposition that reduces the volume of teeth pulp. Therefore, dental age could be recognized from the volume of pulp cavity. The aim of this study was to assess the accuracy and validity of pulp chamber/crown volume ratio of maxillary and mandibular canines in estimating age using cone beam computed tomography (CBCT) images in a sample of the Egyptian population. Results There were significant strong negative correlations between age and each of the maxillary pulp chamber volume (PCV), mandibular PCV, maxillary pulp chamber/crown volume (PCV/CV) ratio, and mandibular PCV/CV ratio (p < 0.001). Furthermore, no significant differences were detected between both sexes regarding the mean maxillary and mandibular PCV and PCV/CV ratios (p > 0.05). The best fit regression model for age prediction was as follows: age (years) = 7...

Because the direct application of a bone graft into the periodontal defect has drawbacks, such as the risk of microbial contamination and/or graft containment, a new modality of directly loading bone graft particles over the barrier membrane is now used. This study aimed to evaluate clinically and radiographically the effects of a two-layered membrane consisting of a layer of nanohydroxyapatite particles on a pericardium membrane in the treatment of stage III periodontitis, compared with direct application of a nanohydroxyapatite bone graft. Materials and Methods: Forty individuals with grade II furcation involvement were divided into two groups. Group I was treated with a two-layered membrane consisting of a pericardium membrane with nanohydroxy particles loaded onto its surface; group II was treated with direct application of a nano bone gr...

Material and methods: 15 immature permanent incisors of children (7-9 years old) had irreversible pulpitis or necrotic pulp were selected and randomly divided into 2 groups; Group I: 7 teeth were treated with Pulp revascularization and group II: 7 teeth were treated with MTA apexification. Each tooth was completely isolated with a rubber dam then access opening was done. Irrigation of the pulp chamber with 2.5% NaOCl then sterile saline and water. The root canal was then dried with paper points, triple antibiotic paste (TAP) was administered, and it was removed two weeks later with saline irrigation. In group I (revascularization) bleeding enhancement was done and MTA material was performed over the formed blood clot while in group II (apexification) the whole root canal space was filled with MTA. Finally, pulp chamber was filled with GIC filling in both groups. Conclusions: Both groups are resemble in all CBCT criteria except in dentin volume and root length in mesiodistal direction which significant in Revascularization group.

Material and methods: Immature permanent incisors with irreversible pulpitis or necrotic pulp were selected and randomly divided into 2 groups; revascularization group (Group I) and apexification group (group II). After complete rubber dam isolation, access opening was done for the selected incisor. 2.5% NaOCl then sterile saline and water were used for irrigation of pulp chamber with the same sequence. Triple antibiotic paste (TAP) was administered for root canal sterilization. In group I (revascularization) bleeding enhancement was done, and MTA material was performed over the formed blood clot while in group II (apexification) the whole root canal space was filled with MTA. Finally, pulp chamber was filled with GIC filling in both groups. Conclusions: Revascularization and MTA apexification techniques resemble in all clinical criteria while different in bone density and PL space.

size on extracted 3D radiographic volume measurement of different sizes of endodontic files and to
determine the optimal exposure parameters for volume measurement in CBCT.
Methods: Eight different endodontic k files were radiographically exposed at three different
kilovoltages using CBCT and divided into three groups, group 1 (80 KV), group 2 (60 KV), and
group 3 (50 KV), then exposed to two different voxel sizes, and divided into two groups, group a
(300 μm) and group b (180 μm). The 3D radiographic volume and the actual files volumes were
measured using ITK-SNAP software and water displacement method respectively.
Finding: Regarding changes in the kilovoltages, no significant difference (p > 0.05) was
reported between the mean of the 3D radiographic volume of groups 3 and 2 with the mean of
actual volume with a mean difference of 1.1 ±7.7 mm3 and 2.6 ±9.6 mm3 respectively. The results
for voxel size change, showed no significant difference between the mean of the 3D radiographic
volume of group (b) and actual volume group with a mean difference of 1.9 ± 7.8 mm3. In the
other hand, the difference between the mean of volume measurement at group (a) and actual group
became significant with a mean difference of 10.5 ±5.7 mm3 was found.
Conclusion: it concluded that both changes in kilovoltage and voxel size parameters affect
significantly the 3D volume measurement and reconstruction.
